Description

Novel high speed spins porous superfine Denier fibre annealing device

Technical field:

The utility model belongs to chemical fibre and makes the field, and it relates to a kind of novel high speed and spins porous superfine Denier fibre annealing device.

Background technology:

Prior art as shown in Figure 1, when high speed spinning, below spinnerets 1, be equipped with the slow cooling pipe 2 that involutes by semicircle slow cooling pipe forward part 23 and semicircle slow cooling pipe rear section 24, slow cooling pipe 2 surfaces are the aperture 25 of distribution same diameter evenly, the tow 5 that the cooling blast 4 that is blown by quenching air window 3 enters in 25 pairs of circular slow cooling tube cavities 27 of aperture cools off, and has played the slow cooling effect.Because semicircle slow cooling pipe forward part 23 is often dismounting in process of production, cause semicircle slow cooling pipe forward part 23 easy deformation, so that be difficult for driving fit during with semicircle slow cooling pipe rear section 24 and cause that the slit is arranged with the hinge semicircle slow cooling pipe forward part 23 that links to each other in the daily production, easily produced to leak out since like this and make product quality decline.

In application number was 02219740.0 utility model patent, the designer once provided a kind of semicircle slow cooling pipe forward part 23 and semicircle slow cooling pipe rear section 24 on-deformable high-speed spinning porous superfine Denier fibre annealing devices of making.This device is that slow cooling pipe 2 is embedded on the multilayer laminar flow plate, can guarantee that slow cooling pipe 2 is not yielding after fixing, and the gap of leaving between semicircle slow cooling pipe forward part 23 and the slow cooling pipe rear section 24 is less, can improve the quality of product.But this utility model patent only can be applied to some existing high speed spinning window construction, and when being applied to other existing high speed spinning window constructions, product quality still can not improve.This thing happens often owing to the unequal institute of the spacing between the polylith spinnerets 1 of quenching air window 3 tops at this moment causes.In detail, for example: at spinning 0.3 dawn of single fiber, the hole count of spinnerets 1 is 144 orders, in one synnema of its ejection, when the monofilament radical is 144 a super fine denier long filament, every monofilament is to air-flow is very responsive on every side, if a monofilament is arranged when going out spinneret orifice in 144 monofilament, it is not smooth to flow, and in jet stretch process subsequently, the thinning process of this monofilament produces deviation with the thinning process of other monofilament on every side, this deviation makes follows air-flow generation disturbance around this monofilament, this flow perturbation is enough to influence the normal operation of other monofilament on every side of this monofilament, produces chain reaction, makes 144 monofilament fluctuations of service.Because of general quenching air window 3 tops 4～8 blocks of spinneretss 1 are installed again, when the spacing between the spinnerets 1 is also unequal, 4～8 beam combination silks of 4～8 spinnerets 1 belows are not the cooling blast 4 of complete uniform distribution from same quenching air window 3, but mobile being in " stable state " state of air-flow.If the chain reaction of the irregular operation of a monofilament can not be stopped in the above-mentioned spinnerets 1, it is easy to cause the former instability that has been in the cooling blast 4 of steady-flow of preceding 3 sides of quenching air window, thereby make tow 5 fluctuations of service of these quenching air window 3 the place aheads from 4～8 spinneretss 1, its consequence is that the dyeing of tow 5 produces the ingot potential difference, when serious, can not normally spin the super fine denier long filament.

Summary of the invention:

At above-mentioned defective, the utility model provides a kind of novel high speed to spin porous superfine Denier fibre annealing device to overcome its defective.

The technical scheme of the utility model technical solution problem is as follows:

A kind of novel high speed spins porous superfine Denier fibre slow cooling pipe unit, it comprises spinnerets, quenching air window, slow cooling pipe rear section, slow cooling pipe forward part, it is characterized in that described slow cooling pipe rear section and slow cooling pipe front portion are divided into asymmetric, both can form ellipse garden shape slow cooling tube cavity or circular slow cooling tube cavity, slow cooling pipe rear section is packed in quenching air window the place ahead, and lonely actinal surface links to each other by hinge with two ends, slow cooling pipe rear section outer arc actinal surface in the slow cooling pipe forward part two ends.

Described slow cooling pipe rear portion is divided into 2/3～7/8 of slow cooling pipe forward part.

Compared with prior art the utility model has the advantages that:

Because slow cooling pipe rear section of the present utility model and slow cooling pipe front portion are divided into asymmetric, and slow cooling pipe rear portion is divided into 2/3～7/8 of slow cooling pipe forward part, the air-flow that can enclose by the big radian bread of slow cooling pipe rear section like this in 4～8 slow cooling tube cavities that can make every quenching air window the place ahead is isolated each other fully, thereby can prevent the chain reaction that produced because of a monofilament irregular operation effectively, thereby reduced the dyeing ingot potential difference of porous super fine denier long filament significantly.Even do not close slow cooling pipe forward part simultaneously, the repiece success rate of its porous super fine denier long filament is also very high.The utility model is at the slow cooling pipe that can be higher than existing forward and backward two parts symmetry aspect the quality of row yielding and product significantly for this reason.
