Multi-stage membrane separation equipment

Abstract

The invention discloses multi-stage membrane separation equipment which structurally comprises a box body, a filter membrane, a first-stage hole and a water outlet, the inner side of the box body is movably clamped with the outer side of the filter membrane, the outer side of the first-stage hole is movably clamped with the inner side of the box body, and the water outlet is fixedly connected with the right end of the box body in an embedded mode. In the shaking process of a supporting block, flowing of water flow drives a blocking plate to rotate in a filtering frame through a connecting shaft to capture floccules, a buffer plate swings to a certain degree to increase the blocking area of a plate body in the capturing process, then the floccules are hooked through a hook head, the floccules are prevented from flowing to the filter membrane and the blocking effect is improved, and the filtering stage efficiency is improved. After the impact plate is impacted, a large amount of water contained in the storage cavity can be sprayed out towards the two sides when passing through the inclined opening, floccules originally flowing along the water flow are disturbed and prevented from directly flowing away from the holes, the blocking amount of the blocking plate is reduced, the service life of the blocking plate is prolonged, the contact area of the filter membrane and sewage is increased, and the filtering capacity is improved.

Description

technical field [0001] The invention belongs to the field of membrane separation equipment, and more specifically, relates to a multi-layer membrane separation equipment. Background technique [0002] Membrane separation equipment is a kind of water filtration equipment that separates water and impurities through membranes. It blocks impurities through the difference in diameter between water molecules and other impurities. In the process of sewage treatment in paper mills, sewage contains a large amount of Lignin and cellulose, so the sewage is purified in layers through multi-layer membrane separation equipment. During the purification process of sewage, flocculants will be added to gather fine fibers in the water, but because part of the flocs will pass along the direction of water flow The initial filter holes cause the surface of the subsequent filter membrane to be blocked by too much floc, which reduces the water flow of the filter holes and increases the filtration t...
