Fixed molten aluminum degassing equipment

The utility model discloses fixed molten aluminum degassing equipment, which relates to the field of molten aluminum degassing and comprises a main body, a gas tank is arranged on one side of the main body, a stirring rod is arranged in the main body, and one end of the stirring rod penetrates through the outer wall of the main body and is connected with a main motor. The degassing mechanism is arranged, inert gas is injected into molten aluminum through the gas tank and the gas conveying pipeline, the main motor is started, the main motor works to drive the stirring rod to rotate, the injected inert gas is scattered into tiny bubbles, and hydrogen and included slag in the molten aluminum are removed in a diffusion and adsorption mode. Hydrogen diffuses from high-concentration and high-partial-pressure aluminum liquid to low-concentration and low-partial-pressure inert gas bubbles, the bubbles absorb the hydrogen and float upwards to take out the hydrogen in the aluminum liquid, the hydrogen content in the al
