A device for cooling the supporting trunnions of a distribution spout of a charging installation of a shaft furnace, wherein the spout is mounted pivotably about a horizontal axis on a shell coaxial with the furnace and the spout is attached rotatably to the trunnions driven in rotation by a drive component. The trunnions are directly attached for rotation by their ends to output shafts of reduction gears and include internal cooling channels. The cooling device includes feed and return ducts for the cooling water circulating in the internal channels. The feed and return ducts are connected to the trunnions by connectors fixed to the cylindrical surface of the trunnions. The feed and return ducts are arranged to permit rotational displacement of the connectors about the pivot axis of the spout during pivoting of the spout, in particular by passing through oblong slots extending circumferentially in the wall of bearings supporting the driving reduction gears.

A sealing valve arrangement for a shaft furnace charging installation, said arrangement comprising: a shutter arranged for cooperating with a valve seat; an integrated dual-motion shutter-actuating device for moving said shutter between a sealed closed position in sealing contact with the valve seat and an open position remote from the valve seat, said integrated dual-motion shutter-actuating device comprising: a primary motion assembly for moving said shutter from said sealed closed position to an undamped position wherein the shutter is released from the valve seat; a secondary motion assembly for tilting said shutter from said undamped position to said open position remote from the valve seat, said secondary motion assembly comprising a tilting arm carrying said shutter and connected to a tilting shaft that defines an axis of rotation and a tilting shaft actuator configured to impart an angular rotation about said axis to said tilting arm; wherein said integrated dual-motion shutter-actuating device further comprises a stationary outer cylindrical sleeve, wherein said primary motion assembly comprises an inner eccentric sleeve shaft rotationally mounted within said outer cylindrical sleeve and a primary motion actuator configured to impart angular rotation to said inner eccentric sleeve shaft, the primary motion being a function of the eccentricity and angular rotation of the inner eccentric sleeve shaft; and wherein said tilting shaft of said secondary motion assembly is rotationally mounted within said inner eccentric sleeve shaft of said primary motion assembly, the secondary motion being a function of the angular rotation of the tilting shaft.

A distribution device for distributing bulk material with a distribution spout on a cardan suspension that has a first and a second gimbal member pivotable about two perpendicular suspension axes where a drive arrangement has a first and a second transmission mechanism for controlling pivotal motion of the distribution spout about the suspension axes, and the drive arrangement has a further cardan joint, with a first part pivotable about a third axis and a second part pivotable about a fourth axis, and a rotary motor for driving a rotary drive shaft that is connected to the cardan joint by means of an articulated connecting arm such that the rotational position and the axial position of the drive shaft determine the pivotal position of the second part about the third and fourth axes respectively, where the transmission mechanisms transmit torque about the third and fourth axes from the cardan joint to the cardan suspension for pivoting the distribution spout about the first and second axes respectively.
