Definitions

  • the invention relates to a sifter for the sighting of granular Well, with a static cascade classifier as a custody chamber, the at least one rotatably arranged in the classifier housing, Bar cage provided with turbo elements on the rotor circumference downstream of the dynamic classifier section, with inlets for classifying air / classifying gas and visible goods and outlets for classifying air / classifying gas, fine material, Medium and coarse material.
  • From DE-A-42 23 762 is a classifier with an inside a common view housing housed static sifter part without moving components and a dynamic separator with rotating Bar basket known.
  • the static separator part is a custody chamber for the separation of the coarse grain fraction contained in the grained Good to be seen formed with two of the shaft-shaped classifier housing enclosed and between them a visual zone forming and of the Viewing air in crossflow flowed through visual zone boundary walls, the obliquely downward towards the discharge opening for the selected Coarse grain fraction inclined cascading or arranged like a jalousie Have baffles, wherein the two Leitblechand and thus the between lying visual zone with a deviating from the vertical Angle are arranged obliquely.
  • V-classifier Because in the static separator part the Visual air experiences a V-shaped deflection, this is also referred to as a so-called V-classifier.
  • V-classifier switched on z. B. in a Kreislaufmahlstrom with a Gutbettzerklein mecanics roller press or roller mill, has been chosen for energy-saving views and deagglomerating the ground material in a single operation proven.
  • the invention is therefore the object of a sifter the generic type with static separator part and immediately downstream dynamic separator part arranged with at least one rotatable Bar basket in such a way that the two sifter parts optimally can be operated economically in concert, in particular with moist visible goods, namely the static V-classifier as a precautionary and if necessary dryer and the dynamic separator as an instrument for Finishing and, if necessary, residual drying.
  • Characteristic of the separator device according to the invention is that of Intermediate area between the static part and the dynamic part the separator device bypasses a bypass line via which a partial flow of the static sifter leaving the static sifter part or sight gas flow, For example, deducted in an amount of about 20 to 80% is, so that only a smaller amount of reformulation / reformgas in the downstream dynamic sifter part with the bar cage passes, the can be dimensioned smaller.
  • the contained in the bypass current Solid material which is a mixture of medium and fine material is separated from the bypass stream in an external solids separator and it may represent another product of the classifier.
  • the bypass line of go off the top of the classifier housing, and the solids separator for the bypass line can then be arranged above the sifter be, wherein the Feststoffaustragstechnisch the solids separator with Advantage is introduced from above into the dynamic separator part. It exists but also the possibility of the solids discharge of the external Feststoffabscheiders partially or wholly into the static separator part. It is also possible to use the bypass line instead of the top to let go of a side wall of the classifier housing and the solids separator for the bypass line possibly below the dynamic To arrange sifter parts.
  • the sizing device shown essentially in vertical section 1 shows a V-shaped shaft-shaped housing 10 with two enclosed by the classifier housing and one between them Visual zone 11 forming and of classifying air 12 and hot gas as Drying gas approximately in cross-flow flow through visual zone boundary walls, which slopes downwards towards the discharge opening 13 for the selected coarse grain fraction 14 inclined cascade-like or louver-like arranged baffles 15a and 15b, these two baffle walls and thus the between them lying viewing zone 11 with a deviating from the vertical Angle are arranged obliquely.
  • the goods to be sighted 16 is in the Guteintragsö réelle 17 at the Top of the static cascade sifter introduced.
  • the material to be sighted is sighted in cross flow and good agglomerates are simultaneously deagglomerated.
  • moist visible goods 16 such.
  • B. wet cement raw meal this is effective at the same time dried when a hot gas is used as the visual medium becomes.
  • the baffle walls 15a and 15b can also be perforated Sheets such as screen plates, etc. are used.
  • the middle grain fraction 22 is discharged via at least one of both end faces of the rotating rod basket 19 by the arrow 23, visual air / classifying gas fine material stream drawn off and for the purpose of separating the fine finished good to a not shown Dedusting device out.
  • the bypass line 18, via which a partial flow of the classifying air of the Viewing gas laden with solids is withdrawn, where it is in the solids, a mixture of a fine grain fraction and Mittelkornfr bankruptcy acts leads to a separator 24 for separating the solids 25 contained in the bypass gas stream, from above via line 26 into the dynamic separator section for the purpose of finishing and if necessary, residual drying can be introduced. But there is also the Possibility of solids 25 via line 27 as a separate product deducted.
  • the solids 25 can also be partially or completely via line 28 into the material feed opening 17 of the static sifter part be introduced.
  • the solids separator 24 may be a separator cyclone, a dust filter, a sifter or to act a different classifier.
  • the bypass line 18a is not as in Fig. 1 from the top of the classifier housing 10, but from the left housing 30 about below the bar basket 19. There is also the possibility of reintroduction in this version of the withdrawn via the bypass line 18a solid in the dynamic and / or the static separator part, as shown in Fig. 1 and described.
  • lock 21 for the discharge of the medium grain fraction 22 from the dynamic separator part can be a screw, an air conveyor trough, a vibrating trough or a pneumatic one Extraction etc. are used.
