Abstract
A centrifuge apparatus having an external movable member to close the outer end of a fixed width peripheral discharge opening which may be partially deformable to effect such closing.
Claims7
A centrifuge comprising:
- an elongated shaft member rotatable about the longitudinal central axis thereof;
- a bowl member having formed sections rigidly secured to axially spaced portions of said shaft member, respectively,
- said formed sections extending radially outwardly of and circumferentially encompassing said central axis to form a chamber in conjunction with said shaft member,
- said formed sections having a discharge opening of a fixed axial configuration between radially outer peripheral portions of said formed sections for discharging a centrifuged material,
- means for introducing a slurry into said bowl member,
- said bowl member having means for discharging an effluent constituent of said slurry,
- a ring structure encompassing the radially outermost extent of said peripheral portions at least a portion of which includes a resilient member forming one side of the material flow path from said discharge opening,
- actuator means having relatively movable parts with one of said parts being secured to one of said formed sections and the other of said parts being cooperable with the resilient portion of said ring structure to displace at least a portion of said ring structure with respect to said radially outermost extent, and
- said actuator means being selectively and independently operable to move said other of said parts and displace at least said portion of said ring structure to selectively and independently open and close said discharge opening.
