Description

A kind of novel antistatic filter screen

Technical field

The utility model is related to filtration art, more specifically to a kind of novel antistatic filter screen.

Background technology

Synthetic fibers filter screen has the performances such as acidproof, alkaline-resisting, heatproof, wear-resisting, is mainly used for mining industry, oil, chemical industry, food The industries such as product, medicine, machine-building.But synthetic fibers filter screen holds easy to produce static electricity, meeting adsorption filtration object in filter process, Influence filter effect.At present, all it is to filter top line of the net warp-wise or broadwise arranged for interval metal wire in synthetic fibers, reaches electrostatic Purpose, formed Anti-static filter screen.

The not gentle unequal bad phenomenon in mesh gap of wire side easily occurs for the filter screen of this implanted metal monofilament.Due to The extensibility of metal monofilament is far below the extensibility of monofilament polyester, and shrinking percentage when being heated is there are great difference, so having served as When strainer is heated, fold can occur naturally for strainer wire side；On the other hand, since the toughness and elasticity of metal monofilament are not so good as polyester Monofilament, after strainer, which crimps, to be folded and tile again, monofilament polyester is replied easily, and metal monofilament is difficult to reply pervious shape, It is uneven it will cause wire side.Now also someone inserts carbon fiber wire to reach anlistatig effect, still, carbon fiber wire in strainer Heat shrinkability very little, be very different with monofilament polyester, the still easy fold of wire side, cause mesh gap uneven, influenced Performance is filtered, and carbon fiber wire is more crisp, is easily broken off, and what filter screen typically produced in rolls, the process for crimping strainer is easy Carbon fiber wire is caused to be broken, strainer is so as to losing antistatic performance.

In addition, existing strainer is woven by warp and weft, and between latitude and longitude and it is not fixed, every time during cleaning, The impurity scraped clean that will be sticked to scraper plate on strainer is required for, This move easily changes mesh gap size, causes to filter The reduction of precision.

The content of the invention

1. utility model technical problems to be solved

The purpose of the utility model is to overcome wire side fold existing for existing antistatic filter screen and mesh gap is big Small unfixed deficiency provides a kind of novel antistatic filter screen.Using the technical solution of the utility model, warp and weft The bonding fixation of cross-point is woven, areola is fixed, and filtering accuracy is ensured, conductive monofilament is being realized using plating carbon nylon yarn While antistatic property, the planarization of strainer wire side ensure that, evenly, filtering accuracy is more reliable in sieve meshes gap.

2. technical solution

In order to achieve the above objectives, technical solution provided by the utility model is：

A kind of novel antistatic filter screen of the utility model, including the warp and latitude mutually woven and cross-point is bonding Line, using core-skin type composite monofilament, the cortex and sandwich layer of the core-skin type composite monofilament are the warp and weft Polyester, and the fusing point of cortex polyester is less than the fusing point of sandwich layer polyester, is all equipped at intervals between the warp and weft conductive single Silk, the conductive monofilament is using plating carbon nylon yarn.

Further, the conductive monofilament spaced set.

3. advantageous effect

Using technical solution provided by the utility model, compared with existing known technology, have the advantages that：

(1) a kind of novel antistatic filter screen of the utility model, the bonding fixation of braiding cross-point of warp and weft, Areola is fixed, and filtering accuracy is ensured.

(2) a kind of novel antistatic filter screen of the utility model, warp and weft are using core-skin type composite monofilament, skin The fusing point of the cortex polyester of core pattern composite monofilament is less than the fusing point of sandwich layer polyester, convenient for cortex hot melting cohesion, without influencing core The performance of layer.

(3) a kind of novel antistatic filter screen of the utility model, conductive monofilament are anti-quiet realizing using plating carbon nylon yarn While electrical property, the planarization of strainer wire side ensure that, evenly, filtering accuracy is more reliable in sieve meshes gap.

(4) a kind of novel antistatic filter screen of the utility model is all equipped at intervals with conductive monofilament between warp and weft, The fracture of local conductive monofilament does not interfere with the antistatic property of strainer entirety.

Specific embodiment

To further appreciate that the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments.

Embodiment 1

With reference to Fig. 1 and Fig. 2, a kind of novel antistatic filter screen of the present embodiment, including mutually weaving and cross-point mutually glues The warp 1 of knot and weft 2.Warp 1 and weft 2 are using core-skin type composite monofilament, the cortex and sandwich layer of core-skin type composite monofilament It is polyester, and the fusing point of cortex polyester is less than the fusing point of sandwich layer polyester, preferably, the fusing point of cortex polyester is less than sandwich layer polyester About 20 DEG C of fusing point be preferred, when bonding the cross-point of warp 1 and weft 2, hot melting temperature is higher than the fusing point of cortex polyester, and is less than The fusing point of sandwich layer polyester.

Conductive monofilament 3 is all equipped at intervals between warp 1 and weft 2, such as shown in Fig. 2, one is set every two warps 1 Conductive monofilament 3, in order to improve the planarization of strainer wire side and the anlistatig stability of strainer, 3 spaced set (this of conductive monofilament In spaced set refer to two adjacent conductions between the spacing of two adjacent conductive monofilaments 3 between warp and weft The spacing of monofilament 3 is equal).Certainly, conductive monofilament 3 is also arranged at intervals every two wefts 2, antistatic property is more preferable, locally leads The fracture of electric monofilament 3 does not interfere with the antistatic property of strainer entirety.

The conductive monofilament 3 of the present embodiment is using plating carbon nylon yarn, as shown in figure 3, sandwich layer uses nylon yarn 31, nylon yarn 31 Outer surface be coated with carbon-coating, certainly, above-mentioned plating carbon nylon yarn may be alternatively provided as that sandwich layer is nylon yarn 31 and cortex is carbon-coating 32 Core-skin type composite monofilament.The extensibility and percent thermal shrinkage and monofilament polyester of nylon yarn 31 are closer, so when strainer is heated, Its wire side will not generate fold, and the carbon-coating 32 that surface is set is electrically conductive.The filter screen of the present embodiment is realizing antistatic property While, it ensure that the planarization of strainer wire side, evenly, filtering accuracy is more reliable in sieve meshes gap.

A kind of novel antistatic filter screen of the utility model, the bonding fixation of braiding cross-point of warp and weft, net Gap is fixed, and filtering accuracy is ensured, conductive monofilament while antistatic property is realized, ensure that using plating carbon nylon yarn The planarization of strainer wire side, evenly, filtering accuracy is more reliable in sieve meshes gap.

Schematically the utility model and embodiments thereof are described above, this describes no restricted, attached drawing Shown in be also the utility model one of embodiment, actual structure is not limited thereto.So if this field Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, without creatively designing The frame mode similar to the technical solution and embodiment, all should belong to the protection range of the utility model.
