Patent number: 11391293Abstract: Embodiments of the invention are directed to a rotor for a molten metal pump and a molten metal pump including the rotor. The rotor has a main body and a top comprised of a material that is at least twice as hard as the main body. The top, among other things, may form a first portion of each rotor blade wherein the first portion directs molten metal into a pump chamber or other structure in which the rotor is mounted.Type: GrantFiled: April 29, 2020Date of Patent: July 19, 2022Assignee: Molten Metal Equipment Innovations, LLCInventor: Paul V.

Publication number: 20220213895Abstract: A molten metal rotor receives and retains an end of a molten metal rotor shaft. The rotor shaft has one or more projections at the end received in the rotor. The rotor has an inner cavity, a top surface with an opening leading to the inner cavity, and at least one abutment. The opening includes one or more portions for allowing each projection to pass through the opening and into the inner cavity. The rotor and/or shaft are then rotated so at least one of the outwardly-extending projections is under the top surface of the rotor and is against an abutment. A molten metal pump, rotary degasser scrap melter or other device used in molten metal may utilize a rotor/shaft combination as disclosed herein.Type: ApplicationFiled: March 24, 2022Publication date: July 7, 2022Applicant: Molten Metal Equipment Innovations, LLCInventor: Paul V.

Publication number: 20220080498Abstract: The invention relates to systems for transferring molten metal from one structure to another. Aspects of the invention include a transfer chamber constructed inside of or next to a vessel used to retain molten metal. The transfer chamber is in fluid communication with the vessel so molten metal from the vessel can enter the transfer chamber. A powered device, which may be inside of the transfer chamber, moves molten metal upward and out of the transfer chamber and preferably into a structure outside of the vessel, such as another vessel or a launder.Type: ApplicationFiled: November 29, 2021Publication date: March 17, 2022Applicant: Molten Metal Equipment Innovations, LLCInventors: Paul V. Cooper, Vincent D. Fontana

Publication number: 20220025905Abstract: A vertically-elongated member, which is preferably a support post used in a molten metal pump, includes a ceramic tube and tensioning structures to add a compressive load to the tube along its longitudinal axis. This makes the tube less prone to breakage. Another vertically-elongated member, such as a support post, includes one or more reinforcement members to help alleviate breakage. A device, such as a pump, used in a molten metal bath includes one or more of such vertical members.Type: ApplicationFiled: October 7, 2021Publication date: January 27, 2022Applicant: Molten Metal Equipment Innovations, LLCInventor: Paul V.
