ROTARY CHARGING DEVICE FOR SHAFT FURNACE Russian patent published in 2017 - IPC C21B7/20 F27B1/20 F27D3/00 F27D3/10 

FIELD: metallurgy.

SUBSTANCE: device contains a stationary housing for mounting on the throat of a shaft furnace and a mounted rotor installed in the stationary housing for rotation about a substantially vertical axis and forming the main annular chamber of the rotary charging device. The charge distributor is suspended so that it can pivot towards the mounted rotor. The device also contains rotation drive facilities for rotating the mounted rotor about its axis, independent tilt drive facilities for rotating the charge distributor about the substantially horizontal pivot axis independently from the rotation drive facilities. The rotation drive facilities contain a tilt motor with a horizontal output shaft, which is rigidly mounted in relation to the stationary housing, a tilt drive shaft in the main annular chamber which is installed on the mounted rotor. The first outward end of the tilt drive shaft is coupled to the tilt motor through a motion transmission facility and the opposite, second inward end of the tilt drive shaft is connected with the charge distributor for selective actuating its rotation. The motion transmission facilities are designed for peripheral actuation of the mounted rotor to provide for driving force transmittion from the tilt drive motor to the tilt drive shaft in any angular position of the mounted rotor. The motion transmission facilities contain a pair of rotationally integrated gear rims of large diameter, installed in the main annular chamber rotatable about the vertical axis. The first of the gear rims is coupled to the tilt drive motor to transmit the driving force, and the second gear rim is operatively connected with the first end of the tilt drive shaft in such a way that the rotation of the gear rims causes the suitable rotation of the tilt drive shaft about its axis.

EFFECT: ensured continuous charging.
