Dirt box assembly for tunnel cleaning vehicle and tunnel cleaning vehicle

Technical Field

The utility model belongs to the technical field of sewage treatment, concretely relates to dirt case subassembly and tunnel cleaning car for tunnel cleaning car.

Background

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

Due to poor air fluidity in the subway tunnel, pollutants such as dust, garbage and the like are inevitably brought into the tunnel under the action of long-term piston wind, and the dust, the garbage and the sewage are accumulated on the ground, walls and the surfaces of various devices all the year round, so that the phenomena of short circuit of electrical equipment, poor contact of an electrical switch and the like can be caused in serious cases, and the driving safety and the health of personnel are endangered. The appearance of tunnel washs the car and has solved artifical clean inefficiency, danger coefficient height scheduling problem. The tunnel cleaning vehicle can store collected dust, garbage, sewage and the like into a sewage box on the vehicle, and the vehicle can finish operation and then stand to discharge and clean the garbage, particularly the sewage, in the sewage box.

However, the inventor believes that the existing waste bin has the following disadvantages:

(1) after the solid waste enters the sewage tank in a collecting mode, the solid waste is not easily and uniformly distributed in a solid waste storage chamber of the sewage tank and is easily accumulated into a group, so that the solid waste and sewage are not easily separated through the filter plate, and the solid waste is required to be discharged from a waste outlet by utilizing the rake because the solid waste is irregularly distributed.

(2) After the waste water in the solid waste is collected or the external sewage is directly pumped through the sewage pumping and discharging pipeline, the secondary treatment of the sewage cannot be realized, the direct discharge of the sewage not only wastes water resources but also causes secondary pollution to the environment, and the requirements of environmental protection, energy conservation and emission reduction are not met.
