Description

  The present invention relates to a temporary coke oven for covering a coke oven when the coke oven is newly installed or repaired.

  The walls of the coking oven carbonization chamber and combustion chamber are constructed by stacking refractory bricks. When stacking refractory bricks and raising the temperature of the stacked refractory bricks due to the installation or repair of a coke oven, it is necessary to prevent the stacked refractory bricks from being exposed to the wind and rain. Is covered with a temporary building called a temporary roof. The temporary coke for a coke oven described in the following Patent Document 1 has a coke oven when the coke extrusion direction is defined as the width direction, and the coke oven carbonization chamber and combustion chamber arrangement direction orthogonal thereto is defined as the furnace group direction. By constructing an upper roof above the wall part called the retaining wall at the end of the furnace group and the pillar part called the back stay of the coke oven, we repaired some of the coke ovens in particular among the coke oven groups. When doing so, the movement of the charcoal car, the extruder, the coke car, the guide car, the fire extinguisher, etc. is not disturbed.

However, since the temporary roof for coke ovens described in Patent Document 1 is configured to construct an upper roof above the retaining wall and the backstay, the area covered by the roof is narrow. In particular, when a new coke oven is installed, the coke oven needs to be large enough to cover the entire coke oven. In addition, especially when a coke oven is newly installed adjacent to an existing coke oven, a moving machine that must be repaired on the rails in the maintenance area between the existing coke oven and the new coke oven is frequently heated. A guide car that is exposed to coke may be used, and it is not necessary for all other moving machines to move to the newly installed coke oven.
The present invention has been made paying attention to the above-mentioned problems, and in particular, when a coke oven is newly installed adjacent to an existing coke oven, it has an area that completely covers the new coke oven and guides. The object is to provide a temporary roof for a coke oven that can be easily repaired.

  In order to solve the above problems, a temporary coke oven for a coke oven according to the present invention is a temporary coke oven for a coke oven used when newly installing or repairing a coke oven, above the new coke oven and A cantilever projecting from the lower side of the upper roof toward the outside of the coke oven in the coke oven, and a side wall that is suspended from the cantilever and can be folded and stored toward the inside of the coke oven in the coke oven direction And a section.

Further, the cantilever is projected toward the existing coke oven side.
In addition, the side wall portion is configured by connecting long sides of a long and narrow plate material that is long in the vertical direction so that the long sides can be bent, and the cantilever is made of H-shaped steel in which a flange portion is arranged in the vertical direction. A roller is disposed on the flange portion, and the side wall portion is suspended from the roller.

Thus, according to the temporary roof for a coke oven of the present invention, a cantilever beam is projected from the upper side of the newly installed coke oven and from the lower side of the upper roof toward the outside of the coke oven in the furnace group direction. Since the side wall that can be folded and stored is hung from the cantilever toward the inside of the new coke oven, the cantilever is used when a coke oven is newly installed adjacent to the existing coke oven. By projecting toward the existing coke oven side, the guide car can be repaired in the maintenance area with the existing coke oven, and the area of the temporary roof is covered completely with the new coke oven. Can be wide.
Further, the long sides of the vertically long and narrow plate members are connected so as to be bendable to form a side wall portion, and a roller is disposed on the flange portion of the cantilever made of H-shaped steel, and the side wall portion is suspended from the roller. By lowering, the side wall can be folded and stored easily.

1 is an overall front view showing an embodiment of a temporary roof for a coke oven according to the present invention. It is a side view of the temporary roof for coke ovens of FIG. FIG. 3 is a detailed view of a cantilever and a side wall portion of the temporary roof for the coke oven of FIG. 2. It is a side view which shows an example of the temporary temporary roof for conventional coke ovens.

Next, an embodiment of a temporary coke oven for a coke oven according to the present invention will be described with reference to the drawings.
1 and 2 show a state in which the coke oven temporary roof according to the present embodiment is built on a new coke oven adjacent to an existing coke oven. In these drawings, reference numeral 1 is a newly installed coke oven, and reference numeral 2 is an existing coke oven. A combustion chamber (not shown) is adjacent to the carbonization chamber 3 of the new coke oven 1 in the direction perpendicular to the paper surface. By burning fuel gas in the combustion chamber, the coal in the carbonization chamber 1 is dry-distilled to produce coke. To do. In FIG. 1, an extruder rail 4 for an extruder is disposed on the right side of the drawing with respect to the carbonization chamber 3. On the other hand, a guide wheel 5 is disposed on the left side of the carbonization chamber 3 in the drawing, and a fire extinguishing vehicle 6 is disposed below the guide wheel 5. These guide wheels 5 and fire extinguishing vehicles 6 are movable along the rails in the direction perpendicular to the drawing sheet.

  A furnace bottom 7 is formed below the carbonization chamber 3 and the combustion chamber. In the present embodiment, the flue 8 is formed on both sides of the furnace bottom 7, and inside the furnace bottom 7, a coke oven gas pipe 9 for feeding a gas generated in the coke oven, so-called coke oven gas, A blast furnace gas pipe 10 for supplying gas generated in the blast furnace is installed. Coke oven gas and blast furnace gas are used as fuel gas in the combustion chamber by coke oven gas alone or mixed with blast furnace gas depending on the operating conditions of the coke oven.

  As described above, since the extruder and the guide wheel are arranged on the left and right sides of the new coke oven 1 shown in FIG. 1, the left-right direction in FIG. 1 is the coke extrusion direction (the vertical direction in FIG. 2). If the coke extrusion direction is the width direction and the direction perpendicular to the coke extrusion direction is the furnace group direction, the left-right direction in FIG. 2 corresponds to the furnace group direction (the direction perpendicular to the paper surface in FIG. 1). The coke ovens 1 and 2 are each constructed between retaining walls 11 that are erected at a predetermined interval in the furnace group direction. Further, back stays 12 are erected on both ends of the coke ovens 1 and 2 in the width direction, and a platform 13 is constructed outside the back stays 12. The space between the retaining walls 11 where the coke ovens 1 and 2 are not constructed is called an intermediate deck 15 and is used as a maintenance area of the guide wheel 5, for example.

  Since the new coke oven 1 is constructed on the left side of the retaining wall 11 on the left side in FIG. 2, the upper roof (this upper roof is also referred to as a shed) 14 is illustrated from the retaining wall 11 on the left side in FIG. It extends to the outer left retaining wall. In addition, the temporary coke oven for the coke oven of the present embodiment has a pillar standing on the platform described above, and an upper roof 14 provided on the pillar, so that the newly installed coke oven 1 is wide enough to cover. Can do. In the present embodiment, the cantilever 16 is disposed toward the existing coke oven 2 side, that is, toward the outer side of the coke oven, in particular, from the lower side of the upper roof 14 on the guide vehicle 5 side and the upper side of the new coke oven 1. Project. And the side wall part 17 which can be folded and accommodated is hung from this cantilever 16 inside a coke oven furnace group direction.

  The side wall portion 17 has a so-called accordion curtain shape in which long sides of a long and narrow plate member that is long in the vertical direction are connected so as to be bendable. Further, as shown in FIG. 3, the cantilever 16 is made of H-shaped steel having a flange portion disposed in the vertical direction. A roller 18 is disposed on the lower flange portion of the cantilever 16 made of H-shaped steel, and the side wall portion 17 is suspended from the roller 18. Thereby, the roller 18 rotates along the flange portion of the cantilever 16 so that the accordion curtain-like side wall portion 17 can be easily folded and housed or expanded.

  At the normal time, the side wall portion 17 is expanded as shown in FIG. 2a. For example, when the usual guide wheel 5a is broken, the side wall portion 17 is folded and stored as shown in FIG. 2b. When the side wall portion 17 is folded and stored in this way, in the case of the present embodiment, a space for storing two guide wheels 5 can be created on the intermediate deck 15, and a regular guide is provided on the side of the newly installed coke oven 1. It is possible to continue the operation of the coking chamber at the end of the existing coke oven 2 by putting the individual guide wheels 5b on the intermediate deck while repairing the vehicle 5a. As is well known, the guide wheel 5 is frequently exposed to high-temperature coke, so that the repair frequency is high.

  FIG. 4 shows a normal coke oven temporary roof without a folding side wall. In this case, a pillar 101 for indicating the upper roof 14 is erected at the position of the retaining wall 11 on the left side of the drawing. Since the guide wheel 5 interferes with the pillar 101, the guide wheel 5 cannot move to the left of the figure from the pillar 101. For this reason, only one guide wheel 5 can be stored in the intermediate deck 15, and in the unlikely event that this guide wheel 5 breaks down, the end kiln of the existing coke oven 2 cannot be pushed out. Department must be shut down.

Thus, in the temporary coke oven for the coke oven of the present embodiment, the cantilever 16 is projected from the upper side of the newly installed coke oven 1 and from the lower side of the upper roof 14 toward the outside of the coke oven furnace group. When the new coke oven 1 is newly installed adjacent to the existing coke oven 2 by suspending the side wall 17 that can be folded and stored from the beam 16 toward the inside of the new coke oven 1 in the direction of the furnace group, this piece is provided. By projecting the cantilever 16 toward the existing coke oven 2 side, two guide wheels 5 can be simultaneously stored in the intermediate deck 15 between the existing coke oven 2 and the upper roof 14. The area can be an area that completely covers the new coke oven 1.
Further, the long sides of the long and narrow plate members extending in the vertical direction are connected so as to be bendable to form the side wall portion 17, and a roller 18 is disposed on the flange portion of the cantilever 16 made of H-shaped steel. By suspending the side wall part 17, the side wall part 17 can be easily folded and stored and expanded.
