Definitions

  • the invention relates to a mixer for a mixing device for powdery or fine-grained mix for mixing with water, especially for one in one Plastering machine arranged mixing device, as shown in WO-A-9902249 published on January 21, 1999 with the priority of July 9, 1997.
  • Plastering machines in use with a mixing device in the powdery or fine-grained mix is mixed with water, have a funnel-shaped Conveying container for the powdery mix, one mixing zone connected to the funnel exit at the bottom, into which the water is introduced, and a mixing whisk on that through an opening in the hopper entered mix is recorded and brought into the mixing zone.
  • the mixing whisk is in turn on the delivery container side with a drive motor and with a mixing zone Feed pump engaged, which the mixed material into a Pipeline pumps.
  • the feed pump is common a worm pump and rotates simultaneously with the Mixing whisk.
  • the mixing whisk assigns two in parallel in the mixing zone mixing rods arranged at a distance from its axis of rotation, that extend to the feed pump and on the feed pump side through a centering pin and at the same time trained as a driving element for the feed pump Cross bar are connected to each other, which is also the Ensures stability of the mixing whisk.
  • the mixing sticks are at their upper end in the area of the hopper exit connected to each other with a crossbar which is a drive rod guided through the feed hopper is fixedly arranged with the drive shaft of the drive motor is engaged.
  • a mixing spiral is arranged, with its delivery pump side End with one of the two mixing sticks connected and spiraling and opening upwards extends into the hopper.
  • the mixed material entered in the feed hopper is from of the rotating spiral and with their support brought down to the mixing zone and there with water introduced through a side pipe is mixed.
  • it can be dependent of the mix and the amount of water introduced Clumping and consequent constipation, in particular by insufficient mixing, so that the mixing and conveying process of the mixed good considerably is disturbed.
  • This task is for a mixing whisk according to the generic term of claim 1 by the characterizing features solved.
  • two mixing rods arranged essentially parallel to its axis of rotation and a mixing spiral arranged on the latter, which is connected at one end to a drive motor and at the other end to a feed pump additionally has at least one auxiliary mixing rod according to the invention , which is arranged in the region of the orbit of the mixing rods and which is at an angular distance of essentially 45 ° to 135 ° to the mixing rod arranged in front of it in the direction of rotation.
  • the respective auxiliary mixing stick is over the entire range the mixing zone and extends on the drive motor side into the area of the conveyor spiral in order to in this way as early as possible in the mixing process intervene and act over the entire duration of the same can.
  • the auxiliary mixing rod can be bent on Main body of the mixing whisk, preferably such that it mediates at its delivery pump end a bend directed towards the axis of rotation on one the mixing rods at their feed pump end connecting and a centering pin for the feed pump having transverse rod is arranged and on its drive motor side End over a bend on one Mixing rod or a connecting crossbar.
  • the respective auxiliary mixing rod can be straight and, for example be formed parallel to the mixing rods. To further increase the effectiveness of the mixing process However, it can also pass through this and the axis of rotation defined plane be wavy.
  • the wave crests can of an auxiliary mixing rod each of the troughs face another auxiliary mixing stick. To this way, additional flows are advantageous the mixing of the mix with water, and the mixing is intensified.
  • auxiliary mixing rod in a wave shape and an opposite one in a straight line.
  • the respective auxiliary mixing rod can have a round, flat or square profile.
  • auxiliary mixing bars can also be connected to form a module that can be used as a retrofit unit in conventional mixing whisks.
  • Fig. 1 is a mixing device with an inventive Mixing whisk 1 shown for a cleaning machine.
  • the mixing whisk 1 has two parallel to the axis of rotation A im Spaced mixing bars 2 and in the middle between this at the same distance from the axis of rotation A in each case an auxiliary mixing rod 2a and a conveyor spiral 3.
  • the mixer whisk 1 engages with a flange 4 into a recess of the output shaft corresponding to this 5 of an electric motor 6.
  • the mixing rods 2 and the auxiliary mixing rods 2a through a crossbar having a centering pin 7 (FIG.
  • the stability of the Mixing whisk 1 ensures and at the same time as a take-along element for the feed pump 9, a screw pump known Design, so acts as a drive element for this.
  • the Mixing whisk 1 is arranged so that the conveyor spiral 3 in the area of a feed hopper 10 and the mixing rods 2 in the area of their parallel arrangement in one Mixing zone 11 are located at the tapered exit of the feed hopper 10 connects and into a pipe 12 flows into the introduction of water.
  • the auxiliary mixing sticks 2a have in this arrangement to that in the direction of rotation each in front of these arranged mixing rod 2 Angular distance of 90 ° and the same orbit as the mixing rods 2.
  • the auxiliary mixing rod 2a located at the front in FIG. 1 is essentially only formed in the area of the mixing zone 11, while the auxiliary mixing rod 2a hidden in the area of the mixing zone 11 projects into the feed hopper 10 on the drive motor side.
  • the auxiliary mixing rods 2a are fastened at their end on the delivery pump side via a bend 2b (FIG. 2), which is directed radially to the axis of rotation A, to the crossbar 8 connecting the mixing rods 2 and are designed as a unit.
  • the end on the drive motor side they are each firmly connected to a mixing rod 2 by means of a bend 2c. In this way, a mixing cage is formed in the area of the mixing zone 11.
  • the mixing rods 2 are guided through the conveyor spiral 3 to the output shaft 5. With its end facing the feed pump 9, the feed spiral 3 is welded to one of the mixing rods 2 and is supported at a distance from this fastening point by a crossbar 13 connected to both mixing rods 2 (welded connection), which is arranged outside the mixing rods 2 for about a third of its total length L. is (Fig. 2).
  • This traverse 13 is arranged in the radial direction to the connection point to the conveyor spiral 3 with respect to the perpendicular to the axis of rotation A - or the plane running perpendicular to the axis of rotation - at an angle a of substantially 15 ° increasing.
  • the conveyor spiral 3 and the crossmember 13 each have a pressure surface 14 or 15 on the delivery pump side, which are respectively set at an angle ⁇ of essentially 15 ° in the direction of rotation (indicated by the arrow).
  • the mixing rods 2 also have a pressure surface 16 on the axis of rotation, which is flared outward at an angle ⁇ of essentially 15 ° in the direction of rotation (FIG. 3).
  • the cross member 13 and the mixing rods 2 are provided with a rounded cutting edge S in the direction of rotation, as can be seen from FIGS. 1, 2 and 3. Due to the angle of attack ⁇ of the conveyor spiral and the associated inclination thereof, a cutting edge S F also results on this.
  • FIGS. 2 and 3 illustrate the design and arrangement the auxiliary mixing rods 2a. These are in the plane that defined by this itself and the axis of rotation A, wavy trained, the wave crests of one Auxiliary mixing rod 2a the troughs of the other are opposed.
