Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a coke oven, particularly a red-hot coke receiving device in a coke oven that performs dry extinguishing of coke.

(Prior art) In coke dry extinguishing equipment, the red-hot coke discharged from the coke oven is received by a coke bucket placed on a bucket truck running on rails and transported to a hoisting tower by the bucket truck, and then the coke bucket is hoisted by a crane. The red-hot coke is then transferred to the pre-chamber of the dry extinguishing equipment, the coke discharge gate installed at the bottom of the coke bucket is opened, and the red-hot coke is charged into the pre-chamber. For example, it is effectively used to obtain steam for power generation in a boiler, but after the red-hot coke has been discharged, the coke bucket is placed on the bucket truck again to prepare for the next kiln discharge from the coke oven.

Thus, the coke bucket is a conveying device that is repeatedly used together with the bucket cart for conveying red hot coke.

The conventional coke bucket cart and bucket cart are the 7th
As shown in Figure A and Figure 7B, a rectangular coke bucket 3 with a rectangular coke receiving plate 2 is mounted on a bucket truck 1, and the truck is pulled by a train 5 to a coke oven 4 and placed at the mouth of the coke oven before being discharged from the kiln. It stops at a fixed position and collects the coke 7 pushed out from the coke oven 4 via the coke guide while traveling at low speed within the range of the effective length l of the bucket. However, in the existing coke oven, the coke falling point 8 is extremely close to the oven side, and due to the angle of repose of the red-hot coke, the coke after being crushed is shifted toward the oven side as shown in Figure 8 A and Figure 8 B. Tired coke bucket 3
The ratio of coke effective volume to total volume was extremely low.

Also, as is clear from the packing diagram, it is necessary to install a balance weight on the side opposite the coke oven of the coke bucket 3 in order to balance the load when lifting it with a crane in the hoisting tower. There was an inconvenience that it became heavy.

(Problems to be Solved by the Invention) An object of the present invention is to provide a receiving device for improving the disadvantages of the prior art and increasing the effective coke volume ratio in the coke bucket.

Another purpose of the present invention is to reduce the weight of the coke bucket, and a further purpose is to charge the red hot coke into the chamber evenly in the circumferential direction when discharging the red hot coke from the coke bucket. .

(Means and effects for solving the problem) The present invention has a cylindrical body and a coke bucket with a discharge gate at the bottom, and trunnions are fixed at opposite positions on the outside of the coke bucket, and the coke bucket is mounted on a revolving body. The revolving body is connected to a drive device so as to be rotatable, and is placed on a bucket truck.
A steel frame is provided on the outer periphery of the cork bucket body so that it can move up and down, surrounding the cork bucket, and hanging fittings are fixed at opposing positions on this steel frame, and each hanging fitting is engaged with the trunnion. This is a red-hot coke receiving device characterized by being provided with a block that

The present invention will be explained in detail below with reference to an embodiment shown in the drawings.

FIGS. 1A and 1B are a front view and a side view showing an embodiment of the present invention.

The cork bucket 3 according to the present invention has a cylindrical body as shown in FIGS. 1A and 1B, preferably with an upper end expanded obliquely upward, and an inner liner attached thereto. It has a discharge gate 11 at its bottom.

On the other hand, the bucket cart 1 has a steel frame 13 equipped with a traveling device, a revolving body 14 installed on the steel frame, a drive device 15 for rotating it, and a hanging bracket support stand 16 attached to the steel frame. It is configured.

When red-hot coke is dumped using the device according to the present invention configured as described above, the bucket cart is stopped in a fixed position, and the cylindrical coke bucket mounted on the revolving structure is rotated by the revolving structure to collect the coke. It receives the coke extruded from the furnace. Figure 2 shows the coke loading diagram after being dumped.

As shown in Figure 2, the ratio of effective coke volume to the total volume of the bucket has been significantly increased, and when compared with the conventional rectangular coke bucket that carries the same volume of coke, the coke bucket according to the present invention can be made lighter. can.

Furthermore, as is clear from FIG. 2, there is no unbalanced load, no balance weight is required, and the weight of the coke bucket can be reduced. 9 in the figure indicates the angle of repose.

The mechanism for lifting and lowering the coke bucket by a crane and for opening and closing the discharge gate 11 is the same as the structure of a conventional coke bucket, but on the revolving body 14,
If you try to swivel the suspension including the guide roller device, the radius of rotation will become large and there is a good chance of interference with the foundation structure and each device, so below is an example of swiveling only the cork bucket main body and the gate. I will explain.

The discharge gate 11 shown in FIGS. 3A and 3B includes a trunnion 17 and a connecting rod mounting bracket 18.
Ring-shaped frame 19 with attached, connecting rod 2
0. It is composed of an opening/closing gate 21 and a gate hinge 22 jointed with the opening/closing gate 21. The hanging fitting 12 is completely separated from the coke bucket 3, and as shown in FIG.
As shown in Figures A and B, the crane hanger 24
It has a structure integrated by a ring-shaped steel frame 25.

The bucket is suspended, the lower surface of the discharge gate 11 is grounded on the revolving body 14 of the bucket truck, and only the hanging bracket 12 is lowered, and the hanging bracket 12 is attached to the steel frame of the bucket truck. It is entrusted to the 16th.

In this state, the ring-shaped frame 19 of the discharge gate 11 is supported by the opening/closing connecting rod 20, and is attached to the trunnion 17 and the hanging bracket as shown in FIGS. The blocks 23 are completely separated with a gap a created in the higher direction. Yotsutte coke bucket 3 and discharge gate 11
can be rotated.

After the turning support is completed, the bucket truck travels to the hoisting tower and stops. When the hanging fixture 12 is lifted by a crane, a block 23 provided on the hanging fixture catches the trunnion 17 of the discharge gate 11, and the coke bucket 3 is suspended via the connecting rod 20 of the discharge gate 11 and the opening/closing gate 21. To open and close the gate on the chamber, place the coke bucket 3 on the fulcrum on the chamber, and lower the crane to lower the trunnion 17 due to the gate's own weight and the weight of red-hot coke, opening and closing the gate 2.
