Definitions

  • the invention relates to an apparatus and a method for continuous casting and granulation of strands of thermoplastic material with a nozzle head having a plurality of nozzle openings having a maximum diameter of 4 mm, and a water-wetted guide (6) for cooling and guiding the plastic strands After the nozzle opening via feed rollers to the entrance of the cutting unit for crushing the plastic strands in granules of about 2 - 3 mm in length.
  • the problem is solved constructively by a special design of the device mentioned above, which is characterized in that the flow rate of the melt with cooling of the strands of the nozzles on the guide to the feed rollers of the cutting of at least 100m / min in the spatially middle region of the nozzle openings is increased so that the cutting unit cuts the strands with a cutting frequency of> 2000 cuts / s.
  • the process used here is characterized in that the strands emerging from the nozzle openings due to a small nozzle opening, namely a maximum of 4 mm, a high velocity gradient in the region of the nozzle openings from the inner surface of the nozzle openings to the inner area at a flow rate of at least 100 m / min, with the result of a strong stretching of the plastic strands on the surface and thus a rapid crystallization in this area and a further stretching of the plastic strands due to the drawn at high speed in the granulator strands with the result of further stretching the surface of the plastic strands and their Crystallization to the granulator, due to the high feed rate while maintaining the max.
  • Length of the granules of about 3 mm the plastic strands with a very high cutting frequency of> 2000 cuts / s to granules cuts.
  • Figure 1 shows the basic design of an apparatus for producing plastic granulate as shown in the German patent application DE 19739747.6, but with after the nozzle outlet straight course of the plastic strands and straight-line guidance of the granules / water mixture.
  • Figure 2 shows the behavior of the plastic in the course of the strand formation to the granulator.
  • Figure 1 shows a side view of an apparatus for granulating plastic strands, as shown and described in principle in DE 19739747 A1.
  • the plastic strands 4 emerge from a nozzle head 1, in which only one nozzle opening 2 is shown for reasons of simplification of the illustration. From the nozzle opening 2 exits a plastic strand 4, which is initially directed to a start-up flap 5 and is directed by this on the guide 6, to which the spray nozzles 7 are directed for spraying cooling water.
  • the feed rollers 8 and 9 then direct the strands 4 to the cutting unit 10, which is formed in a known manner as a knife roller and the strands 4 cuts with a cutting frequency of> 2000 cuts / s to granules, then from the pelletizer housing 11 vertically down as Granules 12 is discharged.
  • Figure 2 shows a schematic diagram of a strand 4 from the area of the nozzle assembly 1 with the passage through the nozzle 2, then the nozzle 2 leaving strand 4 until its processing by the cutting unit 10. From this illustration it can be seen that a to explain the operation the device has arbitrarily excised volume segment 12a in the area in front of the nozzle 2 has a certain relatively large diameter, which is stretched substantially in the longitudinal direction at the entry of the strand 4 and thereby losing diameter, as can be seen on the corresponding volume segment 12b, to which the volume segment 12a has deformed. In this shape of the volume segment 12b, this migrates through the nozzle opening 2, wherein it is exposed to a considerable stretching on its surface.
  • the strand 4 expands again, whereby the respective volume segment 12c, to which the volume segment 12b has now been transformed, has increased in thickness, but without the effect of crystallization on its surface due to the effect of Has narrowed in the nozzle opening 2 lost.
