The dung suction truck is a special vehicle used to clean up sludge and sewage in septic tanks, sewers and sewage ditches. The dung suction truck has a fixed elliptical cylinder tank, which is used to store and transport sludge and sewage. Because the sludge sewage is corrosive, we need to regularly clean the tank of the dung suction truck in order to prolong the service life of the dung suction truck. Next, let me introduce to you the cleaning method of the tank body of the dung suction truck.
Before cleaning up the tank of the dung suction truck, we need to talk about that we should clean the sewage sludge in the tank of the dung suction truck as cleanly as possible. The tank of the dung suction truck is different from that of the dirt suction truck. The tank body of the suction truck can be lifted, the back cover can be opened, and the dirt in the tank can be easily discharged. The tank body of the dung suction truck is fixed and can not be lifted. When discharging sewage sludge, it is easy to leave a part of sewage sludge in the tank. To clean up the sewage sludge in the tank of the dung suction truck, we can find a slope to stop the truck, with the high head and the lower tail bottom, so that the sludge sewage flow out of the tank naturally.
After the sewage sludge in the suction tank is completely discharged, we should open the manhole on the top of the suction tank and the sewage outlet. After a short period of air circulation, the sewage sludge can enter the tank and start cleaning the tank. A long hose is connected to the tap. By using the pressure of the tap water itself, all parts of the inner wall of the suction tank are flushed, and the dirt adhering to the inner wall is washed out. If you wash with a high-pressure water gun, the effect is better. Rinse carefully and try to rinse out as much as possible. Don't let go of any corners. The flushed sewage will flow out of the sewage outlet.
When the suction truck sucks sludge sewage, the suction force is bigger, which will inevitably inhale sand stones, and are deposited in the tank and are not easy to be discharged. After we flush the inner wall of the suction tank, we also need to clean up the sand and stone deposited at the bottom of the tank. If these sand stones are left in the tank, more and more sediments will be deposited, which will increase the load of the dung suction truck and occupy the volume of the dung suction truck. At the same time, the stones at the bottom of the tank move with the sloshing of the sewage and produce abnormal sound during the driving process of the dung suction truck, which easily distracts the driver's attention. To clean up the sediment in the tank of the dung suction truck, people need to enter the tank through manholes, and shovel the sediment out of the sewage outlet with spade and other tools.
After cleaning the inside of the suction tank, the cleaner will come out through the manhole and bring out all the cleaning tools. Don't leave the tools in the tank. When the cleaner comes out, remember to close the manhole on the top of the dung suction truck.
In this way, the inside of the tank of the dung suction truck is cleaned up totally.
Because the tank of the dung suction truck contains sewage, sludge, feces and so on, it will have a very large odor and a large number of bacteria, so attention should be paid to ventilation in the process of cleaning the tank of the dung suction truck. Cleaners need to wear protective glasses and anti-virus masks to prevent sewage from splashing into glasses and inhaling harmful gases.
