Definitions
- the invention relates to a classifier working according to the wind sifter principle with the features of the preamble of claim 1.
- the bladed rotors serve to implement a forced vortex sink flow.
- the shape of the rotors can be cylindrical or conical, and the blades or rotor blades can have different shapes and angles of attack.
- the solid to be classified and the fluid (gas or liquid) are added together (as an aerosol or suspension) or separately.
- a flow component in the circumferential direction is impressed on the flow from the blade and the adjacent tube disks.
- classifiers of this type regardless of whether the fluid used is a gas or a liquid - optimal flow conditions are a basic requirement, especially for the discriminatory power of the classification.
- the rotor disks extend to the outer circumference of the blading.
- the channel serving to feed the solid and the fluid is enclosed on three sides by the housing and on one side by the outer circumference of the rotor.
- the fixed portion of the inner walls of the outer channel that is to say the area which has a braking effect on product fluid flow, is therefore relatively large. This leads to friction losses and to secondary currents which form, that is to say flow turbulences which impair the quality of the classification.
- the present invention is based on the object of providing a classifier of the type mentioned at the outset, in which the turbulences which have been classified and which impair the classification are minimized.
- FIGS. 1 to 4. Show it
- FIG. 3 is a partial section through a rotor with axis-parallel solid / fluid supply and
- Figure 4 is a plan view of the openings used in the embodiment of Figure 3 for the solid / fluid supply
- the housing of the classifier is identified by 1, the rotor by 2, its axis of rotation by 3, its blading by 4, the rotor disks including blading 4 by 5 and 6 and the outer channel by 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 supply of solid and fluid takes place via a tangentially directed inlet (inlet nozzle 11 with arrow 12 in FIG. 2).
- Classification takes place in the separation zone (channel 7) and in rotor 2.
- the coarse material leaves the channel 7 via an outlet, not shown.
- the fine material flows through the rotor 2 from the outside inwards and leaves the classifier in the axial direction (arrow 13 in FIG. 1).
- FIGS. 3 and 4 differs from the embodiment according to FIGS. 1 and 2 in terms of the solids supply.
- the housing 1 is equipped with an annular recess 15 which, together with the upper rotor disk 5, forms an annular chamber 16 extending approximately to the outer edge 8.
- the solid or an aerosol (or a suspension) is fed in via a radially inner inlet 17 (arrow 18). On the way out, the goods are accelerated in the circumferential direction. It leaves the chamber 16 via a plurality of openings 19 formed in the rotor disk 5 or its outer edge 8, which open into the separation zone (channel 7) in the illustrated embodiment.
- the openings 19 are designed such that the chamber 15 is initially followed by a line section 20 which extends obliquely outwards and in the direction of the channel 7. This merges into a line section 22 which extends essentially axially parallel and widens into an opening 21 which is elongated in the radial direction.
- FIG. 4 shows a plan view of a part of the underside of the rotor disk 5 or its edge 8. It can be seen that the line sections 22 expand into elongated, approximately oval-shaped orifices 21. In the openings 19, the supplied material receives the peripheral speed corresponding to the radius of the location of the mouths 21
- the solid to be classified is introduced into the classifying area (channel 7) independently of the fluid, with part of the fluid or together with the fluid depends essentially on the properties of the solid. Both exemplary embodiments enable all alternatives. In the embodiment according to FIGS. 3 and 4, there is also the possibility of arranging the orifices 21 to a smaller radius, so that the line sections 19 between the blades 4 open into the rotor 2.
