Definitions

  • the present invention relates to an inclined mixer which is used, for example, to mix building materials, in particular for the production of cement emulsions, foam concrete, color mixes and styrofoam concrete.
  • Said mixer is preferably used for the production of high-quality concrete materials such as self-compacting concretes, ultra-high-strength concretes, mineral cast and all other types of concrete.
  • Such a mixer has an inclined mixing container and can be used, for example, in concrete and chemical plants, but also in the food and feed industries.
  • Such a mixer is preferably designed as a single-shaft mixer.
  • document DE 11 82 036 B discloses a mixer with two shafts that rotate in opposite directions of rotation. Blades are attached to both shafts.
  • a single-shaft compulsory mixer is known, which is inclined by about 45 degrees from the horizontal during the mixing process.
  • This mixer can be tilted further or in two directions for emptying, so that all the material to be mixed can flow out of the mixer and can thus be removed by gravity.
  • Various mixing tools are disclosed for this mixer, for example a screw-shaped mixing tool and mixer blades. In this mixer, the actual mixing is only disclosed in one direction, but the direction of rotation of the mixing tool can also be reversed for emptying the mixing container.
  • This prior art mixer is suitable for a variety of solids.
  • the invention includes a mixer with a mixing container which is inclined with respect to the horizontal.
  • the angle of inclination is preferably 10 ° to 80 °, preferably 15 ° to 70 °, more preferably 30 ° to 60 °.
  • the drive that drives the mixing tool can be operated in two opposite directions, so that it is possible to switch between two directions of rotation of the mixing mechanism.
  • This mixer is also preferably designed as a single-shaft mixer. Such a configuration of the mixer enables shorter mixing times for all types of concrete compared to the prior art, but at the same time the achievement of homogeneous mixtures. This is achieved in particular by the fact that the entire material to be mixed is in motion during the mixing process, since it is pressed by gravitational forces to the lowest point of the mixing container, where it is moved periodically by a mixing tool.
  • the mixing tool comprises a centrally arranged axis and at least one mixing device attached to it, which is preferably also provided with branches.
  • a scraper is arranged, which is adapted to rest with one side on the inside of the jacket of the mixing container and to brush it in one direction of rotation.
  • This scraper also has the function of a mixing tool.
  • the direction of extension of the scrapers is rotated around the direction of the central shaft by an angle which is 10 ° to 80 °, more preferably 15 ° to 70 ° and even more preferably 30 ° to 60 °. This allows a particularly advantageous mixing and scraping action of the scrapers, since the scrapers can convey or move mixed material in the direction in which the central shaft extends. The transverse transport of the mix is thus significantly improved.
  • a mixing device can additionally have a lance which is retractable through an opening into the interior of the mixing container.
  • a lance is connected at one end to a vibration motor and at the other end can be in contact with the mixing tool in order to transmit the vibrations of the vibration motor to this, which allows better cleaning.
  • this is very advantageous for cleaning.
  • nozzles can be provided through which a fluid, for example air, can be introduced. This allows better mixing through stronger turbulence of the material to be mixed. Furthermore, such nozzles allow an improved and faster cleaning of the mixer after use.
  • the mixing apparatus preferably also has a frequency converter which is connected to the drive of the mixing tool and controls its power consumption.
  • the frequency converter prevents the drive from consuming too much power when it starts up. This relieves the load on the drive and therefore has a longer service life. This means that even difficult start-up conditions can be operated without strong overcurrent peaks. Without a frequency converter it would not be possible to change the direction of rotation of the mixing tool when the mixing container is full, or the drive would have to be very large in order to obtain the required power - the power consumption would also increase drastically. Furthermore, without the frequency converter, rapid wear and tear of the drive's gearbox would have to be expected.
  • the frequency converter also ensures that the actual torque of the drive can be regulated between the lowest possible torque (i.e. zero) and the highest possible torque of the drive, which is particularly advantageous when changing the direction of rotation and thus the mixing direction. Targeted control of the drive torque is therefore possible.
  • Using a frequency converter also has the advantage that electricity can be saved. Such a frequency converter is also officially subsidized by the state.
  • one or more agitators can also be provided in the mixing apparatus.
  • These whirlers are additional structures on the mixer, which contain a drive, a whirling shaft and at least one whirling tool.
  • a swirler is arranged on the mixer in such a way that it does not touch the central shaft or the mixing tools and cannot interfere with them.
  • a whirler is particularly advantageous when the material is very difficult to mix.
  • Such a vortex can increase the mixing effect of the mixing apparatus by creating a cross flow.
  • This further embodiment can have at least one, preferably several additional vortices.
  • the cylindrical mixing container 2 is inclined at an angle ⁇ to the horizontal. In the present embodiment, this angle ⁇ is approximately 45 °.
  • the mixing container 2 has both a casing 2a and a base plate 2b.
  • a mixing tool 3 is provided in the middle of the mixing container. This mixing tool 3 has a central shaft 3 a, to which mixing devices 3 b are attached via connecting devices 3 d and which extend from the central shaft 3 a in the direction of the casing 2 a of the mixing container 2.

  • a scraper 5 is arranged at the end of the mixing devices 3b, one side of which rests against the inner wall of the casing 2a of the mixing container 2.
  • the mixing tool 3 a is driven by a drive 4 which is mounted outside the mixing container 2 and which is connected to a frequency converter 12.
  • an opening 6a (not shown here) is provided in the jacket 2a of the mixing container 2, which opening is provided with a closure means 6a.
  • a lance 7, which is adapted to be able to be advanced up to the central shaft 3a and to be in contact with it, can be inserted through this opening.
  • a vibration motor 8 is attached to the lance, which can transmit vibrations to the lance 7 and thus also to the mixing tool 3, so that it can be used after the The mixer is easier to clean.
  • a lower scraper 11 is provided at the lower end of the middle shaft 3a, which sweeps over the bottom plate 2b from the inside in order to clean it if necessary.
  • FIG. 11 shows a sectional view along the line AA from FIG Fig. 1 .
  • a plurality of mixing devices 3b are arranged on the central shaft 3a in this embodiment, two of these mixing devices 3b enclosing an angle ⁇ here.
  • a scraper 5 is arranged at the end of each of the mixing devices 3b and rests against the inner wall of the jacket 2a.
  • FIG. 13 shows a cross-sectional view along the line BB in FIG Fig. 1 .
  • the direction of extension of the scrapers 5 is rotated around the direction of the central shaft 3a by an angle ⁇ .
  • This angle ⁇ is approx. 45 ° here.
  • nozzles 9 are arranged on the bottom 2b of the mixing container 2. These are used to introduce a fluid, for example air, to improve the mixing effect and for cleaning purposes.
  • Fig. 4 shows a view similar to that in Fig. 1 except that a part of the casing 2a is not shown here, so that, so to speak, a view into the interior of the mixing container 2 is possible.
  • the drive 4, the frequency converter 12, the base plate 2b, the lance 7 and the vibration motor 8 are the same as in FIG Fig. 1 .
  • the exact arrangement of the mixer 3 becomes clear here:
  • Several mixing devices 3b are arranged on the central shaft 3a, on which the branches 3c and the scrapers 5 are in turn arranged.
  • the scraper 5 is not arranged parallel to the central shaft 3a, but rotated relative to it (by the angle ⁇ ).
  • the material to be mixed When operating in the reverse direction (R), the material to be mixed is conveyed obliquely upwards and the inner wall of the container jacket 2a is stripped off so that any parts of the material to be mixed which may adhere to it are conveyed back into the interior of the mixing container 2.
  • the frequency converter 12 also allows a simple and energy-saving change in the direction of rotation.
  • Fig. 5 Fig. 13 shows a mixing apparatus of the present embodiment from below.
  • the arrangement of the outlet opening 10 in the base plate 2b of the mixing container 2 is particularly evident here.
  • the arrangement of the nozzles 9 in the base plate 2b of the mixing container 2 is also clear here.
  • the mixing device can be adapted to a particular mixing task, ie the mixing container 2 can be inclined at a very specific angle ⁇ around the horizontal, the mixing devices 3b can be arranged at a specific angle ⁇ from one another, and the angle ⁇ by which the scrapers 5 are rotated about the direction of the central shaft 3a can also vary.
  • the angle ⁇ between two mixing devices 3b can, for example, preferably be 10 ° to 180 °, more preferably 40 ° to 90 °, even more preferably 45 ° to 60 °.
  • FIG. 6 Figure 3 shows an isometric view of another embodiment of the present invention.
  • the mixing apparatus 1 also has a vortex 13 on the jacket 2a, of which the drive 13a and the vortex shaft 13b are shown here.
  • This agitator 13 is preferably arranged vertically on the lateral surface 2a and protrudes into the mixing container 2, the agitator 13 being arranged at those points at which no mixing tool 3 is provided on the centrally arranged shaft (3a).

  • These are flat and plate-like and are attached to the vortex shaft 13b.
  • these whirling tools 13c are arranged in such a way that they are at a distance from the centrally arranged shaft 3a.
  • the two drives 13a are each connected to a vortex frequency converter 13d so that these vortexes can also be driven in both directions and can have the same advantages as the drive 4 for the entire mixer (not shown here).
  • mixing container 2 It is not absolutely necessary for the mixing container 2 to have a cylindrical shape. Rather, conical or frustoconical shapes can also be possible here.
  • the number of mixing devices 3b which is attached to an inner shaft 3a can also vary depending on the mixing task.
  • a plurality of different mixing devices 3b can be attached to the inner shaft 3a.

  • a method for mixing a material to be mixed in a mixing apparatus 1 will be described below.
