Abstract
The utility model discloses a multi-fiber multi-layer compound acupuncture non-woven filtration cloth, which is formed through compounding a central base fabric and a plurality of layers of multi-fiber, wherein the fibers are divided into surface layer fibers and bottom layer fibers which are respectively arranged on the upper and the lower layer of a base fabric layer. The surface layer fibers are fine fibers with the specifications being (1.5-15) D usually; and the bottom layer fibers are crude fibers with the specifications being (1.5-30) D usually, therefore, horn-shaped holes tapering from bottom to top are formed, and the solid and liquid separation can be realized rapidly.
Description
Technical field
The utility model relates to multifilament multi-layer two-piece needle non-woven filtering cloth, relates in particular to a kind of multifilament multi-layer two-piece needle non-woven filtering cloth that can realize Separation of Solid and Liquid and can satisfy requirement of band filter high strength and filter effect.
Background technology
At present, the base cloth of most of Nomex filter cloth is short fiber or long filament base cloth on the domestic market, thin thickness, and Gram Mass is little, and such cloth is used for gas solid separation more; And woven belt filter cloth is made up of long filament, short fiber, weaves the filter cloth that forms through loom.The equal metal surface of Nomex filter cloth and woven belt filter cloth filters, it is the unit operations that utilizes filter medium that solid and liquid or solid are separated with gas, but in use there is following problem in common Nomex filter cloth: 1. intensity is low, is easily broken when using on the belt filter; 2. fabric width is narrow, and the belt filter uses the filter cloth fabric width at 0.5～4.5m, and common Nomex filter cloth fabric width is generally below 2m; 3. easily stop up, service life is short; 4. the cloth cover stiffness is lower, and is easily pleating.And in use there is following problem in woven belt filter cloth: 1. porosity is low; 2. filtering velocity is slow; 3. filter cake and filter cloth stripping performance are poor, and power of regeneration is poor.The appearance of multifilament multi-layer two-piece needle non-woven filtering cloth has remedied the defective of general acupuncture felt filter cloth and woven belt filter cloth.
Summary of the invention
For solving problem and the defective that exists in above-mentioned, the utility model provides a kind of multifilament multi-layer two-piece needle non-woven filtering cloth, and this filter cloth not only intensity can satisfy the requirement of belt filter, can also solve the slow phenomenon of woven belt filter cloth filtering velocity.
The utility model is achieved through the following technical solutions:
A kind of multifilament multi-layer two-piece needle non-woven filtering cloth that the utility model is related comprises:
Adopt the compound formation of central base cloth and multifilament multi-layer, described fiber is divided into surface fibre and bottom fiber, and described surface fibre and bottom fiber lay respectively at the levels of a base cloth layer.
Dawn fibrage in one also is set between described surface fibre and the base cloth layer.
Described base cloth is the monofilament base cloth, and its specification is ∮ 0.2/2*2; Described surface fibre is a fine fibre, and its specification is 1.5D～15D; Described bottom fiber is that its specification of crude fibre is 1.5D～30D.
Described fine fibre and crude fibre form up-small and down-big horn-like hole.
Described monofilament base cloth is nylon monofilament or polypropylene filament.
The beneficial effect of the technical scheme that the utility model provides is:
The intensity height, the surface smoothness height can satisfy the requirement of belt filter; And the multifilament multi-layer two-piece needle non-woven filter cloth in use filtering velocity is fast, filtering accuracy is high.
Description of drawings
Fig. 1 is the surface fibre structural representation of multifilament multi-layer two-piece needle non-woven filtering cloth;
Fig. 2 is the bottom fiber structural representation of multifilament multi-layer two-piece needle non-woven filtering cloth;
Fig. 3 is a multifilament multi-layer two-piece needle non-woven filtering cloth base cloth organization chart commonly used;
Fig. 4 is the cross-sectional view of multifilament multi-layer two-piece needle non-woven filtering cloth.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, Fig. 2, be surface fibre and bottom fiber structure, this surface fibre is selected the fiber at thin dawn for use, its specification is generally 1.5D～15D, and handle through adding hot calendering, make the filter cloth smooth surface, voidage is big, hole is little, in the Separation of Solid and Liquid process, material particles is difficult for entering the inside of filter cloth, is difficult for stopping up; Described bottom fiber is selected crude fibre for use, and specification is generally 1.5D～30D, and the described filter cloth top layer fine fibre that is distributed in forms up-small and down-big aperture structure with the crude fibre that is distributed in the filter cloth nexine, is easy to tackle solid particle and is difficult for stopping up; And can select the fiber of different size according to the granular size of material for use, make the filtering accuracy scope of this series products big, applied range.
Referring to Fig. 3, be the warp of base cloth longitudinally, horizontal is the parallel of base cloth.The specification that its graticule is commonly used is a ∮ 0.2/2*2 nylon monofilament, and tissue mostly is plain weave, commonly used through close be that 17 (roots/inch), filling density are 15 (roots/inch), different filter requirement of strength differences, its base cloth also has adjustment.
Referring to Fig. 4, fine fibre 40 concentrates on the surface of filter cloth, crude fibre 43 concentrates on the bottom of filter cloth, remove in the fine fibre 40 and the centre of crude fibre 43 and to be provided with the base cloth layer (this base cloth is monofilament plying plain weave base cloths 42 such as polyamide fibre/polypropylene fibre), the fiber 41 of a fiber thickness between fine fibre and crude fibre in addition between base cloth layer and fine fibre.Wherein, fine fibre 40 tops are working face, 43 of crude fibres are reverse side, in use, material is added on the working face, and by applying malleation or negative pressure, the particle less than the filter cloth aperture in the material passes the filter cloth infiltration in the past, particle greater than the filter cloth aperture is tackled on the surface of filter cloth by fine rule, thereby realizes the separation of solid-liquid.
Present embodiment top layer fine count fiber interception filter material, middle monofilament plying plain weave base cloth increases the intensity of filter cloth, the bottom coarse denier fiber plays to be increased filter cloth intensity and makes the fine particle that passes surface fibre fast by this zone, be difficult for resulting in blockage, thereby realize the purpose of Separation of Solid and Liquid fast.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
