Definitions

  • the invention relates to a hydrocyclone according to the preamble of claim 1.
  • Hydrocyclones are used in the purification of suspensions, with particular application in liquid-fiber suspensions, e.g. in the manufacture of pulp and paper products.
  • the Liquid-fiber suspension containing impurities enters the hydrocyclone under pressure through a tangential inlet and is thereby rotated.
  • the rotational movement of Suspension causes a separation of the impurities from the paper or pulp fibers.
  • the Contaminants, such as stones, sand, mineral fillers, metal particles and other heavy Impurities are guided by the centrifugal force to the wall of the separation chamber and on this transported along to the separation cone.
  • the conical area in the axial Flow direction of the suspension tapers, increases the centrifugal force and causes a Concentration of impurities along the inner wall to the outlet for the Heavy dirt.
  • the heavy dirt may leave the hydrocyclone with some acceptable ones Fibers at the narrowest cross section of the separation cone '.
  • the accept of the suspension emerges from the Hydrocyclone in the axial direction along the center line of the separation chamber through an outlet for the Acceptance of material that can be attached either axially or tangentially to the separation chamber.
  • hydrocyclones of the type considered here are with vertical center line operated. Then the separation chamber above the Abscheidekonus', the heavy parts are below from the separation cone and the accepts discharged upward from the separation chamber.
  • DE-A-1642900 discloses a hydrocyclone in which the separation cone into a metallic and a is divided ceramic part.
  • the heavy burden is particularly high when the suspension is made from waste paper.
  • the invention is based on the object to provide a hydrocyclone, which is also at high Wear is economical to operate, especially through low-cost wearing parts. Also worn parts are easy to replace.
  • connection of the items can be done with a - non-ceramic - connection unit, the is tuned to simple pads on the ceramic parts and therefore their Production greatly simplified.
  • the items with a connection unit also held the connection of the hydrocyclone to the heavy fraction rejection system simplified.
  • hydrocyclone is more typical vertical working position shown and described. As you know, it's easy possible and occasionally required for space reasons, hydrocyclones in horizontal or to arrange oblique shape, which does not limit the applicability of the invention.
  • the hydrocyclone of Fig. 1 has an overhead separation chamber 1, in which a Inlet connection 9, the liquid F can be introduced tangentially. In most cases, that is Separating chamber 1 - as drawn here - executed in a cylindrical shape. It settles axially down in a conical separating chamber 8, e.g. made of the same material as the separation chamber. 1 may be, e.g. made of chrome steel or plastic.
  • a separation cone 2 attached, which according to the invention in an upper part 4 and a lower part of the third is divided.
  • these two parts are detachable by a connecting unit 7 connected with each other.
  • the Acceptance A that is largely purified by heavy parts Suspension is at the upper end of the separation chamber 1 axially through an accepts pipe 10th led out.
  • the heavy particles deposited in the hydrocyclone leave the separation cone 2 through the outlet opening 6, possibly still mixed with a portion of the liquid F. in the When installed, the hydrocyclone is connected to a reject discharge system.
  • She is with Advantage transparent and provided at the upper end with a sealing tulip 12, in which e.g. of the Inner diameter corresponds to the outer diameter D of a cylindrical connecting unit 7.
  • FIG. 2 the connection of the lower part 3 and upper part 4 is shown in somewhat greater detail without this figure should meet the claim of a design drawing.
  • Lower part 3 at the parting plane 5 side facing a circumferential radial extension has, which forms a collar 15, whereby a radially projecting collar surface 16 is formed.
  • This collar surface 16 has the shape of a narrow circular ring and is perpendicular to the center line of the Separating cone 'aligned.
  • the upper part 4 has at the parting plane 5 facing side a circumferential groove 17, in which a support ring 19 is inserted.
  • the support ring 19 is advantageous split or slotted on the perimeter so that it can be inserted after the top Screw 14 was pushed from below onto the upper part 4.
  • the support ring 19 forms at its upper side a collar surface 18.
  • the screw 13 is based and 14 axially, so that an axial distortion of the two parts of the separation cone ' can be done against each other.
  • the screw 13 is with a External thread and the screw 14 is provided with an internal thread. So can by twisting be tightened or loosened in the circumferential direction of the screw.
  • the mounting holes 21 for the screwing are introduced axially with advantage.
  • the outer surface of the screw 13 and 14 can be used as a sealing surface (outer diameter D and axial sealing length LV), which will be described in more detail with reference to FIG. 3.
  • Fig. 3 shows the conditions when connecting the hydrocyclone to the reject system something more accurate.
  • a sealing tulip 12 is provided at the upper end clamped, in such a way that it is partially within the sleeve 11 and partially protrudes axially from it.
  • This projecting part here has an inner cylindrical area, whose inner diameter corresponds to the outer diameter D of the connecting unit 7. Thereby can be easily mounted on the hydrocyclone and against the interior of the Seal off the reject system.
  • usually a large number of hydrocyclones in it is important that the connection to the plant is designed as simple as possible and a quick replacement of the hydrocyclone facilitated. This is particularly well ensured with this proposed solution.
  • connection unit be with an axial sealing length LV, which is smaller than the axial extent of the Connecting unit. It is important that the outer contour of the connection unit 7 no axial running grooves or the like has, which prevent the seal.
