Definitions
- the invention relates to a cyclone separator with a crusherrad receiving cylindrical housing part, the one Tangentialeinlaufgephaseuse and a fine dust outlet having, and with a downwardly adjoining separation area, the one down to the cylindrical housing part subsequent conical housing part with product outlet and Secondary air intake includes.
- the curve A describes the cumulative distribution of the ground material, the is fed to the cyclone separator.
- it is is about powder coating for the automotive industry, what in the In connection with the examples will be explained in detail.
- Curve B describes the cumulative distribution using conventional cyclone sight is achieved. It is clear to see that indeed achieved the desired reduction of fine dust content is, but that also reduces the yield above 10 microns becomes.
- the ideal curve C is not with conventional Zyklonsichtem either to achieve approximately, although many attempts have been made to improve the classification.
- DE 196 08 142 A1 discloses a cyclone separator known to improve the classification in the deposition area in the conical, downwardly tapering housing section a having axially extending installation. This one of several sections Built-in installation separates the cyclone-typical, in the peripheral area downwards and upwards in the central area Carrier gas / particle flows from each other. Inside the installation are another mounting body arranged to an upward To achieve nozzle or suction effect.
- a cyclone separator is described in DE 100 30 705 A1, which also has an installation in the separation area, extending from the upper cylindrical housing section into the lower one located conical housing portion extends and himself tapered downwards. Located below this first installation a second installation, the distance below the lower opening the first installation is arranged and the shape of a down has widening cone sheath. The second installation forms with the Exterior housing a defined gap, where a further sighting of the downwardly directed carrier gas / particle flows.
- a cyclone separator is known with a inlet channel for the air-solid mixture arranged above the separator wheel.
- a conical built-in part of the room divided between classifier wheel and housing wall In the transition area from the cylindrical and conical housing part in the area of Secondary air inlet is installed another conical insert.
- 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, where for small particles the drag force is greater than the centrifugal force.
- the product i. H. the coarse fraction of the Collects inside of the cylindrical housing part and from there to slips down into the separation area.
- This coarse-grained good contains but still a residue of fine dust fraction, which by the removed below the conical housing part supplied secondary air should be, by the residual fine dust content upwards in the range the conveyerrades to be entrained.
- Another advantage is that the secondary air quantity significantly can be reduced. This is obviously related to that in the area of the reduction of the flow cross-section for the Secondary air sets a nozzle effect. The efficiency in terms the fluidization of the product is significantly increased. Of the Secondary air content could therefore be reduced by 30 to 50%.
- the flow cross section between reformerrad and the wall of the cylindrical housing part constricted.
- the constriction in the classifying area the lower portion of the classifying area being preferred.
- the annular cross-section with the surface F and with the radial width B of the separator wheel and wall of the cylindrical Housing located annular space between the lower edge of the Tangentialeinlaufgeophuses and the lower edge of the reformerradesti reduced at least one place.

- the reduction or constriction of the flow cross section can done in different ways, it just being on it arrives, that before the separation area, in particular at Transition from classifying and separating area one Cross-section reduction is created.
- the Cross-section reduction can, for example, radially from the outside extend inward or radially from inside to outside.
- the wall of the housing at the location where the Constriction should be present have a radial constriction.
- This radial constriction can in the cylindrical housing part and / or be mounted in the conical housing part.
- At least one aperture is preferred at the location of Used constriction, which is preferably solvable, so lighter according to the product and classification requirements Replacing the aperture is possible. It is also provided by means of Blend a retrofit existing cyclone judges make.
- the bezel can be attached to the housing wall and / or the reformerrad and / or be arranged centrally under the reformerrad.
- the aperture can be an annular disc or to be a slice. It is also possible to use perforated plates or perforated rings use the flow cross section completely or partially cover the product available for the product Flow cross section by size and number of holes or Openings and the dimension of the plate or ring defined becomes.
- the aperture may also be an iris diaphragm, the is infinitely adjustable.
- a diaphragm which is a triangular Cross section has.
- This version has the advantage that through at least one inclined surface the product slightly down can slip and can not be deposited on the aperture. Product losses are thereby avoided and a cleaning in the Area of the aperture can be avoided when changing the product.
- the one facing the tangential inlet housing Angle ⁇ of the triangular aperture between 10 ° and 20 °.
- the tangential inlet housing facing away from the Angle ⁇ of the aperture between 40 ° and 90 °.
- the diaphragm is preferably in the axial direction slidably disposed of the cyclone viewer.
- a preferred embodiment of the diaphragm has at the Inner surface of the wall of the cylindrical housing part adjacent cylindrical ring and a conical ring on. At the surface of the conical ring that slips on the cylindrical housing wall depositing product down into the area of the narrowed Flow cross section and is there from the ascending Secondary air stirred up.
- the cylindrical ring having in the axial direction extending slots, wherein the Slots are preferably open at the bottom and have different lengths.
- the aperture is preferably in the region of the wall of the cylindrical Housing part and there above the lower edge of the treaterrades arranged.
- the aperture can also be down to the room below extend the lower edge of the treaterrades or conical Be arranged housing part, if so a cross-sectional constriction between the aperture and reformerrad is guaranteed.
- the constriction of the flow cross section can also be formed by a component of the classifier wheel.
