Benefits of technology

This patent describes an insert used to transfer molten metal from a vessel. The insert is a closed structure with a rectangular outlet that is designed to easily accommodate a launder. Molten metal is forced into the insert through a first opening and rises to the top, where it passes through the rectangular outlet and into the launder, which is a vessel outside the insert. This design helps to transfer molten metal more efficiently and effectively than previous methods.

Problems solved by technology

Despite decades of use of systems and devices to transfer molten metal into launders, this refinement in design was not known.

Embodiment Construction

[0045]Turning now to the drawings, where the purpose is to describe a preferred embodiment of the invention and not to limit same, a system and insert according to the invention will be described. FIGS. 1-3 and 7 show a system 10 according to an aspect of the invention, and a vessel 1. Vessel 1 has a well 2, a top surface 3, a side surface 4, a floor 5, and a vessel well 6.

[0046]System 10 comprises a molten metal pump 20 and an insert 100. Pump 20 is preferably a circulation pump and can be any type of circulation pump satisfactory to move molten metal into the insert as described herein. The structure of circulator pumps is know to those skilled in the art and one preferred pump for use with the invention is called “The Mini,” manufactured by Molten Metal Equipment Innovations, Inc. of Middlefield, Ohio 44062, although any suitable pump may be used. The pump 20 preferably has a superstructure 22, a drive source 24 (which is most preferably a pneumatic motor) mounted on the superstr...

Abstract

A system according to aspects of the invention includes a pump and a refractory casing that houses the pump or is in fluid communication with the pump. As the pump operates it moves molten metal upward through an uptake section of the casing until it reaches a rectangular outlet wherein it exits the vessel. The rectangular outlet is configured to be connected to, or 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.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to and incorporates by reference: (1) U.S. Provisional Patent Application Ser. No. 62 / 849,787 filed May 17, 2019 and entitled MOLTEN METAL PUMPS, COMPONENTS, SYSTEMS AND METHODS, and (2) U.S. Provisional Patent Application Ser. No. 62 / 852,846 filed May 24, 2019 and entitled SMART MOLTEN METAL PUMP.BACKGROUND OF THE INVENTION[0002]As used herein, the term “molten metal” means any metal or combination of metals in liquid form, such as aluminum, copper, iron, zinc and alloys thereof. The term “gas” means any gas or combination of gases, including argon, nitrogen, chlorine, fluorine, Freon, and helium, which are released into molten metal.[0003]Known molten-metal pumps include a pump base (also called a housing or casing), one or more inlets (an inlet being an opening in the housing to allow molten metal to enter a pump chamber), a pump chamber of any suitable configuration, which is an open area formed within...
