Abstract
The invention discloses monofilament double-layer filter cloth, which is woven by terylene, polypropylene fiber, or other material monofilament according to a double-layer structure. The structure consists of a surface structure and a lining structure; the surface structure is 4/1 cross twill, the lining structure is 2/2 left-to-right twill, the array ratio of the surface warp to the lining warp is 4 to 1, the array ratio of the lining woof to the lining woof is 2 to 1. The monofilament usually adopted by the surface structure is thinner; the monofilament usually adopted by the lining structure is thicker. During the usage, the thin monofilament of the surface layer intercepts the materials, and the thick monofilament of the bottom layer enhances the strength of the cloth, so that the solid can be quickly separated from the liquid.
Description
Technical field
The present invention relates to realize the monofilament double-layer filtering cloth of Separation of Solid and Liquid, relating in particular to can the bigger monofilament double-layer filtering cloth of filter material viscosity.
Background technology
At present, most of Woven filter cloth is made up of multifilament, short fiber on the domestic market, and tissue mostly is plain weave, twill, satin weave or their alternative construction, all is monolayer organization.In use, suspension contacts with filter cloth, solid particle less than the filter cloth aperture under the effect of pressure passes filter cloth, be trapped within surface formation one deck filter cake of filter cloth more than or equal to the particle in filter cloth aperture, then the filter cake by progressive additive continues trapped particles, thereby realizes Separation of Solid and Liquid.But in use there is following problem: 1, when the material viscosity surpasses certain value, be easy to stop up by the filter cloth that multifilament and short fiber are formed; 2, bacterium is easy to grow; 3, lack service life, power of regeneration is poor; 4, filter cake and filter cloth stripping performance are poor, and general woven filter cloth can not filter the bigger material of viscosity, cause difficulty for the bigger material of filtration viscosity, and efficient is low, the cost height.
Summary of the invention
For solving above-mentioned middle problem and the defective that exists, the invention provides monofilament double-layer filtering cloth.
The present invention is achieved by the following technical solutions:
Monofilament double-layer filtering cloth involved in the present invention, comprise: described monofilament double-layer filtering cloth adopts the macromolecule raw material monofilament different with specification to arrange according to double-layered structure, described double-layered structure is table organization and lining tissue, wherein table organization selects 4/1 brokentwlllweave for use, graticule is selected thinner monofilament for use, and specification is 0.25 millimeter of 0.18 millimeter～Ф of Ф; Tissue is selected 2/2 twill left to right for use in described, and graticule is selected thicker monofilament for use, and specification is 0.50 millimeter of 0.25 millimeter～Ф of Ф.
Described macromolecule raw material is polypropylene fibre and terylene.The table back warp is arranged than being 4: 1 in the monofilament double-layer filtering cloth double-layered structure structure, and the arrangement of table back weft is than being 2: 1.Described thin monofilament concentrates on the surface of filter cloth, and thick monofilament concentrates on the bottom of filter cloth, and forms up-small and down-big horn-like hole.
The beneficial effect of technical scheme provided by the invention is:
Can the bigger material of filter material viscosity, long service life is easy to clean, and regenerability is good.

Fig. 1 is a monofilament double-layer filtering cloth table organization structural representation;
Fig. 2 is an institutional framework schematic diagram in the monofilament double-layer filtering cloth;
Fig. 3 is the organization chart of monofilament double-layer filtering cloth;
Fig. 4 is that the warp-wise of monofilament double-layer filtering cloth cuts and schemes.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing:
Present embodiment provides monofilament double-layer filtering cloth.
Be respectively the table organization and the lining tissue of monofilament double-layer filtering cloth referring to Fig. 1, Fig. 2, wherein table organization selects 4/1 brokentwlllweave for use, and graticule is selected thinner branch silk for use, and specification is 0.25 millimeter of 0.18 millimeter～Ф of Ф; In be organized as 2/2 twill left to right, graticule is selected thicker monofilament for use, specification is 0.50 millimeter of 0.25 millimeter～Ф of Ф.
Cut for the tissue and the warp-wise of monofilament double-layer filtering cloth referring to Fig. 3, Fig. 4, what Arabic numerals 1～16 were represented is to show through the table latitude, and what Latin I～IV represented is the back warp back weft.Symbol wherein
The expression table through with the table latitude place that interweaves, symbol
Expression back warp and the back weft place that interweaves, symbol
The expression table through with the back weft place that interweaves, symbol
Expression back warp and the table latitude place that interweaves, wherein, the arrangement of described table back warp ratio is 4: 1, the arrangement ratio of showing back weft is 2: 1; The access node method is a binding pick access node method.Described tissue makes thin monofilament concentrate on the filter cloth surface, and thick monofilament concentrates on the bottom of filter cloth, and thick monofilament increases the filter cloth brute force in this structure, thereby satisfies the strainability and the requirement of strength of filter cloth.Described thin monofilament top is the front working face, thick line and be reverse side, in use, material is added on the working face, by applying malleation or negative pressure, pass the filter cloth infiltration in the past less than the particle in filter cloth aperture in the material, greater than the particle in filter cloth aperture by the fine rule interception at the table of filter cloth and, thereby realize the separation of solid-liquid.
Present embodiment also is not easy to stop up when the material viscosity surpasses certain value, prevent growing of bacterium, and service life, longer regenerability is good, can filter the bigger material of viscosity, has not only improved efficient, has also reduced production cost.
The above; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
