Problems solved by technology

However, the structural stability of the braided support net and the size of the mesh are contradictory. To improve the structural stability of the support net, the size of the mesh must be reduced, and the reduction of the mesh size will affect the fluid flow. Relatively large flow resistance; in order to reduce the flow resistance of the fluid, increase the distance between the yarns, thereby increasing the mesh size, which will cause the structural stability of the support network to deteriorate

Abstract

The invention provides a folding filter element, which comprises a center rod and a filter membrane arranged on the periphery of the center rod, the filter membrane is folded to form folds, supportingnets are arranged on the upstream side and the downstream side of the filter membrane, the supporting nets are formed by warp yarns and weft yarns which are perpendicular to each other, the warp yarns are provided with intervals that are different in size and are distributed at a fixed frequency, and the warp yarns with small intervals are tight in arrangement. The plurality of warp yarns which are arranged closely are mutually reinforced in action, the warp yarns and the weft yarns together provide necessary structural stability for the supporting nets, the adjacent warp yarns with large intervals and the adjacent weft yarns together form large meshes, and the large meshes cause small resistance to fluid flowing, so that fluid can pass through the meshes conveniently. Moreover, the extending directions of the warp yarns are perpendicular to the extending directions of the pleat peaks, flow channels with different widths are formed among the warp yarns, and the extending directions ofthe flow channels are parallel to the flowing direction of the fluid, so that the speed of the fluid passing through the supporting nets is further increased, and the filtering rate of the filter element is increased.

Description

Technical field[0001]The present invention relates to the technical field of filtration, in particular to a pleated filter element, and more specifically, to a pleated filter element provided with a support net on the upstream side and / or downstream side of the filter membrane.Background technique[0002]Pleated filter membranes are widely used in fluid filtration and purification. In practical applications, support nets are usually set on both sides of the filter membrane. After the support nets are folded together with the filter membrane to form pleats, they are installed between the center rod and the shell. , Forming a folded filter element. The support net can protect the filter membrane during the folding and installation process, and reduce the damage of the folding machine to the filter membrane; in the final folded filter element product, the support net separates the surface of the filter membrane to form a certain gap between the pleat surfaces. The formation of fluid flow...
