Description
Technical field
The utility model relates to the carbon fiber production field, and particularly the continuous induction heating type fiber high temperature in the carbon fiber production process is handled stove.
Background technology
Carbon fibre composite is a kind of widely used new high-tech product.Carbon fiber is the most basic raw material of production and processing carbon fibre composite, and in the process of carbon fiber, high temperature cabonization technology and pyrographite metallization processes are one of important process procedures, and this technical process is finished by high temperature carbonization furnace and high temperature graphitization stove.
Present domestic high temperature carbonization furnace, its core component is a heater, the raw material of heater are the good graphite of conduction, specifically being shaped as graphite-pipe or forming middle by graphite cake is the rectangular configuration of cavity, two utmost points fixed installation metal electrode or transition at graphite heater are drawn, two electrodes carry out electrical heating by low-voltage and high-current, make the temperature in the heater cavity be controlled at 1000 ℃～1800 ℃, fibre bundle is generally the multiply synthetic fibre tows, in heater high temperature chamber, pass through by certain speed, tow is promptly by high temperature cabonization, tow is the carbon fiber finished product, direct drawing with graphite heater or transition of this kind structure electrode electrically contacts, and the mode of energising heating can be described as direct mode of heating or resistance heated mode.
As if the graphitization processing that the carbon fiber finished product behind the high temperature cabonization is passed through higher temperature again, promptly become the graphite fibre finished product, this technical process is similar to high temperature cabonization, and difference is that temperature is 1800 ℃ ~ 3000 ℃, if adopt direct mode of heating furnace construction to be difficult to bear this high temperature.
This structure is because heater or excessively to draw electro-temperature very high, and metal electrode must adopt water-cooling pattern, and the complicated heat loss of electrode structure is big.Key is that the conducting surface between metal electrode and the graphite cake is wanted the good quite difficulty that fits tightly.Because the bad mechanical strength of graphite piece can't be born bigger fastening force.Install for the normal temperature cold conditions in the installation process of equipment in addition, and belong to the operation of high temperature attitude in the course of the work, thermal stress changes greatly between electrode and the heater, and both faying faces change unavoidably, so the life-span of heater is short, are generally 200～400 days.Poor temperature uniformity, heat loss is bigger.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, the heater long working life, and temperature homogeneity is good, and fault rate is low, and heat loss is little, and continuous induction heating type fiber high temperature easy to maintenance is handled stove.
The technical solution of the utility model is: design a kind of continuous induction heating type fiber high temperature and handle stove, which comprises at least the heater that places the body of heater middle part, it is characterized in that: heater is the hollow cavity structure, heater is socketed in the inductor, heater does not contact with inductor, inductor two utmost point fixed metal electrodes.
Temperature in the described heater cavity is controlled at 900 ℃ ~ 3000 ℃.
Described heater is graphite or carbon carbon composite profiled member.
Described heater shape is that tubulose or centre are the rectangular configuration of cavity.
It is heat insulation to be filled with insulation material between described heater and the inductor.
Described inductor is a helical electromagnetic coils.
The beneficial effects of the utility model are: with the heater heating of directly switching on, change induction heating mode into or be the eddy current mode of heating.Generate an electromagnetic field by inductor, transmit energy in heater by the space, make heating element structure simplify greatly, exempted the labyrinth that draws the electricity part, the processed finished products rate of heater is improved, save baroque water cooled electrode by electromagnetic field; The heater long working life, generally at 500 to 1000 days even longer, because eddy-current heating is in certain space, the energy transmission is even relatively, makes the heater temperature homogeneity good, and the thermal stress of heater is improved, and makes it working life and increases; Heat loss is little, does not have water cooled electrode directly to be connected with the high temperature heater, has reduced the conduction loss of heat energy; Easy to maintenance, because simple in structure, the working life increase will inevitably reduce the workload of maintenance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the utility model inductor and heater part-structure schematic diagram.
Among the figure: 1, body of heater; 2, heater; 3, inductor; 4, electrode; 5, insulation material.
The specific embodiment
Shown in the structural representation that the continuous induction heating type fiber high temperature of the basis of Fig. 1 is handled stove, which comprises at least body of heater 1 and heater 2, heater 2 places body of heater 1 middle part, heater 2 is hollow cavity structures, heater 2 is socketed in the inductor 3, heater 2 does not contact with inductor 3, inductor 3 two utmost point fixed metal electrodes 4, inductor is a helical electromagnetic coils, the heater shape is a tubular structure, be filled with insulation material 5 between heater 2 and the inductor 3, any material that plays insulation effect all can be filled between heater 2 and the inductor 3, what present embodiment adopted is that the carbon felt and the heat insulation corundum matter that insulate meet insulation material, and the temperature in heater 2 cavitys is controlled at 900 ℃ ~ 3000 ℃, and this temperature range contains high temperature cabonization and high temperature graphitization technological temperature.
The concrete course of work is: be two metal electrodes, 4 energisings of helical electromagnetic coils with inductor 3, helical electromagnetic coils utilizes electromagnetic inductive heating principle that the heater 2 that is socketed in the inductor 3 is heated, fibre bundle passes through by certain speed in the high temperature chamber of heater 2, when the temperature in heater 2 cavitys is controlled between 900 ℃ ~ 1800 ℃, fibre bundle is the carbon fiber finished product promptly by high temperature cabonization; When the temperature in heater 2 cavitys is controlled between 1800 ℃ ~ 3000 ℃ promptly by high temperature graphitization, be the graphite fibre finished product, the drafting system of fibre bundle and specific embodiment and prior art are similar, do not describe in detail at this.
Owing to heating that heater is directly switched on, change induction heating mode into or be the eddy current mode of heating.Generate an electromagnetic field by inductor, transmit energy in heater by the space, make heating element structure simplify greatly, exempted the labyrinth that draws the electricity part, the processed finished products rate of heater is improved, save baroque water cooled electrode by electromagnetic field; The heater long working life, generally at 500 to 1000 days even longer, because eddy-current heating is in certain space, the energy transmission is even relatively, makes the heater temperature homogeneity good, and the thermal stress of heater is improved, and makes it working life and increases; Heat loss is little, does not have water cooled electrode directly to be connected with the high temperature heater, has reduced the conduction loss of heat energy; Easy to maintenance, because simple in structure, the working life increase will inevitably reduce the workload of maintenance.
