Dislocation starting device of coke oven cover and application method of dislocation starting device

Abstract

The invention relates to the field of furnace-roof vehicle-mounted smoke guiding tubes of tamping coke ovens of coking plants and particularly relates to a dislocation starting device of a coke oven cover and an application method of the dislocation starting device. The application method is characterized in that an outer sleeve of the starting device is firstly mounted at the lower end of a smoke guiding tube, and an ear handle oven cover is arranged on a coking chamber furnace mouth; and when coals are charged in a tamping coke oven, the smoke guiding tube is aligned above the coking chamber furnace mouth and covers the coking chamber furnace mouth under the action of a smoke guiding tube lifting mechanism, push handles on the starting device are meshed with ear handles on the ear handle oven cover, an air cylinder repeatedly carries out stretching action, the push handles pushes the ear handle oven cover to perform rotation and dislocation on the horizontal plane to break binding power of oven cover sealing slurry, and an oven cover lifting mechanism is opened to lift up the ear handle oven cover. Compared with the prior art, the dislocation starting device of the coke oven cover and the application method have the advantages that the binding power of the oven cover sealing slurry between the oven cover and an oven body is overcome by utilizing an dislocation rotation motion, so that safe separation between the oven cover and the oven body is realized, and the rigid breaking of the oven body caused by direct lifting is avoided.

Description

technical field [0001] The invention relates to the field of vehicle-mounted smoke guide pipes for tamping coke ovens in a coking plant, in particular to a staggered opening device for a coke oven cover and a method for using the same. Background technique [0002] At present, when domestic coking plants tamp coke ovens to deal with the problem of flue gas escape during coal charging, they mainly use the combination of smoke guides on the top of the furnace and ground dust removal stations for furnace smoke. [0003] See attached figure 1 , when a certain carbonization chamber of the tamping coke oven needs to be charged with coal, the furnace top smoke guiding vehicle (1) first drives to the top of the coal charging chamber, and adjusts the alignment so that one end of the smoke guiding pipe (2) is aligned with the coal charging chamber chamber furnace mouth (18), and the other end of the smoke guide pipe is aimed at another carbonization chamber furnace mouth which is in ...

AI Technical Summary

Problems solved by technology

[0012] The above-mentioned technological process has great potential safety hazards and problems affecting the normal and stable production of the furnace when the smoke is introduced.

The problem lies in the above-mentioned fourth and seventh steps, which are mainly manifested in: when the workers use the furnace cover sealing slurry (6) to seal, a strong adhesive force will be formed, and then when the fourth step is performed, The furnace cover is lifted up by the "raw and hard pull" operation method, because the furnace cover lifting mechanism only acts on the furnace cover in the vertical direction. In production practice, the furnace body is often damaged under the action of the cohesive force of the furnace cover. Phenomena, including the destruction of furnace body components, form a great safety hazard, and also seriously affect the stable and normal production of coke ovens
