Abstract
A vortex injection system for a metal recycling furnace a delacquering chamber and a melt chamber, and a molten metal flow channel running through each chamber. The system diverts a portion of the molten metal flow through a vortex bowl, after which that portion of the molten metal flow is then returned to the main molten metal flow. The vortex bowl has an insertion port through which scrap metal and other materials may be controllably injected into the molten metal flow.
Claims10
A vortex injection system for a metal recycling furnace, said furnace having a delacquering chamber and a melt chamber separated from said delacquering chamber, said furnace having a flow channel for a first flow of molten metal there through, a first section of said flow channel being exposed to said delacquering chamber, a second section of said flow channel being exposed to said melt chamber, said vortex injection system comprising:
- a. a vortex bowl adapted to receive a second flow of molten metal, said second flow comprising at least a portion of said first flow, said vortex bowl creating a vortex in said second flow;
- b. a first port for the flowing of molten metal into said vortex bowl, said first port receiving said second flow at least in part from one of said first section and said second section of said flow channel;
- c. a second port for the flowing of molten metal out of said vortex bowl, said second port directing molten metal from said vortex bowl into one of said first section and said second section of said flow channel;
- and
- d. a lift, said lift being adapted to controllably raise and lower said vortex bowl.
