LOADING APPARATUS OF A BLAST FURNACE Russian patent published in 2022 - IPC C21B7/20 F27B1/20 F27D3/10 

FIELD: furnaces.

SUBSTANCE: group of inventions relates to a loading apparatus for feeding charge material into a blast furnace, in particular, to a mechanism for changing the angle of inclination of the chute of such apparatus. Loading apparatus (1) comprises a transition channel (3) for charge material, defining a first axis (Y), a chute (5) for feeding charge material, located below the transition channel (3), a first annular body (60) coaxial to the transition channel (3), located outside of the channel (3), and configured to rotate around a first axis (Y), a second annular body (10) coaxial to the first annular body (60), located outside said body, and configured to move translationally along the first axis (Y) relative to the first annular body (60) and/or rotate around the first axis (Y) together with the first annular body (60), a rail (11, 12) attached to the second annular body (10) and placed parallel to the first axis (Y), two shafts (21, 22) with a common second axis (X) transverse to the first axis (Y), placed on opposite sides relative to the transition channel (3) and crossing the second annular body (10) and the first annular body (60), a gear wheel (31, 32) engaging with at least one fixed rail (11, 12) and attached to one shaft (21) from said two shafts (21, 22).

EFFECT: loading apparatus is compact, secure, allows for a high degree of accuracy in changing the angle of inclination of the chute.
