Filter membrane support and filter device

Abstract

The present invention provides a filter membrane holder and a filter device. The filter membrane holder comprises a filter portion, a support portion and a sealing plate. The filter portion includes a plurality of sequentially stacked laminations, and a gap for the flow of fluid is provided between every adjacent two laminations. Two ends of each of the laminations in the filter portion are fixedly connected to the support portion to form a holder body and a clear water chamber for the pass of the fluid is arranged at the interior of the holder body. The sealing plate is arranged at one end of the holder body. According to the filter membrane holder provided by the invention, the fluid only passes the side where the filter portions are arranged, and the area where the fluid passes the filter membrane holder is reduced, so that the speed of the fluid in the gaps is increased, the laminations produce a strong vibration, at the same time, a reciprocal flow of the fluid among the gaps is also enhanced, the combined effects can strengthen the effect of the filter membrane at the set distance of the outside of the filter membrane holder, and a self-cleaning function of the filter membrane is improved.

Description

technical field [0001] The invention relates to a filter device in the field of fluid component filtration, separation and purification, in particular to a filter membrane support and a filter device with the filter membrane support. Background technique [0002] At present, in the prior art, a plurality of gaps are provided on the outer peripheral surface of the filter membrane support, and the fluid enters the clear water chamber of the filter membrane support through the gaps, and the flow rate of the fluid passing through the gap is relatively small. After the filter membrane is formed, the lamination The vibration is small, and the movement of the particles in the filter membrane is weak. After the thickness of the filter membrane is increased, the self-cleaning effect of the filter membrane is not good, and the filtration efficiency of the filter membrane is poor. Contents of the invention [0003] In order to solve the above technical problems, an object of the pres...
