Definitions

  • the invention relates to the separation of a fine grain in a liquid dispersed solid in a fine and a coarse. It concerns one procedure and one Device for performing this separation in the grain size range below about 50 microns, preferably below about 10 microns.
  • hydrocyclones are preferably used, in which the Influence of centrifugal force, wall friction and drag force of a liquid on the Solid particles, this separation is achieved.
  • EP 0 355 285 A2 discloses a device in which a fine-grained solid in one dripping liquid is dispersed and the dispersion in a sink flow with superimposed rotational flow is forced.
  • the rotating working part used to separate the fine material consists of one Stack of cutting discs with free ones between the cutting discs Gaps.
  • the rotating cutting disc stack is therefore loaded with coarse particle flows, whereby only a lower throughput of fine material flow through the cutting disc stack can be achieved.
  • the invention is therefore based on the object of a method and an apparatus for Separation of a fine-grained solid into a fine material and a coarse material to be specified in economically a sharp separation, especially in the grain size range enable below about 10 microns.
  • the fine-grained Solid dispersed in a drippable liquid and the dispersion in a defined Sink flow with superimposed, regardless of the sink flow generated Forced rotational flow.
  • the ratio of doing so independently adjustable speeds of sink and rotational flow determines the Separation grain size or separation limit between fine and coarse goods, i.e. the particle size, for the centrifugal force generated by the rotation and that by the sink flow generated drag force of the liquid are in equilibrium, that is, with the same Probability of getting into the fine or coarse material.
  • the method according to the invention can thereby be particularly simple realize that sink and rotational flow are rotating in one driven deflector wheel with flow from outside to inside parallel to its axis of rotation and flow channels forming blades are generated, the solid dispersion of the Deflector wheel is abandoned on the outer circumference.
  • the one suitable for carrying out the method according to the invention Device consists essentially of a pressure-resistant housing with Connections for introducing the feed dispersion and that Discharge of fine and coarse material dispersion, at least one in Housing rotatably mounted and driven deflector wheel and one Feed pump for feeding the feed dispersion.
  • Beneficial Embodiments of this device are in claims 5 to 12 shown.
  • the deflector wheel is arranged in a closed housing, into which the solid to be classified and dispersed in a liquid - the feed dispersion - is conveyed with a feed pump via an inlet connection.
  • the dispersion flows through the rotating deflector wheel from the outside in, whereby the solid is separated into fine and coarse material. Particles in which the drag force exerted by the flowing liquid is smaller than the centrifugal force induced by the rotation of the deflector wheel cannot get inside the wheel and are rejected. Particles where the drag force is greater than the centrifugal force enter the inside of the wheel with the liquid.
  • This part of the dispersion thus contains the fine material fraction and leaves the housing of the separating device through a discharge connection which connects to the interior of the deflector wheel.
  • the rejected particles leave the housing with the remaining part of the liquid as coarse material dispersion through a second discharge connection.
  • the fine material dispersion must Flow through the wheel against the centrifugal force a relatively high Overcome pressure.
  • This pressure depending on the operating state in the The order of 3 to 20 bar is achieved by the feed pump upset.
  • the housing of the Separating device and also the bearing of the drive shaft for the Deflector wheel be designed pressure-resistant; for the latter is in the in most cases the use of a mechanical seal is required.
  • the operating sizes that determine the size of the separation grain are Peripheral speed of the deflector wheel and the radial Flow velocity in its formed by blades Flow channels.
  • the peripheral speed can be given Outside diameter of the deflector wheel solely based on its speed be set; the radial flow velocity results from the free flow cross section of the deflector wheel and the Volume flow of the fine material dispersion.
  • This together with the Volume flow of the coarse material dispersion are determined by the inflow quantity of the Feed dispersion determined by the conveying capacity of the Feed pump is set. Because the fines dispersion is usually
  • the volume flow is set to flow freely indirectly via the feed quantity and the division ratio of the Volume flows of fine and coarse material dispersion. The change of this Division ratio takes place in that the volume flow of the Coarse material dispersion is changed, e.g. by changing the Discharge cross-section or by metered pumping the Coarse material dispersion.
  • the axis of rotation of the deflector wheel lies in the axis a rotationally symmetrical, e.g. cylindrical housing in which the Liquid and the solid dispersed therein without special Measures rotated evenly with the deflector wheel.
  • a rotationally symmetrical e.g. cylindrical housing in which the Liquid and the solid dispersed therein without special Measures rotated evenly with the deflector wheel.
  • the radial distance between the Inner wall of the container and the circumference of the deflector wheel are small maintained, a uniform flow against the deflector wheel is achieved over its entire length. Short circuit currents and backflow effects can be avoided effectively.
  • Optimal Flow conditions are achieved when the radial distance between inner wall and wheel circumference less than 10% of the diameter of the Deflector wheel is.
  • the termination for the feed dispersion can be above, below or be attached to the housing in the area of the deflector wheel, wherein a tangential junction with inflow in the direction of rotation of the Deflection wheel the pre-acceleration of liquid and solid favored.
  • An additional pre-classification effect can be achieved if the connection for the feed dispersion with inflow in axial direction at the lower end of the housing and central to it is arranged. Coarse particles are thereby brought close to the Housing wall worn so that they no longer burden the deflector wheel, but are carried out directly.
  • a longer flow path e.g. by changing from the connection cross-section to the housing cross-section Expanding, conical housing part can still have the pre-classification effect improve.
  • the deflector wheel can be a cylindrical paddle wheel in a known manner be designed with a free interior. Which is in this interior however, forming potential vortex flow produces a high one Pressure loss, so that the use of such a deflector wheel only low speeds makes sense, i.e. for relatively rough separations with small throughputs.
  • the flow can be reduced due to its rotationally symmetrical design and coaxial with the deflector wheel arranged moldings improve, the radially aligned blades of the deflector wheel from its circumference to the Extend molded body.
  • the molded body can e.g. as cylinder, cone or truncated cone.
  • Fig. 1 shows a schematic representation of an invention trained device with a cylindrical housing 1 to which the Storage 8 for receiving the deflector wheel 3 is flanged directly.
  • the vertical-axis de-icing wheel 3 becomes the pulley 12 and Hollow shaft 9 driven their bearings with a shaft seal 6 against the interior of the housing 1 are sealed.
  • What to separate, in a liquid dispersed feed is through port 2 in the Pumped housing 1, from where it enters the deflector 3. That through the separating action of the deflector wheel 3 separated fine material is combined with a part of the liquid as a fine dispersion through the Hollow shaft 9 discharged into the fixed fine material collector 10 and flows through connection 4 for further use.
  • Fig. 2 shows a variant with several, horizontal-axis Deflector wheels 3, which are arranged in a common housing 1.
  • Each deflector wheel 3 has its own (not shown here) Motor driven by pulley 12. This makes it possible to Set the speed of each deflector wheel 3 individually, so that from one feed dispersion also several at the same time differently composed fines dispersions are subtracted can.
  • This variant is preferably used for high Throughputs at lower and the same for all deflector wheels To reach the separation limit.
  • Fig. 3 is in place of the straight bottom of housing 1 (Fig. 1) funnel-shaped, tapered component 14 fastened, at its lowest point, port 2 for the inlet of the Feed dispersion flows.
  • the connections 2 and 5 reversed their position.
  • This training serves one To achieve pre-classification of the feed material, such that the rotating Deflector wheel 3 causes rotation of the introduced dispersion by the coarse particles before entering the deflector wheel 3 to the Interior bounding walls carried by component 14 and housing 1 and be braked there so that they no longer enter the deflector wheel 3 can occur, but carried out directly through the port 5 become.
  • the quantity setting for the coarse material dispersion is made here by the slide 7 inserted directly into the connection 5.
  • the bumpers 3 in Figures 1 to 3 consist essentially of two limiting disks connected with each other at an axial distance 15, 16, between which and parallel to the axis of rotation Blades 17 forming flow channels over the circumference of the disks are evenly distributed, being perpendicular or at an angle can be aligned to the scope.
  • Through a central hole in the one limiting disk 15 is the fine material dispersion in the Hollow shaft 9 discharged.
  • the through the outer edges of the blades 17th certain circumferential surface is a cylindrical surface. But it can also as in Fig. 4 as the largest diameter conical surface on the Boundary disk 15 to be formed with the central bore a more even flow through the deflector wheel 3, especially in to reach free interior.
  • the deflector wheels 3 of FIGS. 6 and 7 in turn have a cylindrical circumferential surface, the blades 17, which are oriented radially here, however, extending up to the axis of rotation of the deflector wheel 3. In this version, there is no potential vortex, but one Solid-state vortex flow in deflector wheel 3.
  • flat annular disks 19 are also attached at the same mutual spacing, which extend radially outward from the outer circumference of the deflector wheel 3 and serve to pre-accelerate the feed material dispersion flowing in from the outside of the deflector wheel 3.
  • FIGS. 8 and 9 show a deflector wheel 3 in longitudinal and cross-section with coaxial shaped body in the form of a cylinder, which is part of the Hollow shaft 9 is formed.
  • the molded body has a gap opening 20th in the length of the axial extension of the blades 17 through which the Fine material dispersion can enter the hollow shaft 9, from where it over the fines collector 10 and connection 4 ( Figures 1 to 3) from the Separating device is removed.
