A detailed description of sewage tank semi-trailer

Sewage tank semi-trailer is made of ordinary dump trucks with a closed cargo top cover. The cargo compartment is tilted when unloading, and the sewage is automatically discharged by gravity. This method of unloading sewage can only unload sewage to a position lower than the carriage. When unloading, the sewage is flying and the blanking area is large. The ash discharging semi-trailer uses a screw conveyor mounted on the car to discharge ash and adjust the height of the screw conveyor. The sewage can be discharged to different heights, and the flying of sewage can be reduced, but the ash unloading mechanism is easy to wear due to the direct push of sewage. Appeared in the 1960s, it is relatively easy to use. Its cargo compartment is a tank container, which is placed upright or inclined on the car frame. The center of gravity of the horizontal tank is low, and the vehicle runs stably, and it is used more. The tank body is welded by a steel plate or aluminum plate, or it can be made of glass steel.
