Abstract:
A self-supported rotary joint for introducing steam into a heat exchanging drum rotating about an axis of rotation, comprising, in combination, an elongated tubular bearing housing adapted to be affixed to the drum concentric to the drum's axis of rotation for rotation with the drum, a tubular nipple concentric with the drum axis of rotation within said bearing housing, a bearing means mounted within said housing interposed between said housing and said nipple supporting said nipple, a rotary joint body head, a frangible means connecting said body head to said nipple, a steam inlet defined in said body head in communication with a steam tube having an outer end extending through said nipple and an inner end located within the drum, and an anti-rotation means defined on said body head resisting rotation of said body head about the drum axis of rotation, said frangible means fracturing upon torque force imposed upon said body head by said nipple exceeding a predetermined value.
