First Claim
Patent Images
1. A vessel for use in a system for transferring molten metal, the vessel including outer walls, and:
- a cavity defined by the outer walls, the cavity for retaining molten metal;
an opening inside of the cavity;
a transfer chamber formed in the cavity above the opening, the transfer chamber comprising;
(a) a plurality of chamber walls, wherein at least one of the chamber walls is part of one of the outer walls of the vessel;
(b) an uptake section above, and in fluid communication with the opening, wherein the uptake section is configured to receive a rotor and rotor shaft, and configured to move molten metal upward and therethrough, and (c) an outlet above the opening, the outlet in fluid communication with the uptake section, wherein the outlet is configured so that molten metal reaching the outlet exits the uptake section through the outlet; and
an entrance to the uptake section and a tap-out opening positioned lower than the entrance.

Abstract
The invention relates to systems for transferring molten metal from one structure to another. Aspects of the invention include a transfer chamber constructed inside of or next to a vessel used to retain molten metal. The transfer chamber is in fluid communication with the vessel so molten metal from the vessel can enter the transfer chamber. A powered device, which may be inside of the transfer chamber, moves molten metal upward and out of the transfer chamber and preferably into a structure outside of the vessel, such as another vessel or a launder.
