In above-mentioned open source literature, the shape of spinneret orifice and the structure of passage improve to some extent, the arrangement mode feature of spinneret orifice on spinnerets, the change of arrangement density, the structure of air deflector, the design feature of filter cloth are mentioned, to raising spray silk speed and spinning quality effect not obvious.
Summary of the invention
Goal of the invention: the present invention aims to provide a kind of spinneret cap of high speed dry spinning, solves the artificial fibres such as acetate fiber at the such as oblique silk carrying out there will be in high speed spinning process, solidifying silk and disconnected first order issue, to improve speed and the quality of spinning.
Technical scheme: the spinneret cap of a kind of high speed dry spinning disclosed by the invention, generally can be installed on the inlet device lower end of spinning solution, spray upper end, silk path, from top to bottom containing circular setting-up piece, multilayer filter cloth, air deflector, profile spinneret, the inlet device lower end of spinning solution, setting-up piece, multilayer filter cloth, air deflector, profile spinneret surround within it and fix by spinneret cap shell.
Profile spinneret has horizontal flanging, vertical flanging, spinnerets body, and spinnerets body has multiple spinneret orifice; Horizontal flanging is connected to the upper end of vertical flanging, and spinnerets body is connected to the lower end of vertical flanging, and the diameter of spinnerets body and the quantity of spinneret orifice can be greater than the diameter of traditional spinneret cap and the quantity of traditional spinneret orifice, and the quantity of spinneret orifice is 200-2000; The density of spinneret orifice near centre is greater than the density centre of the spinnerets body (or be solid section) of the spinneret orifice of surrounding.Due to the use of air deflector, can there is different changes in the pressure everywhere in spray silk liquid, and the corresponding different spray silk hydraulic coupling of different round platform drift angles and flow distribution, intermediate pressure and flow are greater than around.By the raising of middle spinneret orifice density, middle spray silk quantity is improved, also ensures that spray silk speed is everywhere substantially identical simultaneously.
The inner side of air deflector is in the Rotary-table side view of being inverted (meaning and upper bottom surface are greater than bottom surface), outside is for upper end is with the cylinder cylindrical shape (outside of meaning and air deflector is cylindrical cylindrical shape, and the upper end of air deflector is with the circular overlap of band) of the circular overlap of band.The height of air deflector is greater than the summation of this three of thickness of the thickness of multilayer filter cloth, the thickness of setting-up piece, the horizontal flanging of spinnerets, the width of circular overlap is substantially identical with the width of setting-up piece, the external diameter of cylinder cylindrical shape is slightly less than the vertical flanging internal diameter of spinnerets, and closely cooperates; The preferred 10-45 degree of angle of the round platform drift angle of Rotary-table shape (angle of the angle that the shaft section sideline of Rotary-table extends to form or shaft section both sides circular arc tangent line bottom), preferred 20-30 degree further, ensure that spray silk liquid has the effect of drawing pressurization in, with improve spray silk speed (angle too small, pressure effect is not obvious; Angle is excessive, and the descending resistance of spray silk liquid is also large, spray silk speed and uniformity not good enough).
The inner side of air deflector also can present the Rotary-table shape of inverted interior convex arc surface, and now the angle (round platform drift angle is now the angle of the shaft section both sides circular arc tangent line bottom of Rotary-table) of round platform drift angle is preferably 10-20 degree.
The bore suitable for reading of Rotary-table side view is greater than the bore in spray silk path, is less than or equal to the width of multilayer filter cloth; The end opening bore of Rotary-table side view equals or is slightly smaller than the bore in spray silk path.
In the present invention, multilayer filter cloth is preferably and is made up of the flannel fabric of one deck above and the high density nylon facing material of continuous three layers below, under ensureing that multilayer filter cloth has the prerequisite in better filter effect and service life, can tolerate larger spray silk hydraulic coupling.
Spinneret orifice on spinnerets body of the present invention can be distributed in 10-30 concentric ring circumferentially, the density of the spinneret orifice of the inside circle is greater than the density of the spinneret orifice of circle outside it successively; The angular compliance of the number of turns of concentric ring and the round platform drift angle of the different of deflector of conical shape, the number of turns of the less concentric ring of angle of round platform drift angle is more.
Beneficial effect:
The present invention is owing to increasing the diameter of spinnerets body, and the spinneret orifice density of mid portion improves, and this makes the quantity of spinneret orifice increase, thus the spinning output under same speed is also substantially increased.
Simultaneously, the design of deflector of conical shape makes the spray silk hydraulic coupling of spinneret cap inside become convergence from dispersion, pressure is larger and distribution is more uniform and stable, solve in conventional art due to spinneret cap diameter become large after in the spinneret cap that causes spinning pressure to diminish the problem of impact spray silk speed, make the speed of this dry spinning be increased to more than 700m/min, even can reach 750-950m/min.
And, adopt the cost of multilayer filter cloth lower, anti-extrusion, wear-resistant, the service life of the consumptive materials such as Lv Bu is longer.
The present invention is applicable to high-speed and high-efficiency dry spinning, while improve the stability of spinning process, the quality of spinning fibre is also more reliable and more stable, not easily there is oblique silk, solidifying silk, paste cap, disconnected first order issue in spinning process, can greatly improve spinning efficiency and yield rate, improve the economic benefit of manufacturing enterprise.
