Efficient double circulation dredging system

Abstract

The invention relates to a high-efficiency double-circulation dredging system, which includes two sets of collection boxes with the same structure. The collection boxes are all provided with feeding ports, water inlets and water outlets; the water inlets of the two sets of collection boxes are installed together and communicated with a first Three-way solenoid valve, the water outlets of the two sets of collection boxes are installed together and communicated with the second three-way solenoid valve; the collection box is equipped with a control system that controls the first three-way solenoid valve and the second three-way solenoid valve to change the conduction channel ; The collection box is provided with a cleaning system for cleaning the inner wall of the collection box, and the inlet of the first three-way solenoid valve is installed and communicated with a retractable suction device. By adopting the above technical solution, it has the effect of automatically replacing different collection boxes, can continuously carry out the sludge suction operation, and improves the efficiency of dredging operation. The cleaning system is used to clean the sludge deposited on the inner wall of the collection box to improve the service life of the collection box. The retractable suction device facilitates extending the suction pipe into the drain for dredging.

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...
