Definitions

  • This invention relates to a vortex separator for separating heavy particles from paper making stock and other liquid slurrles.
  • the invention relates more particularlyto a vortex separator of the type wherein a whirling motion initially imparted to the stock as it enters a separating chamber is relied upon to set up deslred conditions of centrifugal force for effecting separation of the heavy particles therefrom.
  • the present invention provides a vortex separator wherein the stock ilows in a substantially straight line from the inlet of the separating chamber to the outlet across an annular or circumferential discharge passage or ⁇ gap of substantial length within the separating chamber under controlled conditions such that heavy ⁇ particles are discharged through this passage into the interior of the separating chamber while the resulting clean stock ows directly to the outlet from the chamber.
  • the invention provides operating conditions such that the rate of now of the clean Stock leaving the separating chamber may be decelerated after the stock crosses the discharge passage, thus further assuring effective separation of the heavy particles and minimizing the carrying capacity of the clean stock for reject material.
  • conduits rectly from the inlet conduit and in substantially straight line flow.
  • the adjacent ends of these conduits are spaced from each other to leave an annular or circumferential discharge passage therebetween of substantial axial extent which opens into the interior of the separating chamber, and a core is provided which extends axially through this passage between the conduits.
  • One ofthe conduits includes a portion of substantial length which is positioned within the chamber but is of substantially smaller diameter than the chamber to provide therein an annular portion 0r space surrounding the annular discharge passage and extending downwardly below the level of this passage within the chamber.
  • the bottom of the separating chamber is provided with a horizontally arranged screw conveyor which is motor driven at one end and isprovided at the other end with an outlet having a counterweighted closure.
  • This conveyor collects reject material settling to the bottom of the separating chamber and conveys it to its outlet until there is sufiicient accumulation vof reject material at the outlet to force open When this occurs, the reject material is discharged as a damp sludge comparable in consistency to wet sand or gravel, but since the accumulated, slug of material between the conveyor and the outlet remains in place, it effectively seals against loss of liquid through the outlet except for the relatively small amount of liquid which adheres to the reject particles.
  • Another object is to Yprovide a vortex separator wherein the direction and rate of now through the separating chamber of the stock to be cleaned areV readily controlled and maintained under conditions of low turbulence which effectively minimize the carrying capacity of thestock for heavy particles and thus facilitate efficient operation of the device with low power requirementsr to give resulting economy of operation and maintenance.
  • FIG. 1 is a perspective view of a vortex separator in accordance with the invention
  • Fig. 2 is a diagrammatic View of the separator on a larger scale than Fig. 1 and with portions of the casing broken away to illustrate details of internal construction and operation;
  • Fig. 3 is a top plan view of the device.
  • the main base I E supports a cylindrical casing il which encloses a separatingchamber I2 oi substantial volume and vertical extent.
  • the casing ll is mounted on base III by means of a nange I3, and it includes an outlet conduit i5 which projects upwardly for a substantial distance within chamber I2 and is curved forwardly through the front of the casing for attachment at It to a suitable discharge pipe.
  • An inlet conduit 2li is mounted on the upper end of casing I I by means of a flange 2 I, and it includes a tangentially arranged inlet connection 22 at its upper end.
  • a helix comprising a core 25 and a helical vane 26 is vmounted within the inlet conduit 2D by means of a flanged upper end portion 2l and a twopiece clamping ring 28V provided with an-annular gasket 29.
  • annular space 33 is provided within chamber I2 which includes an upper portion surrounding the discharge gap 30 and a lower portion continuing downwardly therefrom around conduit 20 to the lower end of the chamber.
  • the core 25 of the helix in the inlet conduit 2B is of increasing diameter in the direction of flow through conduit 20 to provide a progressively decreasing cross sectional flow area through the inletconduit and thus to effect acceleration of the rate of flow of the incoming stock.
  • a cylindrical portion which extends downwardly below vane 26 and completely through the interior of the discharge gap 3l) into the upper end of the outlet conduit I5.
  • the base I includes a tapered throat portion 35 which provides the bottom for separating chamber I2, to receive reject material settling in the chamber, and a cylindrical passage 35 extends horizontally through the base below and in com- 35.
  • a screw conveyor All is mounted in the passage 3d for removing reject material settling therein, and it is lconnected through a exibie coupling 4I with a drive motor l2 mounted in the back of the base by means of a housing d3.
  • the forward end of the passage 36 is provided with an outlet 44 which-extends forwardly beyond the end of screw 40, and a closure door i5 :or'this outlet is pivoted at the top of the outlet casting and provided with one or morecounterweights t@ for normally holding the door l5 in sealing position on the outer end of the outlet de.
  • the heavy particles which are discharged into the space 33 will also whirl but in a larger spiral as indicated by the stippled arrows 55, thus effectively concentrating the reject material along the outer wall of chamber l2 as settling thereof takes place downwardly inthe chamber towards the conveyor 40, and it will thus be seen that the conditions set up within the chamber l2 all contribute to effective separation of heavymaterial andto prevention of remixing of the separated material with the clean stock. Since all of the stock is forced to whirl as it traverses the inlet conduit and the discharge passage,there is no relatively stagnant central portion such as might exist if the core 25 were not present, and at the same time the construction of the device as shown effectively prevents shortcircuiting of the stock of a high pressure inlet to a low pressure outlet.
  • the arrangement with the outlet conduit located centrally within the annular space 33 is also of assistance in maintaining continued separation of the reject once it has been discharged through passage 3D. Not only does the whirling of the reject in itself tend to prevent remixing, but since the space 33 continuesbelow the level of gap 30 to the lower portion of chamber I2, gravity also acts on the separated material and causes it to settle until it reaches the conveyor 40.
  • Effective separation is aided by the inward flow of clean liquid fromV the passage 5U; which is maintained at a low volumetric rate approximately the volumetric rate atV which the reject material is removed, for example approximately two gallons per minute under the operating conditions described above.
  • This clean' liquid replaces the reject in the flow of clean stock into the outlet conduit, and it provides a back pressure across thev discharge gap which tends to maintain the clean stock on its desired course and is particularly useful in thecase of paper stock since it aids in preventing discharge of fiber with the heavy particles.
  • bits of fiber should initially be discharged through gap 3
  • this back pressure provided by the added flow of clean liquid can be readily predetermined and controlled as desired to regulate the discharge through gap 30.
  • a further aid to effective separating action an the prevention of remixing of reject material with the clean stock is provided by the arrangement of the core 25 with its lower end extending a substantial distance into the outlet conduit and then terminating. The presence of the core in the upper end of the outlet conduit aids in maintaining the -desired whirling motion of all of the stock until after it has entered the discharge conduit, since it maintains the effective flow area of this portion of the outlet conduit substantially equal to that of the discharge end of the inlet conduit.
  • the termination of the core at a position as shown within the outlet conduit increases the effective flow area of the outlet conduit beyond that point and thus produces a corresponding deceleration of the rate of ilow of the clean stock, Iwhich is desirable in effectuating the proper separation of the reject material since the resulting reduced rate of flow of the clean stock materially reduces its carrying capacity for heavy particles.
  • both reject material and fiber are prevented from accumulating at ⁇ any point in such manner as to cause possible change in the flow vrelatively solid slug between the end of the conveyor and the door 45.
  • This sludge is accordingly easy to handle for disposal by shovels Yor in any other convenient Way and without also den change inthe pressure within the unit such as may result from intermittent cleaning or the opening and closing of a continuously operated port type valve, and the pressure within the unit Y therefore remains constant with no peaks and valleys in the resulting efficiency curve.
