Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a furnace frame deposit device used when replacing a furnace frame in a coke oven.

[Prior Art] In a coke oven, a furnace lid that closes the furnace opening of the carbonization chamber is attached by a knife edge for sealing to a cast iron furnace frame that is attached to the entire circumferential surface of the end of the furnace opening. ing.

The furnace frame is deformed and damaged due to the severe environment. When the furnace frame is deformed or damaged, problems such as gas leakage and dropping of the furnace lid occur. Therefore, the furnace frame thus deformed or damaged must be replaced with a new furnace frame at any time for repair.

Conventionally, the replacement of the furnace frame is performed by removing the furnace frame from the furnace opening with a furnace frame attaching / detaching device, and removing the removed furnace frame by an extruder or the like moving in front of the furnace, between the coke oven furnace group and the furnace group. Move to the body space part and hang it on the ground in the furnace space part with a crane etc., while moving the repaired new furnace frame in front of the furnace in the reverse order of the above and attach it to the furnace mouth Was there.

[Problems to be solved by the device]

In the above-mentioned replacement of the furnace frame, it is not easy and dangerous to replace the furnace frame with a crane or the like in the space of the furnace body because there are ascending pipes and other equipment above the furnace frame. However, there was a problem that the repair cost increased significantly.

Therefore, an object of the present invention is to provide a device capable of safely, easily, and quickly replacing a furnace frame in a coke oven.

[Means for solving the problem]

In this invention, in the furnace body space portion between the coke oven furnace group and the furnace group, vertical shafts attached to the upper and lower parts of the columns installed at predetermined intervals in the length direction of the furnace body, And a furnace frame receiver rotatably attached to the vertical shaft from a position in the length direction of the furnace body to a position at a predetermined angle,
The furnace frame receiver is a bottom frame on which the furnace frame is placed in a vertical state,
It is characterized in that it is constituted by a side frame that supports the furnace frame and has substantially the same height as the furnace frame.

 Next, the invention will be described with reference to the drawings.

1 is a schematic front view showing an embodiment of the present invention, FIG. 2 is a schematic side view thereof, FIG. 3 is a schematic plan view thereof, and FIG.
The figure is a schematic layout plan view thereof. As shown in FIG.
A furnace body space C is provided between a furnace body A and a furnace body B which are composed of a plurality of furnace chambers, and a plurality of furnace body spaces C are provided at predetermined intervals in the furnace body length direction. The column 1 is installed. In FIG. 4, D is the extruder side, E is the fire engine side, and line F is the position of the furnace opening.

As shown in FIGS. 1 to 3, a vertical shaft 2 is attached to each of the upper part and the lower part of a predetermined pillar 1 in the furnace space C. The vertical frame 2 of the column 1 has a furnace frame receiver 3
Is pivoted. As shown by the broken lines in FIGS. 3 and 4, the furnace frame receiver 3 extends in the lengthwise direction of the furnace body, that is, the line F in FIG.
From the position in the direction indicated by (1) to the position of 90 degrees orthogonal to this, it can rotate to the extruder side D.

The furnace frame receiver 3 includes a bottom frame 5 on which the furnace frame 4 is placed in a vertical state, the bottom frame 5 having substantially the same width and thickness as the furnace frame 4, and a side frame 6 having substantially the same height as the furnace frame 4. ing. Wheels 8 that abut the bottom wall 7 of the furnace body are rotatably provided on the lower surface of the bottom frame 5 in order to support the furnace frame receiver 3 and smoothly rotate the furnace frame receiver 3.

On the lower surface of the bottom frame 5, there is provided a stopper 10 for fixing the furnace frame receiver 3 which can be inserted into a hole 9 provided in the bottom wall 7 shown in FIG. Further, as shown in FIG. 2, the top wall 11 of the furnace body is provided with a stopper 12 for abutting the upper portion of the side frame 6 of the furnace frame receiver 3 to control the rotation thereof.
Is provided with a stopper 13 for supporting the furnace frame 4.

The furnace frame receiver 3 is provided with an ascending / descending path 14 along the furnace frame receiver 3 and an inspection deck 15 at the upper end of the ascending / descending path 14.

[Action]

When replacing the furnace frame, the furnace frame attaching / detaching device removes the furnace frame from the furnace opening, and the removed furnace frame is moved along the line F to the position of the predetermined support 1 in the furnace body space C by an extruder or the like. Then, the furnace frame 4 is transferred to the furnace frame receiver 3 attached to the support 1, and the furnace frame 4 is deposited.

The furnace frame 4 is vertically mounted on the bottom frame 5, and the furnace frame receiver 3 supported by the side frames 6 is shown by broken lines in FIGS. 3 and 4 using a chain block or the like. As described above, the furnace side is rotated to the extruder side D from the position in the length direction, that is, the position indicated by the line F in FIG.

There is no riser or other equipment near this position. Therefore, the furnace frame 4 stored in the furnace frame receiver 3
Can be safely and easily hung on the ground by a crane or the like, and the replacement can be performed easily and quickly.

[Effect of device]

As described above, according to the present invention, the replacement of the furnace frame in the coke oven can be performed safely, simply, and quickly, and the repair cost can be reduced, which is industrially useful. .
