Abstract
The utility model relates to a kind of belt-type filter cloth being applied to belt vacuum filter.Described filter cloth comprises two-layer up and down, worked out by the upper strata monofilament weft yarns of diameter to be the upper strata monofilament warp of 0.3mm and diameter be 0.3mm in upper strata; Lower floor is worked out by lower floor's monofilament weft yarns of diameter to be lower floor's monofilament warp of 0.5mm and diameter be 0.5mm.This product (high temperature, strong acid, highly basic, easy crystallization) when environment for use is severe especially uses and within more than 30 days, does not block, does not give a discount, do not shrink.
Description
Technical field
The utility model relates to a kind of filter cloth, especially a kind of belt-type filter cloth being applicable to wide cut vacuum band-type filter machine.
Background technology
The filter cloth of now conventional wide cut vacuum band-type filter machine, the quick Separation of Solid and Liquid workshop section of aluminium oxide uses, soluble in strong alkali solution, filter cloth easily shrinks in the solution, raw material easy crystallization in filter cloth forms blocking, filter cloth hardening causing is fractureed, makes the filter cloth life-span equal to 10 days.The quick separating production line of middle aluminium Company Shanxi Branch experiment once used tens kinds of filter cloths to test, last 5 years and test tens kinds of filter cloths, but because working environment is severe especially, or above difficulty cannot be overcome, become those skilled in the art and be badly in need of solving still still unsolved technical barrier always.
Utility model content
The utility model, for deficiency of the prior art, provides a kind of long service life, corrosion-resistant, easy cleaning, anti-shrinkage, the filter cloth that do not give a discount.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals, a kind of belt-type filter cloth being applied to wide cut belt vacuum filter, comprising two-layer up and down, worked out by the upper strata monofilament weft yarns of diameter to be the upper strata monofilament warp of 0.3mm and diameter be 0.3mm in upper strata; Lower floor is worked out by lower floor's monofilament weft yarns of diameter to be lower floor's monofilament warp of 0.5mm and diameter be 0.5mm.
Preferably, described upper strata forms broadwise to be 5/1 warp-wise be 7/1 herringbone oblique, described lower floor forms broadwise to be 8/1 warp-wise be 11/1 herringbone oblique.
Preferably, described upper strata monofilament weft yarns is polypropylene, and upper strata monofilament warp is polyamide, and lower floor's monofilament weft yarns is polypropylene, and lower floor's monofilament warp is polytetrafluoroethylene (PTFE).
Preferably, the density of described filter cloth warp thread is 140 pieces/inch.
Preferably, the density of described filter cloth weft yarn is 60 pieces/inch.
Preferably, described filter cloth adopts technique of gaiting to be prepared from conjunction with this figure of line.
Preferably, described filter cloth upper strata adopts 45-46 root polypropylene upper layer weft yarns and 112-116 root polypropylene top line repeated overlapping to work out.
Preferably, described filter cloth lower floor adopts 14-15 root polyamide lower floor's weft yarn and 24-28 root polytetrafluoroethylene (PTFE) lower layer warp yarns repeated overlapping to work out.
Further, described filter cloth is applied to belt vacuum filter.
Compared with prior art, lower floor's monofilament weft yarns is polytetrafluoroethylene PTFE, and its intensity is high, and wear-resisting acid and alkali-resistance is high temperature resistant, does not shrink; Lower floor's monofilament warp is poly-third ethene PP, resistance to highly basic, and intensity is high, easily shapes, and not easily gives a discount; Upper strata monofilament weft yarns is polypropylene PP; Upper strata monofilament warp is polyamide PA, and high temperature-resistant acid-resistant is alkaline-resisting, smooth surface.Because material that levels is used is acid and alkali-resistance, so more corrosion-resistant in aluminium oxide quick separating workshop section; And the utility model silk thread used is monofilament lines, monofilament lines relative to two-wire due to just single single line, liquid charging stock can permeate down in the gap between monofilament lines gradually, can not block, and cleaning up is more prone to; Lower floor's monofilament weft yarns is that polytetrafluoroethylene PTFE does not shrink, and lower floor's monofilament warp is easily shaped for poly-third ethene PP, not easily gives a discount, these characteristics determine product of the present utility model can anti-shrinkage, do not give a discount, reach 30 days service life.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further explained.
Embodiment 1:
A kind of belt-type filter cloth being applied to wide cut belt vacuum filter described in the utility model embodiment, cross section of the present utility model as shown in Figure 1, described filter cloth comprises two-layer up and down, worked out by the upper strata monofilament weft yarns 2 of diameter to be the upper strata monofilament warp 4 of 0.3mm and diameter be 0.3mm in upper strata; Lower floor is worked out by lower floor's monofilament weft yarns 1 of diameter to be lower floor's monofilament warp 3 of 0.5mm and diameter be 0.5mm.
Due to levels all be monofilament, do not have multifilament or multifibres group into a line, decrease spot and stay possibility on filter cloth, decrease discounting, cleaning up is more convenient.
Embodiment 2:
Be applied to a belt-type filter cloth for wide cut belt vacuum filter, described filter cloth comprises two-layer up and down, worked out by the upper strata monofilament weft yarns 2 of diameter to be the upper strata monofilament warp 4 of 0.3mm and diameter be 0.3mm in upper strata; Lower floor is worked out by lower floor's monofilament weft yarns 1 of diameter to be lower floor's monofilament warp 3 of 0.5mm and diameter be 0.5mm, and the density on wherein said filter cloth upper strata is 140 pieces/inch, and the density of described filter cloth lower floor is 60 pieces/inch.
Described filter cloth upper strata adopts 45 root polypropylene upper layer weft yarns and 112 root polypropylene top lines, form broadwise to be 5/1 warp-wise be 7/1 herringbone oblique;
Described filter cloth lower floor adopts 15 polyamide lower floor weft yarns and 28 polytetrafluoroethylene (PTFE) lower layer warp yarns, form broadwise to be 8/1 warp-wise be 11/1 herringbone oblique.
Embodiment 3:
Substantially the same manner as Example 2, unlike: described filter cloth upper strata adopts 46 root polypropylene upper layer weft yarns and 116 root polypropylene top lines, form broadwise to be 5/1 warp-wise be 7/1 herringbone oblique;
Described filter cloth lower floor adopts 14 polyamide lower floor weft yarns and 24 polytetrafluoroethylene (PTFE) lower layer warp yarns, form broadwise to be 8/1 warp-wise be 11/1 herringbone oblique.
Lower floor's monofilament weft yarns is polytetrafluoroethylene PTFE, and its intensity is high, and wear-resisting acid and alkali-resistance is high temperature resistant, does not shrink; Lower floor's monofilament warp is poly-third ethene PP, resistance to highly basic, and intensity is high, easily shapes, and not easily gives a discount; Upper strata monofilament weft yarns is polypropylene PP; Upper strata monofilament warp is polyamide PA, and high temperature-resistant acid-resistant is alkaline-resisting, smooth surface.Because material that levels is used is acid and alkali-resistance, so more corrosion-resistant in aluminium oxide quick separating workshop section; Lower floor's monofilament weft yarns is that polytetrafluoroethylene PTFE does not shrink, and lower floor's monofilament warp is easily shaped for poly-third ethene PP, not easily gives a discount, these characteristics determine product of the present utility model can anti-shrinkage, do not give a discount, reach 30 days service life.
Only as described above, be only preferred embodiment of the present utility model, such as professional who are familiar with this art.After understanding technological means of the present utility model, natural energy, according to actual needs, is changed under instruction of the present utility model.Therefore all equal changes of doing according to the utility model claim and modification, all should still belong in scope that the utility model patent contains.
