Abstract

A rotary charging device for a shaft furnace comprises a stationary housing (16) for mounting on the throat (12) of the shaft furnace and a suspension rotor (22) supported therein so that it can rotate about a substantially vertical axis (A), said suspension rotor (22) and stationary housing (16) cooperating to delimit an annular chamber forming the main casing (36) of said rotary charging device. A charge distributor (28) is pivotally suspended to the suspension rotor (22). The device further comprises: rotary drive means for rotating the suspension rotor (22) about its axis; independent tilting drive means for pivoting the charge distributor (28) about a substantially horizontal pivoting axis (B) that include: a tilting motor (M_B) with horizontal output shaft (52) fixedly mounted relative to the stationary housing (16); a tilting drive shaft (58) in the main housing (36) that is mounted onto the suspension rotor (22), an outward end (60) of the tilting drive shaft (58) being coupled to the tilting motor (M_B) by motion transfer means (64) while the opposite inward end (62) of the tilting drive shaft is coupled to the charge distributor (28) to selectively operate its pivoting, the motion transfer means (64) being configured in such a way as to allow transmitting power from the tilting motor (M_B) to the tilting drive shaft (58) at any angular position of the suspension rotor (22).
