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.

Abstract: A shaft furnace charging device equipped with a cooling system, the charging device including a suspension rotor with a charge distributor and a stationary housing supporting the suspension rotor so that the rotor can rotate about an axis; the cooling system including a stationary circuit portion, a rotary circuit portion arranged on the suspension rotor, and an annular swivel joint arranged coaxially on the axis and connecting the stationary circuit portion with the rotary circuit portion, the annular swivel joint including an annular fixed part mounted on the stationary housing and an annular rotary part mounted on the suspension rotor, the fixed part and the rotary part having mating configurations that allow relative rotation and including an annular trough that defines an annular volume, via which the circuit portions are in fluidal communication; wherein the annular swivel joint includes: a stationary forward connection for receiving cooling fluid from the stationary circuit portion; a rotary forward co
