Definitions

  • the invention relates to a mixing device according to the preamble of claim 1.
  • a mixing device of the type required in the preamble of claim 1 is known from DE-PS 21 10 047.
  • the drive motor of the agitator is attached to the second container part, the agitator shaft being in a vertical position in the mixing position.
  • the invention has for its object to further develop a mixing device of the type mentioned in the preamble of claim 1 in such a way that the design is simplified and at the same time the mixing effect is improved.
  • the existing horizontal arrangement of the agitator shaft in the solution according to the invention also leads to a substantial intensification and Improvement of the mixing effect and thus a reduction in the necessary mixing times.
  • the mixing device schematically illustrated in FIGS. 1 and 2 contains a mixing container which consists of two bowl-shaped container parts 1 and 2.
  • the first container part 1 provided with a bottom outlet 3 is designed to be transportable and can be moved, for example, by means of a carriage 4.
  • the second container part 2 is mounted on a stationary holder 5 so as to be pivotable about a horizontal axis 6.
  • the second container part 2 is carried by a hollow shaft 7, which is mounted in bearings 8 in the holder 5 and is connected to a rotary drive (motor 9), which is only indicated schematically.
  • an agitator Arranged in the second container part 2 is an agitator which, in the exemplary embodiment shown, consists of three groups 10, 11, 12 of four mixing tools each evenly distributed over the circumference.
  • the mixing tools of groups 10 and 12 are identified by 13, 14, 15 and 16 and the mixing tools of group 11 by 17, 18, 19 and 20, for example.
  • the mixing tools 13 to 20 have triangular mixing blades (e.g. 21) at their ends, which are arranged such that the tip of the triangular mixing blades points in the direction of rotation (arrow 22) during the mixing process.
  • the hubs 23, 24 and 25 of the three groups 10, 11, 12 of mixing tools sit on an agitator shaft 26 which is passed through the hollow shaft 7 and is connected via a chain drive 27 to a stationary drive motor 28.
  • the agitator shaft 26 is connected in a rotationally fixed manner to the hub 24 of the middle group 11 of mixing tools by means of a feather key 29.
  • Hubs 23 and 25 of the two outer groups 10 and 12 of the mixing tools are freely rotatably arranged on the agitator shaft 26.
  • These two hubs 23, 25 have two annular grooves 30, 31 of limited circumferential length, in each of which a driver pin 32 or 33 engages, which is fixedly connected to the central hub 24.
  • the mixing tools protrude beyond the open edge 2a of the second container part 2. Therefore, in order to be able to detach the first container part 1 from the second container part 2 and remove it in the horizontal direction after the end of a mixing process, it would in principle be necessary to lower the first container part 1 so far that its upper edge 1a lies below the lower edge of all mixing tools. In order to avoid the strong lowering movement required for this and the large overall height of the mixing device required for this purpose, provision is made according to the invention that the mixing tools can be pivoted automatically into the container part 2 when the container parts 1 and 2 are separated.
  • the limited rotational mobility of the hubs 23 and 25 relative to the agitator shaft 26, explained with reference to FIGS. 3 and 4, serves this purpose. It may be assumed, for example, that after the end of a mixing process, the container part 1 in the one shown in FIG the container part 2 is in the lowered position. The mixing tools of the middle group 11 are in this position just above the upper edge 1a of the container part 1. The mixing tools of the two outer groups 10 and 12, however, protrude somewhat into the container part 1. If the container part 1 is now displaced perpendicular to the plane of the drawing in FIG. 1 with respect to the container part 2 by means of the carriage 4, the edge 1a of the container part 1 abuts the mixing tools of the two outer groups 10 and 12.
  • the mixing tools of groups 10 and 12 with their hubs 23, 25 are rotated relative to the agitator shaft 26 against the direction of rotation of the drive, which is made possible by the engagement of the driving pins 32, 33 in the annular grooves 30, 31.
  • the mixing tools of the outer groups 10 and 12 are pivoted so far that the container part 1 is released from the container part 2.
  • Another container part 1 (with a new batch of mixed material) can then be pushed freely under the container part 2.
  • the container part 1 is then raised slightly by means of a lifting device 34 and connected to the container part 2 via tensioning devices (not shown).
  • the motor 9 then swivels the mixing container consisting of the container parts 1 and 2 through 180 ° into the mixing position in which the mixing process is carried out by the agitator driven by the motor 28.
  • the driver pins 32, 33 in the annular grooves 30, 31 of the hubs 23, 25 initially perform an empty movement (over the circumferential length of said ring grooves) 'until they take the hubs 23, 25 and thus the two outer groups 10, 12 of the mixing tools with them.
  • the mixing container is pivoted back into the position shown in FIG. 2, whereupon the removal and removal of the container part 1 proceeds in the manner described.
  • the mixing container consisting of the container parts 1 and 2 has a rectangular cross-sectional shape.
  • the second container part 2 is then also given a circular section (in accordance with FIG. 1) which is not rectangular but circular.
  • the length of the mixing tools is then adjusted accordingly, however, at least in the area of the middle, longest mixing tools, a limited freedom of movement of these mixing tools relative to the agitator shaft is advantageous in order to automatically rotate these long mixing tools when separating the two container parts so that they no longer come in reach into the transportable first container part 1 when it is pulled away in a horizontal direction under the second container part 2.
