Abstract

The invention relates to a cavitation jet sludge cleaning device, and belongs to the technical field of underwater sludge cleaning equipment. The cavitation jet sludge cleaning device comprises an underwater sludge layer, a dredging underwater operation vehicle is arranged on the underwater sludge layer, a cavitation jet sludge cleaning mechanism is arranged at the front end of the dredging underwater operation vehicle, a mechanical arm is arranged between the cavitation jet sludge cleaning mechanism and the dredging underwater operation workshop, a suction pump is arranged on the dredging underwater operation vehicle, a sludge conveying pipe extending out of the water surface is arranged between the suction pump and the cavitation jet sludge cleaning mechanism, a jet pump is arranged on the side edge of the suction pump, and a jet pipe is arranged between the jet pump and the cavitation jet sludge cleaning mechanism. The device has the characteristics of simple structure, good operation stability, high working efficiency and long service life; and pulse cavitation jet flow is formed through an outlet of a generator nozzle, hydraulic pulses and an instantaneous negative pressure effect are generated, the sludge crushing and scattering effect is improved, and follow-up sludge suction work is facilitated.

Description

technical field [0001] The invention relates to the technical field of underwater sludge cleaning equipment, in particular to a cavitation jet sludge cleaning device. Background technique [0002] Due to the needs of flood control and environmental protection, people often need to clean up the silt deposited in rivers, lakes, dams and other deep water systems. At present, the commonly used dredging methods include dredgers, chain bucket dredgers and pump suction dredgers, etc., all of which need to rely on onboard equipment for work. Such equipment is complex in structure, difficult to operate, and expensive to use. And the cleaning depth should not be too large. [0003] For deep-water sludge cleaning, the sludge is mainly broken and dispersed by the dredging truck using the rotating mud scraper head on the dredging head, and then sucked into the trolley. The dredging head in this way works on the solid-liquid contact surface, and the rotating work of the crushing cutter ...
