Definitions

  • Our invention relates particularly to centrifuge bowls of the tubular type having a separating chamber with an imperforate peripheral wall and of considerably greater length than diameter and a balancin chamber adjacent to one end thereof, and t e leading object-of our invention is to afiord ready access to the balancing chamber. without disturbing the adjustment of the supporting head in the shell or the balance of the bowl assembly. Further objects of our invention are to prevent leakage through the top joints of the bowl; to provide readily adjustable means by which the efflux from the bowl may be controlled, and to simplify the construction and assembly of the parts by which the bowl is supported and the flow therefrom. controlled. 7 g
  • Bowls made in accordance with our invention have their supporting heads and shells permanently attached together, and the assembly is then given a proper running balance, and the relationship so established need not be deranged for cleaning the walls of the balancing chamber. 7
  • the balancing chamber is preferably formed by slots or sectors cut from the supporting head and covered by a detachable. balanced cap extending from the peripheryv inwardly to a ring dam controlling the discharge of heavier liquid.
  • the balancing chamber is separated from the separating chamber by a diaphragm preferably detachable therefrom' and having an outer edge approaching and but slightly-spaced from the inner wall of the shell; the diaphragm containingan axialopening or circular weir for the discharge of the lighter liquid from the separatingchamber to appropriate discharge passages.
  • the diameters of theeedges r weirs of the dams controlling the discharges of the separated constituents are suitably proportioned to secure the desired separation and separate 45 discharge of such constituents, and the provision of the balancing chamber and of the disk or diaphragm extending across a large portion of the diameter of the bowl permits the more eflectiveuse of the bulk. of the separating chamber and minimizes danger ofthe discharge of a constituent through the.

  • a frame 1 has an overhanging arm 2 containing a bearing providing a support for a pulley 3, driven by a belt 4, the pulley having suspended therefrom a flexible spindle 5, for supporting and rotating the bowl 6 having a removable bottom through which it is supplied from a tube 7 with substances to be separated.
  • the centrifugal bowl shell 8 which is long in proportion to its diameter and has an imperforate wall thickened at the top, contains the internal threads 9 adjacent to its upper-end and a shoulder or rib 10 below the termination of'the threads.
  • a The bowl head is formed from a hub 11 having a radial base from which segments are removed to form a balancing chamber comprising passages 12 spacing the radiating arms 13, which have threaded edges engaging the shell threads 9 to draw the bottomof the arms against the shoulder 10.
  • the passages 12 preferably extend from the hub to. the innersurface of the bowl so as to minimize obstruction due to lodgment of 100 heavy dirt on the outer wall and of floating dirt onthe inner wall and to. afford maximum access.
  • a light, balanced cap 33 containing a ces's 23v in which is screwed the threaded flange of a detachable disk or diaphragm 24 having its outer edge 25 spaced but slight- 1y from the inner wall of the shell.
  • the inner narrow edge 26 of the disk 24- forms a weir controllingingress of liquid to the recess 23 which communicates with longitudinal passages 27 in the hub.
  • These passages 27 are formed-by boring the hub and. then turning down the stem thereof so as to bisect the passages.
  • a tube 28 is then sleeved tightly on the stem to provide an outer'wall for the passages concentric with the axis of revolution and over which the discharging liquid flows with but small depth of crest.
  • the upper end of the stem is threaded for engagement of the coupling 29 to attach the bowl to the spindle 5.
  • the heavier constituents of the mixture fed to the bowl are discharged from the separating chamber between the edge 25 and the inner wall of the bowl into the balancing chamber 12 and discharged therefrom over the edge 22 into the detachable receptacle 30.
  • the lighter constituents are discharged through the axial opening in the disk 24,- through the recess 23 and passages 27 to the detachable receptacle 31.
  • the cap 33 may be detachedand'the walls of the passages 12 thoroughly cleaned without disturbing the relationship of the supporting head and the shell and without necessity for removing the bottom of the bowl.
  • the disk 23 may, if desired, be removed to permit access to the balancing chamber from the bottom of the bowl. It will be seen that each end of the balancing chamber is partly coveredby a detachable closure which when inplace con I trols the passage of liquid thereto and therefrom andwhich when removed affords free access to the balancing chamber.

  • a head comprising a hub having radiating members forming passages, and a detachable cap' having a detachable annular edge controlling eiiiux from said passages.
