Analysis of the structural principle and advantages of asphalt tanks Asphalt tanks are internal heating type partial rapid asphalt storage heater equipment. The series is currently the most advanced asphalt equipment in China that integrates rapid heating, energy saving and environmental protection. The direct heating portable equipment in the product not only has a fast heating speed and saves fuel, but also does not pollute the environment. It is easy to operate and the active preheating system completely eliminates the trouble of baking or cleaning asphalt and pipelines.

In order to meet the development needs of domestic infrastructure, the market demand for asphalt mixing plants is becoming larger and larger, and more and more people will invest in them. In this process, the site selection issue is very critical, and it is directly related to the long-term operation of the mixing station in the later stage. Regarding the site selection of asphalt mixing plants, experts have put forward three principles, and I hope everyone can keep them in mind.

Asphalt mixing plant equipment can produce asphalt mixture, modified asphalt mixture, and colored asphalt mixture, which fully meet the needs of building highways, grade highways, municipal roads, airports, ports, etc. Because of its perfect structure, correct grading, high metering accuracy, good quality of finished materials, and easy control, it is widely welcomed in asphalt pavement projects, especially highway projects, but sometimes tripping occurs during work, so what should we do when this phenomenon occurs?

With the development trend of scientific and technological innovation, the emergence of bitumen de-barreling equipment has brought great convenience to our work and has been widely used in every place. What difficulties must be paid attention to when feeding bitumen de-barreling equipment? The grinding wheel of the bitumen de-barreling equipment of the bitumen de-barreling equipment has no heating barrel clamp. Before use, try to add a small amount of diesel engine, let the bitumen de-barreling equipment circulate for 3~5 minutes, so that the body will generate heat. The temperature of the bitumen de-barreling equipment after operation is about 80~100 degrees. Open the stop valve on the oil pipeline, move it to open and close it, and discharge the whole body diesel engine.

The viscosity of emulsified bitumen equipment decreases with the increase of temperature during the production process. The power viscosity of emulsified bitumen equipment is about twice as high as every 12℃ increase. During processing, the culture medium bitumen barrel should be heated to liquid before demulsification. In order to better integrate the demulsification emulsified bitumen equipment capacity of the colloid solution mill, the culture medium bitumen barrel power viscosity is generally controlled to be about 200cst. The lower the temperature, the higher the viscosity, which increases the pressure of the bitumen barrel pump and the colloid solution mill, and the emulsion cannot be demulsified. However, on the other hand, in order to prevent the emulsified bitumen equipment from weaning when the finished product water evaporates, it is unlikely to overheat the culture medium bitumen barrel temperature. Generally, the finished product temperature at the inlet and outlet of the colloid solution mill should be less than 85℃.

Before starting the control system of the asphalt mixing plant equipments, the following eight aspects should be considered: Is the limit switch normal? Is there any alarm appearing on the operating interface of the computer? Start the oblique belt and flat belt; Start the mixer; Start the mixing plant source air compressor pressure after 0.7MPa pressure to meet the surrounding pressure; Disable the automatic production of concrete switch, "prohibit concrete" file; Switch the operating table of the concrete mixing station control system from "manual" to "automatic"; Then turn on the emergency stop button switch, and then manually control the console power supply, PLC and instrument power supply display normal, open UPS, and turn on the computer for inspection.
