The invention relates to a secondary aluminum melt
impurity removal device which comprises a
smelting furnace, T-shaped rails, a moving box, a lifting block, a rotary
slag salvaging mechanism, a rolling frame mechanism and a
slag vibrating mechanism, the top of the
smelting furnace is open, the T-shaped rails are arranged on the two sides of the
smelting furnace, the moving box can slide along the rails, and the height of the lifting block is adjusted through a lifting air cylinder; the rotary
slag salvaging mechanism is slidably connected to the upper portion of the smelting furnace through a transverse rail rod, a rolling frame mechanism is arranged in the rotary slag salvaging mechanism and rotates by driving a gear to be meshed with a gear ring through a
servo motor B, the sections of a plurality of slag salvaging
sieve plates on the surface of the rolling frame mechanism are in an L shape, and the slag salvaging
sieve plates are used for salvaging impurities floating on the surface of molten aluminum and guiding the impurities into a slag containing disc on a mounting plate. Leaking holes are formed in the bottom of the slag containing disc to achieve
backflow of the molten aluminum, the slag vibrating mechanism automatically vibrates and cleans the slag salvaging
sieve plate through cooperation of a knocking rod and a spring so as to improve the cleaning efficiency, the whole device can accurately, automatically and efficiently remove impurities on the surface of the molten aluminum, the
safety risk of manual operation is reduced, and the
resource utilization rate is increased.
