Description

  [Technical Field] The present invention relates to a temporary coke oven, and there is no operational influence on facilities (extruder, coal charging vehicle, guide car, fire extinguisher, coke car) indispensable for coke production operation by the construction of the temporary home. TECHNICAL FIELD The present invention relates to a temporary building for a coke oven that makes it possible to construct a furnace and a coke oven facility equipped with the temporary building.

  Blast furnace coke is produced, for example, through the following steps (1) to (5).

  (1) First, the coal that has been transported is loaded into the coal yard. Next, the coal is transported to a blending tank by a conveyor line, and different brands of coal are put into several to several tens of blending tanks. The blending tank is equipped with a quantitative cutting device at the bottom, and blends by cutting out each brand at a constant rate. (2) Next, the coal is transported to the pulverized coal facility, and the particle size distribution is regulated by pulverizing the coal with the pulverizing facility.

  (3) The blended and crushed coal is sent to the coal tower of the coke oven by a conveyor line. In the coke oven, a carbonization chamber for carbonizing coal and a combustion chamber for burning fuel gas are alternately arranged to form a furnace group. The coal loaded vehicle that receives the coal from the coal tower travels to a predetermined carbonization chamber and charges the coal into the carbonization chamber.

  (4) When the carbonization of coal is completed in the carbonization chamber and coke is formed, the extruder opens the furnace lid of the carbonization chamber and extrudes red hot coke. The guide car is located on the opposite side of the extruder across the carbonization chamber and runs on the middle work floor. When the guide car extrudes the red hot coke in the carbonization chamber, the furnace lid of the carbonization chamber on the guide car side is opened, and the red hot coke that is pushed out is guided to the coke car.

  (5) When a coke car that has received red hot coke travels to CDQ (dry fire extinguishing equipment), CDQ cools the red hot coke with an inert gas. When the CDQ cannot be operated or the coke car cannot be driven, the fire extinguisher is driven instead of the coke car. When the fire extinguisher travels to the fire extinguisher (wet fire extinguishing equipment), the fire extinguisher sprinkles water to cool the red hot coke.

  As the coke oven equipment, for example, as shown in FIG. 13 shown as the embodiment of the present invention, one or a plurality of coke ovens A to D are arranged in series at intervals with the coal tower 2 interposed therebetween. The efficiency of repetitive operation of the coal charging vehicle 4 is improved by receiving the coal from the tower 2 into the coal charging vehicle 4 and then charging the coal into the carbonizing chambers 10 of the coke ovens A to D. .

  It takes several years to build a coke oven, and the work is diverse, including civil engineering, architecture, machinery, instrumentation, and furnace construction. When the concrete foundation of the coke oven body is completed, brickwork begins on it. The brickwork period is long. Since wind and rain are enemies when bricking, the main body of the coke oven to be bricked is covered with a temporary coke oven house.

Conventionally, as shown in FIG. 17, when the temporary upper house 33 for the coke oven is provided, the pillar 35 on the extruder 36 side is the rail level of the extruder 36 with respect to the pillars 34 and 35 that support the temporary upper house 33. It is known that the guide wheel 37 is installed on an intermediate work floor (platform) 38 on which the guide wheel 37 travels (see, for example, Patent Document 1).

Since the installation position of the column 15 is a position near the end of the end retaining wall 3 in the width direction, an operation of providing an anchor hole for fixing the lower end of the column is also easy (on the right side of FIG. 15, The plane arrangement of the front and rear columns 15 on one end side is shown).

  In such a form, there is no need to embed the anchor bolt 17 in the end retaining wall 3, so there is no need to drill an anchor hole at a high level position from the upper surface side of the end retaining wall 3. An anchor hole can be constructed in the concrete foundation 8 such as a concrete slab, and the position of the lower end of the column 15 can be easily fixed.

As a modification of the sixth embodiment, a coke oven is used so as to cover a central coke oven B in a configuration in which three coke ovens A, B, and C are continuously provided at intervals in series. In the form in which the temporary building 1 is provided, the column 15 on one end side in the longitudinal direction and the column 15 on the other end side in the temporary building 1 for coke oven are arranged in the gap between the adjacent end retaining walls 3 with a space therebetween. It is installed on a concrete foundation 8 such as a concrete slab.
Since other configurations are the same as those of the above-described embodiment, the same elements are denoted by the same reference numerals and the description thereof is omitted.

  When implementing this invention, you may make it install in the temporary building 1 for coke ovens the door for carrying in bricks, moving equipment, such as a hoist, and the ventilation fan for the purpose of ventilation of a construction place. For example, when a wall is provided on the end face side, a door for carrying bricks may be provided, and a hoist traveling girder is fixed over the lower side so as to be supported by the shed beam 14, It is also possible to provide a moving equipment for supporting the hoist so that it can run, or to install a ventilation fan for the purpose of ventilating the building construction site.

  In the said embodiment, although the roof wall of the upper house in the temporary building 1 for coke ovens uses the steel plate, in addition to a steel plate, it is a film-like member like cloth cloth like a tent cloth, for example, a roof It is also possible to construct a wall.

  Moreover, when implementing this invention, you may make it lighten by giving a buoyancy to the roof of a temporary upper house, for example, applying the principle of a balloon, the air in the temporary building 1 for coke ovens is used. Heating the furnace to a level that does not hinder the furnace, reducing the specific gravity of the air in the coke oven temporary building 1, positive pressure in the temporary upper house, and inflating the roof wall of the temporary house outward Thus, the burden on the steel frame including the columns of the temporary building for the coke oven may be reduced.

  In the illustrated embodiment, the brick building construction is performed at the end of the existing coke oven. However, when construction is performed at a place other than the end, the coal charging vehicle 4 needs to travel on the brick construction. Therefore, it is also possible to take appropriate safety measures and to run by installing a girder or rail for running the coal charging vehicle 4.
