Definitions

  • the invention is directed to a classifying wheel for a centrifugal force air classifier according to the preamble of claim 1 and a method for separating classifying material dispersed in a classifying fluid into a fine and a coarse fraction according to the preamble of claim 10.
  • Air classifiers are used to separate material dispersed in a fluid into a fine and a coarse fraction.
  • the separating effect of a classifying wheel is based on the fact that the drag force of the fluid and the centrifugal force in the flow channels between the classifying wheel blades of a classifying wheel, the so-called deflector wheel, act on the individual particles of the solid in opposite directions.
  • the drag force predominates, so that they are carried along by the fluid and discharged as fines.
  • centrifugal force predominates, so that they are thrown out of the deflector wheel against the fluid flow.
  • the particle size for which centrifugal force and drag force are in balance, i.e. which is equally likely to end up in the fine or coarse material, is called the separation particle size or separation limit.
  • Centrifugal force wind sifters with deflector wheels are one of the preferred sifters for producing very fine sifted goods with relatively little energy expenditure. For a clear separation of the visible material into fine material and coarse material, it is necessary that there is a uniform flow with the same average radial velocity of the fluid in all flow channels of the deflector wheel.
  • This sucking out of the fine material from inside the sifting wheel creates unstable flow conditions during sifting, which prevent higher fineness from being achieved.
  • This outflow occurs depending on the selected operating conditions during sifting and takes place at least in a flow channel between two sifting wheel blades.
  • the invention is therefore based on the object of providing a sifting wheel and a sifting method which prevents unstable flow conditions due to the formation of eddies in flow channels of sifting wheels.
  • the classifying wheel according to the invention for a centrifugal force air classifier is arranged in a rotationally driven manner and is flowed through from the outside to the inside in the opposite direction to its centrifugal direction. It has sifting wheel blades arranged in a ring between two holding disks. The classifying wheel blades and the retaining disks limit the flow channels. Internals that influence the course of flow are arranged in these flow channels.
  • the separating wheel according to the invention has additional internals in its flow channels, which are delimited by the separating wheel blades, near the outlet side of the flow channels, i.e. towards the axis of rotation of the separating wheel. These internals result in the same or at least similar amount of fluid flowing through the individual flow channels.
  • the internals prevent fine material from flowing from the center of the sifting wheel back into the sifting space outside the sifting wheel, thereby stabilizing the flow through the sifting wheel.
  • the internals are located within the inner two-thirds (2/3) of the sifting wheel radius in the flow channels.
  • Flow simulations of deflector wheels with internals in the outer third of the flow channels show that in addition to the screening vortex within the radially outer third of the screening wheel radius, a second vortex forms in the flow channels of the screening wheel. This second vortex sucks material - fines - out of the center of the separating wheel. In cooperation with the sifting vortex, fine material can be discharged into the sifting space around the sifting wheel. This is undesirable.
  • the internals in the radially inner two thirds of the flow channels prevent this by creating the vortex is limited radially inwards by the internals. As a result, the vortex is not only limited on the inside, but also on the outside, namely by the internals that limit the outer visual vortex radially inwards.
  • the internals are preferably located on a common radial circular path, which is approximately in an area that lies within the inner two-thirds of the viewing wheel radius.
  • Internals serve as flow breakers in the radially inner region of the separating wheel blades, the cross sections of which preferably have a polygonal (e.g. square, rectangular, square, triangular) or round shape or a combination thereof and preferably extend axially over the entire axial height of the separating wheel blades or the flow channels .
  • a polygonal e.g. square, rectangular, square, triangular
  • round shape e.g. square, rectangular, square, triangular
  • any other cross-sectional shapes can also be used.
  • these internals do not extend over the entire axial height of the separator blades. In a further embodiment, the internals are not located on a common circular path around the axis of rotation of the classifying wheel.
  • the radial distance of these internals from the classifying wheel axis is not constant along the height of the classifying wheel axis.
  • the internals are designed in such a way that they continuously narrow the flow channel from a radially further outward position to a radially further inward position. This should mean that the narrowing occurs without one or more angular gradations.
  • These internals can be located either on both sides of the classifying wheel blades or only on the front or back of the classifying wheel blades as seen in the direction of classifying wheel rotation.
  • a preferred variant of the internals is approximately flush or flush with the separator blades on the inside.
  • the size and shape of the internals can vary depending on the application. A combination of two or more differently shaped internals is also possible.
  • the separator blades and the internals can be made from one part or from several parts.
  • the classifying wheel in the flow channels additionally has internals within the radially outer third, based on the classifying wheel radius.
  • the internals are designed as sheets with holes or openings and protrude over the entire height and width of the flow channels. They are arranged in the flow channels.
  • the contour of the sheets preferably follows the circular path around the axis of rotation Classification wheel on which they are arranged.
  • the sheets are at a constant distance from the sifting wheel axis. The distance is less than two thirds of the viewing wheel radius. This type of installation also limits the vortex inwards.
  • the holding disks, between which the classifying wheel blades are arranged, can be designed as a hub disk or cover disk.
  • the cover plate is provided with a fines outlet. It is preferably designed in a ring shape.
  • the classifying wheel according to the invention can be designed with either a single or double flow.
  • a double-flow sifting wheel can be composed of two single-flow sifting wheels.
  • the sight wheels are assembled on their cover plates so that they have a common axis of rotation.
  • the double-flow classifying wheel now has two hub disks and is mounted on both sides in the housing of the centrifugal force air classifier.
  • the two hub disks have openings that represent the fine material outlets.
  • the cover disks in the middle of the sifting wheel are omitted, so that it has a continuous interior area.
  • the internals a in the radially outermost area of the classifying wheel blades mean that the momentum of the inflowing fluid is converted into a speed increase in the classifying vortex more efficiently than in the case of the patent EP 0 983 802 A2 revealed sight wheel.
  • variants that have discontinuous courses of the specially shaped separator blades due to kinks and edges are not as efficient as variants with continuous contours due to losses in the exchange of momentum. Since the variants with bent viewing blade ends do not convert the momentum of the inflowing fluid as efficiently, the speed increases are lower compared to continuous contours.
  • the flow in the sifting wheel could be stabilized and the fineness range of sifters could be improved towards smaller finenesses.
  • the Figure 1 shows a classifying wheel (10) for a centrifugal force air classifier. It comprises a hub disk (2) carrying the classifying wheel hub (1) and an annular cover disk (4).
  • the ring-shaped separating wheel blades (3) are arranged between these disks. They are evenly distributed over the circumference of the sifting wheel (10).
  • the classifying wheel blades (3) are essentially aligned radially and delimit the flow channels.
  • the separating wheel (10) is flowed through from the outside to the inside by the separating fluid loaded with particles, for example separating air.
  • the sifting wheel (10) according to the invention has flow channels which have internals (5) in the outer third, based on the sifting wheel radius, and in addition to these internals, further internals (7) in the inner two thirds of the flow channels, based on the sifting wheel radius. These narrow the flow channel (6) on the outlet side and thereby stabilize the flow in the classifying wheel (10).
  • the separating wheel blades (3) do not run exactly in the radial direction in the radially outer third, the separating wheel radius, but are arranged inclined at an angle to the radial direction opposite to the direction of rotation. In the inner two thirds they are aligned radially.
  • the inner vortex is limited on both sides by the internals (5, 7).
  • the fluid with particles no longer flows out of the center of the sifting wheel to the outside into the sifting space around the sifting wheel, thereby stabilizing the flow through the sifting wheel.
  • the course of the undisturbed flow of fine material from the outside to the inside is indicated by the thick arrow in the Figures 2 and 3 shown.
  • the internals (7) are preferably located on a common radial circular path, which is in an area that lies within the inner two thirds of the viewing wheel radius.
  • Figure 3 shows another embodiment of the internals (7). They are designed in such a way that they continuously narrow the flow channel (6) from a position located further radially outward to a position located further radially inward. This should mean that the narrowing occurs without one or more angular gradations.
  • These internals (7) are only located on one side of the flow channel (6). The internals (7) are almost flush with the inside of the classifying wheel blades (3). You can also finish flush.
  • the internal internals (7) are designed in such a way that the internals (7) together with the classifying wheel blades (3) converge radially inwards in a point, this prevents material deposits on the inner classifying wheel blade edges.
