  • Patent number: 9897379
    Abstract: A shaft furnace charging device and cooling system includes a suspension rotor with a charge distributor and stationary housing. The cooling system includes an annular swivel joint arranged coaxially on an axis, connecting stationary and rotary circuit portions. The swivel joint includes forward connections for receiving cooling fluid from the stationary circuit portion and supplying cooling fluid to the rotary circuit portion; return connections for receiving cooling fluid from the rotary circuit portion; and returning cooling fluid to the stationary circuit portion. The swivel joint includes a partition dividing the annular volume into cavities wherein an internal cavity is partially surrounded by an external cavity, and the forward connections are coupled via one of the cavities and the return connections are coupled via the other of the cavities. The swivel joint includes leakage-permitting communication between the external and internal cavities through annular clearances.

  • Patent number: 9133529
    Abstract: 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.
