[0024] The working principle of this utility model is as follows: When a small pumping station needs to drain water and clear silt, the entire equipment is first placed in the water mixed with silt in the small pumping station. The lower end of the support frame 9 is supported in the silt. After the motor 1 is turned on, the motor 1 drives the impeller 4 to rotate, and at the same time drives the transmission shaft 84 to rotate. The transmission shaft 84 drives the active bevel gear 85 and the crushing blade 89 to rotate together. Since the active bevel gear 85 and the two driven bevel gears 83 mesh and drive each other, the driven bevel gears 83 drive the corresponding stirring shaft 82 and the auger 87 to rotate together. Through the rotation of the auger 87, the silt on the outside of the support frame 9 is stirred, so that it is fully mixed with water to form a flowing mud-water structure. This causes the silt liquid phase to flow inside the support frame 9. Then, the rotation of the crushing blade 89 breaks up the mud-water structure inside the support frame 9, making the structure smaller and finer.

[0025] During the rotation of impeller 4 driven by motor 1, centrifugal force is generated, which throws out the mud and water between impeller 4 and discharges it from outlet 3. As the liquid is continuously thrown out, a low-pressure zone is formed at the center of impeller 4. The mud and water at support frame 9 are fed upward into hood 6 under atmospheric pressure. After being filtered by filter cylinder 5 to remove large hard particles in the mud and water, the mud and water are sucked into the center of impeller 4 inside pump body 2 and discharged from outlet 3, thereby achieving continuous drainage and sludge removal.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
