Multilayered filter screen

Abstract

The invention belongs to the technical field of application of filter screens and particularly discloses a multilayered filter screen. The multilayered filter screen comprises a first rib framework and a second rib framework connected with the first rib framework, wherein the first rib framework and the second rib framework are connected through a positioning screw rod; the structures and sizes of the first rib framework and the second rib framework are the same; and a first filter screen and a second filter screen are arranged on the first rib framework and the second rib framework respectively. The multilayered filter screen disclosed by the invention has the beneficial effects that the design structure is reasonable and the filter screens are arranged on the rib frameworks; the whole composition structure is stable and the toughness is high; no breaking phenomenon exists and the service life is long, so that the multilayered filter screen does not need to be usually overhauled and the efficiency of equipment matched with the multilayered filter screen is high; and meanwhile, a filter screen surface can be replaced according to different filtering demands, so that the production cost of enterprises is reduced and the applicable range is wide.

Description

technical field [0001] The invention belongs to the technical field of filter net applications, and in particular relates to a multi-layer filter net, which is suitable for various environments and has strong toughness, wear resistance, corrosion resistance, high temperature resistance and long service life. Background technique [0002] Filter screens, generally made of metal or synthetic fibers, are used for the separation of various fluid substances, generally resistant to corrosion, oxidation, etc. Increase material flow resistance to filter out mechanical impurities and improve the effect of mixing or plasticizing. It has properties such as acid resistance, alkali resistance, temperature resistance, and wear resistance. It is mainly used in mining, petroleum, chemical, food, medicine, machinery manufacturing, etc. At the same time, the filter screen is divided into textile fiber filter screen and metal filter screen. [0003] It is usually suitable for screening and fi...
