Description

Technical Field

[0001] The present invention relates to the technical field of coke oven doors, and more specifically, to a coke oven door with an adjustable eccentric roller on a cavity web Background Art

[0002] Coke oven doors are divided into two types: the machine-side coke oven door and the coke-side coke oven door. They are devices for opening and closing the two ports of the coke oven carbonization chamber. When the coke oven door is closed, the carbonization chamber is isolated from the atmosphere. When it is opened, the pusher can push out the coke. Whether the coke oven door is tightly sealed is closely related to preventing smoke and fire, protecting the environment, and the deformation and failure of the oven door frame and oven columns. The existing 7.63-meter coke oven is currently the coke oven with the highest carbonization chamber height and the largest single-hole carbonization chamber volume in China. It is an advanced coking process technology introduced from abroad and represents the development direction of the current coking process technology. The coke oven door plays a role in sealing and heat insulation during the coking production process. The coke oven door includes a door body, a brick groove, a door lining, a door web, and a sealing edge. The sealing edge is rigidly pressed on the sealing surface of the oven door frame of the carbonization chamber. The sealing edge of the coke oven door, the door web, the oven door frame, and the brick groove form a closed space. During the process of coal dry distillation in the carbonization chamber, some high-temperature raw coal gas and soot gather in this space.

[0003] During the use of the coke oven door, it needs to be frequently removed and hung. Under the condition of heat, the shrinkage of the stainless-steel sealing edge and the cast-iron door body is inconsistent. At a working temperature of 200 °C, the expansion amount of the sealing edge and the door body in the length direction differs by about 9 mm, resulting in a gap between the sealing edge and the door body, accompanied by torsional deformation, causing the leakage of flue gas and tar in the oven. At the same time, due to the influence of the welding position of the sealing edge and the web, the retaining edge at the lower end of the traditional top pressure block is short, which may lead to the situation of falling off during the process of removing the door.

[0004] For the problems in the related art, no effective solution has been proposed yet. Summary of the Invention

[0005] In view of the problems in the related art, the present invention provides a coke oven door with an adjustable eccentric roller on a cavity web to overcome the above-mentioned technical problems existing in the related art.
