[0029] Please refer to Figures 1 to 3 , Figure 1 A front view schematic diagram of a specific embodiment of the coke oven door cleaning device provided by this utility model; Figure 2 A top view schematic diagram of a specific embodiment of the coke oven door cleaning device provided by this utility model; Figure 3 This is a side view schematic diagram of a specific embodiment of the coke oven door cleaning device provided by this utility model.

[0030] This utility model provides a coke oven door cleaning device, including a trolley 1, a support 2, an upper air knife 3, and side air knives 4. The trolley 1 is connected to the support 2, and the support 2 is moved by the trolley 1. Specifically, the power source of the trolley 1 can be a hydraulic drive system, with a copper drum hydraulic cylinder extending and retracting to drive the trolley 1 and the support 2 to move, or other drive methods such as motor drive can be used. Specifically, the upper air knife 3 is installed above the support 2, and multiple side air knives 4 are arranged on both sides of the support 2 to form a gantry structure. After moving into position, the upper air knife 3 is located above the glazed kiln door 17, and the two side air knives 4 are located on both sides of the glazed kiln door 17, with the air inlets of the upper air knife 3 and the side air knives 4 facing the glazed kiln door 17.

[0031] During operation, the trolley 1 drives the support 2 to move to the furnace door cleaning position. During this movement, the upper air knife 3 blows air to clean the top of the glazed furnace door 17. After moving into position, the side air knife 4 blows air to clean both sides of the glazed furnace door 17. During cleaning, a certain distance is maintained between the air knife and the glazed furnace door 17, preventing direct contact. The air pressure is used to blow and tap away the tar, achieving the purpose of cleaning the furnace door. This eliminates the problems of not being able to clean the glazed bricks of the furnace door and the wear and tear on the knife edges 18, preventing damage to the glaze, improving equipment reliability and safety, and extending service life. After the installation and implementation of this device, the coke oven door can be kept clean, preventing smoke problems during coke oven smelting, and further promoting the environmentally friendly production goals of the coke oven.

[0034] Furthermore, the upper end of the sealing shell 6 is open, and a movable sealing cover 7 is installed on the upper end of the sealing shell 6, along with a sealing actuator 8. During the movement of the device, the sealing actuator 8 opens the movable sealing cover 7, and after it has moved into place, the sealing actuator 8 closes the movable sealing cover 7, completely sealing the opening at the upper end of the sealing shell 6. Specifically, the movable sealing cover 7 can be two split plates, hinged to both ends of the sealing shell 6 via a hinge structure. The sealing actuator 8 can be a hydraulic cylinder, which drives the opening and closing of the two plates through extension and retraction. The sealing actuator 8 can also be a motor, etc. In addition, a dust collection trough 9 is installed at the lower end of the sealing shell 6, through which the swept particles are collected, achieving the effect of environmentally friendly operation.
