Abstract

938,324. Centrifugal separators. WESTFALIA SEPARATOR A.G. June 25, 1962 [June 26, 1961], No. 24400/62. Class 23. In a separator comprising a bowl having sludge outlets 7, Fig. 1, controlled by a piston valve 4 axially displaceable by the pressure difference of a control liquid supplied to opening and closure chambers 1, 2, control means are provided for varying the free surface of the control liquid with respect to the bowl axis in either the opening or the closing chamber thereby varying the pressure differential exerted on both sides of the piston valve. The control liquid is fed to the chambers 1, 2 through a conduit 18 and channels 19, 20. Chamber 2 is connected through a channel 8 to a chamber 9 into which extends a scoop pipe 10 may be radially displaced or pivoted to shift the free surface of the control liquid in chamber 2 so as to adapt the liquid closing pressure to the specific weight of the sludge being separated. In a modification the scoop pipe extends in a chamber in communication with the opening chamber 1. In a further modification, Fig. 2, a radially displaceable overflow pipe 11 is provided in the bottom of the separator drum in communication with the chamber 2 through a channel 14. Alternatively the pipe 11 may open directly in the chamber 2.
