charging device for a shaft furnace, distribution chute for thereof and method for disposing of the distribution chute

摘要

A charging device (14) for a shaft furnace, in particular for a blast furnace (10) and a cooperating distribution chute (22) are proposed. The distribution chute (22) has an elongated chute body (24) providing a sliding channel for bulk material and two chute-mounting members (28) attached laterally to either side of the chute body (24) for mounting the distribution chute to the charging device (14). The charging device comprises a mechanism for rotating the distribution chute, the mechanism having a rotatable support rotor (16) with two suspension flanges (20) cooperating with the chute-mounting members (28) of the distribution chute (22) for mounting the distribution chute. Each chute-mounting member (28) of the chute (22) comprises a hook-shaped portion (32) that forms a suspension hook for mounting the distribution chute (22) to the suspension flanges (20). Each suspension flange (20) in turn has a support (23) configured for engagement with the hook-shaped portion (32) of the chute (22) along a hook engagement direction (C). Furthermore, each chute- mounting member (28) comprises an abutment portion (59) that cooperates with a counter-abutment (62) on the corresponding suspension flange (20) to provide abutment in a direction transversal to the hook engagement direction (C) so as to preclude pivoting of the chute (22) about the supports (23) of the suspension flanges (20).
