Description

Technical Field

[0001] This utility model relates to the field of sewage pump technology, specifically a submersible sewage pump. Background Technology

[0002] Submersible sewage pumps are specially designed pumps primarily used for drawing and discharging sewage and wastewater. They operate by using an electric motor to drive an impeller within the pump body, creating negative pressure that draws liquid into the pump and discharges it through the outlet. During transport, submersible sewage pumps often encounter impurities, sludge, plastic bags, and long fibers. These substances can easily become entangled on the pump blades or main shaft, potentially causing the motor to stall or even burn out, and adversely affecting the pipeline or the pump itself. Utility Model Content

[0003] The purpose of this utility model is to provide a submersible sewage pump to solve the problem mentioned in the background art that, during the transportation process, submersible sewage pumps often encounter impurities, sludge, plastic bags, long fibers, and other substances. These substances can easily become entangled on the pump blades or main shaft, which may cause the motor to stall, or even lead to burnout accidents in severe cases, and have adverse effects on the pipeline or pump body itself.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a submersible sewage pump, comprising a connecting cylinder, a pump body fixedly connected to the bottom of the connecting cylinder, a connecting shaft rotatably connected inside the connecting cylinder, an impeller fixedly connected to the bottom end of the connecting shaft, the impeller rotatably connected to the pump body, a rotating rod fixedly connected to the bottom of the impeller, a plurality of No. 1 crushing blades fixedly connected at equal intervals to the outer side of the rotating rod, a bottom suction pipe fixedly connected to the bottom of the pump body, a plurality of No. 2 crushing blades cooperating with the bottom suction pipe fixedly connected at equal intervals to the inner side of the bottom suction pipe, a rotating seat fixedly connected to the bottom end of the rotating rod, a plurality of No. 4 crushing blades fixedly connected at equal intervals to the outer side of the rotating seat, a fixed sleeve rotatably connected to the outer side of the rotating rod, the bottom of the fixed sleeve rotatably connected to the rotating seat, and a plurality of No. 3 crushing blades cooperating with the No. 4 crushing blades fixedly connected at equal intervals to the outer side of the fixed sleeve.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 3 This utility model provides a technical solution: a submersible sewage pump, including a connecting cylinder 1, a pump body 6 fixedly connected to the bottom of the connecting cylinder 1, a connecting shaft 3 rotatably connected inside the connecting cylinder 1, an impeller 7 fixedly connected to the bottom end of the connecting shaft 3, the impeller 7 being rotatably connected to the pump body 6, a rotating rod 8 fixedly connected to the bottom of the impeller 7, a plurality of first-order crushing blades 9 fixedly connected at equal intervals to the outer side of the rotating rod 8, a bottom pumping pipe 11 fixedly connected to the bottom of the pump body 6, and a plurality of second-order crushing blades 10, which cooperate with the bottom pumping pipe 11, fixedly connected at equal intervals to the inner side of the bottom pumping pipe 11. A rotating seat 16 is fixedly connected to the bottom end of the rotating rod 8. Multiple No. 4 crushing blades 17 are fixedly connected at equal intervals on the outer side of the rotating seat 16. A fixed sleeve 14 is rotatably connected to the outer side of the rotating rod 8. The bottom of the fixed sleeve 14 is rotatably connected to the rotating seat 16. Multiple No. 3 crushing blades 15 that cooperate with the No. 4 crushing blades 17 are fixedly connected at equal intervals on the outer side of the fixed sleeve 14. The No. 4 crushing blades 17 rotate and cooperate with the No. 3 crushing blades 15 to crush impurities, sludge, plastic bags and long fibrous materials present in the sludge pumped into the sludge through the support seat 19.

[0017] The rotating seat 16 has a fixedly connected crushing disc 18 at its bottom. When the rotating seat 16 rotates, it drives the fourth crushing blade 17 on the outside to rotate. The rotating seat 16 also drives the crushing disc 18 at the bottom to rotate, thus crushing the impurities, sludge, plastic bags and long fibrous materials that enter.

[0018] The outer support sleeve 12 is rotatably connected to the outer side of the rotating rod 8. The bottom of the outer support sleeve 12 is rotatably connected to the fixed sleeve 14. Multiple outer fixing brackets 13 are equidistantly fixed to the outer side of the outer support sleeve 12. The outer side of the outer fixing brackets 13 is fixedly connected to the support base 19. The outer support sleeve 12 and the outer fixing brackets 13 are fixed inside the support base 19. The outer support sleeve 12 supports the fixed sleeve 14 and the rotating rod 8. The fixed sleeve 14 rotates at the bottom of the outer support sleeve 12, which improves the working stability.

[0019] The pump body 6 is fixedly connected to a discharge pipe 5 on one side, through which sludge is extracted.

[0020] The outer side of the connecting cylinder 1 is fixedly connected to a support plate 4, and the discharge pipe 5 is fixedly connected to the support plate 4. The support plate 4 provides support for the overall position.

[0021] The support plate 4 has a drive motor 2 installed on its top. The output end of the drive motor 2 is fixedly connected to the connecting shaft 3. The output end of the drive motor 2 drives the connecting shaft 3 to rotate, thereby completing the overall rotation of the impeller 7 and the rotating rod 8.

[0022] Specifically, during use, the output end of the drive motor 2 drives the connecting shaft 3 to rotate. When the connecting shaft 3 rotates, it drives the impeller 7 to rotate, and the impeller 7 draws in the sludge through the support base 19 and the bottom pumping pipe 11. When the impeller 7 rotates, it drives the rotating rod 8 at the bottom to rotate synchronously. When the rotating rod 8 rotates, it drives the first crushing blade 9 on the outside to rotate. At the same time, the rotating rod 8 drives the rotating base 16, the fourth crushing blade 17 and the crushing disc 18 to rotate synchronously, which crushes the impurities, silt, plastic bags and long fiber materials in the sludge drawn into the support base 19. After crushing, entanglement and blockage are avoided. At the same time, the first crushing blade 9 and the second crushing blade 10 cooperate to further crush the impurities, silt, plastic bags and long fiber materials in the sludge entering the bottom pumping pipe 11.
