The main feature of bitumen tank heating is combustion and preheating. Both the high temperature unit and the steam generator are installed in the bitumen tank to form a whole, with brackets (Y-type) or chassis (T-type). Such an bitumen tank heating device has high thermal efficiency, fast heating speed, simple operation and very convenient movement. So what are the precautions for bitumen tank heating? The following is a detailed introduction to the correct method of bitumen tank heating:
Before heating the emulsified asphalt in the bitumen tank, the equipment should be cleaned to prevent it from reacting with the original emulsified asphalt. In initial production, the emulsion valve should open the bitumen valve after the colloid has flowed out. The content of asphalt gradually increases from 35%. During the production process, it is found that the colloidal grinding force or emulsified asphalt begins. At this time, the flocculated aggregate should immediately reduce the amount of asphalt in it, and then flush the emulsifier solution valve for about 30 seconds, and turn off the emulsifier at the same time. Solution valve to prevent the modified bitumen remaining in the colloid mill from affecting the next production.
The emulsified asphalt equipment should be completely inspected before it can be used. After the transformation is completed, only when the pipeline and valve switches are in a good development state, can the oil be supplied to ensure preheating, and the temperature of the cylinder chamber will increase by more than 150 ℃. In the process of operation management, in order to avoid being scalded or tangled by the transmission chain, the operating staff need to pay attention to the safety of their own operation information.
Nowadays, the heating technology of bitumen tanks is gradually coming into contact with electric heating, especially in projects such as road construction projects. That is how the circulating oil mold temperature machine we mentioned below is applied to bitumen tank equipment.
At present, many sets of heating wires are installed at the bottom of the bitumen tank, which can reach more than 200 degrees, so that the temperature of the asphalt can reach 170 or 80 degrees. The usual bitumen tank heating is mostly heated by electric heating wires or gas molds. The disadvantage of this method is that there are too many groups of heating wires, which is very troublesome to replace, and it is also very troublesome to install, and the pipelines connecting the bitumen tanks also need to be heated and insulated. So how is the circulating oil mold temperature machine improved?
First of all, due to environmental problems, many places do not allow the use of gas and diesel, and electric heating is the development trend. Secondly, we use the heat transfer oil to heat the bottom of the bitumen tank through the circulating oil mold temperature machine. At the same time, the heat transfer oil can be circulated to the pipeline connected between the bitumen tanks for heating and heat preservation. It is controlled centrally on the PLC, and the alarm and operation feedback can be displayed on the mobile phone remotely. Greatly avoid the waste of labor costs and various security risks.
