APPARATUS FOR TREATING FLOATING SLAG OF MOLTEN NONFERROUS METAL
Document Type and Number:
Japanese Patent JP2009293080
Kind Code:
A
Abstract:

To provide an apparatus for treating floating slag, which stirs and breaks down the floating slag produced in a melting furnace for a nonferrous metal, separates a melt of the nonferrous metal mixed in the floating slag from the floating slag with specific gravity and collects the melt with high efficiency, has superior heat resistance and durability, has a simple structure, and is suitable for a small melting furnace.

This apparatus includes: a floating slag treatment tank 1 which upwardly opens; a stirring blade 2 which is arranged in the floating slag treatment tank 1; a rotary driving means 3 of the stirring blade 2; and a tilting means 4 for tilting the floating slag treatment tank 1. A cylindrical part 11 standing straight is integrally formed in the middle position of the bottom wall 10b of the main body 10 of the floating slag treatment tank 1. A rotary driving shaft 5 is concentrically arranged in a non-contacting state through a heat insulation material 6 in the inside the cylindrical part 11. An installation base 20 of the stirring blade 2 is coupled to the top part 5a of the rotary driving shaft 5, which extrudes from the top end 11a of the cylindrical part 11, and the rotary driving means 3 is constituted so as to rotationally drive the rotary driving shaft 5.
