CENTRIFUGAL SEPARATOR Filed March 21, 1942 INVENTOR Leo Djones.
A TTORNE Y Patented May 30, 1944 UNITED STATES PATENT: OFFICE,
CENTRIFUGAL SEPARATOR Leo D. Jones, Philadelphia, Pa., assl'gnor to The Sharples Corporation, Philadelphia, Pa., a corporation of Delaware Application March 21, 1942, Serial No. 435,601 1 3 Claims. (Cl. 210-68) The present invention pertains to centrifugation, and includes a process and machine for dehydrating solids and separately disthe art of quence of rapid intermittent movements from a centrifugal rotor in which they are dehydrated.
- Such schemes have been subject to the objection that they entail a high degreeof friction between v the rotor toward the discharge point without the use of complicated apparatus and without any relative rotation between the ,surface of the rotor along which the solids mo'g'e and the tool by which they are discharged.
These results are attained by providing a disc which oscillates about axes at right angles to the axis of rotation of the rotor while rotating with the rotor. This oscillation is preferably in the nature of a compound movement providing a wobbling of the periphery of the disc for causing longitudinal movement of the solids, and is produced by a special mechanical movement as described hereinafter.
Further features of the invention, and the de- 7 wall of the rotor, after passing through the screen 29.
A casing Ii surrounds the end of quill it re mote from the rotor l0, and this casing is secured to the outer casing 16 of a speed reducing mechanism 30. This speed reducing mechanism includes a high speed shaft i1 and a low speed shaft i8, projecting from opposite ends of the casing. Any standard form of speed reducing mechanism designed to receive power from a high speed shaft such as I1 and transmit that power to a low speed shaft such as l8 may be in the practice of the invention.
A shaft i9 is mounted in a self-aligning bearing 20 on the axis of the'rotor ill, and a flange '2! is secured to the end of the shaft 19 withn the rotor. A disc 22 designed to effect discharge of solids from the rotor is secured to the flange 2|, and the outer circumference of this disc lies in close proximity to the screen 29, with sufficient clearance to permit oscillating movement of the disc relatively to the screen in 'a manner which will be described hereinafter.
A conical feed tube 23 is secured to the disc 22 by a number of rods 24. A pipe 25 is provided for feeding mixtures of liquid and solids to the rotor, and the inner end of this pipe projects into the conical feed tube 23.
The. end of the shaft is isconnected to a ball 26 mounted for free rotation with respect to a socket 21 eccentrically mounted upon shaft II, the self-aligning bearing connection between ball 26 and its. socket permitting free rotation of shaft IS with respect to socket 21 and movement of the axis of this shaft as described hereinafter.
The quill I i and other rotating parts derive their power from pulley 28, as will be evident from the following, description of the operation of the machine,
. In operation, power is applied to the drive pulley 28, and this causes rotation of the quill II and rotor Ill. The mixture to be treated is then passed tothe rotor, being passed into contact with the screen 29 through the annular passage defined by the feed tube 23 and disc 22. The
