Problems solved by technology

The defect of this fixed-point structure by welding is that when the membrane is installed on the filter medium, the outer surface of the membrane element is under great pressure, and the mechanical strength is the weakest in the middle of the two supporting points of the support ring. When the membrane is under force, a bending moment is generated from the weak point to the supporting point, so that the large pollutants in the treated medium also pass through the membrane, which makes the filtration accuracy drop significantly. Sometimes the membrane extends along the bending surface, making the membrane The porosity increases, causing the membrane element to be scrapped

Abstract

The invention discloses a general filtering core assembly with a filtering membrane or a specific structure mode of the general filtering core assembly with the filtering membrane. The general filtering core assembly is characterized in that a cylindrical spiral supporting spring is adopted as a middle supporting body, two ends of the cylindrical spiral supporting spring are respectively provided with a filtering core head part and a filtering core end sealing cover, the supporting spring is fenced between the filtering core head part and the filtering core end sealing cover by a circle of supporting rods so as to form a filtering core skeleton, then the fencing outer surface of the filtering core skeleton is provided with filtering membrane diaphragm so as to combine into the filtering core assembly with a filtering membrane which is thick enough, and therefore the filtering membrane and filtering core assembly which is generally called as the filtering core is formed in structure.

Description

technical field [0001] The invention relates to a general filter membrane filter element assembly, or a specific structure of the universal filter membrane filter element assembly. This general filter membrane element assembly can achieve the filtration of media such as air, water and oil even under extremely low pressure. It is widely used in urban and rural areas, industrial and agricultural sewage treatment and advanced water treatment, as well as beer, Hygienic and clean treatment of water, filtration of various gases. It replaces the traditional paper folded filter element in air filter, gas filter, oil filter, fuel filter and air conditioner filter, which belongs to membrane structure and membrane filtration technology. Background technique [0002] Most of the currently used filter element elements of the filter membrane adopt a welded structure, that is, at the head and tail of the filter element of the filter membrane, there are multiple iron wires of equal length ...
