Definitions
- the invention relates to a for use in devices for cleaning provided by in particular stone and / or metal surfaces jet nozzle with a rotationally symmetrical chamber that has an axial inlet for a detergent mixture and an axial outlet with an adjoining outlet nozzle for the detergent mixture, the rotationally symmetrical Chamber designed guiding devices on its inner wall for influencing the flow of the detergent mixture, which in the manner of in the Interior of the chamber standing guide vanes are formed with their Areas are adjustable relative to the longitudinal axis of the chamber.
- a jet nozzle is known from US-A-1 510 174.
- Another jet nozzle is known from German Patent No. 206 610.
- the jet nozzle described therein is particularly suitable for use as Sandblasting nozzle is provided, in which the guide devices as helical elevations or depressions, e.g. than in the Grooves cut into the inner wall are formed.
- the increases, Ribs or grooves formed trains abut each other directly, so that no cylindrical outer surfaces remain between them.
- an appropriate Inlet nozzle on the side of the jet nozzle at an angle to the longitudinal axis of the nozzle provided for example 15 to 30 ° through which the air-granulate mixture in the Chamber enters.
- Such a jet nozzle is described in EP 0 171 448.
- a disadvantage of such Nozzle is that by eccentrically introducing part of the total mixture, specifically the air / granulate mixture, this on that of Entry point opposite wall of the chamber and this part of the Chamber is subject to extremely high wear. To such wear to prevent or at least reduce, for example, in DE-PS 40 02 787 describes a blasting nozzle that is attached to the before wear protective areas has special material inserts.
- the invention is now the The task is to design a jet nozzle so that it is uniform Wear is subject and in particular such a detergent mixture stream forms, which is helical over its entire cross section rotates, the rotation is freely adjusted and thus the wear of the control devices can be minimized.
- the guide blades extend radially up to the longitudinal axis of the chamber and have at least one axial length that is greater than its radial height.
- the radial height of the guide vanes ensures that the detergent mixture flow over its entire cross-section into one helical rotation is transferred and not, as in the above Description of the prior art described in detail, a straightforward flowing core of the detergent mixture is maintained, which at Impact on the surfaces to be cleaned can have a destructive effect.
- the Adjustability of the guide vanes also allows the basic to set the desired rotation to different degrees, without further ado during the cleaning process.
- the invention Blasting nozzle more flexible in use because the cleaning of different surfaces such as natural stone, wood, metals, plastics, paintings, frescoes etc. require due to their specific material and / or structural properties a blasting technique that makes it possible to keep changing Continuously adapt 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 SO 2 effects 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 ranging from still intact natural stone to 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 cleaning agent 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 purpose the hollow-cylindrical insert described above is used 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 exchanged, 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 designed as helically extending 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 the axial inlet of the jet nozzle a pre-rotation before entering the area of the guide blades and thereby reduce the stress on the guide blades, 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 the detergent mixture flow to impart a helical rotation.
- 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 giving 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 consists essentially of a central component forming and rotationally symmetrical and hollow cylindrical trained chamber 2, which has an axial inlet 3 and an axial outlet 4 for has the flow of detergent mixture to be passed.
- the inner wall 5 of the chamber 2 has Internal thread 6, in which a trained in a known manner Screwed hose connector 7 and opposite the chamber 2 is sealed by an O-ring 8.
- the outlet nozzle 9 has a conical design, in particular of the inner wall 14, namely with one towards the opening end 15 of the outlet nozzle 9 tapered diameter.
- Chamber 2 is immediately adjacent to the inlet end 16 of the outlet nozzle 9 in Fig. 4a and 4b insert 17 provided, which is also a has a hollow cylindrical configuration with an outer diameter that the Diameter of the interior of the chamber 2 corresponds.
- This insert 17 in turn is provided with guide vanes 18 which are opposite the longitudinal axis 19 the jet nozzle are adjustable and the one flowing through the jet nozzle Detergent mixture can impart a helical rotation.
- the edges 20 directed against the flowing detergent mixture Guide vanes 18 are pointed to the incoming cleaning agent mixture to oppose less resistance.
- the back edges 21 of the guide blades 18, however, are rounded in a simple manner. For this purpose, reference is made to FIG. 4a.
- the adjustable guide vanes 18 can be actuated by means of the actuating lever 23 the walls of the chamber 2 and the insert 17 pins 23 ' are rotated, 17 recesses in the inner wall 22 of the insert 22 'are provided, in which the guide blades 18 can be pivoted.
- a conceivable actuating lever 23 is not shown in the figures connecting control device, so that all three with a single handle guide vanes 18 shown in the figures are simultaneously adjusted by the same amount can be.
- 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 immediately adjacent to one another in the inner wall 25 the insert 24 arranged, but have a distance from each other. This distance between the channels 26 is formed by webs 27.
- the insert 24 serves to flow the detergent mixture through at least in its outer areas before being passed through the insert 17 in to offset a helical rotation, which in particular achieves that the insert 17 with the guide vanes 18 wears out 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 position of the guide vanes 15 in the insert 17.
- This insert 24 is also designed to be interchangeable and can be unscrewed the union nut 11 and after removing the outlet nozzle 9 without further ado the interior of the chamber 2 are pulled out.
- a prechamber 28 which is directly connected to the axial inlet 3 of the chamber 2 connects and to the beginning of the insert 24th with the helical channels 26 and webs 27 is sufficient.
- this antechamber 28 opens a radial outlet 29, which has an internal thread 30 for connecting a Has supply line, not shown.
- a radial inlet 29 can For example, water can be introduced into the jet nozzle 1 if, for example for special reasons the water has not yet passed through the axial inlet 3 entering total detergent mixture should be added.
- Injection nozzle 31 is provided in the radial inlet 24. That through this nozzle induced relaxation of the introduced water in the antechamber ensures the preparation of an intensive detergent mixture in Form of a dispersion containing the cleaning agent (substrate).
- the jet nozzle according to the invention can be used in both low pressure and High pressure area are used and is not only suitable for cleaning Stone and metal surfaces, but also because of their variable usability for cleaning wooden and plastic surfaces.

Description
Diese am Beispiel Naturstein beschriebene Problematik trifft auch auf fast alle anorganischen sowie organischen Materialien zu, insbesondere aber auch auf Objekte, die aus Mischmauerwerken konstruiert sind, wie z.B. Granit, Marmor, Terracotta etc..
Neben der vorbeschriebenen vorteilhaften Einstellbarkeit des Reinigungsmittel-Gemisch-Stromes besitzt diese neuartige Strahldüse noch den Vorteil, daß sich die Leit-Schaufeln wesentlich langsamer abnutzen, da sie nicht ständig im höchsten Leistungsbereich arbeiten müssen.
Da das Reinigungsmittel-Gemisch selbstverständlich nicht nur die zu reinigenden Flächen von Verschmutzungen befreit, sondern auch die Berührungsflächen der Leit-Schaufeln und der Kammer, also deren Innenwandung, abnutzt, ist es vorteilhaft, diese Teile auswechselbar auszubilden, wozu sich der vorstehend beschriebene hohlzylindrische Einsatz besonders eignet.
Da die Leit-Schaufeln selbstverständlich ganz besonders dem Verschleiß ausgesetzt sind und deshalb eher ersetzt werden müssen als der ringförmige Einsatz selbst, ist vorgesehen, daß die Leit-Schaufeln einzeln aus dem Einsatz heraus bzw. hineingesteckt werden können.
Durch diese Anordnung des Einsatzes innerhalb der Kammer der Strahldüse kann der Einsatz sehr einfach ausgetauscht bzw. auch die Leit-Schaufeln ausgewechselt werden, denn es genügt, wenn lediglich die Auslaßdüse von der Kammer gelöst wird, der Einsatz selbst kann dann ohne weiteres aus der Kammer herausgezogen werden.
Diese Leit-Einrichtungen haben den Vorteil, daß sie dem beim axialen Einlaß der Strahldüse eintretende Reinigungsmittel-Gemisch vor Eintritt in den Bereich der Leit-Schaufeln eine Vor-Rotation verleihen und dadurch die Beanspruchung der Leit-Schaufeln vermindern, d.h., deren Lebensdauer erhöhen.
Diese Ausbildung entspricht der Ausbildung des mit Leit-Schaufeln versehenen und oben bereits beschriebenen Einsatzes. Hierdurch ist es möglich, auch die einem Verschleiß unterliegenden Kanäle und Stege in einfacher Weise in der Kammer der Strahldüse auszuwechseln.
Durch diesen Einlaß kann beispielsweise Wasser dem durch den axialen Einlaß in die Kammer eintretenden Reinigungsmittel-Gemisch, das beispielsweise aus Luft und Granulat besteht, zugesetzt und damit unmittelbar an der Strahldüse ein entsprechendes Mischungsverhältnis hergestellt werden, wobei das Wasser-oder der Wasserdampf dem Trägermedium Luft eine höhere Dichte verleiht und das darin fein verteilte Granulat eine intensivere und höhere Rotationsgeschwindigkeit annimmt und die Intensität der Reinigungswirkung erheblich erhöht.
Durch diese Düse tritt infolge der dadurch bewirkten Entspannung des aus der Düse austretenden Wassers oder Wasserdampfes in der Vorkammer eine besonders feine Vernebelung des Wassers bzw. des Wasserdampfes ein, es wird in das Druckluft-Granulatgemisch dispergiert und erzielt somit eine höhere Dichte und das fein verteilte Granulat erhält dadurch eine höhere Rotationsgeschwindigkeit und intensiviert somit die Reinigungswirkung.
