Abstract

1395044 Centrifugal separator BELOIT CORP 26 April 1972 [28 May 1971] 19485/72 Heading B2P A centrifugal separator, for separating intermixed solids and liquid comprises a rotatable hollow bowl 10 having its inner diameter decreasing towards one end with a solids discharge opening 12a at that end and a liquid discharge opening 13a at the other end; a helical conveyor scroll 18, 19 coaxially supported within the bowl for rotation at a controlled speed different from that of the bowl for moving solids towards the discharge openings 12a; feed means 20, 21 within the bowl for supplying a solids-liquid mixture thereto; a variable speed drive means 29 having an output shaft 39 connected to the scroll 18, 19 and having first and second input shafts 41, 43 respectively; a main drive motor 27 connected to the bowl 10 through the first input shaft 41 for driving the bowl at a predetermined constant speed; a hydraulic pump 35 driven by the motor 27; a hydraulic motor 34 connected by fluid-carrying lines 36 to the pump 35 to be driven thereby and drivingly connected to the second input shaft 43 of the drive means 29; and means 37 for controlling the relative hydraulic fluid flow displacement between the pump 35 and the hydraulic motor 34 so that the speed of the shaft 43 is controlled to control the speed of the scroll 18, 19 in relation to the speed of the bowl 10. The motor 27 drives the first input shaft 41 via a fluid coupling 28 and a V-belt drive 26. The drive means 29 is a planetary gear reducer comprising planetary gears 32 connected to the output shaft 39 and sun gears 31 and 33 respectively connected to the first and second input shafts 41, 43. The control means 37 is a valve which is incorporated in the fluid-carrying lines 36 and controls the hydraulic fluid flow directed between the pump 35 and the motor 34 so that the pump may operate as a motor and the motor as a pump. A pressure sensing valve 38 is connected to the lines 36 to reuse the output hydraulic pressure of the pump 35 and is also connected to a feed control valve 22 to regulate the feed to the bowl.
