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 coutinous 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.
  • Fig 1 shows a vertical view of a device according to the invention, where the oscillation is obtained by help of an asymmetric arrangement of the mixer, while Figs 2 and 3 show a horizontal and a vertical view of a mixer provided with rudders.
  • FIG. 1 stands for a mixer with a propeller 2 and a rack 3.
  • 4 stands for a guide and 5 sliding means.
  • 6 stands for a connection arm, 7, 8, 9 and 10 stopping means, 11 actuating means, 12 rudders, 13 spring means and 14 and 15 actuating means.
  • F stands for the reaction force.
  • the mixer 1 is arranged on and may be slidable along a vertical guide 4, the arm 6 attaching the mixer to the guide being inclined with regard to the longitudinal axis of the mixer. This causes the reaction force F from the propeller 2, to be directed at the side of the guide 4.
  • the arm 6, is pivotedly attached to the mixer which means that the latter will turn around that joint during operation.
  • the arm 6 may also within limits be pivoted around the guide 4 or, as in the drawing , the whole guide 4 may be turnable.
  • the mixer will then oscillate automatically between two decided positions without any need for external energy. In this way may, as mentioned above, a more efficient mixing be obtained with an unchanged energy consumption.
  • 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 propeller 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 continous 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 change-over 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.
