Description
Technical field
The utility model relates to a kind of filter cloth, particularly relates to a kind of Separation of Solid and Liquid woven filter cloth that use, that effective filtration area is big.
Background technology
Filtration is one of liquid-solid separation unit operation that often adopts in the Chemical Manufacture, it is to add outside under the effect of pressure difference, makes liquid-solid mixture flow through porous media (filter cloth), and solid particle is filtered cloth and holds back, liquid is the hole by filter cloth then, thereby realizes the purpose that liquid-solid two-phase separates.Filtration plays an important role in solving resource, the energy and environmental protection three big problems.
Filter plant commonly used mainly is a filter press, and it mainly contains plate and frame type filter-press, chamber filter press and belt filter press.Their operation principle is identical with basic structure, mainly reaches the effect of filtration by pressure and filter cloth.
Filter cloth is a kind of filter medium, directly influences filter effect, and it can be that woven cloths also can be a non-weaving cloth.Existing chemical fibre filter cloth comprises single multifilament of monofilament filter cloth, multifilament filter cloth, film and fabric compound filter cloth and No. 00204517.1 patent disclosure filter cloth that interweaves.The warp of monofilament filter cloth and parallel all are to have monofilament to be made into, and anti-blockage capability is strong, and the rate of filtration is fast, but it is harder, are difficult to be woven into filter cloth closely, are used for filtering the particle diameter larger particles more.The warp of multifilament filter cloth and parallel all are to be formed by the multifilament braiding, because multifilament is soft, easily weave, and can make parallel that higher tight ness rating is arranged, but easily stop up, and resistance is big, and the rate of filtration is slow.Industrial filter cloth is a kind of of industry cloth, and its purposes is quite extensive, in chemical fibre manufacturing industry, petrochemical industry, food production, medicine and the household electrical appliance, nearly all can see.Different purposes has different quality requirements to industrial filter cloth, and we are devoted to study the filtering material of new structure for this reason, is intended to improve its using value, to satisfy the requirement of every profession and trade.
Filter press filter cloth commonly used mostly is monofilament or sandwich construction chemical fibre cloth, at present, most of Woven filter cloth is made up of multifilament, short fiber on the domestic market, tissue mostly is plain weave, twill, satin weave or their variation and interweaves, and all is monolayer organization, surfacing.Previous patent and bibliographical information stress to improve filter efficiency by changing cloth cover institutional framework (as patent 00219092.3) and weaving method more, do not consider to improve filter efficiency by increasing the effective filtration area mode.And " filter cloth " often is composited for multiply cloth or by woven and other class hole materials on the filter press in the past, such as lining cloth so not only can influence selvedge sealing effectiveness, complex operation, use inconvenience, and their surfacing effective filtration areas there is not too big variation.
Conventional filter cloth mostly is the fabric or the compound fabric of single-layered weave structure, the fabric face structure is smooth, filter cloth and filter plate 4 effect (see figure 3)s when filtering, because filter plate 4 is made by several outstanding strong points with the contact-making surface of filter cloth, and the strong point has certain area, then in filter cloth and filter press filter board 4 contact processes for the face face contacts, the part that contacts with filter plate 4 strong points can not play filter effect, only at the groove place of filter plate 4 filtration is arranged.Filter plate 4 contacts the effective filtration area (generally between 1/3～1/4) of the filter cloth that closely reduces to a certain extent with filter cloth, cause filter efficiency to reduce.Therefore reduce contacting of filter cloth and the strong point, could increase the effective filtration area of filter cloth, shortening filtration time, raising filter efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of filter cloth, particularly provide a kind of Separation of Solid and Liquid woven filter cloth that use, that effective filtration area is big, a kind of filter cloth of the present utility model has solved the problem that the woven filter cloth effective filtration area is little and the filtering ability is weak of prior art, has remedied prior art and has filtered ineffective deficiency.
A kind of filter cloth of the present utility model, form by warp and parallel braiding, warp/or parallel under weave at interval some monofilament, formed double-decker, the upper strata is the filter cloth that warp and parallel braiding form, and lower floor is a monofilament, lower floor's monofilament becomes one by braiding and upper strata filter cloth, lower floor's monofilaments becomes skeleton, supports filter cloth, and has reduced the contact area of filter cloth and filter plate.For the nonwoven filter cloth, also can adopt mode of the present utility model to improve effective filtration area.Monofilament is woven under warp or the parallel by certain spacing distance, perhaps is woven in simultaneously under warp and the parallel, and spacing distance under the warp and the spacing distance under the parallel can equate or be unequal.
As optimized technical scheme:
Wherein, aforesaid a kind of filter cloth, the distance at described interval is 10～30mm.
Aforesaid a kind of filter cloth, the diameter of described monofilament are 0.4～2mm.
