Abstract
A device includes a molten metal pump and a metal-transfer conduit. A clamp may be used to attach the metal-transfer conduit to the pump. The pump has a pump base including an indentation configured to receive the metal-transfer conduit and align the pump outlet with the transfer inlet. The pump outlet may be formed in the indentation and preferably near the center of the indentation in order to better align with the transfer inlet. As the pump operates it moves molten metal through a pump outlet that is in communication with a transfer inlet in the metal-transfer conduit. The molten metal enters the transfer inlet, moves upwards in a passage in the metal-transfer conduit, and out of a transfer outlet.
Claims17
A device for transferring molten metal, the device comprising:
- (a) a pump configured for pumping molten metal, wherein the pump comprises (i) a pump base including a pump chamber, a pump outlet, and a discharge extending from the pump chamber to the outlet, (ii) a rotor in the pump chamber, and (iii) a front side that includes an indentation, wherein the pump outlet is positioned in the indentation;
- and
- (b) a metal-transfer conduit having a top portion and a bottom portion, a transfer inlet, a transfer outlet, and a passage extending from the transfer inlet to the transfer outlet, wherein the bottom portion of the metal-transfer conduit is positioned in the indentation and the transfer inlet is juxtaposed and in fluid communication with the pump outlet,
- wherein the metal-transfer conduit has a front surface having a first width, and a rear surface on which the transfer inlet is positioned, wherein the rear surface has a second width, and the second width is less than the first width;
- and the metal-transfer conduit further includes two side surfaces that connect the front surface to the rear surface, wherein each of the two side surfaces is angled.
