  • the invention relates to a mixing device for mixing powdery or fine-grained substances with water, in particular building materials, for example gypsum, cement and lime, with water.
  • building materials for example gypsum, cement and lime
  • Mixing devices in which powdery or fine-grained mix is mixed with water are known. These usually have a funnel-shaped conveying container for the pulverulent mixture, a mixing zone connected to the funnel outlet down into which the water is introduced, and a mixing whisk which detects the mixture entering the conveying container through an opening and transports it into the mis zone ,
  • the mixing mixer engages with a drive motor on the conveyor tank side and with a feed pump on the isch 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 to one another by a crossbar on the feed pump side, which is also designed as a driving element for the feed pump and which also ensures the stability of the mixer paddle.

  • a mixing spiral is arranged, which is firmly connected with its delivery pump-side end to one of the two mixing rods and is spiral and. extends upwards into the hopper.
  • BESTATIGUNGSKOPIE DE-A-197 29 196 and DE-A-197 55 059 each have a problem, in which measures are taken to accelerate the mixing process and to improve the mixing result, which relate to its design and spatial extension.
  • at least one auxiliary mixing rod is additionally arranged in the region of the orbit of the mixing rods. This auxiliary mixing rod increases the effectiveness of the mixing process while largely avoiding clumping.
  • the invention consists in the fact that the mixing tool arranged in a mixing zone of a mixing device for mixing powdery substances with water and driven by a drive motor is formed from at least one mixing element which is rotatably coupled to the output shaft of the drive motor at a distance from the axis of rotation of the bearing holder Output shaft is rotatably mounted and performs a rotational movement of the drive element as well as an additional rotational movement about its own axis.
  • the mixing element has a drive wheel, which forms a transmission with the mixing chamber wall serving as the transmission member or with a transmission member arranged non-rotatably relative thereto, through which the drive wheel is driven when the bearing holder rotates.
  • the at least one mixing element moved about this at a distance from the axis of rotation of the drive element and thereby additionally set in rotation already leads to an improvement in the mixing process and to an increase in the conveying capacity of the mixing device.
  • a plurality of mixing elements are arranged at the same distance from one another, so that the mixing process is considerably improved and accelerated, the rotating and rotating mixing elements transporting the material to be mixed to an opening arranged centrally under the mixing zone. This increases the delivery rate.
  • a feed pump can be arranged below the mixing zone.
  • This and the bearing holder can be connected to a drive element coupled to the output shaft of the drive motor.
  • This is advantageously a drive rod of any cross-sectional shape coupled to the output shaft of the drive motor, a square or rectangular cross-sectional shape in particular facilitating the non-rotatable arrangement of the bearing receptacle.
  • such a cross-sectional shape also facilitates a loose coupling of the drive rod with the aid of a driving claw to the output shaft of the drive motor, the loose connection between the driving claw and the drive rod being necessary to enable the same to swing.
  • a slow-running rotary pump can also advantageously be used as the feed pump because the mixing elements rotate faster.
  • the mixing elements ensure that the mixed mixture is transported to the opening arranged with ig or to the suction opening of the feed pump, it is also possible to dispense with a feed pump, so that the drive element can then also be omitted.
  • the concentrically formed gear link can be a ring gear or a roller chain arranged in a ring and the like Drive wheel a gear or a sprocket, which is either inside or outside of the ring gear or roller chain ring with the same in engagement.
  • the roller chain serves as a fixed wheel, such as the outer wheel in a planetary gear, but has the advantage that sprockets and thus also mixing elements can be arranged both on the outside and on the inside thereof.

Abstract

L'invention concerne un dispositif mélangeur pour mélanger des substances pulvérulentes avec de l'eau. Ce dispositif comprend un instrument mélangeur, disposé dans une zone de mélange, et une amenée d'eau, ainsi qu'un moteur d'entraînement disposé au-dessus de la zone de mélange, ce moteur servant à entraîner l'instrument mélangeur. L'objectif de l'invention est d'améliorer ce dispositif de façon à accroître considérablement son rendement tout en maintenant une efficacité de mélange élevée. A cet effet, l'instrument mélangeur est formé d'au moins un élément mélangeur (10, 11) qui est monté rotatif, à distance de l'axe de rotation de l'arbre récepteur (1) du moteur d'entraînement (M), sur un logement d'appui (3) couplé solidaire en rotation à cet arbre récepteur (1). Cet élément mélangeur présente une roue d'entraînement (13, 14) qui forme un engrenage avec la paroi de la chambre de mélange ou avec un élément d'engrenage disposé solidaire en rotation par rapport à cette paroi et conçu de façon concentrique (chaîne à rouleaux doubles (18)). Ainsi, en cas de rotation du logement d'appui (3), l'élément mélangeur (10, 11) tourne avec celui-ci et effectue une rotation additionnelle autour de son axe propre (B, C).
