Definitions

  • the present invention relates to a mixing device, in particular a hygiene Mischvorrich device for the production of food products and pharmaceuticals.
  • the mixing device has a mixing container for receiving mixed material and a mixer lid, which can close a mixer opening of the mixing container, wherein the mixing container in the closed Po position is rotatably mounted relative to the mixer cover.
  • mixing devices have a rotatable mixing tool inside the mixing container.
  • a mixing device generally to mix the mix in a container Mischbe best possible. Often, however, there are certain locations within the mixing vessel to which mix accumulates during mixing and possibly fixed. Such, usually not directly overflow of mixed material bodies are often located on edge surfaces, seals and in particular on the relative to the mixing vessel stationary mixer cover. Consequently, the mix accumulated at these locations no longer participates in the mixing process.
  • the mixing container rotates in operation about an axis of rotation.
  • the treatment carried out in the mixing process such as. Dry mixing
  • granulating or suspending different angles of inclination of the rotating mixing container can allow a particularly efficient treatment.
  • the angle is ver, which encloses the axis of rotation of the rotating mixing vessel with the vertical.
  • an inclination angle of about 20 ° to 30 ° is used. Due to the inclination of the mixing container, the mix is exposed to an additional downgrade force, resulting in an additional rolling movement of the mix, which produces particularly sphäri cal granules.
  • a horizontal or only a few degrees ( ⁇ 5 °) inclined orientation of the mixing container is necessary to avoid accumulation of liquid at the lowest point of the mixing container. For example, in the case of dry mixtures, inclinations of about 10 ° to 15 ° have proven to be particularly advantageous in order to achieve efficient and complete mixing as well as particularly rapid and complete emptying.
  • a mixing tool is usually additionally arranged within the mixing container, which does not rotate with the mixing container.
  • the mixing tool rotates preferably about its own axis of rotation, which is usually arranged in egg nem certain distance from the axis of rotation of the mixing container parallel to this.
  • Such a mixing tool is often designed as a mixing shaft.
  • the mixing container In areas with high hygiene requirements, such as in the production of food and pharmaceuticals, the mixing container must also be completely and tightly closable. Therefore, mixing apparatus on such application fields usually have a mixer cover
  • Known mixing devices usually have a fixed predetermined angle of inclination, which can be varied if at all very cumbersome and structural changes of the device. This has the consequence that the angle of inclination of the mixing container after initial installation of the mixing device is usually unchangeable and above all can not be changed during operation or for cleaning purposes.
  • the object of the present invention is therefore to provide a mixing device whose angle of inclination is particularly easy to set by the user and which can be particularly easily cleaned and inspected by the user.
  • the mixing device has a mixing container rotatable about a first axis of rotation for receiving mixed material.
  • This mixing container has a mixing aperture, wherein a mixer lid is provided which can be reciprocated between an open position and a closed position. In the closed position, the mixer lid closes the mixer opening and in the open position, the mixer lid releases the mixer opening.
  • the mixing device has a machine stand, in which the mixing container is mounted rotatably or pivotally. The mixer lid is attached to the machine stand in such a way that it does not have to co-rotate with the mixing container during rotation of the mixing container during operation in the closed position.
  • the machine stand has a stationary element and a pivoting element.
  • the pivot member is pivotally mounted about a pivot axis relative to the stationary member and the mixing container is rotatably mounted on the pivot member, wherein the mixer cover is attached to the pivot member.
  • Between mixer cover and mixing container is - preferably arranged in a closed position of the mixer cover - a sliding seal so that the mixer cover despite the relative rotational movement of the mixing container can seal it tight.
  • the user can set a desired inclination angle by pivoting the pivoting element about the pivot axis.
  • the user can increase the accessibility to normally inaccessible or hard to reach areas of the mixing device by pivoting about the pivot axis, which simplifies the cleaning and inspection of the mixing device.
  • the pivot axis passes through the mixing container.
  • a mixing vessel is usually a vessel with a cylindrical outer wall, a substantially circular vessel bottom and a vessel bottom opposite the circular mixing container opening.
  • the pivot axis preferably extends through the third of the mixing container, which - in relation to the expansion of the mixing container along the axis of rotation - the mixer opening is closest.
  • the pivoting element with respect to the pivot axis at least by up to 90 °, preferably at least up to 180 ° and especially before given to pivot by up to 360 °.
  • the pivoting range of 90 ° makes it possible, on the one hand to adjust the gän for the mixing operation angle of inclination and on the other to pivot the mixing container so that a cleaning and inspection of the container interior is simplified.
  • the mixing container from a vertical position to a horizontal position - say 90 ° - can be pivoted, the cleaning and inspection of the interior in the horizontal Stel development is particularly simple.
  • With a pivoting range of up to 180 ° on the one hand, the accessibility of the pivoting element increases.
  • the mixing container is pivotable from a substantially vertical position to an opposite vertical position, the mixer opening for emptying the mixing container using gravity may be used.
  • a swivel range of 360 ° offers all of the aforementioned advantages and allows regardless of the location and positioning of the mixing device a comprehensive accessibility of the pivoting element and thus all components of the mixing device, which is extremely advantageous for example in cleaning and maintenance.
  • the first axis of rotation and the pivot axis are arranged perpendicular to each other, wherein they preferably intersect at a point.
  • This measure also leads to a compact design and to a reduction of the necessary pivoting space.
  • the mixer opening is circular and the mixing container is rotationally symmetrical with respect to the first axis of rotation and preferably At least partially cylindrical and / or cone-shaped.
  • Preferred embodiments have in particular cylindrical mixing container with a flat bottom or conical, cylindrical or cylindrical-conical mixing container with flat or convex or concave shaped floors, eg dished ends.
  • the circular design of the mixer opening also facilitates the storage and sealing of the mixer lid relative to the mixing container, because it does not rotate in a closed position of the mixer lid during operation with the mixing container.
  • the mixing container has a flange.
  • This flange has a surface facing the mixer opening and a surface facing away from the mixer opening and is generally located on the outer wall of the mixing container.
  • the flange encloses the outer wall of the mixing container completely.
  • a rotary bearing is provided which preferably connects the surface of the flange, which faces in a direction facing away from the mixer opening, with the pivoting element.
  • the pivot bearing can be formed for example as a ball bearing.
  • this bearing can in principle be attached to any position of the mixing container with respect to the axis of rotation.
  • a flange has been found to be particularly advantageous, which is mounted with respect to the axis of rotation in the third of the mixing container, which is closest to the mixer opening.
  • the pivot bearing via a flange also has the advantage that a pivot bearing on the mixing container bottom, as it is often found in other mixing devices eliminated.
  • the mixing container bottom is thus basically freely accessible from below and can be provided, for example, with a double jacket for mixing container or Mischgutkühlung with concentric liquid supply and removal over the first axis of rotation or with an emptying opening.
  • the emptying opening is preferably smaller than the mixing opening.
  • the pivot bearing may also be attached to the other surfaces of a flange, in particular also on the surface facing the mixing container opening. This can be advantageous, for example, if an attachment to the surface facing away from the mixer opening is not possible due to design-related lack of space.
  • the rotary bearing is surrounded by a lubricant-tight housing (oil-tight or lubricant-tight housing).
  • the housing may have seals at the interfaces to the pivot element or to the mixing container, which seal the pivot bearing relative to the exterior space.
  • the housing can also be formed, for example, by corresponding designs of the flange and the pivoting element as well as by arranged between the individual elements seals.
  • the mixer cover has a mixing element (mixing tool) mounted rotatably relative to the mixer cover with respect to a second rotation axis, preferably a mixer shaft.
  • This mixing element is designed and arranged on the mixer cover, that it is located in a closed position of the mixer lid within the mixing container, wherein the second axis of rotation is preferably parallel and particularly preferably parallel but not identical to the first axis of rotation.
  • the rotational speed of the mixing element can be selected independently of the rotational speed of the mixing container.
  • a wiper element or a wiper device may additionally be arranged on the mixer cover in such a way that it is located within the mixing container when the mixer cover is in a closed position.

  • the stripping element is movable relative to the mixing container, wherein preferably the stripping element is rigidly connected to the non-co-rotating mixer cover and the mixing container moves in operation by the rotation of the mixing container relative to the stripping.
  • a mixing and / or stripping element of the type described By a mixing and / or stripping element of the type described a stronger mixing of the mix is effected. Since the mixing and stripping element is attached to the mixer lid, it does not rotate with the mixing container even during operation. The mixing material in the mixing container is therefore caused by the rotation of the mixing container in a relative movement to the mixing and stripping offset. This alone already causes a thorough mixing. If the mixing element is now set in rotation relative to the second rotation axis, then a second superimposed mixing movement is added, as a result of which the efficiency of the mixing device is significantly improved.
  • the mixing and stripping element Due to the attachment of the mixing and stripping element on the mixer cover, the mixing and stripping element is accordingly given away during a pivoting movement.
  • the lamellae described above cover parts of the inside of the mixing container and thereby additionally ensure that no residues of the mix material form on the inside of the mixing container.
