Hereinafter, preferred embodiments of a brick module taking-in device and a taking-in method in a coke oven according to the present invention will be described with reference to the drawings.
FIG. 1 is a cutaway perspective view showing a structural example of a coke oven. In the coke oven 100, the carbonization chambers 102 and the combustion chambers 103 are alternately arranged in the upper part of the heat storage chamber 101 (FIG. 1, arrow Y direction) to form a furnace group. The carbonization chamber 102 is a chamber for making coke by steaming coal. The combustion chamber 103 is a chamber for burning fuel gas, and is constructed from bricks. A coke oven is basically made of brick and is composed of many bricks stacked.

  Each carbonization chamber 102 has a depth of about several tens of meters (FIG. 1, arrow X direction), and blended and pulverized coal as a coke raw material is input. As shown in FIG. 2 at both ends in the depth direction X of the combustion chamber 103, the combustion chamber 103 formed by stacking bricks on the backstay 104 (104A), which is a reinforcing structure (support), is formed on both sides of the PS and CS. It is erected at almost the same height in a state where it is sandwiched from. The PS of the furnace group is provided with an extruder, and the CS is provided with ancillary equipment or equipment such as a guide car. Further, a platform 105 is provided along the furnace group length direction Y in the PS and CS of the furnace group. The CS platform is equipped with a rail for the guide car to travel.

FIG. 2 schematically shows the work contents of the kiln brick transshipment in the embodiment of the present invention. The brick transfer area 106 of the coke oven 100 is set in each of PS and CS, and the brick module 200 is moved to the place where the brick module take-in device 10 is installed by the mobile crane 1. Here, the operation of stopping the six carbonization chambers and the five combustion chambers and repairing the kiln bricks and backstays of the five combustion chambers is called “5-kiln repair”, and similarly nine carbonization chambers and eight combustion chambers are repaired. The operation to stop the operation of the combustion chamber and repair the eight combustion chambers is called “8 kiln repair”. Stopping the operation of 6 carbonization chambers, 5 combustion chambers, and repairing the kiln bricks in the five combustion chambers, the 5 kilns pile up the kiln brick modules in parallel at the same time. In addition, in the case of repairing 8 kilns, all the 8 firing chamber bricks are stacked at almost the same height.
Further, the backstay 104 cuts a corresponding portion and replaces the portion (replacement portion 104 </ b> A) with a new one (welding and joining) with the replacement of the brick.

  FIGS. 3A and 3B are a side view and a front view showing a configuration example of the CS brick module taking-in device 10. The brick module take-in device 10 includes a gantry 11 installed at a predetermined position of the coke oven 100, a guide rail 12 laid on the gantry 11 along the furnace group length direction Y, and a furnace group head supported by the guide rail 12. A trolley 13 that is movable along the direction Y is provided, and the brick module 200 is suspended by the trolley 13 so as to be movable up and down.

  The length of the gantry 11 in the furnace group length direction Y is set to be approximately equal to or longer than the plurality of furnaces to be repaired, and the trolley 13 can move in the furnace group length direction Y within the length range. Further, the gantry 11 is installed so as not to interfere with the running of the charging vehicle, the extruder and the guide vehicle. The charging vehicle travel interference range 106A is shown in FIG. 3A. And the mount frame 11 is installed on the furnace of the brick transshipment area 106 (CS) so that the guide rail 12 may follow the furnace group length direction Y. 3B includes a brick module taking-in area 106B on the right side.

  About the installation method of the mount frame 11, for example, an extension metal fitting etc. can be fixed by welding and attached to the upper end of the back stay 104 at both ends (and in some cases left in the middle) in the furnace group length direction Y. Alternatively, it can be attached to a bracket holding pipes such as dry mains and dust collecting pipes attached to the coke oven 100 by welding or the like, and further installed by placing the legs of the gantry 11 directly on the coke oven 100 can do.

  As shown in FIGS. 3A, 3B and 4, the trolley 13 is supported on the lower side of the guide rail 12 so as to be movable along the furnace group length direction Y. A chain 14 is suspended below the trolley 13, and the brick module 200 can be gripped by a clamp 15 connected to the chain 14.

  Further, in the CS brick module taking-in device 10, as shown in FIG. 3A, an auxiliary guide rail 16 extending outward from the coke oven 100 along the direction perpendicular to the furnace group length direction Y, that is, the depth direction X is provided. Have. The trolley 13 is supported so as to be movable along the depth direction X on the lower side of the auxiliary guide rail 16, the chain 14 is suspended below the trolley 13, and the brick module 200 is connected by the clamp 15 connected to the chain 14. Can be gripped.

  The auxiliary guide rail 16 is for enabling the brick module 200 to be taken in from the CS-side platform 105 on which the coke guide car runs, and a crane or the like cannot be installed in the CS. Thus, according to the auxiliary guide rail 16, the brick module 200 can be taken in from the platform 105 of the coke oven 100.

As specific methods for taking in the brick module 200, there are the following two methods.
A) Taking in from the furnace: With the mobile crane 1 (see Fig. 5) installed on the PS ground, lift it as much as possible on the CS side of the furnace, and hold it under the hoist of the gantry 11 by means of a trolley (manually pushed). Go. It can be taken to the trolley 13 of the capture device 10 from the brick module capture area 106B on the right side of the module capture device 10 of FIG. 3B.
B) Taking in from the platform: From the deck at the end of the furnace group, it is carried into the CS platform 105 (coke guide car traveling part) by a cart (pressed by human power), and under the hoist of the auxiliary guide rail 16 of the platform 11 (the length of the furnace group) Move in a direction perpendicular to the direction).
If it is possible to deal with (b), (b) is desirable. The reasons for this are (1) being far from the crane body, being very hot on the furnace, and being unable to work for a long time (in summer, there is a risk of heat stroke). B) is more suitable for actual work, but it is far from the deck where the repairing furnace is carried in, and it is difficult to bring the brick module to the truck so far, or the hoist of the auxiliary guide rail 16 is lifted The method of taking in from the furnace is also adopted.

  The brick module 200 transported to a predetermined position using the hoist of the mobile crane 1 or the like or the auxiliary guide rail 16 is received by the brick module take-in device 10 and attached to the guide rail 12 as shown in FIG. 3B. The trolley 13 is suspended and moved to a predetermined position in the brick transshipment area 106 (CS). The brick modules 200 are sequentially stacked, and the repair work is completed by stacking a predetermined number.

According to the brick module taking-in apparatus 10, in the case of CS, the brick module 200 can be taken in from the platform 105 of the coke oven 100 or can be taken in from the furnace top.
In addition, it can be carried out for two furnace ports adjacent to each other, and it is efficient because mortar coating work and stacking work can be performed alternately.

  6A and 6B are a front view and a side view showing a configuration example of the PS brick module taking-in device 10. The brick module taking-in device 10 is configured in substantially the same manner as in the case of CS, and a gantry 11 installed at a predetermined position on the furnace of the coke oven 100, and laid on the gantry 11 along the furnace group length direction Y. A guide rail 12 and a trolley 13 supported by the guide rail 12 and movable along the furnace group length direction Y are provided, and the brick module 200 is suspended by the trolley 13 so as to be movable up and down. In the case of PS, the brick module taking-in device 10 is installed after removing the rising pipe of the repair target kiln on the furnace. (The riser pipe is installed at the top of the brick transshipment area of each kiln, and it needs to be removed for repair.)

When the brick module 200 is taken in the PS, since the mobile crane 1 can be installed on the ground near the PS platform 105 as shown in FIG. 2, the brick module 200 is directly repaired by the mobile crane 1 in the combustion chamber to be repaired. 103 can be placed at the installation location. In that case, it is not necessary to move and carry on the platform 105 using a cart like CS.
In this case, the brick module 200 is piled up, and when the height is approximately in the middle, the crane boom tip comes into contact with the equipment above the place where the brick is stacked, such as a dry main pipe. Therefore, after that, the brick module 200 is hung on the stage 107 once made by the ground crane at the position of the brick module taking-in area 106B in the upper part of the dry main, and the hoist of the gantry 11 is taken to the installation place. For this reason, in the case of PS, about half of the brick modules 200 are directly suspended from the installation location to be repaired by a crane. A trolley that moves along the rail that extends outward from the coke oven to efficiently bring the brick module from the stage to the installation location is required, but the hoist 13 can also move on the stage 200, that is, outside the furnace. The guide rail 12 may be bent and installed.

As mentioned above, although this invention was demonstrated with various embodiment, this invention is not limited only to these embodiment, A change etc. are possible within the scope of the present invention.
In the above embodiment, an example of 5 kiln repair or 8 kiln repair has been described. However, the number of combustion chamber repairs is not limited to 5 or 8, and can be appropriately increased or decreased according to the number of repair kilns.
