Abstract:
Apparatus for charging a cupola foundry furnace having an upper stack and a lower furnace cupola having a preselected inside diameter comprising:a conveyor means for delivering charge materials to the furnace;an inverted conical trough, having an axis of rotation, for receiving the charge materials, the trough having an apex extending downwardly and further having an opening at the apex through which the charge material may flow, the opening sized to have a diameter substantially the same as the inside diameter of the furnace;the trough positioned above the furnace and in surrounding relation with the upper stack, with the opening positioned adjacent to and opening into the furnace;means for rotating the conical trough about its axis of rotation;a circular charge door wall with a bottom edge sized to abut against an inner surface of the conical trough above the opening; andlifting means for lifting the charge door to create a separation between the charge door and the conical trough to allow charge materials in the trough to flow into the furnace.
