Description
Technical field
The invention relates to a kind of high-strength high-modulus polyethylene fiber production field, particularly a kind of ring cold wind blower that is used on the spinning process.
Background technology
The high-strength high-modulus polyethylene production technology generally adopts the gel spinning method at present; The ultra-high molecular weight polyethylene spinning solution of fusion spins the back from the spinning pack of porous and directly cools off through air layer earlier; Get into freezing tank quenching gelation collagen silk then, as shown in Figure 1.There is following shortcoming in process of production in the method:
1, owing to have oxygen and all gases in the air, touch air from the high temperature spinning solution of spinning pack ejection after, the abrupt oxidization degraded immediately of gel fiber superficial layer, the strand xanthochromia, intensity reduces.
2, for anti-oxidation, the distance between spinning pack and the freezing tank try one's best near, be generally 2-3 centimetre; Cold air in the freezing tank rises, and causes the spinning pack surface layer temperatures to reduce, and the reduction of spray silk temperature causes the frozen glue filament surfaces coarse; Rough, can produce the head silk when serious.
3, because the distance between freezing tank and the spinning pack is too approaching; The air layer distance is too little; Before spin winding head tension force be transmitted to spinneret orifice; The spinning solution tension force time of unfolding causes the irregular phenomenon of fiber thickness serious inadequately, cause finally that high-strength high-modulus polyethylene fiber intensity is not high, lousiness increases, broken end increases, after spin the drawing-off instability.
For this reason, many manufacturers and knowledgeable people develop and develop to the defective of above-mentioned existence, but so far comparatively ideal solution are not arranged as yet.
Summary of the invention
In order to overcome existing above-mentioned deficiency in the existing spinning process, the purpose of the invention provides a kind of simple and reasonable, circulation rate is fast, cooling effectiveness is high, spinning quality is good high-strength high-modulus polyethylene fiber ring cold wind blower.
The invention solves this technical problem the technical scheme that is adopted; It comprises air accumulator, choke valve, the cooler that is used to store refrigerating gas; Described cooler comprises that the holder and the correspondence that are fixed on the spinning pack are fixed on inner barrel and the outer cylinder body on the holder, and inner barrel forms bundle channel, forms the unlimited annular of sealing end opening suitable for reading between inner barrel and the outer cylinder body and all presses the chamber; Annular all presses the end opening of chamber to be immersed in the cooling fluid of freezing tank; Be evenly equipped with some air admission holes that are used to cool off tow on the barrel of inner barrel, be provided with an air inlet on the outer cylinder body at least, be provided with an exhaust outlet on the inner barrel at least.
Be connected with air inlet pipe in turn between the air inlet of described air accumulator, choke valve and outer cylinder body, be connected with blast pipe on the gas outlet of inner barrel, be connected with rearmounted treating apparatus on the blast pipe.
Described refrigerating gas is nitrogen or inert gas.
After adopting said structure, following advantage and effect are relatively arranged with prior art:
The one, this device is installed after, gas cooled layer distance can be elongated greatly, the gas cooled layer can be adjusted to 5-30 centimetre.Little to spinning pack temperature effect, it is more abundant that the high temperature spinning solution is unfolded the disentanglement time, and the gel fiber structure that makes is more complete, and the surface is more smooth, and drawing-off lousiness broken end significantly reduces, but drawdown is splendid.
The 2nd, this device with nitrogen or inert gas as refrigerating gas; Circular flow under air-tight state; The non-oxidation degraded of gel fiber surface takes place, and spinning quality is stable, best in quality, can make the more more high-strength high-modulus polyethylene fiber of high-modulus of high strength; Improving more than 20% on the original basis, reach 40cn/dtex.
The 3rd, can be through the various parameters in the throttle valve adjustment cooler, cooling effectiveness is good, and the refrigerating gas of discharging from the inner barrel exhaust outlet can be recycled behind rearmounted treating apparatus, and operating cost is low.
