Definitions

  • the invention relates to a mixing device, in particular for producing a suspension of at least one liquid component and one solid component.
  • a mixing device in particular for producing a suspension of at least one liquid component and one solid component.
  • Such mixing devices are used for example in so-called continuous mixers, which in a continuous operation from the supplied components, the desired mixture, e.g. a concrete mix.
  • a mixing device is used in a so-called mortar mixing pump, which produces immediately usable mortar from the supplied liquid and solid components, which can be injected or sprayed on by means of the mortar mixing pump, for example in tunneling.
  • the described mixing apparatus is also suitable for many other applications in which several solid components are to be mixed with one another or, in particular, liquid and solid components are mixed with one another.
  • a shaft is rotatably arranged which defines an axis of rotation and carries a plurality of mixing blades fixed to the shaft for rotation therewith.
  • mixing devices of this type there is the problem in mixing devices of this type, to achieve the most homogeneous possible mixing within a short time and with low energy consumption.
  • a mixing device in which the material to be mixed by mixing blades should first be pressed apart laterally, then a part of the material to be mixed should be raised and finally the raised part of the mix is to be dropped back into the total mass.
  • the mixing blade heads are formed like a shovel or spoon.
  • the invention seeks to remedy this situation and provides this starting from the above-mentioned prior art, a mixing device ready, in which a plurality of mixing blades are mounted on the shaft for rotation in a preferred direction of rotation. At least two of these mixing blades have a wedge-shaped in cross-section Main body extending radially outward from the shaft.
  • the term "wedge-shaped cross-section” includes all cross-sectional shapes that provide a wedging action regardless of whether the wedge is pointed, rounded or truncated, and regardless of whether the side cheeks forming the wedge are flat, convex or concave.
  • On the free end of the main body of each of these at least two mixing blades is connected to the main body, also wedge-shaped mixing blade head.
  • the mixing blade head can be made in one piece with the associated base body, but it can also be a separate part, which is connected in a suitable manner with the base body.
  • Both the wedge tip of the base body and the wedge tip of the mixing blade head of each trained mixing blade points in the preferred direction of rotation of the shaft, ie when rotating the shaft in the preferred direction of rotation, the wedge tips of the base body and mixing blade head come first with the material to be mixed in contact.
  • Both the base body and the mixing blade head expands, starting from the associated wedge tip, in the axial direction of the shaft, but this extension is more pronounced in the mixing blade head than in the base body, so that as a result a wider mixing blade head is arranged on a narrower base body.
  • the extension can be made only to one side of the wedge or on both sides of the wedge.
  • the main body and / or the mixing blade head can rejuvenate after expansion.
  • a transition region is formed between the narrower base body and the wider mixing blade head on at least one side of the base body, which connects a side surface of the base body with an associated bottom of the mixing blade head and which is inclined relative to the axis of rotation of the shaft so that in preferred direction of rotation rotating shaft contained in the mixing chamber, to be mixed is conveyed inward to the shaft.
  • the transition region may be formed by a curved surface which is inclined in several planes with respect to the axis of rotation of the shaft and whose inclination changes continuously over its course.
  • the mixing blade head expands axially with respect to the main body to both sides. It can then on each side of the main body a transition area between the Be formed body and the mixing blade head. Such an embodiment intensifies the mixing again.
  • the degree of axial expansion of the base body and / or the mixing blade head on the one hand may differ from the extent of the axial extension on the other side, i. the axial extension of the body and / or the mixing blade head need not be mirror images, but may well be asymmetric. It is also possible that e.g. the main body extends axially only on one side, while the mixing blade head expands axially on both sides.
  • the wedge tips of the main body and mixing blade head are aligned with each other, i. they are arranged along a common line.
  • the wedge tip of the mixing blade head may be offset from the wedge tip of the body, for example, the wedge tip of the mixing blade head in the direction of rotation of the wedge tip of the body ahead.
  • the inclination of the wedge tip of the mixing blade head may differ from the inclination of the wedge tip of the base body with respect to the axis of rotation of the shaft.
  • the angle included between a normal to the axis of rotation of the shaft and the wedge tip of the mixing blade head is greater than the corresponding angle of the base body.
  • each mixing blade has an annular base on which the base body is fastened.
  • the annular base is provided with an axial passage recess, so that the entire mixing blade can be pushed onto the shaft.
  • the cross section of the shaft is circular, and the axial through hole of the mixing blade may be circular and, for example, have a slightly smaller diameter than the shaft, so that the mixing blade by a press fit or by friction welding on the shaft can be fastened.
  • the shaft portion on which the mixing blade is to be mounted have a certain profile shape, and then the axial passage recess of the mixing blade has a profile shape complementary to the shaft portion.
  • At least two mixing vanes which are aligned with each other in the axial direction of the shaft are present, i. the two mixing vanes are in the same position with respect to the circumferential direction of the shaft, and the main bodies of both mixing vanes are interconnected by a mixing rod extending parallel to the shaft and radially spaced from the shaft.
  • This mixing rod represents an additional mixing element, which further improves the fast and at the same time intimate mixing.
  • such mixing rods may be present between several pairs of mutually aligned mixing blades. In this case, the radial distance of the individual mixing rods from the shaft can be different, so that different areas of the mixing chamber are exposed to the effect of the mixing rods.
  • a plurality of mixing rods may also be present between a pair of mutually aligned mixing vanes.
  • each end of a mixing rod is removably received in a recess formed in the associated base body.
  • Mixing rods can be easily mounted and dismantled as needed, which can be advantageous not only for different requirements with respect to the material to be mixed, but also in a possible replacement of a worn mixing rod.
  • each mixing blade has a core made of metal, which is coated with a plastic.
  • the plastic can be sprayed or molded on the metal core, in particular cast.
  • Plastic coatings are in particular those plastic materials which have sufficient resistance to abrasive stress and to which the components to be mixed adhere as little as possible.
  • the mixing vanes can also be completely made of plastic and, for example be made in one piece by a casting process.

It is understood that the number of mixing blades 16, their axial distance from each other and their angular arrangement with respect to the axis of rotation A can be chosen differently than shown in order to adapt the mixing device 10 to different needs.
  • a so-called counter-wing 18 is arranged at the in Fig. 1 left end of the shaft 12.
  • This counter-wing 18 generates a pressure in the operation of the mixing device 10 against the in Fig. 1 to the left direction of the main flow, to keep in this way the material to be mixed longer in the formed by the action of the mixing blades 16 intensive mixing zone.

Seen spatially, the juxtaposition of the wedge tips 26 of all cross sections of the base body 24 in the embodiment shown forms a straight line (see Fig.
