Description

[Detailed Description of the Invention] The movement of the equipment toward the coke oven and the movement of the charging coal leveling device toward the coke oven are performed independently, and the preliminary work of coke pitting is performed without being constrained by the coal charging and leveling work. The present invention relates to a coke oven operating method and apparatus thereof, and is intended to improve the efficiency and productivity of coke oven unloading and coal charging operations in a coke oven.

In the conventional coke extruder, the coke extrusion device and the charged coal leveling device were installed side by side, so after the extruder finished coke extrusion work at the designated temple, the coal was charged into the same kiln by the coal charging car. It is necessary to level the charged coal at regular intervals, and since the above-mentioned charging vehicle only has coal charging equipment for one cave, the coal is leveled every time one cave is finished charging. It is necessary to drive to the tower and supply charging coal,
It takes time to travel, and the closed packet truck or fire extinguishing truck that stores the extruded coke is one cave's worth of push 11j.
Since it only has a coke storage capacity, it is necessary to transport extruded coke from the cave to a dry or wet cooling device each time it is stored, which takes time and reduces wasted time when moving to the next operation. There were deficiencies that made it difficult to measure improvements in work efficiency and productivity.

The present invention has been made in view of the above-mentioned defects, and an embodiment of the present invention shown in the drawings will be described.
No-ll! The coke pusher 3 and the charged coal leveling wheel 11 provided in 1J are arranged separately, and a plurality of charged coal leveling devices 12 are installed in parallel on the same leveling wheel 1J.

The coke pusher 3 is a coke pusher 4 consisting of a coke pusher beam that slides back and forth within the coke 2 of the coke oven 1.
It is equipped with a traveling drive device (not shown) and a furnace lid removal device (not shown). The charged coal leveling wheel 11 has a charged coal leveling device 12 consisting of two charged coal leveling beams that slide back and forth along the inner wall surface of the upper part of the kiln 2, as shown in the drawing. These beams are arranged parallel to each other with a 3-square pitch interval between them, and the interval can be determined according to the desired kiln pitch. The charging coal leveling wheel 11 has a traveling drive device (not shown) and a small lid opening/closing device for the furnace lid (not shown).

A coke guide wheel 5 is arranged on the other side of the furnace 1.

The coke guide car 5 has an extruded coke guide device 6 made of a cage that slides back and forth toward the window 2 and comes into contact with the opening edge of the window 2, and a traveling drive device (
(not shown) and a furnace lid removing device (not shown). A container 8 for accommodating extruded coke for a plurality of cavities of the furnace 1 is provided in a coke conveying car 7 disposed on the anti-furnace side of the coke guide car 5.

The container 8 for accommodating the extruded coke may be a closed packet with a lid that can be opened and closed at the top or a container with an open top, and the capacity of one packet or open container may be the extruded coke storage capacity for multiple furnaces. The same packets or open containers may be formed to have the capacity of one kiln and arranged side by side as shown in the drawings. The carrier vehicle 7 is connected to a traction train 17 having a running drive device, etc., and is connected to a dry cooling device (GIDQ) (not shown) or a wet cooling device (fire tower) (not shown) and the coke oven 1. Run. Further, a coal charging car 9 equipped with coal charging devices 10 for multiple kilns is arranged on the top surface of the furnace of the opening door 1. The coal charging device 10 is composed of four hoppers as shown in the drawing. The kiln units are arranged in two rows with an interval of three square pitches as described above, and the interval can be determined depending on the desired kiln pitch. The coal charging car 9 has a running drive device (not shown) and a lid mounting M (not shown).The one indicated by 13 in the figure is a running rail installed on one side of the above-mentioned furnace 1. , ]4.1
5 is the running rail laid on the other side of the opening door 1, 16 is the running rail on the other side of the opening door 1
18 is a coal tower, and 19 is an end deck of the coke oven 1.

Therefore, the coke pusher 3 is run along the running rail 13 on one side in the direction of the arrow a shown in the drawing, and the coke pusher 4 is aligned with the predetermined cavity 2 and stopped.
The vehicle is caused to travel in the direction of the arrow a along the running rail 14 on the other side, and is stopped with the extruded coke guide device 6 aligned with the window 2, and the transport vehicle 7 is also run on the running rail 15 in the direction of the arrow a. The vehicle is caused to travel, and one of the extruded coke storage containers 8 is engaged with the guide device 6, and the vehicle is stopped.

In this state, the pusher wheel 3 and the coke guide wheel 5 each operate a furnace lid removing device to remove the furnace lid (not shown). When the extrusion device 4 is operated to extrude the coke in the oven 2, the coke extruded from the oven 2 is introduced into one of the containers 8 through the guiding device 6 and stored therein. I can do it. After completing the coke extrusion work inside the temple 2,
The pushing car 3 and the coke guide car 5 each operate a furnace lid device to attach the furnace lid to the window 2, and travel to the next predetermined recess 2, and the transport car 7 also operates the furnace lid device to attach the furnace lid to the window 2, and travels to the next predetermined depression 2. 2
The transport vehicle 7 engages the other storage container 8 with the guide guide 6 and performs the coke extrusion work from the next cavity 2 in the same manner as described above. When the work is completed, the transport vehicle 7 heads toward the cooling device. and drive. Then, the same coke extrusion operation as described above is repeated. Next, the coal charging car 9 is driven from the coal tower 18 along the traveling rail 16 in the direction of the arrow a, and the coal charging device 10 is moved to each of the above-mentioned kilns 2 where the extrusion work has been completed.
When the vehicle stops, the undefeated device is activated to remove the covers from each window 2. Then, the coal charging devices 10 can be operated to charge coal into each cave 2. The charging coal leveling car 11 is also on the above traveling rail] 3 with arrow a
The charged coal leveling device 12 is aligned with each of the above-mentioned caves 2 and stopped, and the small lid opening/closing device is operated to open each of the above-mentioned kilns 2.
By opening the small lid of the furnace lid attached to the furnace lid and sliding the leveling device 12 back and forth into the cave 2 through the small lid, the charged coal can be leveled.

Since the present invention is based on the above-mentioned method and apparatus 1F, the coke pusher car 3 and the charged coal leveling car 11 can be arranged separately, so that the interpolating car 3 can be replaced with the coal charged by the coal charging car 9. Since there is no need to perform leveling work, the coke extrusion work of each kiln 2 can be performed in advance without being restricted by the charging car 9, and the coke transport car 7 accommodates the extruded coke of a plurality of windows 2. This not only significantly reduces the number of times the extruded coke is conveyed by the conveying vehicle 7 and the conveying time, thereby increasing the operating time of the extruding vehicle 3 and the guide vehicle 5, and significantly improves the coke extruding work efficiency. Later, the coal charging and charging coal leveling operations of the windows 2 are carried out by the coal charging car 9 and the charging coal leveling car 11.
This has the practical benefit of significantly reducing the traveling time of the coal charging vehicle 9 and significantly improving the efficiency of coal charging into the window 2 and coke productivity.
