[0002] In the existing coke oven, a furnace cover is installed on the furnace ring of the coke oven. The furnace cover and the furnace ring are sealed by the line formed by the cooperation of the upper and lower spherical surfaces to completely seal the furnace mouth. When exhausting smoke, remove the The furnace cover and the duct of the smoke guiding device are connected with the furnace ring of the furnace mouth, so as to carry out the operation of smoke extraction and dust removal. However, because the sealing surface between the furnace ring and the duct of the smoke guiding device is single, the alignment is difficult, and the sealing performance is likely to be poor. , the seal is not tight, which leads to the occurrence of pollution

The invention discloses a sealing structure of a furnace body and a smoke guide device. A spherical sealed interconnecting sleeve is arranged on a side guide pipe of the smoke guide device, and consists of an upper spherical sealed interconnecting sleeve and a lower spherical sealed interconnecting sleeve, wherein the upper spherical sealed interconnecting sleeve is connected with the end part ofthe side guide pipe through a flange disc; the lower part of the lower spherical sealed interconnecting sleeve and a furnace ring are in spherical sealing; spherical sealing is formed between the upper parts of the upper spherical sealed interconnecting sleeve and the lower spherical sealed interconnecting sleeve; and the upper spherical sealed interconnecting sleeve and the lower spherical sealed interconnecting sleeve are in soft connection. The lower part of the spherical sealed interconnecting sleeve and a furnace mouth are in spherical sealing; the upper parts of the upper spherical sealed interconnecting sleeve and the lower spherical sealed interconnecting sleeve are matched to produce secondary sealing; and the upper spherical sealed interconnecting sleeve and the lower spherical sealed interconnecting sleeve are in soft connection, thereby achieving the functions of free contraposition and universal connection and having good sealing effect.
Description
technical field [0001] The invention relates to a sealing structure, in particular to a sealing structure between a coke oven and a smoke guiding vehicle. Background technique [0002] In the existing coke oven, a furnace cover is installed on the furnace ring of the coke oven. The furnace cover and the furnace ring are sealed by the line formed by the cooperation of the upper and lower spherical surfaces to completely seal the furnace mouth. When exhausting smoke, remove the The furnace cover and the duct of the smoke guiding device are connected with the furnace ring of the furnace mouth, so as to carry out the operation of smoke extraction and dust removal. However, because the sealing surface between the furnace ring and the duct of the smoke guiding device is single, the alignment is difficult, and the sealing performance is likely to be poor. , the seal is not tight, which leads to the occurrence of pollution. Contents of the invention [0003] The present invention...
