A tea wine filtering and clarifying equipment based on membrane filtering and CO2 pulse self-cleaning

Abstract

The utility model relates to tea wine processing equipment technical field especially based on membrane filter, CO2 pulse self -cleaning combined tea wine filter clarification equipment, including container, liquid feeding equipment, rotary power source, pulse jet component, the pulse jet component can interval time t to the container inside jet, the container rotation is connected with the support pivot of transmission of rotary power source, the part of support pivot is installed in the container inside interval arrangement filter disc, the support pivot has the passageway and is located one end of container outside open, the filter disc has the filter flow channel of communication with passageway. The equipment makes high pressure liquid to be subjected to shearing disturbance continuously in the filtering process, thereby effectively slows down the deposition of impurity on the surface of filter disc, through the micro -explosion impact effect formed by gas expansion, can high -efficiently strip the tea polyphenol gel layer and other pollutants attached to the surface of filter disc, realizes dynamic self -cleaning, improves the filtering efficiency and operation continuity.
