Problems solved by technology

[0004] The multi-layer filter with traditional structure, on the one hand, has a complex structure and is inconvenient to install, produce, assemble, disassemble and use, and at the same time, it is prone to breakage and aging after long-term use, resulting in a short service life and requiring regular maintenance, which affects the equipment used in conjunction with it. Work efficiency can no longer meet the assembly and use requirements of existing equipment. At the same time, the entire filter structure needs to be replaced as a whole for different filtration requirements, which increases the economic cost of the enterprise. This is an urgent problem to be solved at present.

Embodiment Construction

[0015] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 , figure 2 with image 3 The multi-layer filter shown includes a first rib frame 1 and a second rib frame 2 connected to the first rib frame 1, wherein the positioning screw is used between the first rib frame 1 and the second rib frame 2 3 connected, and the first rib frame 1 and the second rib frame 2 have the same structure and size, and the first filter screen 4 and the second filter screen 5 are respectively arranged on the first rib frame 1 and the second rib frame 2.

[0017] Further preferably, both the first filter screen 4 and the second filter screen 5 are filter screens woven with stainless steel wires, the weaving structure is stable and has strong corrosion resistance, wear resistance, high temperature resistance, and long service life; and The mesh diameter of the first filter screen 4 is smaller than ...

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...
