[0001] The utility model belongs to the technical field of aluminum liquid degassing, and specifically relates to an aluminum liquid degassing device. Background Art

[0002] In the production and processing of aluminum ingots, the cast aluminum liquid needs to be degassed. Traditional equipment uses an aluminum liquid degasser for degassing. The inert gas (argon or nitrogen) is introduced into the aluminum liquid through the rotor. At the same time, the aluminum liquid is continuously stirred to turn the gas into discrete bubbles, and the impurities and gases in the aluminum liquid are adsorbed. This complex time is generally controlled at 5 to 10 minutes. The traditional aluminum liquid degasser uses a separate degassing chamber for degassing, but this degassing method is less efficient, and the degassing temperature will gradually decrease, resulting in a decrease in the subsequent slag suction efficiency.
