It works.

According to an embodiment of the present invention, the waste gas generated after the combustion in the combustion chamber of the coke oven is discharged to the outside through the waste stool 10 to the waste stool damper 16 for controlling the amount of waste gas under the waste stool 10 ) Can be automatically opened and closed to stabilize the gas pressure burned in the combustion chamber of the coke oven. That is, since the waste gas generated after the combustion gas is combusted in the combustion chamber in the coke oven is constantly controlled by the opening / closing operation of the waste valve damper 16, the combustion efficiency of the combustion gas in the combustion chamber is changed, so that the coke inside the carbonization chamber is It directly affects quality. Therefore, the coke production quality can be improved. And it can alleviate the burden of working hours in high temperature area. In addition, it is possible to prevent the air pollution caused by the combustion chamber incombustible combustion, and to extend the life of the waste toilet equipment.

Previously, the wastewater dampers installed in the wastewater of the coke oven were individually adjusted by the operator. As the waste gas is discharged from the combustion chamber, the ambient temperature of the waste stool becomes high temperature, and the carbon and various foreign substances contained in the waste gas are gradually accumulated on the waste stool damper shaft, which gradually accumulates in the waste stool damper shaft. Since it was not adjusted, coolant was put in between the damper shaft operating part to melt carbon and various foreign substances in the damper shaft fixing part. In this way, by managing the waste damper operating part, the pressure during combustion of the combustion chamber in the coke oven due to the fixing of the waste damper operating part was frequently changed. Since the pressure adjustment is not easy to adjust to such a pressure change, the combustion gas inside the combustion chamber causes air pollution that frequently causes incombustible combustion, and worker hours have been gradually increased in the high temperature region.

If the waste damper shaft is stuck, a plurality of waste dampers are often manually operated and replaced by alternating odd-numbered and even-numbered ones more than 85 degrees.

Embodiments of the present invention provide that the waste side 10 of the coke oven alternates between odd and even while the waste side 10 upper spindle 12 and disk 14 are raised and lowered every 20 minutes by a reversing winch cylinder. Accordingly, the corresponding waste valve damper 16 is also linked to open and close. Therefore, the waste valve dampers 16 corresponding to the plurality of waste valve dampers 16 manually adjusted by the operator are automatically opened and closed.

To this end, power is transmitted to the rack gear 32 and the pinion gear 34 by the waste damper cylinder 30 connected to the hydraulic line of the reversing winch cylinder, and finally, the power is applied to the corresponding waste damper 16. This is transmitted and opened and closed every 20 minutes to prevent the waste valve damper shaft from sticking.

According to the embodiment of the present invention, the waste valve damper cylinder 30 is connected to the hydraulic line of the reversing winch cylinder every 20 minutes so that the spindle 12 and the inner disk 14 of the waste valve 10 have a plurality of odd and even numbers. When alternately moving, the waste valve damper operation cylinder is also moved in odd and even numbers as shown in Figure 1 to repeat the operation of opening and closing the corresponding waste valve damper 16 every 20 minutes. In this control operation, the waste gas generated after being combusted in the combustion chamber of the coke oven is discharged to the chimney through the corresponding waste stool 10 and the small smoke. According to the embodiment of the present invention, the waste valve damper shaft 16 may be automatically opened and closed to prevent the waste valve damper shaft from being stuck.
