Description

A kind of composite filter cloth with viscose layer

technical field

The utility model relates to the technical field of filter cloth, in particular to a composite filter cloth provided with a viscose layer for industrial dust removal equipment.

Background technique

At present, the surface of the filter cloth used in the filter bag of the existing industrial dust collector is generally a flat structure. During the working process of the dust collector, the dust gradually accumulates on the surface of the filter cloth of the filter bag. When the dust accumulates on the surface of the filter cloth to a certain extent, the filter bag The difference between internal and external pressure is reversed, or the filter bag is vibrated by the blowing device of the dust collector, so that the dust on the surface of the filter bag shakes and falls. The filter cloth of the existing filter bag will be blocked after long-term use, and the amount of dust shaken off when the filter bag is vibrated is reduced, which not only affects the filtering and dust removal effect of the dust collector, but also increases the breakage rate of the filter bag and reduces the use of the filter bag life.

At present, the country's requirements for environmental protection are gradually increasing. The diameter of the dust particles filtered by the ordinary filter bag of the existing bag filter is relatively large, and there are still a large number of dust with small particle diameters that will be discharged into the atmosphere. For some environmental protection standards High industries can no longer meet the requirements.

Utility model content

In view of the deficiencies of the existing dust collector filter bags above, the purpose of this utility model is to provide a composite filter cloth with a viscose layer which has a better dust removal effect.

The purpose of this utility model is achieved by adopting the following technical solutions:

A composite filter cloth provided with a viscose layer, comprising a base cloth and a filter cloth, the base cloth is a grid-shaped plain weave cloth, the plain weave cloth is woven from several warp threads and weft threads, and the warp threads and weft threads are perpendicular to each other; The filter cloth is a non-woven fabric made of thermoplastic fibers, and a viscose layer is arranged between the base cloth and the filter cloth and connected to form an integral structure.

As a preferred technical solution of the present utility model, the base cloth is composed of two layers of woven cloth, the first layer of base cloth is the plain weave cloth; the second layer of woven cloth is a twill weave cloth, and the twill weave cloth is composed of several warps and wefts Woven, the angle between the warp and weft is 45 degrees.

As a preferred technical solution of the present invention, a viscose layer is also provided between the first layer of plain weave cloth and the second layer of twill weave cloth.

As a preferred technical solution of the present invention, the adhesive layer includes resin glue.

As a preferred technical solution of the utility model, the non-woven fabric is formed by laminating or blending polyester fibers or polyphenylene sulfide fibers.

The beneficial effects of the utility model are: compared with the prior art, the utility model further enhances the ability of the filter cloth to absorb and filter dust with smaller particle diameters by setting a resin glue layer between the base cloth and the filter cloth. The utility model has better dust collection and dust removal effects, and the filter bag is not easy to be blocked, is suitable for various industrial dust collectors, and can meet higher environmental protection emission standards.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a structural schematic diagram of the grid plain weave cloth of the present invention.

Fig. 3 is a schematic diagram of the structure of the twill weave fabric of the present invention.

In the figure: 1. filter cloth, 2. base cloth, 3. viscose layer, 21. mesh plain weave cloth, 22. twill weave cloth.

Detailed ways

As shown in Fig. 1 to Fig. 3, a kind of composite filter cloth that is provided with viscose layer, comprises base cloth 2 and filter cloth 1, and described base cloth 2 is grid shape plain weave cloth 21, and plain weave cloth 21 is made of several The warp and weft are woven, and the warp and weft are perpendicular to each other; the filter cloth 1 is a non-woven fabric made of thermoplastic fibers, and a viscose layer 3 is arranged between the base cloth 2 and the filter cloth 1 and connected to form an overall structure.

In this embodiment, the base cloth 2 is made of two layers of woven cloth, the first layer of base cloth is the plain weave 21; the second layer of woven cloth is a twill weave 22, and the twill weave 22 is composed of several warps and wefts. Woven, the angle between the warp and weft is 45 degrees. A viscose layer is also provided between the first layer of plain weave cloth 21 and the second layer of twill weave cloth 22 . The viscose layer of the utility model includes resin glue; the non-woven fabric includes polyester fiber or polyphenylene sulfide fiber through lamination or blending. The structure of this embodiment is beneficial to the adsorption of dust particles by the composite filter cloth as a whole.

The above-mentioned embodiments are limited to explaining the concept and technical features of the utility model, and its purpose is to let those skilled in the art understand the technical solution and implementation of the utility model, and cannot limit the protection scope of the utility model accordingly. All equivalent replacements or equivalent changes made according to the technical solution of the utility model shall be covered within the protection scope of the claims of the utility model.
