Abstract
The utility model discloses a vertical graphitizing furnace for carbon dust high temperature graphitization, which comprises a stainless steel furnace body, a graphite heating pipe, insulation material outside the graphite heating pipe, a feeding funnel, a discharging pipe, an argon inlet and a clean air outlet. The vertical graphitizing furnace for carbon dust high temperature graphitization is characterized in that an electromagnetic induction coil is arranged outside the insulation material, the electromagnetic induction coil is connected with an outer variable frequency induction power supply; the discharging pipe at the bottom of the furnace is connected with a feeding machine communicated with the discharging funnel. The utility model adopts the electromagnetic induction principle to heat, thus greatly reducing the energy, raising the temperature rapidly, and producing with high efficiency; and the time that the dust material passes through the graphite heating pipe can be controlled by adopting the feeding machine and controlling the moving speed of the dust material by the feeding machine.
Description
Technical field
The utility model relates to a kind of vertical high temperature graphitization stove.Especially relate to a kind of carbon dust high temperature graphitization that is used for, the high temperature graphitization stove of Graphite Powder 99 high temperature purification.
Background technology
With the carbon dust high temperature graphitization or with the Graphite Powder 99 high temperature purification mainly is to heat-treat at the high temperature of 2000-3000 degree by the high temperature graphitization stove to realize that its key equipment is the high temperature graphitization stove.The equipment of existing high temperature graphitization mainly is Acheson's type graphitizing furnace, and it is to fill the filler coke around carbide, and energising utilizes the resistance heating of coke indirectly, the graphitizing furnace that finally makes heating object itself also have a resistance and generate heat.Because Acheson's type graphitizing furnace will heat a large amount of filler coke, so the electric power unit consumption is many; And acheson furnace because of once the charging many, in the stove everywhere temperature differ bigger, make product quality stability poor.Every stove is from being warmed up to insulation, and the cycle that arrives cooling again is long, and it is low that efficient is prepared in production.Also have a kind of high temperature graphitization stove, be vertical graphitizing furnace, adopt step mode of operation.Can only disposablely put a furnace charge, every stove all passes through intensification at every turn, and the cooling blow-on is arrived in insulation again, and production efficiency is low, yields poorly, and the energy consumption height mainly only is appropriate to experimental production, is not suitable for the successive suitability for industrialized production.
The utility model content
It is low that the purpose of this utility model is to provide a kind of the purpose of this utility model to provide a kind of energy consumption, and the life-span is long, the high temperature graphitization stove that production efficiency is high.
The technical solution of the utility model is: comprise stainless steel body of heater, heating graphite pipe, outer lagging material, hopper, discharge nozzle, argon gas inlet mouth and the cleaning air outlet of heating graphite pipe; It is characterized in that be provided with electromagnetic induction coil in the lagging material outside, electromagnetic induction coil is connected with outside variable frequency induction power supply; Discharge nozzle at furnace bottom is connected with feeder, and feeder is communicated with discharge bucket.
Discharge nozzle outside in the body of heater bottom is provided with double-deck water(-cooling) jacket.
The utility model adopts electromagnetic induction principle to heat, and energy consumption is reduced greatly, and heat-up rate is fast, the production efficiency height; Adopt feeder feeding and the moving speed by feeder control powder, may command powder passing through the time in the heating graphite pipe.
Description of drawings
Accompanying drawing is the structural representation of the utility model one embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to accompanying drawing: present embodiment is provided with hopper 2, at the body of heater middle part heating graphite pipe 3 is housed on stainless steel body of heater 1, outside the heating graphite pipe, be provided with lagging material 4, be provided with electromagnetic induction coil 5 in the lagging material outside, electromagnetic induction coil 5 is connected with outside variable frequency induction power supply 6; Be provided with double-deck water(-cooling) jacket 8 in discharge nozzle 7 outsides, body of heater bottom.Discharge nozzle 7 is connected with feeder 9, and feeder 9 is communicated with discharge bucket 10.Be provided with argon gas inlet mouth 11 at discharge bucket 10 sidepieces, be provided with cleaning air outlet 12 in hopper 2 one sides.
During use, earlier with argon gas in argon gas inlet mouth 11 is sent into the heating graphite pipe, under argon gas atmosphere, send the higher frequency electromagnetic field by electromagnetic induction coil, produce eddy current at the graphite tube wall, eddy current makes the carbon tube heating, be warmed up to 2000-3000 ℃ rapidly, carbon dust or Graphite Powder 99 from top to bottom the process of flowing, are realized greying through 2000-3000 ℃ heating graphite pipe from the upper feed hopper of body of heater earlier, and other impurity in the Graphite Powder 99 will gasify and discharge through cleaning air outlet 12.The graphite powder cools off through the double-deck water(-cooling) jacket of discharge nozzle outside, and heat is taken away rapidly by water(-cooling) jacket, delivers to discharge bucket by feeder again.And the moving speed by feeder control powder, with control powder passing through the time in the heating graphite pipe.
Claims (2)
1. a vertical graphitizing furnace that is used for the carbon dust high temperature graphitization comprises stainless steel body of heater, heating graphite pipe, outer lagging material, hopper, discharge nozzle, argon gas inlet mouth and the cleaning air outlet of heating graphite pipe; It is characterized in that be provided with electromagnetic induction coil in the lagging material outside, electromagnetic induction coil is connected with outside variable frequency induction power supply; Discharge nozzle at furnace bottom is connected with feeder, and feeder is communicated with discharge bucket.
