Description
Technical Field
The invention belongs to the technical field of industrial filter cloth spinning, and relates to filter cloth for a filter press.
Background
The filter press is a general filtering device and is suitable for solid-liquid separation of various suspensions. The filter cloth and the filter plate are core filter elements of the filter press, and the performance of the filter cloth (including trapping, permeation, physical and chemical properties and mechanical properties) determines the precision and the filtration rate of solid-liquid separation and also directly influences the working efficiency of the filter press.
Industrial filter cloth, which is both a filter medium and a seal of an adjacent filter plate, is a core element of a filter press and is woven from warp yarns (threads parallel to the selvedge) and weft yarns (threads perpendicular to the selvedge). The filter cloth has different tissue structures, yarn varieties and materials, so that the performance is different, and the filter cloth is suitable for solid-liquid separation of different suspensions through intermediate tests. 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 carpets, 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 prior beer filter cloth has the following defects: the breaking strength is low, the service life is short, the filter cloth is stiff and does not fit with the filter plate, the filter plate is not easy to be attached, the filter plate is not easy to detach, the production efficiency of the filter press is seriously influenced, and the economic benefit of enterprises is not favorably improved.
Disclosure of Invention
The invention aims to overcome the defects of the existing filter cloth, solve the corresponding technical problems and provide the special filter cloth for the polypropylene monofilament beer.
The technical scheme adopted by the invention for solving the problems in the prior art is as follows: the special filter cloth for the polypropylene monofilament beer is formed by interweaving warp yarns (warps) and weft yarns (wefts), and a weaving method combining double-fabric weave is adopted for cloth cover weave innovation, and is characterized in that: the cloth cover weave uses 2 upper and 2 lower twill plus 1 upper and 1 lower plain weave double weave; the yarns are made of 0.28mm polypropylene monofilaments, the density of warp yarns is 300/10 cm, and the density of weft yarns is 140/10 cm; the warp and weft knitted double-fabric tissue combined filter cloth not only improves the breaking strength of the filter cloth and prolongs the service life, but also improves the flexibility of the filter cloth, so that the filter cloth is more attached to the surface of a filter plate and the filtering efficiency is improved through double innovation of the silk thread type and the knitting method.
Furthermore, the cloth cover organization innovation adopts a 2-up 2-down twill + 1-up 1-down plain weave double-weave weaving method, namely, one circulation arrangement mode of warp and weft of an upper layer weave is that the warp is positioned at the upper layer 2 weft of the weft, one circulation arrangement mode of the warp is positioned at the lower layer 2 weft of the weft and the warp and weft of the upper layer weave is that the warp is positioned at the upper layer 1 weft of the weft, and the warp is positioned at the lower layer 1 weft of the weft, and the two weaving methods are adoptedThe parallel fusion ensures that the filter cloth is soft and not loose, the filter cloth is tightly combined with the surface of the filter plate, and the filtering speed is greatly improved; secondly, the surface of the filter cloth is smooth after high-temperature setting, and the air permeability is (550-2The filtering speed is extremely high and the discharging speed is fast between the/S.
Further, the weft yarns are yarns perpendicular to the cloth edge, the weft yarns are 0.28mm polypropylene monofilaments and have the density of 140 yarns/10 cm; the warp parallel to the selvedge is also polypropylene monofilament with the density of 300 yarns/10 cm and the thickness of 0.28 mm; the characteristics of polypropylene: the polypropylene filter cloth has high strength, large elongation, higher initial modulus and excellent elasticity, so the polypropylene filter cloth has high breaking strength, wear resistance and long service life; in addition, the wet strength of polypropylene is basically equal to dry strength, almost no moisture absorption, but the wicking capability is strong, and water vapor can be transferred through capillaries in the fabric, so that the discharge speed of the filter cloth made of the polypropylene is high, beer contains a large amount of carbonic acid components, the pH value is low, the beer is acidic, and the polypropylene has good resistance to acid and alkali.
The special filter cloth for the polypropylene monofilament beer, provided by the invention, has the advantages of long service life, high filtering speed, high breaking strength, adhesion to the surface of a filter plate and the like, and improves the service performance of the filter cloth, particularly the application in the beer filtering industry.
