Efficient double-circulation desilting system

Abstract

The invention relates to an efficient double-circulation desilting system. The efficient double-circulation desilting system involves two collecting boxes with the same structure, wherein the collecting boxes are provided with feeding openings, water inlets and water outlets; the water inlets of the two collecting boxes are jointly provided with and communicate with a first three-way electromagnetic valve, and the water outlets of the two collecting boxes are jointly provided with and communicate with a second three-way electromagnetic valve; and control systems for controlling the first three-way electromagnetic valve and the second three-way electromagnetic valve to change communication of channels are arranged in the collecting boxes, cleaning systems used for cleaning the inner side walls of the collecting boxes are arranged in the collecting boxes, and an inlet of the first three-way electromagnetic valve is provided with and communicates with a telescopic suction device. By the adoption of the technical scheme, the effect of automatically replacing different collecting boxes is achieved, and silt suction operation can be continuously carried out, so that the desilting operation efficiency is improved; the cleaning systems are used for cleaning silt deposited on the inner side walls of the collecting boxes, so that the service life of the collecting boxes is prolonged; andthe telescopic suction device is convenient for a suction pipe to extend into a drainage pipe for desilting.

Description

technical field [0001] The invention relates to the technical field of pipeline dredging, in particular to an efficient double-cycle dredging system. Background technique [0002] At present, the urban underground drainage pipe is an important system to prevent urban waterlogging and drainage. As the service life of the drainage pipe increases, a certain amount of silt will accumulate in the drainage pipe, which reduces the drainage efficiency. The drainage pipe needs to be dredged to maintain smooth drainage. . [0003] Existing dredging work is generally carried out by dredging equipment, such as a pipeline dredging equipment disclosed in a Chinese patent with application number CN201820290248. After the sludge is sucked by the silt pipe, it is collected in the pre-installed collection box on the equipment for temporary storage or pretreatment. Conventional pretreatment operations include throwing flocculants into the collection box, settling the sludge sucked into the c...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the collection box of the existing dredging equipment is often filled with silt and put in the flocculant, and the suction work of the dredging pipe is in a state of stagnation, and dredging cannot be carried out continuously work, resulting in a reduction in the efficiency of dredging, so there is room for improvement
