Definitions
- the invention relates to a wind sifter principle working classifier with the features of the generic term of claim 1 (see CH-A-285112).
- the bladed rotors serve in classifiers of this type the realization of a forced vertebral sink flow.
- the shape of the rotors can be cylindrical or conical, the blades or rotor blades being different Can have shapes and angles of attack.
- the one to be classified Solid and the fluid (gas or liquid) become added together (as an aerosol or suspension) or separately. Inside the rotor the flow is from the blades and the adjacent tube disks a movement component embossed in the circumferential direction. As a result of the effect of each other opposing forces - centrifugal force, drag force of the fluid - the desired classification takes place.
- classifiers of this type regardless of whether the fluid used is a gas or a liquid is optimal Flow conditions a basic requirement, especially for the selectivity of the classification.
- the rotor disks extend to the outer circumference of the blading.
- the channel is on three sides of the Housing and on one side from the outer circumference of the rotor enclosed.
- the fixed part of the inner walls of the outer channel i.e. the area that is related to product fluid flow has a braking effect relatively large. This leads to friction losses and to developing secondary currents, i.e. flow turbulence, that affect the quality of the classification.
- the present invention is based on the object to create a classifier of the type mentioned at the beginning, in which the described, impairing the classification Turbulence is minimized.
- the housing of the classifier is 1, the rotor with 2, its axis of rotation with 3, its blading with 4, the rotor blades enclosing the blading 4 designated 5 and 6 and the outer channel 7.
- the diameter of the rotor disks are chosen so that their outer edges 8 and 9 extend into the channel 7 and form lateral boundaries of the channel 7.
- the embodiment of Figures 3 and 4 differs differs from the exemplary embodiment according to FIGS. 1 and 2 in terms of solids delivery.
- the housing 1 is in the area of the upper rotor disc 5 with an annular Recess 15 equipped together with the the upper rotor disk 5 extends up to approximately the outer edge 8 extending annular chamber 16 forms.
- the supply of the solid or an aerosol (or a suspension) takes place via a radially inner inlet 17 (Arrow 18). On the way to the outside, the supplied good already accelerated in the circumferential direction. It leaves the Chamber 16 over a variety of in the rotor disc 5th or the outer edge 8 formed openings 19, the in the illustrated embodiment in the separation zone (Channel 7) flow out.
- the openings 19 are formed such that to the chamber 15 first an obliquely outwards and line section 20 extending in the direction of channel 7. This essentially turns into itself extending axially parallel to one in radial Direction of elongated mouth 21 expanding line section 22.
- Figure 4 shows a plan view of part of the underside the rotor disk 5 or its edge 8. It can be seen that the line sections 22 too elongated, about expand oval mouths 21. In the breakthroughs 19 receives the supplied good the radius of the Location of the mouths 21 corresponding peripheral speed.

Description
- Eine starke Abbremsung der Strömung in Umfangsrichtung, die zu einem schnelleren Abfall der Umfangsgeschwindigkeit führt und sich nachteilig auf die Klassierung auswirkt, wird vermieden,
- eine sich ausbildende Sekundärströmung an der oberen und unteren still stehenden Begrenzungswand wird verhindert,
- Reibungsverluste aufgrund des in Umfangsrichtung großen Geschwindigkeitsgradienten zwischen stillstehender Gehäusewand und rotierendem Fluid/Feststoff werden verringert oder gar vermieden, so daß der Druckverlust minimiert wird,
- durch eine geschwindigkeitsgleiche Zuführung von Fluid und/oder Feststoff wird sowohl ein weiteres Abbremsen der Strömung als auch eine Minimierung der Strömungsturbulenz erreicht, die durch den Impulsaustausch zwischen Fluid und Feststoff verursacht wird.
- Figuren 1 und 2 Teilschnitte durch einen Rotor nach der Erfindung mit tangentialer Feststoff/Fluidzuführung,
- Figur 3 einen Teilschnitt durch einen Rotor mit achsparalleler Feststoff/Fluidzufuhr und
- Figur 4 eine Draufsicht auf die beim Ausführungsbeispiel nach Figur 3 der Feststoff/Fluidzufuhr dienenden Öffnungen.
