Abstract
The utility model relates to the special filter cloth for a vertical press type filter, which belongs to the field of industrial filter cloth. The special filter cloth is interleaved with multifilaments and a tearing film. The multifilament completely floating on the surface of the cloth cover plays a good interception effect. The interior of the whole cloth is made of the tearing film and the tearing film is good in permeability performance. Therefore, when the material enters the interior of the cloth, the effects of both good filtering performance and prolonged service life of the filter cloth are realized. In addition, the tearing film is adopted as the weft wires of the filter cloth, so that the filter cloth is qualified in stiffening degree and abrasion resistant degree and various in cloth cover style. Therefore, the filter cloth can meet the requirements of a vertical type filter press. Meanwhile, long wires floating on the cloth surface and smooth cloth cover are ensured through the 3/11/3 composite tissue weaving method. Since the filament is excellent in permeability performance, materials can successfully pass through the filament without residues in the cloth. Therefore, the service life of the cloth is not influenced.
Description
Technical field
The utility model relates to the special-purpose filter cloth of upright pressure type filter, belongs to industrial filter cloth field.
Background technology
Vertical press filtration: claim filter cloth full walking automatic pressure filter again, be widely used in the filtration of products such as nickel ore concentrate, zinc oxide leachate, ferment, starch, alkaline residue, zeolite, copper concentrate.The vertical type blotter press great majority that China uses are from foreign import.But; Along with the history that the vertical type blotter press filter cloth relies on external import has been broken in the appearance of vertical type blotter press filter cloth PS9505-27; Vertical type blotter press filter cloth PS9505-27 adopts big pulling force drafting forming and annular drafting forming; Strengthen dimensional stability, it uses the parallel of filter cloth to adopt tearing film, and it is powerful to increase broadwise.But, but the initial stage design time did not use tearing film to do parallel, once attempted with polypropylene filament yarn as parallel, and the product that weaves at last is soft, but stiffness is not good, and filter effect and filter cloth in the past do not have obvious effects by comparison.
Summary of the invention
In view of the defective that prior art exists, the purpose of the utility model is to provide a kind of upright pressure type filter special-purpose filter cloth, and it adopts tearing film to do parallel, is suitable for vertical type blotter press, increases latitudinal strength.
For realizing above-mentioned purpose; The technical solution that the utility model adopted is: the special-purpose filter cloth of upright pressure type filter; It is weaved by warp and parallel and forms, and parallel is by multifilament, and warp is a monofilament; Employing should be that 3/1 1/3 complex tissue warps adopt polypropylene fibre multifilament composition, and the specification of said multifilament is the 750D/1*3 polypropylene filament yarn.Parallel adopts the tearing film composition, and the specification of said tearing film is diameter 1500D.Said multifilament concentrates on two surfaces up and down of filter cloth, and tearing film concentrates on the centre of filter cloth.
Said filter cloth is through close 72, filling density 27, grammes per square metre 1200, thickness 1.8.
After adopting such scheme, compared with prior art have following beneficial effect: adopt multifilament and tearing film to interweave, multifilament floats on the whole cloth cover fully; Played good crown_interception; When material entered into fabric, because the inside of fabric is tearing film entirely, tearing film had good transparent performance; So just both reach good filter effect, prolonged the service life of filter cloth again.Parallel adopts tearing film in addition, makes the stiffness of filter cloth touch the mark, and rub proofness is qualified, and cloth style is full, meets the instructions for use of vertical type blotter press; And 3/1 1/3 complex tissue method for weaving, the benefit of this kind method are that fabric face floats long line length, and cloth cover is bright and clean.The transparent performance of monofilament is splendid, and material can pass through smoothly, and is not residual in cloth, do not influence the service life of cloth.

Fig. 2 is the institutional framework sketch map of the special-purpose filter cloth of vertical type blotter press.
Among the figure: l, parallel, 2, warp.
The specific embodiment
For understanding the special-purpose filter cloth of upright pressure type filter in depth, in conjunction with Fig. 1, Fig. 2 explains as follows:
The special-purpose filter cloth of upright pressure type filter, it is weaved by warp 2 and parallel 1 and forms, and parallel 1 is by multifilament, and warp 2 is a monofilament, and employing should be that 3/1 1/3 complex tissue warps 2 adopt polypropylene fibre multifilament composition, the specification of said multifilament is the 750D/1*3 polypropylene filament yarn.Parallel 1 adopts the tearing film composition, and the specification of said tearing film multifilament is diameter 1500D.Said multifilament concentrates on two surfaces up and down of filter cloth, and tearing film concentrates on the centre of filter cloth.
Said filter cloth is through close 72, filling density 27, grammes per square metre 1200, thickness 1.8.
Claims (2)
1. the special-purpose filter cloth of upright pressure type filter, it is weaved by warp and parallel and forms, and parallel is by multifilament, and warp is a monofilament, it is characterized in that: adopt 3/1 1/3 complex tissue warps to adopt polypropylene fibre multifilament composition, the specification of said multifilament is the 750D/1*3 polypropylene filament yarn; Parallel adopts the tearing film composition, and the specification of said tearing film is diameter 1500D; Said multifilament concentrates on two surfaces up and down of filter cloth, and tearing film concentrates on the centre of filter cloth.
