Description

Technical Field

[0001] The utility model belongs to the technical field of furnace door frame cleaning, and in particular relates to a cleaning device for a carbonization chamber furnace door frame. Background Art

[0002] During the coking process, coke ovens will produce tar, dust and other debris, which will adhere to the door frame of the carbonization chamber. If not cleaned in time, they will gradually accumulate into thick ash and dirt, resulting in the carbonization chamber door being unable to fit tightly with the door frame when closing the carbonization chamber door, causing a large amount of raw coal gas to leak out, which not only wastes resources but also seriously pollutes the environment. The door frame cleaning device cleans the mirror surface and inner side of the door frame to remove tar and coal coke to ensure that after the carbonization chamber door is closed, the carbonization chamber door and the door frame remain tightly together, which can control gas leakage and smoke and protect the environment. Therefore, the door frame cleaning device is an indispensable equipment for maintaining normal coking production.

[0003] In the prior art, the furnace door frame cleaning device is installed on a cleaning frame moving trolley. When working, the cleaning device is pushed against the furnace door frame by the moving trolley, and the cleaning scraper is driven up and down by the oil cylinder inside the cleaning device to clean the mirror surface and the inner side of the coke oven door frame. The cleaning scraper of the traditional furnace door frame cleaning device is arranged horizontally, which is not conducive to the scraped tar and coke powder falling off, and is easy to accumulate on the cleaning scraper, affecting the subsequent cleaning effect. In addition, the heat radiation protection plate is only a thin plate with poor heat insulation effect, poor strength, and easy deformation. In addition, the traditional furnace door frame cleaning device is not provided with a guide device, which easily causes the cleaning device to be misaligned when entering the carbonization chamber, resulting in the situation that the cleaning scraper on one side sticks to the furnace surface and the cleaning scraper on the other side does not contact the furnace surface. In summary, there is an urgent need for a cleaning device for the furnace door frame of the carbonization chamber that can automatically align. Utility Model Content
