Document Type and Number:
Japanese Patent JP5422568
Kind Code:
B2
Abstract:
The present invention proposes a charge distribution apparatus for a furnace comprising a charge distribution chute and a drive mechanism (12) with a first rotary drive shaft (14) for rotating the charge distribution chute and a second rotary drive shaft (16) for changing the angle of inclination of the charge distribution chute. The first and second drive shafts (14, 16) are coupled to respective first and second motors (18, 22) via a planetary gear mechanism (20) for driving the first and second drive shafts (14, 16). Each of the first and second rotary drive shafts (14, 16) have a first end (24, 24′) with a first pinion (26, 26′) interacting with the planetary gear mechanism (20) and a second end (28, 28′) with a second pinion (30, 30′) interacting with the charge distribution chute, the second end (28, 28′) of the rotary drive shaft (14, 16) extending through a furnace wall (32) into the furnace, a primary sealing element (46, 46′) being arranged between the furnace wall (32) and the rotary drive shaft (14, 16). The first rotary drive shaft (14) has a first rotation axis and the second rotary drive shaft (16) has a second rotation axis arranged parallel to and at a certain distance from the first rotation axis. A hollow socket (34, 34′) is provided in the furnace wall (32) for each of the rotary drive shafts (14, 16), the socket (34, 34′) comprising a first end (36, 36′) outside the furnace and facing the drive mechanism (12) and a second end (38, 38′) inside the furnace and facing the second pinion (30, 30′), the rotary drive shaft (14, 16) extending through the socket (34, 34′). The second end (38, 38′) of the socket (34, 34′) comprises a second end-wall (42, 42′) wherein the primary sealing element (46, 46′) is arranged between the socket (34, 34′) and the rotary drive shaft (14, 16), so as to face the second pinion (30, 30′), the second pinion (30, 30′) being removably connected to the rotary drive shaft (14, 16).
