A composite filter MBR membrane sheet assembly

Abstract

The utility model provides a kind of composite filtering MBR membrane piece assembly, including pool body, support, the middle part of the inside of pool body is fixedly connected with support;The inside of the support is detachably connected with crossbeam by connecting piece, and the membrane piece is connected between the crossbeam;The membrane piece is composed of numerous membrane filaments.The utility model has the advantages that lifting beam, joint, movable head are integrated, and the lifting of movable head can be realized by practical hand wheel rotating screw rod, so as to realize the lifting of lifting beam, since membrane piece bottom is fixed, the tightness adjustment of membrane piece can be realized by pulling steel wire, after long time use, its surface will relax due to accumulation, gravity effect, such structure design can keep membrane piece with constant tension, solve the problem of shaking or accumulation caused by membrane filament relaxation due to long-term operation, prolong the life of membrane;When maintaining, without special tool and shutdown, manual rotation hand wheel second can complete the tensioning adjustment of all membranes.
