0, flows into the first stage feed section 14a through the opening 62, and falls through the opening 46 into the mixing section 18. The light liquid and heavy liquid are mixed in the gap between the wall surface of the mixing section 18 and the separation rotor 16 that rotates at high speed. The mixed liquid is sucked by the separation rotor 16, and the centrifugal force separates the heavy liquid into heavy liquid aq and light liquid org. The heavy liquid collector 10a collects the heavy liquid and discharges the liquid from the heavy liquid outlet 56 to the outside of the casing. On the other hand, the light liquid is discharged beyond the heavy liquid layer 40 located at a lower position than the heavy liquid base 38, and is collected by the light liquid collector 12a. This light liquid flows down through the opening 32 and the passage 66, and flows through the opening 68 into the n-th stage feed section 14b. Then, it is mixed with the heavy liquid from the m-th stage heavy liquid collector 10c and separated. In this way, the heavy liquid and light liquid flow in opposite directions while being mixed and separated at each stage.

It has an integrated structure in which mixing parts each housing the lower parts of a plurality of separation rotors located so as to pass through them are distributed below the feed part, the heavy liquid collector part, the heavy liquid collector part, and the feed part. The inside of the centrifugal extraction stage is partitioned by a partition wall for each separation rotor, and each centrifugal extraction stage is connected by an opening provided on the lower surface of the collector part and a passage formed in the partition wall. Dexterous multi-stage casing.
