Definitions

  • cyclones have been principally used in the separation of solid particles from gases. or to concentrate or thicken suspensions of solid particles in liquids.
  • Driessen et al. Serial No. 664,320, filed April 23, 1946, Patent No. 2,543,689, issued February 2'7, 1951, there is disclosed a process for separating solid particles of difierent grain size and diflerent specific gravity using a cyclone, the process involving the mixing of the particles to be separated with a liquid carrier and with relatively fine particles of a specific gravity higher than the specific gravity of separation.
  • This type of cyclone comprises essentially a shell in the form of an elongated frustum of a relatively steep cone.
  • the object of the present invention is to provide a cyclone with an improved form of vortex chamber which greatly raises the eificiency of the separating action in the case of particles of different grain size and specific gravity.
  • the vortex chamber is made of generally conical form with the inner surface thereof in axial section defining an included angle which progressively increases toward the apex, providing a concave internal longitudinal contour.
  • the progressively increasing angle may be defined by successive conical frusta of increasing flatness toward the apex, or the inner surface of the vortex chamber may be smoothly curved, as the sides of a bowl, adjacent the apex opening.
  • the inner surface of the cyclone generally will define the outer envelope of the bod or mass rotating within the cyclone.
  • Figure 1 is an axial section of a cyclone whose shell comprises a series of conical frusta
  • Figure 2 is a partial section like that of Figure 1 showing the attainment of concavity curvilinearly instead of by broken straight lines as in Figure 1, and More 3 is a view like that of Figure 2 showin a modification.
  • the cyclone shell is of generally conical form and comprises a cylindrical portion I surmounting a series of conical frusta 6, l and I.
  • the cylindrical portion I is provided with a cover 8 having an axial discharge opening in.
  • Reference numera1 ll designates a feed pipe disposed tangentially to section 6 and debouching into the interior thereof through an opening I2.
  • Section 6 is a frustum of a cone whose apex angle is 20.
  • Section 1 has an angularity of and section 8 an angularity of and defines an apex opening l3 which is rimmed outwardly by a discharge nozzle H.
  • the terminal section 8 may have an angularity anywhere from 60 to 90 or over.
  • section 6 may have a diameter of 60 mm., base opening III a diameter of 18 mm., with inlet opening I 2 equivalent to 18 mm. in diameter.
  • Section 6 may have a bottom diameter of 40 mm. and an altitude of 118 mm.;
  • section 1 may have a bottom diameterof 25 mm. and an altitude of 19 mm.; and
  • section 8 may have an apex opening 7 mm. in diameter and an altitude of 9 mm.
  • the suspension was fed at the same velocity in both instances but less and less of the relatively fine particles was added so that the specific gravity of the suspension was progressively lowered.
  • the apex end of the cyclone shell may be longitudinally convexed to the discharge opening with further improved results.
  • the body of the cyclone is like that of Figure 2 except that at the apex end, the concavity merges into an internally convexly curved funnel-like spout l5 which defines the discharge opening.
  • any element of the shell has at its apex end a concavity which merges smoothly into a terminal convexity. This same form of spout could be provided with the shell of Figure 1.
