Description

A kind of filtering mesh bag

Technical field

This utility model belongs to composite filter material technical field, refers in particular to a kind of filtering mesh bag.

Background technology

At present, in the industrial production, some production there will be a large amount of dust, needs to filter, existing filtration Bag is general by meeting knoisphere, base cloth layer and supporting layer up of three layers, although it can filter certain dust, but it exists filtration Layer line density is excessive, and the excesssive gap between line and line, it is impossible to the problem filtering molecule, and some dust has viscous Property, common filter bag is once attached with dust, if not clearing up, affects filter effect, even results in filter bag and lost efficacy.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in construction and stablizes, the filtering mesh bag of good filtration effect.

The purpose of this utility model is achieved in that

A kind of filtering mesh bag, it is characterised in that: include that mesh bag body, mesh bag body set gradually protected from top to bottom Layer, the first filter course, meet knoisphere, base cloth layer, supporting layer, the second filter course,

Described protective layer is made up of politef, and protective layer is densely covered with through hole, and protective layer is antistick layer；

Described first filter course is made up of the polyphenylether fibre silk screen that average diameter is 3-9 μm；

Described knoisphere of meeting is made up of high-denier-fibre cross lapping；

Described base cloth layer is made up of the braiding of PET long filament；

Described supporting layer is made up of high-denier-fibre cross lapping；

Described second filter course is made up of the polyphenylether fibre silk screen that average diameter is 3-9 μm.

The line density of described base cloth layer is 0.89dtex-2.2dtex.

The weight per unit area of described first filter course and the second filter course is 50-120g/.

Described meeting links reinforcing by acupuncture complex method between knoisphere, base cloth layer and supporting layer.

Described first filter course sticks in meets on knoisphere, and the second filter course sticks on supporting layer, described protective layer adhesion On the first filter course.

Spacing≤2mm between PET long filament and PET long filament in described base cloth layer.

This utility model highlights and useful having the technical effect that compared to existing technology

1, of the present utility model for MULTILAYER COMPOSITE filter cloth, the diameter dust less than less than 2 microns can not only be filtered Grain, and strengthen the bulk strength of filter cloth such that it is able to life-time service in the environment of high intensity, service life is long, crosses and filters Dirt is effective.

2, described protective layer of the present utility model is made up of politef, and politef is non-sticking lining, Ke Yiyou Effect ground solves filter cloth and is attached with the problem of dust, and protective layer is densely covered with through hole, the through hole of non-sticking lining for permeable or Ventilative so that more preferably, and service life is long for its filter effect.

3, described first filter course of the present utility model and the second filter course are fine by the polyphenylene oxide that average diameter is 3-9 μm Dust isolation can be existed by dimension silk screen composition, the first filter course of ultra-fine fibrous web composition and the second filter course effectively Outward, it is to avoid micronic dust gos deep into inside filtering mesh bag, filter effect is improved.

4, meeting knoisphere described in of the present utility model identical with supporting layer material, it has intensity high, heat-resisting and aqueous is good Etc. advantage；Described base cloth layer is made up of the braiding of PET long filament, has good mechanical property, and folding resistance is good, and high temperature resistant and low Temperature；And the line density of base cloth layer is 0.89dtex-2.2dtex, strengthen overall toughness so that structure is the most stable.

Fig. 2 is partial enlarged drawing at the A of Fig. 1.

In figure: 1-the first filter course；2-meets knoisphere；3-base cloth layer；4-supporting layer；5-the second filter course；6-protective layer；7- Through hole.

Detailed description of the invention

With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings, as shown in Fig. 1-2:

A kind of filtering mesh bag, it is characterised in that: include that mesh bag body, mesh bag body set gradually matcoveredn from top to bottom 6, the first filter course 1, meet knoisphere 2, base cloth layer 3, supporting layer the 4, second filter course 5,

Described protective layer 6 is made up of politef, and politef is non-sticking lining, can efficiently solve filter cloth The problem being attached with dust, protective layer 6 surface is densely covered with through hole, and protective layer is antistick layer, and the through hole of non-sticking lining is for permeable Or ventilative so that more preferably, and service life is long for its filter effect；

Described first filter course 1 is made up of the polyphenylether fibre silk screen that average diameter is 3-9 μm, ultra-fine fibrous web group Dust can be completely cut off outside by the first filter course 1 effectively that become, it is to avoid micronic dust gos deep into inside filtering mesh bag, improves and filters effect Really；

Described knoisphere 2 of meeting is made up of high-denier-fibre cross lapping, and it has intensity high, and it is excellent that heat-resisting and aqueous is good etc. Point；

Described base cloth layer 3 by PET long filament braiding make, have good mechanical property, folding resistance is good, and high temperature resistant and Low temperature；And the line density of base cloth layer 3 is 0.89dtex-2.2dtex, strengthen overall toughness so that structure is the most stable；

Described supporting layer 4 is made up of high-denier-fibre cross lapping, and it has intensity high, and it is excellent that heat-resisting and aqueous is good etc. Point；
