[0002] In the early days, the knife edge sealing device of the coke oven door mainly relied on manual adjustment and used a simple mechanical device for preliminary sealing. Due to the limited mechanical precision, the sealing effect was not ideal, which easily caused smoke and gas leakage. With the development of mechanical technology, spring pressure devices began to be used to achieve the compression of the oven door. The spring can provide continuous pressure, improve the sealing effect, and reduce leakage problems. Elastic fillers such as asbestos boards or refractory fiber mats are added between the oven door and the furnace wall to enhance the sealing effect. The knife edge compression sealing device of the coke oven door comprises a compression device, a knife edge seal, an oven door frame and a control system. However, during use, the existing knife edge compression sealing device of the coke oven door cannot effectively seal the knife edge of the coke oven door due to the compression structure and the insulation mechanism. Therefore, the above technical problems need to be solved. Utility Model Content
