Description

Emergency Apparatus for Coke Ovens {AN APPARATUS FOR MOVING COKES OVEN CAR FOR EMERGENCY}

The present invention relates to an apparatus for emergency driving a coke oven tank, which is a mobile device of a coke oven facility, by a chain conveyor. More specifically, when the coke oven tank is incapable of driving, the coke oven tank is rapidly driven to emergency driving. Emergency driving system of the coke oven tank improved to prevent the damage of equipment caused by red coke in advance by safely driving the trucks and fire trucks to wet and dry fire extinguishing equipment and enabling fire extinguishing of loaded red coke. It's about.

Generally, coal charged in the carbonization chamber of the coke oven is coagulated by coagulation for a certain period of time. The coke coke is extracted from the carbonization chamber, and after extraction, it is extinguished in the digestion tower and cooling tower of wet and dry fire extinguishing facilities (CDQ). After the extinguishing, the cooling coke is transferred to the blast furnace and used as a heat source and breathable maintaining means to melt the water.

Figure 1 shows a typical coke operating plant. According to the coke production facility 200, when the coke oven 220 is extracted from the coke oven carbonization chamber 210 through the extruder facility 230, by the coke oven tank 240 moving on the rail 255. It is initially loaded in the towed wet fire truck 241 and the dry fire truck 242.

As shown in FIG. 2, the coke 220 is moved to the digestion tower 250 and the cooling tower 251 to be extinguished, and after digestion, is transferred to the blast furnace (not shown). Then, the work execution is continuously performed repeatedly.

In the process of repeating the operation as described above, the coke oven tank 240 is a certain distance (A-) between the dry fire extinguishing equipment 250 and the wet fire extinguishing equipment (251) from the carbonization chamber 210 receives the red coke (220). A ') is repeatedly driven on the rail 255, because the coke oven tank 240 is an electric vehicle driven by an electric power source in accordance with the conditions required for low speed, high power, power failure or power supply of the electric power unit If an error occurs in the device and the motor, the driving work is poor during the operation.

As described above, when the driving to the dry fire extinguishing facility 250 or the wet fire extinguishing facility 251 is poor and the vehicle is stopped in the middle, the heat that is towed and stacked on the fire truck 241 and the fire truck 242 of the coke oven tank 240 is maintained. Since the temperature of the coke 220 is 1100 ° C. or more, when the delay of 5 minutes or more is delayed, the storage box deformation of the fire truck 242 and the fire truck 241 occurs, and the other mobile device facility 231 located on the upper side. Problems leading to fire accidents have also occurred, which is an emergency situation in the coke oven.

Therefore, in the related art, the fire extinguisher coke 220 is extinguished using a fire hydrant (not shown) as the emergency action, or the coke is pushed out by a heavy equipment (not shown), and a wire loafer (not shown) is used. Towing the coke oven tank 240, various methods are used.

However, the former item is cumbersome because a separate fire extinguisher must be used, and the latter item is because the brake function of the coke oven tank 240 is released, and the weight of the coke oven tank 240 is heavy. 40 tons or more), the driving of the push is possible, but it does not stop easily to stop, so there is a great risk of work.

In addition, the wire traction is not used at present because the elastic phenomena, such as a rubber band during the traction operation, or a wire breakage phenomenon occurs, so that the action situation tends to be more difficult.

As such, the coke oven tank 240 takes a lot of maintenance time due to the peculiarity of the electric device when a trouble occurs, such as a bad driving, and thus a lot of equipment damage occurs continuously, so that an emergency driving device is necessary.

As a general emergency driving device of the coke oven tank 240, a wire traveling device (not shown) composed of a hoist structure is commonly used, but such a wire traveling device can be used in a case of low weight and short distance (less than 50M). However, heavy weight, long distance (more than 100M) is very inconvenient to use because the distance and inner diameter of the wire should be large.

In addition, the towing of the coke oven tank 240 should be equipped with a brake function, the device configuration should be very large capacity, accordingly the situation is not practical.

Therefore, there is a need for an emergency traveling device that can have a braking function in accordance with other heavy handling characteristics in addition to heavy towing.

The present invention is to solve the problems of the prior art as described above, the purpose of the coke oven tank loaded with the coke in the carbonization chamber is unable to run due to poor power supply, the coke oven tank at a constant speed and the digestion tower and It is to provide an emergency driving device of the coke oven tank improved to be able to run to the cooling tower to prevent fire accidents of the equipment, and to increase the productivity of maintenance work.
