Abstract

The utility model discloses a monofilament and multifilament double-layer filtration cloth. The filtration cloth is woven by a Dornier loom; warps are polypropylene or polyester monofilament warps; wefts are polypropylene or polyester multifilament wefts; the monofilament warps penetrate through two multifilament wefts and then synchronously penetrate through another two multifilament wefts to continuously extend; every two adjacent monofilament warps are staggered from each other; and a surface formed by the monofilament warps is sized by matting. The monofilament and multifilament double-layer filtration cloth has a double-warp and double-weft structure; one surface of the monofilament and multifilament double-layer filtration cloth is a supporting layer which is formed by the monofilament warps and is sized by matting, and the other surface of the monofilament and multifilament double-layer filtration cloth is a multifilament filtration layer which is formed by the multifilament wefts, can permeate air and water and is not transparent; the filtration cloth has a smooth surface and is high in abrasion resistance; a filtration cake is easy to fall down and clean; the filtration efficiency is improved; and the monofilament and multifilament double-layer filtration cloth has the characteristics of acid resistance, alkaline resistance and high-temperature resistance, is mainly applied to filtration equipment such as pressure filters, band type vacuum filters, centrifugal machines and vertical plate machines in the industries of mineral separation, aluminum oxide plants, sugar plants, power plants, food and sewage treatment and the like.

Description

A kind of single multifilament double-layer filtering cloth
Technical field
The utility model relates to industrial filter cloth technical field, relates in particular to a kind of single multifilament double-layer filtering cloth.
Background technology
Filtration is one of liquid-solid separation unit operation that often adopts in the Chemical Manufacture, it is to add outside under the effect of pressure difference, makes liquid-solid mixture flow through porous media (filter cloth), and solid particle is filtered cloth and holds back, liquid is the hole by filter cloth then, thereby realizes the purpose that liquid-solid two-phase separates.Filtration plays an important role in solving resource, the energy and environmental protection three big problems.
Filter cloth is a kind of filter medium, directly influences filter effect, and existing industrial filter cloth adopts conventional multifilament material substantially, and the individual layer braiding forms, and fabric face is coarse, stops up easily in filter process, and is not easy to clean, and filter efficiency is poor.
Summary of the invention
At above-mentioned defective, the utility model provides a kind of single multifilament double-layer filtering cloth, the filter cloth smooth surface, and filter cake comes off easily, easy cleaning, thereby improves filter efficiency.
To achieve these goals, the technical solution of the utility model is: a kind of single multifilament double-layer filtering cloth, the warp of this filter cloth is polypropylene or monofilament polyester warp, parallel is polypropylene or polyester multifilament parallel, after described monofilament warp passes two multifilament parallels, pass other two multifilament parallels more simultaneously and extend continuously, every two adjacent monofilament warps stagger.
Further, described filter cloth is weaved by many Neils loom and is formed.
Further, the formed surface of described monofilament warp is through the light typing.
Single multifilament double-layer filtering cloth of the present utility model is made by force by many Neils of import loom and to be formed, and is double ends double weft structure.One side forms supporting layer by the monofilament warp, and pass through light and finalize the design, one side forms the multifilament filter course by the multifilament parallel, and air-and water-permeable is not expected thoroughly, this filter cloth smooth surface, wearability is good, filter cake easily comes off, and easy cleaning improves filter efficiency, and have acidproof, alkaline-resisting, resistant to elevated temperatures characteristic, be mainly used in filter plants such as the filter press, belt vacuum filter, centrifuge of industries such as ore dressing, alumina producer, sugar refinery, power plant, food and sewage disposal, upright dish machine.
Description of drawings
Fig. 1 is single multifilament double-layer filtering cloth graticule braiding structure schematic diagram of the present utility model.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, single multifilament double-layer filtering cloth of the present utility model, formed by longitude and latitude and parallel braiding, 1,2 is two adjacent warps among the figure, and 3 is parallel, and the warp of this filter cloth is polypropylene or monofilament polyester warp, parallel is polypropylene or polyester multifilament parallel, after described monofilament warp passes two multifilament parallels, pass other two multifilament parallels more simultaneously and extend continuously, every two adjacent monofilament warps stagger.
Described filter cloth is weaved by many Neils loom and is formed.
The formed surface of described monofilament warp is through the light typing.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model all falls within the protection domain of the present utility model.

Claims (1)

1. single multifilament double-layer filtering cloth, it is characterized in that: the warp of this filter cloth is polypropylene or monofilament polyester warp, parallel is polypropylene or polyester multifilament parallel, after described monofilament warp passes two multifilament parallels, pass other two multifilament parallels more simultaneously and extend continuously, every two adjacent monofilament warps stagger.
