Technical Field
[0001] The utility model belongs to the technical field of mechanical seals and relates to a sealed coke pushing rod. Background Art
[0002] In the coking industry, the hammered coal cakes are usually transferred to the coke oven and formed into coke through high-temperature carbonization in the coke oven. Among them, the coke pusher is used to push the coke in the coke oven to push the prepared coke out of the coke oven. At present, the existing coke pusher has a flat plate structure at the part in contact with the coke in the coke oven. Since the coke is prepared from coal cakes in the coke oven, the coke prepared in the coke oven is agglomerated and adhered to each other, so that when the existing coke pusher is used to push the coke, there is a phenomenon of air leakage in the coke pushing process. For this reason, a sealing sleeve is used for sealing, thereby improving the safety of equipment and personnel, and also strengthening the environmental management of leakage, bubbling, dripping and leakage on site.
