Abstract
The utility model relates to a nitrogen-filled slow cooling device which is an assembly arranged under a spinneret in a terylene manufacturing industrial filament. The nitrogen-filled slow cooling device is wound with electric heating wires in the windward chamber composed of an inner cylinder whose wall is provided with small via holes and a coaxial outer cylinder, and the windward chamber is communicated with another ring-shaped clamping sleeve provided with a nitrogen air inlet pipe through a basic current regulator. The outer face of the slow cooling device is coated with heat-insulating material. The utility model can avoid the thermal oxidative degradation of the strand silk spun by a spinneret plate, increase the fibre strength and quality, ensure the cleanness of the surface of the spinneret plate, and prolong the using period of the spinning component.
Description
The utility model relates to the equipment of process industry with fiber, particularly delays the annealing device of strand cooling.
In the manufacture process of terylene industrial fiber,, below spinning head, be provided with the device that delays the strand cooling procedure, i.e. annealer for the good terylene industrial long filament of obtained performance.Its objective is that the strand that makes from the spinneret orifice ejection delays cooling velocity, reduce macromolecular preorientated degree, improve the drawing of fiber performance, thereby obtain high-intensity industrial fibre.Its formation is the heating wire that the metallic cylinder outer wall is wound with the covering and heat insulating layer, they can be with the air heat to 200 in the tube～300 ℃, by the strand of spinning head ejection in the metal cylinder by slowly being cooled off, its weak point is directly to contact with heated air from the strand that spinneret orifice sprays, the easy oxidized degraded of strand, spinneret face is easily stain simultaneously, influences spinning head life cycle and fiber quality.
In view of above-mentioned weak point the purpose of this utility model of the prior art is a kind ofly to be sprayed strand to overcome with nitrogen protection and produce the annealing device that thermal oxide is separated.
The purpose of this utility model can realize by following measure: fill the nitrogen annealer and be and make terylene industrial with a sub-assembly that is arranged in the long filament below the spinning head, it is characterized in that being provided with on by wall in the inner core of small through hole and the ipper air chamber that coaxial urceolus is formed and be wound with heating wire, ipper air chamber is that lower air chamber links by basic rectifier and another annular chuck that is provided with the nitrogen air inlet pipe.The annealer outside is coated with insulation material.
The utility model mainly is made up of lower air chamber, basic rectifier, ipper air chamber etc.It is the lower air chamber of annular chuck that nitrogen enters the bottom by air inlet pipe, is provided with basic rectifier above it.Because basic rectifier has certain damping action, makes nitrogen obtain uniform distribution along annular channel in lower air chamber, nitrogen enters basic rectifier rectification then.The just whole device in this basis is formed by accompanying rectification porous corrugated plating in the middle of one deck or the two-layer porous plate, it makes nitrogen flow along ipper air chamber's cylinder generatrix direction, and with the coupled ipper air chamber of laminar condition inflow, this ipper air chamber is provided with the inner core of small through hole and coaxial urceolus top is connected to form by wall, is wound with heating wire in it.The nitrogen that enters in this annular chamber constantly is heated as hot nitrogen by heating wire, and its these apertures by the inner cylinder wall enter in the cylindrical space that the annealer inner core wrapped up.And the annealer top joins with spinning head and inner chamber and spinnerets are corresponding.So the strand that sprays from spinnerets is surrounded by hot nitrogen fully, thereby obtained to avoid the slow cooling effect of thermal oxidative degradation.
Drawing is described as follows:
Fig. 1 is a cross-sectional schematic of the present utility model.
Fig. 2 is the local enlarged diagram of Fig. 1.
The utility model is described in further detail to utilize the example shown in the accompanying drawing.
Fill the cuing open in the schematic diagram of nitrogen annealer shown in Figure 1, ipper air chamber 4 is made of coaxial inner core 6 and urceolus 7 that the top links to each other, and both institute's clip spaces are cavity ringwise, is wound with the heating wire 5 that can link to each other with power supply on the inner tube wall in this chamber.On this inner tube wall, have many diameters and be not more than 3 millimeters small through hole.In basic rectifier partial schematic sectional view shown in Figure 2, basic rectifier 3 is stacked as one by annular porous plate 8 and annular porous corrugated plating 9 and constitutes, and its percent opening is not more than 60%.In Fig. 1, lower air chamber 1 cross section that is provided with nitrogen air inlet pipe 2 is the U font again, and the space that it comprised is annular cavity, and its width is identical with ipper air chamber.Ipper air chamber and lower air chamber combine by basic rectifier.Whole annealer outside is coated with insulation material.
The utility model has following advantage compared to existing technology:
1. the strand thermal oxidative degradation of spinneret ejection be can avoid, thereby fibre strength and quality improved.
2. can keep the spinning plate surface cleaning, prolong the filament spinning component life cycle.
