Definitions

  • the invention relates to a device for mixing at least one flow medium, wherein at least two partial flows of the flow medium are brought together to produce a turbulent flow.
  • Turbulence in flow media that is as strong as possible can be exploited in numerous chemical and physical processes. It is known that the greater a - fluctuating movement to the main flow direction, the more turbulent is a flow. It is known to direct a control flow transversely to a main flow in order to achieve a change from laminar flow to turbulent flow at the impact heads. At this envelope, the pressure drops sharply and the flow media "jump" in the transverse direction, so to speak. (See Lueger, Lexikon dertechnik fourth edition, volume 1 and 14, pages 587 and 589, and pages 521, 522).
  • the aim is to create a device with which great turbulence can be achieved in an economical manner.
  • the device according to the invention is characterized by at least two pump impellers which are parallel to one another and coaxially arranged with respect to one another for the partial flows, adjacent pump impellers being in opposite directions.
  • Fig. 1 there are two pump impellers 1 and 2 which are parallel and coaxial to each other. Both pump impellers 1 and 2 rotate about one and the same axis 3, but in the opposite direction of rotation. A first part flow flows in the direction of the arrows 4 to the pump impeller 1, and a second part flow flows in the direction of the arrows 5 to the second pump impeller 2.
  • the first partial flow 6 emerges from the pump impeller 1 as a rotating medium disk
  • the second partial stream 7 likewise emerges from the pump impeller 2 as a rotating medium disk. Both media discs 6 and 7 rotate in opposite directions.
  • the two pump impellers 1 and 2 are expediently designed identically to one another and consequently, apart from the direction of rotation, have the same hydrodynamic characteristics.
  • the two oppositely rotating liquid disks 6 and 7 touch each other in the envelope 8, the two opposite circumferential components of the two liquid whey disks meeting each other and canceling each other practically immediately.
  • the two liquid disks 6 and 7 have low radial speed components that determine the throughput of the pump impellers. Because of the sudden abolition of the mutually opposed tangential speed components, oscillating transverse movements of the liquid particles occur, which result in a very large amount of turbulence in the liquid region 9.
  • the two pump impellers 1 and 2 are shown somewhat more clearly.
  • the pump impeller 1 is carried by a hollow shaft 10, and the pump impeller 2 is seated on an inner shaft 11 which is surrounded by the hollow shaft 10.
  • the pump impeller 1 has a suction nozzle 12 for the partial flow 4
  • the pump impeller 2 has a suction nozzle 13 for the partial flow 5. Both pump impellers 1 and 2 rotate in opposite directions about the axis 3.
  • the two pump impellers 1 and 2 are driven by a single drive motor 14 for rotating in opposite directions.
  • the pump impeller 1 sits on the hollow shaft 10 and the pump impeller 2 is carried by the inner shaft 11.
  • the drive motor 14 drives via a belt 15 on pinions 16 and 17.
  • the pinion 17 is rotatably connected to the inner shaft 11.
  • the pinion 16 is rotatably connected to a wheel 18 which meshes with a wheel 19 which is rotatably connected to the hollow shaft 10. In this way, the two shafts 10 and 11 are driven in opposite directions.
  • the two pump impellers 1 and 2 are driven in opposite directions by two drive motors 20 and 21.
  • the motor 20 drives directly on the inner shaft 11 on which the pump impeller 2 is seated, and the motor 21 drives via a belt 22 on a pulley 23 which is connected to the hollow shaft 10 in a rotationally fixed manner.
  • the two motors 20 and 21 have opposite directions of rotation.
  • the pump impeller 1 is seated on a shaft 24, and the pump impeller 2 is seated on a shaft 25.
  • the two coaxial drive shafts 24 and 25 of the two pump impellers 1 and 2 are thus on opposite sides of the pump impellers.
  • a motor 26 is used to drive the shaft 24 and thus the pump impeller 1
  • a motor 27 is used to drive the shaft 25 and thus the pump impeller 2.
  • An intake port 28 leads to the pump impeller 1 and an intake port 29 leads to the pump impeller 2 merged flow media flow away via a nozzle 30.
  • the pump impellers 1 and 2 are designed as centrifugal wheels. If the pump impellers 1 and 2 have forward curved blades, the peripheral component of the speed of the emerging liquid disks 6 and 7 can be increased very much. The circumferential component of the speed (tangential speed) of the two liquid disks 6 and 7 can be set correspondingly large by appropriate speed of the pump impellers 1 and 2.
