What work should be done to clean the asphalt heating tank of the pavement joint filling machine?
In use, the asphalt heating tank has the advantages of intelligent and high efficiency, low investment, low power consumption, low cost, high thermal efficiency and fast heating up. It can meet the construction requirements in a short time, which also indirectly saves a lot of manpower and material resources for users. Moreover, the asphalt heating tank has less accessories, simple operation and convenient movement, and can operate a single set of heater by one person. What work should be done to clean the asphalt heating tank?
When cleaning the asphalt heating tank, the asphalt will be softened and flowed out at a temperature of about 150 ℃. The residual part on the wall can be cleaned with kerosene, gasoline and benzenes chemical reagents. Generally, the asphalt heating tank is cleaned with diesel oil. If there is a certain thickness, it can be cleaned by physical method first, and then cleaned with diesel oil. The ventilation system is started when the bottom oil is pumped into the cavern to ensure the ventilation and ventilation of the workplace.
Oil and gas poisoning accidents are very easy to occur during the cleaning of tank bottom dirt, and protection work should be done well. In addition, it is necessary to check the technical status of ventilation equipment and start the fan for ventilation. Ventilation and air exchange should be carried out continuously for the asphalt tank in the cavern and semi underground asphalt tank. When the ventilation is stopped, the upper orifice of the asphalt tank must be sealed. Check that the protective clothing and respirator meet the safety requirements; check whether the tools and equipment used meet the explosion-proof requirements, and enter the asphalt tank to remove the dirt after passing the inspection.
The asphalt heating tank should pay attention to these matters when cleaning, we should operate reasonably, so that its performance can be fully displayed.
