| 摘要 |
A blast furnace charging device comprises a feed conduit (8) central to the vertical axis (XX') and a mobile chute (11) rotating around a transverse axis (YY'). The chute (11) is articulated on a support casing (12) arranged at the lower end (10) of a circular shaft (9) that can rotate around the vertical axis (XX'). This circular shaft (9) comprises an upper main pinion (20) cooperating with a first control pinion (25) put in rotation by a main drive shaft (M1) and a secondary pinion (21) cooperating with at least one satellite pinion (34,34a,34b) of which the vertical axis (ZZ') is integral with an intermediate pinion (29) rotating around the vertical axis (XX') and that is engaged by a second control pinion (33) rotated by a secondary drive shaft (M2), the pivoting axis (28a,28b) of the satellite pinion (34a,34b) comprising at least one crank (27a,27b) connected to an operating arm (16a,16b) on the chute (11) via a lateral link rod (26a,26b). USE/ADVANTAGE - Used for charging raw materials into a blast furnace. The movements of the chute associated allow a uniform distribution of the materials charged to the blast furnace by pivoting at will the feed chute in the two directions (R1,R2) to place it at the desired position.
