Description

Technical Field

[0001] This utility model relates to the field of filter membrane technology, specifically a filter membrane core structure. Background Technology

[0002] With the rapid development and application of advanced technologies, the requirements for fluids in both domestic and industrial production are becoming increasingly stringent, especially in industries such as water treatment, chemicals, pharmaceuticals, and food. Liquid filters are an indispensable device in pipelines transporting media. They are typically installed at the inlet of pressure reducing valves, relief valves, level control valves, or other equipment to remove impurities from the media, thus protecting the valves and equipment for normal operation.

[0003] When fluid enters the filter cartridge containing a filter screen of a certain size, impurities are blocked, while the clean filtrate is discharged from the filter outlet. The filter element is the impurity filtration component of the liquid filter. Currently, conventional filter element products all use filter elements for filtration, which causes the filtration effect to deteriorate and become clogged after a period of use. It is necessary to completely disassemble the filter device and remove the filter element for cleaning. Completely disassembling the filter device makes cleaning the filter element very cumbersome.
