Abstract
The open a kind of three layers of compound filter cloth of the utility model, it comprises the first filter layer of cloth, filter membranous layer and the second filter layer of cloth that sequentially arrange from top to bottom.Described filter membranous layer is PTFE filter membrane or PU filter membrane.Described first filter layer of cloth and the second filter layer of cloth all adopt chemical fibre to be formed by weaving through loom longitude and latitude, and thread count is no less than 5 pieces/centimetre.Described warp thread and weft yarn are polypropylene fibre, terylene, acrylic, PTFE, PPS, PVDF, P84 or aramid fiber material.The present invention utilizes the structure being provided with filter layer of cloth on the two sides of filter membranous layer, solves the problem worn no resistance when filter membrane contacts with particle.Meanwhile, relative to the filter cloth of prior art, achieve under the condition not changing filter cloth material density, just can purify to the filtration of the particle of 0.1 to 10 micron of size.
Description
Technical field
The utility model relates to makes material carry out the technical field of filter cloth being separated and filtering, and particularly relates to a kind of three layers of compound filter cloth.
Background technology
Filter cloth is for allowing suspension contact with filter cloth, be less than the solid particulate matter in filter cloth aperture under the effect of the pressure through filter cloth, and the particle being more than or equal to filter cloth aperture is trapped within a kind of filter on the surface of filter cloth.
At present, if need to adapt to the filtration to different size particles material, the convention of people considers to improve count to change the size in filter cloth hole.But the aperture of filter cloth of the prior art is difficult to the size accomplishing to be less than 10 microns.Therefore filter cloth of the prior art is when collection material, and filter cloth is good not to the filter efficiency of less than 10 microns materials, cause a lot of more valuable granule materials being less than 10 microns in liquefied gas or liquid along with gas or fluid loss.Particularly other material filtering filter cloth of a kind of minimum microsize grade is badly in need of in the ultrafinepowders such as photovoltaic industry and dyestuff industry field of reclaiming.
Utility model content
In order to solve the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of three layers of compound filter cloth can accomplishing the fine particulate matter of filtration 10 micron level.
To achieve these goals, the technical solution adopted in the utility model is: a kind of three layers of compound filter cloth comprise the first filter layer of cloth, filter membranous layer and the second filter layer of cloth that sequentially arrange from top to bottom; And the worry hole of the worry hole of the first filter layer of cloth and the second filter layer of cloth shifts to install.
Described filter membranous layer is PTFE filter membrane or PU filter membrane.
Described first filter layer of cloth and the second filter layer of cloth comprise warp thread and weft yarn, and described first filter layer of cloth and the second filter layer of cloth all adopt chemical fibre to be formed by weaving through loom longitude and latitude, and thread count is no less than 5 pieces/centimetre.
Described warp thread is polypropylene fibre, terylene, acrylic, PTFE, PPS, PVDF, P84 or aramid fiber.
Described weft yarn is polypropylene fibre, terylene, acrylic, PTFE, PPS, PVDF, P84 or aramid fiber.
Described filling yarn is monofilament yarn.
Described filling yarn is folded yarn.
Described filter membranous layer is water-wet behavior.
Described filter membranous layer is hydrophobic property.
The beneficial effects of the utility model are: the present invention utilizes the structure being provided with filter layer of cloth on the two sides of filter membranous layer, solve the problem worn no resistance when filter membrane directly contacts with particle.Meanwhile, relative to the filter cloth of prior art, achieve under the condition not changing filter cloth material density, just can purify to the filtration of the particle of 0.1 to 10 micron of size.The present invention utilizes the structure being provided with filter layer of cloth on the two sides of filter membranous layer, achieves under the condition not changing filter cloth pore size, just can purify to the filtration of the particle of 0.1 to 10 micron of size.Meanwhile, relative to the filter cloth of prior art, the anti-wear performance that filter cloth strengthens whole compound filter cloth is all set on filter membrane two sides.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of three layers of compound filter cloth of the utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with detailed description of the invention also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figure 1, a kind of three layers of compound filter cloth comprise the first filter layer of cloth 1, filter membranous layer 2 and the second filter layer of cloth 3 that sequentially arrange from top to bottom; And the worry hole of the worry hole of the first filter layer of cloth 1 and the second filter layer of cloth 3 shifts to install.Described filter membranous layer 2 is PTFE filter membrane or PU filter membrane.Described first filter layer of cloth 1 and the second filter layer of cloth 3 comprise warp thread and weft yarn, and described first filter layer of cloth 1 and the second filter layer of cloth 3 all adopt chemical fibre to be formed by weaving through loom longitude and latitude, and thread count is no less than 5 pieces/centimetre.Described warp thread is any combination of a kind of material in polypropylene fibre, terylene, acrylic, PTFE, PPS, PVDF, P84 or aramid fiber or two kinds and above material.Described weft yarn is any combination of a kind of material in polypropylene fibre, terylene, acrylic, PTFE, PPS, PVDF, P84 or aramid fiber or two kinds and above material.Described filling yarn can be monofilament yarn, also can be folded yarn.Described filter membranous layer 2 can be water-wet behavior, also can be hydrophobic property.
Above-mentioned three layers of compound filter cloth can obtain by the following method:
Filter cloth adopts chemical fibre fiber characteristics to adopt loom weaving, warp thread is the organic or inorganic fibers such as polypropylene fibre, terylene, acrylic, PTFE, PPS, PVDF, PFA, P84, aramid fiber with weft yarn, yarn feature monofilament or folded yarn, braiding can be the same monofilament of monofilament, the same folded yarn of monofilament, the same folded yarn of folded yarn.Thread count is no less than 5/cm and is made into filter cloth, carry out shaping and surperficial calendering process according to the surface smoothness in face again, again can according to final application, cloth is carried out chemical finishing again, after cloth is placed on compounding machine the polishing of cloth one side carried out compound with film, the tension force pulling force of control temperature and blowing collecting machine in recombination process, after first two layers of compound is good, again by good for compound first put time compounding machine in, temperature is controlled between 150-350 degree with the PTFE film of this two aspect or PU by finish side to be composite, the speed of service controls between 3-20 rice, suitable tension force and pulling force.Warp thread and weft yarn can be single material or more than two kinds and two kinds material mixed textiles.Filter membrane material is PTEE or PU, and membrane material can select water wetted material, also can select hydrophobic material.
