One end is connected through outer framework 304 with the charging aperture of coke discharging tank 600.
Coke discharging tank 600 can be made as double-decker using stainless steel, to improve its intensity.Further, coke discharging tank 600
Designed using two-part Split type structure up and down, so as to being cleaned inside coke discharging tank 600.In order that tar steam can be suitable
Sharply by entering coke discharging tank 600 in body of heater 302, the coke discharging hole in the vertical direction that can make to be arranged on body of heater 302 is more than
The charging aperture of coke discharging tube is in the height of vertical direction, and the coke discharging connecting tube 601 for connecting body of heater 302 and coke discharging tank 600 has
One inclined plane 602.
Height with respect to the horizontal plane of the inclined plane 602 of connecting pipe adjacent to the side in coke discharging hole is more than inclined plane 602
The height with respect to the horizontal plane of the neighbouring side of coke discharging tank 600.Using the coke discharging connecting tube 601 with inclined plane 602 so that burnt
Oil can more swimmingly enter coke discharging tank 600, reduce the situation that tar passes back into body of heater 302 that occurs.Coke discharging tank 600 can both couple cold
Condensate, vapours or hot water can be also connected, in order to the collection or discharge of tar.
Furthermore it is also possible to heating tape is connected in the above-mentioned connecting tube with inclined plane 602, to avoid coke discharging connecting tube
601 block.In order to facilitate changing and cleaning coke discharging tank 600, coke discharging tank 600 can be connected using fast acting flange with body of heater 302.
When needing to change coke discharging tank 600, flange is dismantled, coke discharging tank 600 is removed, while close coke discharging hole, prevent gas in body of heater 302
Body leaks and keeps ambient atmos environment to isolate with gaseous environment in body of heater 302.Can be by body of heater 302 by discharging device for coke 603
Interior tar steam is extracted out, the then cooling storage in coke discharging tank 600, the environment in body of heater 302 is kept relative cleaning, with
Beneficial to the production of Carbon fibe.
Caused coal tar is occurred tar steam and is attached to the interior of body of heater 302 by thermal evaporation in the production process of Carbon fibe
The problem of roof.In the present embodiment, the situation of furnace roof is attached to for tar steam, Carbon fibe continuous production retort 200 is set
The part in coke discharging hole is equipped with, the top of body of heater 302 is arranged to vault construction.
The design of vault construction, the inner roof wall for making body of heater 302 is arcuate structure, so as to improve tar steam in body of heater
The attachment difficulty of 302 inner roof wall so that tar steam is not easy the inner roof wall condensation in body of heater 302.Therefore, using vault construction
Design, the top of body of heater 302 is more easily kept cleaning, and vault construction builds that more convenient, firmness is higher by laying bricks or stones.
The problem of for producing waste gas in Carbon fibe production process, the body of heater 302 of Carbon fibe continuous production retort 200 is also
Waste gas outlet is provided with, Waste gas outlet connects with furnace chamber 305.Waste gas outlet can pass through pipeline, valve and the external world
Air-extractor such as air pump connects, to discharge the waste gas in the furnace chamber 305 of body of heater 302 when necessary.
Refering to Fig. 4, the heating component 306 in the present embodiment includes multiple heaters.Multiple heaters are respectively positioned at multiple
The both sides up and down of driving member 103.Due to transporting in driving member 103 more specifically in roller rod for Carbon fibe raw material and product
204 centre transports portion 201, therefore, is heated from the both direction up and down of driving member 103, can make Carbon fibe raw material by
Heat is more uniform, is advantageous to improve the quality of product.The selection of heater has a variety of, and heater 404 is used in the present embodiment.Tool
Body, refering to Fig. 8, heater 404 includes inner side ceramic rod 405, resistance wire 407 and outside ceramic jacket 406.Outside ceramic jacket
406 are provided with accommodating cavity, and 405 sets of inner side ceramic rod is arranged in accommodating cavity, and resistance wire 407 is located in accommodating cavity and is set around interior
Side ceramic rod 405.
The inner side ceramic rod 405 and outside ceramic jacket 406 formed using ceramic material has higher heat resistance,
Be not susceptible to deformation, and it is anticorrosive, heat transfer efficiency is high.Using inside and outside ceramic structure Seal resistances silk 407, resistance wire can be avoided
407 are corroded, and improve the service life and heat utilization rate of resistance wire 407.
In order to improve uniformity of the heater 404 to the heat effect of air in body of heater 302, resistance wire 407 is made pottery in inner side
Winding method on porcelain rod 405 is preferably：Coiling density of the resistance wire 407 adjacent to the part of the madial wall of body of heater 302 is more than electricity
Coiling density of the silk 407 away from the madial wall of body of heater 302 is hindered, i.e. resistance wire 407 takes the mode winding that both sides are close, centre is loose
In inner side ceramic rod 405, to cause the temperature of each position in stove more uniform.
Referring to Fig. 4 and Fig. 7, Carbon fibe continuous production retort 200 is additionally provided with gas inlet pipe 301, gas
The tube wall of input pipe 301 sets multiple input pipe stomatas, and input pipe stomata is located in body of heater, and connected with furnace chamber 305.Utilize
301 extraneous feeder of gas inlet pipe can be passed through gas into furnace chamber 305, to increase the air in furnace chamber 305
Disturbance, make the temperature in furnace chamber 305 more uniform.On the other hand, can by continuing to input gas into furnace chamber 305
Make the air atmosphere that pressure-fired is kept in furnace chamber 305, so as to avoid the situation that ambient atmos mix into furnace chamber 305.
Secondly, the tube chamber of gas inlet pipe 301 can also connect with the tube chamber of seal air pipe 101.Due to gas inlet pipe
301 tube chamber connects with the tube chamber of seal air pipe 101, so as to utilize the gas injection into gas cavity of gas inlet pipe 301, then
Via the gas injection into the tube chamber of seal air pipe 101 of steam vent 105, the laying of the interior conduit of furnace chamber 305 can be thus reduced,
Simplify the structure of body of heater 302.
Because high temperature Carbon fibe has higher reactivity, easily with the oxygen reaction in air, therefore, by Carbon fibe
Before output, it is cooled down, the quality of Carbon fibe can be effectively improved, and can reduce Carbon fibe transports direction
On body of heater 302 size, so as to reduce fiber continuous production retort difficulty of construction and construction cost.
