The invention relates to an aluminium liquid stirrer. By adopting the helically stirring mode, the invention can make the anodic alloy on the bottom of material chamber move upward along the helical surface and mix with the injected aluminium liquid uniformly simultaneously, decrease the fluctuation of the three liquid surfaces of refined aluminum tank, and avoid the problem of refined aluminum quality depression caused by the liquid surfaces fluctuation; by manufacturing stirring head and stirring shaft adopting materials as carbon with fire resistant, stable performance and no-pollution to refined aluminum and sialon conbinded silicon carbide, the invention solves the problems of the existing aluminum liquid stirrer which can affect the quality of fine aluminum, reduces the energy consumption and equipment reparation; by adopting vibration-damping type spring auto-modulated legs, the invention avoids the heavy noise and nonsteady supporting caused by the poor axiality of power part and stirring part due to the unevenness of the tank edge plate surface.
