Abstract

The utility model discloses a refuse grease proofing needled filter felt of water, paste the composite fiber layer on surface about the base cloth and locate the surperficial PTFE fiber layer of composite fiber layer including base cloth, symmetry, the base cloth is interweaved by warp and woof and forms, warp and woof all include dacron yarn and electrically conductive yarn, 10~12mm of the dacron yarn every electrically conductive yarn of arranging, composite fiber layer is glass fiber and P84 fibre composite fiber layer. The utility model discloses have good chemical property, good filtration efficiency, good gas permeability, tensile strength is high, and the elongation is good, has water and oil proofing and lasting anti -static function.

Description

One is refused the grease proofing needled filtering felt of water

Technical field

The utility model relates to filter felt, is specifically related to one and refuses the grease proofing needled filtering felt of water.

Background technology

Needled filtering felt series filtrate adopts nonwoven needled technique, and makes through thermal finalization and other processing methods, is widely used in industry and catches dirt, the aspects such as smoke and dust treatment; Utilize existing needled filtering felt to process water capacity greatly or the larger dusty gas of viscosity, the easy attached cloth bag of dust, causes the service life of needled filtering felt, cleaning cycle greatly to shorten.

Summary of the invention

Goal of the invention: for the deficiencies in the prior art, the utility model provides one to refuse the grease proofing needled filtering felt of water, has waterproof and oilproof and lasting antistatic property, has extended service life and cleaning cycle.

Technical scheme: the grease proofing needled filtering felt of water of refusing described in the utility model, comprises that base cloth, symmetry stick on the composite fibre layer of base cloth upper and lower surface and be located at the PTFE fibrage on composite fibre layer surface; Described base cloth is interwoven by warp thread and weft yarn, and described warp thread and weft yarn include Polyester Yarns and conductive yam, Polyester Yarns every 10 ~ 12mm conductive yam of arranging, and described composite fibre layer is glass fibre and P84 fiber composite fibrage. PTFE fibrage has the good waterproof performance of draining the oil, P84 fiber has stronger resistance dirt and catches dirt ability, can improve filter efficiency, simultaneously naturally curling, between fiber, there is stronger cohesive force, strengthen with glass fibre adhesion, the anti-wear performance of needled filtering felt, peel strength are obviously improved.

Further improve technique scheme, described conductive yam is formed by the blending of evenly arranging of stainless steel fibre and cotton fiber. The conductive yam that adopts blending to form has higher electric conductivity, can not gather static, thereby make corresponding needled filtering felt have anlistatig function during by application.

Further, the outer surface of described stainless steel short fiber is provided with conductive black. The roughness that conductive black can increase stainless steel short fiber outer surface strengthens the cohesive force of stainless steel short fiber and cotton fiber in conductive yam, has improved the tensile strength of conductive yarn.

Further, the thickness of described Nomex is 1.5 ~ 3.5mm. Air penetrability, filtration resistance, filter efficiency, the production cost of thickness on needled filtering felt has very important impact, 1.5 ~ 3.5mm is set and can on performance and cost, accomplishes relative equilibrium.

Further, described warp thread comprises that Polyester Yarns and conductive yam, Polyester Yarns are every the 11mm conductive yam of arranging, and described weft yarn comprises that Polyester Yarns and conductive yam, Polyester Yarns are every the 11mm conductive yam of arranging.

Beneficial effect: compared with prior art, advantage of the present utility model: the utlity model has good chemical property, good filter efficiency, good gas permeability, tensile strength is high, and percentage elongation is good, has waterproof and oilproof and lasting antistatic property, can be applied in the occasion that water capacity is larger, compared with common filter felt, filtrate is difficult for stopping up sticks with paste bag, has significantly improved service life and cleaning cycle, the gas flow passing through also strengthens, and saves energy consumption and reduces maintenance cost.

Detailed description of the invention

Below by accompanying drawing, technical solutions of the utility model are elaborated.

Embodiment 1:As shown in Figure 1 and Figure 2 refuse the grease proofing needled filtering felt of water, comprise that base cloth 1, symmetry stick on the composite fibre layer 2 of base cloth upper and lower surface and be located at the PTFE fibrage 3 on composite fibre layer surface; Base cloth 1 is interwoven by warp thread and weft yarn, warp thread comprises that Polyester Yarns 12 and conductive yam 11, Polyester Yarns 12 are every the 11mm conductive yam 11 of arranging, weft yarn comprises that Polyester Yarns 12 and conductive yam 11, Polyester Yarns 12 are every the 11mm conductive yam 11 of arranging, conductive yam 11 is by the blending of evenly arranging of stainless steel fibre and cotton fiber, and the outer surface of stainless steel short fiber is provided with conductive black; Composite fibre layer is glass fibre and P84 fiber composite fibrage.

As mentioned above, although represented and explained the utility model with reference to specific preferred embodiment, it shall not be construed as the restriction to the utility model self. Not departing under the spirit and scope prerequisite of the present utility model of claims definition, can make in the form and details various variations to it.
