Wherein, described filter cloth texture is multiply cloth structure, comprises top layer 3/1 twill and nexine 3/1 through double combination, or top layer 2/2 twill and nexine 1/3 are through double combination, or line and nexine 3/1 and 2/2 are forged through double combination in top layer 4/1.
Wherein, described filter cloth texture is multiply cloth structure, at least comprises the hydrophobic layer of dam layer and bottom on surface, described in the layer that dams be twill, hydrophobic layer is asymmetrical warp backed weave, and the layer that dams interweaves with hydrophobic layer and is connected.
Compared with prior art, the utility model has following beneficial effect:
The polypropylene fibre filter cloth of use super fine denier number porous multifilament adds the perforate number in filter cloth unit are to greatest extent, namely effective filter area is added, this measure not only adds filter cloth and retains precision to particle, opened abundant filtration duct, ensure that has sufficiently high discharge opeing speed while high rejection simultaneously; The grain design of filter cloth not only has firmly dimensional stability, avoids in use repeatedly stressed and filter cloth that is that cause relaxes, and decreases material particles remaining on filter cloth, and the fissility of filter cake is fine.
Accompanying drawing explanation
Fig. 1 is that the present invention adopts top layer 2/2 twill, lower floor through the filter cloth fabric face Electronic Speculum enlarged drawing of double texture;
Fig. 2 is filter cloth fabric backing Electronic Speculum enlarged drawing in Fig. 1;
Fig. 3 is filter cloth fabric side Electronic Speculum enlarged drawing in Fig. 1.
Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1 ~ Fig. 3, for one embodiment of the invention be applied to employing top layer 2/2 twill that non-ferrous metal high-purity extracts, lower floor through the filter cloth front of double texture, the Electronic Speculum enlarged drawing of reverse side and side.
Be applied to the filter cloth that non-ferrous metal high-purity is extracted, the multifilament of filter cloth adopts super fine denier number porous polypropylene fibre multifilament, and this filter cloth is weaved by warp and parallel and made, and the texture structure of filter cloth is any one in plain weave, twill, satin weave or all multiply cloth structures.
Compare existing filter cloth and adopt normal polypropylene material, fiber Denier is larger, and hole count is less, the polypropylene fibre filter cloth of super fine denier number porous polypropylene fibre multifilament of the present invention adds the perforate number in filter cloth unit are to greatest extent, namely effective filter area is added, which not only adds the dam precision of filter cloth to particle, opened abundant filtration duct simultaneously, while ensure that high interception capacity, had abundant discharge opeing speed.
Preferably, polypropylene fibre multifilament adopts FDY super fine denier number porous polypropylene fibre long fine, and single fiber is no more than 3 D.
As the preferred preferred embodiment of another kind, single Shu Fusi hole count is 240-1200 hole.
Preferably, the line density of polypropylene fibre multifilament is 300-4000 D.
Preferably, the twist of polypropylene fibre list Shu Fusi is not less than 200 twists/m.
Preferably, on polypropylene fibre multifilament, machine warp-wise density is 200-1000 root/10cm.
In this programme, grain design is applicable to plain weave, twill, satin weave and all multiply cloth structures.Plain weave, twill, satin weave are the basic textures of three foundation weave, and belong to woven structure, plain weave is the finest and close, but its hole easily blocks, and filter cake is also slightly difficult to be peeled off; The intensity of twill-weave is the highest, and micropore not easily blocks, and flow is large; Satin weave is concentrated because of its vertical silk and is prepared, and filter cake fissility is good, but particle capturing ability is poor.Multiply cloth structure is the combination of three foundation weave, belongs to two-layer and two-layer above fabric.
As preferred embodiment, filter cloth texture is multiply cloth structure, can be top layer 3/1 twill and nexine 3/1 through double combination, or top layer 2/2 twill and nexine 1/3 are through double combination, or line and nexine 3/1 and 2/2 are forged through double Assembled lamp in top layer 4/1, are not limited thereto.Different combination textures and different graticule proportionings can reach different and retain precision, can be applied to different industries, as Coal Chemical Industry, power plant desulfurization, biological extraction etc., can select flexibly according to actual conditions.
As preferably embodiment, filter cloth texture is multiply cloth structure, and at least comprise the hydrophobic layer of dam layer and the bottom on surface, the layer that dams is twill, and hydrophobic layer is asymmetrical warp backed weave, and the layer that dams interweaves with hydrophobic layer and is connected.In this embodiment, special lines design and yarn proportioning (being 1:1 in the utility model) by filter cloth retain layer and lyophoby supporting layer has accomplished the differentiation of function, increase hydrophobicity to greatest extent under guarantee retains the prerequisite of precision.Lyophoby supporting layer adopts the high-strength porous polypropylene fibre of FDY long fine, and make filter cloth have good tensile strength and dimensional stability, the hydrophobic channel of taper and the sideshake of amplification can accelerate hydrophobic efficiency.Lower floor's chevron structure well can ensure filter cloth stability in the running, specifically can with reference to figure 1 ~ Fig. 3.
In multiply cloth structure of the present utility model, when top layer to nexine wire diameter from fine to coarse; Top layer to the density of nexine by close to rare; The aperture of nexine texture is larger than top layer, can form the sideshake of taper hydrophobic channel and amplification.Lower floor's chevron structure be twill and Drafting Method be combined to form herringbone, such as four heald frames, the order of gaiting of wearing one fixed width is 1234, then wears 4321 of one fixed width conversely.
Filter cloth of the present utility model, filter in the production of horizontal belt vacuum machine for certain enterprise's cobalt carbonate material domestic, material smallest particles 0.5 μm, rejection is 99%, and the moisture content of filter cake is lower than 18%, and result of use is good.
Filter cloth of the present utility model has very high particle entrapment precision, effectively can improve quality and the recovery rate of product in the application of non-ferrous metal industry, and good permeability rate and the easy fissility of splendid filter cake, can ensure high efficiency and the stability of device fabrication.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
