Definitions
- the invention relates to a cyclone sifter according to the preamble of claim 1.
- DE-B 10 90 940 is a centrifugal dust separator known, the features of the preamble of claim 1 and in particular has feed channels which are tangential to the Separation room are introduced.
- the channels rise at an angle from bottom to top before they open into the separation area. Details, such as the mouth of the feed channels in the Separation space is formed, DE-B 10 90 940 are not too remove.
- a cyclone separator from EP 398 864 A2 known to separate at least one solid or liquid Substance from a liquid or gaseous medium by centrifugal forces.
- the invention has for its object a cyclone sifter specify with the features of the preamble of claim 1, which with a very simple construction is a very good sighting of the visible material can be achieved.
- the Channel has an area formed as a spiral channel is that the viewing space rises diagonally from bottom to top and flows in a spiral loop into the visual space, and that the spiral channel in the looping area towards the viewing area is open.
- the channel becomes a spiral in the visual space directed upwards and causes that by the Gravity-sinking visible material is repeatedly conveyed upwards is and thus remains in the visual space for a long time. Thereby it is possible to separate the visual goods more precisely what has a positive effect, especially in the middle faction area.
- the coarse material is transferred to the Housing wall crowded and sinks there, while the fines flows out with the classifying air in the central area of the classroom.
- the cyclone classifier has a housing 1 on, which delimits a viewing space 2 in which the visible material by centrifugal forces due to the different weight of the individual particles of the material being sighted.
- Spiral channels 3 and 4 are provided which are diametrically opposed to each other opposite each other and running from bottom to top at 3 'or 4' open into the visual space, whereby they the visible air and the Issue a movement component against gravity.
- the visible material can be shared supplied with the visual air through channels 3, 4 will.
- the visible material can also be passed through channels 5, 6, that open in the area of the upper end of the viewing space 2, are supplied and via a spreading plate 7, which has a Shaft 8 is mounted in the housing 1 and driven by this will be brought into the viewing room 2.
- a spreading plate 7 which has a Shaft 8 is mounted in the housing 1 and driven by this will be brought into the viewing room 2.
- the visible material with the Channels 5, 6 and the spreading disc are supplied with visible air 7 of course not available.
- An immersion tube 9 projects into the viewing space 2 from below Mouth 10 is arranged radially centrally in the viewing space 2.
- the Dip tube 9 can, as shown in Fig. 1, one piece be curved below the mouth 10 and laterally from the Housing 1 are brought out. About the dip tube 9 is Clear air and fines are removed.
- the coarse material sinks at the Outer wall of the housing 1 through an approximately annular space 11, which is formed between the dip tube 9 and the housing wall 1 is down and is via a discharge opening 19th dissipated.
- a guide device is located on the dip tube 9 in the region of its mouth 10 12 arranged.
- the guide device 12 is a conical one Sheet metal ring that with its upper edge with smaller Diameter attached to the outside of the dip tube 9 gas-tight is, whereas its lower edge is larger in diameter protrudes all around from the outer peripheral surface of the dip tube 9. This guide device 12 has the following effect:
- the guide device 12 hardly changes the Peripheral speed (flow conditions) and thus the Centrifugal forces in the viewing area 2 in the approximately annular space 11 by the curved lead out Dip tube 9 occurring flow disturbances from the viewing area 2 shielded.
- the guide ring 13 has the shape of a top and bottom tapered jacket of a truncated cone and is gas-tight with its upper edge with a larger diameter attached to the inside of the housing wall 1, whereas be lower edge with a smaller diameter compared to the edge of the Housing 1 is offset inwards.
- the guide ring 13 is thus from the wall of the housing 1 downwards and inwards.
- baffles 20 are attached, which inwards protrude the viewing space 2. These baffles 20 contribute to one Rinsing the visible material flung against the housing wall 1 at, which in particular the finer visible material back in the visual space 2 is carried back because the space between the Baffles 20 from that fed through the channels 3, 4 Visible air is flushed out.
- the baffles 20 extend as shown in Fig. 1 only on a single baffle 20 is, either over the entire height of the viewing space 2 to Guide ring 13 down or just about the height of merging channels 3, 4.
- a number of guide vanes 14 may be provided, which on Dip tube 9 in the area of the transition of the viewing space 2 in an outflow chamber 15 are arranged.
- the outflow space 15 is the space that is approximately in the axial extension of the dip tube 9 extends upwards.
- the guide vanes 14 are, as can be seen in FIG. 7, in the Cross-section curved and can preferably be adjustable, to the respective circumstances, especially the flow rate to be able to adapt. Through the guide vanes 14 ensures that the classifying air with the fine material largely undisturbed from the rotating in the radial direction of movement and can go further into the axial, whereby the flow resistances decrease, which in turn affects the necessary energy use has a positive effect.
- the guide vanes 14 can be arranged so that they extending from the opening 10 of the dip tube 9 upwards incline towards the main axis 16 of the cyclone sifter, whereby the Transition of the flow from the radial to the axial direction is further improved.
- a classifier wheel 17 with blades can also be used 18 can be provided to the coarse material even better from the fines separate.
- the classifier wheel 17 rotates outside the guide vanes 14 and extends substantially over the entire Height of the viewing area 2.
- the invention can be as follows, for example being represented:
- the cyclone classifier has a housing 1, which approximately one encloses rotationally symmetrical viewing space 2, and one Device 3, 4 for supplying visual air and optionally Visible material in the viewing space 2, which is approximately tangential in the viewing space 2 flows.
- the cyclone classifier also has an outlet 19 for coarse material and an immersion tube 9 for removing the visual air with Fine goods on.
- the device for supplying visual air is formed by two channels 3, 4, which spiral around the The main axis 16 of the cyclone sifter is curved into the viewing space 2 flow into.
