Sealing frame of furnace frame sealing device

Abstract

A sealing frame of a furnace frame sealing device comprises a two-sided frame, wherein the two-sided frame has its upper section vertically arranged with a shaft, the shaft is hoisted thereon with a lining plate via hinges, and the lining plate has its two ends arranged with semicircle arc plates; the two-sided frame has its inner side arranged with a support plate, the support plate is connected with an arc plate via hinges, and one end of the arc plate close to the hinge is arranged with a return spring; and the sealing frame is of truss structure, and has its front end surface integrally mounted with asbestos. By mounting the lining plate and arc plate at the inner side of the sealing frame via hinges, respectively, the invention can make up a gap generated between a coal cake and the frame via the lining plate and arc plate, and thus has good sealing effect. When in use, one end of the sealing frame with asbestos butts against a furnace stay, and the asbestos can effectively prevent damage of high temperature to the sealing frame. In addition, the sealing frame ensures its strength by adopting truss structure.

Description

Technical field: [0001] The invention relates to a sealing device for a coal charging opening of a coke oven machine applied to a side-mounted tamping coal charging car. Background technique: [0002] The coal material is tamped into coal cakes by the tamping machine in the coal tank of the tamping coal loading vehicle, and then the tamping coal loading vehicle puts the tamped coal cakes into the carbonization chamber, and the coal cakes are carbonized at high temperature in the carbonization chamber to generate coke . During the coal loading process, the side wall of the coal tank moves laterally away from the coal cake, and at the same time opens the front baffle of the coal tank, and starts the transmission mechanism to send the coal charging bottom plate of the coal tank together with the coal cake on it into the carbonization chamber, and the rear baffle of the coal tank Follow to the carbonization chamber. When the coal charging bottom plate is returned, the tailgate...

Problems solved by technology

[0003] In the above process, due to the influence of the positive pressure of the coke oven, a large amount of smoke and dust will overflow and the outside cold air will enter the carbonization chamber. The smoke and dust overflow will cause serious pollution to the surrounding environment. prone to danger

Therefore, it is necessary to equip the coal charging port of the coke oven machine with a sealing frame. The frame of the previous sealing frame is rigidly connected and the shape is fixed. If the height and width of the coal cake change, or the coal cake deviates from the center position, it will There is a gap between the cake and the frame, and it is difficult to ensure the sealing effect
