[0003] During the use of the existing sewage treatment sludge cleaning pump, large pieces of hard sludge impurities or high-hardness scrap iron objects such as screws in the sludge enter the pump casing, which can easily cause damage to the impeller inside the pump casing or blockage inside the pump casing. For this reason, we propose a sewage treatment sludge cleaning pump. Utility Model Content

[0004] The purpose of the utility model is to provide a sewage treatment sludge cleaning pump, which has the advantage of being able to prevent large pieces of hard sludge impurities or high-hardness scrap iron objects such as screws in the sludge from entering the pump body and causing wear or damage to the impeller, thereby extending the service life of the cleaning pump. It solves the problem of existing sewage treatment sludge cleaning pumps that during use, large pieces of hard sludge impurities or high-hardness scrap iron objects such as screws in the sludge enter the pump casing, which easily causes damage to the impeller inside the pump casing or blockage inside the pump casing.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: it includes a rotating motor, a connecting seat and a pump casing, a connecting pipe is welded to the lower surface of the connecting seat, the end of the connecting pipe is fixedly connected to the pump casing, a transmission shaft is rotatably installed inside the connecting pipe, one end of the transmission shaft located inside the pump casing is fixedly connected to a rotating shaft, an impeller is fixedly sleeved on the outer surface of the rotating shaft, a blade is fixedly installed on the outer surface of the rotating shaft near the lower surface of the pump casing, a support rod is welded to the lower surface of the pump casing, and a magnet is fixedly installed on the outer surface of the support rod.

[0007] Preferably, a mud discharge pipe is welded to one side of the outer surface of the pump casing, and the sludge inside the pump casing is discharged from the mud discharge pipe.

[0008] Preferably, a mud inlet is provided on the lower surface of the pump casing, and sludge enters the interior of the pump casing through the mud inlet.

[0009] Preferably, there are four blades in total, and the four blades are fixedly installed in a circular array at equal distances on the outer surface of the rotating shaft near the lower surface of the pump casing. The rotating blades break up large pieces of hard sludge impurities before entering the pump casing, reducing the wear of the impeller.

[0012] The utility model achieves the effect of preventing large pieces of hard sludge impurities or high-hardness scrap iron objects such as screws in the sludge from entering the interior of the pump body and causing wear or damage to the impeller, thereby extending the service life of the cleaning pump by arranging blades and magnets. When in use, the motor is rotated to work and the rotating shaft, impeller and blades are driven to rotate through the transmission shaft. Before the sludge enters the interior of the pump casing, the magnet absorbs the screws and other iron objects in the sludge to prevent them from entering the interior of the pump casing. At the same time, large pieces of hard sludge impurities are broken up by the rotating blades before entering the interior of the pump casing, thereby avoiding large wear and even damage to the impeller.
