Abstract
Centrifugal separator for separating a specifically lighter component via a discharge passageway (14) therefor, a specifically heavier component via a discharge passageway (5a, 10, 11, 13) therefor and collection of a solids component in a solids collecting zone (29). Passageways for discharge of solids are provided at the radial periphery of the drum and valve means are provided for periodically opening of the solids discharge passageways. The invention provides automatic control means for actuation of the valve means for discharging of solids. The control means comprises control fluid passageway (3a, 6, 7, 9, 15) having an inlet (3b) disposed outwardly of the inlet (5b) of the specifically heavier fraction discharge passageway (5a), and including a control chamber (7), and bore (15) which conveys the control fluid to the separated specifically heavier fraction for discharge therewith. A pressure switch (17) is exposed to the flowing control fluid and upon interruption of flow of control fluid, due to accumulation of solids at the level of the control fluid passageway inlet (3b), the pressure switch actuates control means for opening of the solids discharge passageways.
