Abstract

The invention discloses a submersible pump device with a filtering function. Particularly, the submersible pump device is capable of filtering water and provided with an anti-blocking mechanism, a filter is effectively prevented from being blocked, and the problem that a filtering part in an existing submersible pump is blocked after long-time use is solved. A driving motor is installed on an upper flange of a device body. A pump body is fixedly connected to the lower portion of the driving motor. The filter is fixed below the pump body. An impeller is rotationally arranged in the pump body and is fixed to a rotating shaft connected to the output end of the driving motor. The upper portion of the filter communicates with the lower portion of the pump body through a through pipe. A drainagepipe is fixed to the side wall of the pump body in a communicating mode. An anti-blocking mechanism is arranged at the lower end of the rotating shaft. A filtering plate is fixedly connected to an inner wall of the lower portion of the filter. A plurality of filtering holes used for filtering the water liquid are uniformly formed in the surface of the filtering plate.

Description

technical field [0001] The invention relates to a water supply device, in particular to a submersible pump device with filtering function. Background technique [0002] The working principle of the pump is roughly the same. The impeller rotates at a high speed, and the liquid in it rotates with the blades. Under the action of centrifugal force, it flies away from the impeller and shoots outward. The speed of the injected liquid gradually slows down in the diffusion chamber of the pump casing, and the pressure gradually increases. Then from the pump outlet, the discharge pipe flows out. [0003] When the submersible pump is in the water, it is inevitable that there will be sediment. Therefore, most of the submersible pumps are equipped with a filter cover at the inlet below the submersible pump. The filter hole on the cover causes the problem of poor pumping and drainage. Contents of the invention [0004] Based on the deficiencies in the prior art mentioned in the backgr...
