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 production of carbon fibre precursor
Device.
Background technique
Drafting system be through carbon fibre precursor weaving overall process a kind of indispensable equipment, main function be
Under conditions of certain, external force is axially imposed in tow, the single fiber in tow is drawn and attenuated, the degree of orientation is improved, has single fiber low
By force, the high mecystasis stretched becomes high-strength, flatness elastic stage.
Existing hot gas spring device is easy to happen hot-spot around heating tube while being also easy to produce gas when being heated using heating tube
The phenomenon that bubble, the disturbance of liquid medium and generates bubble and causes to impact to silk, is easy to produce fracture of wire residual silk.
Summary of the invention
The technical issues of the phenomenon that being easy to produce fracture of wire residual silk the invention solves existing hot gas spring device；And provide one
Hot gas spring device in kind carbon fibre precursor production.
In order to solve the above technical problems, the hot gas spring device in a kind of carbon fibre precursor production of the invention, including drawing-off
Roller 1, bath 3 and heating tube 4, the hot gas spring device further include upper key drop 5, and the both ends close to 3 inner wall of bath are symmetrically arranged with
Two draw rolls 1, two 1 bottom edge lines of draw roll are lower than the upper surface of bath 3, close to 3 slot bottom of bath it is evenly distributed have plus
Heat pipe 4；It is covered with key drop 5 above heating tube 4, the upper key drop 5 is top plate 51 by being integrally connected and is symmetrical arranged
Inclined plate 52 at 51 both ends of top plate is constituted (angle α between top plate 51 and inclined plate 52 is greater than 90 ° and less than 180 °), top plate 51 with
Arc transition between inclined plate 52, the top plate 51 are in mesh, and the bottom of two inclined plates 52 is fixedly connected with the slot bottom of bath 3, institute
State the between draw roll 1 and heating tube 4 of top plate 51
The upper key drop 5 is process by corrosion-resistant material flitch, the preferably 304 stainless steel plates (work of heat dissipation
With).
Hot gas spring process of the invention: tow 2 is moved by 1 bottom end of draw roll that bath 3 one end is arranged in, and is existed from setting
Other end of 1 bottom end of draw roll of bath 3 is laid out, and tow 2 carries out hot gas spring by medium in bath 3.
The corrosion-resistant material flitch with a thickness of 2mm~5mm.The interior of bath 3 is fixed at the other both ends of the top plate 51
On side wall, reduces the disturbance of liquid and generate the area for causing impact to silk of bubble.
The distance between 4 top of 1 bottom of draw roll and heating tube is 40~60mm；The top plate 51 is located at draw roll
Middle position between 1 and heating tube 4.
Uniformly distributed circular through hole on mesh top plate 51, circular through hole is arranged in arrays, and aperture is 5mm~8mm, adjacent two hole
Between center away from for 20mm~25mm.
Using 304 stainless steel upper cover orifice plates 5, because stainless steel thermal coefficient is much larger than water, so when heating tube 4 transmits heat
When excessively high, heat can uniformly be spread out by upper key drop 5, to prevent 4 surrounding hot-spot of heating tube, be avoided
It boils silk boiling phenomenon, so that medium temperature even, and then avoid and phenomenon is damaged to tow 2, it ensure that tow has
There is good whole physical mechanical property.
The present invention installs key drop 5 between heating tube 4 and walking tow 2, and the top plate 51 of upper key drop 5 is in mesh
Shape avoids the disturbance of liquid medium and generates bubble and cause to impact to silk, so as to avoid the generation of the residual silk phenomenon of fracture of wire.
Inclined plate 52, and arc transition is arranged in 51 two sides of the device of the invention top plate, prevents tow 2 sagging and heating tube 4 connects
Touching, which generates, hurts Local Damaged, influences technique requirement.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention, and Fig. 2 is the A-A cross-sectional view of Fig. 1.
Specific embodiment
Specific embodiment 1: be illustrated in conjunction with Fig. 1 and 2, in present embodiment in a kind of carbon fibre precursor production
Hot gas spring device includes draw roll 1, bath 3 and heating tube 4, and the hot gas spring device further includes upper key drop 5, close to bath 3
The both ends of inner wall are symmetrically arranged with two draw rolls 1, and two 1 bottom edge lines of draw roll are lower than the upper surface of bath 3, close to bath
3 slot bottoms are evenly distributed heating tube 4；Key drop 5 is covered with above heating tube 4, the upper key drop 5 is by being integrally connected
Top plate 51 and the inclined plate 52 for being symmetricly set on 51 both ends of top plate are constituted, arc transition between top plate 51 and inclined plate 52, the top plate
51 other both ends are fixed on the inner sidewall of bath 3, and the top plate 51 is in mesh, bottom and the bath 3 of two inclined plates 52
Slot bottom is fixedly connected, and the top plate 51 is between draw roll 1 and heating tube 4；The upper key drop 5 be by with a thickness of
