Vacuumizing tubular centrifuge

A vacuumizing tubular centrifugal machine comprises a base, and a machine frame is fixed to the upper left portion of the base. The bottom plate is located above the base and fixed to the right side of the rack; the top plate is fixed above the rack; the shell is fixed on the right side of the rack through a bottom plate and a top plate; the shell is of a hollow structure, a heavy phase collecting device used for collecting heavy phase materials and a light phase collecting device used for collecting light phase materials are arranged on the upper portion in the shell, and the light phase collecting device is located below the heavy phase collecting device. The shell further internally comprises a rotary drum of which the interior is of a hollow structure; the rotary drum is communicated with the light phase outlet of the light phase collecting device and the heavy phase outlet of the heavy phase collecting device; the centrifugal machine can effectively complete centrifugal work of two components of PAO base
