Description
Technical field
The present invention relates to a kind of air-permeable layer, especially a kind of air-permeable layer on high-temperature powder conveying equipment, belongs to field of textiles.
Background technology
At present, the conveying of powder divides dry method and wet method two kinds.Wherein, dry method carries the preceence more and more showing it, and the air transportation trough in dry method conveying is the reliable apparatus supporting with powder conveying, compared with helical feed, the advantages such as it has that easy processing and manufacturing, cost are low, power saving, Maintenance and Repair work capacity are few, wherein air-permeable layer seems particularly important as the core component of air flume.
After the upper lower groove of air flume is separated by air-permeable layer, form upper groove body as material room, lower groove is as air chamber, take air as power, make to have the passing through micropores mistake of gas from air-permeable layer (fluid bed) of certain pressure flow, allow the material be fluidized change breath angle, make powder be " suspension " state.Air conveyer flume has constant slope, and after powder is fluidized suspension in air-permeable layer, its angle of repose reduces, and when being less than the leaning angle of skewed slot, by self gravitation and component effect, powder flow forward, reaches conveying object.The material of current China air-permeable layer has chemical fibre, pottery, carborundum etc., and to apply more be fiber product air-permeable layer.
The key technical indexes of the air-permeable layer of ceramic material is as shown in table 1.
The key technical indexes parameter of the ceramic air-permeable layer of table 1
The length of pottery air-permeable layer is generally 298,300,302mm, width is 150,151,155,300mm, thickness is 24,27,30,37mm.Shortcoming is there is: (1) ceramic air-permeable layer bursting strength is low by ceramic air-permeable layer known in table 1; (2) ceramic air-permeable layer is not more than 350mm × 300mm by manufactured materials restriction area, and thickness is not less than 24, is not suitable for supporting the use of large scale skewed slot; (3) ceramic air-permeable layer maintenance cost is high; (4) remaining normal uses required air pressure high, and use cost is high; (5) ceramic air-permeable layer seam leakproofness is poor, easily produces and leaks material and latch up phenomenon.
The main technical parameters of table 2 chemical fibre air-permeable layer
The main technical parameters of fiber product air-permeable layer is as shown in table 2, is the technical parameter of the air-permeable layer of the terylene material of PET5-6 in table 2 for model, wherein 5 numbers of plies representing fabric, the 6 thickness 6mm representing fabric.
There is technical disadvantages by chemical fibre air-permeable layer known in table 2: (1) chemical fibre air-permeable layer heat resistance difference is only 240 DEG C, be not suitable for hot environment and use; (2) chemical fibre air-permeable layer tensile strength is low.
So the at present conveying of high-temperature powder generally adopts is chain conveying, unavoidable selection for cement aluminium powder enterprise, chain-linked conveyer utilizes chain traction, carrying, or by the conveyer of the lath that chain is installed, metal mesh belt, roller-way equivalent-load material, its shortcoming mainly contain following some: (1) mechanism is complicated, accessory is more, and serviceability is poor; (2) carry phase specific energy consumption large with air; (3) fault rate is high, and accessory infringement frequency is high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of air-permeable layer on high-temperature powder conveying equipment is provided, the instantaneous heatproof of the air-permeable layer obtained reaches 550 DEG C, and operating temperature can reach more than 350 DEG C, makes air flume can be used for the conveying of high-temperature powder.
According to technical scheme provided by the invention, described air-permeable layer on high-temperature powder conveying equipment, feature is: described air-permeable layer adopts aramid fiber/copper wire yarn to be raw material, or adopts aramid yarn to be raw material, and weave on looms the air-permeable layer made and obtain plain weave multiple-structure.
Described air-permeable layer is the air-permeable layer of 3 ~ 6 layers of plain weave structure.
The aramid fiber of described aramid fiber/copper wire yarn employing 3 ~ 8 and the copper wire plying of 1 ~ 3 obtain.
The fineness of described copper wire is 0.1 ~ 0.25mm.
The twist of described aramid yarn is 11 ~ 16tex.
The fineness of described aramid yarn is 10 ~ 21s.
The every one deck of described air-permeable layer through close be 27 ~ 32/10cm, filling density is 27 ~ 32/10cm.
The present invention has following beneficial effect: the present invention is by changing the heat resistance of air-permeable layer, make its instantaneous heatproof reach 550 DEG C, operating temperature can reach more than 350 DEG C, improves the applicability of air-permeable layer, all can adopting of every high-temperature powder transportation art, and structure is simple, cheap, failure rate is low, good reliability, maintenance cost is low, has positive dissemination.
Accompanying drawing explanation
Fig. 1 is the technique line domain of the embodiment of the present invention one.
Fig. 2 is the technique line domain of the embodiment of the present invention two.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
The present invention utilizes aramid fiber and copper wire to replace Polyester Yarns in chemical fibre air-permeable layer as raw material, and combined high-strength fabric knitting technique, adopt the method for weaving of plain weave multilayer to weave the air-permeable layer of load-transfer device.And the air-permeable layer longitude and latitude line clear, the surfacing that weave, thickness is even, bursting strength is large, resistance is little, power consumption economize.According to user's requirement, air-permeable layer can be processed into different length and width sizes, and physical dimension is errorless, and without the need to splicing, good seal performance, does not leak powder during use.
Aramid fiber used in the present invention can adopt kevlar fiber, kevlar fiber (Kevlar) belongs to aromatic polyamide organic fiber, after glass fibre, carbon fiber, boron fiber, be used as fortifying fibre, first realize suitability for industrialized production by du pont company.This fiber bundle strength is 4 times of general organic fiber, and its modulus is 9 times of terylene.Because the proportion of kevlar fiber is little, so its strength-to-density ratio is higher than glass fibre, carbon fiber and boron fiber.But compression strength, shearing strength value are all lower, and hygroscopic character is higher, thus limit its application in some aspects.Kevlar fiber is mainly used to make rope, cable, japnning fabric, bullet-proof vest, and replaces glass fiber winding to make large-sized solid rocket chamber housing, also a large amount of as tire cord, can resistance to 150 DEG C ~ 160 DEG C high temperature.Another important application of kevlar fiber replaces carcinogenic asbestos, as the supporting material etc. of the brake facing of various drg, packing seal and clutch facing.
