Automatic stirring non-clogging sludge pump

Abstract

The invention relates to an automatic stirring non-clogging sludge pump, and solves the problem that a water inlet is easy to clog in the prior art. According to the technical scheme, a hub of an impeller is conical, the small end of the hub passes through the water inlet, an extension section is arranged outside a shell, blades of the impeller are spiral centrifugal blades, the blades spirally wind and extend from one end of the hub to the other end of the hub, and each blade is provided with the extension section outside the shell. The automatic stirring non-clogging sludge pump has the effects that the special structure of the impeller (the impeller has functions of the impeller of the sludge pump, and the extension sections of the impeller extending from the water inlet have a functionof stirring sludge and silt) can form the extension sections outside the water inlet of a pump body, and the extension sections have effects of a stirring impeller, so that the purpose of stirring the sludge and the silt is achieved, and the sludge and the silt are prevented from clogging the water inlet; and the spiral centrifugal blades are adopted, so that the sludge and silt stirring effect can be improved, and the working efficiency of the sludge pump is improved.

Description

Technical field [0001] The present invention relates to a sofa, in particular, involving an automatic stirring without clogging and mutacitive pump. Background technique [0002] Fish pond, sandstone, etc., sewage pumps, applied to these places, for a long time, the water inlet of the sewage pump is easy to be mud, sediment dilled, sludge, sediment, blockage Inlet, leading to water. Conventional sewage pump uses solutions: extending pump shafts, extends the pump shaft to the pump body, and a stirovers are fitted outside the pump body. The problem of such structural sewage pumps: 1, the mixture has been used for a long time, easy to worn and easy to fall. 2, the assembly is relatively complex, production, assembly efficiency is low, high cost, is not convenient for maintenance. 3, the inner wall of the pump body is smooth inner wall, and the impeller and the pump body are only in the gap, the sediment is easy to pass the gap between the impeller and the pump body, causing the impe...

AI Technical Summary

Problems solved by technology

The problems of the sewage pump with this structure: 1. The mixing blade has been used for a long time, and it is easy to wear and fall off

2. The assembly is more complicated, the production and assembly efficiency is low, the cost is high, and it is not easy to maintain and repair

3. The inner wall of the pump body is smooth, and the gap between the impeller and the pump body is only a gap fit. The sediment is easily stuck in the gap between the impeller and the pump body, causing the impeller to be stuck, and the sewage pump cannot be used normally.

4. The impeller of the sewage pump has relatively weak wear resistance, is easy to wear and has weak cutting ability
