Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a coke oven, and particularly to a red-hot coke receiving device in a coke oven that performs dry extinguishing of coke.

(Prior art) In coke dry extinguishing equipment, red-hot coke discharged from a 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 transported by a crane. The red-hot coke is hoisted up and carried onto 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, the coke bucket is effectively used to generate 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.

(Problem to be solved by the invention) The conventional coke bucket cart and bucket cart are
As shown in Figures a and 4b, a rectangular coke bucket 23 having a rectangular coke receiving plate 22 is mounted on a bucket truck 1, and a train 3 is carried to a coke oven 24.
It is towed by 1 and stopped at a fixed position at the coke oven kiln mouth before discharge from the kiln, and receives the coke 25 pushed out from the coke oven 24 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 26 is extremely close to the oven side, and due to the angle of repose 29 of the red-hot coke, the coke after being deposited is as shown in the packing diagrams in Figures 5a and 5b. As a result, the effective coke volume ratio to the total volume of the coke bucket 23 was extremely low.

In addition, as is clear from the packing diagram, the load is uneven and it is necessary to install a balance weight on the side opposite the coke oven of the coke bucket 23 in order to maintain balance when hoisting the coke bucket with a crane in the hoisting tower. There was an inconvenience that it became heavy.

To solve this problem, we equipped the coke bucket cart with a rotatable turntable.
A coke bucket trolley on which a coke bucket was placed on this turntable was developed in 1974.
It is disclosed in Publication No. 39483.

According to this technology, a square or circular coke bucket can be placed on the turntable and the turntable can be rotated to receive the cork bucket, making it possible to reduce the capacity of the coke bucket. It is explained that this will eliminate the trouble of falling.

However, since the coke bucket cart disclosed in Japanese Utility Model Publication No. 54-39483 is equipped with a turntable on top of the cart, falling debris and floating dust from the gap between the discharge gates that occur during unloading of the kiln are removed from the turntable. For this reason, when the coke bucket is placed on the turntable, the coke lumps or coke powder deposited on the turntable become a hindrance, impeding the stable placement of the coke bucket and the smooth rotation of the coke bucket. This is disadvantageous and requires manual or compressed air removal of the coke deposits.

Further, the conventional discharge gate opening/closing device has pins 20, 2 at the end of the discharge gate 10, as shown in FIG. 4b.
Since the opening/closing rods 21 and 21 are connected through the terminal 0 and the hanging fitting 27 is provided on the upper part of the opening/closing rods 21, 21, when the cork bucket cart 23 is to be rotated on the bucket truck, the discharge gate 10 and the hanging fitting 27 are connected. The opening/closing device composed of the metal fittings 27, pins 20, etc. has the maximum rotational dimension. That is, the turning radius was very large, which caused the problem that it interfered with surrounding buildings.

(Means for solving the problems) The present invention improves the disadvantages of the prior art,
It is an object of the present invention to provide a practical device that increases the coke effective volume ratio in the coke bucket and reduces the weight of the coke bucket when rotating the coke bucket.

That is, the present invention provides a red-hot coke receiving device in which a coke bucket having a cylindrical or polygonal body and a pair of discharge gates rotatable in opposite directions at the bottom is rotatably mounted on a bucket truck. , each of the pair of discharge gates is provided with a catching block at both ends of the discharge gate, and on the other hand, a beam is provided on the outer periphery of the coke bucket so as to surround the coke bucket, away from the coke bucket, and facing this beam.

A motor 17 and a power transmission mechanism 18 for rotating the rotating arm 19 are also provided.

When the coke bucket cart 2 according to the present invention is placed on the coke bucket cart 1, the rails 14, 14 are placed on the rollers 15, 15, . . . as described above, and the rotating arm 1 provided on the bucket truck 1
The protrusions 19A and 19B of 9 are the discharge gates 10 and 10.
are placed so as to fit into recesses 10A and 10B provided on the bottom surface of the holder, respectively.

Next, a mechanism for lifting the coke bucket cart 2 according to the present invention will be described.

In the present invention, the discharge gates 10, 10 include
Catching blocks 11, 11 are provided at both ends in a direction perpendicular to the opening/closing direction of the discharge gate.

On the other hand, a beam 8 is provided on the outer periphery of the coke bucket 2 so as to surround the coke bucket 2 apart from the coke bucket 2, and hanging fittings 3, 3 are fixedly installed on opposite sides of the beam 8. The catching block 1 is attached to each of these hanging fittings 3, 3.
A connecting rod 4 is provided which engages with 1. 7 in the diagram
is a roller provided at the lower end of the connecting rod 4, and this roller 7 is adapted to engage with the catching block. 6 is a pin for rotatably attaching the roller 7 to the connecting rod 4, 5 is a pin for attaching the connecting rod 4 to the beam 8, 13 is a guide rail fixed on the bucket cart, and 12 is a guide roller.

The present invention is constructed as described above, and in particular, by providing the connecting rod 4 on the side of the hanging fitting, the weight of the cork bucket bag 2 is reduced accordingly;
Since the connecting rod 4 is not rotated, the radius of rotation of the coke bucket 2 is reduced accordingly.

(Function) The operation of placing the coke bucket according to the present invention on a bucket cart, rotating the coke bucket on the bucket cart, and then lifting the coke bucket again will be described.

3a and 3b show the state in which the coke bucket 2 is lifted and suspended by the hanging fitting 3.

When hoisting the coke bucket cart 2 as shown in FIG. Rollers 7, 7, which are rotatably provided at 4 through pins 6, 6, respectively, catch catching blocks 11, 11 provided at the ends of the discharge gates 10, 10, and are lifted up as they are. Therefore, when placing the coke bucket cart 2 on the bucket cart 1, it is done by lowering the hanging fitting 2 in this state.

While the hanging fitting 2 is being lowered, a guide roller 12 installed at the rear of the hanging fitting 2 is guided by a guide 13 fixed on the bucket cart 1, and positioning is performed. If you continue to lower the hanging fitting 2 in this state, the bottom of the coke bucket 2, that is, the discharge gate 1
0 and 10 are placed on the bucket truck. In other words,
As shown in FIGS. 1 and 2, a discharge gate 10,
Semicircular rails 14, 14 provided on the outer bottom surface of 10
are put together to form a circular ring and placed on rollers 15, 15, . . . on a bucket truck. When the hanging fitting 3 is further lowered in this state, the roller 7 provided at the lower end of the connecting rod 4 comes off from the catching block 11 as shown in FIG. 3b, and the caulk bucket 2 is disengaged from the hanging fitting 3. It becomes rotatable. The hanging fitting 3 completes its descent with its lower end surface in contact with a pedestal 30 provided on the bucket cart 1 and enters a standby state.

When the coke bucket cart 2 placed on the plurality of rollers 15, 15, . Since the coke bucket 2 is rotated by driving the motor 17, red hot coke is received. It is effective to set the rotation of the coke bucket 2 in the range of 3 to 15 rpm, preferably 5 to 10 rpm. If this rotation is less than 3 rpm, the amount of red-hot coke in the coke bucket will not be uniform in the circumferential direction, and even if high-speed rotation exceeds 15 rpm, the effect of uniform coke in the circumferential direction will reach a ceiling, and the energy required for rotation will be This is not desirable because it wastes money. When this rotation is in the range of 5 to 10 rpm, in addition to the effect of uniformizing the amount in the circumferential direction, it is also possible to equalize the particle size distribution in the circumferential direction of the red hot coke charged into the coke bucket. This has the effect of making the air volume distribution uniform in the circumferential direction after being charged into the pre-chamber of the fire extinguishing equipment. The rotational speed of this coke bucket is not limited to the device of the present invention, but can be applied to a receiving device for transporting red-hot coke to a dry fire extinguishing facility, such as Utility Model Application No. 1166-1980, Utility Model Application No. 59-81779, Utility Model Application No. 59-81. -81780, the invention of the same name filed on August 17, 1980, etc., can be widely applied to devices related to the inventions and ideas of the present inventor.

The red-hot coke thus disposed of is transported to the dry fire extinguishing equipment by running the bucket truck 1, and then lifted up. The lifting of the coke bucket cart 2 can be carried out by the reverse operation of the above-described lifting of the coke bucket cart 2.

After the coke bucket 2 has been lifted above the dry fire extinguishing equipment, when charging red hot coke into the chamber, the lifting fitting 3 is lowered with the bottom of the coke bucket 2 other than the discharge gates 10 and 10 resting on the frame. As a result, the discharge gate is rotated via the pin 9 to discharge the red-hot coke into the chamber.

(Effects of the Invention) As described above, according to the present invention, when dumping red-hot coke, in a device for dumping red-hot coke while rotating the coke bucket, a part of the device for lifting the coke bucket is provided on the beam. Since the weight of the coke bucket is reduced, the power required for receiving the carcass, lifting and hanging it can be reduced accordingly, and the radius of rotation when rotating the coke bucket can be reduced, simplifying the equipment. In addition, it is possible to simplify the layout within the travel range of the bucket truck.
