Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for efficiently transporting compacted coal from a compression molding machine to a coke oven using a plurality of transport cases.

Concerning the transportation of compacted coal, it is a new technical field and there are few examples of conventional technology, but there is a concept as shown in FIG. Briefly, the block-shaped compression molded coal 2 produced by the compression molding machine 1 is loaded onto the charging trolley 4, which has been moved to the outlet of the compression molding machine 1 together with the bottom plate 3, using a conveyor 5 or the like. The charging trolley 4 is moved along the rails 6 in a direction perpendicular to the plane of the paper to the coke oven 7, where the conveyor 5 is operated again and the compacted coal 2 is charged into the coke oven 7.

After charging this compression molding coal 2, the Bisoujinki trolley 4 returns to the compression molding machine 1 in an empty state to receive the next compression molding coal 2, and the above-mentioned operation is repeated to sequentially produce a large number of blocks. The compacted coal 2 is charged into a coke oven 7. In the coke oven 7, the compacted coal 2 is carbonized to produce coke, which is used as an auxiliary raw material in a blast furnace or the like.

The transportation of such compression molded coal between the compression molding machine and the coke oven is carried out by a charging trolley that reciprocates on rails laid in a small space secured beside the coke oven, as described above.

In this case, the total time required for loading the compacted coal into the charging truck, the round trip time for the charging truck from the loading location to the coke oven, and the time required for charging is the total time required for the series of conveyance and charging system. Become.

In the case of the transport method shown in Fig. 1, the distance traveled by the compressed briquettes during loading from the compression molding machine 1 to the charging trolley 4 is relatively long, and the compression briquettes may partially separate or fall off during transportation. Since the conveyance speed is limited in order to prevent this, it takes a lot of time to convey, so sufficient measures to protect the conveyance are required.

Furthermore, although compacted coal has sufficient robustness for transportation and charging, if cracks occur or grow during transportation, resulting in partial separation or falling off, it is necessary to dispose of the This requires a great deal of time and effort, and results in a significant disruption to the time cycle for charging compacted coal into a coke oven.

The present invention solves the above-mentioned problems, prevents the compression briquettes from being partially separated and falling off, and if compression briquettes unsuitable for charging occur, they can be quickly disposed of. The purpose of the present invention is to provide a new method and device for transporting compacted coal.

The feature is that multiple compressed briquette transport cases are free-standing and can be moved horizontally and vertically in the vicinity of the briquette outlet of the compression molding machine, allowing them to be exchanged horizontally. The cases are transported by a refilling trolley that runs on rails installed along the coke oven, and the empty transport cases, which have been charged with compacted coal into the coke oven, are transported by this charging trolley. The method of transporting the compressed briquettes is to transport the charcoal back to the vicinity of the compression molding machine, and in addition, means for moving the compression charcoal transport case horizontally and vertically is provided near the briquette outlet of the compression molding machine. A device is provided with a transfer stand on the top surface, and has means for moving the conveyance case horizontally and vertically in order to travel between the relay stand and the coke oven and to deliver the compacted coal between the relay stand and the coke oven. This is a compressed and formed coal conveying device equipped with a loading cart.

Hereinafter, the present invention will be explained in detail based on examples thereof.

FIG. 2 is a plan view of the compression molded coal conveying device 10 that transports the block-shaped compression molded coal 2 to the coke oven 7. FIG.

In the vicinity of the outlet 11 for the compression molded coal 2 of the compression molding machine 1, a moving means 13 for horizontal and vertical movement of the molded coal transport case 12 is provided.
A relay stand 14 having a
A charging trolley 16 is provided which has a transport case moving means 15 for traveling between the transfer stand 14 and the coke oven 7 and delivering the compacted coal 2 between the transfer stand 14 and the coke oven 7. The moving means 13 and 15 are, for example, the transverse rollers 17 and the vertical rollers 18 of the molded coal conveyance teeth 12, and are used to move the conveyance case 12 in a plane. In addition, when this conveyance case 12 is provided with wheels or the like on its lower surface, rails (guide tracks) or the like may be provided in place of the rollers 1, 7, 18.

The relay table 14 allows a plurality of conveyance cases 12 to be freely replaced by moving them in a free-standing manner in the vicinity of the coal molding outlet 11 of the compression molding machine 1, and its planar shape is shown in FIG. Even if it is L-shaped, it may be rectangular or 7-shaped as shown in the embodiments described later.
In short, the conveyance case 12 receives the compression molded coal 2 from the compression molding machine 1.
It is only necessary to provide a space that can receive the empty transport case 12 and replace the empty transport case 12 two-dimensionally without interfering with the empty transport case 12, and a moving means 13 for that purpose. Note that a pusher 19 is attached to move the transport case 12 as necessary.

The charging machine trolley 16 has a space for mounting the transport case 12, and also has a driver's cab 2 for commanding movement on the rails 6 provided along the coke oven 7.
1. Drive means such as a charging machine 22 for charging the compression molded coal 2 into the coke oven 7 and an opening/closing machine 23 for opening and closing the doors of each charging port of the coke oven 7, and their control means are installed. .

Note that the rails 6 on which the charging machine truck 16 runs are conventionally laid for the extruder 24 that extrudes coke in which the compressed coal 2 has been carbonized from the coke oven 7; If the charging machine truck 16 is moved to each charging port of the coke oven 7, there is no need to newly lay the rails 6, and when the conveying device 10 of the present invention is introduced into a conventional coke oven plant. can also be done very easily.

The transport case 12 stores the compressed coal 2 and prevents it from being partially separated or falling off, and also transports the charging machine trolley 1 at any time.
6 to transport the compressed and formed coal 2. In principle, this is just a container without any power drive source, and the charging machine truck 16 is equipped with power equipment.
As a result, there is an advantage that any number can be adopted depending on the operating conditions of the coke oven 7 and the compression molding machine 1. Therefore, only one charging machine trolley 16 is required, which runs on one rail, and the transfer case 12 can be conveniently moved (if replaced, the compression molded coal 2 can be transferred one after another) on the transfer stand 14, which is tilted by 1 degree. I can do it.

Although this conveyance case 12 is not shown, the compressed briquette 2
An inner frame is used to store the coking coal to prevent partial separation or falling off, and even if this occurs, the coking coal will not leak out, and an outer frame to store the inner frame and maintain its self-supporting state By using a frame body, even if a problem arises that makes it inappropriate to charge the compacted coal 2 into the coke oven 7, the subsequent compaction can be carried out by separately removing only the transport case 12. It is possible to avoid hindering the conveyance of the briquette charcoal 2. As a result, there is an advantage that the operation of the charging machine truck 16 and the operation of the coke oven 7 can be avoided.

According to the configuration of the above embodiment, the compression molded coal 2 can be frequently transported from the compression molding machine 1 to the coke oven 7 using a plurality of transport cases 12 as described below.

First, one of the plurality of transport cases 12 in a freestanding state
As shown in FIG. 3(a), two empty cases 12a are placed on the transfer stand 14 in front of the outlet 11 of the compression molding machine 1, and the other empty case 12b is placed in the charging machine adjacent to the transfer stand 14. Trolley 1

In this state, as shown in FIG.
Insert into a. Then, if necessary, the compressed coal 2 is cut by a cutting machine 20 provided on the transfer table 14 or the compression molding machine 1, and the compressed molded coal 2 is stored in the transport case 12a. While this work is being carried out, the case 12b on the charging machine cart 16 is moved in the direction of arrow 26 via the moving means 15 by a pusher (not shown) or the like.

When the case 12b is completely placed on the transfer stand 14 as shown in FIG.
to move in the direction of arrow 27.

At this time, the case 12a is attached to the relay stand 1 as shown in FIG.
4 and on the charging machine trolley 16 via the transverse rollers 17 and longitudinal rollers 18 of the moving means 13.15 on the charging machine trolley 16. During this time, the case 12b on the relay stand 14 is transferred as shown by the arrow 28 (Fig. 3(c)).
), and reaches in front of the outlet 11 of the compression molding machine 1. While the next compressed coal 2 is being inserted into this case 12b,
As shown in FIG. 3(d), the charging gutter truck 16 runs on the rails 6. When the predetermined charging port of the coke oven 7 is reached, the opening/closing machine 23 mounted on the charging gutter truck 16 opens the charging port of the coke oven 7 and the case 1 is opened as shown in the sixth example.
A charging machine 22 behind 2a charges only the compacted coal 2 in the case 12a into the coke oven 7. The case 12a emptied in this manner is transported toward the relay stand 14 by the loading gutter truck 16. When the state shown in FIG. 3(a) is returned, the above-described operations are repeated, and a large number of compacted coals 2 are sequentially charged into the coke oven 7.

During such work, if the compacted coal 2 in the transport case 12 becomes unsuitable for charging into the coke oven due to the occurrence or progression of cracks, the transport case 12 should be moved immediately. can be stopped and removed from the transport device 10 using a separately provided crane, pusher, or the like. Therefore, the movement and conveyance of subsequent conveyance cases are not hindered and the operation of the plant is not interrupted, and the compression-molded coal that has been improperly charged can be subjected to molding again.

Note that the number of transport cases 12 used is not limited to two as described above, but three or more may be used as shown in FIG. 7 if a large space can be taken up for the relay stand 14. can. In this case, the movement of the transport case 12 on the relay stand 14 and the charging gutter truck 16 is as shown in FIG.
(b) It will be easier to understand.

Also, whether the relay stand 14 is a planar type as shown in FIG.
．． It may be in the shape of a letter. In this case, each transport case 12a
, 12b, respectively, as indicated by arrows 29, 30, and 31, the replacement can be performed.

The above-mentioned transport case 12 is for storing and transporting compressed coal having the length of one charging port of a coke oven.
As shown in the figure, a plurality of small transport cases 32 for storing and transporting the divided compressed and formed coal may be used. In this case, the transport case 32a containing the compressed and molded coal 2 is shown at the arrow mark 33.
The empty transport cases 32b are moved along the route indicated by the arrow 34 without interfering with each other. Depending on the operating conditions of the compression molding machine 1, three or more transport cases 32 may be used.

According to such transportation, the relay stand 14 can occupy a smaller space than the above-described embodiment.

In the above operation, since the transport case is made independent of the charging gutter truck and has a self-supporting structure, the necessary number of transport cases can be appropriately employed. Further, since the compacting operation of the compacted coal and the charging operation into the coke oven can be performed independently, each operation can be performed efficiently without being restricted by other operations. In addition, since the relay stand, transport case, etc. of the above-mentioned shape can be adopted as appropriate in consideration of the site of the coke oven plant, it can be easily introduced into an existing plant.

As described in detail above, the present invention is designed to operate a plurality of compression molded coal transport cases in a self-supporting state in transporting compressed molded coal in the form of a block formed by a coking coal compression molding machine to a coke oven. The compacted coal is moved horizontally near the compacted coal outlet of the compression molding machine so that it can be exchanged horizontally, and the transport case containing the compressed compacted coal is transported by a charging gutter truck that runs on rails installed along the coke oven. At the same time, there is provided a method for transporting compression molded coal, in which a coke oven is charged with compression molded coal and an empty transport case is transported again to the vicinity of the compression molding machine using this charging gutter truck; In a compression briquette trip device that transports compressed briquette coal into a coke oven in the form of a block, a means for moving the compression briquette transport case horizontally and vertically is installed near the briquette outlet of the compression molding machine. In addition to providing a transfer stand having a top surface, the conveyor case is provided with means for moving the conveyance case horizontally and vertically in order to travel between the transfer stand and the coke oven and to deliver the compressed briquette coal between the transfer stand and the coke oven. The compression molded coal transport device is equipped with a charging gutter truck, making it possible to shorten the time from production of compression molded coal to charging it into a coke oven, increasing production efficiency, and reducing the amount of compression molded coal being transported. This has the effect of preventing partial separation and agglomeration of coal, and even if compacted coal unsuitable for charging is generated, it can be disposed of quickly.
