Problems solved by technology

In addition, the non-woven needle-punched filter cloth made of chemical fibers or natural fibers has the advantages of high filtration efficiency and small pressure difference in the filtration system due to its own three-dimensional structure advantages, but this The strength of this kind of non-woven filter cloth is extremely low, and the service life is very short
And so far, no good solution has been proposed in the field of liquid / solid separation and filtration of industrial fluids

Embodiment Construction

[0015] Embodiments of the present invention are described in detail below, examples of which are in the appended figure 1 and 2 shown in . The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0016] In the present invention, a kind of non-woven filter cloth and its manufacturing method are provided, and described filter cloth is made up of two-layer structure, namely: supporting layer (attached figure 1 2) and filter layer (attached figure 1 4). Its supporting layer is a woven mesh structure interwoven with warp and weft (as attached figure 2 shown, with figure 2 1 in is the meridian direction, attached figure 2 2 in the latitudinal direction). The warp and weft interlaced woven mesh support layer only plays the role of support and reinforcement, so the density of its warp and weft interweaving is as small as possible under the premise of en...

Abstract

A manufacture method for nonwoven filter cloth is characterized by consisting of a two-layer structure comprising a supporting layer and a filter layer. The supporting layer is woven net structure by weaving warps and wefts, and the filter layer is a nonwoven fabric structure formed by needling. According to the manufacture method for the nonwoven filter cloth, the nonwoven fabric formed by needling and the woven net by weaving warps and wefts are combined into a whole through a needling technology and equipment, so that the novel filter cloth is constructed. Meanwhile, the surface of the non-woven fabric of the filtering layer is calendered or sintered, so that the surface is smooth, flat and firm, and a filter cake can be removed smoothly.

Description

technical field [0001] The present invention relates to a manufacturing method of a non-woven filter cloth, in particular, the present invention relates to mining and beneficiation, sorting and extraction of co- and associated minerals, liquid / solid separation of industrial fluids and material purification for mineral resources industry to improve resource recovery and utilization rate Or recycle the required filter cloth. Background technique [0002] At present, industrial woven and non-woven textile fiber filter cloths are widely used in mining, beneficiation, and dehydration of mineral resource industries; sorting and extraction of co- and associated minerals, coal washing, petroleum processing in refineries, industrial fluid liquid / solid separation, In the filtration process of material purification or recovery. Most of the woven filter cloths used in industrial filters are conventional woven filter cloths made of chemical fibers or natural fibers, and there are also a...
