Definitions

  • the invention relates to an industrial mixing machine, comprising a mixing head and at least one connection means for connecting a mixing container, which contains a mixed material and is open on the connection side, to the mixing head for the purpose of forming a closed mixing container, which mixing head, as part of a pivotable assembly, is pivotably mounted relative to a frame in such a way that so that the closed mixing container formed from the mixing head and mixing container can be swiveled relative to the frame for carrying out the mixing process, and which mixing head has at least one mixing tool with several radial blades that is rotatably driven and seated on a drive shaft that extends through the base of the mixing head, which radial blades have a cross-sectional geometry , according to which, starting from its maximum thickness, the wing thickness decreases in the direction of rotation towards the rear wing end.
  • mixing tools are used, which are used in particular for mixing bulk material, typically powdery bulk material, such as this, for example, for preparing plastic granulate mixtures or also in the paint industry.
  • Mixing machines for this purpose have a mixing head which can be swiveled with respect to a frame and which simultaneously serves to close a mixing container containing the material to be mixed, which is connected to the mixing head for the purpose of mixing a material to be mixed therein. After connecting the container to the mixing head, a closed mixing container is formed from the mixing head and the mixing container containing the mixed material.
  • the mixing head has connection means.
  • connection flange which protrudes outward in the radial direction and against which the complementary connection flange of the mixing container is brought into contact.
  • spindle strokes are used, for example, with which the mixing container with its connection flange is pressed against the connection flange of the mixing head with the interposition of a seal.
  • the mixing head itself has a concavely curved bottom side which merges into a circumferential cylindrical wall which runs concentrically to the central axis of the mixing head and which carries the connection flange at its free end.
  • the mixing head carries at least one mixing tool, the drive shaft of which is passed through the base of the mixing head.
  • the mixing head itself is arranged pivotably with respect to the machine frame of the mixing machine so that the mixing with respect to the mixing head is in an overhead position in which the mixing head is at the bottom and the mixing container connected to it is at the top. This overhead position is necessary so that the mix contained in the mixing container comes into contact with the at least one mixing tool carried by the mixing head.
  • the rotationally driven mixing tool is used to generate a flow of mix within the closed mixing space.
  • Such an industrial mixer is off, for example EP 0 225 495 A2 known.
  • a mixing tool as described above is off DE 20 2016 107 397 U1 known.
  • the radial wings of the mixing tool known from this document have a cross-sectional geometry which corresponds to the cross-sectional geometry of the wing of an aircraft.
  • the cross-sectional geometry of the radial wings is shaped like an airfoil and has a convex upper side with a curvature that essentially decreases towards the rear in the direction of rotation and an underside that continuously merges from a convexly curved, front section in the direction of rotation into a concavely curved rear section.
  • the front side pointing in the direction of rotation is convexly curved.
  • the radial vanes can carry outer vanes which have a wedge-shaped cross-sectional geometry, the thickness of the outer vanes decreasing counter to the direction of rotation.
  • the wing-shaped The cross-sectional geometry of the radial blades should be responsible for good mixing at a relatively low running speed. Due to the special cross-sectional geometry of the radial blades, the production thereof is relatively complex, which increases the cost of such a blade mixing tool.
  • the invention is based on the object of developing a mixing machine with a mixing tool which has several radial blades of the type described above in such a way that good mixing is not only given when the service life is low, and floor or wall caking in the mixing head or are reduced on the walls of the mixing container, but the mixing tool can also be produced more cost-effectively.
  • the radial wings of the mixing tool are more strongly employed with their wing underside in relation to a horizontal than the wing tops, namely in the section of decreasing wing thickness.
  • the horizontal in the context of these explanations is a straight line in that plane which runs at right angles to the axis of rotation of the mixing tool.
  • the underside of the wing is inclined in the direction of rotation. This means that an imaginary extension the underside of the wing runs towards the bottom of the mixing container in the direction of rotation.
  • the radial blades are designed over their entire extent in the direction of rotation (their cross-sectional width) in such a way that an imaginary straight line connecting the rear end to the respective front end is inclined in the same direction as the slope of the underside of the wing in the section of decreasing thickness.
  • the front end of such a radial wing when projected into a common vertical plane with the rear wing end, is at a lower level than the rear radial wing end.
  • the radial wings taper towards the rear wing end.
  • the maximum thickness in the radial wing cross section is preferably at a distance from the front end of the radial wing pointing in the direction of rotation.
  • the upper side of the wing of the radial wing is inclined in the same direction as the lower side of the wing.
  • the upper side of the wing as a whole and thus also its section between the maximum wing thickness and the rear wing end is used to give the mixed material particles contacting the upper side of the wing an upward moment due to the rotation of the radial wings.
  • Such a cross-sectional geometry can be formed with straight wing surfaces, the adjoining edges of which can definitely be rounded. If such an additional upward moment acting on the material to be mixed is not to be introduced, the radial blades can also be designed with a horizontal upper side of the blade, starting from their maximum thickness towards the rear wing end.
  • a particularly simple radial wing cross-sectional geometry has a radial wing which, with regard to its cross section, is mirror-symmetrical to the plane in which the straight line connecting the rear end with the front end lies.
  • the special spatial position of the radial blades with their inclination ensures, even with such a geometrically simple cross-sectional design, that an upwardly directed moment is exerted on the underside of the blade, which acts on the mix particles.
  • the wing undersides of the radial wings are straight from their maximum thickness towards the rear wing end.
  • the entire underside of the wing is virtually straight, that is, from the front to the rear wing end.
  • the upper side of the wing can also be made straight, at least in the section of decreasing thickness. Only the area of maximum thickness will typically be rounded, as will the front side of the wing pointing in the direction of rotation.
  • the inclination of the imaginary straight line between the rear and front wing ends is inclined at the maximum with that angle to the horizontal at which the underside of the wing is inclined with respect to the horizontal in the section towards the rear wing end of decreasing thickness.
  • the underside of the wing does not have any depressions, such as concave-shaped sections, which simplifies its producibility.
  • the front of the radial wings can be rounded, for example with a curve with a constant radius. It goes without saying that the radius cannot be constant either. Then, as a rule, the radius between the end of such a radial wing pointing in the direction of rotation to the wing top side will be designed with a larger radius than that part of the rounding that has the front Completion of the radial wing connects to the underside of the wing. It is also entirely possible to design the front end of such a radial wing as an edge, preferably rounded, by bringing the upper side of the wing together with the lower side of the wing.
  • the radial wings each have an outer wing at their end.
  • This preferably has the same cross-sectional geometry as the radial vanes.
  • the outer wings are arranged with regard to their cross-sectional geometry that that wing side which is the underside in radial flights is the wing side pointing outward in the radial direction in the case of the outer wings.
  • the outer wing sides of the outer wing are preferably positioned with respect to a cylindrical jacket surface enveloping the outer wing sides in the same way as the underside of the wing with respect to a horizontal line.
  • the angle of incidence of the outer sides of the wing with respect to the enveloping cylindrical lateral surface can be the same as the angle of incidence of the undersides of the wing with respect to a horizontal.
  • the angle of incidence of the outer sides of the wing with respect to the enveloping cylindrical lateral surface can, however, also differ from the angle of inclination of the underside of the wing with respect to a horizontal, for example be a few degrees smaller.

  • the lifting device 10 has a lifting plate 11 as part of a lifting plate unit which can be moved in the vertical direction by a spindle 12. There is another plate on the lifting plate, which has a bevel towards the container flange. This will center the container when it is lifted.
