When the bitumen decanter equipment is cleaned, diesel is generally used. If there is thickness, it can be cleaned first by physical means, then washed with diesel. The ventilation system is activated when the cavern is pumping the bottom oil to ensure ventilation at the work site. It is prone to oil and gas poisoning accidents during the removal of dirt from the bottom of the dewatering equipment of asphalt, and it is necessary to do a good job of protection. In addition to this, check the technical status of the ventilation equipment and start the ventilation of the fan. The tunnel de-barrel equipment and the semi-subterranean bitumen decanter equipment shall be continuously ventilated and ventilated. When the ventilation is stopped, the hole on the bitumen decanter equipment shall be sealed. The inspector's protective clothing and respirator meet the requirements; check whether the tools and equipment (wood) are in compliance with the explosion-proof requirements, and then enter the bitumen decanter equipment to remove the dirt.

In the process of using the bitumen decanter equipment, sudden power failure or circulatory system failure, in addition to ventilation cooling, the cold heat transfer oil is replaced, the replacement should be fast and orderly. During the replacement process, the opening degree of the oil valve follows the law from large to small, so as to extend the replacement time as much as possible while ensuring that there is enough cold oil for replacement, so that the bitumen decanter is not in an oil-free or oil-less state.
