Abstract
The utility model discloses a cross air blasting device with an adjustable calm slow cooling region. The cross air blasting device comprises a cold air chamber, wherein the air outlet on the front wall of the cold air chamber is provided with a fixed baffle and a movable baffle, the fixed baffle is fixed at the upper part of the air outlet and is fixedly connected with the two side walls of the cold air chamber, the movable baffle is appressed to the fixed baffle, and the two ends of the movable baffle are arranged in sliding chutes extending forward on the two side walls of the cold air chamber. The cross air blasting device disclosed by the utility model is simple in structure, and influence to a cross air blasting flow is less, so that a fiber tow can obtain enough slow cooling time; and a calm slow cooling region is adjustable, so that cooling requirements of spinning technologies for different fibers can be met.
Description
Technical field
The utility model relates to a kind of cross air blowing device, particularly relates to the adjustable cross air blowing device in a kind of calm slow cooling district.
Background technology
In the preparation process of synthetic fiber, all adopt the melt spinning technology as fibers such as terylene, the silk that has just gone out spinnerets is in molten condition, must cool off, and fiber is changed into solid-state by molten condition.From present production technology, cooling device mainly contains two kinds, a kind of is cross air blowing device, another kind is the ring blowing device, no matter be which kind of blowing mode, these cooling devices are all undesirable to its cooling effect of fiber of the polyester formation of some modified poly esters or easily adhesion, its shortcoming is to cool off the easy embrittlement of fastfiber, impact is powerful, and the resolidified region of cooling off slow then fiber is long, easily produces adhesion, therefore in producing at present, usually in the spinnerets exit heater is set and carries out supplementary heating, zone of silence is set simultaneously controls cooling procedure, but because the zone of silence of present cross air blowing device all is a fixing zone, when therefore producing different kinds of fibers, need to change different cross air blowing devices and regulate cooling procedure, this has increased production cost undoubtedly, and apparatus adaptability is poor.
The utility model content
The purpose of this utility model provides a kind ofly can regulate arbitrarily the cross air blowing device of zone of silence size, is applied to the melt spinning production technology, and the control cooling velocity is to adapt to the technological requirement of different kinds of fibers.
The technical solution of the utility model is such: a kind ofly can regulate arbitrarily the cross air blowing device of zone of silence size, comprise the cold wind air compartment, it is characterized in that: described cold wind air compartment antetheca air outlet is provided with fixed dam and sideboard, described fixed dam is fixed on air outlet top, be fixedly connected with cold wind air compartment two side, described sideboard is close to the fixed dam setting, and the sideboard two ends are arranged on cold wind air compartment two side forward in the chute of extension.
In a specific embodiment of the present utility model, in order to obtain the even cooling air that gets, reduce the air turbulence that formed by the cross air blowing device structure influence, described fixed dam inboard is provided with constant-current stabilizer, and described constant-current stabilizer is at least one honeycombed screen plate.
Further, in order to reduce as far as possible impurity in the air, avoid uncured tow to be subject to impurity effect in the lateral blowing, described cold wind air compartment air inlet is provided with screen pack.
The advantage of technical scheme provided by the utility model is, reduced the air outlet area of cold wind air compartment by fixed dam, before fixed dam, form a fixing calm slow cooling district, by the sideboard before the slip fixed dam, change its upper-lower position, namely changed the air outlet area of cold wind air compartment, formed can adjusting size calm slow cooling district.This apparatus structure is simple, and offside blowing airflow influence is little, makes fibre bundle obtain the enough Slow cooling time, and calm slow cooling district can regulate the spinning technique cooling requirement that adapts to different kinds of fibers.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structure top view.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but not as to restriction of the present utility model.
See also Fig. 1 and Fig. 2, can regulate arbitrarily the cross air blowing device of zone of silence size, comprise cold wind air compartment 1, the left and right sides wall of cold wind air compartment 1 extends forward, forms the tow cooling zone.Spinnerets is installed in the upper end of cross air blowing device, and the fiber of molten condition becomes fibre bundle through the cooled region cooling curing after the spinneret orifice ejection of spinnerets.Cold wind air compartment 1 antetheca air outlet is provided with fixed dam 2 and sideboard 3, fixed dam 2 is fixed on air outlet top, be fixedly connected with cold wind air compartment 1 two side, fixed dam 2 inboards also are provided with a honeycombed screen plate 6, and cold wind air compartment air inlet arranges one deck screen pack 7.Cooling air filters through filter screen 7 and sends behind honeycombed screen plate 6 current stabilizations from air outlet, because stopping of fixed dam 2, namely formed a calm zone in fixed dam 2 the place aheads, fibre bundle is through this zone, cooling velocity is regional slow than air outlet, and therefore this calm zone is also referred to as the slow cooling district.The calm slow cooling district size that fixed dam 2 forms is changeless, in order to adapt to the spinning technique cooling requirement of different kinds of fibers, be close to fixed dam 2 and be provided with sideboard 3, sideboard 3 two ends are arranged on cold wind air compartment two side forward in the chute 5 of extension 4, the position of pressing close to cold wind air compartment two side on the sideboard 3 can arrange latch 8, put on lock bolt 9 in the latch 8, sideboard 3 be chute 5 interior can sliding up and down, and can fix its position after tightening lock bolt 9.This device changed the air outlet area of cold wind air compartment 1 by sliding up and down of sideboard 3, formed can adjusting size calm slow cooling district.
