Definitions

  • the present invention relates to a device for the kinematic high-frequency treatment of a substance or mixture of substances according to the preamble of claim 1.
  • a device for the kinematic high-frequency treatment of a substance or mixture of substances according to the preamble of claim 1.
  • Such a device is known from CH-A-604 894, in which still further devices relating to the prior art are treated.
  • CH-A-604 894 With these and other known devices according to the prior art, it is assumed that emulsions and suspensions can be processed or produced with the same devices.
  • Practice in recent years has shown, however, that with the increasing demands, this idea of a universally applicable machine can no longer be maintained.
  • the increased requirements inevitably lead to a separation of the structural design of the apparatus necessary or suitable for the respective intended use, with regard to the physical properties of the material to be shredded.
  • a rotor 1 which runs at high speed within a stator 2, is used to generate the kinematic high frequency according to the prior art mentioned at the outset.
  • the case shown in FIGS. 1, 2 and 3 represents the simplest form of a kinematic high-frequency generator.
  • Several rotor rings can also run within several stator rings with a graduated diameter, and several generators, that is to say stators and rotors, can also run one behind the other be switched.
  • the stator as its name suggests, is generally fixed, it can also be rotatable in special arrangements and then rotate in the opposite direction to the rotor.
  • the gap 6 is double wedge-shaped in this example, the outer surface 7 of tooth 3 of the rotor 1 being straight, while the stator teeth 8 have an inner surface 9, which consist of two partial surfaces 9a and 9b which run towards each other at an obtuse angle and thus, together with the outer surface of the rotor 1, result in wedges tapering towards the center.
  • the inner surfaces 9a and 9b are bounded on the outside by the edges 58, so that each tooth 3 has two outer edges 58. This also applies to all of the following exemplary embodiments. This also applies to most rotor outer surfaces.
  • FIG. 1 shows the same stator ring 5 as in FIG. 2 with the teeth 8 and with the two outer surfaces 9a and 9b, while the rotor 10 is shown as a plate with a rectangular end face 11. Since both the stator teeth 8 and the rotor 10 are formed symmetrically, the direction of rotation, indicated by the double arrow 12, does not matter.
  • FIG. 4b A variant of FIG. 4a is shown in FIG. 4b, in which the teeth 13 have inner surfaces 14 which are slightly cambered and which have approximately the same wedge effect as the teeth 8 in FIG. 4a.
  • the rotor is the same as in Fig. 4a.
  • the rotor is the same as in FIG. 4a, while the stator teeth 15 only have an inner surface 17 which extends in a wedge shape with respect to the outer surface 16, all teeth 15 of the ring gear being arranged in the same direction.
  • Arrow 18 indicates the direction of rotation in the direction of increasing tooth thickness.
  • the stator ring of FIG. 4d is a variant of that of FIG. 4c, in which the inner surface 18 of the tooth 19 does not run in a straight line, but is curved, although it should be noted, see arrow 20, that the direction of rotation of the rotor compared to that of Figure 4c is reversed to achieve the necessary wedge effect.
  • the inner surface 21 of the stator tooth 22 is arranged tangentially, i. H. perpendicular to the radius passing through its center.
  • the wedge effect arises from the fact that the working gap between the effective narrow side 23 of the rotor 10 and the inner surface 21 of the stator tooth always forms an angle, with the exception of the position shown in FIG. 4e, in which the center line of the rotor passes through the center of the Inner surface 21 goes.
  • the direction of rotation of the rotor also plays no role here, since both the effective narrow side 23 of the rotor and the inner surface 21 of the stator are symmetrical.
  • a toothed ring 25 consisting of teeth 24 with a slightly trapezoidal cross section is drawn in as the rotor, the outer surfaces 26 of the teeth being aligned tangentially and even.
  • the teeth 27 of the stator form a variant of the teeth 8 or 13 in that the effective inner surface 28 consists of two concave sides 28a and 28b converging in the middle. Since the inner surface is symmetrical, the direction of rotation of the rotor is irrelevant.
  • the rotor is the same as in FIG. 4f, while the stator teeth 29 have a composite effective inner surface which consists of a flat, tangentially oriented partial surface 29a and an angled partial surface 29b.
  • the stator teeth 29 have a composite effective inner surface which consists of a flat, tangentially oriented partial surface 29a and an angled partial surface 29b.
  • Fig. 5a-5g indicate that the reversal of the tooth shapes of the rotor and stator teeth is entirely possible within the scope of this invention.
  • Fig. 5a largely corresponds to Fig. 4a in that the stator teeth 31 are slightly trapezoidal with an effective inner surface 32 which is arranged tangentially.
  • the teeth 33 of the rotor ring 34 have the same effective surface 36 as the teeth 8 in FIG. 4a. The effect is essentially the same and the sense of rotation is irrelevant here.
  • FIG. 5b is the same as in FIG. 4b and has the same stator teeth 31 and rotor teeth 7 which correspond to the stator teeth 13 in FIG. 4b.
  • FIG. 5c corresponds accordingly to FIG. 4f and has the stator teeth 31, while the rotor teeth 38 correspond to the stator teeth 27.
  • the arrangement according to FIG. 5d largely corresponds to the arrangement 4e and has the stator teeth 31, while the rotor teeth 39 with their effective outer surface 40 have a similar mode of operation as the rotor teeth with the active outer surface 23.
  • FIG. 5e largely corresponds to that of FIG. 4c with the stator teeth 31 with a tangentially arranged effective surface 32, while the effective outer surface 41 of the rotor teeth 42 forms an angle with respect to the effective inner surface 32 of the stator teeth.
  • this arrangement is particularly suitable for processing liquid / liquid mixtures, while the direction of rotation should advantageously be reversed for processing solid / liquid mixtures.
  • the arrangement according to FIG. 5g corresponds to the arrangement according to FIG. 4g, the effective outer surface 47 of rotor tooth 48 consisting of a tangentially arranged partial surface and an angled partial surface, as in the case of stator teeth 29 from FIG. 4g.
  • a solid / liquid mixture can also preferably be processed here.
  • FIG. 6a-6e various rotor shapes are shown as a selection, while the stator 2 in the present exemplary embodiment according to FIG. 6 is always the same. As can be seen, all shapes according to FIG. 6 are shown in section.
  • Figure 6a shows one of the simplest forms of a rotor, i. H. Rotor 10 according to FIGS. 4a-e. This rotor shape is also shown in a top view in FIG. 7a, this rotor having four edges 10a of identical design.
  • the rotor 49 according to FIG. 6b can also be used as a modification thereof, which additionally has tips 50 at the bottom which taper to a point.
  • the rotor 3 according to FIG. 6c largely corresponds to that of FIG. 3 and can also be used instead of rotor 10.
  • FIG. 6d in variation to the rotor 3 from FIG. 6c, a rotor 51 is indicated, which has recesses 52 on its outside in order to increase the cutting effect.
  • FIGS. 6b and 6d shows a combination of the shapes from FIGS. 6b and 6d, rotor 53 having the recesses 52 and the tips 50.
  • FIG. 7a, b, c, d different cross sections of the rotors are indicated, with a rhombic cross section of rotor 54 in FIG. 7b, a tapering cross section of rotor 55 in FIG. 7c and with rounded narrow sides 56 in Rotor 57 in Fig. 7d.
