Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a conveying device for compression molded coal for a coke oven, and more specifically, it uses a plurality of transport cases to efficiently transfer compression molded coal from a compression molding machine to a coke oven. It relates to a device for transporting.

This is used in the technical field of manufacturing coke using block-shaped compacted coal.

[Prior art]

The transportation technology for compressed briquette coal is a new field, and there are few examples of conventional technology, but there is a concept as shown in Fig. 5. Briefly, the block-shaped compression molded coal 2 produced by the compression molding machine 1 is loaded onto the loading machine truck 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 machine truck 4 is conveyed along the rails 6 in a direction perpendicular to the plane of the paper to a coke oven 7, where the conveyor 5 is operated again to charge the compressed coal 2 into the coke oven 7. This compressed charcoal 2
After charging, the charging machine truck 4 returns empty to the compression molding machine 1 to receive the next compression molded coal 2, and the above-mentioned operation is repeated to sequentially produce a large number of blocks of compression molded coal. 2 is charged into the coke oven 7. In the coke oven 7, the compacted coal 2 is carbonized to produce coke, which is used as blast furnace coke.

The compression molded coal was transported between the compression molding machine and the coke oven in a small space secured next to the coke oven as described above]1'1
This is done using a loading machine truck that moves back and forth on rails. In this case, the total time required for loading the compacted coal into the charging machine truck, the round trip time of the charging machine truck from the loading location to each opening of the coke oven, and the time required for charging The required time.

According to the conveying device shown in FIG. 5, the moving distance of the compressed briquettes when loading from the compression molding machine 1 to the charging machine trolley 4 is relatively long, and the compression briquettes have sufficient space for transportation and charging. Although it is robust, the movement speed is limited in order to prevent the compacted coal from partially separating or falling off, and it takes a lot of time to transport it to the coke oven. In addition, if cracks occur or grow during transportation, resulting in partial separation or falling off, it will take a lot of time and effort to deal with it, and the time cycle for charging the compacted coal into the coke oven will be delayed. This results in a significant impediment to the shortening of the period.

To improve this, a proposal was made in JP-A No. 59-108083 in which a charging machine truck running parallel to the coke oven accommodates the block-shaped briquettes in a transport case and transports them. There is. In this case, the briquettes are alternately transported in two transport cases, and these transport cases are interchangeable in a plane. For this purpose, a relay stand is installed near the molding machine, and the top surface thereof is equipped with a moving means for moving the transport case. However, this relay stand requires a large area, and there is a problem in that the transfer of transport cases between the charging machine truck and the relay stand and the exchange route of the transport cases on the relay stand are complicated and time consuming. .

The relay stand 12 may be of a stationary type as described above, but if it is of the type of a trolley and can be moved freely, it can be used either in the case where another coke oven 7 is installed across the compression molding machine 1, etc. When a failure occurs in one of the charging/extruding carts 15, the relay stand 12 is moved and the other charging/extruding cart 15 is moved.
There is an advantage that it can be used.

According to the embodiment configured as described above, the compression molded coal 2 can be frequently transported from the compression molding machine 1 to the coke oven 7 using the two transport cases IIA and IIB as described below.

As shown in FIG. 2(a), in the conveyance device 10,
) The transport case IIA is mounted on the fixed position on the upper surface 12a of the transfer stand 12, and the traversing cart 18, on which the empty transport case IIB is mounted on the upper surface 18a, travels in the direction of the arrow 16, and the compression molded ta1 and the coke are Evacuate between the furnaces 7. Therefore, when the charging/extruding table=X15 moves forward, the relay table 12 and the charging/extruding cart 15 become adjacent to each other. Transport case I
IA is the endless briquette coal that is compression molded in a compression molding machine 1 and extruded from the briquette outlet IA as shown in Figure 1(b).
The charcoal is accommodated through the bottom plate 3 shown in , and the accommodating process ends when one block-shaped compacted charcoal 2 is formed by the cutter IB. TA feeding case IIA with built-in compressed coal 2
is vertically moved in the direction of the arrow 13 via the moving means 20, and is transferred from the transfer stand 12 to the position shown by the broken line on the charging/extrusion truck 15.

Next, as shown in FIG. 2(b), the charging/pushing cart 15 runs on the rails 19A in the direction of the arrow 13 in order to charge the compressed coal 2 into the coke oven 7, and for example, The furnace stops at position 7a, and the furnace lid opening/closing machine 22 opens the furnace gate 7a. Then, the compression molded coal 2 accommodated in the transport case IIA is charged into the furnace chamber 7A by the charging machine 23. Note that, during or before or after this charging operation, for example, coke in the furnace chamber 7C is extruded using the extruder 24 as necessary. While the charging/extrusion truck I5 travels in the direction of the arrow I3 and charges the compacted coal 2, the traversing truck 18
traverses in the direction of arrow 17 and stops at a position adjacent to relay table 12, and the empty transport case IIB on board
As described above, the briquettes are moved vertically in the direction of arrow I4 via the moving means 20, and transferred to the transfer stand 12 to accommodate newly produced briquette coal.

After charging is completed, the charging/extruding cart 15 is an empty transport case 11
When A is loaded and returned by traveling in the direction of arrow 14, the second
As shown in Figure (c), it stops adjacent to the traversing truck 18,
The transport case IIA is transferred to the traversing trolley 18 via the moving means 20.
It is transferred to the position shown by the broken line on the upper surface 18a of the . As shown in FIG. 2(d), the traversing truck 18 is empty
When loaded and traversed in the direction of arrow 16, the loading/extruding cart 15 travels in the direction of arrow 14 and stops at the position shown by the two-dot chain line adjacent to the relay table 12, as shown in FIG. 2(a). Return to state. In this way, the positions of the transport cases 11A and 11B are exchanged, and this cycle is repeated so that the compacted coal 2 is sequentially charged into the coke oven 7 by the two transport cases IIA and IIB without any time loss. In addition, relay stand 12
can be made much smaller than in the case of the prior art, so the overall size of the transport device 10 can be reduced, and the movement route of the transport case can be simplified and replaced in a two-dimensional manner. Wear.

FIG. 3(a) shows an embodiment of the second invention, in which case transport carts 31A and 31B which are integral with or detachable from the transport cases IIA and IIB used in the first invention are employed. . The difference is that these have a function that replaces the traversing cart 18 and the relay stand 12 in the above-described invention. That is, in this example of the transport device 30, in order to transport the molded coal produced by the compression molding machine 1 to the coke oven 7, two transport cases IIA and IIB that accommodate the compression molded coal 2 via the bottom plate 3 are mounted on a trolley. Together, they form case transport carts 31A and 31B. These case transport carts 31A and 31B are able to move horizontally and vertically in the directions of arrows 33.34 and 35.36 on rails 32A and 32B laid near the briquette outlet IA of the compression molding machine 1. , when it moves in the direction of arrow 33, it can be evacuated between the compression molding machine 1 and the coke oven 70. In addition, as shown in FIG. 3(b) and (C),
An appropriate number of wheels 3 are installed at the bottom of the case transport carts 31A and 31B.
1C and 31d are installed, and for example, the trolleys 31A and 31B are temporarily attached to the rails 32A and 32B between their wheels.
A jack (not shown) is provided that can lift the
Individual wheels 3 are installed so that the direction of travel can be changed from horizontal to vertical or vice versa.
1C131d is designed to rotate 90 degrees. As shown in FIG. 3(a), the charging/extruding truck 38 connects either one of the case transport trucks 31A, 31B described above via a connecting mechanism 37, and connects the briquette outlet IA to the coke oven 7. The compacted coal 2 can be charged into the coke oven 7 by traveling between the coke ovens 7 and 7. therefore,
No rails are laid on the upper surface 38a of this charging/extruding cart 38, and instead of a space for mounting the transport case 11, a storage space for the case transport carts 31A and 31B is secured on the side of the charging machine 23. ing.

According to such an embodiment, two case transport trolleys 31
Compression molding charcoal 2 is frequently compression molded using A, 31B.
It can be transported to the coke oven 7 from a1.

As shown in FIG. 4(a), in the conveyance device 30, the conveyance case 11A integrated with the upper surface 31a of the case conveyance trolley 31A is located at the molded coal outlet IA of the compression molding machine l, and the conveyance case IIB travels on the rail 32A in the direction of the arrow 33 and is retracted between the compression molding machine 1 and the coke oven 7. Accordingly, the loading/extruding cart 38 can be adjacent to the case transporting cart 31A and is therefore connected to the case transporting cart 31A via the coupling mechanism 37. As in the case of the invention described above, when the conveyance case IIA finishes housing the briquette coal, the compressed briquette coal 2 is charged into the coke oven 7! 1111
In order to
Drive in the direction. As shown in FIG. 4(b), the charging/pushing cart 38 stops at the charging position, and the compressed coal 2 accommodated in the transport case IIA is charged into the furnace chamber 7A of the coke oven 7. . Meanwhile, the empty transport case 11B is moving along the rail 32A along the arrow 34 with its case transport trolley 31B.
When it reaches a position orthogonal to the rail 32B, use a jack (not shown) to place the wheels 31d of the case transport trolley 31B on the rail 32B and move it in the direction of the arrow 36 as shown in FIG. 4(C). The machine travels vertically, stops at the briquette outlet IA, and begins receiving briquettes from the compression molding machine 1. On the other hand, the empty case transport truck 31A, which has finished charging the compacted coal 2, returns along with the charging/extrusion truck 38 in the direction of the arrow 36.

As shown in FIG. 4(d), when the empty transport case 11A reaches the position of the rail 32A, the coupling mechanism 37 is released and the wheels 32c are placed on the rail 32A so that it can move laterally. Then, as shown in FIG. 4(e), the case transport trolley 31A is laterally retracted in the direction of the arrow 33. on the other hand,
If only the loading/extruding cart 38 is moved longitudinally in the direction of the arrow 36 and the case transporting cart 31B is connected via the coupling mechanism 37, the state shown in FIG. 4(a) is returned. By repeating this cycle, the compressed coal 2 can be charged into the coke oven 7 with less time loss.

〔Effect of the invention〕

As described above in detail using the embodiments, the first invention uses two transport cases that sequentially accommodate compressed briquettes, and also includes a relay stand near the briquette outlet of the compression molding machine, and a compression molding machine. A charging/extruding truck for charging charcoal into a coke oven, and a transverse truck that runs perpendicular to the running direction of the charging/extruding truck are provided. Since a moving means for vertically moving the transport case is installed, the compacted coal can be transported and charged into the coke oven with less time loss. Moreover,
While the transport case is transporting the compression molded coal and before returning after charging, one IB transport case accommodates the molded coal formed by the compression molding machine, and the production of compression molded coal is continued.
It is possible to shorten the time required for a series of transportation and charging operations from manufacturing to loading blocks.

In addition, the relay table occupies a small area, making the entire transport device compact and inexpensive, and the two transport cases have a flat movement path that allows them to be easily replaced, improving operability. improves. Furthermore, the compressed briquette coal is housed inside the transport case via the bottom plate, and the transport case functions as a protective case to prevent the compressed charcoal from deforming or cracking during transport and charging. It becomes possible to increase the speed and speed up the conveyance. Moreover, it can be applied not only to newly installed coke ovens but also to existing top-charge type coke ovens by making modifications such as installing rails for traversing carts.

In the second invention, instead of the two transport cases of the first invention, a case transport cart in which each transport case is integrated or detachable is used in place of the relay stand or the transverse cart. Reprinting time is no longer required, further reducing time loss.
