Carbonizing device

Abstract

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.

1 . A carbonizing apparatus comprising: 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 chamber 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; 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, wherein the treatment object is carbonized while being sequentially passed through the preliminary chamber, the heating chamber, and the cooling chambers, and wherein the preliminary chamber is kept unheated. 
     
     
         2 . The carbonizing apparatus according to  claim 1 , wherein the transport means includes a container that receives the treatment object, and a conveyor that transports the container. 
     
     
         3 . A carbonizing apparatus that carbonizes a treatment object received in a container by passing the treatment object through at least a heating chamber. 
     
     
         4 . The carbonizing apparatus according to  claim 2 , wherein the container includes a box-shaped body formed by an open upper face, a bottom portion, and side wall portions provided on all sides, and a treatment-object set portion inclined with respect to the bottom portion such that the treatment object is set on the treatment-object set portion. 
     
     
         5 . The carbonizing apparatus according to  claim 4 , wherein one of a pair of faces of the side wall portions has a slot through which the treatment object is fed in the treatment-object set portion, and the other of the pair of faces of the side wall portions has a vent hole. 
     
     
         6 . The carbonizing apparatus according to  claim 5 , wherein a stepped portion that prevents the fed treatment object from falling off through the vent hole is provided between the vent hole and the treatment-object set portion. 
     
     
         7 . The carbonizing apparatus according to  claim 3 , wherein the container includes a box-shaped body formed by an open upper face, a bottom portion, and side wall portions provided on all sides, and a treatment-object set portion inclined with respect to the bottom portion such that the treatment object is set on the treatment-object set portion.
