A rotary charging device for a shaft furnace comprises a stationary housing () for mounting on the throat () of the shaft furnace and a suspension rotor () supported therein so that it can rotate about a substantially vertical axis (A), said suspension rotor () and stationary housing () cooperating to delimit an annular chamber forming the main casing () of said rotary charging device. A charge distributor () is pivotally suspended to the suspension rotor (). The device further comprises: rotary drive means for rotating the suspension rotor () about its axis; independent tilting drive means for pivoting the charge distributor () about a substantially horizontal pivoting axis (B) that include: a tilting motor (M) with horizontal output shaft () fixedly mounted relative to the stationary housing (); a tilting drive shaft () in the main housing () that is mounted onto the suspension rotor (), an outward end () of the tilting drive shaft () being coupled to the tilting motor (M) by motion transfer means () while the opposite inward end () of the tilting drive shaft is coupled to the charge distributor () to selectively operate its pivoting, the motion transfer means () being configured in such a way as to allow transmitting power from the tilting motor (M) to the tilting drive shaft () at any angular position of the suspension rotor ().

Rotary charging device for shaft furnace

A rotary charging device for a shaft furnace comprising: a stationary housing () and a suspension rotor () that is supported so that it can rotate about a substantially vertical axis (A), a charge distributor () being pivotally suspended to the suspension rotor (). Rotary drive means are provided for rotating the suspension rotor about its axis (A) and tilting drive means for pivoting the charge distributor () about a substantially horizontal pivoting axis (B), independently from said rotary drive means. The tilting drive means are mounted onto the suspension rotor () and rotate therewith; they comprise: an electric tilting motor (M) is installed inside the main casing () and having a substantially horizontal output shaft (); a tilting input gear () driven by the tilting motor output shaft; and a tilting output gear () rotationally integral with a suspension arm () of said chute distributor (), said tilting input gear meshing with said tilting output gear.

A shaft furnace charge material distribution device includes a main housing, a distribution chute, a suspension rotor and an adjustment rotor, which are rotatable about a vertical axis. The chute is suspended to the suspension rotor to rotate therewith for circumferential distribution of charge material and is adjustable in orientation for radial distribution of charge material. A differential gear interconnects the suspension rotor and adjustment rotor and is configured to transmit to the adjustment rotor the same speed of rotation that is imparted to the suspension rotor by a main rotation drive unless an adjustment drive imparts differential rotation to the adjustment rotor. The device includes two gear casings arranged on the main housing and a shaft arrangement. The first gear encloses a gear mechanism connecting the main rotation drive to one output shaft. The second gear casing encloses the differential gear connecting the adjustment drive to another output shaft.
