Liquid impurity separation device

Abstract

The invention discloses a liquid impurity separation device which comprises a liquid incoming trench, a transmission wheel and a filter cloth cleaning mechanism. An input pipe for delivering liquid waiting for impurity removal to the liquid incoming trench is arranged above the liquid incoming trench, an opening is formed at the bottom of the liquid incoming trench, and annular filter cloth covers the bottom of the liquid incoming trench; the transmission wheel is supported in the annular filter cloth and used for driving the same to rotate to enable the same to move along the bottom of the liquid incoming trench constantly, and the filter cloth cleaning mechanism is used for cleaning impurities of a portion, not corresponding to the bottom of the liquid incoming trench, of the filter cloth in the process when the filter cloth rotates. The filter cloth constantly rotates under action of the transmission wheel to enable a portion, corresponding to the liquid incoming trench, of the filter cloth to perform filtering while a portion, away from the liquid incoming trench, of the filter cloth to perform cleaning under action of the filter cloth cleaning mechanism, so that filtering and cleaning are realized at the same time, the filter cloth can be cleaned without stopping, continuous liquid impurity removal is facilitated, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of machinery industry, more specifically, to a liquid impurity separation device. Background technique [0002] In the prior art, liquids such as domestic wastewater and industrial wastewater need to undergo impurity removal treatment before they can be discharged or subsequently utilized. [0003] However, currently commonly used liquid impurity removal devices generally include filter cloth, and after a long period of use, the filter cloth is contaminated with impurities, and the liquid impurity removal device needs to be shut down to clean the filter cloth, which affects the process of liquid impurity removal. [0004] To sum up, how to provide a device for removing impurities in liquid so as to avoid shutting down the device to clean the filter cloth is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0005] In view of this, the present invention provi...
