The heat drafting device has the advantages that technical problems of pot boiling phenomena, easiness in yarn boiling phenomena and increase of broken yarns and residual yarns, roll winding phenomena in subsequent working procedures or deterioration of integral physical and mechanical properties of strands due to easiness in local overheating of the peripheries of existing heating pipes of existing heat drafting devices during heating can be solved; the heat drafting device can be used for carrying out heat drafting during carbon fiber precursor production.
Description
Technical field
The invention belongs to carbon fibre precursor field of textile equipment, and in particular to the hot gas spring in a kind of carbon fibre precursor production
Device.
Background technology
Drafting system be through carbon fibre precursor weave overall process a kind of indispensable equipment, its Main Function be
Under conditions of certain, external force is axially imposed in tow, the single fiber in tow is drawn and attenuated, improve the degree of orientation, have single fiber low
By force, the mecystasis that height is stretched is changed into high-strength, flatness elastic stage.
Existing hot gas spring device is susceptible to hot-spot around heating tube while being also easy to produce gas when heating using heating tube
Bubble, the disturbance of liquid medium and impacting to silk for generation bubble, easily produce the phenomenon of the residual silk of fracture of wire.
The content of the invention
The invention solves the problems that existing hot gas spring device easily produces the technical problem of the phenomenon of the residual silk of fracture of wire；And provide one
Plant the hot gas spring device in carbon fibre precursor production.
To solve above-mentioned technical problem, the hot gas spring device in a kind of carbon fibre precursor production of the present invention, including drawing-off
Roller 1, bath 3 and heating tube 4, the hot gas spring device also includes upper key drop 5, and the two ends near the inwall of bath 3 are arranged with
Two draw rolls 1, two bottom margin lines of draw roll 1 less than bath 3 upper surface, near the bottom land of bath 3 it is evenly distributed have plus
Heat pipe 4；The top of heating tube 4 is coated with key drop 5, and the upper key drop 5 is by the top board 51 being integrally connected and is symmetrical arranged
Swash plate 52 at the two ends of top board 51 constitutes (angle α between top board 51 and swash plate 52 more than 90 ° and less than 180 °), top board 51 with
Arc transition between swash plate 52, the top board 51 is in mesh, and the bottom of two swash plates 52 is fixedly connected with the bottom land of bath 3, institute
State top board 51 to be located between draw roll 1 and heating tube 4.
The upper key drop 5 is processed by corrosion-resistant material flitch, the preferably 304 corrosion resistant plates (work of radiating
With).
The hot gas spring process of the present invention：Tow 2 is moved into by the bottom of draw roll 1 for being arranged on the one end of bath 3, from being arranged on
The other end of bottom of draw roll 1 of bath 3 lays out, and tow 2 carries out hot gas spring by medium in bath 3.
The thickness of the corrosion-resistant material flitch is 2mm～5mm.The interior of bath 3 is fixed at the other two ends of the top board 51
On the wall of side, the disturbance of liquid and the area impacted to silk of generation bubble are reduced.
The distance between the bottom of the draw roll 1 and the top of heating tube 4 are 40～60mm；The top board 51 is located at draw roll
Centre position between 1 and heating tube 4.
Uniform manhole on mesh top board 51, manhole is arranged in arrays, aperture be 5mm～8mm, adjacent holes
Between centre-to-centre spacing be 20mm～25mm.
Using 304 stainless steel upper cover orifice plates 5, because stainless steel thermal conductivity factor is much larger than water, so when heating tube 4 transmits heat
When too high, heat can uniformly be spread out by upper key drop 5, so as to prevent the surrounding hot-spot of heating tube 4, it is to avoid
Boil silk boiling phenomenon so that medium temperature even, and then avoid phenomenon is damaged to tow 2, it is ensured that tow has
There is good overall physical and mechanical properties.
The present invention installs key drop 5 between heating tube 4 and walking tow 2, and the top board 51 of upper key drop 5 is in mesh
Shape, it is to avoid the disturbance of liquid medium and produce impacting to silk for bubble, so as to avoiding the generation of the residual silk phenomenon of fracture of wire.
The both sides of device top board 51 of the present invention arrange swash plate 52, and arc transition, prevent tow 2 sagging and heating tube 4 connects
Local Damaged is hindered in tactile generation, affects technological requirement.
Description of the drawings
Fig. 1 is the structural representation of the present invention, and Fig. 2 is the A-A sectional views of Fig. 1.
