The importance of asphalt mixing equipment in road construction
It is undeniable that road construction has promoted the development of asphalt mixing equipment. As the saying goes, if you want to get rich, you must first build a road. It could be seen that road construction plays an important role in economic development. Therefore, with the rapid development of road construction, the demand for asphalt mixing equipment is also increasing. Traditional asphalt mixing equipment can no longer meet modern development requirements. Therefore, the asphalt mixing equipment has been upgraded and optimized according to construction requirements.
Asphalt mixing equipment is a kind of ordinary road construction machinery widely used in the construction of urban and rural roads, parking lots, highways, airports, ports and other roads. Continuously optimized asphalt mixing equipment can meet the different needs of various sites.
Features of asphalt mixing equipment:
1. The asphalt mixing equipment is equipped with an automatic fault diagnosis device, which can reduce the failure rate and reduce maintenance costs.
2. Adopting frequency conversion speed regulation device can automatically control and effectively adjust the processing speed.
3. The compact and reasonable layout of the asphalt mixing equipment is convenient for quick disassembly.
4. Asphalt mixing equipment adopts advanced PLC programmable electrical control system. The entire operation can be operated with simple finger touch buttons. High automation system can save a lot of time, manpower and cost, and can greatly improve work efficiency.
5. The data (bitumen composition formula, historical production records, etc.) can be saved through the safety protection device. Safety protection will be activated automatically in an emergency.
6. The aggregate and asphalt have a secondary metering device, which can ensure the accuracy of weighing and mixing, and produce high-quality asphalt mixtures.
7. Use high anti-fatigue and heat-resistant materials to extend the service life of each component.
8. The double-row chain plate aggregate lifting system has a return device to avoid aggregate backflow. In addition, the lifting system ensures more stable operation.
Today, common asphalt mixing equipment is mainly divided into five series: double drum series. Due to the low gradation, the utilization rate is not high, which is more suitable for projects that do not require high road quality; QLB-Y series asphalt mixing station, full mobile (Convenient for transfer); QLB-X series asphalt mixing station(, ready silo bottom-mounted with advantage of saving space and power; side type QLB series asphalt mixing station of finished products (most popular, moreover, due to cost considerations, ready silo could be saved or as an option).
The final type-green series, is the latest environmentally-friendly asphalt mixing Equipment, also known as a new type of urban green environmental protection equipment. Due to a series of factors such as China's domestic population, environmental pollution, economic development, and policy orientation, China's domestically-made environmentally-friendly equipment has taken the lead in the world.
The latter four series have the advantages of the first gravity dust removal plus the second baghouse dust collector system and the main building's negative pressure dust control design.
transform the heating system of asphalt mixing equipment
The modification of heating system of the asphalt mixing plant could be processed on the basis of the original fuel burner to increase the gas/LPG function, or it can be directly replaced by an oil-gas-combination burner or a gas burner.
Asphalt mixing station is a relatively important equipment in highway construction during its use. In production, whether its electrical system works reliably, largely determines whether the asphalt concrete mixing station could be normally produced and whether road works could be completed as scheduled.
The installation of the asphalt mixing station from a large perspective, the content mainly includes foundation production, mechanical metal installation, electrical system installation and commissioning, asphalt heating and pipeline installation. The mechanical metal structure can be installed in one step under the condition that the asphalt station foundation is constructed, and it is rarely adjusted and changed in future production. Asphalt heating and pipeline installation are mainly for asphalt heating services, and the installation workload mainly depends on the equipment that stores and heats the asphalt.
Familiar with the system, wire reasonably
According to the drawings and the installation position of the electrical components, the wiring is concentrated from the peripheral part to the control units or the control room one by one. The cable should be arranged in a suitable path, and the weak electric cables and the strong electric signal cables must be arranged separately.
The electrical system of the asphalt mixing station includes strong current, weak current, AC, DC, digital signals, and analog signals. In order to ensure that these electrical signals could be effectively and reliably transmitted, each control unit or electrical component could output the correct control signal in time. And could reliably drive the various actuators, the reliability of the electrical circuit connection must be of high reliability. Therefore, during the installation process, it is necessary to ensure that the connections at various wiring points are reliable and the electrical components are correctly and properly installed and fastened.
The main control units of the asphalt mixing station generally adopt industrial control computers（IPC） or PLC (programmable logic controllers). Their control process is generally based on that as soon as the internal circuits detect the electrical input signals that meet a certain logical relationship, it will output electrical signal in accordance with a certain logic in time, to drive relays or other electrical units or components. The work of these relatively precise components is generally relatively reliable. If there is a failure during operation or trial running, first check whether the relevant input signals are all in place, and then check whether the required output signals are available and whether they are output in accordance with certain logic requirements.
In general, as long as the input signal is valid and reliable and meets the logic requirements, the output signal will be output according to the internal program design requirements, unless the wiring head (wiring board) is loose or the peripheral components and wiring related to these control units are faulty. Of course, in some special cases, internal components of the unit may be damaged or a certain circuit board may fail.
