Definitions

  • the material components can be fed to the mixer as separate streams or as a single stream.
  • each stream can then be divided twice or four times or even more frequently into partial streams, which are then combined with one another in new combinations to form new streams and again divided twice or four times or even more frequently.
  • the vertical sections 58 of the intermediate walls 56 form flow divider walls, against which the individual streams A and B run up and are thereby divided into partial streams.
  • the material component stream A flowing into the upper flow divider chamber 36 flows against the flow divider wall 58, is thereby divided in opposite directions and the partial streams thus formed flow in opposite directions through the side openings 40 into the mixing chambers 42 and 44.
  • the material Component stream B flows in the lower flow divider chamber 34 against its flow divider wall 58, where it is divided into two partial streams flowing in opposite directions, which also flow in opposite directions through side openings 38 into the mixing chambers 42 and 44.
  • the vertical section of FIG. 7 runs in the lowest level 202 behind the partition 260 in accordance with the section information Z-Z in FIG. 8.
  • the vertical section in FIG. 7 runs along the section X-X of FIG. 8.
  • the sectional view of the second floor 203 from below in FIG. 7 runs along the sectional plane Y-Y of FIG. 8.
  • the partitions 260 extend over. the through openings of the shelves 246 and thereby divide these through openings by twice the number, which are designated in FIGS. 7 and 8 with 250/1, 250/2, 252/1 and 252/2.
  • the top floor 308 differs from the underlying floor insofar as about their angularly rotated through 90 0 a ground floor 346 is arranged, but no further floor. It is thereby achieved that even on the top floor 308 the streams are divided into sub-streams, the sub-streams are combined to form new streams and the new streams through the openings 350/1, 350/2 and 352/1, 352/2 of the uppermost serving as a ceiling Floor 346 can flow through.
  • the material component stream flowing through the connecting piece 30 of the nozzle 22 which can consist of two or more components, is divided into four sub-streams A1, A2, B1 and B2, A and B being the original two material components , which are supplied in the connecting piece 30.
  • the passage openings 350/1, 350/2, 352/1 and 352/2 are connected to channels 374 and 375 leading to the flow divider chambers 334 and 336 which are formed on the one hand by vertical legs 376 and 378 of the intermediate wall 356 and on the other hand by side walls 380 and 382.
  • the side walls 380 and 382 run axially parallel to the central axis of the mixer column 346 over the entire height of the mixer column and extend radially to the central axis of this mixer column.
  • the vertical legs 376 and 378 of the intermediate wall 356 are offset in height, but parallel to one another.
  • the legs 376 and 378 and the side walls 380 and 382 each coincide with the edges of the through openings 350/1, 350/2, 352/1 and 352/2.
  • FIGS. 9 to 16 relate to an embodiment preferred over the embodiment according to FIGS. 7 and 8 for a fourfold division and new mixing of the material component flows.
  • FIGS. 1 to 6 relate to a preferred embodiment for the two-way division of material component flows.
