technical field

The utility model relates to a filter core, in particular to a microporous folded filter core.

Background technique

Folded filter elements are widely used in the current market. The filter elements currently on the market are mainly composed of shells, end caps, filter membranes and sockets. When the filter membrane is filtering, impurities in the liquid will be adsorbed on the surface of the filter membrane. There are more and more impurities on the surface of the filter membrane, which can block the micropores on the filter membrane, causing the filter membrane to fail to complete liquid filtration. In view of the above defects, it is necessary to design a microporous folded filter element.

Compared with the prior art, the microporous pleated filter element first connects the water inlet joint to the water pipe, and the water enters the microporous membrane inside the pipe body from the water inlet joint, and the water is filtered through the microporous membrane. The water flows into the water outlet hole at the lower end of the microporous membrane, and then flows into the water outlet joint through the water hole, and then the water is discharged from the water outlet joint. When the water enters the micro-filtration membrane from the water inlet joint, the water will rush to the impeller. The momentum of the water flow can make the impeller drive the rotating shaft to rotate, so that the brush rotates together. When the brush rotates, it will rub against the microporous membrane, so the impurities on the microporous membrane can be cleaned, so as to prevent the impurities from destroying the micropores. The filter hole of the filter membrane is blocked. The filter element has a simple structure and powerful function, which can realize high-precision filtration of the impeller, and at the same time prevent impurities from clogging the microporous filter membrane, so that the filter element can be used normally for a long time.
