Description
Technical Field
The utility model belongs to the technical field of powdered ore pressure filter (patent classification number B01D 25/12), a filter cloth of pressure filter is related to.
Background
The filter press is a pressurized filtering device with multiple filtering chambers operated intermittently, and is suitable for solid-liquid separation of various kinds of floating liquid.
An industrial filter cloth, which is a core filter element of a filter press and is woven by warps (lines parallel to a selvedge) and wefts (lines perpendicular to the selvedge); the knitting method (weave structure) includes: plain weave, twill weave, satin weave, non-woven needle-punched molding; the varieties of warp and weft are: monofilament (a filament), multifilament (a filament woven by a plurality of fibers), and split film (a net filament formed by stretching and splitting a film, commonly called a film filament); the silk thread material of filter cloth is mostly polypropylene fibre, dacron, polyamide fibre etc. and polypropylene fibre infiltration, regeneration performance are better, and polypropylene fibre has simple production technology, and the product is cheap, and intensity is high, relative density light advantage such as, is the fourth main variety of synthetic fiber, is the lightest fibre among the common chemical fiber. The polypropylene fibers are in the forms of long fibers, short fibers, bristles, split fibers, hollow fibers, profiled fibers, various composite fibers, nonwoven fabrics and the like. The main application is to manufacture carpet, decorative cloth, furniture cloth, various ropes, strips, fishing nets, oil absorption felts, building reinforcing materials, packaging materials and industrial cloth, such as filter cloth, bag cloth and the like, and the filter cloth is mainly woven by polypropylene fibers and is specially used for a filter press to filter various materials.
The existing white carbon black filter cloth has the following defects: the breaking strength is low, and the service life is short; easy to block and slow in filtering speed; the filter cake is thin and the discharging is slow; seriously affecting the production efficiency and being not beneficial to the promotion of the economic benefit of enterprises.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defect of current filter cloth, solving corresponding technical problem, through the repetition test, provide a polypropylene fibre monofilament white carbon black filter cloth.
The utility model provides an innovation technical scheme that prior art problem adopted is: the polypropylene monofilament white carbon black filter cloth is formed by interweaving warps (warps) and wefts (wefts), eight satin textures with five flyings are used instead, and the surface of the fabric is flat and smooth; the warp is 0.2mm polypropylene monofilament, and the density is 880 yarns/10 cm; the weft is 0.2mm polypropylene monofilament with the density of 410 pieces/10 cm; the filter cloth has long floating length of warp yarns on the surface, small warp tightness deviation on the front and back surfaces of the fabric, increased warp and weft density, high hardness of the finished filter cloth and convenient unloading.
Further, the weft yarns are yarns perpendicular to the selvedges, the diameter of each yarn is 0.2mm, and the density of each yarn is 410 yarns per 10 cm; the warp threads are parallel to the selvedge and have a diameter of 0.2mmThe density is 880 roots/10 cm; the characteristics of polypropylene are: the high-strength high-elongation high-elasticity high-strength high-elasticity high-abrasion-resistance filter cloth has the advantages that the breaking strength of the filter cloth can be improved, and the service life is prolonged; further, the air permeability is 30L/m 2 about/S, the cloth cover structure of the filter cloth is compact, so the hardness of the finished filter cloth is high, and the filter cloth made of the filter cloth is stiff and has high discharging speed and easy discharging.
Furthermore, the weaving method of the warp and the weft adopts eight pieces of five-flying, namely, one circulation arrangement mode of the warp and the weft is that the warp is positioned at the upper seven wefts of the weft, and the warp is positioned at the lower one weft of the weft; the floating length of the warp yarns on the surface of the filter cloth is long, the tightness deviation of the warp yarns on the front side and the back side of the fabric is small, the surface of the fabric is smooth and flat, the warp and weft density is increased, the interception rate is high, the filtering speed is high, the filter cake is not easy to block, the thickness of the filter cake is increased in the same time, and the production efficiency is improved.
The utility model provides a pair of polypropylene fiber monofilament white carbon black filter cloth has advantages such as interception rate height, filter speed are fast, take off the cake easily and unload, long service life, has improved the performance of filter cloth especially in the application of white carbon black trade.
