Description

Technical Field

[0001] The utility model relates to the technical field of sludge cleaning, in particular to a silt cleaning device for a water conservancy project. Background Art

[0002] Siltation in canals can easily affect the normal functioning of flood control, drainage, irrigation, water supply, navigation and other functions. In order to restore the normal functions of the river, river dredging projects are needed. Hydraulic engineering dredging equipment is a mechanical equipment specially used to clear silt from rivers, reservoirs and other water bodies. Through mechanical equipment, the silt deposited on the riverbed is blown and stirred into turbid water, and then the silt is pumped to the designated mud storage point through a sewage pump.

[0003] At present, when dredging most rivers, it is usually necessary to break up the lumpy silt in the river channel with a high-pressure water gun, which can increase the water volume of the silt blocks and disperse the silt to ensure good fluidity of the silt. Since the impact range of the water gun is limited each time, during the dispersion process, workers need to keep moving and need to perform multiple impacts, which makes the process more cumbersome and the silt crushing and cleaning efficiency is low.

During the rotation of the rotating roller, the harrowing blade fixed between the rotating roller and the fixed ring is driven to rotate, and the agglomerated sludge is cut into pieces while the silt cleaning box is driven to move. The cut sludge is cut off by the inclined plate as the silt cleaning box moves and is pushed into the silt cleaning box by the subsequent sludge. During the movement of the sludge on the inclined plate, the high-pressure nozzle sprays high-pressure water flow at an angle to decompose the block sludge after the cutting and completely pushes it into the silt cleaning box to wait for the sewage pump to pump it out, thereby realizing the rapid decomposition and silt discharge of the block sludge and improving the efficiency of sludge crushing and cleaning.
