Definitions

  • the invention relates to a jet nozzle provided for use in devices for cleaning stone and / or metal surfaces, in particular, having a rotationally symmetrical chamber which has an axial inlet for a detergent mixture and an axial outlet with an adjoining outlet nozzle for the detergent.
  • Mixture wherein the rotationally symmetrical chamber on its inner wall has guiding devices for influencing the flow of the cleaning agent mixture, which are designed in the manner of guiding vanes which protrude into the interior of the chamber and whose surfaces are adjusted relative to the longitudinal axis of the chamber are.
  • Such a jet nozzle is known from German Patent No. 206 610.
  • the jet nozzle described therein is intended in particular for use as a sandblasting nozzle, in which the guiding devices are designed as helically extending ridges or depressions, e.g. are formed as grooves cut into the inner wall.
  • the trains formed from ridges, ribs or grooves abut each other directly, so that no cylindrical outer surfaces remain between them.
  • the detergent mixture introduced through the axial inlet is brought into a helical movement or rotation and then emerges from the axial outlet and the outlet nozzle onto the surface to be cleaned, but with because of the rotation, it is avoided that the cleaning agent mixture jet strikes perpendicular, rather it is guided approximately tangentially over the surface to be cleaned, and as a result the solid particles contained in the cleaning agent mixture, in the known jet nozzle just the sand passed through, are particularly good cleaning, namely "wiping" effect can develop.
  • the stream of detergent mixture passed through the jet nozzle is not completely set into the desired helical rotational movement over its entire flow cross section. Because of the relatively high flow velocity and the relatively short length of such a jet nozzle, a non-rotating, but only linearly progressing core area remains in the detergent mixture stream. This means that part of the detergent mixture, in particular the particles contained therein, directly impact the surfaces to be cleaned.
  • the swirl blades in particular wear out very quickly due to the mixture of cleaning agents passing them and causing them to rotate, and this insert body therefore has to be replaced frequently. But even in this known embodiment, a non-rotating, but only linearly progressing core area remains in the detergent mixture stream, because the swirl vanes do not reach the center of the cross section of the jet nozzle, if this were the case, the swirl vanes would be an even larger one Subject to wear and tear.
  • a move has been made to add a part of the total detergent mixture, for example the air / granulate mixture, to the axially entering water only later, namely in Area of the jet nozzle chamber.
  • a corresponding inlet nozzle was provided on the side of the jet nozzle at an angle to the longitudinal axis of the nozzle, for example 15 to 30 °, through which the air-granulate mixture enters the chamber.
  • Such a jet nozzle is described in EP 0 171 448.
  • a disadvantage of such nozzles is that due to the eccentric introduction of a part of the total mixture, specifically the air / granulate mixture, this strikes the wall of the chamber opposite the entry point and this part of the chamber is subject to extremely high wear.
  • DE-PS 40 02 787 describes a jet nozzle which has special material inserts at the points to be protected from wear.
  • the invention is based on the object of designing a jet nozzle in such a way that it is subjected to uniform wear and in particular forms such a stream of cleaning agent mixture which rotates helically over its entire cross section, the rotation being free adjusted and thus the wear of the control equipment can be minimized.
  • This lengthwise design of the guide vanes ensures that the detergent mixture stream is converted into a helical rotation over its entire cross-section and not, as described in detail above in the description of the prior art, a straight line flowing core of the detergent mixture is retained, which can have a destructive effect when striking the surfaces to be cleaned.
  • the adjustability of the guide vanes also allows the basically desired rotation to be set to different degrees, and without further ado during the cleaning process. This makes the blasting nozzle according to the invention more flexible in use, because the cleaning of different surfaces such as natural stone, wood, metals, plastics, paintings, frescoes, etc., due to their specific material and / or structural properties, requires a blasting technique that makes it possible to always continuously adapting to changing surface conditions.
  • the natural stone material is inherently extremely inhomogeneous, particularly with regard to its hardness, and its weathering due to environmental influences varies depending on the object.
  • the calcium carbonate binder contained in natural stone is converted to calcium sulfate by SO2 and leaches the calcium carbonate binder to different depths out of the stone structure and forms a more or less thick gypsum crust on the surface, with the intermediate layer from still intact natural stone to the surface crust has different strength. It is precisely this inhomogeneity that requires a jet nozzle, which makes it possible to adapt the efficiency during the cleaning process to these constantly changing conditions.
  • this problem described using the example of natural stone also applies to almost all inorganic and organic materials, but in particular also to objects that are constructed from mixed masonry, such as granite, marble, terracotta etc.
  • this novel jet nozzle has the advantage that the guide blades wear out much more slowly because they do not have to work constantly in the highest power range.
  • the adjustable guide vanes are advantageously arranged on the inner wall of a hollow cylindrical insert which can be inserted into the chamber. Since the detergent mixture naturally not only frees the surfaces to be cleaned of dirt, but also wears the contact surfaces of the guide blades and the chamber, that is to say the inner wall thereof, it is advantageous to design these parts interchangeably, for which the hollow-cylindrical insert described above is particularly suitable.
  • the guide blades are interchangeably arranged in the insert. Since the guide blades are of course particularly exposed to wear and therefore have to be replaced rather than the ring-shaped insert itself, it is provided that the guide blades can be inserted or removed individually from the insert.
  • the insert is advantageously arranged adjacent to the outlet nozzle.
  • This arrangement of the insert within the chamber of the jet nozzle means that the insert can be exchanged very easily or the guide vanes can be replaced, because it is sufficient if only the outlet nozzle is detached from the chamber, the insert itself can then be removed from the chamber without further ado be pulled out.
  • guide devices are provided on the inside of the chamber and, viewed in the direction of flow, upstream of the guide vanes, which are arranged as helical on the inner wall of the chamber Channels and intermediate webs are formed.
  • These guide devices have the advantage that they give the cleaning agent mixture entering at the axial inlet of the jet nozzle a pre-rotation before entering the area of the guide vanes and thereby reduce the stress on the guide vanes, ie increase their service life.
  • These helically extending channels and webs are advantageously formed on the inside of an insert that can be inserted or inserted into the chamber.
  • This training corresponds to the training of the use provided with guide vanes and already described above. This makes it possible to easily replace the channels and webs that are subject to wear in the chamber of the jet nozzle.
  • the channels preferably have a U-shaped cross section.
  • This training is particularly well suited to impart a helical rotation to the detergent mixture flow.
  • a prechamber is provided after its axial inlet, which has a radial inlet.
  • water can be added to the detergent mixture entering the chamber through the axial inlet, which consists, for example, of air and granules, and thus a corresponding mixing ratio can be produced directly at the jet nozzle, the water or water vapor being the carrier medium air gives a higher density and the granulate finely distributed therein assumes a more intensive and higher rotation speed and considerably increases the intensity of the cleaning effect.
  • the radial inlet preferably opens into the prechamber in the form of a nozzle.
  • this nozzle results in a particularly fine atomization of the water or water vapor, it is dispersed in the compressed air / granulate mixture and thus achieves a higher density and the finely distributed This gives granules a higher rotational speed and thus intensifies the cleaning effect.
  • the jet nozzle 1 shown in FIG. 1 essentially consists of a chamber 2, which forms the central component and is of a rotationally symmetrical and hollow cylindrical design, which has an axial inlet 3 and an axial outlet 4 for the detergent mixture stream to be passed through.
  • the inner wall 5 of the chamber 2 has an internal thread 6, into which a hose attachment 7 formed in a known manner is screwed and sealed off from the chamber 2 by means of an O-ring 8.
  • an outlet nozzle 9 shown in FIG. 3 is provided, which is screwed onto the outer wall 13 of the axial outlet 4, which has an external thread 12, by means of a union nut 10, which has an internal thread 11.
  • the outlet nozzle 9 has a conical configuration, in particular of the inner wall 14, with a diameter that tapers towards the opening end 15 of the outlet nozzle 9.
  • an insert 17 shown in FIGS. 4a and 4b is provided directly adjacent to the inlet end 16 of the outlet nozzle 9, which also has a hollow cylindrical configuration with an outer diameter that corresponds to the diameter of the interior corresponds to chamber 2.
  • This insert 17 is in turn provided with guide vanes 18 which can be adjusted with respect to the longitudinal axis 19 of the jet nozzle and which can impart a helical rotation to the cleaning agent mixture flowing through the jet nozzle.
  • the edges 20 of the guide vanes 18, which are directed against the flowing detergent mixture, are pointed to provide less resistance to the inflowing detergent mixture.
  • the rear edges 21 of the guide blades 18, however, are rounded off in a simple manner. For this purpose, reference is made to FIG. 4a.
  • the adjustable guide vanes 18 can be actuated by means of actuating levers 23 via pins 23 ′ that pass through the walls of the chamber 2 and the insert 17 are rotated, recesses 22 'being provided in the inner wall 22 of the insert 17, in which the guide blades 18 can be pivoted.
  • a further insert 24 is provided in the chamber 2, which directly adjoins the insert 17, but has a greater length than this.
  • This insert 24 is provided on its inner wall 25 with channels 26 which run helically and have a U-shaped cross section.
  • the channels 26 are not arranged directly adjacent to one another in the inner wall 25 of the insert 24, but are at a distance from one another. This distance between the channels 26 is formed by webs 27.
  • the insert 24 is used to set the flow of detergent mixture passed through it, at least in its outer regions, before it is passed through the insert 17, in a helical rotation; this in particular ensures that the insert 17 with the guide blades 18 wears down less quickly.
  • the adjustment of the channels 26 and webs 27 to the longitudinal axis 19 of the jet nozzle 1 corresponds to an average adjustment of the guide blades 15 in the insert 17.
  • This insert 24 is also designed to be interchangeable and can be easily pulled out of the interior of the chamber 2 after unscrewing the union nut 11 and after removing the outlet nozzle 9.
  • a prechamber 28 is provided in addition to the inserts 17 and 24, which connects directly to the axial inlet 3 of the chamber 2 and up to the Beginning of the insert 24 with the helical channels 26 and webs 27 is sufficient.
  • water can be introduced into the jet nozzle 1 if, for example for special reasons the water should not yet be added to the total detergent mixture entering through the axial inlet 3.
  • an injection nozzle 31 is advantageously provided in the radial inlet 24 for this purpose.
  • the relaxation of the introduced water in the antechamber caused by this nozzle ensures the preparation of an intensive detergent mixture in the form of a dispersion containing the detergent (substrate).
  • a cleaning agent mixture jet can be formed which executes a helical rotational movement over its entire cross section and consequently exerts an excellent cleaning effect on the surfaces to be cleaned, the intensity of the rotation being adjustable and thus the cleaning effect of the nozzle can be metered.
  • the jet nozzle according to the invention can be used in the low-pressure as well as in the high-pressure area and is not only suitable for cleaning stone and metal surfaces, but also for cleaning wood and plastic surfaces because of its variable use.
