The invention relates to a drive-type
centrifugal extractor for use in chemical industrial operation, which belongs to the chemical
processing equipment field, comprising a
mixing tank, a rotary drum, and a motor. The
mixing tank and the rotary drum are coaxially mounted on the
machine base, the
mixing tank covers the rotary drum in reverse to make the rotary drum in the mixing tank, and the rotary drum is linked with the motor via a rotating shaft. Between the outer shell of the mixing tank and the outer shell of the rotary drum are arranged a heavy-phase collection ring and a light-phase collection ring, a heavy phase outlet is arranged on the mixing tank outer shell between the heavy-phase collection ring and the upper cover of the mixing tank, and a light phase outlet is arranged on the mixing tank outer shell between the heavy-phase collection ring and the light-phase collection ring, and on the mixing tank outer shell between the light-phase collection ring and the bottom of the mixing tank are arranged two inlets. In the invention, the motor and the transmission parts are provided on the bottom of the main
machine, which makes the weight of the
machine shift downwards to the bottom. The
centrifugal extractor is provided with compact structure, stable operation, and more convenient utilization and maintenance, and the rotary drum may not be disassembled when replacing phase barrage, thereby the
centrifugal extractor is suitable for use in large-scale equipment.
