There is a proposal such as No. 4 publication. However, each of these proposals is a method for preventing dust from the surface of the red hot coke loaded on the fire extinguisher in the wet fire extinguishing system.

[0006]

However, the dust generated before the coke discharged from the coke oven to the bucket truck is charged into the cooling tower is not limited to the dust generated from the surface of the coke, and the discharged coke is not the main body of the bucket. A small amount of dust is generated at the time of receiving the body, or when coke is put into the cooling tower from the bucket body, and the dust is accumulated around the bucket body and the bucket truck. Then, there is a problem that the accumulated dust is scattered in a strong wind and deteriorates the surrounding environment.

The present invention has been made in view of the conventional problems described above, and collects not only the dust from the surface of the coke loaded on the bucket truck but also the dust accumulated around the bucket body and the bucket truck. An object of the present invention is to provide a dust collector for bucket equipment in a coke oven that can generate dust.

Numeral 13 covers the bucket truck 3 together with the bucket body 4, and a hood truck running on a flat portion outside the rail 6 so as to move integrally with the bucket truck 3 which is pulled by the train 5 and moves on the rail 6. For example, the front and rear sides of the bucket truck 3 in the traveling direction and portions other than the bottom are surrounded by fixed hoods 13a, and the front and rear sides in the traveling direction are provided with, for example, shutter-type opening / closing doors 13b that can be automatically opened and closed as shown in FIG. . The shutter type opening / closing door 13b has a small installation area by adopting a simple mechanism of winding and rewinding the both ends of the shutter with a wire, for example, to install the dust collecting hood 14 described later. I try not to affect it.

Reference numeral 14 denotes a dust collecting hood 14 installed above the fixed hood 13a, which is connected to the wet dust collector 11a through a dust collecting duct 15. Further, the fixed hood 13a is provided with nozzles 16 inside both sides in the traveling direction of the hood truck, compressed air is supplied from the compressor 11b through a pipe 17, and accumulated around the bucket body 4 and the bucket truck 3. It is possible to inject compressed air to the dust.

By the way, as a means for moving the hood truck 13 integrally with the bucket truck 3, in the present embodiment, a means for connecting the hood truck 13 and the bucket truck 3 by a detachable connector 18 is disclosed. There is. For example, two couplers 18 are installed on both sides of the hood truck 13 and the bucket truck 3, for example, as a modification of the coupling equipment adopted in a general train car.

The dust truck 11 is pulled by the train 5 and runs. In addition, the traveling of the hood truck 13 in a state in which the bucket truck 3 is not connected is performed by
This is performed by the traveling mechanism 11c mounted on the No. 1 vehicle.

The dust collecting device of the bucket equipment in the coke oven of the present invention has the above-mentioned structure. Next, the dust collecting device having such a structure is used to remove dust accumulated around the bucket body 4 and the bucket truck 3. A method of collecting dust will be described.

First, when the coke discharged from the coke oven 1 is completely received by the bucket body 4, the opening / closing doors 13b before and after the traveling direction are opened to the right of the guide wheel 2 in FIG. The bucket truck 3 is pulled by the train 5 toward the hood truck 13 that is on standby. Then, as shown in FIG. 3, when the bucket truck 3 is housed in the fixed hood 13a of the hood truck 13, the train 5 is once stopped, and the bucket truck 3 and the hood truck 13 are stopped.
Are connected by the connector 18.

Then, after closing the opening / closing door 13b, the train 5 is run to pull the hood carriage 13 integrated with the bucket carriage 3 and the dust collection carriage 11 integrated with the hood carriage 13 to the cooling tower.

When the train 5 starts to run, the compressor 11b is driven to intermittently inject compressed air from the nozzle 16 installed in the fixed hood 13a to the periphery of the bucket body 4 and the bucket truck 3 to accumulate the air. Roll up the dust. The wet dust collector 11a is driven at the same time as the compressor 11b is driven, and the wound dust is passed through the dust hood 14 and the dust collecting duct 15 to the wet dust collector 11a.
To collect dust. During this dust collection, the open / close door 13b is closed before and after the fixed hood 13a in the traveling direction to maintain high airtightness, so that the dust that has been wound up does not scatter to the outside and can be efficiently collected.

The above-mentioned injection of compressed air and dust collection work are continued until the bucket truck 3 reaches the stop position just before the winding position of the bucket body 4 in the lower part of the cooling tower. Then, after the stop, the connector 18 is opened, the opening / closing door 13b is opened, and only the bucket truck 3 is pulled to the winding position while the hood truck 13 and the dust collecting truck 11 are left. Then, only the bucket body 4 is wound up along the cooling tower.

When the bucket main body 4 is wound up and reaches the upper part of the cooling tower, red hot coke is introduced into the cooling tower from the lower part thereof. Then, the bucket body 4 returns to the lower part of the cooling tower and is mounted on the bucket truck 3. Bucket trolley 3
Is towed to the standby position of the hood truck 13 and the dust collecting truck 11 with the open / close door 13b opened, and at the standby position, the hood truck 13 and the connector 18 are integrally connected again.
The open / close door 13b is closed.

After that, the hood truck 13 and the dust collecting truck 11 integrated with the bucket truck 3 are started to be pulled in the direction of the guide vehicle 2, and at the time of this pulling, dust collection similar to that described above is performed. At this time, the guide vehicle 2 has previously moved to the position of the furnace to be extruded next time (for example, 5 furnaces ahead of the previously extruded furnace), and the hood carriage 13 and the dust collection carriage 11 integrated with the bucket carriage 3 are After stopping once before the guide vehicle 2, the connector 18 and the opening / closing door 13b are opened.

Next, the bucket truck 3 is towed to the lower portion of the guide truck 2 and shifts to the preparation for receiving the coke pushed out next. The wet dust collector 11a supplies water at the standby position at the right end of the coke oven until the start of the next kiln removal. This water supply is performed by, for example, a pipe branched from a sprinkling pipe arranged in the periphery. In addition,
When collecting dust, the drainage is the drain pipe 11a below the wet dust collector 11a.
The water is discharged from a to a drainage groove 7 provided at the level of the rail 6, flows into the water collecting pit through the drainage groove 7, and is processed there.

[0024]

As described above, the dust collector for bucket equipment in the coke oven of the present invention covers the bucket body with the hood to prevent scattering of accumulated dust on the bucket body mounted on the bucket truck. And
Since dust is collected and removed by repeating dust collection while the bucket truck is being towed, most of the dust that accumulates on the lid of the dry fire extinguisher bucket body mounted on the bucket truck and its surrounding area is in the atmosphere. Dust can be effectively removed while preventing scattering inside.
