Fecal suction truck solid-liquid separation device

Abstract

The invention relates to a fecal suction truck solid-liquid separation device. The device comprises a tank, a feces storage bucket is arranged on the tank, water outlets are densely formed in a bucketbody of the feces storage bucket, a water outlet and a residue outlet are formed in the tail end of the tank, and the feces storage bucket is communicated with the residue outlet; the device is characterized in that a multistage telescopic oil cylinder and an extrusion oil cylinder are arranged on the two sides of the feces storage bucket respectively, the multistage telescopic oil cylinder is located in the tank, the extrusion oil cylinder is located outside the tank, an extrusion plate is connected to pistons of the multistage telescopic oil cylinder and the extrusion oil cylinder and located in the feces storage bucket, and the diameter of the extrusion plate is equal to the inner diameter of the feces storage bucket. Accordingly, the solid-liquid separation effect is good, the failurerate is low, the energy consumption is low, the labor intensity of workers can be greatly lowered, and the application range is wide.

Description

technical field [0001] The invention relates to the field of special vehicles, in particular to a solid-liquid separation device for a fecal suction vehicle. Background technique [0002] Fecal suction trucks are mainly used in special vehicles for cleaning and cleaning in septic tanks, sewage ditches, sewers and other environments, together with sprinklers and garbage trucks, they are also known as the three major sanitation models. [0003] At present, the fecal suction trucks and sewage suction trucks refitted in my country have no separation mechanism, which sucks the dirt and sewage into the sealed tank and pulls them to other places for discharge. Although the septic tank sewage hardening treatment machine and the sewage and sewage separator have a separation mechanism, there are many shortcomings. First, the structure is complex and the cost is high. It needs to be equipped with a generator set for power supply, which drives the vacuum pump for suction and discharge o...

AI Technical Summary

Problems solved by technology

[0005] The solid-liquid separation device in this utility model is realized by the screw conveyor in the separation cylinder, but this method has the following disadvantages: 1. When encountering long or soft objects, it is easy to wrap around the conveyor, causing the conveyor to jam 2. As long as the engine works, the screw conveyor will rotate for as long as it takes, and the energy consumption is high; 3. It is necessary to manually remove the dried dung, and the labor intensity of the workers is very high.
