Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to coke dry fire extinguishing equipment, and in particular simplifies the structure of the frame on which the charging device for charging red-hot coke into the fire extinguishing tower is mounted. The present invention relates to a coke dry fire extinguishing system that can reduce the cost of the equipment and increase its strength as much as possible against loads such as earthquakes.

[Conventional technology]

Generally, for coke dry extinguishing equipment, the first
As shown in the figure, a coke dry fire extinguishing tower 1 (hereinafter referred to as a fire extinguishing tower) and a charging device (not shown) for charging red-hot coke, etc. surrounding the outer periphery of this fire extinguishing tower 1 are installed. A frame 2 on which the structure is placed is erected from the same foundation 3.

The side walls 4 etc. that partition the fire tower 1 have a thickness of about 1
It mainly consists of a wall 5 of 1.5 m to 1.5 m and made of firebrick or the like, and an iron skin of about 10 mm thick covering the outside for the purpose of gas sealing.

The frame 2 has several columns 7 erected around the fire tower 1, and a crane girder floor 9 on which a hoist 8 for transporting red-hot coke, etc. is installed at the top is placed between each column 7. It's being passed around. A red-hot coke charging port 11 is provided at the top 10 of the fire tower 1, and a charging floor 12 where a charging hopper (not shown) etc. is installed is also located at the same height.
is provided.

[Problem that the invention attempts to solve]

By the way, in this frame 2, the parts on which a large load acts are the charging floor 12 where the charging hopper etc. are installed, and the crane girder floor 9 where the hoisting machine 8 etc. is installed. In particular, the hoist 8 installed at the top has the heaviest weight among other devices, and when transporting the red hot coke, it travels on the crane girder floor 9 with the added weight of the red hot coke. , the frame 2 will be shaken greatly. In addition, in the event of an earthquake, it had a heavy section at the top, making it the most stable and weakest structure structurally.

Furthermore, coke dry extinguishing equipment is not a facility for production purposes, but is a facility for energy saving purposes, and economic efficiency is the most important factor in such facilities. Evaluating the above structure from this perspective,
A large amount of equipment cost is spent on structural members for reinforcement, which is a disadvantage as an energy-saving equipment.

Another problem is that the steel skin 6 of the fire tower 1 has a thin plate thickness relative to its own weight and rigidity.
Although it is easy to mold, it is difficult to maintain the shape after it has been specified by molding, resulting in poor manufacturability.

The present invention has been devised in view of the above-mentioned problems and to effectively solve them.

The purpose of the present invention is to simplify the structure of the frame, reduce the equipment cost, and
An object of the present invention is to provide a coke dry fire extinguishing system that can increase its strength as much as possible against loads such as earthquakes.

[Means for solving problems]

The present invention covers the outside of the side wall of the body of a coke extinguishing tower, which has a coke charging port at the top for charging red-hot coke, with a thick iron shell to form a body with sufficient rigidity. A shoulder is formed along the circumferential direction at the upper end of the body, a support is raised from the shoulder to form a frame, and the frame is equipped with a device for charging red hot coke into the coke charging port. It is equipped with a red-hot coke charging device including a charging hopper.

[Effect]

Because the frame was formed by raising columns from the shoulders of the body, which has sufficient rigidity, the height of the frame itself could be lower than that of a structure constructed by raising columns from the foundation of a coke fire tower. Therefore,
The frame is difficult to shake and is easy to construct.

〔Example〕

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 2, the coke dry fire extinguishing equipment according to the present invention has a coke dry fire extinguishing tower 1 (hereinafter referred to as fire extinguishing tower) that stands approximately at the center of a foundation 3 with a coke charging port 11 located at its top 10. It is formed as follows.

The fire extinguishing tower 1 consists of a body part 13 formed into a substantially cylindrical body with an outer diameter of about 10 to 15 m, and a head part 14 connected to the upper end of the body part and whose diameter gradually decreases upward. In addition, the maximum outer diameter of the lower end of the head 14 is smaller than the outer diameter of the upper end of the body 13, and therefore a step is created at the connecting portion due to the mutual diameter difference, and the upper end of the body side wall 4 is flattened along the circumferential direction. A shoulder portion 15 having a circular annular surface is formed.

The side wall 4 that partitions the body 13 of the fire tower 1 is
A wall 5 is formed on the inner periphery of firebrick or the like with a thickness of 1 to 1.5 m, and is constructed with sufficient rigidity in terms of strength. Further, on the outer periphery, an iron skin 6 having a thickness sufficient to support a frame 2, which will be described later, covers the outside of the wall 5 and also serves as a gas seal.
Therefore, since the iron skin 6 once formed has a sufficient thickness, it does not easily lose its shape and is easy to manufacture.

The frame 2 is located at the upper end portion of the body side wall 4, that is, at the shoulder portion 1.
In the illustrated example, a pedestal 16 is provided on the shoulder 15 to support the column 7 centering on the upper end of the iron skin 6 of the side wall 4.
A support 7 is raised from the pedestal 16.
At the top of the support column 7 is a crane girder floor 9 on which a hoist 8 etc. for transporting red hot coke etc. is installed.
is strung between each pillar 7. In the illustrated example, one end of the crane girder floor 9 is overhanging, and its tip is also supported by a support 17 that stands up diagonally from a pedestal 16.

Further, at a height position of the coke charging port 11, a charging floor 12 on which devices such as a charging hopper 18 are installed is spanned between the respective supports 7.

The frame 2 configured in this manner has short columns 7, and therefore, the structure 2 itself has a small deflection of the columns 7 against shaking caused by an earthquake or the running of the hoist 8, and its strength is high. Moreover, the number of steel materials constituting this frame 2 can be reduced.

The body 13 that supports the support column 7 has sufficient rigidity to support the frame due to the thick cylindrical iron shell 6 and the inner wall 5 made of refractory bricks.

[Effect of idea]

As is clear from the above description, the present invention provides the following excellent effects.

(1) Cover the outside of the side walls of the body of a coke fire extinguishing tower with a thick iron skin to form a body with sufficient rigidity, and form a frame by raising columns based on the shoulders of the body. Therefore, the height of the frame itself can be lowered compared to a structure in which columns are raised from the foundation of a coke fire extinguishing tower, and the frame is less likely to shake, increasing its strength and making it easier to construct.

(2) Therefore, the number of reinforcing members is reduced, and equipment costs can be reduced, including the reduction in the length of the columns.

(3) The structure is simplified and can be easily adopted.
