Supporting plate used for filtering element, and filtering element

Abstract

The invention relates to a supporting plate used for a filtering element, and the filtering element. The supporting plate comprises a main body and a frame; the main body is surrounded by the frame; the main body comprises an A surface and a B surface; the A surface is composed of a plurality of support assemblies arranged in a compact manner, and the support assemblies are composed of geometric figure shaped supports; the B surface is composed of a plurality of support assemblies arranged in a compact manner, and the support assemblies are composed of geometric figure shaped supports; and flow guide grooves of the filtering element are pores formed through crossed combination of the supports of the A surface and the supports of the B surface; the filtering element is composed of the supporting plate composed of the plurality of the geometric figure shaped supports arranged in a compact manner, and at least two surfaces of flat microfiltration membrane. The rigidity of the supporting plate is increased, the weight of the supporting plate is reduced, the cost of the supporting plate is reduced; the geometric figure shaped supports of the A surface and the B surface can be different,and can be the same, and are arranged in a staggered manner; and the water outlet flux of the filtering element is increased.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a support plate for a filter element and a filter element thereof. Background technique [0002] The support plate is an important core component of the filter element. Since the invention, the structure and formation of the supporting plate are basically the same. Most of them are thin plates made of engineering plastics, and there are longitudinal guide grooves on the front and back. This support plate has the following disadvantages in actual use: first, the relatively thick support plate (5.5-6mm), its cost accounts for about 40-50% of the entire membrane element; second, the large-area membrane element is positioned on the side (Insert into the U-shaped groove) to maintain the required spacing of the components (usually 7-8mm). For such a large plane, even such a thick plastic support plate is only positioned on both sides, and deformation will inevitably occur in a...

This support plate has the following disadvantages in actual use: first, the relatively thick support plate (5.5-6mm), its cost accounts for about 40-50% of the entire membrane element; second, the large-area membrane element is positioned on the side (Insert into the U-shaped groove) to maintain the required spacing of the components (usually 7-8mm). For such a large plane, even such a thick plastic support plate is only positioned on both sides, and deformation will inevitably occur in actual use. Warping, deformation and warping will cause the distance between two adjacent membrane elements to change at the warping position, especially if the distance becomes smaller, it will cause uneven air and water washing between the membrane elements, resulting in mud accumulation, which will cause blockage of the membrane surface and make the outlet water pass through. drop in volume
