Definitions

  • the present invention relates to a mixing device, in particular for a mixing device for mixing solids.
  • Mixers for mixing solids, in particular for producing hydraulically bound substances, such as concrete or mortar, are known in a number of different designs.
  • Homogeneity is an essential prerequisite for the production of specification-compliant products with constant product quality.
  • such mixers generally also employ stripping devices with which the caking or sticking of the material to be mixed on the bottom surface or the sidewalls of the mixer is to be prevented.
  • swirls are used, with which the mixing effect is to be strengthened. These are generally arranged so that they have an effect where the Mischgutströmung has calmed down by the effect of the actual mixing tool again so far that the Mischgutströmung runs substantially parallel, which does not have a good mixing at these points result.
  • mixing or whirling tools which have rectangular or square cross-sections.
  • Such tools have the disadvantage that they produce a flow shadow.
  • the material on the surfaces and edges of the tools, in particular also on the fastening elements, via which the actual mixing or whirling tools are connected to corresponding drive shafts, it is possible for the material to be caked or bonded from the mix. If such material at a later time dissolves again and falls back into the material to be mixed, this can lead to inhomogeneities in the composition of the final product and thus to specification not compliant products.
  • This problem is particularly serious when, in the meantime, a product change has taken place, i. in the mixer another product, for example, to be produced with a different color. Solvents from a previous product batch lead to color changes in the product that are not accepted by the customer. The human eye is very sensitive to even minor color changes.
  • EP 0945170 A1 is a mixer with a mixing rotor known, which is rotatable about a substantially vertical axis of rotation by means of a drive motor and whose mixing tools protrude into a mixing trough.
  • Two mixing tools can be controlled by means of a gearbox with a common motor. Both mixing tools have a speed difference predetermined via the transmission. This is disadvantageous because no separate adjustment of the rotational speed of the two mixing tools is possible.
  • WO 2009/071322 discloses a mixer, which also has two from above into the mixing trough mixing tools, wherein by means of two motors, the speed of the two mixing tools is freely adjustable.
  • the mixing tools are not only rotatable about its own vertical axis, but these are also arranged eccentrically on another rotatable element, so that the mixing tools can rotate about the central axis of the rotatable element.
  • the mixing tools and the rotatable element are driven by a gearbox by a common motor.
  • the object of the present invention was therefore to overcome the disadvantages of the prior art, and in particular to provide a mixing device which has the greatest possible flexibility in the control of the individual rotatable elements.
  • mixing apparatus for mixing solids, with a mixing trough and with a first mixing tool rotatable about a substantially vertical first axis of rotation by means of a first motor, a second mixing tool rotatable about a substantially vertical second axis of rotation by means of a second motor and an upper mixing tool Drive element comprising a rotatable by a third motor about a substantially vertical third axis of rotation connecting element, wherein the first mixing tool by means of a first shaft and the second mixing tool by means of a second shaft is directly or indirectly connected to the rotatable connecting element, so that the first and the second Blending tool are introduced from above into the mixing device and the first mixing tool is rotatable about the first and the third vertical axis and the second mixing tool about the second and the third vertical axis, wherein the first vertical axis at a first distance vo n is arranged on the third vertical axis and the second vertical axis is arranged at a second distance from the third vertical axis, wherein
  • a mixing device has an upper end and a bottom end opposite the upper end, the mixer bottom, on, and side ends.
  • the upper drive element is obviously arranged on or in the region of the upper end of the mixing device, so that the mixing tools are inserted from above into the mixing trough and project into this.
  • substantially "vertical” is to be understood as meaning that deviations of the angle of the vertical axes and of the mixer bottom from 90 ° (as obtained with an exact right-angled arrangement) are possible to a small extent (usually less than 10 °, preferably less than 5 °).
  • the vertical axes are exactly at right angles to the mixer bottom.
  • the third vertical axis can form a central axis of rotation about which the first and the second axis of rotation again rotate. It has proven to be advantageous if the first and second axes of rotation are arranged symmetrically spaced at different distances from the third axis of rotation opposite. However, this is not mandatory. As it were applications are conceivable in which an asymmetrical arrangement of non-opposing first and second axes of rotation can provide advantages.
  • the inventive assignment of a respective motor to each rotatable element is made possible that the rotatable connection element, also referred to as a platform, is completely decoupled from the rotation of the mixing tools.
  • the individual mixing tools can each be controlled independently of each other.
  • This construction according to the invention of a mixing device makes it possible to adapt to different mixes without having to make any modifications to the mixing device itself.
  • the first and second motors are suitably connected in a force-transmitting manner, directly or indirectly, to the mixing tool, whereby the mixing tools are moved through the mix.
  • the structural design of the connection of the first and second shaft and the first and second motor can be done in a conventional manner and those skilled in the relevant possibilities are known here. A detailed description in this context is therefore dispensable at this point.
  • energy-saving modes can also be realized so that, for example, only one of the mixing tools is used with small filling quantities.
  • the rotational speed of the first, second and third motor is independently adjustable.
  • the rotational speed of the first and second mixing tools as well as of the rotatable element, ie the platform can be freely selected between fast turning and mixing up to a complete standstill for saving energy. This allows a large variability of the mobile mixing programs.
  • the first and the second mixing tool is identical, in particular in the form of identical mixing blade are formed.
  • first and the second mixing tools may be designed in the form of different mixing tools.
  • the first mixing tool is arranged at a third distance from the rotatable connection element and the second mixing tool is arranged at a fourth distance from the rotatable connection element, wherein the third distance and the fourth distance are different.
  • the difference of the third and fourth distance is greater than or equal to the height of the further spaced from the rotatable connecting element mixing tool.
  • the mixing tools must not be arranged in one plane. If these are arranged in one plane, it may be necessary in particular for mixing blades that they be operated in a synchronized manner, since they intermesh.
  • the mixing tools are arranged offset in height relative to one another, in particular offset at least in such a way that the difference of the third to the fourth distance is at least equal to the height of one of the Mixing tools, so they can be controlled completely independently.
  • the first, the second and / or the motor is arranged outside of the mixing trough, in particular on the upper side of the upper drive element.
  • the upper drive element gears and / or transmission elements comprises, by means of which in each case the operational coupling between the first motor and the first mixing tool, the second motor and the second mixing tool and the third motor and the rotatable connecting element takes place.
  • each of the three motors is preceded by a control or regulation unit by means of which the speed and / or direction of rotation of the motors can each be predetermined independently of one another.
  • the rotatable connecting element is formed at least substantially rotationally symmetrical with respect to the third vertical axis.
  • the rotatable connection element or the platform is preferably at least approximately circular or oval. Such a configuration has proved to be particularly advantageous.
  • the first and / or the second mixing tool is designed in the form of a mixing turbine, a mixing arm, a mixing blade and / or a mixing star.
  • first and / or the second mixing blade may have a bend at the outer section relative to the first or second vertical axis and convex or concave towards the outside rising is executed.
  • At least one mixing blade of the tool according to the invention has a bend on the outer section relative to the central shaft. This bend is round, preferably designed approximately circular. This configuration of the mixing blade ensures that the mix collected from the center of the mixer and can be distributed with momentum in the region of the outermost, reachable by the inventive tool radius of the mixing device over the entire mixer surface.
  • a mixing tool according to the invention with mixing blades thus has a central shaft with a strut arranged essentially at right angles, on which the mixing blade or the mixing blades are arranged.
  • the corresponding adaptation to the bottom of the mixing device is achieved in part by replacement of the mixing blades or by elaborately sealed designs in which the height adjustment by moving parts, which are in the range of the mix.
  • the tool according to the invention is structurally much simpler and easier to maintain, in particular by means of the flange suspension described above, since it has neither moving parts in the mixed material nor fastening or adjusting devices are required that could come into contact with the mix and can be prone to contamination. Dirt leads to malfunctions, which in turn result in downtime, which is undesirable for economic reasons.
  • a strut is advantageously arranged substantially at right angles thereto, which is correspondingly horizontal and quasi parallel to the bottom of the mixing device with vertical installation of the shaft in the mixing device.
  • a strut is advantageously arranged substantially at right angles thereto, which is correspondingly horizontal and quasi parallel to the bottom of the mixing device with vertical installation of the shaft in the mixing device.
  • deviations of the angle of the main axes of the shaft and strut of 90 ° are possible to a small extent (usually less than 10 °, preferably less than 5 °), as far as the geometric design of the mixer bottom allows.
  • the longitudinal axis of the strut is exactly at right angles to the longitudinal axis of the central shaft.
  • the desired good mixing usually requires an arrangement of at least one of the mixing blades immediately above the bottom of the mixer, which requires a parallelism of the strut to the mixer bottom when the strut has a mixing blade at both ends or forms a mixing blade.
  • This in turn requires a perpendicularity of the longitudinal axis of the strut to the longitudinal axis of the central shaft, if it is to be installed in the simple manner described above.
  • the first and / or the second mixing blade in the region which comes into contact with the mix has no fastening or adjusting devices.
  • each having a mixing blade at each end of the strut the bend is advantageously designed so that the bending direction of the two mixing blades is in the opposite direction relative to the main vertical plane of the strut.
  • the mixing blade is designed "outward" towards the outside, i. the vertical height of the mixing blade at the outer end remote from the shaft is greater than at the part of the strut closest to the shaft at which the design of the mixing blade begins.
  • the pitch can basically be designed arbitrarily, but it is preferred if this is done without the formation of edges or comparable transitions, as these in turn could negatively affect the mixing effect.

  • the strut is designed so that in an inner region between the mixing blade and central shaft at the bottom, the bottom of the mixing device associated side of the strut creates a passage through which the mix can dwell in the mixing process in the center of the tool or can flow slowly under the strut through.
  • the self-cleaning performance of the tool according to the invention can be improved. This is achieved most easily by the fact that at least one inner region of the strut at its bottom facing the mixing bottom compared to the area which is formed by the mixing blade (s), a greater distance from the mixer bottom than the mixing blade (s). Constructively, this can be achieved simply by a corresponding design of the strut with a vertical recess, preferably this return is bent again without forming edges, preferably circular in shape.
  • first shaft and the first mixing blade and / or the second shaft and the second mixing blade are designed in one piece.
  • the central shaft and the strut arranged thereon are particularly advantageously designed in one piece, ie are produced from a one-piece blank by appropriate design (eg by machining or the like).
  • This construction eliminates fastening devices for fastening the strut to the central shaft, which could reach the flow area of the mixed material during operation and may accordingly be prone to contamination. In such places, the unwanted caking and deposits mentioned in the introduction are particularly easy to form.
  • first mixing blades and / or two second mixing blades are arranged mirror-symmetrically to each other on the first and second vertical axis.
  • At least one of the shaft remove end of the strut at least one mixing blade is arranged or the strut itself forms such a mixing blade.
  • a mixing blade or is formed there is arranged at each end of the strut.
  • Arranged means in the context of the present invention preferably that the mixing blade is designed without located in the region of the mix fasteners. In principle, this can be achieved by attaching a mixing blade to the strut with the corresponding geometric by gluing or welding. In contrast to screwing or the like arise during bonding or welding no lying in the range of the mixed material attack points by fastening devices that tend to caking or sticking of the mix.
