摘要：It is an object to provide a sealing structure for a solid-transferring screwinstalled inside a heating furnace 1 such as a material-leveling screw and a product-discharging screw, the sealing structure enabling the solid-transferring screw 3 to belifted during the operation while airtightness of the heating furnace 1 is retained. Drivingshaft 4 of the solid-transferring screw 3 passes through through-holes 6 formed in sidewalls 2 of the heating furnace 1 and is supported by liftable supporting devices 7
disposed at the outsides of the furnace. Sealing blocks 8 are attached on the outer edges6a of the through-holes 6 to surround the periphery of the through-holes 6 at theoutsides of the furnace. Sliding panels 9 are disposed at the outer sides of the sealingblocks 8 of the furnace and have sliding holes 10 for sliding the screw-driving shaft sothat the driving shaft 4 extends through the sliding holes. The sliding panels 9 arebrought into contact with the sealing blocks 8 via the sealing members 11 therebetweenso that the sliding panels are slidable in the vertical direction.
