Axial flow pump for sewage treatment equipment

Abstract

The invention discloses an axial flow pump for sewage treatment equipment. The axial flow pump comprises an axial flow pump body, wherein one and the same fixing rod is fixedly mounted on the inner walls of two sides of the axial flow pump; a rotating rod is rotationally mounted on the top side of the fixing rod; a placing frame is fixedly mounted at the top end of the rotating rod; a fixing frameis fixedly mounted on the top side of the axial flow pump body; a rotating motor is fixedly mounted on the inner wall of the top side of the fixing frame; a rotating shaft is fixedly mounted on an output shaft of the rotating motor through a coupling; the bottom end of the rotating shaft extends into the placing frame positioned in the axial flow pump body; a rotating groove is formed in the inner wall of the bottom side of the placing frame; and the bottom end of the rotating shaft is rotationally mounted in the rotating groove. The axial flow pump disclosed by the invention is reasonable instructural design and convenient to use; pollutant accumulating on the inner walls of two sides of the axial flow pump can be cleared; the blockage phenomenon of the axial flow pump can be effectively relieved; and accordingly, the working efficiency of the axial flow pump can be improved and the usage demand of a user can be met.

Description

technical field [0001] The invention relates to the technical field of axial flow pumps, in particular to an axial flow pump for sewage treatment equipment. Background technique [0002] The impeller of the axial flow pump is equipped with 2 to 7 blades, which rotate in the cylindrical pump casing. The pump casing above the impeller is equipped with fixed guide vanes to eliminate the rotational movement of the liquid and change it into axial movement. The kinetic energy of rotary motion is converted into pressure energy. Axial flow pumps are usually single-stage, and a few are made of two-stage. [0003] The patent with the publication number CN202209279U discloses a durable axial flow pump. The components of the axial flow pump have the characteristics of wear resistance, corrosion resistance, and high temperature resistance, making the entire axial flow pump more durable. However, the durable axial flow pump is used During sewage treatment, since the sewage passes through...

[0003] The patent with the publication number CN202209279U discloses a durable axial flow pump. The components of the axial flow pump have the characteristics of wear resistance, corrosion resistance, and high temperature resistance, making the entire axial flow pump more durable. However, the durable axial flow pump is used During sewage treatment, since the sewage passes through the axial flow pump, a large amount of pollutants will accumulate, and long-term use will easily lead to blockage of the axial flow pump, and there is room for improvement. Therefore, we provide an axial flow pump for sewage treatment equipment , the device has a reasonable structural design and is easy to use. It can clean the pollutants accumulated on the inner walls of both sides of the axial flow pump, effectively alleviate the clogging of the axial flow pump, thereby improving the working efficiency of the axial flow pump and meeting the needs of users. user needs
