Definitions

  • This invention relates to separators for treating liquids and suspensions of solids in liquids, and more particularly for treating paper pulp, in which the material to be treated is injected tangentially at high speed through an inlet tapering to a reduced and substantially rectangular crosssection into a vortex vessel of circular section from which the puried material emerges in an upward direction while the separated impurities are allowed or into a space sheltered from the swirl of the vortex chamber.
  • Separators of this kind have been described in my application Serial No. 346,781.
  • a primary purpose of this invention is to enable the separator to work at high efficiency over a wide range of through-flow by maintaining the speed of injection substantially constant notwithstanding variations in the through-flow.
  • a sub.. sidiary purpose is to enable manufacturers to vsatisfy by a small range' of separators demands for separators for different through-flows extending overa wide range.
  • one object of the invention is a vortex separator of the type above for constricting the inlet channel either in the inlet nozzle by which the material treated is injected or in the circular duct which continues the inlet nozzle and in formed. It is important that such means shall not disturb the formation of the vortex, as would occur if its outer layers should be'directed inward across the vortex ow; the outer wall of the nozzle should therefore be con- 'tinuous with the outer wall of the vortex-formingv duct and constriction should be effected by modiiicationV of another wall bounding the inlet channel.
  • a further object of the invention is a separator in which; the area of cross-section of -the inlet channel at its smallest is controlled automatically in accordance with the through-dow. More specifically, an. object of the invention is a vortex separator with means for constricting its inlet channel governed by a float adjacent to a Weir in one of the conduits by which the material treated is led to and from the separator.
  • variable inlet for the purpose of the invention.
  • Figures 1 and 2 are elevation and plan respectively, each partly in section, of the head of a vortex separator having both a variable inlet and a variable outlet;
  • Figure 3 is an elevation in section on the line 3-3 of Figure 4, and Figure 4 a plan in section on the line 4 4 of Figure 3 of a modified construcion;

  • FIG. 10 is a sectional plan of a third form of variable inlet, in which, as in the constructions so i'ar mentioned, the constriction ail'ects the radial depth of the inlet:
  • Figure 11 is a plan from underneath, in section on the line II-II of Fig-ure 12, and Figure 12 is an elevation in section on the line I 2-I2 of Figure 11, (the tangential inlet however being shewn in axial section.) oi' a, fourth form of variable inlet. l
  • Figure 13 is an elevation partly in section of a fifth form of variable inlet which, like the fourth, is variable in effective axial depth.
  • Figure 14 is a diagram illustrating the auto- Amatic control of a variable inlet, or inlet and outlet.
  • This sleeve forms a portion of the outlet and fits and iills the cylindrical and concentric portions of the upper part of the vessel formed in the head 2 yabove a circumferential groove in the sleeve.
  • This groove is of increasing radial depth and of the same axial depth as the tangential inlet nozzle 3; this is annular at its'top and thereafter helical.
  • the groove. deepens to the full radial thickness ofthe sleeve, which therefore ends in a helical tail 'I wrapped around the outlet pipe.
  • Figures 1 and 2 also show a means for adjusting the effective cross-sectional area of the outlet pipe 4 in correspondence with .and simultaneously with the adjustment of the inlet.
  • plunger I6 is mounted to slide in a gland I8 in the wall of the outlet pipe 4. There is attached -to it a pin carrying a roller I1 located in a cam slot I8 in a cam arm 8.

  • the tail piece I is deepened wherenecessary to prevent any part of the inlet port of the head being uncovered clear of the sleeve 6 in the end position of the latter.
  • the turning of the sleeve also causes the cam I9 to advance the plunger I 5 into or withdraw it from the outlet pipe 4 as the cross-section of the inlet is diminished or increased.
  • The4 sleeve 5 is set on'ce and for all by the manufacturer to correct for any tolerance in manufacture affecting the through-flow, or to adjust the through-flow to a particular value within a limited, range, and is then xed in position and the parts bolted up tight.
  • the outlet pipe proper 4 ends at its flange and is prolonged by the inlet-regulating sleeve 23'; the upper part of the sleeve is. as before, of a diameter equal to that of the head and in this part is formed a helical groove as already described.
  • the bore of of the outlet pipe at the sleeve, equa-l to that the top. is constricted at 25 with an enlarged and tapered end 26 is mounted to slide in a gland 2l in the outlet pipe by a bell-'crank lever 28 pivoted on a bracket 29 on the outlet pipe and rocked by the action of the cam I9 upon a roller 3I on its end.
  • the form of the sleeve 23 is further illustrated ered by the sleeve.
  • Figures 6 to 9 show an alternative means of varying the cross section of the outlet.
  • the two bars take .up such a relative position as is shown in 'Figs'. 8 and 9, in which the free area of bore of the outlet pipe is reduced substantially to the minimum.
