Definitions
- the present invention relates to a nozzle arrangement according to the preamble of claim 1.
- a nozzle according to the preamble of claim 1 is known (US -A- 4,018,483).
- the Parts collected Through one, also in the nozzle gap, on the pressure pipe opposite end of the intake manifold, the Parts collected.
- With tear-off edges and others A targeted turbulence of the flow in the gap becomes the means achieved, which facilitates the inclusion of the parts.
- the required compressor capacity should be compared to the known Suction arrangements are smaller and also optimally used will; the transport fluid must be light on the respective task, i.e. to those to be transported Particles and / or similar or different types of other fluid, even under changing operating conditions, be customizable during use.
- a major advantage of this solution is that the shear forces generated by the guided pressure flow the particles to be absorbed and / or other fluids freed from their base and set in motion, so making them lighter then means less energy and at lower speeds can.
- the suction flow is expediently quantitative greater than the pressure flow.
- release agents listed by way of example in claim 1 are by no means to be considered conclusively; you can by other process engineering means known per se and chemical / physical processes such as ion exchangers, Cold traps etc. are supplemented or replaced.
- the demolition part according to claim 2 is used for targeted vortex formation and beam steering and is advantageously additional provided for a tear-off edge.
- a pulsator in the area of the nozzle gap be attached, the elastic or articulated is.
- This pulsator detaches the Coanda flow serving, impulsive turbulence in the work area. This creates transient processes in a targeted manner, which a corresponding, complex control of the pressure flow replace.
- the further developed arrangement according to claim 4 allows one Adaptation of the currents to the working conditions and the media to be transported. You can also, under Use suitable actuators, the flow conditions regulate in operation.
- a powered or auto-rotating Brush applied, either directly to the machined Pad touched, or is above this pad and only affects the cross-directional currents and thereby record the media to be transported helps.
- connection of pressure and suction lines to a common one Drive unit, claim 8 is particularly energy-saving and has a positive impact in addition to the high level of economy on the noise emission.
- a preferred use of the subject of the invention is in mobile cleaning machines for walkable and passable areas to see claim 10.
- the drying and degassing according to claim 11 is general Process engineering, but also in civil engineering (Road construction) of importance.
- a pressure nozzle part is designated 1; a Suction nozzle part with 2.
- the pressure nozzle part 1 is on the Pressure line 3 connected, the elongated connection opening 4 between the line 3 and the pressure nozzle part 1 serves as a passage.
- the suction nozzle part 2 is with the Line 5 for suctioned fluid, possibly with suctioned solid particles, via an elongated connection opening 6 between the line 5 and the suction nozzle part 2 connected.
- Both nozzle parts 1 and 2 are guided along an inner tube 8. From the outside On the side, the nozzle parts are formed by outer guide walls 9. The left outer guide wall is outwards, that means bent down and thus forms an edge 9a.
- a pressure flow is symbolized by reference number 10, with the reference numeral 10a a suction flow.
- a Bracing 11 fixes lines 3 and 5.
- a web 12 connects the lines 3 and 5 mentioned with the central Tube 8.
- the inner guide walls formed by the tube 8, such as those of the wall 9 are also smooth.
- a dashed, imaginary plane E is from Nozzle gap 7 determined in their position; pressurized the pressure nozzle 1 this - imaginary - plane at an acute angle, designated with a.
- Fig. 2 shows the already mentioned line 3 for extracted media and the left outer guide wall 9 with the outside curved edge 9a.
- a flange-like cover 14, cf. Fig. 1 is removable, which allows cleaning of the inside.
- Another cover 15, in the left part of FIG. 2, is fixed.
- the reference numeral 16 is a connector designated for lines 3 and 5, which in notoriously known way of coupling with suction and pressure lines serves to a fan, not shown to lead.
- Fig. 3 shows a variant of Fig. 1 and 2, in which one Compressed air line 3 in the middle by means of the connecting part 16a the compressed air is supplied.
- the outer guide walls 9 taper down towards the nozzle gap. - How 2, covers 14 and 15 are again provided.
- Tube 8 is to be replaced by a ball.
- a nose-shaped angle body 21 is indicated, an additional constriction between the nozzle gap 7 and the surface to be machined.
- Fig. 5 shows a nose-shaped body 22 which is rounded and is rigid or flexible. This also changes the Flow conditions in the gap 7, but not to the extent like the aforementioned angular body 21.
- Both bodies 21 and 22 cause a change in direction of the Coanda flow and thus serve the intended transient Vortex formation.
- Fig. 6 shows the surface M to be machined and, among other things. also a pulsator 24 which is elastic or articulated on the guide wall 9 is attached and the generation of vibrations in the flow 10 and thereby also in the flow 10a serves.
- the direction of vibration of the pulsator 24 is by a Double arrow indicated.
- FIG. 7 again shows the area M to be machined, and in addition a secondary flow 23 through nozzle-shaped holes or Longitudinal slots 23a leads in the outer guide wall 9. Also this additional stream 23 acts on the working area of the Nozzle arrangement.
- An additional overpressure p in the tube 8 forms through a bore 19 or a gap or more holes 19 another flow acting centrally in the work area, symbolized by a dashed arrow 20.
- the overpressure p can be easily controlled and can act as an additional flow be used intermittently.
- Fig. 8 shows a rotating brush 25, which in this case is driven by the flow 10 and 10a. It is of course, it is also possible that this with an electric motor or for example a turbine, additionally in Rotating arrow direction, is driven.
- This brush helps the solid particles in the area of the To convey nozzle gap 7, where it from the suction flow 10a be recorded.
- Fig. 9 shows the appropriate division and management of Pressure flow through an intermediate wall 26a (as a bold line drawn) with the resulting speeds cl and c2, where c1> c2. This works in the nozzle gap ideal in connection with an outward curved edge 9a in the guide wall and increases the conveying capacity of the arrangement.
- the suction nozzle part 2 shows another variant of the nozzle arrangement.
- the Pressure nozzle part 1 leads the compressed air flow 10 to the center of the nozzle gap 7. With this arrangement, the shear force acts concentric on the surface of the to be processed Area M.
- the suction nozzle part 2 sucks from the nozzle gap 7 the media to be transported with formation of axially parallel vortices - as indicated in the drawing - from.
- the outer guide walls 9 form a flat box in which of above the pipes for the pressure flow 10 and the suction flow 10a are let in.
- the suction nozzle part 2 consists of a tubular part 2 'and a concentrically resulting Guide flange 2 ", which laterally to the box shape the guide walls 9 is adapted.
- the surface F is the one already described Coanda flow and is replaced by the edges K.
- the connecting lines 30 for circulation carry the Suction flow 10a in the conveyor and / or separator and / or Capacitor 27, which is provided with a bypass 28. Further Connection lines 31 connect a compressor 29 for the recirculation with the pressure nozzle part 1.
- FIGS. 11 and 12 This possibility is outlined in FIGS. 11 and 12, wherein in the box bent tabs are designated 33; the resulting vortex flow is again indicated by arrows 18 indicated.
- the structural design is free within wide limits and also allows adjustments to the desired appearance (Design) ⁇
- Process engineering cycles are also conceivable in which for example an inert transport medium is used, which bypasses to a constant concentration value is held or replenished.
