Vibration Device for an Apparatus for Conveying a Metal Charge to a Melting Plant

摘要

Vibration device for a conveying apparatus (21) to convey a metal charge in a longitudinal direction (X) comprising at least two vibration mechanisms (25, 26) each disposed on opposite sides of the conveying apparatus (21) so as to feed the metal charge. The vibration mechanisms (25, 26) comprise at least a first plurality of eccentric masses (31, 32, 33) having their mass barycenters (B) oriented in parallel directions to each other, and a second plurality of eccentric masses (34, 35) having their mass barycenters (B) disposed angularly offset with respect to the disposition of the barycenters of the first plurality of eccentric masses (31, 32, 33).

1. Vibration device for a conveying apparatus to convey a metal charge in a longitudinal direction comprising at least two vibration mechanisms each disposed on opposite sides of said conveying apparatus so as to feed said metal charge, each of said vibration mechanisms comprising a plurality of eccentric masses having their axes of rotation substantially orthogonal to straight lines parallel to the longitudinal direction, wherein each of said vibration mechanisms comprises at least a first plurality of said eccentric masses having their mass barycenters oriented in parallel directions to each other, and a second plurality of said eccentric masses having their mass barycenters disposed angularly offset with respect to the disposition of the barycenters of said first plurality of eccentric masses, said eccentric masses of each vibration mechanism being configured and kinematically actuated in reciprocal relation both between the eccentric masses of each plurality, and between said first and second plurality, and also between said vibration mechanisms, in order to determine, during use, a resulting centrifugal force substantially parallel to said longitudinal direction and a transverse component with respect to said longitudinal direction, substantially zero.
