Description

Technical Field

[0001] The utility model belongs to the technical field of filters, and particularly relates to an integrated filter housing. Background Art

[0002] A filter housing is the outer shell that surrounds the filter element in a filtration system. It protects the filter element and ensures the stability of the filter media during the filtration process. Filter housings are typically made of stainless steel or other durable materials, capable of withstanding certain pressures and temperatures, ensuring the stability and durability of the filter element during the filtration process. The design and material selection of the filter housing have a significant impact on its performance. Currently, most filter elements on the market are simple mechanically enclosed housings with simple external inlet and outlet ports, housing the filter element to filter the incoming media. However, they lack any control or sensing capabilities for the filtered media, meaning they lack automated control capabilities. To achieve control of the filter media, the piping system must be redesigned, with additional valves and sensors added to the exterior of the filter housing. While this can achieve some desired functionality, it results in an excessively large device with numerous interfaces and piping, significantly increasing its complexity, poor overall integrity, and a less attractive appearance.
