    • PROBLEM TO BE SOLVED: To provide a rotary heating device comprising a sealing device having a simple constitution, stably developing sufficient sealability, and simplifying its maintenance check. SOLUTION: A cylindrical body 711 having an inner peripheral face opposite to an outer peripheral face of a rotary furnace through a heat insulating layer filled with a heat insulating material 712, is approximately coaxially mounted on an outer peripheral face of an end portion of a rotary furnace 200. A supporting portion 720 of a cylindrical structure is projected from an end face where the rotary furnace extends, of a discharge-side hood 600 rotatably converting an end portion of the rotary furnace, in opposition to the cylindrical body. A plurality of plate-shaped elastically deformable plate springs 731 are arranged in the circumferential direction of the cylindrical body in a state of being slidably kept into contact with an outer peripheral face of the cylindrical body, and detachably mounted on the supporting portion, thus an annular seal structure 730 is constituted to define an airtight chamber 770 approximately airtightly to the external, by the outer peripheral face of the cylindrical body and the supporting portion. As the heat quantity of the cylindrical body is little, the cylindrical body is hardly deformed, and the uniform slidable contact can be secured at all times. COPYRIGHT: (C)2006,JPO&NCIPI
