  • 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: 9073693
    Abstract: A distribution chute for a charging device, a charging device having the same, and a methods for mounting and dismounting such chute, the chute including an upstream mounting head and a chute body, at least two lateral suspensions on the mounting head for mounting the chute to two corresponding support flanges pivotable about a pivoting axis for raising an outlet to a charging position and for lowering the outlet to a charging position, where the suspensions define a first and a second tilt point about which a weight of the chute exerts torque onto the support flanges of the charging device when the chute is mounted to the charging device, where the ratio of the distance between each of the tilt points and the pivoting axis to the distance between the first and second tilt points amounts to 0.25 at most, the suspensions being arranged so that an oriented acute angle from the longitudinal axis to a plane through the tilt points and the center of gravity has an angular measure in the range from ?5° to 15°.

  • Publication number: 20140131162
    Abstract: The invention relates to a distribution chute (100) for a charging device of the rotary pivotal type, e.g. for a shaft furnace. The chute has an upstream mounting head (114) and a chute body (112) having an elongated downstream chute portion (116) with a longitudinal axis (L). It further includes at least two lateral suspensions (130) at the mounting head for mounting the chute to at least two corresponding support flanges of the charging device, the support flanges (140) being pivotable about the pivoting axis (B) in a raising sense (R) for raising the outlet (120) to a radially outer-most charging position and in an opposite lowering sense for lowering the outlet to a radially innermost charging position with respect to the rotational axis. The suspensions (130) define a first and a second tilt points, which define, in turn, a tilt axis (T), about which the weight of the chute exerts torque onto support flanges of the charging device when the chute is mounted.
