Abstract
The utility model belongs to the technical field of polishing solution processing, and particularly relates to a polishing solution backflow impurity removal device which comprises a box body and an air pump. A partition piece is arranged in the box body, and a plurality of filter holes are formed in the partition piece in a penetrating manner; the interior of the box body is divided into a filtering cavity and a filtrate storage cavity by the partition piece; a plurality of filter materials are accommodated in the filter cavity, and gaps are formed among the plurality of filter materials and are used for accommodating impurities in the mixed stock solution; an inflating channel and an exhaust hole are formed in the box body; the inflating channel is used for communicating the air pump with the filtering cavity; gas pumped out of the pumping channel can disturb the mixed stock solution in the filtering cavity, so that impurities in the gaps are turned over, accumulation of the impurities in the gaps is reduced, blockage of the impurities is reduced, and the cleaning times and frequency of a filtering material are reduced; besides, the rising bubbles can enable the mixed stock solution to form circulating reflux, so that the mixed stock solution passes through the filter materials in a reciprocating manner and then is discharged, the filtration is more sufficient, and a better filtration effect is achieved.
