Definitions

  • This invention relates to hydrocyclones. More particularly, it relates to a structural unit comprising a plurality of hydrocyclones, which unit is usually termed a multiple hydrocyclone.
  • Hydrocyclones are known to be useful in classifying, thickening, and otherwise separating solids suspended in liquids.
  • a hydrocyclone is an enclosed vortex space bounded along the length thereof by a continuous surface of revolution with a smooth inner wall, having feed inlet means disposed tangentially either clockwise or counter-clockwise to the surface of revolution at one end thereof as well as having at the same end a base located, axially disposed, discharge outlet or overflow aperture, and having axially disposed at the opposite end of the space a second discharge opening or underflow aperture.
  • the vortex space is enclosed by a cylindrical chamber subtended by and opening into without interruption a conical chamber.
  • the underflow aperture is usually located at the apex of the conical space and is sometimes referred to as the apex discharge outlet, while the feed inlet means are usually disposed tangentially to the widest part of the space.
  • a tubular member is often referred to as a vortex finder.
  • a liquid containing solids is introduced into the cylindrical chamber through the tangential feed inlet means under enormous pressures so that the feed slurry whirls about the vortex space producing centrifugal forces so great that the force of gravity is in eifect eliminated. Accordingly, under these conditions, a hydrocyclone may be successfully operated in any position. A fraction of the feed upon introduction into the vortex space is discharged through the base aperture as overflow. As a result of the centrifugal forces and drag forces so developed, there occurs a segregation of the solids within the liquid feed based upon the differences in gravity settling rates in still water.
  • one object in general of this invention is to devise a multiple hydrocyclone Without these disadvantages.
  • an object of this invention is to devise a multiple hydrocyclone with an increased capacity per unit of space occupied whereby the amount of unused space is minimized and the number of individual hydrocyclones per unit of space is maximized.
  • Another object of this invention is to devise a multiple hydrocyclone of such structural simplicity that not only are construction costs minimized but the parts can be made more uniformly and without the requirement of close tolerances.
  • this invention comprises a block of material with vortex spaces between opposite ends of the block aligned with respect to their longitudinal axes and separated by the material from each other, each vortex space comprising a cylindrical space subtended by a conical space with a coaxial discharge aperture at its apex, and a specially adapted removable cover member covering the cylindrical portion of each vortex space.
  • Each cover member comprises a plate the end adjacent the block being slightly larger than the vortex space, a central discharge outlet disposed through the plate and in axial alignment with the vortex space, a channel-shaped groove extending from and through the side of the plate along the surface of the end adjacent to the block, and adapted to be substantially in tangential alignment with the vortex space when the discharge aperture in the plate is in axial alignment with the vortex space, which groove cooperates with the end surface of the block to form a feed inlet to the hydrocyclones formed by the vortex space and the cover member; Positioning means for maintaining the position of the cover member may also be included.
  • the block and cover members in place are disposed between two metal clamping plates having apertures corresponding in position to the vortex space discharge outlets, means for introducing feed slurry to the spaces formed between the clamping plate pressing down on the cover members and the block, means for collecting discharge from the cover member discharge outlets, means for collecting discharge from the apex discharge outlets, and means for clamping the plates together.
  • the vortex spaces may be entirely recessed in the block.
  • the depth of the delivery section of every feed channel in each. cover member should preferably be gradually diminished in order that when the cover member is in position the feed channel will debouch into the vortex space at a small angle in relation to a plane perpendicular to the axis of the hydrocyclone.
  • a portion of the vortex space may be recessed in the plate portion of the cover member. In such case the feed channel can be of constant depth.
  • each cover member discharge aperture may be curved and the sidewalls thereof may converge over the vortex space. Furthermore for best operation it is preferred to provide each cover member discharge aperture with a vortex finder.
  • cover members be radially symmetrical about the sides thereof with the axis of radial symmetry coinciding with that of the cover member aperture.
  • This shape is preferred in order that in operation the common feed chamber formed between the block and the clamping plate will contain no dead areas where liquid suspension containing organic matter may collect and decay.
  • the block be also radially symmetrical about the periphery of the infeed end and the underfiow end.
  • the feed inlet face away from the overall direction of feed slurry flow over the surface of the block. Since it is a feature of this invention that more than one feed inlet to each vortex space may be easily used, the above preference is satisfied if one feed inlet is faced away from the overall direction of feed slurry flow across the end of the block by proper positioning of the cover member, and that the remainder be spaced equidistantly from the first feed inlet about the infeed end of the cover member.
  • Such means may comprise a side wall extension of the cover member, except only for that portion about the feed channel entrance, and interrupted grooves about the vortex space adapted for the corre sponding extension of the sidewalls, the grooves being so located that when the cover member is centrally positioned over the vortex space the overflow aperture is centered on the axis of the vortex space and the feed inlet is facing in the desired direction.
  • This invention presents an advantage in that all feed channels may be formed by means of one mold or matrix.
  • the block and cover members be molded or cast out of a resilient material in order that operating hydraulic pressures and clamping forces may be most efl'iciently utilized to prevent leakages in and out of the structural unit.
  • Feed slurry may be introduced into the space around the cover members by a feed conduit which passes in axial alignment through the common overflow discharge chamber, and into the space through the clamping plate pressing against the cover member.
  • An alternative feed slurry means which is desirable under certain conditions, comprises a feed conduit passing through the common underfiow discharge chamber, through the clamping plate separating the chamber from the block, and into an axially aligned hole in the block communicating between the two ends of the block.
  • the feed conduit end of the hole is preferably lined about the circumference with a sealing lip of resilient material projecting outwardly and at a small angle from the side of the hole such that when the feed conduit is inserted through the hole the sealing lip will be pressed about the feed conduit by hydraulic pressure under operating conditions.

  • Each of the vortex spaces comprises a cylindrical section 23 sub tended by a conical section 24.
  • the cylindrical section opens directly onto one end of the block 21, which end shall be referred to hereinafter as the infeed end, while at the apex of the conical section 24 there is an axially aligned passageway 25 referred to as the apex discharge outlet or underflow discharge outlet opening onto the opposite end of the block 21, which end shall be referred to hereinafter as the underflow end.
  • each vortex space is capped by a cover member 26 likewise constructed from a resilient rubber material and especially adapted to provide, when in position, a feed slurry conduit 27 extending from the side of the cover member 26 tangentially to the vortex space 22.

  • a feed slurry conduit 27 is formed extending from outside the cover member into the vortex space, one wall thereof consisting of the flat surface 29 of the infeed end of the block 21, and the remaining walls thereof consisting of those of the channel 28.
  • FIG 4 wherein the sectional view of the cover member 26 corresponds to that of section 4-4 in Figure 5.
  • Axially disposed through the cover member 26 is a vortex space discharge passageway 30 through which vortex finder 31 is tightly inserted and axially aligned.
  • the vortex finder is also constructed out of a resilient rubber material. To minimize leakages and to maintain the vortex finder in position, it is desirable to construct the vortex finder 31 with a shoulder 32 at the inlet end thereof.
  • each of the cover members is in proper position, and each of the vortex spaces cooperate together to form individual hydrocyclones.

  • the purpose of interrupting the cylindrical wall 34 is to prevent the cover member 26 from turning about its axis under operative conditions. While this interruption may be located at any place around the cylindrical wall 34, it is preferred that it be disposed about the entrance to the groove 28 as in Figure 3, for ease in molding the cover member 26.
  • FIG. 7 Another cover member embodiment of this invention as illustrated in Figures 7, 8, 9, and 10, is advantageous whenit is desired to reduce the distance between the underflow end and the infeed end of the multiple hydrocyclone block without reducing the dimensions of the vortex space or, conversely, where it is desired to increase the length of the vortex spaces without increasing the dimensions of the block.
