Definitions

  • the invention relates to a cyclone separator according to the preamble of claim 1.
  • cyclone gauges are described, for example, in US Pat. Cyclone Classifier for Inline and Offline Classification "by J. Galk, W. Peukert, in” powder, handling & processing ", Volume 8, Number 1, January / March 1996 and in " Fine Grinding System with Impact Classifier Mill and Cyclone Classifier "by Marc Giersemehl and Günter Plihal, in” powder, handling & processing ", Volume 11, Number 3, July / September 1999, pages 269-274 described.
  • the classifying region where the classifying wheel is arranged
  • the separating region which designates the space below the classifying wheel and generally comprises the interior enclosed by the conical housing part. The transition from classification to separation depends on the design of the cyclone separator.
  • Cyclone gauges are usually connected to shredders, whose regrind is introduced through the tangential inlet into the cyclone body.
  • Zyklonsichtem can a classification of powders with grain sizes in the range of a few millimeters to a few microns are performed.
  • the particles are separated from the ground material, which are either too big or too small.
  • the separation of the so-called fine dust must not be at the expense of the yield of the remaining Komfr syndromeen.
  • the curve A describes the cumulative distribution of the material to be ground, which is fed to the cyclone separator.
  • it is coating powder for the automotive industry, which will be explained in detail in connection with the examples.
  • Curve B describes the cumulative distribution achieved with conventional cyclone sighting. It can clearly be seen that, although the desired reduction of the fine dust content is achieved, the yield above 10 ⁇ m is likewise reduced.
  • a Zyklonsichter known which has an axially extending installation to improve the classification in the deposition area in the conical, downwardly tapered housing portion.
  • This built-up of several sections installation separates the typical cyclonic, in the peripheral region downwards and in the central region upwardly directed carrier gas / particle flows from each other.
  • Inside the installation further mounting body are arranged to achieve an upward nozzle or suction effect.
  • a cyclone separator is in the DE 100 30 705 A1 to find, which also has an installation in the separation area, which extends from the upper cylindrical housing portion in the underlying conical housing portion and tapers itself conically downwards.
  • a second installation which is located at a distance below the lower opening of the first installation and has the shape of a downwardly widening conical surface. The second installation forms a defined gap with the outer housing, where a further screening of the downwardly directed carrier gas / particle flows is to take place.
  • a cyclone separator which has a cone-shaped installation part beneath the separator wheel within the separation region in the conical housing part.
  • the grinding material supplied to the cyclone separator is subject to the centrifugal force on the one hand and the drag force on the other hand, with the drag force being greater than the centrifugal force for small particles.
  • the product, d. H. the coarse-grained fraction collects on the inside of the cylindrical housing part and from there slides down into the separation area.
  • this coarse-grained good still contains a residual amount of fine dust, which should be removed by the supplied from below the conical housing part secondary air by the residual fine dust is to be entrained upwards in the range of conveyerrades.
  • Another advantage is that the secondary air quantity can be significantly reduced. This is obviously related to the fact that in the area of reduction of the flow cross-section for the secondary air, a nozzle effect is established. The efficiency with regard to the fluidization of the product is significantly increased. The secondary air fraction could therefore be reduced by 30 to 50%.
  • a further advantage is that expensive installations in the separation area, in particular in the lower area of the separation space, can be dispensed with. Even internals that act as a flow divider are dispensable.
  • the flow cross-section between reformerrad and the wall of the cylindrical housing part is constricted.
  • the constriction is in the classifying region, with the lower portion of the classifying region being preferred.
  • the flow cross-section is constricted at the level of the lower edge or in the region above the lower edge of the classifier wheel.
  • the lowering of the installation position of the classifier wheel with respect to the tangential inlet housing has the advantage that the fluid swirled up by the secondary air passes directly to the classifier wheel and this flow path is not disturbed by the supply of new millbase through the tangential inlet.
  • the annular cross-section with the surface F and with the radial width B of the annular space between reformerrad and wall of the cylindrical housing part between the lower edge of the Tangentialeinviergepatuses and the lower edge of the reformerradesti is reduced at least one point.
  • the extent to which the cross section of the annular space is to be reduced depends essentially on the particle size of the ground material. The greater the rate of descent of the product, the greater should be the constriction of the flow cross-section should be selected. The constriction should be so great that the rate of ascent of the secondary air in the area of the constriction is significantly greater than the rate of inflow at the secondary air inlet.
