Abstract
The invention discloses filter cloth and a filter bag for a suction vehicle and a double-pressure conveying vehicle and belongs to dust-removing filter cloth. The filter cloth is formed by weaving warp yarns (11) and weft yarns (12) in a double structure, wherein the weaving density of the warp yarns (11) and the weft yarns (12) is 60 to 350 yarns per 10 centimeters; the fiber structure of the warp yarns (11) is a basalt continuous fiber twisted yarn; and the fiber structure of the weft yarns (12) is matched with that of the warp yarns (11). The basalt fiber serves as a main material of the filter cloth, so that the cloth bag is prevented from being adhered to frameworks of the suction vehicle and the double-pressure conveying vehicle caused by high temperature during use. Compared with other fiber filter bags, the dust-removing filter bag of the suction vehicle and the double-pressure conveying vehicle, which is made of the basalt fiber, has the advantage that: the service life is prolonged by three times under the same condition. The filter cloth and the filter bag are simple in structure, suitable for industrialized production, high in batch production efficiency, low in production cost and easy to popularize.
Description
Technical field
The present invention relates to a kind of dust removal and filtration cloth, in particular, the present invention relates generally to a kind of filter cloth and filter bag for suction vehicle and two pressure conveying vehicles.
Background technology
Basalt continuous fiber material is described as " new material of 21 century ", to take basalt ore as raw material, to after ore reduction, add in smelting furnace, after 1450 ℃～1500 ℃ meltings, uniform fused mass is first pulled into crude fibre by bushing, and then crude fibre is drawn into the continuous fiber of all size by wire drawing machine, and adopt different sizes to infiltrate processing according to subsequent use, be processed to form final products.Due to the method water hardly, also almost without air pollution, itself is without chemical volatile matter, so the fiber preparation method of its a kind of environmental friendliness coordination.Due to preparation can be degradable basalt fibre filtering material in, not only protected environment, reduced the discharge of pollutant, take full advantage of widely distributed Minerals And Rocks, reduced widely production cost, so application prospect is very extensive.
Compare with other high-performance fibers such as glass fibre, carbon fiber, aramid fibers, basalt fibre not only mechanical property approaches carbon fiber, and has a lot of excellent functionality, as good in resistance to elevated temperatures, can continuous operation within the scope of-260～700 ℃; Acid-fast alkali-proof, anti-ultraviolet property is strong, and hygroscopicity is low, has better environmental resistance; Good insulation preformance, high temperature filtration is good, radioresistance etc.Therefore basalt fibre is considered to the low price substitute of carbon fiber, is the fourth-largest high-tech fiber after carbon fiber, aramid fiber, superhigh molecular weight polyethylene fibers.
The filter bag now often having has Glass Fibre Bag, pps Nomex dedusting filtering bag, terylene needled felt, polypropylene fibre Nomex, polyphenylene sulfide Nomex, aramid fiber Nomex, fragrant sulfone synthetic fibre Nomex, polytetrafluoroethylpunched punched felt, polyimides Nomex and high temperature composite series Nomex etc.And can at 200 ℃ of above fibers that use, only have P84, polytetrafluoroethylene (PTFE) (PTFE) and glass fibre, ceramic fibre, carbon fiber, high silica fiber and basalt fibre etc. for a long time.
Multi-functional pneumatic carries tank car also referred to as " two pressure conveying vehicle ", and two pressure conveying vehicles fully use strength to carry and the technology of isolated by filtration, has the multinomial advantages such as low, the advanced fluidization system of rational in infrastructure, efficient energy-saving, operation expense and environmental protection.Two pressure conveying vehicles are partly comprised of automobile chassis and upper dress, and upper dress part comprises rear tank body, material material feeding/discharge system and composition of the control system.
Pneumatic suction car is in conjunction with the principle that negative-pressure pneumatic is carried and positive-pressure pneumatic is carried, and integrates collection, conveying, Multi Loading and Unloading Functions, and the cleaning that completes various bulk cargos in sealing mode is collected and transportation.The effect of suction vehicle is the solid-state bulk cargo of suction or dust stratification, and material is entered and reclaims feed bin or appointed place.Its suction process, just as a large industrial dust collector, is utilized negative pressure to produce air stream and is carried suction and pumping material, by separation, dilatation sedimentation etc., material is stayed in major ingredient tank, and the Bas Discharged after filtration, guarantees that atmosphere is not contaminated.Discharge process is a malleation course of conveying, by compressed air, material in tank is discharged to specify and reclaims in feed bin.All the course of work is carried out under totally enclosed state, and do not run and emit, drop, be the necessary equipment of factory's cleaner production.
Suction vehicle and two pressure conveying vehicle are widely used in power plant, cement plant, steel plant and nonferrous metallurgy Absorption And Transportation dust, and their running environment is usually to move under hot conditions.Due to dust suction technique, the working of a furnace and absorb different its temperature that cause of factor such as flow and weather and fluctuate widely, filter bag is moved outward in design temperature scope, as steel mill, collect sintering dust temperature sometimes and can reach 600 ℃.Conventional high temperature filter bag is short service life at suction vehicle and two pressure conveying vehicle, and at high temperature easy and skeleton sticks together, and makes filter bag be difficult for changing, and increases repair time and human cost.
