The thermal oil asphalt tank is equipped with heating pipes. Pour high-temperature heat transfer oil into the heating coil. Under the action of the hot oil pump, the heat transfer oil is forced to circulate in a closed circuit within the heat transfer oil pipeline system. The heat transfer oil carrying high temperature is transported to the thermal equipment, and the heat energy is transferred to the low-temperature asphalt, thereby increasing the temperature of the asphalt. After heat dissipation and cooling, the heat transfer oil returns to the heating furnace for reheating and cycle heating.

In the asphalt mixing process, heating is one of the indispensable links, so the asphalt mixing station must be equipped with a heating system. However, since this system will malfunction under the influence of various factors, it is necessary to modify the heating system to solve hidden problems to reduce such situations.
First of all, let’s first understand why heating is needed, that is, what is the purpose of heating. We found that when the asphalt mixing station is operated at low temperatures, the asphalt circulation pump and spray pump cannot operate, causing the asphalt in the asphalt scale to solidify, which ultimately leads to the inability of the asphalt mixing plant to produce normally, thus affecting the Quality of construction work.

Due to its complexity and importance, asphalt mixing stations are more critical in road construction. Modern asphalt mixing stations have five key systems. Do you know what they are?
1. Mixing system of asphalt mixing plant
Mixing equipment is one of the key systems, why? Usually, the productivity of the mixing equipment has a great influence on the efficiency of the next step of construction. Most asphalt mixing plants use twin-shaft forced mixing. Because the drying drum and burner of the mixing equipment have strong overload capabilities, and in most cases, the moisture content of the mineral materials is less than 5%, which improves the productivity of the mixing equipment. provide conditions. The mixing blades of the mixer have an adjustable assembly angle and are driven by dual mixing shafts and dual motors.

Highway construction plays an active role in economic development and construction. Over the past few decades, various highway construction projects have continued to achieve new results. Correspondingly, construction requirements for road construction machinery and equipment are also more complex. To prevent accidents from occurring during mechanized construction and ensure the safety of equipment and personnel during the construction process, safety management related to road construction machinery must be done well.

When constructing highways, the use of road construction machinery has always been a major issue worthy of attention. A series of issues such as the quality of highway completion are closely related to this. Repair and maintenance of road construction machinery are the guarantee for completing production tasks. Correctly handling the use, maintenance and repair of machinery is a crucial issue in the mechanized construction of modern highway construction enterprises.

There is also a reversing valve in the asphalt mixing plant, which generally does not cause problems, so I have not understood its solutions in detail before. But in actual use, we encountered this kind of failure. How should we deal with it?
