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 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.
- the respective auxiliary mixing rod can be straight and, for example, parallel to the mixing rods. To further increase the effectiveness of the mixing process, however, it can also be wave-shaped in the plane defined by this and the axis of rotation.
- the wave crests of an auxiliary mixing rod can face the wave troughs of a different auxiliary mixing rod. In this way, additional flows are advantageously generated when the mixture is mixed with water, and the mixing is intensified.
- the respective auxiliary mixing rod can have a round, flat or square profile.
- Several 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 a mixing device with an inventive Mixing whisk
- Fig. 3 a section III-III through the mixer.
- the mixing paddle 1 shows a mixing device with a mixing whisk 1 according to the invention for a cleaning machine.
- the mixing paddle 1 has two mixing rods 2 arranged at a distance parallel to the axis of rotation A and in the middle between them at the same distance from the axis of rotation A each an auxiliary mixing rod 2a and a conveyor spiral 3.
- the mixer whisk 1 engages with a flange 4 in a recess of the output shaft 5 of an electric motor 6 corresponding to the latter.
- the mixing bars 2 and the auxiliary mixing bars 2a are connected to one another by a crossbar 8 having a centering pin 7 (FIG.
- the mixing paddle 1 is arranged in such a way that the conveyor spiral 3 is in the area of a feed hopper 10 and the mixing bars 2 are in the area of their parallel arrangement in a mixing zone 11 which connects to the tapered outlet of the feed hopper 10 and into which a pipe 12 for introduction flows out of water.
- the auxiliary mixing rods 2a have an angular distance of 90 ° from the mixing rod 2 arranged in front of them in the direction of rotation and the same orbit as the mixing rods 2.
- the auxiliary mixing rod 2a at the front in FIG. 1 is essentially only formed in the area of the mixing zone 11, while the auxiliary mixing bar hidden in the area of the mixing zone 11 Mixing rod 2a on the drive motor side extends into the feed hopper 10.
- 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, on the transverse rod 8 connecting the mixing rods 2 and are designed as a unit.
- a bend 2b (FIG. 2)
- 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 about a third of its total length outside the mixing rods 2 is arranged (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 ⁇ of substantially 15 ° increasing.
- the conveyor spiral 3 and the crossmember 13 each have a pressure surface 14 or 15 on the conveyor dollies 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 ß of the conveyor rale and the associated inclination of the same results in a cutting edge S p .
- auxiliary mixing rods 2a illustrate the design and arrangement of the auxiliary mixing rods 2a. These are wave-shaped in the plane defined by them themselves and the axis of rotation A, the wave crests of one auxiliary mixing rod 2a being directed opposite the wave troughs of the other.
- auxiliary mixing rods 2a produce additional flows when the material to be mixed is mixed with water, so that it is intensified. 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.
