Abstract

The utility model relates to a novel composite filter cloth, which comprises a base cloth and a filter cloth, wherein the composite filter cloth comprises at least two layers of filter cloth, the first layer of filter cloth is woven by a plurality of warps and wefts, and the warps and the wefts are mutually vertical; the second layer of filter cloth is woven by a plurality of warps and wefts, and the included angle between the warps and the wefts is larger than zero and smaller than 90 degrees. The included angle between the warp and the weft of the second layer of filter cloth is 45 degrees; the warp of the filter cloth is glass fiber, polypropylene filament or basalt fiber, and the weft of the filter cloth is a polypropylene tearing film. Compared with the prior art, the utility model discloses compound filter cloth warp and weft connection are firm, can not produce and slide under the great wind pressure of dust remover, can effectively keep better aperture and filter fineness, filter stably, dust removal effect is good, and life is longer.

Description

Novel composite filter cloth

Technical Field

The utility model belongs to the technical field of the filter cloth technique and specifically relates to a novel composite filter cloth for industrial dust collecting equipment.

Background

Currently, the filter cloth used in the existing industrial dust collector generally has a filter cloth made of filament and spun yarn, or a filter cloth woven by monofilament and filament. The former has small hardness and low strength, is easy to damage in the blowing dust removal process of dust removal equipment and has short service life. The monofilament and the filament of the filter cloth of the latter are easy to slide under the larger wind pressure of the dust remover, so that the local aperture of the filter cloth is increased, and the filtering and dust removing effect is influenced.

SUMMERY OF THE UTILITY MODEL

Not enough to above current filter cloth, the utility model aims at providing a novel composite filter cloth that filter fineness is stable, long service life, and the filter dust removal effect is better.

The purpose of the utility model is realized by adopting the following technical scheme:

a novel composite filter cloth comprises a base cloth and a filter cloth, wherein the composite filter cloth comprises at least two layers of filter cloth, the first layer of filter cloth is formed by weaving a plurality of warps and wefts, and the warps and the wefts are vertical to each other; the second layer of filter cloth is woven by a plurality of warps and wefts, and the included angle between the warps and the wefts is larger than zero and smaller than 90 degrees.

As the preferred technical scheme of the utility model, the contained angle between second layer filter cloth warp and the weft is 45 degrees.

As the preferred technical scheme of the utility model, the warp of filter cloth is glass fiber, polypropylene fibre long filament or basalt fiber, the weft of filter cloth is the polypropylene fibre tear film.

As the preferred technical scheme of the utility model, base cloth includes polypropylene, polyethylene or dacron non-woven fabrics.

As the preferred technical proposal of the utility model, the filter cloth and the base cloth are connected and compounded into a whole through bonding or needling.

As the preferred technical scheme of the utility model, the whole thickness of compound filter cloth is 0.20 millimeter to 0.55 millimeter.

The utility model has the advantages that: compared with the prior art, the utility model discloses compound filter cloth warp and weft connection are firm, can not produce and slide under the great wind pressure of dust remover, can effectively keep better aperture and filter fineness, filter stably, dust removal effect is good, and life is longer.

Drawings

The invention will be further described with reference to the following detailed description of the embodiments with reference to the accompanying drawings:

fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic structural diagram of the first layer of filter cloth of the present invention.

Fig. 3 is a schematic structural diagram of the second layer of filter cloth of the present invention.

In the figure: 1. base cloth, 2, filter cloth, 21, first layer filter cloth, 22, second layer filter cloth.

Detailed Description

As shown in fig. 1 to 3, a novel composite filter cloth comprises a base cloth 1 and a filter cloth 2, wherein the filter cloth 2 has two layers, the first layer of filter cloth 21 is woven by a plurality of warps and wefts, and the warps and the wefts are vertical to each other; the second layer of filter cloth 22 is woven by a plurality of warps and wefts, and the included angle between the warps and the wefts is larger than zero and smaller than 90 degrees.

In this embodiment, the included angle between the warp and the weft of the second layer of filter cloth 22 is 45 degrees. The warp of the filter cloth 2 is glass fiber, polypropylene filament or basalt fiber, and the weft of the filter cloth 2 is a polypropylene tearing film. The base cloth 1 comprises polypropylene, polyethylene or polyester non-woven fabric; the filter cloth 2 and the base cloth 1 are combined into a whole through bonding or needling. The overall thickness of the composite filter cloth of the embodiment is 0.20 mm to 0.55 mm.

The utility model discloses weft adopts comparatively crude polypropylene fibre in surface to tear the membrane for frictional resistance between warp and the weft increases, and base cloth 1 adopts the non-woven fabrics and with filter cloth 2 complex as an organic whole, has further strengthened the effort between warp and the weft, even under the great wind pressure of dust remover, warp and weft can not slide yet, connect firmly, thereby make the filter cloth can effectively remain stable filtration aperture, improve dust removal effect, the life of filter cloth also further prolongs.

The above embodiments are only for illustrating the conception and technical features of the present invention, and the purpose thereof is to make the technical personnel skilled in the art understand the technical solution and implementation mode of the present invention, and thus the protection scope of the present invention can not be limited thereby. All equivalent substitutions or equivalent changes made according to the technical scheme of the invention are intended to be covered by the protection scope of the claims of the invention.
