摘要： The invention relates to a distribution chute (100) for a charging device of the rotary pivotal type, e.g. for a shaft furnace. The chute has an upstream mounting head (114) and a chute body (112) having an elongated downstream chute portion (116) with a longitudinal axis (L). It further includes at least two lateral suspensions (130) at the mounting head for mounting the chute to at least two corresponding support flanges of the charging device, the support flanges (140) being pivotable about the pivoting axis (B) in a raising sense (R) for raising the outlet (120) to a radially outermost charging position and in an opposite lowering sense for lowering the outlet to a radially innermost charging position with respect to the rotational axis. The suspensions (130) define a first and a second tilt points, which define, in turn, a tilt axis (T), about which the weight of the chute exerts torque onto support flanges of the charging device when the chute is mounted. The suspensions are configured in such a way that the ratio of the distance between the tilt axis and the pivoting axis to the distance between the first and second tilt points (which corresponds at least approximatively to the distance between the suspensions) amounts to 0.25 at most. According to the invention, the suspensions (130, 230, 330) are arranged so that an acute angle (a) from the longitudinal axis (L) to a virtual plane (P) through the tilt axis (T) and the center of gravity (G) of the chute has an angular measure in the raising sense (R) that has a small positive or a negligibly negative value.

摘要： 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).

摘要： A multiple hopper charging installation (10, 10') for a shaft furnace comprises a rotary distribution device (14) for distributing bulk material in the shaft furnace (12) by rotating a distribution member about a central axis (A) of the shaft furnace and at least two hoppers (20, 22) arranged in parallel and offset from the central axis above the rotary distribution device. Each hopper has a lower funnel part (76) ending in an outlet portion (78) and each hopper has a material gate valve (82) with a shutter member (84) associated to its outlet portion. According to the invention, each funnel part (76) is configured asymmetrically with its outlet portion (78) being eccentric and arranged proximate to the central axis (A), each outlet portion (78) is oriented vertically so as to produce a substantially vertical outflow (140) of bulk material and each material gate valve (82) is configured with its shutter member (84) opening in a direction pointing away from the central axis (A) such that any partial valve opening area is located on the side of the associated outlet portion (78) proximate to the central axis (A).

摘要： A distribution chute (10) of the rotate-and-pivot type comprises a chute body (12) having therein a channel (22) with an inlet (20) for receiving a flow of bulk material and an outlet (24) for discharging the bulk material. In operation, the channel conveys the bulk material from the inlet to the outlet. The channel has a bend (28) to divert the flow of material from a first flow direction in the inlet into a second flow direction in the outlet. The chute body is assembled of at least an upstream part (14), which comprises the inlet, and a downstream part (16), which comprises the outlet and which is fixed to the upstream part. The downstream part defines a straight portion of the channel, whereas the upstream part defines the inlet and the bend of the channel. The upstream part is thick-walled with respect to the downstream part.
