Definitions
- the invention relates to a vertical-axis air classifier with a central good job with tangential air supply arranged at the level of the classifying rotor, with a fixed on the circumference of the classifying rotor arranged at a radial distance Guide vane ring, with a ring-shaped one through one Paddle wheel classifier rotor and a coaxial radial distance to the The outer circumference of the classifying rotor arranged guide vane ring limited Visual space, with a drive shaft for the classifier rotor mounted on one side and a housing with fine and coarse material outlet.
- Such an air classifier in which the material to be viewed is arranged around an axis rotating wheel is set in rotating motion and with one from the outside inward running air flow into which the rotating visible material is added evenly over the circumference of the classifying wheel to the classifying zone known from German Offenlegungsschrift DE 35 21 638 A1.
- the material to be sifted is fed in centrally and spread over a spreading plate distributed and bell-shaped over the outer circumference of the classifying rotor evenly distributed good veil passed past the classifier wheel blades.
- the classifying wheel is flowed through by the classifying air from the outside in and that Fine material directed into the interior of the classifier rotor.
- the rejected coarse material follows gravity continues and is surrounded by an annular coarse material discharge area added.
- the cover plate together with the classifier wheel blades from an extended one, the classifier rotor penetrating part of the drive shaft.
- the disadvantage is that the Inside the classifier rotor does not remain free of internals and therefore the flow in the Inside the classifier rotor is disturbed.
- the classifier In order to be able to clean all areas within the classifier, the classifier must do so be completely disassembled into its individual parts. This is about the distribution of the functional connections such as drive, storage, good feed, fine material outlet and Coarse material escaping through several sides of the classifier housing is particularly difficult.
- the visible material is affected by the action of gravity guided down along the classifier rotor. Except for the radial The material to be sifted essentially moves in turbulence Direction of gravity downwards.
- the visible material is only the sifter offered once and for a short time. Due to the short dwell time of the material to be viewed on the classifier, the fine material cannot be completely diverted from the flow of classifying material and be sighted.
- the rejected coarse material fraction therefore still contains significant proportions of fine grain. The quality of the coarse goods is therefore not optimal.
- the vertical alignment of the classifier and the result in Visible material falling downward is an inconsistent Good concentration in the viewing zone, which means that the entire classifier rotor length is not can be used optimally.
- the additional idea of the invention is the coarse material that has been sighted through a fluidize additional air flow and through a rotating ring disc to transport to the coarse goods outlet.
- An additional, fixed ring prevents the finished coarse material from being returned to the viewing area.
- Fig. 2 shows the cross section of an air classifier according to the invention with a perforated drive shaft.
- the classifying air is supplied through the classifying air inlet 4 behind the guide vane ring 3 .
- the annular coarse material discharge space 13 and the annular fine material discharge space 14 are arranged below the classifying wheel vane ring 9 coaxially with the drive shaft.
- the lower cover plate 15 of the classifying rotor 8 is provided with openings and thereby opens the fine material outlet from the inside of the classifying rotor 8 into the fine material discharge space 14 .
- the Feingutaustragsraum the penetrating portion of the drive shaft 2 as a perforated shaft member, the support means 10 is formed and thereby allows the passage of the fine material from the interior of the separator 8 in the Feingutaustragsraum fourteenth
- This support device 10 comprises the base plate 18 , the washer 17 , and the aerodynamic spacer webs 10a and form a connecting link between the drive shaft 2 and classifier wheel 8 and the passages for the discharge of the fine material from the inside of classifier wheel 8 .
- the classifier wheel 8 consists of the classifier wheel vane ring 9 , the lens 16 and the cover plate 15 and is rotatably connected to the support device 10 .
- This connection in the area of the discs 15 and 17 can be designed releasably and z. B. by screws 19 arranged uniformly over the circumference of the classifying rotor.
- a seal 20 that can be flushed with a fluid is shown in an axial arrangement and reliably separates the visible space 21 from the fine material outlet space 14 .
- the lower cover disk 15 projects beyond the inner diameter of the annular disk 17 , and thus over the support device 10 into the interior, and thus forms an orifice with a throttling effect in the transition area.
- the good feed takes place on the cover plate 16 of the classifying rotor 8 , which forms a diffusing plate.
- the annular channel between the outer diameter of the classifying wheel 8 and the inner diameter of the guide vane ring 13 forms the classifying space 21 over the height of the classifying wheel 8 .
- Visible material flows through the viewing space 21 in the vertical direction.
- a screw spiral 29 extends almost over the entire radial width of the visible space 21 and extends over the entire height of the classifying wheel 8 .
- a single helical screw with a constant pitch is used.
- the sifting air flow runs perpendicular to the sifting material flow.
- the classifying air from the classifying air inlet 22 passes horizontally through the fixed guide vane ring 3 into the classifying chamber 21 and flows through it perpendicularly to the classifying material flow.
- the fine material sighted is discharged axially with the classifying air via the fine material outlet 23 .
- the coarse material sighted is discharged through the coarse material discharge space 13 below the viewing space 21 via the coarse material outlet 24 .
- the coarse material discharge ring 25 is fixedly connected to the classifying wheel 8 and rotates within the coarse material discharge space 13 .
- the fixed retaining ring 26 is arranged above the coarse material discharge space 13 and is firmly connected to the housing 1 .
- the gap 27 for the introduction of the scavenging air 28 is located between the bottom of the coarse material discharge space 13 and the coarse material discharge ring 25 .
