Coke oven door sealing device

Abstract

The invention provides a coke oven door sealing device applied to the field of coke ovens. The web knife edge (3) of the coke oven door sealing device is connected with an oven door refractory material cast block (2), the oven door refractory material cast block (2) is connected with an oven door body (1) through a connecting long rod (4), the elastic part (5) of the coke oven door sealing device is connected with the oven door body (1), the spring (6) of the elastic part (5) presses and leans on a pressure shaft (7), and the pressure shaft (7) is a structure abutting on the web knife edge (3). The coke oven door sealing device effectively solves the problem of a gap between the knife edge and the oven door body, ensures the sealing performance between the knife edge and an oven door frame, and allows the sealing surface pressure of the knife edge to be ensured and the gap between the knife edge and the oven door body to be elastically compensated with the continuously growing life of the coke oven in order to ensure the working performances of the coke oven.

Description

technical field [0001] The invention belongs to the field of coke oven machines, and more specifically relates to a coke oven door sealing device. Background technique [0002] The sealing of the furnace door of the coke oven machine mainly depends on the rigid contact between the knife edge and the furnace door frame. When there is a gap between the knife edge and the furnace door frame, the seal will not be tight, and smoke and fire will occur, which will seriously pollute the site environment and aggravate the furnace protection. Iron parts are damaged. At present, coke oven machines generally use Z-shaped knife edge, and its initial sealing effect is good. As the service life of the coke oven machine increases, the deformation of the furnace door frame increases, and the seal between the knife edge and the furnace door frame gradually deteriorates. In the end, it cannot be adjusted, resulting in serious smoke. The Z-shaped knife edge assembly needs to use the shrink fi...

AI Technical Summary

Problems solved by technology

The gap between the Z-shaped knife edge and the furnace door body is prone to smoke, and the sealing effect cannot be guaranteed

The size of the cantilever between the knife edge opening and the knife edge fixed point of the Z-shaped knife edge is small, the adjustment rigidity is large, and the efficiency of the adjustment mechanism is low. When there is a large gap between the knife edge and the furnace frame, it cannot be adjusted in place.

In view of the above-mentioned shortcomings such as the short life of the Z-type knife edge, poor sealing effect and small adjustment range, it cannot meet the needs of the actual coke oven machine field.
