Claims

[Scope of utility model registration request]

A sealing device that airtightly seals the opening of a rotationally driven cylinder such as a rotary kiln, and is a cylindrical seal fixed to the opening end of the cylinder main body H coaxially with the main body H. A metal fitting 1 and a plurality of seals arranged adjacent to each other along the circumferential direction of the sealing surface 1a with their inner circumferential surfaces in close slidable contact with the sealing surface 1a, which is the outer circumferential surface of the sealing fitting 1. At least one end of a band 6, which has both ends connected to the block 2 and a hood 10 which is placed and fixed immovably by fitting the open end of the main body H into the sealing block 2, is connected to the band. a tightening device 4 that presses the seal block 2, which is constituted by a plurality of tightening bodies 5 coupled to the hood 10, against the sealing surface 1a through a tensioning body 7 that applies a tensile force to the hood 6, and a shaft of the main body H. A sealing device for a cylindrical opening comprising a seal guide plate 3 fixed to the hood 10 with guide surfaces in contact with both end faces of the seal block 2 to prevent displacement of the seal block 2 in the center direction. .
