The crushing roller 14 is located on the upper part of the outlet cover 15, and the crushing roller 14 can effectively crush and cut impurities to prevent impurities from blocking the outlet. The crushing roller 14 is connected to the runner 12 through a transmission belt 13. The outlet cover 15 is movably connected to the side of the sewage tank 1. The impeller 8 passes through the side of the circular chamber 5 and a sealing rubber ring is provided at the connection between the impeller 8 and the circular chamber 5 to prevent the sewage in the circular chamber 5 from leaking due to the rotation of the impeller 8. The utility model drives the bevel gear 1 9 to rotate through the impeller 8, and the crushing roller 14 is driven to rotate through the mutual cooperation between the bevel gear 2 10 and the transmission rod 11 and the transmission belt 13. The staggered sheet structure on the surface of the crushing roller 14 is arranged, so that the sludge and impurities at the bottom of the sewage tank 1 are crushed, and the problem of impurities accumulation and difficulty in cleaning is avoided, so that the internal cleaning of the sewage tank 1 is more convenient and simple, and the outlet is avoided.

[0021] When in use, first connect the first water pump 2 and the second water pump 3 to the water outlet pipe of the water pump below, and drive the water pump to lift the sewage in the water outlet pipe to the water delivery pipe 4, and the sewage enters the circular chamber 5 through the water delivery pipe 4, and makes the sewage flow out through the water outlet 6. At this time, the impeller 8 is driven to rotate by the pressure of the sewage, and the rotation of the impeller 8 drives the bevel gear 1 9 to rotate. The transmission rod 11 rotates through the cooperation between the bevel gear 1 9 and the bevel gear 2 10, and the transmission rod 11 drives the runner 12 to rotate, so that the runner 12 drives the transmission belt 13 to drive, and the transmission belt 13 drives the crushing roller 14 to rotate synchronously. Under the action of gravity and the water column spraying of the self-cleaning pipe 7, the impurities and sludge inside the sewage tank 1 enter the periphery of the crushing roller 14, and the staggered sheet structure on the surface of the crushing roller 14 is set, so that the sludge and impurities at the bottom of the sewage tank 1 are crushed, so that the problem of impurity accumulation and difficulty in cleaning is avoided, and the internal cleaning of the sewage tank 1 is more convenient and simple.

The center of the rotating shell 16 is located on the extension line of the center of the self-cleaning pipe 7. The top arc length of the blades of the rotating impeller 18 is smaller than the bottom arc length, and each blade has a certain inclination angle, so that the water pressure on the rotating impeller 18 is uneven and rotates. When the water flow inside the self-cleaning pipe 7 of the utility model is sprayed downward, the water flow first contacts the rotating impeller 18. Due to the bending angle of the blades of the rotating impeller 18, the water flow vertically impacts the rotating impeller 18 while driving the rotating impeller 18 to rotate. The water flow splashes around through the flushing ports 17 under the centrifugal force, and the spraying range of the self-cleaning pipe 7 is increased.

[0023] During use, based on the first embodiment, when the water flow inside the self-cleaning pipe 7 is sprayed downward, the water flow first contacts the rotating impeller 18. Since the blades of the rotating impeller 18 have a bending angle, the water flow vertically impacts the rotating impeller 18 while driving the rotating impeller 18 to rotate. At the same time, under the action of the rotating impeller 18, part of the water flow is diverted to the surroundings, and the rotating impeller 18 drives the rotating shell 16 to rotate, so that the water flow splashes to the surroundings through the flushing port 17 under the centrifugal force, and the spray range of the self-cleaning pipe 7 is increased.
