Abstract

The invention provides an auxiliary suction mechanism for a sewage suction truck and the sewage suction truck. The mechanism comprises an outer cylinder, an inner cylinder, a hydraulic motor, a bearing, an oil conduit, a negative pressure transducer, an magnetic exchange valve and a gear pump, external teeth are arranged on the outer side surface of the inner cylinder, a work station hole is formed in the middle of the outer cylinder, and a helical blade is arranged on the inner wall of the inner cylinder. When a sewage suction pipe sucks blocky deposits, medium resistance in the sewage suction pipe can be increased, the suction speed of the sewage suction truck is slowed down, and even the blocking and stagnation situations are likely to occur. When the value obtained by the negative pressure transducer reaches a preset value, the auxiliary suction mechanism is started, the helical blade in the inner cylinder rotates, the blocky deposits are crushed, and the blocky deposits are suckedvery hard to be pushed into a storage tank. Therefore, the work efficiency of suction of the sewage suction truck is improved, the blocky deposits can be crushed effectively through the auxiliary suction mechanism, the phenomenon that the sewage suction pipe is blocked is prevented, the problem that a vacuum pump is too heat is avoided, and the service life of the vacuum pump is prolonged.

Description

technical field [0001] The invention relates to the field of garbage cleaning devices, in particular to an auxiliary suction mechanism of a sewage suction vehicle and the sewage suction vehicle. Background technique [0002] At present, domestic sewage suction trucks generally use the principle of vacuum negative pressure suction to suck sewage, that is, first use a vacuum pump to evacuate the tank body, and then use atmospheric pressure to press the liquid sewage into the tank body through the sewage suction pipe, so as to achieve suction. purpose of sewage. Among them, the sewage suction pipe is connected between the tank body of the sewage suction truck and the sewage, and then the sewage is sucked into the tank body, and the sewage suction process will be limited by the atmospheric pressure, so when the suction medium is relatively viscous, When the density is high or when the large lumpy sludge is sucked, the speed of vacuum suction will slow down, and the sewage sucti...
