Definitions

  • the invention relates to a mixer for a mixing device for powdery or fine-grained mix for mixing with water, in particular for a mixing device arranged in a cleaning machine.
  • 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 down into which the water is fed, and a mixing whisk which the mixed material entered through an opening in the conveying container is captured and brought into the mixing zone.
  • the mixer engages with a drive motor on the conveyor tank side and with a feed pump on the mixing zone side, which 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 around this drive rod.
  • Pump-side end is firmly connected to one of the two mixing rods and extends spirally and opening upwards into the feed hopper.
  • 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.
  • the mixing whisk has two mixing rods arranged essentially parallel to its axis of rotation for a mixing zone formed in the mixing device and a conveyor spiral arranged thereon, which is arranged in a conveying funnel above the mixing zone, and is in a known manner one end with a drive motor and the other end with one Feed pump connected.
  • the two mixing bars are connected by a cross bar that has a centering pin on the feed pump side and is designed as a driving element for the feed pump.
  • the mixing Rods are guided through the conveyor spiral to the drive motor and unite there to form an engagement element for the output shaft of the drive motor.
  • the end of the feed spiral facing the feed pump is fastened to one of the mixing rods and is supported at a distance from this fastening point by a cross-piece connected to both mixing rods.
  • This traverse is arranged in the radial direction, relative to the axis of rotation of the mixing whisk, to the point of connection on the mixing rod to an acute angle to a plane running perpendicular to the axis of rotation and, like the delivery spool, has a pressure surface on the delivery pump side, which is set in the direction of rotation and through which the powdery or fine-grained mix is pressed towards the center of the hopper and the mixing zone.
  • the mixing bars can have a pressure surface on the axis of rotation and a pointed and rounded cutting edge in the direction of rotation at the front, so that they can penetrate the mix better. They can have a pressure surface on the axis of rotation, the direction of rotation being exposed to the outside, preferably at an angle of 15 °, so that the material to be mixed is pressed into the central region of the mixing zone and the mixing process is accelerated.
  • the pressure surfaces of the conveying spiral and the traverse which are set in the direction of rotation, can have an angle of 10 ° to 20 °, preferably of 15 °, with respect to a plane arranged perpendicular to the axis of rotation.
  • the traverse can have a rounded cutting edge in the direction of rotation in order to be able to penetrate the mix better and guide it to its pressure surface.
  • This design of the mixing paddle in which the area of the axis of rotation inside the conveyor spiral is free of components, since the crossbeam is arranged in the upper third of the mixing paddle and thus at a distance above the outlet of the funnel, allows the mix to be accelerated in this central one Area and push down freely. This prevents clumping and clogging, especially in the edge area of the feed spool.
  • the crossbeam arranged at a distance from the mixing zone also contributes to this.
  • this ensures the stability of the mixing whisk, at the same time fixes the conveyor spiral at its free end and also serves as a conveying element.
  • the fact that the mixing rods are also drive rods for the mixing whisk also minimizes the production outlay for the mixing whisk.

Abstract

L'invention concerne un fouet mélangeur (1) pour dispositif mélangeur, comprenant deux tiges mélangeuses (2) disposées à distance, sensiblement parallèlement à son axe de rotation (A) et une spirale transporteuse (3) montée sur lesdites tiges et reliée à une extrémité à un moteur d'entraînement (6) et à l'autre extrémité, à une pompe de refoulement (9). La spirale transporteuse (3) est placée dans la zone d'une trémie transporteuse (10) qui va s'amenuisant en direction de la pompe de refoulement (9) et sous ladite trémie, il est prévu une zone de mélange. L'invention vise à mettre au point un fouet mélangeur (1) qui permette d'accélérer considérablement le processus de mélange et d'en assurer un déroulement fiable dans une large mesure. A cet effet, les tiges mélangeuses (2) sont guidées à travers la spirale transporteuse (3) jusqu'au moteur d'entraînement (6). La spirale transporteuse (3) est fixée par son extrémité qui fait face à la pompe de refoulement (9) sur une des tiges mélangeuses (2) et est soutenue à distance de ce point de fixation par une traverse (13) reliant les deux tiges mélangeuses, ladite traverse étant disposée dans le sens radial vers l'extérieur dans l'angle α, de manière à monter. La spirale transporteuse (3) et la traverse (13) présentent côté pompe de refoulement une surface de pression (14, 15) et sont mises en place dans l'angle β dans le sens de rotation.
