Definitions

  • the present invention relates to a suction nozzle according to the preamble of claims 1 and 3.
  • Known nozzles usually work more or less orthogonally to a surface and tend if they are not on the surface are led, for gluing, i.e. the suction opening sucks gets stuck on the surface to be worked and prevented the removal of the particles and / or the fluid.
  • a vacuum cleaner nozzle according to the preamble of claim 1 is known from FR -A- 779498.
  • This nozzle has a relative wide base area, which is traversed by grooves is that of the periphery of the nozzle body, guided linearly what tangentially flow into the bore of the suction pipe a circular flow in the pipe causes.
  • This vacuum cleaner nozzle requires good ground contact in the Area of the intake manifold; if this is not available, so there is no circular flow.
  • the necessary long grooves are energetically very unfavorable and impair the suction effect of the nozzle.
  • this nozzle is said to be only slight in its operation Make noise and not clog the suction opening tend.
  • the nozzle should also be one for heat exchanger, chimney and Form material separator applications for favorable flow.
  • the advantage of the invention can be seen in the fact that The embodiment described creates a vortex in the suction nozzle, being in the suction opening and below this one Shear force is formed, which is to be removed solid particles and / or fluid peels off and in motion puts.
  • the nozzle expediently has a tubular shape; she could but, if structural dimensions require it, also as a duct be executed.
  • the concentric collar mentioned in claim 2 allows the Favorable suction effect to extend beyond the suction opening.
  • independent claim 3 is particularly advantageous; it could be used in practice due to its small dimensions for cleaning devices of almost any kind, as well as in particular use for street sweepers etc. That in addition pressure nozzle part provided to the suction nozzle tube acts from the edge areas with the resulting shear force to the central Suction opening and supports vortex formation.
  • the tear-off edge listed in claim 4 is used for support the separation of the interface flow in the work area the nozzle.
  • the method according to claim 5 brings about in a simple manner also one of the receptacles of the medium inside the suction nozzle tube serving opposite, spiral vortex formation.
  • the pressure ratios can be achieved overlay the desired shear effect in the work area and adjust.
  • the setting of the ratios can be done empirically Changing the geometric relationships or by a corresponding one Splitting the partial flows can be achieved.
  • the development according to claim 7 uses the known Coanda effect for targeted flow control.
  • Fig. 1 is a vertical sectional view of a suction nozzle tube designated 1; the suction direction 2 is with a vertical arrow indicated.
  • the suction nozzle tube 1 is below provided with an outwardly curved tab 3 and on top connected to a suction line SL.
  • the area around the suction opening 6 of the suction nozzle tube 1 has a concentric Collar 5 on. The resulting flows are with straight or curved arrows 12 drawn.
  • FIG. 3 the tabs 4, which act analogously to FIGS. 1 and 2, are bent towards the inside of the pipe.
  • the tangential to the suction direction 2 flow 12 acting through the opening 7 also results in a circular flow and is through a corresponding one labeled circular arrow.
  • FIGS. 5 and 6 again shows externally curved tabs 3, only these are compared to FIG. 1 and 2 flat and thus form larger openings 7.
  • FIGS. 1 to 5 While in the exemplary embodiments FIGS. 1 to 5 only one or four lobes 3 and 4 are designated, show the Representations Fig. 7 to 10 each eight inwards or towards rags curved on the outside.
  • Vortex flow arises are in a box with rectangular base two nozzles 12a are provided, in which an air flow led through pressure nozzle parts 8 starts.
  • the working area of the suction opening 6 is simultaneously with the eddy current in the suction nozzle flow 1 and with the shear force resulting from the separate nozzles 12a Currents burdened, so possibly on a pad adhering particles or gases detached from high density and, since already in motion, with a very low suction power required can be removed.
  • the size of the flow area 6 '' and its angle of attack ⁇ can be adjusted to those in the suction opening Adjust the pressure and swirl ratios easily, as the a Coanda effect resulting from this configuration enables optimal beam steering.
  • the beam serves, in a manner known per se, a tear-off edge K.
  • suction nozzle tube 1 as the suction nozzle part 9 with the unbent Surfaces 6 '' formed in one piece.
  • the nozzle can also be rotationally symmetrical be designed; this will have the same effect with a achieved single nozzle 12a.
  • the gases extracted from the surface M to be processed or the solids contained in the flow are in the suction direction 2 by connecting lines with connected known filters and / or separators 13 and / or Capacitors, catalysts, etc. removed in a targeted manner.
  • a bypass 14 can emerge from these devices Can be recirculated, for example by a Connection to the pressure nozzle parts 8.
  • a suitable compressor 15, for example a one or multi-stage axial or radial fan allows over its inlets and outlets a very energy-saving operation the nozzle with optimal effect.
