  • CENTRIFUGAL MACHINE Filed om. 27, 1927 2 sheets-sheet 1 Zll/ Mom/woz Patented Oct. 29, 1929 I UNITED STATES PATENT OFFICE LEO "'JONES, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE SHARPLES SPECIALTY COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF DELAWARE enrr'rnnsuenr. MACHINE Application -led October 27, 1927. Serial No. 229,020.
  • This invention relates to centrifugal machines and particularly to centrifugal machines for the separation of liquids, including semi-liquids, from solids.
  • the liquid constituent is usually discharged through a plurality of openings in the rotor and the solid constituent is discharged from the rotor at one or more definitepoints or is retained in the rotor.
  • the openings in the rotor for the discharge of liquid are made suiiciently narrow to prevent passage therethrough of particles of such size that they should not pass out with the liquid constituent, and greatly elongated in a direction at right angles to the axis of the rotor, such openings being in some instances a continuous narrow slot extending around the rotor.
  • liquid discharge yorifices of a centrifugal rotor that are sufiiciently small to hold back solid particles that should not be discharged with the liquid constituents quickly become clogged and there is no available method or mechanism for the prevention of such clogging or for the clearing of such orifices.
  • the liquid discharge pedals are made sufficiently narrow to prevent solid particles of such size that they should be retained with the solid constituent from being discharged through the openings with the liquid, but such openings are greatly elongated and I provide cleaners which extend into such elongated openings and I provide means for moving such cleaners with respect to the rotor.
  • liquid discharge openings of a centrifugal rotor which are of small enough dimensions to hold hack all particles that should he kept with the solid constituent of the mixture, are kept free of clogging or are cleared if theyr become clogged.
  • centrifugal machines for the separation of solids from liquids it is common to use some means for moving toward a discharge point the solids that are freed of liquid in the rotor, and it is known to construct the rotor ywith its walls diverging at an angle adequately great to cause the solids to progress under the action of centrifugal force and to use means for retaining them or controlling the advance of such solids.
  • Helical or spiral plates which move relatively to the bowl constitute a common form of such devices for preventing (or controlling the movement of the solids in the rotor.
  • the cleaners for the liquid discharge openings may be carried by these devices vention is applicable to centrifugal machines of various types in which a constiuent is discharged through a restricted orifice, regardless of whether there is a solid constituent that is retained'in the rotor or advanced by a means that moves it along or by centrifugal force under the control of a retarding means.
  • Fig. 1 is a 'vertical sectional' view, withl parts broken away, ofl one form of centrifugal machine embodying my invention
  • Fig. 2 is a plan view, with parts omitted, of the construction shown in Fig. 1;
  • Fig. 3 is a side elevation, with parts omitted, of the construction shown in Fig. 1.
  • the rotor A includes a frame consisting of a hub 10 having arms 11 which are 'advantageously'connected together by a rim 12.
  • the separating compartment of the rotor consists mainly of a series of rings 13 which areso mounted upon the frame, as by screws 14 that endless annular slots 15 are formed between the successive rings 13. These slots are made with a width sufliciently small to prevent passage Ftherethrough of allvparticles that are to be withdrawn from the liquid, but during rotation of the rotor the liquid will pass therethrough and cannot flow toward either end of the rotor without eventually passing through one of the slots.
  • the rings are cut away as at 16 in order that the liquid will not have to pass through a restricted opening of too great a length and in order to provide larger passages 17 for the flow of liquid.
  • the cleaning of the liquid passages is facilitated.
  • Liquid discharged through the passages 15 will be collected in the compartment 18 from which it will flow through the spout 19.
  • This compartment may be constructed in any suitable manner.
  • the hub 10 thereof is connected by key 21 to a hollow shaft 20 that is supported in any suitable bearing 22 and rotated in any suitable manner.
  • Shaft 27 extends through shaft 20 and is connected by key 28 to hub 24 of member 23.
  • blades 29 with respect to the inner surface of the rotor Iand the helical shape of those blades will cause the solid material to be fed toward the discharge point for solid material which in the construction shown is at the top of the rotor, and the solid material will pass over the auxiliary 'rim 40 and it will be collected in a chamber 41 of suitable construction, only vparts of which are indicated. If the angle of divergence of the walls of the rotor is so 'great that centrifugal force imparts to the solid material a tendency to slide toward its point of discharge, the blades 29 will restrain ⁇ Vsuch sliding and relative motion of those blades with respect to the rotor will permit the solid material to advance under control toward its point of discharge.
  • the relative motion with respect to the rotor of the means for causing or controlling the advance of solids toward their point of discharge will effect a relative motion of the blades 32 with respect to the rotor and those blades will move in the liquid discharge slots 15 and prevent them from becoming clogged or clear them if they should become clogged.

Centrifugal force causes the liquid provided with liquid discharge openings, means movable relatively to said rotor during rotation thereof for regulating movement of solids therein, and cleaners for said openings and operated by said regulating means and leaving a major portion of said openings unobstructed.

  • a centrifugal machine comprising a rotor mounted for rotation and having its walls provided with liquid discharge openings comprising elongated slots, a support within the rotor and mounted for movement relatively thereto during rotation of the rotor, and slot cleaners carried by said 'support and maintained in operative relation with respect to said slots by centrifugalforce.
