Abstract:
A centrifugal separator comprising:a cylindrical bottomed main rotor body; a rack configured with multiple rack parts arranged along an inner circumferential surface of said main rotor body, said rack parts being linked together and able to move in radial directions of said main rotor body; said rack being formed in a ring shape; and at multiple locations in said rack, one slit is formed in a radial direction so as to completely cut and separate said rack, and other slits are made in radial directions which cut said rack while leaving a portion of an inner circumferential edge thereof; and said rack parts are formed so as to be divided by these slits; projections are formed on an upper surface of a first rack while concavities are formed on a lower surface of another rack; said other rack is mounted on said first rack; and said concavities in said other rack in an upper stage are mated with said projections respectively, in said first rack in a lower stage, thereby restricting said other rack in the upper stage to same turning direction as that of said first rack in said lower stage.
