[0002] A chemical centrifuge is a mechanical device that uses centrifugal force to separate components with different densities in a mixture.

A first arc-shaped opening 210 is further opened at the lower end of the first restraint ring 203, and the first arc-shaped opening 210 is of an annular structure. A plurality of groups of second notches 211 are also arranged at the bottom of the inner groove 204, and second steel balls 212 are movably installed in each of the second notches 211.

[0024] Specifically, a chemical centrifuge is a mechanical device that uses centrifugal force to separate components with different densities in a mixture.
