Description

Detailed Description of the Invention The present invention relates to a receiving and charging method for coke dry extinguishing equipment for charging red-hot coke extruded from a coke oven into a cooling tower, and particularly relates to a method for charging red-hot coke to a charging port of a cooling tower. The present invention relates to a method for receiving and charging coke dry extinguishing equipment, which can reduce the hoisting load to be raised and significantly reduce the cost of the hoist and the frame supporting it.

Generally, coke used in steel manufacturing and the like is made by cooling red-hot coke discharged from a coke oven in a cooling tower.

Conventionally, when charging red-hot coke from a coke oven to a cooling tower, first a fixed operating charge of red-hot coke (for example, 28 tons) is pushed out from one kiln of the coke oven.
on) is received in one large coke packet 1 as shown in Fig. 1, which is conveyed to a cooling tower, and
The coke packets were hoisted up by a hoist in a hoisting tower, and the red-hot coke was charged into the cooling tower.

By the way, the temperature of the red hot coke loaded in the coke packet used in coke extinguishing equipment is i ooo ~
Heat resistance is required due to the high temperature of 1100℃, there is a limit on the height of the packet, and furthermore, the size of the coke bucket itself has to be changed due to reasons such as the need to process red hot coke in each kiln at once. And the weight has increased, and as a result, the hoisting load of the hoisting machine has become very large. For example, the weight of coke per oven is approximately 28 tons, and the hoisting load for hoisting up coke packets loaded with coke is 80 to 80 tons, including the weight of the bucket 1 itself.
It will reach even 90t:on. Therefore, although the weight of the red-hot coke charged at one time is relatively small at about 26 tons, the hoisting load that determines the size of the hoisting machine is large, so the conventional coke extinguishing equipment has two hoisting machines. The cost has become extremely large and the cost has increased significantly.

Furthermore, the size of each part of the frame supporting the hoisting machine is determined based on the load conditions of the hoisting machine, and as a result, the cost of the frame becomes very high.

The present invention has focused on the above-mentioned problems and has been devised to effectively solve them.

The object of the present invention is to provide a coke dry extinguishing system for charging red-hot coke extruded from a coke oven into a cooling tower.
In the charging method, the hoisting load for raising the red-hot coke to the charging port of the cooling tower can be reduced and the cost of the coke machine and the frame supporting it can be significantly reduced. The present invention provides a method for receiving and charging dry fire extinguishing equipment.

The present invention provides a method for charging IC red-hot coke cut from a coke oven into a cooling tower, in which the operational amount of red-hot coke charged into the cooling tower is divided into a plurality of parts, pushed out from the coke oven, and divided. The extruded red-hot coke is transferred to the above cooling tower multiple times using coke packets, and the coke is rolled up. - Smaller and lighter machine and frame. The aim is to achieve the above objectives.

A preferred embodiment of the method of the present invention will be described below in detail with reference to the attached drawings fJ.

Figure 2 shows a coke dry extinguishing system including a coke oven, illustrating the method of the present invention;
The figure is a schematic view taken along the line 1-111 in FIG. 2, and FIG. 1 is a perspective view of a coke packet used in carrying out the method of the present invention.

First, to explain this coke dry extinguishing installation J6, 2 in the figure is a coke oven, and this oven 2 is equipped with a number of ovens 3, each of which generates a predetermined amount of red-hot coke. ing. This red hot coke per kiln becomes the red hot coke operating charge.

A fire extinguisher rail 6 is installed between the coke oven 2 and the cooling tower 4, on which a fire extinguisher 5 for conveying red-hot coke runs.

The cooling tower 4 is surrounded by a frame 7, and a hoist 8 supported by the frame is provided on the upper part of the frame 7 so as to be movable laterally on rails 9.
This frame 7 is also provided with a hoisting tower 10 for carrying out the work of winding and rolling the packets, as will be described later.

On the other hand, the fire engine 5 includes a locomotive 11 that exerts driving force,
It is composed of a pair of packet wheels 12 and 13 that are attached to both sides (IJ) sandwiching this.

In the illustrated example, the hot engine car 11 is located at the center of the pair of bucket cars 1 to 12 and 13 and connected, but it is also possible to connect the packet cars and connect the locomotive 11 to one of them. You can do it like this.

In each of the packet cars 12 and 13, two coke packets 15 are arranged in parallel, each having an opening/closing door 14 formed in a horizontally long rectangular cross-section as shown in FIG. Placed on 1! It is designed to be used. Incidentally, it goes without saying that the opening/closing door 1/I is provided with a locking mechanism. The lower end of this coke packet 15 has 4
The wheels 16... are removed, and the movement of the packets 15 is regulated by checking the voltage of the wheels 16 with a packet stopper 17 provided on each bucket truck so that it can be lowered freely. (See Figure 3). The total amount of coke packets 15 placed in one bucket 1 to car (in the illustrated example, the amount equivalent to two packets) is the amount of coke transported at one time, that is, the red hot coke operation charge. corresponds to the amount.

Therefore, if the amount of coke per oven is about 28 tons, each coke packet 15 will be loaded with 1,1 ton of red-hot coke. Therefore, the capacity of one coke packet is approximately half that of the conventional example (see FIG. 1), and the weight is reduced accordingly.

6- On the other hand, as shown in FIGS. 2 and 3, the hoisting base 10
and the fire engine rail 6, there is a n
A lead-in rail 18 is laid with a slight inclination downward toward the winding base 10, and has a length on which a total of three coke packets 15 can be placed, as shown.

The retractable rail 18 has first and second storage spaces arranged at a predetermined interval along its length.
Packet stoppers 19 and 20 are provided. A slope is formed at the tips of these stoppers, and when raised, the wheels 16 of the packet 15 are pushed upward in the slope direction and locked, so that the adjacent buckets 1 are spaced a little apart by 1. It has become.

In addition, a rail 22 on which a retracting device 21 runs is laid in parallel with the retracting rail 18, and the bucket 1 is moved to the retracting rail 18-F while being pushed by an arm 23 extending from the retracting device 21, and is moved to an arbitrary position on the retracting rail 18-F. It is configured such that it can be stopped at any position.

Then, from the first bucket 1 to the stopper 19,
The configuration is such that the packet is set at the position , and the packet is set at the position of the second packet stopper 20 . Then, the packet at the position ■ is moved to the hoisting machine 8.

In the above device example, the red heat = 1-coke per oven is divided into two, but the number of coke packets can be further increased and the coke can be divided into three or more. Of course it's Monino.

Next, the method of the present invention will be explained based on the fire extinguishing equipment configured as described above.

As shown in FIG. 2, in the present invention, one of the coke ovens is
The operational charge of red hot coke extruded from one kiln (for example, about 28 tOn) is transferred to two coke packets 15a, 1
5b or coke packets 15d and 15c. In the illustrated example, the coke bucket 1 on the packet car 12 is shown receiving the coke by 15a and 15b, and the other buckets 1-1113 are empty. The packets 15c and 15d to be placed thereon are handled on the side of the fire tower 4.

First, red-hot coke in the oven 3 is pushed out by an extruder fJ 24 installed in parallel with the coke oven 2, and is deposited in coke packets 15a and 15b. For example, this operation
The extruder 24 pumps half of the red hot coke (approximately 14.
When the extruder 24 is extruded and loaded into one coke packet 15a, the extruder 24 is temporarily stopped, and then the locomotive 5 on the fire engine rail (3) is moved to load the other coke packet 15b into the kiln 3. Then, the extruder 24 is driven again to resume extrusion, and the remaining half of the red hot coke (approximately 14 tons) is transferred to the coke packet 15.
Spell it to be loaded onto b.

In this way, when the red hot coke is divided and pushed out and the kiln discharge work is completed, the locomotive 11 is driven and the fire extinguishing engine 5 is moved toward the winding L tower 1o of the coke extinguishing equipment.

Then, the empty packet car 13 with no packets on it is positioned at the lead-in rail 18, and the locomotive 11 is first stopped.

9- On the other hand, in the fire extinguishing equipment, as mentioned above, red-hot coke is being charged into the cooling tower 4 simultaneously while the kiln is being unloaded. The completed empty coke packets 15c and 15d are placed at the hoisting base 1.
They are waiting at positions ■ and ■ below 0 (see Figure 3).

Then, as described above, when the empty bucket l-it 13 is stopped at a location corresponding to the retracting rail 18, the empty coke buckets 1 to 15C, 15d are pushed by the retracting device 21 and placed onto the empty packet car 13. Load them one by one. Specifically, first, when the empty coke packet 15c located at position (3) is placed at position (2), the packet stopper 17 with the installed number on the packet car 13 is raised to lock it.

Next, the locomotive 11 is moved a little as much as possible to load another empty coke packet 15d, and the packet car 13 is stopped at the corresponding position.
Empty coke bucket moved from position to position ■
Press -15d further to move it to the position (■) to complete the loading of the empty coke packet. Next, work begins on pulling in packets loaded with red-hot coke. First, the locomotive 11 is moved a little further and the actual packet 1 containing red-hot coke is
5a and 15b are loaded on the bucket 1-car 12 and the hoisting tower 10
, that is, at the retracting rail 18.

Specifically, one of the actual packets is first positioned at the lead-in rail 18 (the position marked in FIG. 3). Next, when the stopper 17 that locks the packet 158 is lowered, the packet 15a equipped with wheels will move along the pull-in rail 18 since each packet car 12.13 is formed to be inclined in the direction of the pull-in rail 18. The packet moves from the position ■ to the position ■, and is stopped by the second packet stopper 20 provided on the retracting rail 18. This movement is performed while being controlled by the retraction device 21.

Next, the locomotive 11 is moved a little again and the other real packet 15i1 is stopped in correspondence with the pull-in rail 18 (position 1 in the figure). 'Then, the packet stopper 17 of this packet car 12 is lowered to release the actual packet 15b, and then the second packet stopper 20 of the retracting rail 18 is lowered, and while controlled by the retracting device 21, Real packets 15a and 15b loaded with red-hot coke are located at
Gradually move the TV and pull it in to the position marked ■.

Next, when the first bucket i to the soot brim 19 are made to have a soil texture, since the tip of this stopper 19 is sloped (
6 and pushes it diagonally upward, so that the buckets 1 to 1511 are slightly separated from the packet 15a at the IV position.

Then, the hoisting machine 8 hoists up the packet 15b at position (■) and raises it, and after charging the red hot coke therein into the fire extinguishing tower 4, the empty bucket ()-15h is lowered and again (■).
lower it to the position.

Next, after lowering one first packet stopper, the retracting device 21 is moved to move the real packet 15a at the IV position together with the empty packet 15b at the position ■, and move this real packet 15a to the position ■. I'll push you up to

Then, the first and second buckets [stopper 19°20
In order to lock each packet to these, the packets 15a located at ■ and ■ are raised as described above.
, 15b are each slightly separated.

Next, the real packet 15a is hoisted up and raised by the hoisting machine 8, red-hot coke is charged into the fire extinguishing tower 4, and then the empty packet 15#I is lowered to the position (3) again.

Then, empty packets 15b and 15a are filled with ■ and ■, respectively.
Wait at the position and then shoot some coke packets.
Wait for the empty packet car 12 that has not been filled to arrive again. still,
This time, packet car 13 will be loaded with red hot coke.

On the other hand, while the red hot coke charging operation is being carried out, the locomotive 5 loads empty coke packets 15c and 15d on the first packet car 13 connected thereto, and no coke is placed on the other packet cars 12. without putting a packet on it,
The coke is moved again to the coke oven side to be deposited, and the kiln unloading operation as described above is carried out simultaneously with the red hot coke 13-charging operation.

From then on, such operations are repeated one after another to carry out carcass receiving and charging operations.

In this way, the amount of coke per kiln, that is, the amount of red-hot coke charged during operation, is divided into multiple times (twice) and charged into the fire extinguishing tower 4. 6 of the hoisting load when charging in one time conventionally.
It can be reduced to 0-70%.

Therefore, in response to this reduced hoisting load, not only can the hoisting machine itself be made smaller by lowering its own hoisting capacity, but the strength of the frame 4 supporting the hoisting machine 8 can also be increased. It can be kept low according to the load, and the size of each member can be reduced in size and weight.

The locomotive 11 is equipped with two packet cars 12 and 13, front and rear, and when traveling from the coke oven to the winding tower, one of the packet cars is loaded with actual packets loaded with red hot coke, and vice versa. When heading from the coke oven to the coke oven, empty packets are loaded onto the other packet car, so that the work of unloading the red hot coke from the coke oven and charging the red hot coke into the cooling tower is done. can be performed simultaneously and in parallel, and therefore the time cycle can be significantly shortened, so that work efficiency can be improved.

In addition, in the method of the present invention, two packet cars are connected to a locomotive in order to shorten the time cycle, but the method is not limited to this, and only one packet car can be connected to a locomotive. Of course, it is also possible to operate with

In summary, the method of the present invention exhibits the following excellent effects.

(1) The red-hot coke per kiln is divided into parts and charged into the fire extinguishing tower, so the hoisting load of the hoisting machine is significantly reduced compared to the conventional case where the coke was charged in batches. be able to.

(2) Therefore, not only can the hoist itself be made smaller and lighter, but also the strength of each part of the frame that supports it can be lowered, and a significant stroke down can be achieved.
