Definitions

  • the invention relates to a long throw nozzle with adjustable throughput and throw distance.
  • Long throw nozzles are mainly used in large rooms where large penetration depths of the blown air are required. Since the emerging air jet is guided through the nozzle, the jet direction is not disturbed by the type of air supply. With a good design, the volume is relatively low despite the high exit speeds. Long throw nozzles are used especially in high production halls, gymnasiums, festival halls, but also in smaller rooms, such as meeting rooms, especially in smaller rooms when, for architectural reasons, no supply air can be blown in through the ceiling.
  • blow-out grilles are used in most cases, since these are easier to adapt to the requirements of the individual case.
  • the invention has for its object to design a long throw nozzle so that the throughput and throwing distance can be set in a very simple manner, so that on the one hand the fluidic advantage of a long throw nozzle can be fully exploited and on the other hand the disadvantage of a single production for jaden specific installation is unnecessary .
  • the nozzle has a wide inlet frame of constant diameter and an adjoining tapered nozzle jacket, which is conical over most of its axial extent to the outer end of the nozzle, the conical part being shortenable.
  • the shortening can be achieved by simply cutting off the conical part of the nozzle shell, so that a single nozzle shape between a minimum outlet diameter (without cutting) and a maximum outlet diameter can be adapted to the respective requirements for throughput and throwing distance. With the injection pressure remaining the same, of course not only the throughput quantity but also the throwing distance depends on the outlet cross-section. A maximum outlet cross-section, at which a remainder of the conical nozzle jacket remains, should not be exceeded for the nozzle function to function properly.
  • the provided inlet frame of constant diameter causes low pressure losses with a low nozzle volume despite the high blowing speed " .
  • a throughput range of about 1:10 can be covered by shortening the nozzle jacket accordingly.
  • the entire practically predominant range from about 10m 3 / h to 2000 m 3 / h can be covered. This results in extremely efficient production and warehousing.
  • the long-throw nozzle according to the invention can be pressed from steel or aluminum or injected from plastic. In any case, it can advantageously be used in such a way that an axial section of the conical part of the nozzle shell is cut off in a plane perpendicular to the nozzle axis in order to adapt to a specific throughput quantity and / or throwing distance.
  • the throwing distance can also be influenced very simply in that a swirl-generating grid is installed in the inlet frame.
  • the rotation generated by the grid is further increased as it passes through the conical nozzle shell.
  • a reduction of the throwing distance by about 40% is possible under otherwise constant conditions.
  • the beam can be directed parallel to the ceiling, for example, so that it only detaches from the ceiling after a certain throw and sinks downward.
  • the swiveling of the spherical cap holding the nozzle is preferably provided on all sides.
  • the calotte can also be expediently connected to a motorized swivel drive, in particular if it is arranged in places in the room which are difficult to access or reach.
  • nozzles of the same type can be inserted next to one another in one or more plates, for example arranged in rows or in a grid pattern next to one another.
  • the long-throw nozzle 11 shown in FIG. 1 has an inlet frame 10 with a constant diameter and an adjoining nozzle jacket 12, the major part 14 of which extends conically up to the outer end 16.
  • the outer end 16 has a minimum diameter d min auf which generates a certain throughput quantity and throwing distance at a given injection pressure. If the throughput quantity and / or throwing distance are to be changed, a more or less long axial section of the conical part 14 can be cut off in a plane perpendicular to the nozzle axis 18, depending on the requirement.
  • a cutting plane 20 corresponding to a maximum diameter .d max should not be exceeded, since otherwise a perfect nozzle effect of the nozzle jacket 12 can no longer be achieved.
  • two long-throw nozzles 10, 12 are inserted into the wall 22 of a ventilation duct with a circular cross section shown in section.
  • the inlet frame 10 is extended in this embodiment by a separate mounting piece.
  • FIG. 5 shows an embodiment with two nozzles 11 attached to a ventilation duct 22 shown in cross section with a square cross section, wherein in addition a guide surface 26 which guides the air into the nozzles 11 is shown.
  • FIGS. 6 and 7 show an embodiment in which a grid-like arrangement of the same long throw nozzles 11 is installed in a common plate 24.
  • FIGS. 8 and 9 show an embodiment of the long-throw nozzle 11 in which the inlet frame 10 and the nozzle jacket 12 in a hemispherical dome 26 are belfestiert.
  • the spherical cap 26 is in turn pivotally supported on all sides in an outer frame 28, the outer edge 28 having a square outer plate 30 for installation in a wall or channel opening 32. If the wall opening 32 is located in a side wall near the ceiling of the room to be ventilated, the nozzle jacket 12 can be pivoted, for example, when cold air is introduced into the upper position 12 ', indicated by dash-dotted lines, while it is dashed when warm air is supplied into the lower one drawn position 12 "can be pivoted.
  • two pivotable nozzles according to FIG. 8 are used next to one another and can be pivoted together on a common shaft 36 by means of a pivot drive 34.
  • FIG. 11 A similar arrangement with a single nozzle is shown in FIG. 11, a swivel drive 34 being able to pivot both about the shaft 36 lying in the plane of the drawing and about an axis 38 perpendicular to the plane of the drawing.
  • the outer frame 28 supporting the spherical cap 26 can have a circular outer plate 30 ', a square outer plate 30 "or a hexagonal outer plate 30"'.
  • the square outer plate 30 " can be installed according to FIG. 1G in a row and column-shaped grid of a plurality of similar nozzles or according to FIG. 17 in a grid with staggered lines. According to FIG. 18, the hexagonal outer plate 30" 'can be installed in a honeycomb pattern to be built in.
  • FIG. 16 A schematic partial side view of the arrangement according to FIG. 16 or also a single column arrangement of three swiveling nozzles 11 seated one above the other, which are inserted into a wall opening 32, is shown in FIG. 19.
  • FIG. 20 to 22 An embodiment of the long throw nozzle according to the invention with swirl generation for reducing the throw distance is shown in Figures 20 to 22.
  • a swirl generating circular grid 40 is inserted into the inlet surface of the lead frame 10.
  • the grating 40 consists of a plurality of rings 42 of webs 44 inclined at an angle ⁇ with respect to the plane of the grating. The smaller the angle ", the greater the swirl-generating effect of the grating 40.
  • the strength of the twist can therefore be selected by selecting the angle ⁇ of the air jet emerging from the nozzle and thus the throwing distance can be set within wide limits, together with the shortening of the nozzle jacket 12 according to the invention, any desired throughput quantity and throwing distance can thus be achieved with a single nozzle shape.
