PP filter core

Abstract

The invention discloses a PP (polypropylene) filter core, which comprises a cylindrical PP filter core body and filter core end covers covering two ends of the PP filter core body, and also includes a layer of cylindrical grid frame arranged on the inner wall of the PP filter core body. The outer wall of the PP filter core body is also provided with a layer of non-woven fabric. For the PP filter core provided by the invention, a layer of grid skeleton is added on the inner wall of the PP filter core body to support the PP filter core body, thus further enhancing the structural strength and surface pressure resistance of the PP filter core. Under the continuous impact of a fluid, the PP filter core is hard to deform, and has a prolonged service life and improved fluid filtration effect. With the characteristics of easy realization, low cost, as well as good effect, the PP filter core has good application prospects.

Description

technical field [0001] The invention specifically relates to a PP filter element, which belongs to a fluid purification device. Background technique [0002] At present, the PP filter element (also known as the melt-blown filter element) is made of non-toxic and tasteless polypropylene as a raw material, and the filter material is made by heating and melting, spraying, pulling, receiving and forming, which can effectively remove suspended solids, particles, and rust in the liquid. When the fluid enters the PP filter element with a filter of a certain specification, the impurities are blocked, and the clean flow flows out. It has been widely used in the waste water recycling industry. During use, the PP filter element needs to withstand the fluid for a long time. Therefore, the surface pressure resistance and structural strength of the PP filter element are high. The existing PP filter element has a low structural strength. Under the continuous impact of the fluid, it is easy...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the problems that the PP filter element in the prior art has low structural strength, is easily deformed under the continuous impact of the fluid, has a short service life, and affects the filtration quality, the PP filter element provided by the present invention adds a layer to the inner wall of the PP filter element body The grid frame is used to support the PP filter body, which increases the structural strength and surface pressure resistance of the PP filter element. Under the continuous impact of the fluid, it is not easy to deform, prolongs the service life, and increases the filtering effect of the fluid.
