Abstract
The utility model discloses non-framework filter material which is planar needled felt filter material formed by overlaying a plurality of fiber layers of terylene or polypropylene fiber with filter material fiber specification of 2 to 2.5D*76 mm to 81 mm, spaces formed among all layers of filter material fiber are arranged in a staggered manner, so as to form a three-dimensional structure. Base cloth is not arranged in the non-framework filter material, strength and elongation at break of the filter material are improved by fully utilizing the fiber, the porosity is large, the air permeability is good, the load capacity of equipment is improved, the pressure loss and power consumption can be reduced, Compared with the filter material with base cloth, the porosity is improved by 1% to 3%, the air permeability is high, the material loss is low, the cost is saved, the dust capturing efficiency is high, and the gas emission concentration is low.
Description
Technical field
The utility model relates to a kind of filtering material of textile technology field, particularly relates to a kind of novel skeletonless filter material.
Background technology
Needle punched filter material is widely used in the process application of multiple industries such as metallurgy, chemical industry, building materials, smelting, generating, pottery, machinery, mine, oil, medicine, dyestuff, food, grain processing, material reclaims, fields such as the liquid-solid separation of smoke and dust treatment are desirable gas purification filtering material and Separation of Solid and Liquid media.
Traditional needle punched filter material preparation method is: the fibrage that the folded net of combing is made is layered on the base cloth that weaves, use the needing machine repeated puncture, fibrage and base cloth are combined securely, form three-dimensional structure, thorn filtrate well is through hot pressing, the coating of singing or overlay film, finalize the design behind a series of arranging processes, make it typing and improve its strainability, this filtrate improves intensity and elongation at break by base cloth, selecting fiber dimensious for use is 2.5D * 51mm, base cloth in the above-mentioned preparation method reduces the fibre web porosity, base cloth spinning feed consumption 5%, the feed consumption 5% of weaving cotton cloth, gas permeability and intensity are not high.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model provides a kind of novel skeletonless filter material, adopt short fiber material, fiber dimensious is between 2～2.5D * 76mm～81mm, middle no base cloth, utilize fiber to improve the intensity and the elongation at break of filtrate fully, porosity is big, and good permeability can improve the apparatus of load ability and reduce crushing and energy consumption, it is low to decrease material, saves cost.
The technical scheme that the utility model solution prior art weak point is taked is: a kind of skeletonless filter material, comprise the filtrate fiber, it is characterized in that: filtrate is that specification is that the terylene reticular fibre layer multi-layer of 2～2.5D * 76mm～81mm laminates and forms the plane filtrate by the filtrate fiber, form the space between each metafiltration material fiber and be staggered, constitute three-dimensional structure.
Described filtrate is terylene or polypropylene fibre Nomex.
This skeletonless filter material, through the shredding of fiber, combing, lapping, acupuncture and after typing handle, utilize fiber to improve the intensity and the elongation at break of filtrate, middle no base cloth fully.
The beneficial effects of the utility model are: utilize fiber to improve the intensity and the elongation at break of filtrate fully, middle no base cloth, porosity is big, good permeability, can improve the apparatus of load ability and reduce crushing and energy consumption, improve 1～3% than traditional base cloth filtrate porosity that has, ventilative higher, it is low to decrease material, saves cost.Utilization is staggered, and the space is distributed with thin short fiber filter gas, and voidage can reach more than 70%.The efficiency of seizing dust height, the gas concentration of emission is low.Actual measurement shows that the efficient of filter 23 25 order talcum powder (about meso-position radius 7.5 μ m) can reach 99.9～99.99%, improves an order of magnitude than flannelette.The gas concentration of emission is lower than state-set standard widely.
Description of drawings
Fig. 1 is the utility model cross-sectional view.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
A kind of skeletonless filter material of the utility model as shown in Figure 1, filtrate is that specification is that the terylene of 2～2.5D * 76mm～81mm or polypropylene fibre arlt's strata 1 multilayer laminate and form the plane filtrate by the filtrate fiber, form the space between each metafiltration material fiber and be staggered, constitute three-dimensional structure.This skeletonless filter material, through the shredding of fiber, combing, lapping, acupuncture and after typing handle, utilize fiber to improve the intensity and the elongation at break of filtrate, middle no base cloth fully.
The preparation method of the utility model skeletonless filter material is, earlier fiber opening is become the ultimate fibre state, the specification of selected fiber is between 2～2.5D * 76mm～81mm, the specification of fiber of the prior art is generally 2.5D * 51mm or greater than this specification, the filtrate voidage of its making is limited, influences air penetrability.Filtrate of the present utility model is owing to adopt above-mentioned shorter fiber, and porosity is big, and good permeability can improve the apparatus of load ability and reduce crushing and energy consumption.Fiber is preferably the fiber in above-mentioned specification of terylene, polypropylene fibre or other materials, forms the space between the fiber and is staggered, and constitutes three-dimensional structure, and utilization is staggered, the thin short fiber filter gas that the space distributes, and voidage is higher.Then that the fiber combing is submissive, it is short-tempered to remove, and the fiber after the combing is more neat smooth.Again single layer fibre in layer is paved into fleece, middle no base cloth, no base cloth ratio have the base cloth porosity to improve 1～3%, and be ventilative higher.Tradition filtrate base cloth spinning feed consumption 5%, the feed consumption 5% of weaving cotton cloth has not lacked this loss and there is base cloth.Handle through acupuncture then, form pinprick 2, allow fiber be staggered in to form the space together be staggered, constitute three-dimensional structure.To sting good filtrate again through hot pressing, behind a series of arranging processes of filming, finalize the design, and make it typing and improve its strainability.
