Dredging vehicle for cleaning sewer at inspection well

Abstract

The invention relates to a dredging vehicle for cleaning a sewer at an inspection well. The dredging vehicle comprises a traction vehicle head, wherein a chassis is connected and mounted to the tail of the traction vehicle head, and a sealed sludge collection box is arranged on the chassis; the sludge collection box is internally provided with a screw press sludge dehydrator, and the screw press sludge dehydrator is provided with a sludge inlet, a compressed sludge outlet and a press sewage outlet; the compressed sludge outlet is located in the sludge collection box, and the press sewage outlet is connected with a blow-off pipe at the outer side of the sludge collection box; the sludge inlet is connected with a sinking sludge pump through a hose, and the outer side of the sinking sludge pump is provided with a water pump cover; the end of the water pump cover is provided with a water absorption hole, and the end of a water pump rotating shaft of the sinking sludge pump extends into thewater pump cover; the water pump rotating shaft is sleeved with a connection sleeve, and the circumferential surface of the connection sleeve is provided with a plurality of cutting leaf assemblies.Separation of water and sludge is realized, and the sludge can be taken away while sewage is discharged into the sewer.

Description

technical field [0001] The invention relates to the field of sewer dredging vehicles, in particular to a dredging vehicle for cleaning sewers at inspection wells. Background technique [0002] The inspection well is set at the turn, branch, drop, etc. of the drainage pipe for inspection and dredging of the sewer pipe. Because the water velocity of tiny solid particles mixed in the inspection well will slow down, most of the solid particles will form a large amount of silt at the inspection well due to alluvial action, so that the pipeline will be blocked and need to be cleaned up in time. At present, the cleaning method of the silt at the inspection shaft is mainly manual salvage and cleaning, and some grab-type dredging vehicles are used. Manual salvage is not only a huge workload, but also the working environment is full of peculiar smell and poisonous gas; the grab dredger has a simple structure and can simply replace manual dredging, but because of the manual operation,...

AI Technical Summary

Problems solved by technology

Manual salvage is not only a huge workload, but also the working environment is full of peculiar smell and poisonous gas; the grab dredger has a simple structure and can simply replace manual dredging, but because of the manual operation, the operation is slow and difficult promotion, and due to visual errors, there is a problem of poor positioning accuracy during the inspection shaft dredging process, and the operator needs to repeatedly adjust the grab

The stability of the grab action is poor, the artificial labor capacity is strong, and the work efficiency is low

The sludge cleaned by the two dredging methods contains a large amount of liquid, which has a strong odor and is not conducive to subsequent treatment
