Abstract
The utility model relates to a kind of high-accuracy filtration pressure filter cloth, comprise warp thread and weft yarn, warp thread and weft yarn are interweaved, described warp thread is a set of raw material, described weft yarn is a set of raw material, and a described warp thread is folded on three weft yarns, and the both sides of described every root warp thread are equipped with the warp thread adjoined, adjacent warp thread is above respectively to be moved 2 weft yarns and moves down the formal distribution of 2 weft yarns in the both sides of same warp thread, and described weft yarn is a kind of pyrolysis membrane fiber through special processing process; Described warp thread is the one or more kinds of mixing in terylene, polypropylene fibre, nylon, its fiber wire; Described weft yarn is a kind of pyrolysis membrane fiber through special processing process in terylene, polypropylene fibre, nylon or other fiber wire; Described warp thread is multifilament plying warp thread.The utility model weft yarn adopts extraordinary pyrolysis membrane fiber, can increase its filtering accuracy, can improve the broadwise property endured again, solve pure multifilament filter press cloth filtering accuracy relatively low, very property poor, easily crumple, shortcoming that the life-span is low.
Description
Technical field
The utility model relates to a kind of high-accuracy filtration pressure filter cloth, belongs to filter field.
Background technology
Vertical pressure filter cloth is the annular filter cloth of filtration in vertical type blotter press.Existing vertical type pressure filter press cloth, adopts pure multifilament mostly through, weft yarn, or warp thread multifilament weft yarns monofilament is weaved and formed.General multifilament is through the filter press cloth filtering accuracy of weft weaving all more than 10 μm, and the canvas press cloth of less than 10 μm is difficult to produce, service life is shorter or filter efficiency is lower, cannot meet the demand of client.
Utility model content
The utility model, for deficiency, provides a kind of high-accuracy filtration pressure filter cloth, and in order to solve, traditional filter press cloth filtering accuracy is low, the problem of intensity difference.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of high-accuracy filtration pressure filter cloth, comprise warp thread and weft yarn, described warp thread and described weft yarn are interweaved, a described warp thread is folded on three weft yarns, the both sides of described every root warp thread are equipped with the warp thread adjoined, adjacent warp thread respectively the above weft yarn moving 2 or more and the formal distribution moving down 2 or more weft yarns in the both sides of same warp thread, the described weft yarn number being distributed in the upper and lower both sides of warp thread is identical, and described weft yarn is a kind of pyrolysis membrane fiber through special processing process.
In the utility model, special processing process refers to that first fiber is processed into certain thickness monolithic fiber, and fiber has certain width, in high temperature environments sheet yarn is carried out that transverse direction is random tears simultaneously, the webbed a kind of fiber of shape.
As further optimization of the present utility model, described warp thread is the one or more kinds of mixing in terylene, polypropylene fibre, nylon, its fiber wire.
As further optimization of the present utility model, described weft yarn is a kind of pyrolysis membrane fiber through special processing process in terylene, polypropylene fibre, nylon, other fiber wire.
As further optimization of the present utility model, described warp thread be multifilament plying warp thread, sub-thread or multiply can be divided into, and apolegamy with " S ", " Z " and direction, configure the different twists simultaneously;
The beneficial effects of the utility model are: the utility model weft yarn adopts can increase its filtering accuracy, can improve the broadwise property endured again, solve pure multifilament filter press cloth filtering accuracy relatively low, very property poor, easily crumple, shortcoming that the life-span is low; Be widely used in the isolated by filtration in the fields such as environmental protection, chemical industry, mine, smelting, fertilizer, food.

Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
The utility model relates to a kind of high-accuracy filtration pressure filter cloth, comprise warp thread 2 and weft yarn 1, described warp thread 2 is interweaved with described weft yarn 1, a described warp thread 2 is folded on three weft yarns 1, the both sides of described every root warp thread 2 are equipped with the warp thread 2 adjoined, adjacent warp thread 2 is distributed in the two sides of same weft yarn 1 respectively, and described weft yarn 1 is tearing film fiber.
Described warp thread 2 is the one or more kinds of mixing in terylene, polypropylene fibre, nylon, its fiber wire.
Described weft yarn 1 is a kind of pyrolysis membrane fiber through special processing process in terylene, polypropylene fibre, nylon, its fiber wire.
Described warp thread 2 be multifilament plying warp thread, sub-thread or multiply can be divided into, and apolegamy with " S ", " Z " and direction, configure the different twists simultaneously;
The utility model adopts multifilament plying warp thread 2, pyrolysis membrane fiber weft yarn 1 as filter cloth secondary filter and strength layer, enhance the powerful and ABRASION RESISTANCE through broadwise tension of filter press cloth, improve the broadwise very row of filter press cloth, avoid distortion that filter cloth is in operation simultaneously and crumple.Material is one or more the mixing in terylene, polypropylene fibre, nylon or its fiber wire, this filter press cloth is the ring-like filter press cloth playing isolated by filtration effect in filter press, filter cloth covers on the filter plate of filter press, by feed pipe by the storage bin on product pump entrance pressure filter cloth, by the pressurization of upper and lower increased pressure board, liquid in material is carried out squeezing and getting rid of, thus reaches the filter effect of high-efficiency and continuous.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (4)
1. a high-accuracy filtration pressure filter cloth, comprise warp thread and weft yarn, described warp thread and described weft yarn are interweaved, it is characterized in that: the both sides of described every root warp thread are equipped with the warp thread adjoined, adjacent warp thread respectively the above formal distribution moving 2 or more weft yarns and move down 2 or more weft yarns in the both sides of same warp thread, the described weft yarn number being distributed in the upper and lower both sides of warp thread is identical, described warp thread is multifilament plying warp thread, warp thread is by sub-thread or multiply, and being equipped with " S " or " Z " to different twist directions, the different twists etc. process.
