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.

First claim

What is claimed is:

1. A pumping device for placement into a pumping well for pumping molten metal, the pumping device including (a) a pump having a motor, a rotor and a drive shaft connecting the motor to the rotor, and (b) a portable refractory housing in which the molten metal pump is positioned; the portable refractory housing including: (i) an inlet, (ii) an uptake tube having a first section with a first cross-sectional area and a cylindrical second section with a second cross-sectional area, wherein the cylindrical second section is above the first section and the cylindrical second cross-sectional area is larger than the first cross-sectional area, and (iii) an outlet in communication with the second section, (c) the rotor being positioned in the first section, and (d) the pump being removable from the portable refractory housing without removing the portable refractory housing from the pumping well, and the portable refractory housing being removable from the pumping well, and; wherein the pump includes a first side and a mounting flange on the first side, the mounting flange for connecting to the platform, wherein the platform is on a top surface of the portable refractory housing.

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

3. The pumping device of claim 1 wherein the portable refractory housing has a rectangular outer surface.

4. The pumping device of claim 1 wherein the pump rests on a platform above the portable refractory housing so the rotor is positioned in the first section.

5. The pumping device of claim 1 wherein the pump includes a second side and a second mounting flange on the second side, the second mounting flange for connecting to the platform on the portable refractory housing.

6. The pumping device of claim 2 wherein the portable refractory housing includes a front side with one or more front flanges, and the launder has a first end proximal the pump and a second end distal the pump, 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 for connecting the launder to the portable refractory housing.

7. The pumping device of claim 1 wherein the portable refractory housing includes a bottom surface and the pump is not in contract with the bottom surface.

8. The pumping device of claim 1 wherein the launder has a top to retain heat.

9. The pumping device of claim 2 that includes a pumping well having a top surface wherein the launder rests on the top surface of the pumping well.

10. The pumping device of claim 1 wherein the outlet is horizontal.

11. The pumping device of claim 2 wherein the launder is horizontal.
