Description

  The present invention relates to an apparatus for scraping out clogged coke when the coke is clogged in the coke oven and cannot be fired by an extruder.

  Conventionally, coke generated in a coke oven is kiln out by an extruder. At this time, a state in which the extruder cannot properly kiln may occur. This is mainly due to the fact that carbon adheres excessively to a part of the furnace body, or that the coke clogging phenomenon occurs because the furnace wall is worn with long-term operation of the coke oven. As a means for scraping out coke in the coke oven, a technique has been proposed in which a scoop is attached to the lower front portion of the ram of the extruder and the coke in the furnace is scraped out by retreating the ram (see Patent Document 1). ). In addition, there is a means for arranging a railing machine dedicated to scraping independent of the extruder without using the ram of the extruder.

No. 05-43083

  However, in the invention disclosed in Patent Document 1, the ram head and the ram beam of the extruder together with the scoop are exposed to a furnace temperature of about 1000 ° C. every time the scraping operation is performed, along with the operation of scraping the clogged coke. . For this reason, the wear rate of the ram or the like is greatly accelerated compared to when it is used only for the original extrusion operation, and therefore the service life is reached in a period shorter than the normal service life. For this reason, new rams and the like must be purchased at intervals shorter than the initial service life, which increases the operating cost of the coke oven as a whole.

  In addition, in the case of means for arranging a railing machine dedicated to scraping that is independent of the extruder, although the problem of wear of rams can be solved, the scraping work is used on the same rail (railway) as the extruder It will be. Therefore, when each machine moves in parallel in front of the furnace port and changes its position, it will interfere with each other at any position on the rail (rail). Therefore, in order to switch the position of each machine, it will be necessary to separately lay in the form which adds the retreat place and retreat apparatus of a rail machine to the existing rail installation in the place before a coke oven. However, it is often difficult to install such new facilities on the site of existing coke oven facilities due to layout restrictions.

  The present invention has been made in view of the above problems, and the clogged coke scraping device is a dedicated machine that does not use an extruder ram or the like, and a new retreat location and retreat device are provided in the coke oven equipment.

As a result, jacking-up force is applied to the lower structure 30 with the contact surface between the rail running wheel 39 and the upper surface R of the rail 56 as a fulcrum. Accordingly, the pedestal 31 to which the outrigger leg 36 is attached is raised, and the floor running wheel 33b at the end of the pedestal leg 32 is detached from the floor G. The height of the base 31 is determined by adjusting the heights of the four outrigger legs 36 and fixing them at predetermined positions. In this way, the jammed coke scraping device 1 of the present invention is suspended on the rail 56 (operation 4).

Next, the upper structure 10 is raised by the lift device 60, and the beam 12 is raised to the height of the furnace port 51 of the carbonization chamber 50a (operation 5).
FIG. 9 is a diagram showing the operation of scraping work of clogged coke. In the drawing, a part of the outer surface of the outrigger leg 36 is omitted to show the internal jack structure.
First, as shown in FIG. 9, the turntable 62 is rotated, and the upper structure 10 is turned by approximately 90 degrees so that the scoop 11 faces the furnace port 51 (operation 6).

  Then, the rack driving device 20 is driven to advance the beam 12 forward. Accompanying this forward movement, clogged coke (not shown) with the tip of the scoop 11 and the hypotenuse of the side plate 11a adhering to the furnace wall and bottom of the carbonization chamber 50a is scraped off. The clogged coke thus scraped off is held in the internal space of the scoop 11. When the scoop 11 reaches a predetermined position, the rack driving device 20 is stopped and the beam 12 is stopped (operation 7).

  Thereafter, the rack driving device 20 is driven in the reverse rotation to the above, and the beam 12 is retracted. As a result, the scoop 11 and the beam 12 are returned to their original positions before starting the forward movement. At this time, a stopper (not shown) provided on the base 28 of the upper structure 10 pushes up the lower part of the scoop 11 as the beam 12 moves backward, using the power when the beam 12 moves backward. The bottom plate 11b of the scoop 11 is inclined toward the chute 27 disposed below. Then, the clogging coke held in the scoop 11 is dropped onto the chute 27 disposed below the scoop 11 (operation 8).

The clogging coke scraping apparatus 1 of the present invention scrapes out clogging coke in the target carbonization chamber 50a by repeating the above operation as appropriate. After this, when scraping out the coke 80 in another carbonization chamber 50a, the wheel stopper that makes the rail traveling wheel 39 of the lower structure 30 non-rotatable is opened to be rotatable, and the next carbonization chamber 50a is rotated. What is necessary is just to run on the rail 56 and move to the front. In the case of interference with the extruder 52 during the movement, the procedure reverse to the above, that is, the upper structure 10 is turned and then lowered, the outrigger leg 36 is shortened, and the floor running wheel 33b of the pedestal leg 32 is shortened. Is placed on the floor G. And the outrigger arm 37 is shortened inside, and the width | variety of the clogging coke scraping apparatus 1 is shortened. Then, the upper structure 10 may be separated from the lower structure 30 as described above.
The clog coke scraping apparatus 1 of the present invention is a space on the floor G sandwiched between the two rails 56 for the extruder 52 as described above, and the union operation and separation by the upper structure 10 and the lower structure 30 are performed. The scraping operation can be performed by combining the operations.

(Effects of the first embodiment)
In the first embodiment of the present invention, the height of each of the upper structure 10 and the lower structure 30, and the length in the short direction in the horizontal direction are set in the gap S below the machine base 53 of the extruder 52. Since the height and length allow passage, the upper structure 10 and the lower structure 30 can each pass through the gap S. Therefore, since the overall height when the upper structure 10 is supported by the lower structure 30 is higher than the height of the gap S, the clog coke scraping device 1 and the extruder 52 of the present invention that are connected as they are can be connected to each other. Even in the case of interference, the interference can be avoided by separating the upper structure 10 and the lower structure 30. Of course, the length in the lateral direction of each of the upper structure 10 and the lower structure 30 is set to a length that can pass through the gap S below the machine base 53 of the extruder 52.

  Further, since the upper structure 10 is configured to be rotatable with respect to the lower structure 30, the major axis of the upper structure 10 can be freely switched vertically or parallel to the coke oven 50. Therefore, even if it is a case where it interferes with the extruder 52 if the long axis of the upper structure 10 remains perpendicular to the coke oven 50, the long axis of the upper structure 10 is switched in parallel to the coke oven 50. Thus, it is possible to avoid the upper structure 10 from interfering with the extruder 52.

(Second embodiment)
A second embodiment of the present invention will be described. In addition, the structure of the clogging coke scraping apparatus 1 which concerns on 2nd embodiment of this invention is schematic, and the upper structure 10 and the lower structure 30 which concern on the said 1st embodiment are connected and integrated, without isolate | separating. It has been done. The overall height and overall width of the integrated clog coke scraping device 1 are set to a height and a width that can pass through the gap S under the machine base 53 of the extruder 52. Therefore, the configuration, operation, and effect of the second embodiment will be described in detail only for the parts different from the first embodiment, and the description for the equivalent parts will be omitted.

The lower structure 30 according to the second embodiment of the present invention is different from the lower structure 30 according to the first embodiment in that the winch 41 and the base traveling wheel guide 49 are not provided. Are the same.

  The overall height when the upper structure 10 is supported by the lower structure 30 and the overall length in the short direction in the horizontal direction define the gap S below the machine base 53 of the extruder 52. The height and length that can be passed. For this reason, the upper structure 10 and the lower structure 30 are configured with the dimensions of each part after the upper limits of the height and width are calculated.

The connection part which concerns on 2nd embodiment of this invention is set as the structure by which an upper coupling part and a lower coupling part are connected, and the upper structure 10 and the lower structure 30 do not isolate | separate.
