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. Bright, Jason Tetkoskie, Richard S. Henderson, Herbert L Ritchie, Jr., Jorge A. Morando

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. Bright, Richard S. Henderson

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. Bright, Gregory C. Becherer, Robert L. Grodeck

Patent number: 7278824Abstract: A molten material pump includes an impeller housed within a base member of the pump. A plurality of grooves are defined in a peripheral sidewall of the impeller for either drawing a molten material into the base member's chamber or pushing molten material out of the base member's chamber. The impeller is rotated by a rotatable shaft connected to an upper surface of the impeller. The rotatable shaft includes a non-circular shaped lower end dimensioned to be received within a cooperating opening in the impeller. The molten material pump further includes a connecting assembly for interconnecting components of the molten material pump. The connecting assembly includes a first mounting member attached to a first pump component that is dimensioned to be fitted within a cooperating recess of a second mounting member attached to a second pump component. In another embodiment of the invention, a stub shaft connects an upper shaft portion of the shaft to the impeller.Type: GrantFiled: December 14, 2004Date of Patent: October 9, 2007Assignee: Pyrotek, Inc.Inventors: George S.

Patent number: 6921023Abstract: A self-contained water display. The water display includes a cylindrical fountain housing. The fountain housing contains at least one fountain nozzle extending vertically upwardly, and at least one pump adapted to supply water to the nozzle with sufficient volumetric throughput to cause a vertical water stream to be ejected therefrom. A vertically disposed transparent cylindrical cover surrounds the fountain housing with the fountain housing being located in a lower portion of the transparent cylindrical cover. The transparent cylindrical cover has a height above the nozzle that is at least as great as the height of the vertical water stream generated by the fountain nozzle. The fountain housing and the lower portion of the transparent cylindrical cover are surrounded by a lightweight shell simulating a rock. The water display may include a transparent aquarium surrounding the fountain housing and transparent cylindrical cover.Type: GrantFiled: September 15, 2003Date of Patent: July 26, 2005Inventors: Mark A.
