Description
Technical field
This utility model belongs to spinning equipment field, particularly to being used for distributing the device of air-flow, steady wind pressure and uniform wind speed in a kind of synthetic fiber spinning machinery cold side blower system, in the spinning blowing apparatus producing coarse denier fiber.
Background technology
Along with the development trend of modern chemistry fiber, melt spinning industrial technology is just tending to two aspect development: one is that conventional variety scale is increasing, to high speed, high production capacity, high-efficient development；Two is that fibre in differentiation is more and more abundanter, has high intensity, fibre in differentiation multi-functional, high performance continues to bring out.Multi-functional, the exploitation of high-performance fibre in differentiation and development, rely primarily on the formulation of new technology and develop new product.New product development aspect mainly has fine denier filament, heavy denier yarn and shaped filaments, and wherein, coarse denier fiber refers to the filament number textile fabric at 5D-30D, requires higher cooling blowing condition: wind speed is high and wind speed is stable, and is uniformly distributed along fiber in production process.Because the melted cooling condition spinning heavy denier yarn, particularly important for controlling spinning quality, its intensity to fiber, elongation, yarn unevenness has conclusive impact.
Summary of the invention
For overcoming deficiency of the prior art, the purpose of this utility model is to provide that a kind of wind speed is higher, stationarity more preferable static pressure flow distributor.
This utility model be the technical scheme is that a kind of heavy denier yarn static pressure flow distributor, including front distribution plate, framework, rear distribution plate, it is provided with square tube flange between described front distribution plate and rear distribution plate, described framework is wrapped in described front distribution plate, on the frame of square tube flange and rear distribution plate, described front distribution plate, equal wind static pressure chamber is surrounded between square tube flange and rear distribution plate, described front distribution plate and rear distribution plate are made by the stainless sheet steel of punching, the percent opening of described front distribution plate is 8.97%-10.21%, the percent opening of described rear distribution plate is 7.42%-8.44%.
The further technical scheme of this utility model is: the described hole diameter on front distribution plate is 1.5-1.6mm, and pitch-row scope is 2.8-3.5mm.
Preferably, the described hole diameter on rear distribution plate is 1.5-1.6mm, and pitch-row scope is 2.6-4.5mm.
Preferably, 40mm it is spaced between described front distribution plate and rear distribution plate.
Preferably, this heavy denier yarn static pressure flow distributor also includes being attached on front side of described framework
Sealing gasket.
Principle of the present utility model is: when cooling wind from another wind chamber device after front distribution plate, air-flow quilt uniform distribution for the first time is in whole plate face, enter back into equal wind static pressure chamber, cooling wind is at this static pressure, obtain stable air-flow, distributed for the second time at distribution plate after air-flow arrival, owing to the percent opening of rear distribution plate is less than front distribution plate, therefore air-flow shrinks at each hole of rear distribution plate, so that the speed of per share air-flow increases, obtaining higher wind speed, more stable air-flow, wind speed is the highest can reach 0.5-0.8m/s.When spinning heavy denier yarn, spinning cold air blast velocity is higher than conventional spinning, and this static pressure flow distributor can meet cooling process conditions when spinning heavy denier yarn.
The beneficial effects of the utility model are: static pressure flow distributor air-out wind speed of the present utility model is uniform and stable, ensure that blowing balance when spinning cools down to a certain extent, improve spinning quality, be particularly suitable for spinning coarse denier fiber.

Detailed description of the invention
This utility model is described in detail below by the embodiment shown in below in conjunction with the accompanying drawings.
See shown in accompanying drawing 1,2, present embodiment discloses a kind of heavy denier yarn static pressure flow distributor, including sealing gasket 1, front distribution plate 2, framework 3, square tube flange 4, rear distribution plate 5.
The most front distribution plate 2 is 1mm-1.5mm steel plate processing and fabricating with rear distribution plate 5 with thickness, the punching of plate face has uniform aperture, aperture uniformly rule be covered with plate face, hole diameter is 1.5-1.6mm, pitch-row scope is 2.8-3.5mm, and percent opening (mark that space is shared in all materials is long-pending) is 8.97%-10.21%, after punching hole, smooth impulse-free robustness is answered in whole plate face, it is desirable to unevenness is less than 2mm/m.Rear distribution plate 5 uses thickness to be the processing of 1mm-1.5mm steel plate equally, and Ban Mianchong has uniform aperture, and hole diameter is 1.5-1.6mm, and pitch-row scope is 2.6-4.5mm, and percent opening is less than front distribution plate 2, and for 7.42%-8.44%, remaining requirement is identical with front distribution plate 2.
Square tube flange 4 uses the long 40mm in cross section, the rectangular square tube of wide 25mm to be welded, and square tube flange 4 includes four mutually perpendicular limits, and is respectively provided with fixed installation hole 6 on four limits.Equal wind static pressure chamber is surrounded between front distribution plate 2, square tube flange 4 and rear distribution plate 5.
Framework 3 makes of rustless steel thick for 2mm, front distribution plate 2 and rear distribution plate 5 are fixed on square tube flange 4 two sides front and back with rivet respectively, another with loading in framework 3, finally weld, the argon arc welding of four limits of framework is welded, wherein spot welding, other three limits firm welding, the acting as of framework 3 prevents side from having wind seepage, the most attractive in appearance.
When cooling wind from another wind chamber after front distribution plate 2, enter equal wind static pressure chamber, cooling wind, at equal wind static pressure intracavity static pressure, obtains stable air-flow；Air intake surface surrounding patch sealing gasket 1.
Melt spinning shaping is the heat transfer process of strand cooling and solidifying, needs cooling medium to cool down strand.In spinning produces, manufacturing technique requirent cooling system is provided that best molding condition, i.e. desirable to provide cooling condition can form ideal on spinning threadling and stable air-flow wind speed profile.In order to obtain structure and the uniform undrawn yarn of line density, to cooling condition and the flow regime of cooling medium, not only require stable in time, also require that the condition spatially formed between every synnema is essentially identical, be i.e. the stablizing of spinning process condition.The selection of spinning cooling condition and control are the important factor in order in as-spun fibre forming process, and it all has considerable influence to the degree of orientation of as-spun fibre, yarn unevenness, intensity etc..And this utility model is by arranging equal wind static pressure chamber, make air intake can air-out again after equal wind is stable, thus obtain stable air-flow, by front distribution plate and rear distribution plate are arranged rational percent opening, it is obtained in that and predetermined goes out wind velocity, meet the production of coarse denier fiber.
In sum; although this utility model discloses as above with preferred embodiments; so it is not limited to this utility model; artisan will appreciate that the change done in the case of without departing from this utility model scope and spirit disclosed in the claim appended by this utility model, all within protection domain of the present utility model.
