[0021] The pump body 1 is the main body of the sludge pump, and the internal circulation part 2 is the main channel for the sludge to flow. The design of the sewage inlet 3 allows the sludge to enter the circulation part 2 smoothly, and the sewage outlet 4 ensures that the sludge can be discharged smoothly. The columnar shape of the circulation part 2 and the arc-shaped sewage inlet 3 and sewage outlet 4 help to reduce the resistance of the sludge during the flow process, thereby improving the working efficiency of the sludge pump;

[0022] When the sludge enters the circulation part 2, the sludge will impact on the movable plate 7, driving the multiple sets of movable plates 7 to rotate on the vertical pipe 5 through the ring 6. During the rotation of the movable plate 7, the sludge adhering to the inner wall of the circulation part 2 will be automatically scraped off, and the sludge will flow through the top opening of the vertical pipe 5 to the sewage outlet 4 for discharge;

[0023] The sludge pump structure can effectively prevent sludge from adhering to the inside of the pump body 1, thereby reducing blockage and dirt accumulation problems inside the pump body 1, improving the working efficiency of the sludge pump, reducing maintenance costs, and extending the service life of the pump, and is highly practical.

[0024] The vertical tube 5 and the side wall of the circular ring 6 are both provided with evenly distributed openings 8, and the movable plate 7 is fixedly provided with evenly distributed openings 9;

[0025] The vertical pipe 5 is the core component for sludge circulation and is connected to the sewage outlet 4 to ensure that the sludge can be discharged smoothly. The ring 6 and the movable plate 7 thereon rotate in the vertical pipe 5. The opening 9 on the movable plate 7 and the opening 8 on the vertical pipe 5 work together to form a dynamic circulation channel, which helps to prevent sludge from accumulating in the vertical pipe 5 and reduce the possibility of blockage.

[0026] A rubber strip 10 is arranged on one side of the movable plate 7 close to the inner wall of the circulation part 2, the rubber strip 10 is in contact with the inner wall of the circulation part 2, and the edge of the rubber strip 10 is arranged as an arc edge;

[0027] The rubber strip 10 disposed on one side of the movable plate 7 close to the inner wall of the circulation part 2 is tightly fitted to the inner wall of the circulation part 2. The presence of the rubber strip 10 can further scrape off the sludge adhered to the inner wall of the circulation part 2, thereby improving the cleaning effect.

[0028] The movable plates 7 are fixedly mounted with uniformly distributed cutting blades 11, and the number of groups of the cutting blades 11 is the same as the number of groups of the openings 9;

[0029] The cutting blade 11 is fixed on the movable plate 7 and works with the rotation of the movable plate 7. When the sludge passes through the circulation part 2, the cutting blade 11 can effectively break up the large particles and fibers in the sludge to prevent them from clogging the circulation channel, which not only improves the fluidity of the sludge, but also reduces the blockage and dirt accumulation problems inside the pump body 1.

[0030] The circulation part 2, the vertical tube 5, the ring 6, the movable plate 7 and the cutting blade 11 are all made of corrosion-resistant alloy material, and the surfaces of the circulation part 2, the vertical tube 5, the ring 6, the movable plate 7 and the cutting blade 11 are sprayed with polytetrafluoroethylene;

At the same time, the polytetrafluoroethylene coating sprayed on their surfaces further enhances the anti-adhesion performance and reduces the accumulation and adhesion of sludge inside the pump body 1.

[0032] A sludge flow sensor is provided at the sewage outlet 4, and a controller is provided on the pump body 1, and the controller is electrically connected to the sludge flow sensor;

[0033] The sludge flow sensor arranged at the sewage outlet 4 can monitor the sludge flow in real time and feed the data back to the controller, so as to monitor and control the flow of the pump body 1 in real time.

[0034] Working principle:

[0035] The pump body 1 is the main body of the sludge pump, and the internal circulation part 2 is the main channel for the sludge to flow. The design of the sewage inlet 3 allows the sludge to enter the circulation part 2 smoothly, and the sewage outlet 4 ensures that the sludge can be discharged smoothly. The columnar shape of the circulation part 2 and the arc-shaped sewage inlet 3 and sewage outlet 4 help to reduce the resistance of the sludge during the flow process, thereby improving the working efficiency of the sludge pump;

[0036] When the sludge enters the circulation part 2, the sludge will impact on the movable plate 7, driving the multiple sets of movable plates 7 to rotate on the vertical pipe 5 through the ring 6. During the rotation of the movable plate 7, the sludge adhering to the inner wall of the circulation part 2 will be automatically scraped off, and the sludge will flow through the top opening of the vertical pipe 5 to the sewage outlet 4 for discharge;

[0037] The sludge pump structure can effectively prevent sludge from adhering to the inside of the pump body 1, thereby reducing the blockage and dirt accumulation problems inside the pump body 1, improving the working efficiency of the sludge pump, reducing maintenance costs, and extending the service life of the pump, and has strong practicality;

[0038] The vertical pipe 5 is the core component for sludge circulation and is connected to the sewage outlet 4 to ensure that the sludge can be discharged smoothly. The ring 6 and the movable plate 7 thereon rotate in the vertical pipe 5. The opening 9 on the movable plate 7 and the opening 8 on the vertical pipe 5 work together to form a dynamic circulation channel, which helps to prevent sludge from accumulating in the vertical pipe 5 and reduce the possibility of blockage.

[0039] The rubber strip 10 disposed on one side of the movable plate 7 close to the inner wall of the circulation part 2 is closely attached to the inner wall of the circulation part 2. The existence of the rubber strip 10 can further scrape off the sludge adhered to the inner wall of the circulation part 2, thereby improving the cleaning effect;

[0040] The cutting blade 11 is fixed on the movable plate 7 and works with the rotation of the movable plate 7. When the sludge passes through the circulation part 2, the cutting blade 11 can effectively break up the large particles and fibers in the sludge to prevent them from blocking the circulation channel, which not only improves the fluidity of the sludge, but also reduces the blockage and dirt accumulation problems inside the pump body 1.

[0041] The circulation part 2, the vertical pipe 5, the ring 6, the movable plate 7 and the cutting blade 11 are all made of corrosion-resistant alloy material, which has good corrosion resistance and wear resistance and can resist the erosion of chemicals and particles in the sludge. At the same time, the polytetrafluoroethylene coating sprayed on their surfaces further enhances the anti-adhesion performance and reduces the accumulation and adhesion of sludge inside the pump body 1;

[0042] The sludge flow sensor arranged at the sewage outlet 4 can monitor the sludge flow in real time and feed the data back to the controller, so as to monitor and control the flow of the pump body 1 in real time.
