Definitions

  • the invention relates to a mixing device for mixing a base material with a liquid, with a vertical feed chute for the base material and a mixing chamber arranged below the feed chute, in which the liquid is supplied and a mixing tool is driven in rotation, wherein in the feed chute a about a vertical axis rotating propeller is provided in which are provided in the radial direction extending wing elements, according to the preamble of claim 1.
  • liquid from the mixing chamber can spray into the feed chute and there with the base material to bonds or clumping and thus can lead to clogging of the feed chute.
  • a propeller conveying into the mixing chamber is provided at the lower end of the feed chute.
  • the propeller rotating in the feed chute about a vertical axis is designed such that it either forms a continuous screw conveyor or is composed of individual screw flights, which sit one above the other in the axial direction and in Circumferential direction are offset from each other, so that between them only axial spaces are free. In the axial direction, however, this propeller composed of individual worm gear pieces is also closed, since the individual worm gear pieces overlap each other and overlap.
  • the object of the present invention is therefore to develop a mixing device as indicated above in such a way that such a clogging no longer occurs.
  • such an embodiment also has the further advantage that the base material is still homogenized by the propeller, which leads to better mixing results in the subsequent mixing with liquid.
  • Such a closing of the feed chute against high-spraying liquid from the mixing chamber can be achieved in particular if several (in particular four) vanes are provided on the propeller in a plane which is arranged normal to the central axis of the propeller. If necessary, the propeller can also have several corresponding planes with wings interconnected. This not only increases the "tightness" down but also improves a homogenization of the base material when it is fed to the mixing bracket.
  • the feed chute should preferably closely surround the propeller, for example, with a gap width between the rotating blade ends and the wall of the feed chute of less than 5 mm, preferably 0.5 ⁇ 3 mm.
  • the mixing tool rotates about a vertical axis.
  • the mixing tool arranged below the feed chute in the mixing space is rotatable about a vertical axis. It is advantageous if the supply shaft is rotationally symmetrical and its central axis is aligned with the axis of the mixing tool.
  • the propeller can then be mounted directly on the upper end of the mixing tool.
  • the blades of the propeller are set in the conveying direction to ensure the supply of raw material into the mixing chamber.
  • the feed chute itself can not only be cylindrical as a whole.
  • the feed chute can also be formed conically narrowing. As a result, for example, fluidizing powder is compressed, whereby agglomerates are better digested.
  • the base material is rather sticky, but it has also proved to be advantageous to form the feed slot conically widening. As a result, such sticky raw materials are loosened.
  • FIG. 1 shows the side view of a mixing device.
  • a shaft bearing 2a is mounted with electric motor 2b, which is connected via a belt drive 3 with the input shaft 4.
  • a mixing drum 6 is flanged, in the inner mixing chamber 7, a mixing tool 8 is driven in rotation.
  • the central axis 9 of the mixing tool is aligned in the vertical direction.
  • a vertical feed chute 11 is screwed onto this via a flange 10. This feed chute 11 has a smaller diameter than the mixing chamber 7 arranged below the feed chute.
  • a propeller 15 Within the feed chute 11 rotates a propeller 15, in which a plurality of wings 17 are distributed over a shaft 16, as can be seen in FIG. 2 in the plan view. In the radial direction, the wings 17 protrude close to the inner wall of the feed chute 11, which thus surrounds the propeller to form a narrow gap. These wings 17 leave within the Zu manufacturedschachtes 11 a plurality of segments 18, which are axially parallel throughout. When the propeller 15 is stationary, 18 raw materials could fall directly into the mixing chamber 7 through these segments.
  • the propeller 15 rotates at a speed of more than 200 revolutions per minute (see arrow 19). Characterized homogenized by the wings 17 in the segments 18 base material already within the feed chute 11 before it is then added in the mixing chamber 7, the liquid which is mixed by the mixing tool 8 with the base material.
  • the finished mixture is discharged through a discharge pipe 20 from the mixing device.
  • the mixing chamber 7 can be kept at the appropriate temperature via cooling water connections 21.
  • the vanes 17 are each arranged in one plane.
  • two planes, each with four wings 17 arranged therein, are arranged one above the other, wherein the corresponding wings 17 lie exactly one above the other and, as can be seen, are easily adjusted.
  • propeller is mounted directly on the mixing tool 8 and thus only one common drive must be provided for mixing tool 8 and propeller 15.
  • the feed chute may also have a conically narrowing shape, as indicated by reference numeral 22 in FIG.
  • a base material such as fluidizing powder
  • it is compacted, which results in agglomerates being better digested in the feed chute 22.
  • the invention thus represents a possibility to build a mixing device with a vertical orientation, in which a blockage of the feed chute is reliably avoided and also provides very good mixing results due to a pre-homogenized base material.
