Abstract

The utility model relates to a gradient ring blowing rectifier for producing chemical fiber micro-fine denier filaments to cool and shape. Round and honeycomb-shaped holes are distributed on an internal and an external semi-cylinders or semi-elliptical cylinders, and horizontal flow guide and heat dissipation plates are spaced between the round holes and are arranged below a spinning box body. Hot filament bundles extruded from a filament jetting plate pass through a cylindrical or an elliptical cylindrical channel formed by combining the internal and the external semi-cylinders or semi-elliptical cylinders, and wind from a cooling wind source is forced to form a layer ring flow. The utility model simply solves the requirements of cooling and shaping micro-fine denier fibers, has the advantages of stable layer ring flow, low wind speed, fast heat dissipation, stable temperature gradient and no external interference, and is used for producing high-quality micro-fine denier fibers.

Description

Gradient rings is blown rectifier

The utility model relates to a kind of gradient rings that is used for cooling forming in the chemical fibre micro Denier silk of producing and blows rectifier.

At present, the cooling forming in the known production of chemical fibre has lateral blowing and ring blowing.Lateral blowing (Fig. 1): be semi open model, the laminar flow effect is relatively poor during less wind speed, and the wind speed shakiness is subject to external interference and forms turbulent flow.Ring blowing (Fig. 2,3): be semiclosed drum forms, the blowhole effective area is little, and the little heat radiation of heat exchange amount is slow during less wind speed.So used standard lateral blowing and ring blowing cooling forming mode all are not suitable for the micro Denier fiber of steady production high-quality.

The purpose of this utility model provides a kind of gradient rings and blows rectifier, can not only be used to produce high-quality routine, special fibre kind, can also be used for the micro Denier chemical fibre of steady production high-quality.

The purpose of this utility model is to realize like this, (long is 100-500mm at the rectangle metal sheet, wide be spinning jet used girth 0.55-0.7 doubly) go up opened round, honeycombed (horizontal stroke, the vertical setting of types row) eyelet, strike out semicolumn or semiellipse post (shape by used spray silk is fixed) then, at the circular eyelet interbody spacer flow-guiding radiation flat board of burn-oning, panel size is fixed by the size of device therefor and semicolumn or semiellipse post, according to the equipment situation, the semicolumn of several above-mentioned band flow-guiding radiation flat boards or semiellipse post are soldered to a determining deviation and have on semicircle or the half elliptic plate, make inside and outside each one group conjuncted, insert in below the manifold on the track, inside and outside group is conjuncted to be harmonious and to form the heated filament bundle that several cylinders or oval band of column bag are extruded from the box assembly spinnerets, wind from the cooling wind regime is forced to form stable layer circulation, the little rapid heat dissipation of wind speed, wind speed, the temperature of wind type and cooling forming part is not subjected to external interference, cool off uniform and stablely, and thermograde is stablized.

Owing to adopted such scheme, overcome the defective that existing standard lateral blowing and ring blowing cooling forming mode can not be used for steady production high-quality micro Denier fiber, extremely simply solved the specific (special) requirements of cooling forming in the micro Denier fiber production, be little wind speed of stabilized uniform layer circulation and rapid heat dissipation, thermograde is stable, is not subjected to external interference.

Below in conjunction with drawings and Examples the utility model is further specified.

Press Fig. 5, according to used spinning equipment, each spinnerets specification, quantity and spacing equidimension process gradient rings and blow rectifier.Sheet metal is with the thick duralumin of 0.5-1.0mm or rustproof aluminum alloy material, height 100-500mm, cylinder or cylindroid bundle channel by after turn forward 4 °～6 °.

In the embodiment shown in fig. 4, wind regime is existing side-blown wind regime, and this rectifier inserts in below the casing on the track, and group is conjuncted in inserting earlier, gives birth to good head back and fastens that to go up outer group conjuncted.

Claims

A kind of gradient rings is blown rectifier, it is characterized in that, for inside and outside two semicolumns or semiellipse post are distributed with circular and honeycombed eyelet on it, the horizontal flow-guiding radiation flat board of circular eyelet interbody spacer, inside and outside two semicolumns or semiellipse post interlock and form cylindrical or the elliptical cylinder-shape ramp way.
