Definitions

  • the present invention has for its object the provision of a cyclone type device for removing heavy solid impurities from a fluid containing a coarse mixture of light solid particles and heavy solid impurities.
  • the improved device comprises a main cyclone separator device, the upper extremity of which is provided with a tangential intake for the fluid containing the coarse mixture, and an axial outlet for the fluid and the light solid particles freed from the heavy solid impurities.
  • a main cyclone separator device Connected in coaxial relation to the lower end of the main separator, is an auxiliary cyclone separator.
  • the upper extremity of the auxiliary cyclone is provided with passage means which bring it into communication with the lower extremity of the main cyclone, and with a tangential inlet for a dilution fluid.
  • the lower extremity of the auxiliary cyclone comprises an outlet for the heavy solid impurities.
  • the said passage means between the two said cyclones include a radial annular passage which coacts with the tangential inlet to supply into the upper end of the auxiliary cyclone a mixture of fluid, part of the light solid particles, and all the heavy impurities from the main cyclone.
  • the radial annular passage is arranged at the level of the discharge end of the tangential inlet for the dilution fluid.
  • the said passage means also includes an axial passage through which passes fluid containing only light solid particles on its way upwardly from the auxiliary cyclone and into the main cyclone.
  • the axial passage is arranged below the radial annular passage.
  • FIG. 1 shows a separator device embodying the invention in elevational view and partly in section; and
  • FIG. 2 is a vertical cross-sectional view, on an enlarged scale, of the passage means between the main and auxiliary cyclones of the separator device.
  • FIGS. 1 and 2 of the application is suitable for carrying out the purification of paper pulp and includes a main cyclone having at its upper extremity a tangential inlet 11 through which is passed into the cyclone a coarse mixture of paper pulp composed of water, good light fibers, and heavy solid impurities such as fragments of bark and min eral particles.
  • the upper extremity of the main cyclone 10 is also provided with an axial outlet 12 for the final mixture of purified paper pulp composed of water and good light fibers. All of the heavy impurities, together with a part of the good light fibers and the water swirl in the direction of its entry, or clockwise, as shown in FIG. 1, toward the lower end of the main cyclone 10.
  • auxiliary cyclone 13 Connected to the lower end of the main cyclone 10 is an auxiliary cyclone 13 which is coaxial with the main cyclone and which is provided on its upper end with a tangential inlet 14 connected in a suitable manner to a source of dilution water.
  • the auxiliary cyclone 13 is connected to the main cyclone 10 by means of a nozzle-shaped member 17 which is provided at its upper end with a flange 19 that is secured by means of bolts 20 to a corre- 3,337,059- Patented Aug. 22, 1967 sponding flange 19 provided at the lower end of the cyclone 10.
  • the nozzle 17 is provided intermediate its ends with a male thread 18 which is screwed into the threaded upper ring-shaped end 13' of the cyclone 13.
  • the central opening 16 in the member 21 is in the shape of a tapered bore which is axial with and forms an extension of the tapered passageway in the nozzle 17, and together with the nozzle 17, provides an axial outlet for the purified paper pulp discharged by auxiliary cyclone 13.
  • the lower end of the nozzle 17 and the spaced distribution member 21 form between them a lateral or radial annular passage 15 which is arranged at the level of the tangential flow of dilution water coming into the cyclone 13 through the inlet 14.
  • the axial passage 16 is disposed below the annular passage 15 and is arranged almost wholly below the discharge end of the inlet 14.
  • the chamber 25 is provided with a transparent wall through which the impurities may be visually observed as an aid in controlling the rate of flow of water discharged into the cyclone: 13 through the inlet 14 so as to avoid any of the good fibers being carried away through the orifice 24.
  • the channel formed by the passage 15 in the liquid mixture discharging from the main cyclone 1t), enables the evacuation of the mixture of liquid and good fibers resulting from the purifying operation in the cyclone 13 into the main cyclone 10.
  • the purified mixture passes axially up through the passage 16 in the member 21 and through the passage in the nozzle 17 into the central vortex of the main cyclone 10, and with produced in such main cyclone, is then discharged from the device through the upper outlet 12.
  • a device for removing heavy solid particles from a fluid containing a mixture of light solid particles and said heavy solid particles comprising a main cyclone separator device, the upper end of which is provided with a tangential intake for the fluid containing the mixture and an axial outlet for the fluid and the light solid particles freed from the heavy solid impurities, an auxiliary cyclone separator coaxial with said main cyclone and arranged below the latter, the upper end of the said auxiliary cyclone being provided with a tangential inlet for introducing a dilution fluid in the same direction as the fluid mixture and the lower end thereof being provided with an outlet for the heavy solid impurities, and fluid passage means for bringing the upper end of said auxiliary cyclone into communication with the lower end of said main cyclone, and constructed to provide a fluid passageway extending vertically in axial relation to said cyclones, and an annular lateral fluid passageway located intermediate the upper and lower ends of said vertical passageway and in communication at its interior periphery with said vertical passageway,
  • said fluid passage means comprises a first nozzle-like member having an opening flared at its lower end, a second nozzle-like member having an opening flared at its upper end, and means connecting said second member in axially aligned relation to the lower end of said first member with the flared ends of the passages in said members in opposed relation, said annular lateral passageway being formed between the flared ends of the openings in said first and second members, and said vertical passageway being formed by such axially aligned openings in said first and second members.
  • a device in which said second member is located wholly below said first member and the axial opening in said second member forms an extension of the opening in said first member, said connecting means connecting the upper end of said second member to the lower end of said first member.
