Sludge suction system of sewage suction truck

Abstract

The invention discloses a sludge suction system of a sewage suction truck. The sludge suction system comprises a suction device, a connection device and an exhausting device. The suction device comprises a suction pipe, a transmission sleeve, a motor, a crushing cutter and a ventilation pipe, wherein the transmission sleeve is installed at the inlet end of the suction pipe in a sleeving mode, the motor is fixedly connected to the suction pipe, a rotation shaft of the motor is connected to the transmission sleeve in a transmission mode, the crushing cutter is arranged on the inlet of the suction pipe and is fixedly connected to the transmission sleeve, the ventilation pipe is fixedly connected to the suction pipe, the inlet of the ventilation pipe is communicated with an air source, and the outlet of the ventilation pipe is formed in the inlet of the suction pipe. The connection device comprises a connection pipe made of a transparent material, one end of the connection pipe is connected with the suction pipe of the suction device of the sewage suction truck, and the other end of the connection pipe is connected with an input pipe of a separation device of the sewage suction truck. The exhausting device comprises a main exhausting pipe and an auxiliary exhausting pipe, the inlet end of the auxiliary exhausting pipe is located in front of a first valve and is communicated with the main exhausting pipe, and the outlet end of the auxiliary exhausting pipe is communicated with the ventilation pipe of the suction device.

Description

technical field [0001] The invention relates to sanitation cleaning equipment, in particular to a sludge suction system of a sewage suction truck. Background technique [0002] When the suction device of the ordinary sewage suction truck currently used is used for suction operations on septic tanks, river loops and fish ponds, most Stains or sludge contain sanitary napkins, rotten tree roots, grass, wood and other agglomerated substances, which can easily block the suction pipe, making the suction operation difficult, low work efficiency, high energy consumption, and the suction distance of the sewage suction truck Short, the general sewage suction truck can only suck the silt from rivers and ponds for a distance of more than ten meters, and the height is within six meters, which is inconvenient. Secondly, the connecting pipes connecting the suction device and the separation device of the sewage suction truck are all made of rubber pipes or other opaque materials. Since th...

AI Technical Summary

Problems solved by technology

Since the connecting pipe is made of rubber tube or other opaque materials, when the suction device is working, it is not possible to visually observe whether the suction pipe of the suction device is blocked by impurities, and the experience of the staff can only be used to judge whether the suction pipe of the suction device is Blocked by impurities, the suction device must be guarded by experienced staff when it is working, wasting resources, high cost, and inconvenient

Thirdly, the engine exhaust pipe of the sewage suction truck directly discharges the exhaust gas into the air. When the equipment on the sewage suction truck needs gas to work, such as the stirring device needs to add gas to stir, and the suction device needs to add gas to disperse Inhalation of silt, etc., is achieved by adding other air sources, a waste of resources, high cost, and inconvenient
