Description

Apparatus and method for treating the return coal}

The present invention relates to an apparatus and a method for processing a return call generated in the process of flattening a call charged to a coke oven from a charging car in a coke plant. The present invention relates to a return call processing apparatus and a method for automatically processing a return call generated during a reciprocating movement of a beam through a smog sleeve without being separately processed at a separate place before the next flattening operation in a carbonization chamber.

As shown in FIG. 1, generally, the coke is produced by charging the call into the carbonization chamber 2 from the charging vehicle 1, and heating the charged call by operation of the combustion apparatus installation 2. As shown in FIG. On the other hand, the call charged in the carbonization chamber 2 constitutes a mountain-shaped charging state that forms a peak at the lower part of the charging hole 1a of the charging vehicle 1.

Therefore, in order to flatten the charging state of the call, the small door 4 located above the door of the carbonization chamber 2 is opened by using the open device 5a for the small door installed above the extruder 5, A smog sleeve 6 for guiding the discharge of dust or the like in the carbonization chamber 2 is pressed against the open portion of the small door 4. Thereafter, the leveler beam 7 mounted on the extruder 5 passes through the smog sleeve 6 into the carbonization chamber 2 and reciprocates to flatten the charging state of the call.

At this time, by the reciprocating movement of the leveler beam 7, the call, ie the return call, which is separated from the carbonization chamber 2 to the outside, is transferred through the smog sleeve 6 in the direction indicated by the arrow in FIG. 2 of the extruder 5. It is loaded in the return call hopper 10.

After performing the above-described flattening operation about 4 to 5 times, the extruder moving device is driven to the return call hopper for a long distance to process the return call loaded in the extruder return call hopper, and to perform the flattening operation in the carbonization chamber again. Place the extruder mover in the carbonization chamber.

However, the return call processing operation as described above is complicated and carries a risk of entanglement with field workers during long distance driving of the mobile device, and the return call loaded on the return call hopper is carried by the bucket to the 8th floor call bunker for processing. In the case of call-containing water, rainwater during rainy season, or siempic call, the call is stuck in the basket and return call hopper due to steam, which causes a lot of difficulties in return call handling and the risk of safety accidents when taking measures. There was this.

The present invention has been made to solve the conventional problems as described above, and collects the return call generated in the process of the flattening operation by the leveler beam during charging the coke oven in the lower part of the smog sleeve and It is an object of the present invention to provide a return call processing apparatus and a processing method capable of supplying and returning the collected return call to the carbonization chamber during the flattening operation in the next carbonization chamber without the long distance travel of the extruder mobile device.
