The utility model relates to a large-capacity continuous centrifuge, which comprises a centrifugal unit and an electric motor; wherein, a crankshaft arranged on the electric motor penetrates the centrifugal unit; the centrifugal unit is a frustum-shaped annular centrifugal tank in which an annular sample tank is arranged; light-phase sample-discharging outlets are symmetrically arranged on the outer wall, which is opposite to the crankshaft, of the centrifugal tank; the other ends of light-phase sample-discharging tubes arranged at the light-phase sample-discharging outlets are arranged in an upper annular sample-receiving tank arranged outside the centrifugal tank; heavy-phase sample-discharging outlets are symmetrically arranged on the bottom, which is opposite to the crankshaft, of an annular sample tank; the other ends of heavy-phase sample-discharging tubes arranged at the heavy-phase sample-discharging outlets are arranged in a lower annular sample-receiving tank arranged under the sample tank; upper and lower support bars are respectively arranged between the upper and the lower annular sample-receiving tanks and the lower side of the electric motor; and a sample inlet tube and an organic solvent inlet tube are arranged on the upper side of the annular sample tank. The utility model, which can continuously centrifugate large capacity liquid, has the advantages of simple structure, convenient operation, good separation effect, and the like.
