As shown in fig. 1 to 3, the present disclosure provides a type carbon drying apparatus including a cabinet 1 for accommodating type carbon, a heater 2 disposed in the cabinet 1, a control cabinet 3 disposed outside the cabinet 1 and electrically connected to the heater 2, and a gas circulation system communicating the inside and the outside of the cabinet 1; wherein, be provided with vent 11 on the box 1, heater 2 is used for drying type carbon, and switch board 3 is used for controlling the temperature of heater 2, and gas circulation system includes the intake pipe 4 that communicates with vent 11 and extend to in the box 1, set up in the box 1 outside and through draught fan 6 of 5 with box 1 interior intercommunication, heat exchanger 7 with draught fan 6 intercommunication and be used for the muffler 8 with heat exchanger 7 and box 1 intercommunication. Wherein, the heat exchanger 7 and the induced draft fan 6 can be communicated through a steam pipe 71. It should be noted that the size of the ventilation opening 11 is small, which does not have a great influence on the overall temperature inside the box 1, and the temperature inside the box 1 can be controlled by the control cabinet 3. The control cabinet 3 can be a PLC control cabinet provided with a temperature control program, and the temperature rise speed of the heater 2 in the box body 1 and the drying time at constant temperature can be controlled by detecting the temperature in the box body 1, so that the surface cracking damage of the molded carbon caused by rapid heating of the molded carbon can be avoided.

Through above-mentioned technical scheme, open draught fan 6 back, the air enters into in the intake pipe 4 through vent 11 to then in being inhaled induced duct 5 via box 1, then through heat exchanger 7 with the air heating, the air after the heating enters into inside box 1 through muffler 8, with this circulation of air in realizing box 1. Therefore, in the process of drying the molded carbon, the molded carbon can be prevented from being cracked and damaged in appearance due to rapid heating of the molded carbon, and combustion caused by overhigh local temperature of the molded carbon can be prevented, so that the yield of molded carbon production is improved.

In one embodiment of the present disclosure, the heat exchanger 7 may be a steam heat exchanger.
