  • Plastering machines in use with a mixing device in which powdery or fine-grained mix is mixed with water, have a funnel-shaped conveying container for the powdery mix, a mixing zone connected to the funnel exit at the bottom, into which the water is fed, and a mixer , which detects the mixed material entered through an opening in the conveying container and brings it into the mixing zone.
  • the mixing whisk is in turn engaged on the conveyor tank side with a drive motor and on the mixing zone side with a conveyor pump that pumps the mixed material into a pipeline.
  • the feed pump is usually a screw pump and rotates simultaneously with the mixer.
  • the mixing paddle has two mixing rods arranged parallel to its axis of rotation in the mixing zone, which extend as far as the feed pump and are connected on the feed pump side by a cross rod that has a centering pin and is also designed as a driving element for the feed pump, which also ensures the stability of the mixing paddle.
  • the mixing rods are connected to one another at their upper end in the region of the feed hopper outlet with a crosspiece, on which a drive rod guided through the feed hopper is fixedly arranged, which is in engagement with the drive shaft of the drive motor.
  • a mixing spiral is arranged, which is firmly connected with its end on the delivery pump side to one of the two mixing rods and extends spirally and opens upwards into the delivery funnel.
  • the mix fed into the feed hopper is gripped by the rotating spiral and, with its support, is brought down into the mixing zone and mixed there with water which is introduced through a lateral pipeline.
  • clumps and consequently blockages can occur, in particular due to insufficient mixing, so that the mixing and conveying process of the mixed material is considerably disturbed.
  • this additional auxiliary mixing rod which is arranged in such a way that the mixing zone inside the orbit of the mixing rods remains free of components, it is possible to mix the mixed material with water at an accelerated rate and to remove clogged, non-humidified or slightly humidified mixing areas as far as possible. This also prevents blockages in the conveying process of the mixed goods.
  • At least one auxiliary mixing rod is arranged between each of the mixing rods and if the angular distance of the auxiliary mixing rods from the mixing rods is approximately 90 °, because this means that the distance between the rods is always the same and the effect of the auxiliary mixing rods on the mixing is optimized.
  • the auxiliary mixing rods or the auxiliary mixing rod is arranged very close to a mixing rod, ie at an angular distance of less than 45 °, the improvement in the mixing process is noticeably reduced.
  • the respective auxiliary mixing rod is formed over the entire area of the mixing zone and extends on the drive motor side into the area of the conveyor spiral in order to intervene in the mixing process as early as possible and to be able to act on it for the entire duration.
  • the auxiliary mixing rod can be held by means of bends on the base of the mixer, preferably in such a way that it is angled towards the axis of rotation at one end connecting the mixing rods at its end at the end of the feed pump and a centering pin for the feed pump having transverse rod is arranged and at its end on the drive motor side via a bend on a mixing rod or a connecting cross-member.

In this way, the mixing process is accelerated and lumps in the edge region of the feed hopper 10 and the mixing zone 11 and also in the region of the cross member 13 are largely prevented.

Abstract

L'invention concerne un fouet à mélanger pour mélangeur, comportant deux barres de mélanges disposées à une certaine distance l'une de l'autre, sensiblement parallèlement à son axe de rotation, et une spirale transporteuse disposée sur lesdites barres. Ce fouet à mélanger est relié, à une extrémité, à un moteur d'entraînement, et, à l'autre extrémité, à une pompe d'alimentation. La spirale transporteuse est disposée dans la zone d'un entonnoir d'alimentation dont le diamètre se réduit en direction de la pompe d'alimentation, et le mélangeur présente, en-dessous de l'entonnoir d'alimentation, une zone de mélange dans laquelle débouche une conduite tubulaire servant à l'introduction d'eau. On obtient ainsi un tel fouet à mélanger dont l'efficacité de mélange est sensiblement élevée et avec lequel la formation de grumeaux est évitée au maximum. A cet effet, une barre de mélange auxiliaire (2a) est disposée dans la zone de l'orbite des barres de mélange (2), et entre celles-ci. Cette barre de mélange auxiliaire est disposée avec un écart angulaire qui est sensiblement de 45° à 135° par rapport à la barre de mélange (2) placée devant elle, dans le sens de rotation.
