Definitions

  • the present invention relates to a device for homogenizing a liquid mixture, in the form of a cylindrical arrangement of at least two comminution members seated on holders, the outer, stationary comminution member having a ring with slots and the inner, rotatable comminution member having at least two vanes.
  • Such devices have been manufactured and sold under various trade names for decades and are described in a number of patents, including CH-A-466 010, CH-A-604 894 and in particular also in German Utility Model No. 84 28 851, in a guide beam homogenizer is described, which has a high delivery rate and is particularly suitable for homogenizing, breaking up agglomerates in viscous media or quick loosening of salts, resins and the like.
  • FR-A-2 265 444 describes a mixing device for treating and / or mixing flowable media. It has an inner rotor with shredding blades, which rotates inside a ring which is provided with holes and is surrounded by an outer ring, also with holes. The rings are not held against the rotor. The inner ring can be replaced to change the cross-section of the normally aligned holes.
  • stator 1 shows the stator 1 arranged on a holder 11 and the rotor 2 fastened on a shaft 12, wherein generally only the rotor rotates and the stator, as its name implies, is fixed.
  • Slits 4 are arranged on the jacket 3 of the cylindrical stator and are arranged approximately perpendicular to the central axis M.
  • the rotor 2 as described in detail in the German utility model mentioned at the outset, consists of two or more blades 18, the end face or an edge thereof of which is designed as a knife edge.
  • the narrow sides of the slots 4, which open into the interior of the stator, are designed as cutting edges and work together with the edges of the rotor blades in order to act as scissors that can also effectively cut long fibers, for example.
  • the end faces of the rotor form an angle deviating from 90 ° in a known manner with the side faces which are parallel to one another, the inclination of this face being designed such that the cutting edges are in the same direction with respect to a direction of rotation.
  • the rotor blades and the slot broad sides do not need to show any cutting effects.
  • This narrowing of the slots is achieved by arranging a ring 5 above the jacket 3 of the stator, which ring has in principle the same slots 6 as the slots 4, although this is not absolutely necessary.
  • the outer ring is fastened to the stator 1 or holder 11 by means of a screw 7.
  • the device according to the invention is part of a system and is arranged in a vessel 8.
  • the vessel has an inlet 9 at the bottom and an optionally valve-controlled outlet 10 from which the homogenized liquid can be removed.
  • the holder 13 is arranged in a corresponding recess 14 in the vessel so that it can move up and down, as can be seen from the arrow 15. If not shown, the holder can optionally be sealed off from the interior of the vessel via a shaft seal.
  • the outer stator ring 16 is fixedly connected to the vessel via the inlet 9, while the inner stator ring 17 connected to the holder can be moved up and down relative to the outer ring via the optionally motor-driven holder 13, so that the width of the slots 6 and 4 is thereby on the outer or inner stator ring can be changed or precisely adjusted.
  • the remaining features, i.e. the rotor 2 and the rotor shaft 12 and the configuration of the slots are the same as in the exemplary embodiment according to FIG. 1.
  • the holder 13 can also be rotatably driven, if necessary.
