How to improve the use cycle of asphalt mixing station?

.

　　The metering system of the forced intermittent asphalt mixing equipment is a hot aggregate metering bucket facing the bottom of the hot aggregate storage compartment, which is hoisted under the hot storage silo by four weighing sensors. Different specifications of sandstone materials in accordance with the grade quality ratio successively fell into the metering bucket, after the cumulative amount of bucket and reached the set value after the metering bucket discharge door opened, unloading in the asphalt mixing equipment. When the metering bucket falls into the material, the resistance value of the strain gauge in the sensor changes, so that the voltage value of the sensor changes, the change value is passed to the ADC0809 for A/D measurement conversion, and the converted signal is transmitted to the microcontroller. The single-chip microcomputer transmits the measured value to the industrial computer, and the industrial computer sends the control signal to the microcontroller or MCU according to the program itself to produce the corresponding control signal and output, control the actuator to complete the corresponding action. 　　3. 3. 2 installation of the required machine Administrative Vehicle 1 (for contact and sporadic acquisition), 35t, 50t crane each 1 parts, 30m rope 1, 10m retractable ladder 1, crowbar, sledgehammer, hand saw, electric drill, grinding wheel machine, wire clamp, all kinds of plate hands, seat belts, horizontal ruler and other commonly used tools, ZL50 loader 1 units.

How is the asphalt mixture made?

.

The optimum temperature for the mixing, transport, laying and compaction of asphalt pavement depends on the hardness (viscosity) of the asphalt, the time and length of transport to the project site and when it is compacted. Secondly, in the whole operation process, the relevant staff should maintain a serious and responsible work attitude, carefully check the various instruments, indicators, belt machine and batching transmission system operation status, once found that the asphalt mixing station has problems to immediately stop operation, and timely reporting problems. In case of emergency, be sure to cut off the power supply and deal with the problem in time. Finally, the staff also need to regularly maintain the asphalt mixing station equipment maintenance management, so that the equipment is in the best working condition, daily maintenance in time to check the existence of safety hazards, and to eliminate, to ensure that the asphalt mixing station safe and efficient work. First of all, after starting the equipment, to make it run empty for a period of time, in this process of operation, the operator should pay attention to observe its operating status, until it is determined that the asphalt mixing station mixing system is normal, can start the formal operation, in general, cannot load start. The first aspect is the time to feed. Therefore, if you want to improve the production efficiency of the asphalt mixing station, then the user in the process of operation will need to regularly check the butterfly valve and related electrical components, to ensure the normal operation of the entire system, and ensure the smooth connection between the powder hopper and the mixer, to ensure the normal feeding time. Secondly, the user should also pay attention to check the mixing machine internal blade liner integrity, the location of raw materials and delivery time period, etc., to ensure the appropriate mixing time. Asphalt Mixing station, also known as asphalt concrete mixing equipment, plays an important role in pavement engineering construction. For this set of professional production of asphalt concrete equipment, can be divided into many forms. Asphalt mixing station can produce asphalt mixture and color asphalt mixture and so on. So, what are the issues to be aware of when operating such a device? Finally, all operators should also be required to wear helmets in accordance with the regulations. When the work is over, the power supply should be turned off and the operating room should be locked. When handing over, it is necessary to pay the status of the shift, and the asphalt mixing station operation situation to do a good record. So far, Mobile Asphalt Plant mixing station in China has gone through a long period of development, so that, but also accumulated a wealth of production experience, technology is becoming more and more mature. In fact, we can also be very intuitive to see that the original low production efficiency has now gradually developed into a high efficiency and low energy consumption of the development characteristics. Let's take a look at the specific content together. In addition, the third aspect of the problem is that the user should pay attention to ensure the appropriate discharge time in the course of operation. In addition, it is recommended that we prepare sufficient transport vehicles according to the production capacity and transport distance of the asphalt mixing station to ensure timely transportation so as not to affect the progress of the project. Then, in order to protect the production safety, in the entire operation process, do not allow personnel outside the staff to appear in the work environment, at the same time, asphalt mixing station operators must use the correct way to operate, such as the discovery of faults, should be repaired by professionals. It should also be noted that the operation is not allowed to open the safety cover and mixing cover inspection, lubrication and other work, also can not directly put tools, sticks into the mixing bucket in the grill or clean up. During Hopper lifting, it is important to ensure that there are no personnel in the area below it. In addition, in the daily maintenance and maintenance work, attention should also be paid to the staff's personal safety issues. For example, in the high-altitude maintenance asphalt mixing station, more than two staff should be carried out at the same time, and fasten the seat belt, do a good job of the necessary safety protection. In the event of bad weather such as strong winds, rain or snow, high altitude maintenance operations should be stopped. From the above content can be learned that the asphalt mixing station market in China has also undergone many changes, and with the development of the economy and the passage of time, the market of Vortex Air pump products is also constantly heating up. However, when we build a good station, how can we operate to ensure high productivity? Next, we will discuss this issue. In fact, there are three aspects that will have a greater impact on the production efficiency of the mixing station.

Analysis of circuit troubleshooting tips for asphalt Mixing station

n

No matter what type of rational mixer, if the steel quality of its vibrating screen screen and the reasonable size of the sieve mesh and sieve hole, do not pay attention to the installation accuracy of the screen, and so on, the first stirring effect will not be ideal, and then affect the use of asphalt, so that the selection of high-quality higher wear-resistant screen is the basic condition for It can also reduce costs. In the course of road construction, it is bound to use asphalt mixer, presumably we will not be unfamiliar with this. In addition to the overall quality of the machine, the selection and use of components also play a key role, will affect the construction quality and production costs. The screen in asphalt mixer is used as an example to specify. n Judging from years of production experience, in the work of asphalt mixing station, there will be some failure problems, usually due to electromagnetic coil problems and circuit problems caused. Therefore, in the actual production of the work, we must distinguish between these two different faults, and take the corresponding solutions to deal with each other. Asphalt mixing station to maintain normal operation, then in the production process, all aspects must be kept normal, of which, the normal circuit system is to ensure its stable operation of an important aspect. Imagine that if there is a problem in the circuit during the actual construction of the asphalt mixing station, then it will affect the whole project. When it comes to asphalt mixing station, it is not new to us, this is a special asphalt mixing preparation of the unit equipment, in fact, the real lack of understanding is its air road system, even the asphalt mixing station Air road system will often appear accumulation failure is not very clear. It turns out that only by properly maintaining the various systems of the equipment will it be possible to achieve efficient production and good benefits. n In the case of air compressors, there is often a slow rise in pressure caused by the damage to the inverse valve, piston ring, or blockage of the air filter. For piping, leakage will also occur due to joint leaks and hose breakage. The failure of the decompression valve is due to the low pressure adjustment, which is caused by the fracture of the pressure-regulating spring or the rupture of the diaphragm. n The concrete performance is that can not shift or commutative action is relatively slow, valve core seal ring damage is serious, the pilot solenoid valve inlet, exhaust hole is blocked, can not normal commutative and so on. n If we check the asphalt mixing station and find that it is due to the problem caused by the electromagnetic coil, then we should use the meter first for troubleshooting. The specific method content is: the measuring instrument and the electromagnetic coil voltage connection, measure the actual value of the voltage, if consistent with the specified value, then prove that the electromagnetic coil is normal. If it does not match the specified value, we also need to continue the troubleshooting, such as the need to check the power supply and other forming switch circuit is abnormal, and processing. So what if it's a combustion system with fuel as fuel? Such a system, not only can save production costs, but also for oil temperature control is relatively easy to achieve. The combustion system of asphalt mixing station with fuel fuel has good economic benefit, and it can also obtain suitable combustion ability by controlling the oil quantity of fuel oil. n For the user, naturally do not want this kind of thing to happen, so if we use the asphalt mixing station work, if there is a circuit problem, we must take the right approach to deal with it in a timely manner. The following article will provide a detailed description of this issue, under which I can help you. . In the use of the process, we must ensure that the rotation direction of the mixer is consistent with the direction indicated by the arrow, if there is no discrepancy, should also be adjusted by correcting the motor wiring. After the boot, often pay attention to the mixer parts of the operation is normal, the same is true when the shutdown, can not occur abnormally. . Some Asphalt Drum Mix Plant mixer manufacturing enterprises use cheaper ordinary steel manufacturing of inferior screen, ignoring the use of special wear-resistant steel wire weaving and carefully crafted wrapping process and other requirements, resulting in short service cycle, seriously affecting the normal operation of the unit. Security for any device is the focus, asphalt mixer Of course there is no exception, today to share with you is also this knowledge, that is, asphalt mixer safety operation norms, may wish to pay attention to it. n It is important to note that no matter what kind of fault, we should ask professionals to carry out testing and processing, so that the operation can ensure the safety of operations, but also conducive to maintaining the safety and smoothness of asphalt mixing station.

Asphalt Mixing Station operator precautions

: The temperature of the mixture is one of the standard of conformity assessment of the mixture, the temperature is too high or too low is scrap, can not be used. Therefore, how to control the temperature is one of the basic skills that the operator should possess. . There is also part of the improvement of the heat conduction oil furnace, because the original use is the combustion of diesel heat conduction oil furnace, this time replaced with a coal-fired heat conduction oil furnace, can greatly save costs. . The second is to retrofit the former diesel tank and lay the heat conduction oil coil at the bottom of the tank so that it can be used to heat the heavy oil to the desired temperature. At the same time, it is necessary to set up a separate electronic control cabinet for the whole system to realize the automatic switching between diesel and heavy oil, and to protect the system with the warning mode of acoustic and light alarm. The third influencing factor may be due to a problem with the vibrating screen. Generally speaking, the material must go through the screening before entering the respective hot silo. If it can not be fully screened, it is easy to form a screen blockage and other problems. At this time, the particles that do not pass through the sieve will produce a barn, and the flow rate over the General Assembly causes the fine aggregate in the mixture to increase, and finally makes the asphalt mixture grading change, resulting in the reduction of the production rate of the asphalt mixing station. . In short, the operator should pay close attention to the changes in raw materials, often check the screen, find problems to solve in a timely manner, according to the characteristics of the mixing station and other factors, the measurement range to the best state. Careful consideration of other factors affecting the grading, so as to ensure the mix ratio of the airflow grinder mixture. The first influencing factor should be the defects in the quality of raw materials used in the construction site, which do not meet the production requirements. The usual situation is that the coarse aggregate grading deviation is too large to meet the grading requirements, the water and soil content in the fine aggregate is many, the mineral powder is too wet or damp, and the asphalt temperature is too low or too high, thus affecting the production efficiency of the asphalt mixing station. . 　　C. Dust accumulation 　　Dust from the bottom of the dust collector accumulates to the bottom of the bag, which accelerates the wear of the bag. At this time should check the dust discharge device operation status and check whether there is leakage, and take appropriate measures. 　　D. Bag Wear 　　The inside of the cloth bag becomes dirty because the dust into the inside through the cloth bag, which also causes wear and tear on the cloth bag. In addition, if it is found that there is dust accumulation at the powder mouth, in order to prevent the breakage of the cloth bag, to check the dust collector's powder feeding device, and replace the worn cloth bag. 　　1) Dust leakage 　　Open the cover plate at the top of the bag dust collector to check for wear and breakage of the cloth bag, and take appropriate measures. Remove dust from the upper cavity of the bag and check if any dust enters the bag inside. The external wall of the cloth bag adhesion of too little dust, indicating that the atmosphere anti-blowing too often. Extended bag Compartment cleaning interval. . 　　2) Problems with cloth bags 　　A. The temperature of dust-containing gas is too high 　　The temperature of the dust-containing gas cannot exceed the maximum allowable temperature of the bag. Equipment used in the cloth bag can generally withstand 200 ℃ high temperature, if the inlet temperature exceeds this value, should open the emergency spare wind door to introduce cold air for cooling >　　B. >Humidity is too high >　　The moisture will clog the cloth bag >So dry the wet bag or replace the new cloth bag >In many construction processes, there is a difference between actual productivity and rated productivity >In particular, some large equipment, such as Mobile Asphalt Plant mixing plant equipment, sometimes the actual productivity varies greatly, for this phenomenon, may be some problems in the production process > >Secondly, the operator should accumulate a wealth of experience, can foresee most of the mechanical failure, early resolution, eliminate hidden dangers >After the failure, should be able to accurately judge the timely elimination, to ensure the normal use of machinery >To do this, the operator in addition to the timely maintenance of machinery in accordance with the procedures, but also to do the following points >The fourth factor may be caused by an incorrect operator operation >Mainly for some time regulation, does not meet the standard production procedures, so will affect the entire output, resulting in low efficiency of asphalt mixing station >In addition, the field operators violate the operating procedures or lack of circuit professional maintenance knowledge, short circuit or illegal debugging, resulting in line impassable, signal failure, will affect the normal production of asphalt mixture.

Asphalt Mixing station, also known as asphalt concrete mixing equipment, plays an important role in pavement engineering construction. For this set of professional production of asphalt concrete equipment, can be divided into many forms. Asphalt mixing station can produce asphalt mixture and color asphalt mixture and so on. So, what are the issues to be aware of when operating such a device? Secondly, in the whole operation process, the relevant staff should maintain a serious and responsible work attitude, carefully check the various instruments, indicators, belt machine and batching transmission system operation status, once found that the asphalt mixing station has problems to immediately stop operation, and timely reporting problems. In case of emergency, be sure to cut off the power supply and deal with the problem in time. The last trend is the independent development and creation of accessories related to asphalt mixing plant equipment, especially for core components. We must realize that the core supporting parts have always been the main factors restricting the development of China's construction machinery industry. Only by constantly strengthening the research technology in this area, can we get rid of the bondage of foreign parts manufacturers. In the asphalt mixing plant, which will involve the use of a lot of different equipment, it is clear that different equipment has the same role. And for mixers, what kind of role does it play? For this issue, we will then give you a brief introduction, I hope to be able to help you. Let's take a look at what's in the specific content. Therefore, if we want to further improve the production level and production standards of asphalt mixing stations, then it is necessary to attach great importance to this aspect. Not only should we be able to ensure adequate supply of raw materials, energy and accessories, but we should also strictly inspect their specifications, varieties and quality. In other words, it is necessary to strictly grasp the quality of the production materials, in order to complete the important production work on this basis. We know that asphalt mixing plant equipment enterprises if they want to maintain a competitive advantage, then not only should follow the main trend of existing development, but also continue to improve their own technical level, product quality, at the same time, we need to pay more attention to brand building, to establish its own development needs of the sales system. So, the asphalt mixing station industry in the future will show what kind of development trend? Asphalt Mixing Station production work is a very complex project, which will involve a lot of knowledge, of course, in the process of production, will inevitably be affected by a number of factors. Today, what we mainly analyze for you is the impact in terms of materials. In fact, the quality of the materials produced is a material condition to ensure that the Asphalt Drum Mix Plant mixing station is in normal production. In addition to the above requirements, the operator should also regularly check the transmission part of the lubrication situation, especially the bearing part, to ensure good lubrication, in order to ensure the good operation of the equipment, and finally to complete the work of the Asphalt mixing station task. . First of all, the operator should be proficient in the mixing plant some of the structure and operating principle, on this basis, strict control of the production details, especially the measurement system, due to the quality of measurement operations, directly affect the technical indicators of asphalt mixture. The third trend is the asphalt mixing station equipment with the function of recycling waste asphalt mixture. We can see that the recycling rate of waste asphalt mixture recycling in the market is increasing at present, so China's demand in this area is also rising. The fourth trend is to move in the direction of automatic, intelligent control. This will make our production work more efficient and more convenient to operate. . In addition, we need to be equipped with a number of consumables and other key components. In this case, even in the asphalt mixing station production process, there is an unexpected words, can also be timely remediation, so as not to delay the construction period. In addition, in the daily maintenance and maintenance work, attention should also be paid to the staff's personal safety issues. For example, in the high-altitude maintenance asphalt mixing station, more than two staff should be carried out at the same time, and fasten the seat belt, do a good job of the necessary safety protection. In the event of bad weather such as strong winds, rain or snow, high altitude maintenance operations should be stopped.

The latest control system of intermittent asphalt mixing station

About the asphalt mixer layout, should be in accordance with the pile plane layout plan operation, the error must not be greater than 2CM. For the asphalt mixer to configure 110KVA construction power and φ25mm water pipe, to ensure that its power supply and all transport management normal and stable.

In addition, the system selection of accurate and stable scale module, with a complete or more than the measurement accuracy of brand-name asphalt equipment, mixing station to maintain stable and reliable work is the key. Here to introduce to you is a gap type asphalt mixing station, and the most interesting is its control system, which is based on PLC on the basis of a stable and reliable control system, can achieve long time, heavy load stability work. Let us tell you about the various features of this technology. Its powerful protection tips, including equipment chain protection, mixing cylinder overweight protection, asphalt overweight protection, storage silo and other material testing, metering warehouse discharge inspection, so that the mixing station operation process has a strong guarantee. At the same time, it also has a powerful database storage function, for users to query the printing of raw data, statistics, and the implementation of the parameters of the settings, adjustments. As an important part of asphalt mixing station equipment, the cold material supply system plays an important role in the application, so do you know what kind of role the different parts of the system play in each other? In the actual work, for these different parts, how should we do a good job of maintenance? Next, let's take a look at the relevant content. Asphalt Mixing Station commutator valve failure is not complex, that is, the conversion is not timely, gas leakage, electromagnetic pilot valve failure and so on, the corresponding reasons and solutions are of course different. In order to change the commutative valve is not timely phenomenon, generally because of poor smoothness, spring jammed or damaged, oil or impurities stuck in the sliding part, etc., it is necessary to check the status of the oil mist, lubricating oil viscosity, the need to replace lubricating oil or other parts. Finally, in order to ensure the normal operation of the whole system, we also need to check regularly, and adjust the tightness of the aggregate belt appropriately. In the adjustment, should pay attention to the belt on both sides of the screw should also maintain a tight moderate, to avoid tightness inconsistent and produce belt running deviation. When the asphalt mixing station is running, it is also necessary to pay attention to observe the working status of the part, if the abnormal problem is found should be dealt with in a timely manner. This new control system can be animated to show the mixing station batching process, the level of the material, the opening and closing of the valve and, of course, weight, so that each process can be at a glance. Typically, the equipment can be continuously produced in an automatic manner, and the operator can also manually suspend manual intervention. In addition to manufacturing, commissioning and installation needs to be operated by the installer, the maintenance of asphalt cans for asphalt mixing stations and other work must also be managed by professionals, at the same time, they must operate in strict accordance with all safety rules, before the operation, must be proficient in the relevant requirements, It is also based on the requirements and safety instructions for storing and handling thermal bitumen. Before the construction of asphalt mixer, the top surface miscellaneous fill in the construction range of asphalt mixer should be removed, and the elevation of the site should be kept dry and flat to meet the design requirements. If the surface is too soft, should strengthen the foundation, prevent the construction machinery instability, to ensure that the pile frame vertical. The above is a brief introduction to the cold material supply system in the asphalt mixing station, I believe that we now have a new understanding of the system, but also hope that in the future work can be used.

When the asphalt mixer is positioned and ready, the mixer motor can be turned on, and the wet spray method can be used to pre-stir the soil to sink it, and wait until the stirring shaft sinks to the design depth before starting with 0. 45~0. 8m/min Speed Drill grouting. Asphalt Mixing station also has commutator valve, the general situation will not appear problems, so before also did not carefully understand its solution. But in the actual use of the time, but encountered this aspect of the failure, how to deal with it? After a long period of use, the commutator valve is prone to valve core seal ring wear, stem and seat damage phenomenon, resulting in gas leakage in the valve. At this point, the seal ring, stem and seat should be replaced, or the commutator valve should be changed directly for new. In order to reduce the failure rate of Mobile Asphalt Plant mixer, usually also need to strengthen maintenance.

How to control the temperature of mixing material in asphalt mixing station reasonably?

In addition to the above two factors, the water content of raw materials is also an important factor that can not be ignored. If the water content of raw materials is high, then it is very difficult to control the temperature in the production process of asphalt mixing station. In addition, the technical status of the combustion system, the pressure of the fuel pump, as well as the size of the injection, will affect the temperature of the mixture. If there is a problem with wear, leakage, or blockage in the combustion system, the performance of the system will be reduced.

Asphalt mixing equipment Stirring speed is indeed very fast, the corresponding stirring power is certainly very high, but the specific amount must be measured in a certain way, so as to determine the use of asphalt mixing equipment range. There are also many methods to measure the stirring power of asphalt mixing equipment, but the relative error is smaller than that of electric motor reverse torque measurement and strain measurement method. Asphalt Mixing station is a very complex system, for each working procedure should be carried out in accordance with the standard norms, today for everyone to prepare for the asphalt mixing Plant rotary cup work and daily maintenance and maintenance work content, I hope to be able to help everyone's work. In addition, the management of different regions should be carried out as required. Whether it is office area, work area, or warehouse and other places should be kept clean and orderly. The main structure in the Construction contract section should be set up before the signage, indicating the name, construction owner, technical person in charge, as well as project supervision and other content signs. Asphalt mixing station, different materials should be stored separately, and there are signs indicating key information, for special profiles need to add a certain amount of protective facilities. In the working process of Asphalt Mixing Plants mixing station, the quality condition of the mixture will often be related to its final construction quality. So we need to improve the quality level of its mixture as much as possible, and the temperature of the mixture is one of the criteria for the conformity assessment of the mixture. In other words, if the temperature is too high or too low, it can cause the mixture to become scrap, can not meet the needs of only the use. When the motor of the asphalt mixing equipment begins to run, the electromagnetic moment acting on the rotor of the motor and the electromagnetic moment effect on the motor stator are equal, but their direction is the opposite. Therefore, as long as the torque acting on the stator is measured, the torque on the rotor can be obtained, and after deducting the friction torque on the rotor bearing, the torque is stirred. According to the conversion relationship between torque and tangent strain, the torque value of the mixing shaft can be easily obtained after data processing, and then the friction torque of the seal, bearing and so on, which is measured by the no-load experiment, is the amount of torque actually consumed by the asphalt mixing equipment during the stirring process. Secondly, to ensure the smooth operation of the road. In the work road, do not allow turbulence, the construction site should remain flat, and set up road signs and signs. In general, it is required that the site site of asphalt mixing station should ensure "three Jie": Clean construction site, clean living environment and clean appearance of construction products. Specific measurement, it is necessary to first 4 pieces of resistance wire strain gauge in the direction of 45° with the axis, symmetrically pasted on the stirring shaft, and make it composed of a bridge. When the shear deformation of the mixing shaft of asphalt mixing equipment occurs under the action of torque, the length and cross section of the resistance wire on the strain sheet also change accordingly. And if the amount of oil supplied is unstable, then it will also affect the level of temperature control. Although there are now some mixing equipment with automatic temperature control function, but from the temperature detection to add and subtract flame regulation temperature still need a longer process, so there will be a lag, for the asphalt mixing plant production work will still have a certain impact. It should be known that the torque size of the mixing shaft of the asphalt mixing equipment is proportional to its shear strain, so as long as the shear strain size on the outer surface of the stirring shaft is measured, the torque can be calculated, which is suitable for measuring the mixing system with large power. Therefore, reasonable control of the temperature of the mixture is one of the basic conditions that must be met in the normal production of asphalt mixing station. Among them, how the quality of the fuel will affect the temperature of the mixture. For example, if the quality of the fuel is poor, the calorific value is low, the combustion is not sufficient, then it will lead to unstable heating, low temperature, and after combustion will also produce a large number of residues, affecting the quality of the mixture. And if the viscosity is large, then it will also cause ignition difficulties, temperature is not easy to control.

installation, use and management method of large asphalt mixing station

Although the performance of the vibrating screen is intact, but because the site stone more or less will have needle flake stone existence, resulting in sieve inserts, affecting the normal screening work, so the site of the use of personnel, at any time to observe, regular cleaning of the sieve, and in strict accordance with the standard control material field stone, near may avoid the existence of needle flake stone. This can not only improve the screening efficiency and reduce the mixing rate, but also greatly improve the performance index of the finished material. In addition, also often check the drive belt tightness degree, adjust the top wire, to achieve moderate tightness, such as confirmation can not be used in time to replace. Pay attention to observe whether the lubricant level in the vibrator is suitable, if missing should be added in time, and do a regular replacement. Drying drum is a cold and wet aggregate drying heating device. In order to make cold and wet aggregate in a short period of time, to ensure that preheating, dehydration drying, heating warming three stages of orderly, required aggregate distribution in the drum, the movement of each section is reasonable, and there is sufficient running time in the cylinder to ensure that its discharge temperature to meet the requirements, but also to consider that the flame must have sufficient combustion space. Because the large Mobile Asphalt Plant mixing station is a set of perfect operating equipment, each component has the specified technical standards and application parameters, in the equipment maintenance and maintenance process, to do a good job in the collection and management of relevant information and important devices. In order to avoid material loss or other situations, to do a good job of data backup management. In addition, the daily construction machinery production and maintenance situation to do a good job of registration and registration management, all kinds of information classification management, easy to check and deal with at a later date. In the data management of the relevant staff to master Computer Management technology, asphalt mixing process involves a variety of aggregate types, the dosage and role of each data are different, in order to properly manage the data, it is necessary to take information technology as the management platform, the technical management of data, to avoid the loss of information. Like other equipment, the control system of the asphalt mixing station must be maintained on a daily basis, and the contents of the maintenance are mainly the discharge of condensate, inspection of lubricating oil and air compressor system management and maintenance. Since condensate emissions involve the entire pneumatic system, it is necessary to prevent water droplets from entering the control element. When the bucket hoist pneumatic device operation, should check whether the oil mist oil droplet is in line with the requirements, oil color is normal, must not be dust, moisture and other impurities mixed into it. The daily management of air compressor systems is nothing more than sound, temperature and lubricants to ensure that these do not exceed the prescribed standards. In the process of using heavy oil, the asphalt mixing equipment appears to burn black smoke, recycled mineral powder blackening, burning flame dimming and hot aggregate flavor phenomenon, and fuel oil consumption is large (the production of 1t finished materials need 7kg heavy oil). After the production of 3000t finished materials, the imported fuel pressure pump used in it is damaged phenomenon. Replace the new fuel high-pressure pump, keep the original circuit, pressure gauge, safety valve, stainless steel chain and other devices do not move, and set up a multi-stage filtration device on some fuel pipes to reduce impurities in heavy oil, to ensure adequate combustion. After disintegrating the fuel high pressure pump, it was found that its copper sleeve and screw were seriously damaged. Through the analysis of the structure and material of the pump, it is found that the copper sleeve and screw used in the pump are not suitable for burning heavy oil. After the imported fuel high pressure pump is replaced with the domestic fuel high pressure pump, the phenomenon of burning black smoke still exists.

In the process of controlling the circuit of the system, the signal should be shielded first and arranged according to the established requirements. In order to reduce the influence of external electromagnetic interference on the system, it is necessary to carry out hidden protection of the line, do a good job of safety protection warning, circuit direction to choose oil and high temperature areas as far as possible If in practice encountered the coordinates of the situation is not clear, to be shelved, to the final debugging process of the line for detailed inspection and analysis, in order to make up for the gap to improve it one by one, to avoid the situation of line damage.

Characteristics and function of mobile asphalt mixture mixing equipment

Asphalt mixing station as the main equipment for asphalt processing, in many engineering construction will be used, even if the performance and quality of the equipment has been a lot of improvement, but its pollution problem is still very serious. Obviously this is not in line with our environmental protection and energy saving requirements, do not know whether there is a special environment-friendly asphalt mixing station? It is obvious that the production efficiency of civil asphalt mixer is smaller, so if you want to configure asphalt mixing station, you will not choose this type of product, it is only suitable for smaller projects. The more common forms are crawl drum type asphalt mixer, diesel engine drum type asphalt mixer, climbing type asphalt mixer, lifting drum type asphalt mixer and so on. Of course, although because of more configuration, the price of environment-friendly asphalt mixing station will be higher, but still by the customer's unanimous favor, because it realizes the construction machinery also toward the direction of energy saving and environmental protection development. First to understand the structure of this environment-friendly equipment, its complexity is due to the composition of more components, including batching machine, mixer, silo, spiral pump, weighing system, electronic control system, electrical system, control room, dust collector and so on. Assemble these components into a fully sealed system so that the flow can reduce dust pollution and reduce noise emissions. The new system can ensure that the asphalt is stirred evenly, and naturally more conducive to its application. 　　The heating system of the modified asphalt mixing equipment can be modified on the basis of the original fuel burner to increase the gas function, or it can be exchanged directly for fuel, gas-use burners or gas burners. 　　1. Retrofit Burner 　　Asphalt mixing equipment used in the burner for fuel-type, not only to meet the needs of gas, but also will not affect its fuel function, the use of the original burner body, in the burner to add a low-speed cuff ring, and then equipped with a set of gas pipeline components on the line. When the fuel is removed from the low-speed cuff ring, the fuel function can be restored by using the original fuel pipeline. and engineering asphalt mixer is generally used in the mixing station to do mixing station host, because of its relatively large power, so the production efficiency is also very high, large-scale engineering construction process must choose this type of asphalt mixer. Mobile forced asphalt mixing equipment using intermittent drying cylinder, double forced mixer, the host can drag away, small footprint, short installation cycle, easy operation and maintenance, good stability, high degree of automation, high degree of standardization, and high quality products, excellence of the technology, Mobile Asphalt Plant forced asphalt Mixing station is suitable for high grade pavement asphalt laying and maintenance. How to environmental protection and emission reduction, is our current home key project, this year we will once again increase the development of asphalt mixing equipment. We strive to make our eastern asphalt mixing equipment stand out from the concept of environmental protection. The emission pollution of asphalt mixing equipment on the general market is mainly concentrated in the following aspects. To produce excellent modified emulsified asphalt products, advanced processing technology and complete sets of equipment is essential, because the modified emulsified asphalt equipment is relatively simple, and the process is also relatively simplified, so that can achieve the goal of high efficiency, energy saving, consumption reduction. 　　2. Change Burner 　　The burner can also use the direct Exchange method to achieve the purpose of oil conversion gas, asphalt mixing equipment can be based on their own actual situation to choose the burner. Asphalt mixers are used in highway construction, and if this type of equipment is differentiated according to power, there can also be differences between civil and engineering. Apart from the difference in productivity between the two, what are the differences? In the process of gradually perfecting the production equipment and gradually optimizing the production process, the production efficiency of the modified emulsified asphalt has also been greatly improved. The specific approach is to use the raw material first crushing after grinding treatment, the purpose is to the initial stirring from the swelling tank of asphalt and SBS, before entering the mill grinding cavity before pretreatment, so that it can help to reduce the energy consumption of the mill, improve the efficiency of the mill. Not only that, there are many application methods for modified emulsified asphalt, as long as the application of the appropriate method can be. and modified emulsified bitumen can be stored in storage tanks for a long time, even when used in remote areas, it is very easy to use.

A brief description of the maintenance and maintenance method of cement silo in asphalt mixing.

So far, asphalt mixing station in China has gone through a long period of development, so that, but also accumulated a wealth of production experience, technology is becoming more and more mature. In fact, we can also be very intuitive to see that the original low production efficiency has now gradually developed into a high efficiency and low energy consumption of the development characteristics. Let's take a look at the specific content together. Asphalt can be divided into three kinds of coal coke bitumen, petroleum asphalt and natural asphalt: among them, coal coke asphalt is a by-product of coking. Petroleum bitumen is the residue after distillation of crude oil. Natural bitumen is stored in the ground, some form a layer or accumulate on the surface of the crust. 1, in 60 ℃ under the viscosity of 0. >In the range of 5-10 mooring, the viscosity of the asphalt emulsion is much lower than that of the asphalt itself, so that it can be used at a lower temperature >Asphalt mixture Mixing equipment is the largest part of the investment of asphalt mixture mixing station, he not only the relationship can be normal production, but also directly determines the quality of asphalt mixture and the cost of use >Annual output of 300,000 T asphalt mixture, 2 years according to 600,000 T asphalt mixture, effective production time of 6 months per year >3 loaders are required, with a rent of 1 per flat. >50,000 yuan/month, the total cost of 540,000 yuan, the cost of electricity to each ton of asphalt mixture 3. >5 yuan/t calculation, a total of 2.1 million yuan, equipment maintenance costs of 200,000 yuan, the new equipment failure is less, mainly lubricants and some wearing parts replacement >The total operating cost of the equipment is 2.84 million yuan >Finally, the staff also need to regularly maintain the asphalt mixing station equipment maintenance management, so that the equipment is in the best working condition, daily maintenance in time to check the existence of safety hazards, and to eliminate, to ensure that the asphalt mixing station safe and efficient work >　The cost of asphalt in the total cost of asphalt mixture accounted for a larger proportion of 2000 yuan per ton of asphalt at present, equivalent to 2 yuan/kg >If the asphalt content of the mixture is 4. >8% calculation, the cost of asphalt per ton of mixture is 96 yuan >Tar-form bitumen is distilled from crude oil, which has the highest boiling point in crude oil, as well as the heaviest substance in crude oil, so it will be found at the bottom of the distillation tower >Working principle of Mobile Asphalt Plant mixing station>Asphalt, is a high viscosity organic liquid, the surface is black, soluble in carbon disulfide (a golden stench of liquid) >They are more likely to exist in the form of tar or tar >Low temperature construction and maintenance technology reduces emissions, reduces energy consumption, avoids the oxidation of bitumen, and is less harmful than the use of thermal construction technology >From the above content can be learned that the asphalt mixing station market in China has also undergone many changes, and with the development of the economy and the passage of time, the market of Vortex Air pump products is also constantly heating up >However, when we build a good station, how can we operate to ensure high productivity? Next, we will discuss this issue >In fact, there are three aspects that will have a greater impact on the production efficiency of the mixing station >The advantages of asphalt emulsion compared with thermal bitumen and cutting binder are related to low application temperature, compatibility with other water-based adhesives and other rubber latex and cement, as well as low solvent content >

Asphalt mixer is developing in the direction of environmental protection and emission reduction

　　6. Flames are not on the combustor axis. 　　If the flame is not on the combustor axis when the fuel is burning in the burner, it may be due to a change in the ring bracket or gas gun position of the gas gun, the position should be readjusted at this time.

The first is about the placement of asphalt mixing equipment, improper placement may also cause safety hazards, it is best to place the machine in a flat place, but also in its front axle wheel with sleepers fixed and overhead tires, so that the machine does not move at work. 　　3. Flames accidentally extinguished 　　If the burner flame is accidentally extinguished, it may be caused by dust from the nozzle. At this point, the nozzle can be removed for cleaning. The accidental extinguishing of the flame may also be caused by excessive or insufficient dry combustion air, at which point the blower's wind door can be adjusted appropriately to reasonably control the amount of combustion air intake. In addition, it is necessary to check whether the heavy oil temperature is too low and whether the heavy oil pressure meets the combustion requirements. If the flame can not ignite after extinguishing, may be due to excessive combustion air, at this time need to focus on checking the wind oil ratio, cam, linkage mechanism, in order to ensure a reasonable match of the wind oil ratio. As the core part of the whole asphalt mixing station, the design of the control system has been introduced to you, and then the next two are about its daily maintenance. But do not ignore this aspect, good maintenance will also be helpful to the effectiveness of the control system, thus promoting the use of Asphalt Mixing Plants mixing plant effect. Like other equipment, the control system of the asphalt mixing station must be maintained on a daily basis, and the contents of the maintenance are mainly the discharge of condensate, inspection of lubricating oil and air compressor system management and maintenance. Since condensate emissions involve the entire pneumatic system, it is necessary to prevent water droplets from entering the control element. When the pneumatic device operation, should check whether the oil mist oil droplet is in line with the requirements, oil color is normal, must not be dust, moisture and other impurities mixed into it. The daily management of air compressor systems is nothing more than sound, temperature and lubricants to ensure that these do not exceed the prescribed standards. 　　2. Burner ignition is not normal 　　The burner ignition is not normal due to the flame detector mirror stained with ash or damage. Mirror-stained ash simply wipe the detector mirror clean, and the detector is damaged, need to replace the new accessories. If the above does not solve the problem, you can try to adjust the probe direction. No matter which industry, if you want to have prospects for development, you must not be free from the concept of environmental protection, our asphalt mixing equipment industry is the same. Asphalt concrete Mixing station belongs to the production equipment of large-scale road construction materials, which is one of the indispensable important equipment for building maintenance and construction, and the proportion of investment in the construction and maintenance of roads is large. How to environmental protection and emission reduction, is our current home key project, this year we will once again increase the development of asphalt mixing equipment. We strive to make our eastern asphalt mixing equipment stand out from the concept of environmental protection. The emission pollution of asphalt mixing equipment on the general market is mainly concentrated in the following aspects. In addition, the ability to effectively control the resulting pollutants, can reduce the production process of pollutants produced by the direct damage to the environment, is qualified to be defined as an environmentally friendly asphalt concrete mixing station. There is also the requirements of its factory land planning, whether it is the production area or waste water waste gas conversion zone, should be reasonable.

　　Drilling degree directly ringing oil pump, injector efficiency and fuel consumption, the greater the drilling, the worse the atomization effect, so should choose moderate drilling of heavy oil. Sulphides in heavy oil can lead to corrosion of burners, drying rollers, airway and dust collectors, so heavy oil with less sulfur content should be selected, and the general sulfur content should be controlled at 0. 5% or less. The moisture content contained in heavy oil will not only reduce the content of combustible components in fuel, make the fuel ignition difficult, but also increase the corrosion of pipes and equipment, enhance the heat loss of exhaust smoke and transport energy consumption, and if the uneven amount of moisture may directly lead to flame pulsation or even quenching, so should choose water content less than 1% of heavy oil. Mechanical impurities in heavy oil will clog the filter, injector, valve core, speed up oil pump wear, so should choose mechanical impurity content less than 0. 5% of the heavy oil.

Location of mobile Asphalt mixing station

Before the asphalt pavement is applied to the surface (especially if it is an existing asphalt surface), the asphalt pavement should first be prepared by spraying a thin liquid asphalt binder (thermal binder) with an asphalt distributor. 　　3, asphalt mixer layout According to the pile floor layout map, the error must not be greater than 2CM. Configuration of 110KVA construction electricity and f25mm water pipes, placement of double-axis mixing machinery and equipment and auxiliary slurry mixing equipment, conveyor lines, strictly ensure the vertical degree of the mixer Guide frame. 　　2, asphalt mixer construction process Measurement of the layout of the site is flat, groove excavation of the in-depth mixer in place of the "the pre-stirring sinking of the grouting slurry preparation of the Pipeline cleaning of the the machine shift. The main feature of portable asphalt mixing equipment is that it is installed on a flat trailer, which can be transported to different construction sites and then put into use after a simple and quick installation. 1, asphalt mixer construction, should first asphalt mixer construction range of the top miscellaneous filling soil removal, and should maintain a dry, flat site elevation to meet the design requirements, the surface is too soft, to strengthen the foundation, prevent construction machinery instability, to ensure that the pile frame vertical, inbound construction machinery to check, to ensure that the machine intact, assembly and commissioning, To ensure the verticality of the mixer, the deviation of the gantry guide and the mixing shaft from the ground verticality must not exceed 1. 0%. The second is the asphalt mixing station commutator valve will encounter some problems. The main problems that may arise include: 1, can not be commutative or the commutative action is slow, 2, the valve core seal ring damage is serious, 3, the pilot solenoid valve stomata is blocked, can not be commutative and so on. In response to these problems, we not only need to carry out regular inspections, but also to maintain a good degree of cleanliness. In addition, damaged parts should be replaced in a timely manner to reduce the probability of problems occurring. 3rd, the selected location should have sufficient space for construction operations. Although the Mobile Asphalt Mixing Plant asphalt mixing station is relatively space-saving, it still requires that the site can provide sufficient space for mixing building placement, storage and driving operation, and to ensure better geological conditions, site formation and so on. 　　　　 　　When the stirring shaft sinks to the design depth, it begins with 0. 45~0. 8m/min Speed Drill grouting. The slurry should be prepared and placed in the set hopper before lifting. After the grouting is stirred to the ground, it sinks and mixes again, so that the soil and the slurry are fully blended. The third is the possible failure of the cylinder in the asphalt mixing station. The main problems that may arise include: 1, internal and external leakage of cylinders, 2, insufficient output force and uneven movement, 3, poor cushioning effect, 4, piston rod and cylinder head damage and so on are included. For these problems, for reasons that vary, we need to identify the causes and take targeted measures to deal with them. Compared to other portable asphalt equipment manufacturers, our company's innovative sale of portable asphalt equipment has the greatest flexibility, reasonable price, high reliability and high availability and other advantages. In general, for the location of mobile asphalt mixing stations, we must fully consider in advance, we must ensure that the location of the site will not adversely affect the surrounding residents and the environment. In addition, the issue of economic reasonableness needs to be taken into account. Only in this way, we can ensure that our location is reasonable, the following to see the specific content. 1th, the location of the selected mobile asphalt mixing station should be kept within a reasonable range from the construction site. In general, we consider that it is best to choose such a location, both near the midpoint of the construction standard, and the transport conditions are convenient, can save the cost of transportation of finished materials. In addition, the sources of water and electricity are also more convenient. From the beginning, our company has professional sales staff who will provide you with the best advice for the sales selection and management of your construction projects as a portable asphalt mixture mass production plant. Therefore, we mainly share today on the asphalt mixing station Air road system is relatively easy to appear some of the fault phenomenon, I hope to help you. The first is the fault of the gas source, in fact, the so-called gas source failure includes many kinds, and many parts may have this problem. For example, in the case of air compressor, there may be the problem of slow pressure rise, as for the pipeline, may also be due to joint leakage and hose rupture caused by leakage and so on.

Operation key points of weighing control system for asphalt mixing station

During the feeding period should also be carried out in accordance with the provisions, for example, when using forklifts, must observe the car before and after the personnel, in the cold hopper on the material must pay attention to speed and position, can not collide with the asphalt mixing station equipment. The last way is called lightning protection grounding, if subdivided, it can also be divided into two ways, the specific content is: 1, for the laying of signal lines metal cable pipe or groove surface grounding, can prevent coupling interference; 2, if the asphalt mixing station control system is overhead signal line, need to take lightning protection measures at the computer input terminal, Inhibits interference. When you start working, you should be prepared. When everything is ready, when you are ready to start the machine, you should honk the horn to remind the people around you, make sure that the surrounding environment is safe before you can start the machine. When producing loading, be sure to keep an eye on the location of the vehicle to ensure safety. Asphalt mixing station Machine during operation, staff are required not to carry out the maintenance of equipment at will, only in the premise of ensuring safety, can carry out maintenance work, and must inform the control room operators in advance, control room operators have to agree with the outside personnel before restarting the machine. The first step is to develop a reasonable, detailed and practical demolition plan. In the process of making the plan, it is necessary to take into account the consideration of various factors, combined with the characteristics of the whole mobile Asphalt Drum Mix Plant mixing station, according to the predetermined requirements to demolish the mixing building, and in accordance with the appropriate disassembly sequence. The second step, select the appropriate disassembly team. We need to remind you that the technical level of the disassembly team will seriously affect the disassembly of the mixing building. 　　 The second way is the power supply system grounding, this grounding method still has a lot of benefits. In the basic installation, the manufacturer will first prepare a foundation map, and then according to the requirements of this diagram layout of a large ground network, most of the time, the entire asphalt mixing station control system is connected with this ground network, is not directly using the power system of the ground line. If abnormal conditions occur when the ingredients are found, the operator should immediately press the "EMER Stop" (Emergency stop) button to forcibly close all incoming silo doors. To ensure that the door control button on the operating table function is intact, as long as the operator tap, the corresponding warehouse door should be opened. However, in the interlock state, if the metering warehouse door is not closed, the feed warehouse goalkeeper can not open, if the mixing cylinder discharge door is not closed, each metering warehouse goalkeeper can not open. If there is an abnormality in the system software during the batching process, the operator has 2 ways to restart: First, turn off the system power and reopen the system, and second, click the "Emergency Reset" button to restore the system to normal. When we need to form a mobile asphalt mixing station that meets the requirements of use, if some of the early preparation and planning work has been done, then the next step is the need to demolish the asphalt mixing building. Usually, in the process of setting up mobile asphalt mixing station, the demolition speed of asphalt mixing building is the key factor to determine the whole work progress. Finally, the safety of the whole construction process should be guaranteed to ensure that there are no personnel damage during the construction period, and no equipment damage. In this way, a qualified mobile asphalt mixing station can eventually be formed. Be sure to pay attention to all the dangers and pitfalls of precautionary, and require staff to ban smoking within three meters of diesel cans and heavy wood cans, not to have open fires, and not to let oil out when unloading oil. Asphalt mixing station in the process of unloading asphalt, we must first determine the amount of asphalt in the tank, the valve opened before the asphalt can be unloaded, absolutely not allowed to smoke on the asphalt tank. Therefore, as a production enterprise, whether from the economic point of view, or from the progress of the work and other aspects to consider, are hoping to be able to complete the demolition of the mixing building in a reasonable way. Only in this way can we ensure the smooth operation of the mobile asphalt mixing station. In the mixing building demolition, we mainly need to do a good job in four aspects of the work. The details are as follows:　 In carrying out maintenance work, the staff should pay attention to their own personal safety and be sure to fasten their seat belts when working in high places. When someone is working inside the machine, it is necessary to arrange for personnel to look after the outside, while the asphalt mixing station power supply should be closed, without permission, the control room operators may not open without permission.
