Problems solved by technology

[0002] The filter cloth of the commonly used wide-width vacuum belt filter is used in the alumina rapid solid-liquid separation section. It is easy to dissolve in a strong alkaline solution, the filter cloth is easy to shrink in the solution, and the raw material is easy to crystallize in the filter cloth. Clogging makes the filter cloth hard and breaks, making the service life of the filter cloth less than 10 days
The rapid separation production line tested by Chinalco Shanxi Branch has used dozens of filter cloths for experiments. It took 5 years to test dozens of filter cloths. However, due to the extremely harsh working environment, the above difficulties still cannot be overcome, and it has become a technology in the field. Technical problems that need to be solved urgently but have not been solved

Embodiment 1

[0018] A kind of belt type filter cloth that is applied to wide-width belt type vacuum filter described in the embodiment of the present invention, such as figure 1 In the cross-section of the present invention shown, the filter cloth comprises two layers up and down, the upper layer is made of the upper monofilament warp yarn 4 with a diameter of 0.3mm and the upper monofilament weft yarn 2 with a diameter of 0.3mm; The lower layer monofilament warp yarn 3 of 0.5 mm and the lower layer monofilament weft yarn 1 with a diameter of 0.5 mm are woven.

[0019] Since the upper and lower layers are made of monofilament, there is no multifilament or multifilament to form a line, which reduces the possibility of stains remaining on the filter cloth, reduces discounts, and is more convenient to clean.

Embodiment 2

[0021] A belt-type filter cloth applied to a wide-width belt-type vacuum filter, the filter cloth includes upper and lower layers, the upper layer is composed of an upper monofilament warp yarn 4 with a diameter of 0.3mm and an upper monofilament weft yarn 2 with a diameter of 0.3mm Weaving; the lower layer is made up of a lower monofilament warp yarn 3 with a diameter of 0.5mm and a lower monofilament weft yarn 1 with a diameter of 0.5mm, wherein the density of the upper layer of the filter cloth is 140 pieces / inch, and the filter cloth The density of the lower layer is 60 / inch.

[0022] The upper layer of the filter cloth adopts 45 polypropylene upper layer weft yarns and 112 polypropylene upper layer warp yarns to form a herringbone that the weft direction is 5 / 1 and the warp direction is 7 / 1;

[0023] The filter cloth lower layer adopts 15 polyamide lower layer weft yarns and 28 polytetrafluoroethylene lower layer warp yarns to form a herringbone with a weft direction of 8...

Embodiment 3

[0025] It is basically the same as Example 2, except that the upper layer of the filter cloth adopts 46 polypropylene upper layer weft yarns and 116 polypropylene upper layer warp yarns to form a herringbone bias with a weft direction of 5 / 1 and a warp direction of 7 / 1;

[0026] The filter cloth lower layer adopts 14 polyamide lower layer weft yarns and 24 polytetrafluoroethylene lower layer warp yarns to form a herringbone bias with a weft direction of 8 / 1 and a warp direction of 11 / 1.

[0027] The lower monofilament weft yarn is polytetrafluoroethylene PTFE, which has high strength, wear resistance, acid and alkali resistance, high temperature resistance, and no shrinkage; the lower monofilament warp yarn is polypropylene PP, which is resistant to strong alkali, high strength, easy to shape, and not easy to discount; the upper layer monofilament The silk weft yarn is polypropylene PP; the upper monofilament warp yarn is polyamide PA, which is resistant to high temperature, ac...

Abstract

The invention relates to a filter cloth, in particular to a belt filter cloth suitable for a wide-width vacuum belt filter. Described filter cloth comprises upper and lower two layers, and upper strata is to be made up of the upper monofilament warp yarn that diameter is 0.3mm and the upper strata monofilament weft yarn that diameter is 0.3mm; The lower layer of monofilament weft is woven with 0.5mm. This product will not be clogged, discounted or shrunk when used for more than 30 days in particularly harsh environments (high temperature, strong acid, strong alkali, easy to crystallize).
