Definitions

  • This invention concerns a device for a mixer for mixing liquids, which device automatically changes the direction of the mixer to increase the liquid volume operated by the mixer making the mixing more effective.
  • Such mixers are used for mixing liquids and suspensions of different kinds and may be placed in tanks in water courses etc.
  • a submersible mixer comprises a driving unit such as an electric motor and a propeller built together into a unit which is normally arranged to be lowered into the liquid along a vertical guide.
  • a driving unit such as an electric motor and a propeller built together into a unit which is normally arranged to be lowered into the liquid along a vertical guide.
  • the guiding or controlling is carried out manually, but an automatic adjustment by help of an external driving source could occur.
  • a manual guiding can of course not be continuous and a separate driving source means a considerable additional cost, especially at outdoor installations such as purification plants and means for preventing formation of ice.
  • This known device has however the disadvantage, that the movement of the mixer will be very unstable and thus it is very difficult to obtain a correct mixing of the entire tank.
  • reaction force from the mixer propeller is used to obtain a controlled turning of the mixer between two extreme positions.
  • FIG. 1 stands for a mixer with a propeller 2 and a rack 3.
  • 4 stands for a guide and 5 sliding means, 7 and 8 stopping means, 12 rudders, 13 spring means and 14 and 15 actuating means.
  • the mixer 1 is pivotedly attached to the vertical guide 4.
  • the mixer is provided with one or several rudders 12, placed in the current created by the mixer.
  • the rudder or rudders are provided with springs 13, which direct them in two alternative inclinations. The function is described below.
  • the reaction force F from the current will act on the rudder and turn the mixer to bring the jet away from the rudder surface.
  • the rudder which is mounted on the mixer, accompanies said turning movement and after a certain angle it contacts a fixed stopping means 8.
  • the mixer continues its turning movement further until the rudder 12, influenced by the stopping means 8, changes its angle with regard to the current direction. At first it takes a position in parallel with the current and then a certain angle in the opposite direction. The changeover is facilitated by a spring 13, which is stretched when the rudder takes its middle position in parallel with the current.
  • rudders In order to secure the function and diminish the risk for disturbance in the current, there are preferably two rudders provided, one at each side of the propeller circumference. The two rudders will then alternatively be present within the current. They are, however, linked to each other such that they always turn in uniform.
  • a dampening means is arranged which prevents the mixer from jittering without control. This can be obtained by help of hydraulic dampeners having link arms.

Claims (4)

  1. Tauchmischer für Flüssigkeiten und mit automatischem Richtungswechsel, mit einer im wesentlichen vertikal ausgerichteten Führung (4), deren unteres Ende am Boden eines die Flüssigkeit enthaltenden Behälters angebracht ist, und mit einem an der Führung (4) gleitend verschiebbar angeordneten Mischer (1), der unter dem Einfluß der Reaktionskraft (F) seines eigenen Strahls während seines Betriebs seine Richtung horizontal und/oder vertikal automatisch ändert, ohne daß dabei in irgendeiner Weise externe Energie zugeführt wird, wobei die horizontale Bewegung des Mischers durch eine Anschlageinrichtung (7, 8) begrenzt wird,
    dadurch gekennzeichnet, daß der Mischer (1) mit wenigstens einem Ruder (12) versehen ist, das in dem von dem Propeller (2) erzeugten Strom angeordnet ist, wobei das oder die Ruder (12) um eine parallel zu der Führung (4), um die der Mischer (1) schwenkbar ist, verlaufende Achse bzw. Achsen schwenkbar ist bzw. sind und dazu ausgelegt ist bzw. sind, eine automatische Schwenkbewegung zwischen zwei Neigungsstellungen in bezug auf die Abströmrichtung von dem Mischer auzuführen, wobei die Schwenkbewegung unter Steuerung der Anschlageinrichtung (7 und 8) erfolgt.
  2. Tauchmischer nach Anspruch 1,
    dadurch gekennzeichnet, daß der Mischer (1) mit zwei parallelen Rudern (12) versehen ist, die abwechselnd in dem Abstrom von dem Propeller (2) vorhanden sind.
  3. Tauchmischer nach Anspruch 1,
    dadurch gekennzeichnet, daß das oder die Rinder (12) mit einer Federeinrichtung (13) versehen ist bzw. sind, die derart auf das bzw. die Rinder wirkt, daß dieses bzw. diese zwei alternative Neigungsstellungen in bezug auf den Abstrom von dem Propeller (2) einnimmt bzw. einnehmen.
  4. Tauchmischer nach Anspruch 1,
    dadurch gekennzeichnet, daß eine Dämpfungseinrichtung vorhanden ist, die die Geschwindigkeit der Schwenkbewegung und/oder die Häufigkeit begrenzt.
