Abstract
The utility model relates to composite filtering material for a filtering cylinder of a duster and is composed of a polymeric membrane and chemical fiber filtering material. The utility model is characterized in that the polymeric membrane is used as an outer layer; the chemical fiber filtering material is used as an inner layer; the outer layer and the inner layer are pressed through heat and compounded together; the polymeric membrane at the outer layer is a polytetrafluoroethylene millipore membrane; the chemical fiber filtering material at the inner layer is polyester fibre filtering material. The composite filtering material has the advantages of high strength, long service life, stable chemical properties, good moisture resistance, low cost, etc. The utility model can be used in wet conditions.
Description
The utility model is a kind of deduster filter cylinder composite filtering material, the filtrate class of solid dirt or flue dust in the big class of genus cleaning.
As everyone knows, filter cartridge dust remover is the dust removal by filtration equipment of being promoted in recent years of new generation.Because of its structure is light and handy, removing dust and clearing ash is that every profession and trade is selected conveniently.The filtrate of filter cartridge dust remover is traditional natural fiber, wood fibre.Natural fiber filtrate good hygroscopicity, but its easy and biological bacteria reaction, perishable, rotten, intensity difference the embrittlement phenomenon promptly occurs in temperature more than 100C °, and when the blowback of filter cylinder deashing, filtrate easily breaks, and service life is short, and the cost height increases the financial burden of enterprise.And natural fiber length thickness inequality causes the pore size filter skewness, influences filter efficiency.Wood fibre filtrate cost is low, but its intensity difference is not wear-resistant, and service life is short, easily chemically reactive.
The utility model discloses a kind of deduster filter cylinder composite filtering material, and it draws the advantage of above-mentioned two kinds of fiber filterings.This composite filtering material has chemical stability, and material is reclaimed Fails To Respond, and intensity is good, and is wear-resistant, and long service life is not softening under 130C ° temperature, even aperture distribution.
The utility model is achieved in that the outer polytetrafluoroethylmicroporous microporous membrane that is, internal layer is synthetic fibers or natural fiber.Fiber filtering carries out shredding earlier and is carded to fleece, and fiber is directed shop to be put, and it is quantitatively controlled.Under certain pressure and temperature it is reinforced, material forms the fiber filtering of hard.Polytetrafluoroethylene film is a kind of microporosity material through the special process expanding treatment, has hydrophobicity, resistant of high or low temperature, smooth surface, stable chemical performance.The hot pressing under the temperature of strictness, pressure, damp condition of fiber filtering and polytetrafluoroethylmicroporous microporous membrane is combined into composite filtering material.This kind composite filtering material chemical stability is good, the intensity height, and long service life, the surface is sliding, does not adhere to dust, and dust can not be penetrated into filtrate inside, realizes surface filtration, is easy to deashing.
With Figure of description the utility model is described below.
Accompanying drawing is the utility model structural representation.
With reference to the accompanying drawings, (1) is polytetrafluoroethylmicroporous microporous membrane among the figure, and (2) are synthetic fibers or natural fiber filtrate.Closely be combined into one through hot pressing.
Embodiment 1: fiber filtering (2) is made the utility model for a kind of polyester fiber filtrate.The composite filtering material of forming has intensity height, long service life, stable chemical performance, moisture-proof is good, cost is low, can be used for characteristics such as moist operating mode.
Embodiment 2: fiber filtering (2) is made the utility model for a kind of wood fibre filtrate.Long service life is also arranged, and smooth surface is easy to characteristics such as deashing.
The utlity model has smooth surface, adhere to dust, be easy to deashing, long service life, chemical property Stable, moisture-proof is good, cost is low, can be for characteristics such as moist operating modes.
Claims (5)
1. a deduster filter cylinder composite filtering material of being made up of film and fiber filtering is characterized in that macromolecule membrane (1) for outer, and synthetic fibers or natural fiber filtrate (2) are internal layer, and two layers through being combined into one.
2. deduster filter cylinder composite filtering material according to claim 1 is characterized in that outer macromolecule membrane (1) is a polytetrafluoroethylmicroporous microporous membrane.
