Coupling filter material replacement biological filter

Abstract

The invention discloses a coupling filter material replacement biological filter which structurally comprises a filter cartridge, a base and a connector, the bottom of the filter cartridge is fixedlyembedded in the upper surface of the base, and the bottom of the connector is connected to the top of the filter cartridge in a welded mode. Sewage flows from top to bottom under action of gravity sothat the sewage and impurities in the sewage flow into an isolation block through a filter screen to isolate the impurities in a storage cavity, a rotating roller rotates under the impact of water flow, and meanwhile, a sliding rod penetrates through a through hole to extrude a spring, so that the rotating roller vibrates back and forth to prevent the impurities from flowing out, the sewage is conveniently filtered, and under the effects of supporting of the supporting blocks and outward pushing of the moving rods and the sliding blocks by the supporting springs, the rubber blocks are tightlyattached to the inner walls of the inserting holes, so that the inner walls of the inserting holes are conveniently cleaned, and impurities are prevented from entering the inner walls of the insertingholes to influence the installation of the filter elements.

Description

technical field [0001] The invention relates to the field of biological filter equipment, in particular to a biological filter for replacing coupling filter materials. Background technique [0002] Coupling filter material replacement biological filter is a process of replacement and filtration through the interaction of two substances. There is a filter layer inside it, so that the sewage can pass through the filter from top to bottom under the action of gravity after entering the filter. Layers are filtered, and at the same time, the coupling organisms in the filter are used to purify the water quality. [0003] At present, there is an existing coupling filter material replacement biological filter machine. After the sewage is filtered, the impurities in the sewage are filtered in the filter. Since the coupling filter material in the filter element gradually reduces the coupling organisms after the water is purified, making The coupling filter material needs to be replace...

AI Technical Summary

Problems solved by technology

[0003] At present, there is an existing coupling filter material replacement biological filter machine. After the sewage is filtered, the impurities in the sewage are filtered in the filter. Since the coupling filter material in the filter element gradually reduces the coupling organisms after the water is purified, making The coupling filter material needs to be replaced, and when the filter element is pulled out, the filtered impurities enter the filter element socket, causing the filter element socket to be filled with impurities, which affects the installation of the filter element
