Description

Technical Field

[0001] The utility model relates to the technical field of sewage pumps, in particular to a sewage pump with an anti-blocking structure. Background Art

[0002] A sewage pump is a device specifically designed to transfer sewage from one place to another. It is usually used for the discharge and transfer of sewage, wastewater or other liquids, and is widely used in urban sewage treatment plants, industrial production, sewage collection systems, and sewage treatment in rural areas, etc. Chinese Patent No. CN216241355U discloses a horizontal sewage pump. On the one hand, a submersible motor is assembled to adapt to the use in harsh environments with high humidity and easy flooding. On the other hand, a double-blade open impeller is set, which can effectively transport media containing a certain amount of solid particles and reduce the probability of blockage during sewage discharge. However, in the actual use process of the sewage pump, it not only contains solid particles but also is mixed with sundries (fallen leaves, plastic bags, etc.), and it is still very easy to cause the sewage pump to be blocked, affecting the use effect and service life of the entire sewage pump, and improvement is needed. Content of the Utility Model

[0028] Working principle: For a sewage pump with an anti-blocking structure of the present utility model, during use, the water inlet pipe 15 is connected to an external water inlet pipe, and the drain pipe 4 is connected to an external drain pipe. The motor 2 is started through an external power supply. The motor 2 drives the pump body 3 to work through a driving rod, realizing the pumping work. The motor 2 also drives the large grooved pulley 5 to rotate through the driving rod. The large grooved pulley 5 drives the small grooved pulley 6 to rotate through the belt 7. The small grooved pulley 6 drives the first bevel gear 11 to rotate through the driven rod 8. The driven rod 8 rotates in the inner cavity of the bearing 10. The first bevel gear 11 drives the second bevel gear 12 to rotate. The second bevel gear 12 drives the first spur gear 19 to rotate through the first rotating rod 16. The first spur gear 19 drives the second spur gear 20 meshing with it to rotate. The second spur gear 20 drives the second rotating rod 17 to rotate. The first rotating rod 16 and the second rotating rod 17 respectively drive the adjacent crushing knives 18 to rotate. Sewage enters the inner cavity of the treatment box 13 from the water inlet pipe 15. When inhaling larger debris, the rotating crushing knives 18 crush the debris, thus avoiding the situation of blockage of the sewage pump;

[0029] When the motor 2 of the device is working, it can not only drive the pump body 3 to pump water, but also drive the crushing knife 18 to rotate. The crushing knife 18 crushes the sundries with a larger suction volume, thus avoiding the blockage of the sewage pump, killing two birds with one stone, and ensuring the normal operation of the sewage pump.
