Definitions

  • Compulsory mixer especially as a concrete mixer
  • the invention relates to a compulsory mixer for the production of mixtures of liquid, powdery and granular components such as e.g. Concrete mixtures.
  • Such a mixer is known from DE 31 10 437 A.
  • the outer agitator is designed as a worm gear, which is set into a movement rotating around the wall of the mixer container.
  • the inner and outer mixer screw convey upwards.
  • the object of the invention is to provide a mixer of the type described above, which is particularly suitable as a concrete mixer.
  • a compulsory mixer which is characterized in that the outer agitator has mixing coulters or scrapers which coat the surface of the mixing container touched by the material to be mixed. While the screw of the internal agitator conveys the material upwards, the coulters or scrapers move the material essentially horizontally. This causes it to flow more quickly, and there is complete mixing and no quiet zones in the entire mixing container.
  • the centrally running screw agitator conveys the mix in a vertical direction, whereby the mix conveyed by the screw experiences a rotational movement.
  • the outer agitator agitator works against this rotational movement.
  • Another advantage of the compulsory mixer according to the invention is that an outlet funnel is dispensed with, since the mixing space can correspond to the outlet of the conventional outlet funnel, on which a rubber hose, e.g. can be flanged for truck mixer filling.
  • the screw agitator extends right in front of the slide, which is attached to the end of the discharge funnel, in order to avoid unmixed zones in the mixer.
  • FIG. 2 shows a detail from FIG. 1 with a sectional detail illustration of a scraper
  • Fig. 3 shows a course of the worm of the inner agitator in top view and side view.
  • an agitator 2 is mounted in the central axis 3 of the mixing container 1, which consists of a shaft 4 and a cylindrical or conical screw 5 or vanes arranged in a helical shape attached to it.
  • This agitator 2 extends directly to the Lock slide 6 and is driven on the opposite side by a drive 7.
  • a second agitator with mixing arms 8 and paddles 9 attached to it, which sweep the surface of the mixing container 1 touched by the mix, is mounted coaxially with the agitator 2 and driven by the drive 10.
  • Both drives 7 and 10 can also be designed to be infinitely variable, the direction of rotation of which is normally selected so that the mixture flows caused by them are directed in opposite directions.
  • the drives 7 and 10 and the mixing container 1 are fastened to a supporting structure 11, which in turn is connected rigidly or via rubber-elastic pads 12 to the system 13 when a vibrator 14 is to be used on the mixing container 1.
  • the mixing container is sealed at its outlet end with the aid of a seal 17 and the closure slide 6 actuated by adjusting element 15.
  • a pipe or hose 16 is used to transfer the mixed material into the transport container.
  • FIG. 2 shows an exemplary embodiment which shows that it is a cuboid body which has a first effective side surface 20 in the circumferential direction and an effective surface 21 in the opposite circumferential direction, the two surfaces 20 and 21 extend essentially in the radial direction.
  • This embodiment has the advantage that the outer agitator can be moved in both directions of rotation and that material pushes off the wall.
  • the mixing arms 8 are designed det that the coulters adapt with their bottom of the container wall surface facing the direction of the wall.
  • the mixing arms 8 and the coulters 9 are adjustable for this purpose in the vertical direction and at an angle to the container wall.
  • the second agitator is preferably moved in intervals, first in one direction of rotation and then in the other direction of rotation. This ensures that unmixed material that is pushed in front of the coulters is quickly mixed in.
  • Additional cutting elements 17 are preferably attached to the screws in each screw plane, which can be attached in the plane of the screw or, as indicated in FIG. 3 above, inclined towards the screw plane. These cutting elements 17 are used to break up lumps of material in difficult mixing processes and to produce a homogeneous mixture.

Abstract

L'invention concerne un malaxeur à mélange forcé pour mélanger des constituants, qui comprend une chambre de mélange sous forme de trémie, dans l'axe médian (3) duquel sont montés coaxialement un agitateur intérieur et un agitateur extérieur. L'agitateur intérieur (2) comprend une vis sans fin (5) qui s'étend jusqu'au tiroir d'évacuation (6). Afin que ledit malaxeur à mélange forcé puisse notamment s'utiliser comme bétonneuse à haut rendement, l'agitateur extérieur (8) présente des lames mélangeuses ou des racles (9) qui balaient les surfaces (1) du récipient mélangeur en contact avec le produit mélangé.
