Abstract
A loading device for a shaft furnace comprises a chute supported by a suspension rotor () in a fixed housing. The rotor () is fitted with a cooling circuit, supplied with liquid coolant via a rotating annular joint (). The latter comprises a fixed ring () and a rotating ring (), and is fitted in an annular leak collecting tank () formed by the suspension rotor (). Fixed ring () is supported by the housing (). Rotating ring () is supported entirely by fixed ring () via a bearing (). Selective coupling means () connect the rotating ring () to the suspension rotor () in such a way as to transmit a rotary moment of rotor () to rotating ring () selectively, while at the same time preventing other forces from rotor () being transmitted to rotating ring ().
