Technical field

The utility model relates to filter cloth fields, more specifically, it relates to a kind of composite filtering cloth of antistatic.

Background technique

Composite filtering cloth, be the filter cloth one or both sides face made of high molecular material melt-blown or bonding high molecular material and It is made.Composite filtering cloth have it is inexpensive, intensity is high, cross air filtering and water it is high-efficient, strainability be better than cotton filter cloth, energy It is widely used in filtration art, such as the dust bag as dust catcher, or as the filter layer in water purification treatment system.

Currently, be applied in the market the fields such as coal, electric power, waste incineration, chemical industry and smelting iron do not have both simultaneously compared with The composite filtering cloth of good anti-static function and filtering function.

Utility model content

In view of the deficienciess of the prior art, having preferable the purpose of this utility model is to provide a kind of structure is simple The antistatic composite filtering cloth of dedusting function.

To achieve the above object, the utility model provides following technical solution: a kind of antistatic composite filtering cloth, including Filter layer of cloth (1), filter membranous layer (2) and antistatic backing (3), the filtering layer of cloth (1) are weaved by several warps (11) and weft (12) It forms, filter membranous layer (2) are arranged in the dust-collecting face of the filter layer of cloth (1), and the filter membranous layer (2) is arranged far from the surface of filter layer of cloth (1) Antistatic backing (3) passes through bonding connection between the filter layer of cloth (1), filter membranous layer (2) and antistatic backing (3).

By using above-mentioned technical proposal, filter layer of cloth is weaved by several warp and weft, has filter cloth stronger Tensile resistence, long-term greater pressure of bearing are unlikely to deform, prolong its service life, and filter membranous layer is arranged in the dust-collecting face of filter cloth, uses One side film not only saved cost but also dust-collecting face can the lesser particle of filter diameter, have composite filtering cloth preferably Filter effect, prolonged use make filter cloth surface accumulate bisque, generate certain voltage, be easy to produce electrostatic, in filter membranous layer Surface setting antistatic backing can prevent electrostatic from generating, and filter layer of cloth, filter membranous layer and antistatic backing are connected to one by bonding superposition It rises, bonding Joining Technology is simple, and production cost is low.

The utility model is further arranged to: the warp (11) and weft (12) are by nylon fibre or polypropylene filament yarn At least one is constituted.

By using above-mentioned technical proposal, nylon fibre has the advantages of intensity is high, and wearability is good, strong alkali-acid resistance；Third Synthetic fibre long filament has preferable gas permeability, powder filter and pressure filtration effect, utilizes one or both of above two fiber The composite filtering cloth being prepared has preferable durability and filter effect.

The utility model is further arranged to: the filter membranous layer (2) is made of polytetrafluoroethylene (PTFE).

By using above-mentioned technical proposal, polytetrafluoroethylene (PTFE) has high temperature resistant, acid-fast alkali-proof, does not dissolve in various organic solvents The characteristics of, the composite filtering cloth filter efficiency that its overlay film is prepared on filter layer of cloth is high, and good permeability is reusable, With longer service life.

The utility model is further arranged to: the antistatic backing (3) is made of metallic fiber or electrically conductive organic fibre.

By using above-mentioned technical proposal, metallic fiber and electrically conductive organic fibre are equably covered on filter membranous layer, shape At sheet resistance, effectively prevents composite filtering cloth surface and generate electrostatic.

Specific embodiment

The utility model will be further described below with reference to the accompanying drawings and specific embodiments, practical with description and interpretation sheet It is novel, but be not intended to limit the scope of the present invention.

Referring to attached drawing 1 and attached drawing 2, a kind of antistatic composite filtering cloth, including filter layer of cloth 1, filter membranous layer 2 and antistatic backing 3, The filtering layer of cloth 1 is weaved by several warps 11 and weft 12, and warp and weft are by nylon fibre or polypropylene fibre long fibre structure At, or by nylon fibre and polypropylene fibre long fibre is blended forms, warp 11 and 12 infall of weft are connected, the filter layer of cloth Filter membranous layer 2 is arranged in 1 dust-collecting face, and filter membrane is polytetrafluoroethylene film, and polytetrafluoroethylene film can filter 2 microns of partial size of particle, far Antistatic backing 3 is arranged in one side from filter layer of cloth 1.Antistatic backing 3 is made of metal fiber wire or electrically conductive organic fibre, specifically, Metallic fiber is stainless steel fibre, and electrically conductive organic fibre is polyester filament fiber, and stainless steel fibre not only has highly conductive, high lead The performances such as heat, high intensity, high temperature resistant, corrosion-resistant, the also characteristic with chemical fibre, synthetic fibers, polyester filament fiber is nonmetallic There is good antistatic and flame retardant property in fiber, stainless steel fibre perhaps polyester filament or stainless steel fibre and is washed Fiber made of the long silk blend of synthetic fibre is as antistatic backing, so that the utility model composite filtering cloth overall performance is promoted, filter layer of cloth 1, by bonding superposition connection between filter membranous layer 2 and antistatic backing 3, bonding Joining Technology is simple, and production cost is low.Through measuring, Composite filtering cloth with a thickness of 0.4~0.6mm, sheet resistance is about 2 × 109 ohm.
