Abstract
The utility model relates to a dual-layer filter cloth. A warp is a filament and a woof is a multifilament. The dual-layer filter cloth is formed by a surface layer and a bottom layer. The surface layer and the bottom layer are woven into a whole body through a plurality of interlacing points. The utility model solves the problem that high filtration accuracy and high longitudinal tensile strength of the filter cloth of the prior art cannot be obtained at the same time, and overcomes the defects of the prior art.
Description
Technical field
The utility model relates to a kind of double-decker filter cloth, and particularly relating to a kind of warp is that monofilament, parallel are the double-decker filter cloth of multifilament.
Background technology
Industrial development pole the earth has improved people's material life, but the waste gas contaminated wastewater environment that industrial production produces has become problem anxious to be solved in the world.To protect simultaneously in order developping production better and to improve environment, many effort and practice have been carried out in countries in the world aspect the control of environmental pollution in the last hundred years, and have obtained very big effect.
Whole filtration market is fast-developing, and the application of fibre filtering material in polluting control and environmental improvement more and more widely.The filter cloth material is filtering separation device " heart ", is the pith of decision separating effect, plays crucial effect in industries such as chemical industry, medicine, metallurgy, food.But because the work material nature difference of different industries is big, the environment for use complexity of filter cloth, this has just determined the filter cloth material is selected under the different condition uncertainty and complexity.The development trend of industrial filter material mainly is to improve under the prerequisite of filter efficiency, reduces production costs, improves intensity and increase the service life.
Chinese patent ZL 99258521.X filter cloth discloses a kind of solid-liquid that is used for, the filter cloth that the solid and gas separating and filtering uses, filling yarn all adopts polyester filament, have any surface finish, smooth, hole is trumpet type, have slag dumping easily, long service life, hole be difficult for the advantage of obstruction, health, safety.The industrial filter cloth that 96232134.6 1 kinds of filter presses of Chinese patent ZL are used, adopt five piece two to fly satin organizational structure and Polyamide Yarns is made warp, parallel, this industrial filter cloth had both kept certain intensity, again because filter cloth is thinner than nonwoven filter blanket, increase the filter press filtering material capacity of once installing, improved work efficiency.Also because the filter cloth smooth surface is smooth, the wear resistance height makes the filter press filter cake that very easily comes off, and improves filter cloth service life, is particularly suitable for industries such as coal separation, pottery.The filter cloth that these two patents are introduced is the filter cloth of blank, has only utilized the structure of common fabric, does not also really take into account the angle in service life simultaneously from the raising filtering accuracy and thinks deeply.
It is material with the nylon monofilament that Chinese patent ZL 03280132.7 double ends double weft monofilament filter cloth provides a kind of, by the nylon monofilament of the ganoid circular cross-section of parallel horizontal in twos is that warp and parallel are woven into the highly dense filter cloth of plain weave, has adopted double ends, double weft plain weave structure.Chinese patent ZL01274154.X filter cloth, be that the warp employing is formed by monofilament and a certain proportion of combination of multifilaments, parallel adopts multifilament, weave the existing density preferably of the filter cloth that forms, intensity like this, has gas permeability preferably again, less advantages such as filtration resistance have been taken into account the advantage of multifilament filter cloth and monofilament filter cloth.Chinese patent ZL02204517.1 industrial filter cloth originally relates to a kind of industrial filter cloth that is used for Separation of Solid and Liquid, is interwoven by warp and parallel, it is characterized in that parallel is arranged in parallel by monofilament and multifilament to form.Parallel of the present utility model combines the advantage that monofilament and multifilament have, and makes filter cloth have suitable tight ness rating and smoothness, can satisfy different filtration requirements, and resistance is little, is difficult for stopping up, and the rate of filtration is very fast and effective, has improved work efficiency.More than the technology introduced of three patents be the filter cloth that is in the junior stage, the way of the graticule various combination by fabric satisfies the requirement that part is filtered, but because single layer structures just also all, filter effect is not ideal.
Chinese patent application 200810106708.X monofilament double-layer filtering cloth discloses monofilament double-layer filtering cloth and has been weaved by double-layered structure by the monofilament of terylene, polypropylene fibre or other raw material, this tissue is made up of table organization and lining tissue, table organization is 4/1 brokentwlllweave, in be organized as 2/2 twill left to right, the table back warp is arranged than being 4: 1, and the arrangement of table back weft is than being 2: 1; The common used monofilament of table organization is thinner, and tissue common used monofilament in lining is thicker.In use, the thin monofilament interception in top layer material, the thick monofilament of bottom increases the brute force of cloth, thereby realizes Separation of Solid and Liquid fast.This patented technology is because adopted monofilament to be made into double-decker, and the void ratio between monofilament is bigger, can't meet the needs of the occasion that high accuracy is filtered.
Summary of the invention
The purpose of this utility model provides the utility model and relates to a kind of double-decker filter cloth, particularly relating to a kind of warp is that monofilament, parallel are the double-decker filter cloth of multifilament, the utility model has solved the filter cloth filtering accuracy of prior art and the problem that longitudinal tensile strength can not get both, and remedies the deficiencies in the prior art.
A kind of double-decker filter cloth of the present utility model, warp is a monofilament, and parallel is a multifilament, and described double-decker filter cloth is made up of surface layer and the two-layer cloth cover of bottom, and the two-layer cloth cover of surface layer and bottom is woven into one by some interlacing points.Warp adopts monofilament, has guaranteed the longitudinal tensile strength of filter cloth, and parallel adopts multifilament, has improved the filtering accuracy and the filter efficiency of filter cloth; Surface layer can be the different fiber of filament number as the multifilament of parallel and bottom as the multifilament of parallel, realizes double-filtration, further improves filtering accuracy.
As optimized technical scheme:
Wherein, aforesaid a kind of double-decker filter cloth, the cloth cover weave of described surface layer and bottom is similar and different.
Aforesaid a kind of double-decker filter cloth, described surface layer are 1/3 tissue, and bottom is 2/2 tissue.
