Abstract

A system for removing molten metal from a vessel is disclosed. The system includes a pump and a refractory casing that houses the pump. As the pump operates it moves molten metal upward through an uptake section of the casing until it reaches an outlet wherein it exits the vessel. The outlet may be attached to a launder. Another system uses a wall to divide a cavity of the chamber into two portions. The wall has an opening and a pump pumps molten metal from a first portion into a second portion until the level in the second portion reaches an outlet and exits the vessel.

Claims

1. A device for moving molten metal out of a vessel that contain molten metal, the device for being placed inside of the vessel, the device including:

(a) An outer surface, a top with an opening, and a bottom for resting on an inner bottom surface of the vessel;

(b) a cavity in the device;

(c) a dividing wall in the cavity that divides the cavity into a first chamber and a second chamber;

the dividing wall having an opening that communicates with the first chamber and the second chamber;

(d) the first chamber being on a first side of the dividing wall;

(e) the second chamber being on a second side of the dividing wall;

(f) an outlet in fluid communication with the second chamber, the outlet being formed in a front wall of the device; and

(g) the dividing wall having a height, the opening having a height, and the outlet having a height, the height of the outlet being lower than the height of the dividing wall and greater than the height of the opening.

2. The device of claim 1 that further includes a launder attached to the outlet.

3. The device of claim 1 wherein the outer surface is rectangular.

4. The device of claim 1 that further includes a platform mounted on the top surface, the platform for connecting to and positioning a molten metal pump in the first chamber of the cavity.

5. The device of claim 4 that includes a first side and a mounting flange on the platform on the top surface of the first side, the mounting flange for connecting to and positioning a pump inside of the first chamber of the cavity.

6. The device of claim 2 that includes a front side with one or more front flanges on the front side, and the launder has a first end proximal the device and a second end distal the device, the first end of the launder having one or more launder flanges, wherein each of the one or more launder flanges aligns with one of the one or more front flanges on the front side of the device for connecting the launder to the device.

7. The device of claim 5 that includes a second side and a second mounting flange on the platform on the second side, the second mounting flange for connecting to and positioning the pump in the first chamber of the cavity.

8. The device of claim 1 wherein the device includes an inner bottom surface in the cavity.

9. The device of claim 2 wherein the launder has a top to retain heart.

10. The device of claim 2 wherein the vessel has a top surface and the launder rests on the top surface.

11. The device of claim 1 wherein the outlet is horizontal.

12. The device of claim 2 wherein the launder is horizontal.

13. The device of claim 1 wherein the cavity is one of the group consisting of rectangular and cylindrical.

14. The device of claim 1 wherein the dividing wall is vertical.

15. The device of claim 8 wherein the dividing wall extends to the inner bottom surface.

16. The device of claim 15 wherein the opening extends to the inner bottom surface.
