Folding filter core structure, filter cylinder device and machining method of filter cylinder device

Abstract

A folded filter element structure, a filter cartridge device and a processing method thereof, the folded filter element structure includes a filter element frame, the filter element frame is connected with a ring-shaped folded filter element, the lower end of the filter element frame is provided with a lower cover; the filter cartridge device includes a filter cartridge and a The pleated filter element structure; during processing, one or more materials in the nuclear pore fine filter membrane, non-woven fabric, and nuclear pore coarse filter membrane are compositely welded together, and folded or not folded in half along the width direction and placed in parallel, and then along the The stretching direction is folded into a louver shape, and its two ends are sealed and welded to form a ring-shaped folded filter element; the folded filter element is placed on the filter element frame, and then the upper and lower edges of the folded filter element are welded to the upper and lower covers to form a sealed body; put the sealed body Insert it into the frame of the filter cartridge so that the upper and lower covers fit closely with the inner wall of the frame of the filter cartridge. The filter element of the present invention is self-contained, easy to replace, low in production cost, long in service life, has increased effective filtering area of ​​the filter element, strong dirt holding capacity, improved filtering efficiency, reduced replacement frequency, more convenient use and wide application range.

Description

technical field [0001] The invention relates to the technical field of water purification and filtration, in particular to a folded filter element structure, a filter cartridge device and a processing method thereof. Background technique [0002] Water is the source of life. Nutrients are transported to various organs and skin of the human body through water, and metabolites in the body are excreted by water. Water is the most basic substance for the expression of vital signs. Drinking water reasonably can not only strengthen the body, refresh the mind, and increase intelligence, but also prevent aging, prolong life, beautify, and detoxify. [0003] Boiled and naturally cooled boiled water has the functions of promoting metabolism, transporting nutrients, cleaning internal organs, diuresis and laxative, and enhancing the body's immunity. The boiled water kills the pathogenic bacteria during the boiling process, and retains calcium, magnesium, phosphorus and other macro and ...

AI Technical Summary

Problems solved by technology

Due to the limitations of the multi-layer structure of the material itself, deep filter materials often have uneven pore sizes, and it is difficult to obtain accurate filtration accuracy; when filtering, it is necessary to intercept particles by blocking layers of materials under the action of external forces, and the filtration resistance is large. , low filtration efficiency, high energy consumption, and frequent replacement of filter elements; in addition, due to the maze-like porosity of the material, it has strong water absorption capacity, and the material is often in a wet state, which is very easy to breed harmful substances such as bacteria and parasites

Therefore, the secondary pollution of this type of material is extremely serious
