CARBONIZING DEVICE

The carbonizing apparatus includes a heating chamber that thermally decomposes a treatment object by heating, a preliminary chamber through which the treatment object is carried from an outside into the heating member in a state in which the heating chamber is substantially shielded from the outside, the preliminary chamber being provided between the heating chamber and the outside, a plurality of cooling chambers in which the treatment object is treated after thermal decomposition, shielding doors that close the preliminary chamber, the heating chamber, and the cooling chambers arranged in series, a transport means that transports the treatment object while opening and closing the shielding doors, and exhaust pipes through which gas discharged from the preliminary chamber, the heating chamber, and the cooling chambers is exhausted. The treatment object is carbonized while being sequentially passed through the preliminary chamber, the heating chamber, and the cooling chambers.
