The present invention relates to a rotary gate device for a fire truck, and more particularly, to a rotary gate device for a fire truck in which coke discharge is controlled.

Typically, coke oven equipment used in steel mills is equipped with a plurality of carbonization chambers for charging coal to produce a hot coke by applying a high temperature heat for a certain time. In the process of producing coke, coal is dried through carbonization in the upper part of the carbonization chamber, and the glowing coke, which has been completed, is loaded into the fire truck by opening the coke oven door installed at the front and rear of the furnace and pushing it with an extruder.

By the way, since the red coke temperature is a high temperature (about 1, 000 ℃), if left as it is, the fire will continue to occur and the coke burns so that it does not function as a heat source, it has to digest the red coke. For this reason, the glowing coke after dry distillation in the coke oven is loaded into a fire truck 2 (Quenching Car) as shown in FIG.

2 to 6 will be described the operation of the rotary gate device of the fire truck (2) according to an embodiment of the present invention.

First, the drive unit 12 is operated to discharge the coke 4 loaded on the fire truck 2 to the warp 3. Then, the arm 16 connected to the rod 12a of the drive unit 12 is advanced in a straight line shape. As the arm 16 moves, the driving roller 9 coupled to the end of the arm 16 is moved diagonally along the inclined surface of the first groove 14a of the speed regulating plate 14. Subsequently, the drive roller 9 arriving at the second groove 14b is moved forward in a straight direction. When the driving roller 9 reaches the third groove 14c, the driving roller 9 again moves in an oblique direction.

The driving roller 9 moves in the diagonal direction, the linear direction and the diagonal direction as described above. Assuming that the speed of the driving roller 9 in the linear direction is 100%, the driving roller 9 moves in the diagonal direction. It is about 50%. For example, when the drive roller 9 passes the first groove 14a, the gate 5 is opened slowly, and the coke 4 is discharged. When the driving roller 9 moves the second groove 14b, the coke 4 is discharged by opening the gate 5 about 50% faster than when passing through the first groove 14a. When the driving roller 9 passes the third groove 14c, the gate 5 opens slowly compared with when passing the second groove 14b, and the coke 4 is discharged.

For the same reason as described above, the rack gear 20 that receives power operates the pinion gear 21 at the same speed ratio, and the pinion gear 21 and the gate 5 connected to the rotating shaft rotate at the same speed ratio.

When the driving roller 9 receives power from the driving unit 12 and operates inside the speed control plate 14, the gate 5 starts rotating around the rotating shaft and the coke 4 is discharged. At this time, the coke 4 discharge is controlled by the opening angle of the gate 5. If the gate 5 is fully opened vertically, the coke 4 has a large amount of discharge, so the rotational speed of the gate 5 is increased to operate in the closing direction, thereby controlling the amount of discharge.

Referring to FIG. 6, when the coke 4 loaded on the fire truck 2 is discharged from the arc plate 23 side, the difference between the angle and the direction in which it is discharged and discharged is delayed than the side without the arc plate 23. It can be seen that.

As described above, the rotary gate device of the fire truck according to the present invention can be loaded thinly and uniformly in a large area of the warp when discharging the coke to the warp, so that a complete fire extinguishing operation with a small amount of digestive water is required when extinguishing the coke residue. Can be.

In addition, the quality of the coke can be prevented from rising and the strength can be prevented from dropping.

In addition, the coke can be transported a certain amount during the transport operation and there is an effect that can prevent the burnout and damage of the conveyor belt.
