Patent number: 11939993Abstract: The present invention is directed to a molten metal pump comprising an elongated pumping chamber tube with a base end and an open top end. A shaft extends into the tube and rotates an impeller therein, the impeller rotates proximate the base end. The tube has a diameter at least 1.1 times the diameter of the impeller. The pumping chamber tube preferably has a length at least three times the height of the impeller. The base end includes an inlet and the top end includes a tangential outlet. Rotation of the impeller draws molten metal into the pumping chamber and creates a rotating equilibrium vortex that rises up the walls of the pumping chamber. The rotating vortex adjacent the top end exists the device via the tangential outlet.Type: GrantFiled: November 29, 2021Date of Patent: March 26, 2024Assignee: PYROTEK, INC.Inventors: Mark A.

Patent number: 8899932Abstract: According to one embodiment, a molten metal impeller is provided. It includes a generally cylindrical graphite body having a plurality of passages extending from a top surface to a side wall. A hub is formed in the center of the graphite body. A ceramic cap member is secured to the top surface of the graphite body. The cap member is comprised of a ring forming a central passage shaped cooperatively to overlap the hub and a plurality of vanes extending radially from the ring to an outer rim. The rim has a height between adjacent vanes which increases in the direction of intended impeller rotation. The rim further has a height which decreases from its radially outer most edge to an inner most edge.Type: GrantFiled: July 5, 2011Date of Patent: December 2, 2014Assignee: Pyrotek, Inc.Inventors: Jason Tetkoskie, Mark A.

Patent number: 8475594Abstract: A continuous galvanizing line uses a coating pot containing a molten zinc bath having bottom dross and further comprises a pump. The pump agitates the bottom dross so the bottom dross interacts with aluminum and converts to top dross, which can be removed without needing to stop the galvanizing line. A reaction vessel may also be used to provide a higher concentration of aluminum to react with the bottom dross.Type: GrantFiled: April 14, 2008Date of Patent: July 2, 2013Assignee: Pyrotek, Inc.Inventors: Mark A.
