Definitions

  • the invention relates to a conveyor device with an impeller for moving gases or liquids in a flow channel.
  • conveying devices are known in which an impeller is driven via a long shaft of a motor lying outside the flow channel, the latter having a curvature for the passage of the shaft into the flow channel so that the motor shaft can directly support the impeller.
  • the curvature in the flow channel immediately in front of the impeller causes a significant drop in performance and the long shaft requires high-precision manufacture and good maintenance.
  • the shaft carrying the impeller can also be driven by a motor, so that no curvature of the flow channel is necessary, but losses also occur.
  • a further problem is the sealing of the flow channel at the openings for the shaft or for other parts of an implementation. This is of great importance especially when conveying dangerous media.
  • the object of the present invention is to find a conveyor device in which the above-mentioned problems do not occur or are at least reduced.
  • a drive device consisting of a stator and an armature is used for the rotation of the impeller, which is designed as a ring which concentrically surrounds the impeller rotatable about an axis and which forms a unit with the impeller.
  • the stator is thus on the circumference of the flow channel and can be cooled from the outside to convey hot media and the flow in the middle of the flow channel is not hindered.
  • the object is also achieved according to the invention by a conveying device in which an outer impeller driven by a drive device drives a smaller, inner impeller through its rotation via a gear, thereby ensuring a uniform flow over the entire flow cross section.
  • the outer impeller is preferably operated by an electric motor, the armature of which is annular and concentrically surrounds the impeller. Due to the improved conveyance of the central flow in the flow channel, however, the drive of the outer impeller by a motor located outside the flow channel is also possible.
  • Permanent magnets can be arranged in the ring-shaped armature, which follow the rotating field generated by the coils located in the stator.
  • the use of permanent magnets is particularly advantageous for safety reasons in the case of highly flammable gases.
  • another drive device for example an asynchronous motor with a short-circuit rotor, must be selected, with electrically conductive, rods parallel to the axis of rotation of the impeller and coils which generate the magnetic rotating field are located in the stator.
  • the impeller can be driven by the ring-shaped armature being designed as a turbine wheel, to which a gaseous or liquid pressurized drive medium is fed via nozzles located in the stator. Part of the medium to be pumped can serve as the drive medium after compression.
  • the armature can run in a recess in the stator.
  • the gear provided between the outer impeller and the inner impeller can consist of two ball bearings, the outer impeller sitting on the outer ring of the first ball bearing, the inner ring of which is fixed in relation to the flow channel, the outer ring of the first ball bearing with the cage of the second ball bearing is connected, the inner ring of which is integral with or connected to the axis of the inner impeller, whereas the outer ring of the second ball bearing is fixed with respect to the flow channel.
  • FIG. 1 shows a conveyor device according to the present invention in section.
  • 2 shows the conveyor device from FIG. 1 in a partially sectioned view in the flow direction.
  • 3 shows another embodiment of the invention in section.
  • FIG 4 shows a further exemplary embodiment in a view in the flow direction.
  • Figures 1 and 2 show a flow channel 8, in which there is an impeller 3 which is rotatably mounted on a frame 9 which is stationary with respect to the flow channel 8.
  • the blades of the impeller 3 are fixedly connected at their outer ends to a ring which is the armature 1 of an electric motor.
  • armature 1 there are electrically conductive rods 4 running parallel to the axis of rotation, e.g. made of copper, which are connected via short-circuit rings 10.
  • the stator 6 is formed with coils 5, which generate a magnetic rotating field and thus move the armature 1 and the impeller 3 at the same time. In order not to influence the edge currents too much, the armature 1 runs in a radial recess 7 of the stator.
  • the embodiment of the invention shown in Figure 3 shows an outer impeller 23 with small, outer blades, which is mounted on a first ball bearing 21 on the fixed to the flow channel 8 frame 9 connected to the inner ring 26 of the ball bearing 21.
  • the outer ring 25 of the first ball bearing 21 is connected to the cage 27 of a second ball bearing 22, the outer ring 29 of which is fastened to the walls of the flow channel 8 via supports 31 and the inner ring 28 of which is connected to the axis 30 of a small, inner impeller 24.
  • the outer impeller 23 is, like the impeller shown in Fig.l and 2, driven by an electric motor, the armature 1 concentrically surrounds the impeller 23 as a ring and is firmly connected to the impeller.
  • the stator 6 of the electric motor is arranged with the coils 5 outside the flow channel, where it can be easily cooled if necessary when conveying hot media.
  • the rotation of the impeller 23 rotates the outer ring 25 of the first ball bearing 21, which takes the cage 27 of the second ball bearing 22 with it and in this way sets the inner ring 28 of the second ball bearing 22 in rotation with respect to the fixedly arranged outer ring 29.
  • This translation causes the inner impeller 24 to rotate at a higher speed than the outer one Impeller 23 and ensures a good central flow.
  • FIG. 4 shows an embodiment of the device according to the invention in which the armature 41 is also firmly connected to the impeller 33 and has the shape of a ring which is designed like a turbine wheel.
  • the drive takes place via a pressurized drive medium which is directed through nozzles 35 located in the stator 36 onto the blade elements 34 of the armature 41.
  • the drive medium can be gaseous or liquid. A part of the medium to be conveyed can be used as the drive medium, whereby this is first compressed and then fed to the nozzles.
