A solid-liquid separation non-clogging pump

Abstract

The present invention designs a solid-liquid separation non-clogging pump, which includes a solid particle separator arranged sequentially from top to bottom, a small particle crushing chamber (left chamber), wherein the small particle chamber has a built-in spiral crushing device and a conical crushing device, Large particle crushing chamber (right chamber), in which the large particle crushing chamber has built-in front impeller, umbrella crushing device, spiral crushing device and conical crushing device, two-chamber partition, bracket, particle conveying device, front impeller, Conical flow channel, first-stage volute, first-stage impeller, and 6 "back"-shaped crushing devices installed between the first-stage volute and impeller, second-stage volute, second-stage impeller, and second-stage volute and There are 12 "back" shaped crushing devices installed between the impellers. The solid-liquid separation type non-clogging pump of the present invention realizes the separation, crushing and transmission of large particles and small particles before entering the pump, as well as the crushing of residual particles and air bubbles in the pump, and each "back" shaped crushing device can The blades rotate for 7 times in one cycle, which greatly enhances the crushing capacity, reduces the probability of cavitation, and reduces the occurrence of clogging.

Description

technical field [0001] The invention relates to the technical field of non-clogging pumps, in particular to a solid-liquid separation type non-clogging pump. Background technique [0002] Pumps are widely used in fluid transportation, agricultural irrigation and other fields. However, when the pump is transporting solid-liquid two-phase flow, it often encounters the accumulation of solid particles, which will accumulate for a long time and cause blockage, which not only increases energy consumption, but also makes the pump unable to operate normally in severe cases. The cavitation problem caused by bubbles in the water during the operation of the pump destroys the pump components, resulting in reduced efficiency, shortened pump life, noise and vibration. SUMMARY OF THE INVENTION [0003] In view of the deficiencies in the prior art, the present invention provides a solid-liquid separation type non-clogging pump. The device is provided with a large particle and small parti...

Problems solved by technology

However, the pump often encounters the accumulation of solid particles when conveying solid-liquid two-phase flow, and the long-term accumulation leads to blockage, which not only increases energy consumption, but also makes the pump unable to operate normally

During the operation of the pump, the cavitation problem caused by air bubbles in the water damages the pump components, resulting in reduced efficiency, shortened service life of the pump, and noise and vibration
