Definitions

  • the present invention relates to a fan housing having a flow passage with a one-sided suction port and a discharge opening on the other side, as defined in the preamble of claim 1.
  • a fan housing is known e.g. from US-A-3 531 221.
  • Fans are often used for applications in which it depends on a very uniform, especially over the entire flow cross-section away as laminar as possible air flow.
  • axial fans are used side by side, particularly in a row arrangement, in order to apply a stream of air to large sheets of paper after printing, so that these sheets can be deposited more quickly on a piece of paper.
  • the highest possible fluidic surface pressure is to be caused, which acts on the sheet, thereby supporting the gravitational force in the storage of the sheets and thus pushes out the obstructive and last filed sheet on the underside of the sheet and the tray hindering air.
  • the filing speed and filing quality have a direct influence on the profitability of a printing press, since they decisively determine the throughput speed of the printing press. An improvement of the filing and an increase in the filing speed would therefore result in a direct increase in machine economy.
  • the present invention has for its object to improve a fan housing of the type described above, generic type with respect to the flow characteristics of the delivered air flow, in particular so that a with The fan housing according to the invention fan is particularly suitable for use in printing machines described above.
  • the invention is based on the recognition that, naturally, a free jet forms behind each fan, which mixes only after a certain distance with the ambient air and / or with the free jet of adjacent fans.
  • These free jets have the property that they have a relatively low degree of turbulence in the center.
  • the blown out, moving air mixes with the attracted, resting air in a shear layer (entrainment effect).
  • this shear layer exist almost exclusively large-scale, low-frequency vortex forms. These are long-lived due to their high energy content.
  • this has the consequence that is stimulated by the vortex shedding of the sheet to oscillate in its natural frequency. Under certain circumstances, even the natural frequency of the arc correlates with the vortex shedding frequency. This mechanism prevents an increase in the filing speed and can continue to lead to temporary disturbances of the filing process.
  • the drawing figures show an axial fan housing 1 with an axial flow passage 2 with a one-sided suction port 4 and an opposite one Blow-out opening 6.
  • the suction opening 4 and the blow-off opening 6 each have a circular outer contour. This results in a substantially annular configuration of the axial fan housing 1 (so-called wall ring).
  • centric holding means 8 are arranged for a motor / Lüfterradü, not shown, wherein the holding means 8 are connected via spoke-like connecting elements 10 with the outer housing ring.
  • an annular or circular disk-shaped flow cross section is thus formed.
  • the contour elements 14 are fixed with a base (in the illustrated case a triangle base) at the opening edge of the exhaust opening 6 or in the surrounding area of the housing end face, while with its opposite tip or edge (as shown in its triangular Tip) on the one hand axially in the flow direction and on the other hand obliquely radially inwardly or outwardly protrude. 1 and 2, all contour elements 14 are aligned obliquely axially and radially inwardly, namely at an angle ⁇ 1 to the radial plane (plane of the exhaust opening 6 and the housing end face), starting from the peripheral region of the exhaust opening. 6
  • part of the contour elements 14 are aligned at an angle ⁇ 2 obliquely axially and radially outwards.
  • ⁇ 1 obliquely radially inwardly projecting contour elements
  • ⁇ 2 obliquely radially outwardly projecting contour elements 14
  • angles ⁇ 1 and ⁇ 2 may be equal or different.
  • the respective angle ⁇ 1 or ⁇ 2 lies in the range between 0 ° and 90 ° and can - as well as the number, size and contour shape of the contour elements 14 - be adapted and adjusted to the particular application, with a combination of contour elements may be provided may differ from each other in shape and / or size and / or angular orientation.
  • FIGS. 1 and 2 exemplify a comparison of the operation of a non-inventive embodiment (Fig. 5) without Abströmkonturstoff 12 and the equally not-inventive embodiment of FIGS. 1 and 2 (Fig. 6).
  • Fig. 5 it is illustrated that in a conventional "normal" axial fan, an outer shear layer 16a is formed, which encloses an inner, undisturbed flow 18.
  • This outer shear layer 16a has a relatively large radially measured thickness d 1 and contains large-scale vortices and a large proportion of low-frequency excitation components. This leads to a non-stabilized air jet.
  • Fig. 6 it is clear from Fig. 6 that the embodiment of Figs.
