Definitions

  • the invention relates to a classifying wheel for a centrifugal air classifier with the Visible air flows through from the outside inwards against its direction of centrifugation, blades arranged in a ring shape and running parallel to the axis of rotation, the between a circular disk carrying the classifying wheel hub and an annular one Cover plate are arranged, with flow channels between the blades by being at a distance from each other and in the direction of the axis of rotation extending surfaces of the blades are formed.
  • classifying devices serve to disperse that which is dispersed in a fluid Separate visible material into a fine and a coarse fraction.
  • the fluid can vary depending on the process engineering requirement a gaseous or vaporous or a be a liquid visual medium.
  • the desired fractions of the End product predefined conditions with regard to the grain size distribution of the respective groups.
  • Centrifugal air classifiers with a deflector wheel are one of the preferred classifiers Production of very fine visual goods at a relatively low level Energy expenditure. For a sharp separation of the visible goods into fine and coarse goods it is necessary that a in all flow channels of the deflector uniform flow with the same mean radial velocity of the Fluids takes place.
  • the separation limit for fine and coarse is namely the radial extent the flow channels within the classifying wheel are not constant. The highest, so The finest separation limit for the fine lies on the outer circumference of the deflector wheel and deteriorates with decreasing radius to the axis of rotation of the Deflector wheel.
  • the coarse material is usually already on the outer circumference of the Rades rejected and gets into the coarse. Only the fines can go further into that Penetrate the inside of the deflector wheel and gets into the fine material with the fluid flow deducted.
  • a first solution to achieve an even flow discloses DE 43 26 604 A1.
  • the flow of the one flowing to the deflector wheel Fluid with the visible material dispersed therein is there outside the Flow channels of the deflector wheel smoothed out and gradually on the The circumferential speed of the deflector wheel accelerates.
  • DE 43 26 604 A1 therefore describes a deflector wheel with annular disks arranged on the outer circumference, which, due to their entrainment effect, enable the deflector wheel to flow evenly without having to rely on a predetermined tangential flow.
  • v ⁇ the speed of the fluid flowing along the outer circumference of the deflector wheel
  • v s the circumferential speed of the rotating deflector wheel
  • the object of the invention is therefore to design a deflector wheel so that a uniform flow inside the flow channels is also realized when the speed of the fluid flowing along the outer circumference of the deflector wheel (v ⁇ ) and the peripheral speed of the rotating deflector wheel (v s ) are not the same, ie if there is an undirected flow on the outer circumference of the deflector wheel.
  • the task is solved by a classifying wheel, which is installed within the Has flow channels that undesirable vortex formation in the Prevent flow channels.
  • the task is characterized by the features of the claims solved.
  • the blades In centrifugal classifier wheels, the blades arranged in a ring shape that the angular velocity of the fluid flow within the through the Scoops limited flow channel at any radial distance from the The axis of rotation of the classifying wheel is constant.
  • the one that comes up Solid vortex has the property that the separation limit on the outer circumference of the Classifier wheel is smallest. The farther the fluid along with those in it dispersed particles penetrates into the wheel interior, i.e. the smaller the radius becomes the greater the separation limit.
  • the invention provides means that the vortex formation within the Flow channels influenced in such a way that no or only a few coarse particles are sucked into the flow channels.
  • the flow channel breakwater on the boundary walls of the Attach blades so that the penetrating into the flow channels Fluid flow broken in the first radial third of the flow channel and there is only vortex formation in this third of the flow channel can occur. Because the vortex is the cause of the suction of coarse particles coarse particles are no longer sucked into the flow channels so far, if the vortex is as close as possible to the outer circumference of the classifier wheel form. If the coarse particles penetrate less into the classifier wheel then it is also less heavily loaded with coarse particles and the Probability that coarse particles penetrate into the interior and thus into the Fine goods can be minimized.
  • the flow is broken in classifier wheels, whose peripheral speed (v s ) is greater than the speed of the fluid flowing along the outer circumference of the deflector wheel (v ⁇ ), on those boundary surfaces of the classifier wheel blades which are located in the direction of rotation.
  • cross sections of which are preferred have a square, rectangular or triangular shape and extend axially over the extend the entire length of the classifier blades. However, depending on Any other cross-sectional shapes can also be used.
  • the desired detachment is decisive for the shape and position of the internals of the inflowing fluid from the boundary surface of the classifier blades and the desired location of the vortex training.
  • the spatial design of the classifier wheel and classifier as well as the The properties of the product to be sifted can differ from one another Location of the vertebra and possibly a different size of the vertebra as advantageous prove. In any case, an improvement will occur if the location of the Vortex occurs on a radius that is larger than the radius for the vertebrae would train if no internals were used.
  • the classifying wheels according to the invention with internals are preferred in classifiers used that work with undirected fluid inflow.
  • When using the Classifying wheels according to the invention can be directed to a pre-acceleration of the Classifying fluids can be dispensed with.
  • the internals can be used with classifying wheels, their Class wheel blades either straight, inclined or angled to the radial direction are arranged progressively.
  • the axial height of the classifier wheel be chosen as large as possible. With classifier wheels with a large axial height, however, to a largely uniform distribution of the radial velocity Flow fluids are respected.
  • the equal distribution of the Radial speeds are determined by the axial classifier wheel height different radial blade depth reached. In the design with Fine material discharge through the ring-shaped cover plate, the bucket depth becomes axial Direction from the circular disc carrying the classifying wheel hub to the ring-shaped one Cover plate smaller.
  • the different blade depth over the axial classifier wheel height causes uniform suction of the flow fluid and thus an even one Radial velocity of the fluid over the axial height.
  • the classifier wheel height can be increased without reducing the quality of view worsen.
  • the design of classifying wheels with different blade depths can also be used in classifying bikes without internals to even out the Radial speed can be used.
  • the classifier wheel from FIG. 1 consists of a classifier wheel hub (1) Circular disc (2), which has radial and annular slits into which the classifier wheel blades (3) can be used. The evenly across the perimeter of the Sifter wheel distributed blades (3) through the circular disc (2) and annular cover disc (4) held. In one embodiment, both Circular disc (2) and annular cover disc (4) as well as the blades (3) Made of steel. The blades (3) are firmly attached to the by soldering or welding Circle (2) - and cover plate (4) connected.
  • Classifier wheel blades (3) are selected, which are made from another and not welding or solderable material, e.g. from ceramic or plastic, see above can the blades (3) preferably by gluing in the slots of the circle (2) - and cover plate (4) are attached. But there are also all others Connection techniques possible. Depending on the material and application, another connection means prove the most sensible. In particular it is The classifier wheel blades are also possible when using steel materials (3) and circle (2) - and cover plate (4) to glue.
  • each classifier blade in the direction of rotation (3) On the front boundary surface of each classifier blade in the direction of rotation (3) the internals (5) are attached.
  • the internals (5) have, for example, one square cross-section and extend axially over the entire Bucket height. You can e.g. by welding, soldering or gluing with the Boundary surfaces of the classifier wheel blades (3) are connected.
  • the internals are preferably on a common radial Circular path that is roughly in an area within the outer third of the radial Total width of the classifier wheel blades (3) is.
  • the classifying wheel shown in FIG. 2 differs from that in FIG. 1 classifier wheel shown by the arrangement of classifier wheel blades (3).
  • the Classifier wheel blades (3) do not run exactly in the radial direction, but are in rotated at an angle to the radial direction against the direction of rotation arranged. If the classifier wheel blades (3) are close to the Extend the axis of rotation, the classifier wheel blades (3) remain in the inner area radially aligned, whereas the classifier wheel blades (3) in the outer area are rotated at an angle to the radial direction.
  • the Classifier wheel blades (3) thereby form a flow channel with a kinked course.
  • Classifying wheel blades (3) can also be used, which do not extend far extend into the inside of the classifier wheel, but only over an outer one extend radial area of the wheel. Such a design is shown in FIG. 3 shown.
  • the internals can have different cross-sections depending on the application exhibit.
  • the internals on the classifier wheel blades (3) according to FIG. 3 do not have a square cross section, but essentially consist only of a step-shaped heel (6), which is already in an advantageous embodiment the classifier wheel blade (3) is integrated and not additionally with the Classifier wheel blades (3) must be connected.
  • the classifying wheel blades are made of formed two sections.
  • the sections located radially on the inside run rectilinear in the radial direction.
  • the radially outer sections are in accordance Fig. 4 arranged obliquely. At the kink between the oblique and straight Blade sections protrude beyond the outer end of the inner section Kink point and thereby forms the flow edge according to the invention.
