Abstract
A centrifugal apparatus includes a centrifugal basket having a supporting base structure spaced below its bottom wall and fixed to the lower end of a vertical spindle to rotate the basket inside a casing surrounding the basket. The bottom wall of the basket has an opening therein about the spindle for discharge of centrifuged solids downwardly and then radially outwardly through the space between the base structure and the bottom wall. A basket valve member surrounds the spindle and is movable axially relative thereto between a position closing the basket opening and an open position spaced below the opening. A sleeve surrounds the spindle and is joined at its lower end with the valve member to position the valve member in its closed and open positions and further has an outwardly open annular channel at its upper end. A device for operating the valve includes a forked lever fulcrummed at one side of the spindle having arms straddling the spindle, each carrying on its end a roller confined in the channel. A motive device is mounted to the one side of the spindle for displacing the lever and thereby moving the sleeve axially so as to dispose the valve member in either of its positions.
