Description
Technical field
The present invention relates to a kind of spinning fiber-opening apparatus of producing in the carbon fibre precursor process, particularly a kind of air processor for carbon fibre precursor.
Background technology
In the spinning technique process of carbon fibre precursor, in order to realize PAN fiber high-strength, densification and thin dawn, tow after upper oil excessively is after compacting by drying is processed, also to carry out drawing-off for the second time, its objective is the drawing-off through 3～5 times, make tow adjust to last fiber number, and after drawn, yarn strength become higher.Tow in order to ensure superheated water drawing-off can also be stretched to this value, and having under hot environment that tow must provide at the full Heshui steam by middle pressure carried out, and needs to carry out steam drafting.The tow quantity of processing when steam drafting is more, and the stability of steam drafting is poorer.This is that the temperature difference from the centre to the edge increases due to the tow in the steam drafting pipe.When producing the following precursor of 6K, this temperature difference is also not fairly obvious, but, when producing the above precursor of 12K, the technology that reduces temperature difference must be applied to the steam drafting system.
Before steam drafting, the tow rear yarn that oils is coated by silicone oil, and silicone oil has some functional groups, the heat resinification of machine is dried when dry, silicone oil resin has high-adhesiveness, and makes contiguous silk bonding, thereby suppressed yarn, in the steam drafting pipeline, scatters.In order to reduce the temperature difference of the ducted tow of steam drafting from the centre to the edge, must cut off the bonding between silk, and then improve the spreadability of yarn.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of reasonable in design, for carbon fibre precursor, opens fine air processor.
Technical problem to be solved by this invention is to realize by following technical scheme, the present invention is a kind of air processor for carbon fibre precursor, be characterized in: comprise the processor between drawing roller up and down that is located at the steam drafting machine, processor is provided with the some supports that axially are arranged side by side along upper and lower drawing roller, the top of support is provided with the boundling godet roller, the bottom of support is provided with lower level and smooth godet roller, distance between upper boundling godet roller and lower level and smooth godet roller is 400-600mm, be provided with filament guiding seat on the support between upper boundling godet roller and lower level and smooth godet roller, filament guiding seat is provided with the through hole passed through for tow, be provided with along the through hole surrounding annular air runner that a circle and air inlet pipe are joined, the inwall of through hole is provided with 8-12 the fumarole be connected with the annular air runner, the center eccentric setting of the center line of fumarole and through hole, side-play amount is 2.5-5mm, compressed-air actuated air pressure by fumarole is 1.5-3kgf/cm
2, during air-treatment, yarn tension is 1.5-3 kg/cm
2, the air of fumarole ejection produces the air swirl that jeting area is annulus in through hole, makes operating tow monofilament separate and fully be unclamped.
Technical problem to be solved by this invention can also further realize by following technical scheme, and the diameter of described fumarole is 2-4mm, and the diameter of through hole is 25-50mm.
Technical problem to be solved by this invention can also further realize by following technical scheme, and the distance of described filament guiding seat and upper boundling godet roller is 150-250mm.
Compared with prior art, the present invention is by being provided with up and down processor at the steam drafting machine between drawing roller, while after the tow drying machine drying after oiling, entering processor, from the air blast of compressed air piping by the nozzle bore on processor, produce the air swirl that jeting area is annulus in through hole, make operating tow monofilament in through hole separate and fully be unclamped.Thereby the silk with the silk between oily bonding be cut open, and then thread spreading ability be improved.The yarn that enters jet chimney through air-treatment can promptly launch, and makes steam heat deliver to immediately the tow center.Facts have proved, can only drawing-off 1.8～2 times through steam drafting without the 12K precursor of air-treatment, and through the 12K precursor of air-treatment through 2.5～3 times of steam drafting energy drawing-offs, PAN precursor performance has obvious lifting.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the right TV structure schematic diagram of Fig. 1.
Fig. 3 is that the A of Fig. 1 is to structural representation.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
With reference to accompanying drawing 1 and Fig. 2, a kind of air processor for carbon fibre precursor, comprise the processor between the drawing roller up and down 2,6 that is located at the steam drafting machine, processor is provided with along upper and lower drawing-off roll shaft 2,6 to the some supports 4 that are arranged side by side, distance between adjacent two supports 4 equates with the spacing between the steam drafting pipeline, the top of support 4 is provided with boundling godet roller 3, the bottom of support 4 is provided with lower level and smooth godet roller 5, use lower level and smooth godet roller 5 can prevent that yarn 1 is staggered, improve the stability of steam drafting.Distance between upper boundling godet roller 3 and lower level and smooth godet roller 5 is 400-600mm.Distance is longer, and spreadability is better, yet, when distance surpasses more than 600 mm, will cause yarn 1 to be swiped by the nozzle inner ring surface and damaged, this situation about producing with too high air pressure is identical.
As shown in Figure 3, on the support 4 between upper boundling godet roller 3 and lower level and smooth godet roller 5, be provided with filament guiding seat 8, filament guiding seat 8 is provided with the through hole 9 passed through for tow, and the diameter of through hole 9 is 25-50mm.Filament guiding seat 8 should be placed on the position on the upper side of whole length, and described filament guiding seat 8 is 150-250mm with the distance of upper boundling godet roller 3.
Be provided with along through hole 9 surroundings the annular air runner 11 that a circle and air inlet pipe 7 are joined, the inwall of through hole 9 is provided with 8-12 the fumarole 10 be connected with annular air runner 11, the diameter of fumarole 10 is 2-4mm, the center eccentric setting of the center line of fumarole 10 and through hole 9, side-play amount a is 2.5-5mm.Air pressure is higher, and spreadability is better.Yet the too high meeting of air pressure destroys because the scraping of windage and nozzle inner ring surface makes yarn 1, causes the stability of steam drafting significantly to reduce, therefore the compressed-air actuated air pressure by fumarole 10 should be arranged on 1.5-3kgf/cm
2in scope.
At drying machine, last dryer roll and steam drafting enter yarn 1 tension force that degree of draft between material roller can be controlled air-treatment workshop section.Yarn 1 tension force is lower, and the monofilament motion is easier, and spreading property is improved.Yet too low tension force causes yarn 1 to enter the material roller place crooked and cause fluffing, this is due to due to the scraping of labyrinth entrance, so yarn 1 tension force should be arranged on 1.5～3kg/cm during air-treatment
2scope in.The air swirl that the air of fumarole 10 ejections is annulus at the interior generation jeting area of through hole 9, make the interior operating tow monofilament of through hole 9 separate and fully be unclamped.
The treated device of tow is sent in the steam drafting pipeline after processing.Because processed yarn 1 expands and untied fully, oily bonding between silk and silk is cut open and then the spreading ability of silk is enhanced, thereby reduced the temperature difference of the ducted tow of steam drafting from the centre to the edge, make the steam drafting multiple greatly improve, in order to realize PAN fiber high-strength, densification and thin dawn, created fine condition.
