Pump body water inlet filtering and separating device

Abstract

The invention discloses a pump body water inlet filtering and separating device. The device comprises a barrel and an annular filter arranged in the barrel, a gap for containing impurities in water isformed between the barrel and the annular filter, a plurality of water inlets are formed in the peripheral side wall of the barrel, and a plurality of filtering holes for filtering the impurities inthe water are formed in the peripheral side wall of the annular filter so that the impurities can be filtered in the gap. Due to such arrangement, sewage enters from a water inlet in the barrel, impurities such as large-particle branches, stones and plastics in water are filtered in the gap through the annular filter, impurities are discharged from the lower end of the barrel and can not enter thepump body, the pump body can pump water normally, the working efficiency of the pump body is not influenced by work stop caused by impurity blockage, the pump body is protected from being blocked byimpurities to be damaged or burnt out, the cycle utilization rate of the pump body is effectively increased, and the problems that in the prior art, a sewage pump is prone to being blocked, the pump body cannot work normally, even the pump body is burnt out, pollution discharge is not smooth, and serious influences are brought to life and production are solved.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a filtering and separating device for a water inlet of a pump body. Background technique [0002] In daily production and life, people will produce a large amount of wastewater and sewage, so it is very common to use sewage pumps to transport urban sewage. However, since the sewage contains insoluble impurities such as large particles of leaves, branches, small plastics, and small stones, and the water inlet of the sewage pump base is relatively large, these insoluble impurities will enter the sewage pump from the water inlet during normal pumping work. If the pump body is blocked, the flow of water will not be smooth, the pump body will not work normally, and even the pump body will be burned or damaged, which will bring great inconvenience and loss to daily production. Therefore, how to solve the problem that the sewage pump in the prior art is easy to block, so that the p...
