Definitions

  • the present invention is related to a mixing device, according to the preamble of claim 1.
  • Mixing devices of this kind are known, for example from No-B-176552 and are used within a number of fields for mixing two or more different substances of particles or liquids or a combination of such, to a desired degree of homogeneousness.
  • the different substances are supplied in amounts which are metered to a specified degree.
  • Such substances may be two or more liquids to be mixed, two or more particles to be mixed or particles to be added and mixed with liquids.
  • the substances to be mixed have greater or smaller differences in nature and condition.
  • Such mixing devices also are used for drying or freezing particles, set out as separate processes or as part of a mixing process.
  • Mixing devices of the above mentioned type normally operate with blades or shovels secured to two parallel rotors, rotating in opposite direction.
  • the shape and the arrangement of the blades causes the masses to be thrown up thereby to be mixed and simultaneously transported forwards in the mixing device. It here certainly is important that the so-called casting curvature is optimized, in order to achieve the best possible mixing simultaneously with the desired forward transportation.
  • figure 1 discloses schematically a mixing device having two rotors, in an axial view
  • figure 2 discloses a side view towards the rotor axis of one blade form
  • figure 3 discloses a corresponding view of a modified blade form.
  • a blade 1 for example as part of a circular pipe
  • such pipe conveniently may be divided into four segments, each corresponding to 90° and where each segment is secured to the rotor as disclosed in figure 2, turned an angle ⁇ in relation to the rotor axis.
  • the angle ⁇ suitably may be 20° which means that part of the masses are influenced by the front part 3 of the blade and one part is influenced of the rear part 4.
  • the curved form of the blade provides a substantial dispersal of the masses being thrown up and partly also a transportation backwards in relation to the transportation direction of the mixing device, namely of the masses which are influenced of the rear part 4.
  • the outer circumference of the blade suitably is bent up to a flange 2 or a flange 2 is secured to the blade, as a continuous curvature or as a obtuse angle to the blade.
  • Figure 3 discloses schematically another embodiment of a curved blade, namely in a cross section not as a part of a circle, but as a curved surface where the rear part 4 still is. maintained to achieve a larger distribution of masses, also stationary and partly backwards in relation to the rotor axis and the transportation direction. As disclosed in the drawing, even here the front part 3 is curved. It is important to maintain a blade with a curvature thereby to achieve a large distribution of the masses and an optimized, high casting curvature 5, as disclosed in figure 1.

Claims (2)

  1. Mischvorrichtung zum Mischen verschiedener Substanzen, wie zum Beispiel Teilchen oder Flüssigkeiten, mit im Betrieb im wesentlichen horizontalen Achsen, an denen Flügel angeordnet sind, wobei jeder Flügel eine Fläche mit einer in Bewegungsrichtung der Substanzen zeigenden Krümmung aufweist und wobei die Form des Flügels in radialer Richtung bezogen auf die Achsen gerade Konturen aufweist, die rechtwinklig zu der Rotorachse angeordnet sind,
    dadurch gekennzeichnet,
    dass der gekrümmte Flügel umfasst: einen ersten Flächenabschnitt (3), der in die Hauptrichtung der Bewegung der Substanzen zeigt, einen zweiten im wesentlichen kleineren Flächenabschnitt (4), der gegen die Hauptrichtung der Bewegung der Substanzen zeigt, und einen Abschnitt, der zwischen den erwähnten Flächenabschitten liegt und diese miteinander verbindet und sich im wesentlichen parallel zu der Rotorachse erstreckt, so dass ein wesentlicher Anteil der Substanzen radial nach außen und vorwärts geschleudert wird, während geringere Anteile radial nach außen beziehungsweise zurück geschleudert werden, wodurch diese Substanzen mit Substanzen vermischt werden, die von dem folgenden Flügel vorwärts geschleudert werden.
  2. Mischvorrichtung nach Anspruch 1,
    dadurch gekennzeichnet,
    dass sich ausgehend von der Achse am äußeren Rand des Flügels ein Flansch (2) befindet, der einen stumpfen Winkel mit dem Rest des Flügels bildet und der in die Hauptrichtung der Bewegung der Substanzen zeigt und sich im Wesentlichen entlang des gesamten äußeren Randes der Flügel erstreckt.
