What should I do when the reversing valve in the asphalt mixing plant fails? The editor has a trick:
1. The reversing valve cannot be reversed or the reversing action is slow, which is generally caused by poor lubrication, stuck or damaged springs, oil or impurities stuck in the sliding parts. In this regard, you should first check whether the oil mist is working normally; whether the viscosity of the lubricating oil is appropriate. If necessary, the lubricating oil should be replaced, the sliding part of the reversing valve should be cleaned, or the spring and reversing valve should be replaced.

During the use of emulsified bitumen equipments, if maintenance is not paid attention to, the cycle will be short, and problems will often occur during use. Only by doing a good job of maintenance can the operation efficiency of the equipment be improved. For example, during maintenance, the following points must be grasped.
It is necessary to regularly check the wear condition of the internal structural components of the mechanical equipment, such as the core feed pipe, the rough jaw plate on the impeller, the cone cap, the wear level of the jaw plate, the rain shield on the circle, and the wear condition. If the wear is more serious, it is necessary to replace or repair it in time. When replacing, it is also necessary to pay attention to the model and specifications, and replace it according to the original components as a reference.

The application of asphalt mixing plants also involves selection issues. In order to give full play to the performance of the equipment, the model of the machine is mainly determined according to the actual situation of the construction site. It sounds relatively simple, but some details still need to be emphasized.
The so-called specific conditions of the construction site first include the size of the site; secondly, the properties, specifications and working dimensions of the enterprise’s supporting equipment. It is necessary to try to do a good job in all aspects to help improve production efficiency and ensure product quality. In the case of intensive network management, the network management function of the asphalt mixing plant must also be taken into account to avoid difficulties in future upgrades.

Asphalt spreader vehicle is an intelligent and automated high-tech product that specializes in spreading emulsified asphalt, diluted asphalt, hot asphalt, high-viscosity modified asphalt, etc.
Asphalt spreader is used for spreading the penetration oil, waterproof layer, and bonding layer of the bottom layer of the asphalt pavement of high-grade highways. The spreader consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, an ignition system, a control system, a pneumatic system, and an operating platform.
Asphalt spreader is cumbersome to operate. On the basis of absorbing various technologies of similar products at home and abroad, it increases the quality technology content of construction and the humanized design of outstanding improvement of construction conditions and construction environment. Its reasonable and reliable design ensures the uniformity of asphalt spreading, the computer control is stable and reliable, and the technical performance of the whole vehicle has reached an advanced level.

Asphalt is commonly used in our modern urban life, especially in the process of urban highway construction. As an important road surface paving material, the demand for its use is relatively high. Only by using better relevant material performance characteristics can the overall effect be well helped.
Asphalt mixing plants are equipment products that need to be involved in the production and use of such products. With its own excellent performance, it has been better expanded in the promotion of the existing market use scope. The coordination of external use factors is also a key part, and the relationship between various factors must be handled well.

The heating principle of asphalt decanter equipment is to heat, melt and decanter the asphalt through the heating plate. It is mainly composed of de-barreling box, lifting system, propeller and electrical control system.
The box of asphalt decanter plant is divided into upper and lower chambers. The upper chamber is the asphalt melting chamber, which is densely covered with heat transfer oil heating coils or hot air heating pipes. The asphalt is melted and removed from the barrel by heat. The hoisting hook is installed on the gantry, and a barrel grabber is hung. The asphalt barrel is lifted by the electric winch, and then the asphalt barrel is placed on the guide rail by horizontal movement. Then the propeller pushes the barrel into the upper chamber through two guide rails, and an empty barrel is pushed out at the rear end outlet.
An anti-drip oil tank is provided at the entrance of the asphalt barrel. The asphalt enters the lower chamber of the box and is continuously heated to a temperature of about 100 to be transported, and then pumped into the asphalt tank by the asphalt pump. The lower chamber can also be used as an asphalt heating tank.
The asphalt decanter plant has the characteristics of not being restricted by the construction environment, strong adaptability and extremely low failure rate. If large production is required, multiple units can be assembled.

In order to keep the asphalt mixing plant in a stable operating process, a series of adverse factors related to it must be excluded. What should be paid attention to in this process?
First of all, the selection of the delivery pump in the asphalt mixing plant must meet the requirements of asphalt pouring per unit time during construction, height, and horizontal distance requirements. At the same time, there must be a certain technical and production capacity reserve, and the balanced production capacity is preferably 1.2 to 1.5 times.
Secondly, the movement and hydraulic systems of the asphalt mixing plant must be normal, and there must be no abnormal sound and vibration to avoid large aggregates and lumps inside the equipment, otherwise it is easy to get stuck at the feed inlet of the mixing plant or be blocked due to arching. Another point is that when the asphalt mixing plant is in the same site, it is not suitable to use too many pumps and pumps from multiple manufacturers to avoid affecting its normal operation.

Asphalt melting equipment follows the continuous development of urbanization. Whether in rural areas or in big cities, you can see a lot of construction sites, among which it is inevitable that asphalt melting equipment is set up nearby. Asphalt melting equipment manufacturers, whether large or small asphalt melting equipment or relatively large and small, although it is just a simple mechanical equipment, but to move or transport it, it is a small matter, and there are many places that require attention.
The technical level of the asphalt melting equipment disassembly and assembly team directly affects the disassembly and assembly progress of the asphalt melting equipment; improve on-site supervision, reasonably organize disassembly and assembly machinery and equipment and workers, try to avoid cross-operation, and promote the disassembly and assembly process to consume less manpower and machinery shifts to do a good job in the transportation of asphalt melting equipment; ensure that the asphalt melting equipment is not damaged and the prefabricated components are not missed.

In addition to being used according to regulations, modified bitumen equipment should also be maintained regularly in order to effectively extend the service life of modified bitumen equipment. The delivery pump of modified bitumen equipment, as well as its motor and reducer, need to be maintained in accordance with the specifications of the instructions. If the modified bitumen equipment is parked for a long time, the liquid in the tank and pipeline needs to be drained, and each moving component also needs to be filled with grease. The dust in the control box of the modified bitumen equipment needs to be cleaned once every six months. A dust blower can be used to remove dust to prevent dust from entering the machine and damaging parts. The micro powder machine needs to add unsalted butter once for every 100 tons of emulsified bitumen produced.

The plug valve is a rotary valve in the shape of a closure or plunger. After rotating 90 degrees, the channel opening on the valve plug is the same as or separated from the channel opening on the valve body to complete opening or closing. It is widely used in oilfield excavation, transportation and refining equipment, and such valves are also needed in asphalt mixing plants.
The valve plug of the plug valve in the asphalt mixing plant can be cylindrical or conical. In the cylindrical valve plug, the channel is generally rectangular; in the conical valve plug, the channel is trapezoidal. These shapes make the structure of the plug valve light and very suitable for blocking and connecting media and diversion.

Except for the first application, for enterprises whose block asphalt melting equipment license has expired and continue to engage in the production and operation of block asphalt melting equipment, they should apply for the relevant matters of postponement and renewal 45 working days before the expiration of the license.
The block asphalt melting equipment should first prepare the block asphalt melting equipment application materials, and then submit an application for postponement and renewal to the municipal environmental protection bureau. According to the production and operation of the block asphalt melting equipment and environmental protection work of the applicant enterprise, the municipal environmental protection bureau of the district where the block asphalt melting equipment is located will provide a review opinion in the form of a public document.

Emulsified modified asphalt equipment is classified according to the production process and can be divided into three types: intermittent emulsified modified asphalt equipment, semi-continuous emulsified modified asphalt equipment, and continuous emulsified modified asphalt equipment. During the production of emulsified modified asphalt equipment, demulsifier, acid, water, and latex modified materials are blended in a soap mixing tank, and then pumped into the asphalt into the colloid mill. After a can of soap is used up, the soap is redispensed, and then the production of the next can is completed.
The emulsified modified asphalt equipment mentioned here includes hot water pumps and circulation pumps. This type of centrifugal water pump generally uses a pipeline centrifugal pump. There is a sewage outlet at the bottom of the pipeline centrifugal pump. Pay attention to the sewage outlet at the bottom of the emulsified modified asphalt equipment pump. The water in the water tank is released through the filter valve. Some emulsified modified asphalt equipment does not have a filter valve to save equipment costs, so it can only be emptied by loosening the flange bolts at the bottom. There are basically two methods of moisturizing emulsion pumps for emulsified modified asphalt equipment on the market, gear oil pumps or centrifugal water pumps. The gear oil pump can only drain the liquid in the pump through the connecting flange of the pipeline. The centrifugal water pump carries out sewage treatment through its own sewage outlet.
When used in the production of emulsified modified asphalt equipment, depending on the modified material technology, the latex pipeline can be connected in front of the colloid mill or behind the colloid mill, or there may be no latex pipeline and it must be made manually. Add the required amount of latex into the soap jar.

Judging from the situation of highways in our country, asphalt pavement is the most used, which is one of the reasons why asphalt mixing plants have developed so rapidly. Under the situation of rapid economic development, the quality problems of asphalt pavement are gradually increasing, which puts forward higher and higher requirements for the quality of asphalt. It is understood that the primary factor that affects the quality of asphalt is the ratio of raw materials. This is also covered in the introduction of asphalt mixing stations. You can discuss it together.
In order to obtain high-quality asphalt products, in addition to the asphalt mixing equipment meeting the requirements, selecting the appropriate asphalt mixture gradation type is also a top priority. According to my country’s current regulations, the maximum particle size of the asphalt mixture in the upper layer of the highway should not exceed half of the layer thickness; while the maximum particle size of the aggregate in the middle surface layer of asphalt mixture should not exceed two-thirds of the layer thickness; and the asphalt layer should not exceed half of the layer thickness. The maximum nominal aggregate size of the pavement structural layer mixture should not exceed one-third of the layer thickness.
Based on this analysis, if an asphalt surface layer with a certain thickness is selected according to the above specifications, the particle size of the asphalt mixture aggregates will generally be larger, which will inevitably bring insurmountable construction difficulties to the construction of asphalt concrete pavement. After investigation, testing, analysis, and comparison, it can be seen that the lower layer has a wider choice, so the AG-201 gradation type can be used; while the selection of the upper layer mixture type is more difficult, and it is necessary to achieve a reasonable choice of this mix ratio. , on the one hand, we must examine as many aggregate resources as possible, and on the other hand, we must also consider the model of the mixing equipment.
In order to ensure the quality of the project, strict selection and inspection of engineering materials must be carried out. Therefore, the selection and determination of raw materials should be based on the requirements for pavement structure and use quality, combined with the supply of floor materials, and inspection in accordance with the requirements of relevant test procedures, and then Select the best materials so that all technical indicators of the materials meet the specified technical requirements.

Asphalt concrete mixing equipment generally uses conveyor belt conveyors to transport cold materials. Its main advantages are large conveying capacity, continuous operation, simple equipment structure and automatic control. However, belt deviation is a common fault, which directly affects the drying operation of the drying drum and also affects the production efficiency of the mixing equipment. Therefore, it is very important for the asphalt mixing station to solve the belt deviation problem at the operation site of the asphalt concrete mixing equipment.

Except for the first application, for enterprises whose block asphalt melting equipment license has expired and continue to engage in the production and operation of block asphalt melting equipment, they should apply for the relevant matters of postponement and renewal 45 working days before the expiration of the license.
The block asphalt melting equipment should first prepare the block asphalt melting equipment application materials, and then submit an application for postponement and renewal to the municipal environmental protection bureau. According to the production and operation of the block asphalt melting equipment and environmental protection work of the applicant enterprise, the municipal environmental protection bureau of the district where the block asphalt melting equipment is located will provide a review opinion in the form of a public document.

After the rubber bitumen storage tank is cleaned, the wood chips are sent to the rubber bitumen storage tank, and the wood chips and the bottom of the rubber bitumen storage tank are wiped with wood chips. The dirt and wood chips in the bitumen tank can be weathered naturally. The rubber bitumen storage tank is not allowed to be damaged. Check the technical specifications of the underwater concrete processing equipment and ventilation equipment.
The bottom of the rubber bitumen storage tank drain pipe is discharged from the drainage pipe, and the waste water is discharged into the empty tank or other containers through the inlet and outlet and the self-draining pipe. Open the Shenzhen manhole into the plastic suction pipe and pave the Shenzhen manhole with asbestos to reduce the discharge of oil and gas. When manually pumping the bottom oil, two people should be operated to improve the labor efficiency of the workers and send the fuel tank to supervision.

With the strengthening of the trend of environmental protection and energy conservation, the environmental protection of asphalt mixing plants has gradually become the mainstream form of mixing plant development. What kind of equipment can be called an environmentally friendly asphalt mixing plant? What are the basic conditions that must be met?
First of all, as an environmentally friendly asphalt mixing plant, it must meet the requirement of using less energy consumption during use. That is to say, under the conditions of the same quantity and quality, less energy is consumed during the operation process, including various resources such as water and electricity.
Secondly, environmentally friendly asphalt mixing plants not only require less energy consumption, but also must achieve higher production efficiency, while also reducing carbon emissions in the entire production process, so as to meet the proposed low-carbon production requirements

Regarding the basic knowledge of modified bitumen plant, I believe that many consumers have already had a basic understanding of it. Because of the continuous development of various fields today, various facilities including modified bitumen plants have been well developed and applied, and modified bitumen plant has gradually been recognized by customers.
The direct quick heating portable equipment in the modified bitumen equipment not only has a faster heating speed, saves fuel, and is pollution-free, but also convenient and easy to operate. The automatic heating system completely eliminates the trouble of baking or cleaning bitumen and pipelines.

Speaking of asphalt mixing plants, we are not unfamiliar with them. This is a unit equipment specially used for asphalt mixing. In fact, what we really lack understanding of is its gas system. Even the accumulated failures that often occur in the gas system of asphalt mixing plants are not very clear. Facts have proved that only by properly maintaining the various systems of the equipment can efficient production and good benefits be achieved.
The following are four types of gas system failures that often occur in asphalt mixing plants. Let’s analyze the causes of the problems behind the failures one by one.

Water is one of the raw materials of the modified asphalt storage tank, and it is distributed in various components of the modified asphalt storage tank equipment. According to the components where water is distributed, the anti-cold measures are explained one by one. The water tank of the modified asphalt storage tank, the water inside the water tank is released through the filter valve. Some instruments of the modified asphalt storage tank do not have a filter valve to save the cost of the equipment. The modified asphalt storage tank can only be drained by loosening the flange bolts at the bottom. The water pump of the modified asphalt storage tank mentioned here includes a hot water pump and a circulating water pump. This type of water pump for the modified asphalt storage tank generally uses a pipeline centrifugal pump. There is a sewage outlet at the bottom of the pipeline centrifugal pump. The modified asphalt storage tank pays attention to the sewage treatment of the sewage outlet at the bottom of the pump. The modified asphalt storage tank emulsion tank generally uses a cone bottom. However, in order to better process the modified asphalt storage tank coefficient, the inlet and outlet are usually not placed at the bottom of the modified asphalt storage tank. Emulsion (mostly water) will remain at the bottom of the tank, and this part of the residual liquid in the modified asphalt storage tank must be discharged through the filter valve at the bottom. Emulsion pump for modified asphalt storage tank There are basically two types of emulsion pumps for modified asphalt storage tank equipment on the market, gear pumps or centrifugal water pumps. Gear pumps can only discharge the liquid inside the pump through the connection flange of the pipeline. The centrifugal water pump for modified asphalt storage tanks uses its own sewage outlet for sewage treatment. The first four items of modified asphalt storage tanks with basic knowledge are basically discharged, and the modified asphalt storage tanks will focus on the latter types. Modified asphalt storage tank colloid mill There will also be residual emulsion or water inside the modified asphalt storage tank colloid mill. The gap between the stator and rotor of the colloid mill is within 1mm. If there is a little residual water in the modified asphalt storage tank, it will cause the accident of frozen modified asphalt storage tank. The residue in the colloid mill can be treated by loosening the connection bolts of the finished product pipeline.

According to the configuration, layout and controllability of bitumen melting equipment, bitumen melting plant can be divided into three types: mobile, transportable and portable. What should be paid attention to in the production of bitumen melter equipment of different sizes? Let’s learn about it below!
Bitumen melting plant is to fix the demulsifier mixing equipment, black anti-static tweezers, asphalt pump, automatic control system, etc. on a special support chassis. Because the bitumen melter equipment can directly change the production site, it is suitable for the production of emulsion bitumen in construction sites with decentralized projects, small usage and frequent movement.
The main components of the bitumen melting equipments are installed in one or two 60 standard containers. The bitumen melting plant is loaded and transported separately to complete the relocation of the construction site. With the help of asphalt melting equipments hoisting equipment, it is quickly installed and put into operation. Such bitumen melter plant has large, medium and small different configurations, which can meet different project requirements.

Standard five-layer calcination is made by stacking and vacuum calcining five layers of stainless steel barrel removal wire mesh. The stainless steel barrel made of it has corrosion resistance, good water permeability, high compressive strength, easy cleaning and back-cleaning, high filtration precision, hygienic and clean filter material, and stainless steel barrel removal wire mesh does not fall off.
Double-layer metal sintered mesh is a new type of filtration system with high impact toughness and overall rigidity, which is made by stacking and vacuum calcining double-layer stainless steel barrel removal wire mesh products.

Many people think that since both asphalt mixing plants and asphalt mixing plants are equipment for producing asphalt, there should be no difference between them, even if there is, it is only in appearance and volume. However, asphalt mixing plants and asphalt mixing plants are different in even their basic structure and function.
First, let me introduce the basic structure of an asphalt mixing plant, which includes five major components: material supply system, metering system, mixing system, and electrical control system. In comparison, the structure of an asphalt mixing plant is simpler, without so many components, so its operation and maintenance will be simpler.

The difficulty of emulsified bitumen equipment itself, because general bitumen also has different classifications, in the production and processing of emulsified bitumen equipment bitumen concrete, it is necessary to pay attention to whether the common raw materials are the common bitumen and ensure the quality. Check the black antistatic tweezers of emulsified bitumen equipment asphalt concrete machine equipment emulsified bitumen equipment.
If the gap of the black antistatic medical tweezers bitumen concrete micro-powder machine of emulsified bitumen equipment is enlarged after long-term use, then we can adjust it and continue to process it. Emulsified bitumen equipment is a relatively simple difficulty.

Due to raw materials or usage, asphalt mixing plants will be subject to a certain degree of wear or other failures during daily use. If they are not controlled or repaired in time, the problem will be further exacerbated. For asphalt mixing plants, what are the ways to prevent wear and failure?
If the asphalt mixing plant is not treated in time after being worn, it may corrode once it is in contact with air, rainwater, etc. for a long time. If the parts of the asphalt mixing plant are severely corroded, the service life and normal operation of the entire equipment will be affected.
