Description
Technical field
Field of chemical fiber production equipment of the present invention is related to a kind of dry heat draw box, and in particular to a kind of temperature high uniformity
Dry heat draw box.
Background technology
Since superhigh molecular weight polyethylene fibers have the characteristics that high intensity, high-modulus, low-density, with carbon fiber
Dimension, aramid fiber simultaneously claim the world today three big tec fibers.Since its molecular weight is high, main chain is combined, the degree of orientation, crystallinity
Height, thus its intensity be current all fibres most, (the 8 of high-quality steel wire are equivalent under the conditions of equivalent weight so that its intensity is high
Again), modulus is high (1300g/d), and great advantage is shown in advanced lightweight composite material, is widely used in national defence military supplies
Equipment, such as bullet-proof vest, the helmet and lightweight armor and civilian sail, hawser, parachute and filter material etc..
High-tenacity polyethylene fibre mostly uses super times of heat stretching process of gel spinning-and produces at present, the fiber through spinning moulding,
It is referred to as as-spun fibre.Since its structure is still unstable, supermolecule structure order is relatively low, so its Physical Mechanical can meet
A series of textile process requirement, it is necessary to which, by post-processing processes, most important one is exactly drafting process.After drawing-off is processed
After fiber obtains corresponding rock-steady structure, it can just meet the requirement of textile process, and have good stability in use, stretch
The macromolecular chain of fiber or aggregated structure unit are unfolded in the process, and along fiber axial direction oriented, in the same of orientation
When, along with the variation of phase and the variation of other structures feature.
The length of general draw box is 2.5 meters~6 meters, and using babinet self-circulation mode, hot wind one into one goes out, internal
There is thermostat.There is two-way, unidirectional hot wind circulation form.Temperature in general hot tank is inconsistent, uneven, but there are one bright
Aobvious temperature gradient drop.And this gradient drops, constant temperature heating device also is difficult to balance-its heat make-up, more forms air outlet
Hot blast temperature is high, and the low phenomenon of air inlet (circulating fan) temperature enters because of cold air in hot tank, can take away a part of heat
Amount, causes at the higher air outlet of temperature, and the stretching, extension of fiber is maximum, and plastic deformation is most apparent.Current draw box is generally deposited
In internal temperature, there are larger temperature differences, uneven to tow heating, reduce drawing effect, affect high-strength polyethylene fibre
Dimension, the quality of carbon fiber and aramid fiber product.
Invention content
A kind of dry heat draw box of temperature high uniformity is provided the invention aims to overcome the deficiencies in the prior art.
In order to achieve the above objectives, the technical solution adopted by the present invention is：A kind of dry heat draw box of temperature high uniformity, it
Including babinet, can be opened and closed mounted on the top of the box cover board, be fixed on the bottom of box multiple supporting legs, be mounted on
Air duct mechanism in the babinet, be mounted in the middle part of the babinet and with the air duct mechanism matched hot body, setting
In the hot body both sides and be connected with air duct mechanism end pressure stabilizing mechanism, be mounted on the pressure stabilizing mechanism and institute
It states the outlet air regulating valve between babinet and is inserted on the cover board and extends to the temperature detecting resistance in the babinet.
Optimally, the air duct mechanism, which includes both ends, has the ventilation slot of arcwall face, is opened in the ventilation slot upper surface
Both ends and air outlet corresponding with the arcwall face and in the ventilation slot and symmetrical about the hot body
Multiple even air holes plates.
Further, the hot body include be mounted on circulating fan in the middle part of the air duct mechanism, be mounted on it is described
The bottom of box and be connected with the circulating fan motor, cover on the circulating fan hot wind mixing cover and installation
The more heating rods in hot wind mixing cover.
Further, there are two the pressure stabilizing mechanisms, they be mounted on the air duct mechanism top and respectively with it is described
Air outlet is connected；The outlet air regulating valve is fixed on the top of the air outlet.
Further, the pressure stabilizing mechanism includes the first surge-chamber, the second surge-chamber and third surge-chamber being sequentially communicated,
Opening is offered at the top of first surge-chamber, the second surge-chamber and third surge-chamber.
Since above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：Temperature height of the present invention
Uniform dry heat draw box is coordinated by using air duct mechanism, hot body, pressure stabilizing mechanism etc., and by hot body
In the middle part of the babinet, the stroke of hot air circulation process can be reduced in this way, avoiding it, temperature is not caused by heat loss
So that the temperature difference of final dry heat draw box in the horizontal direction is ± 1 DEG C, and temperature difference in the vertical direction is ± 0.5
℃。
