[0002] During the coke oven production process, the coal material is distilled at high temperature in the carbonization chamber to form coke, and the raw coal gas in the carbonization chamber forms tar and graphite at the junction of the furnace door and the door frame. When the coke interceptor and the coke quenching car are ready to receive the coke, the coke pusher starts the coke pushing operation. Every time the coke is pushed and the furnace door is opened, the tar and coke from the furnace door, furnace frame, and the upper part of the furnace head coke, as well as the tail coke brought out when the coke pusher slides back, all fall onto the coke flowing board, and the furnace door worker needs to use tools to manually clean them in front of the furnace.

[0003] The coke oven production environment is harsh. The temperature in front of the coke oven is over a thousand degrees, and the oven door opens and closes regularly. Since the workers' manual cleaning is slow, new tar will be stuck to the door after it is opened and closed before the cleaning is completed, resulting in high labor intensity for the workers.
