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 that is used for suction car and two force feed cars.
Background technology
The basalt continuous fiber material is described as " new material of 21 century "; Be to be raw material, with adding after the ore reduction in the smelting furnace, after 1450 ℃～1500 ℃ fusions with the basalt ore; Uniform fused mass is pulled into crude fibre earlier through bushing; And then crude fibre is drawn into the continuous fiber of all size by wire drawing machine, and adopt different sizes to soak into processing according to subsequent use, be processed to form final products.Because this method is water hardly, does not also almost have air pollution, no chemical volatile matter own, so the fiber production method of its a kind of environmental friendliness coordination.Owing in the basalt fibre filtering material that can degrade fully of preparation, not only protected environment, reduced the discharging of pollutant, made full use of the mineral rock widely that distributes, reduced production cost widely, so application prospect is very extensively.
Compare with other high-performance fibers such as glass fibre, carbon fiber, aramid fibers, basalt fibre not only mechanical property and has a lot of excellent functionality near carbon fiber, and is good like resistance to elevated temperatures, can continuous operation in-260～700 ℃ of scopes; Acid-fast alkali-proof, anti-ultraviolet property is strong, and hygroscopicity is low, and better environmental resistance is arranged; Good insulation preformance, high temperature filtration property 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 that now often has has Glass Fibre Bag, pps Nomex dedusting filter bag, terylene Nomex, polypropylene fibre Nomex, polyphenylene sulfide Nomex, aramid fiber Nomex, fragrant sulfone synthetic fibre Nomex, polytetrafluoroethylpunched punched felt, polyimides Nomex and the compound serial Nomex of high temperature etc.And can have only P84, polytetrafluoroethylene (PTFE) and glass fibre, ceramic fibre, carbon fiber, high silica fiber and basalt fibre etc. at the fiber that uses more than 200 ℃ for a long time.
Multi-functional strength transfer pot car is also referred to as " two force feed car ", and two force feed cars fully use strength to carry and the technology of isolated by filtration, has multinomial advantages such as low, advanced fluidization system of rational in infrastructure, efficient energy-saving, operation expense and environmental protection.Two force feed cars partly are made up of automobile chassis and last dress, and last dress part comprises the back tank body, and material material feeding/discharge system and control system form.
Strength suction car is to combine the principle that the negative pressure strength is carried and the malleation strength is carried, and collection collection, conveying, Multi Loading and Unloading Functions are one, accomplishes the cleaning of various bulk cargos with the sealing mode and collects and transportation.The effect of suction car is solid-state bulk cargo of suction or dust stratification, and material is entered recovery feed bin or appointed place.Its suction process is utilized negative pressure to produce air stream and is carried the suction and pumping material just as a big industrial dust collector, through separation, dilatation sedimentation etc. material is stayed in the major ingredient jar, and the air after the filtration is discharged, and guarantees that atmosphere is not contaminated.The discharge process is a malleation course of conveying, by compressed air material in the jar is discharged to specify and reclaims in the feed bin.All the course of work is carried out under totally enclosed state, and do not run and emit, drop, be the indispensable equipment of factory's cleaner production.
The suction car is widely used in power plant, cement plant, steel plant and nonferrous metallurgy with two force feed cars and absorbs the transportation dust, and their running environment usually is under hot conditions, to move.Because dust suction technology, the working of a furnace and absorb different its temperature that cause of factor such as flow and weather and fluctuate widely make filter bag outside the design temperature scope, move, and collect sintering dust temperature sometimes like steel mill and can reach 600 ℃.Conventional high temperature filter bag is short service life with two force feed cars at the suction car, and at high temperature sticks together with skeleton easily, makes that filter bag is difficult for changing, increase repair time and human cost.
Summary of the invention
One of the object of the invention is to solve above-mentioned deficiency, provides a kind of resistance to elevated temperatures good, and service life is than long a kind of filter cloth and filter bag that is used for suction car and two force feed cars.
For solving above-mentioned technical problem, the present invention adopts following technical scheme:
