Abstract
The utility model relates to a high temperature carbonizing furnace for producing carbon fibers, which is composed of a pulling roller (1), a sealing mouth (2), an outer casing (3), a graphite inner casing (9), a heat insulation layer (5), a temperature measuring viewing opening (14), and a heating element (8). The utility model is characterized in that a water jacket (4) is arranged between the outer casing (3) and the heat insulation layer (5); the outer casing (3) has a water feeding opening (6) and a water discharging opening (7); the heating element (8) is a Z-shaped graphite heating body fixed with the graphite inner casing (9); a graphite stop plate (10) is fixed with the graphite inner casing (9) between the graphite heating body (8) and a fiber passage (11). The utility model has the advantages of long service life, easy resistance regulation, easy temperature control, high furnace temperature, simple structure, easy fabrication, etc.
Description
The utility model belongs to a kind of carbide furnace, relates in particular to a kind of carbide furnace of producing carbon fiber.
The main raw material that is used to produce carbon fiber is polyacrylonitrile fibre (PANF), and PANF obtains carbon fiber through low temperature carbonization furnace and high temperature carbonization furnace carbonization treatment after pre-oxidation treatment.Present high temperature carbonization furnace mostly is horizontal, heater element is selenium carbon-point or carborundum, the power consumption of this selenium carbon-point and carborundum heater element is big, effectively burner hearth is little, is not suitable for large-scale industrial production, though and heater element to be the carbide furnace of graphite sheet overcome above-mentioned shortcoming, but there is cold and hot STRESS VARIATION big, life-span is short, and resistance is difficult for regulating the uppity shortcoming of temperature.
The utility model provides a kind of life-span long, the high temperature carbonization furnace of the production carbon fiber of easy temperature control system.
The purpose of this utility model is to realize like this, it is made up of drawing roller, sealed mouth, shell, graphite inner casing, heat-insulation layer, thermometric peep hole, heater element, it is characterized in that between shell and the heat-insulation layer cooling water jecket being installed, on shell, have water inlet and delivery port, described heater element is to be fixed in the graphite heater of the geometry of graphite inner casing for " it " font, and the graphite inner casing between graphite heater and fiber channel is fixed with the graphite plate washer.
Aforesaid heat-insulation layer is a carbon fiber felt.
The water leg that is provided with at the utility model guarantees that the graphite heater of " it " font and the contact-making surface of the input voltage utmost point superheating phenomenon do not take place and cause that current density increases." it " font graphite heater, cold and hot stress is little, and resistance is easily regulated, and can mate with input voltage, makes the easy temperature control system of carbide furnace, the furnace temperature height.Heat-insulation layer adopts carbon fiber felt, and density is little, resistance to elevated temperatures and good heat insulating in inert atmosphere.The graphite plate washer makes temperature equalization, and prevents the harm of lousiness to graphite heater.
The fiber dimensious of high temperature carbonization furnace feeding of the present utility model is 1K-320K, and feeding tow number is 100, and the speed of service is 70-120m/h.
The utlity model has following advantage:
(1) heating graphite element long service life, resistance is easily regulated.
(2) the easy temperature control system in the body of heater, the temperature height.
(3) simple in structure, easily processing.
Shell of the present utility model, water leg, sealed mouth can adopt stainless steel to manufacture.
Embodiment accompanying drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A face schematic diagram of the present utility model.
As shown in the figure, the 1st, drawing roller, the 2nd, be fixed in the sealed mouth on the shell 3, the 4th, the water leg between shell 3 and carbon fiber heat-insulation layer 5, the 6th, the coolant intake of on shell 3, opening, the 7th, the cooling delivery port of on shell 3, opening, the 8th, be fixed in " it " font graphite heater of graphite inner casing 9, the 10th, be fixed in the graphite plate washer of graphite inner casing 9, and be positioned between " it " font graphite heater 8 and the fiber channel 11, the 12nd, the sealed mouth that be fixed in shell 3 opposite sides corresponding with sealed mouth 2, the 13rd, the drawing roller that is positioned at shell 3 opposite sides of drawing roller 1 correspondence, the 14th, be positioned at the thermometric peep hole of high temperature carbonization furnace side.
When people use high temperature carbonization furnace to produce carbon fiber, connect power supply, make 8 heatings of " it " font graphite heater, make graphite inner casing 9 be warmed up to 1500 ℃, the low temperature carbon fiber is passed between drawing roller 1, in sealed mouth 2 enters graphite inner casing 9, come out from sealed mouth 12 and drawing roller 13 with the 80mm/h speed of service, promptly make carbon fiber.
Claims (1)
- A high temperature carbonization furnace of producing carbon fiber it be by drawing roller (1), sealed mouth (2), shell (3), graphite inner casing (9), heat-insulation layer (5), thermometric peep hole (14), heater element (8) is formed, it is characterized in that between shell (3) and the heat-insulation layer (5) water leg (4) being installed, on shell (3), have water inlet (6) and delivery port (7), described heater element (8) is to be fixed in the graphite heater of the geometry of graphite inner casing (9) for " it " font, and the graphite inner casing (9) between graphite heater (8) and fiber channel (11) is fixed with graphite plate washer (10).
