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.

Abstract
Description
Die Erfindung bezieht sich auf eine zum Einsatz bei Vorrichtungen zur Reinigung von insbesondere Stein- und/oder Metallflächen vorgesehene Strahldüse mit einer rotationssymetrischen Kammer, die einen axialen Einlaß für ein Reinigungsmittel-Gemisch und einen axialen Auslaß mit einer sich daran anschließenden Auslaßdüse für das Reinigungsmittel-Gemisch aufweist, wobei die rotationssymetrische Kammer an ihrer Innenwandung ausgebildete Leit-Einrichtungen zur Beinflussung der Strömung des Reinigungsmittel-Gemisches aufweist, die nach Art von in den Innenraum der Kammer einstehenden Leit-Schaufeln ausgebildet sind, die mit ihren Flächen gegenüber der Längsachse der Kammer verstellt sind.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.
Eine solche Strahldüse ist aus der deutschen Patentschrift Nr. 206 610 bekannt. Die darin beschriebene Strahldüse ist insbesondere zum Einsatz als Sandstrahlblasdüse vorgesehen, bei welcher die Leit-Einrichtungen als schraubenförmig verlaufende Erhöhungen bzw. Vertiefungen, z.B. als in die Innenwandung eingeschnittene Rillen ausgebildet sind. Die aus Erhöhungen, Rippen oder Rillen gebildeten Züge stoßen dabei unmittelbar aneinander, so daß zwischen ihnen keine zylindrischen Mantelflächen stehenbleiben.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.
Infolge dieser Ausbildung der Innenwandung der Kammer der Strahldüse wird das durch den axialen Einlaß eingeführte Reinigungsmittel-Gemisch in eine schraubenförmige Bewegung bzw. Drehung gebracht und tritt dann aus dem axialen Auslaß und der Auslaßdüse auf die zu reinigende Fläche, wobei aber wegen der Rotation vermieden wird, daß der Reinigungsmittel-Gemisch-Strahl lotrecht auftrifft, vielmehr annähernd tangential über die zu reinigende Fläche hinweggeführt wird und wodurch die in dem Reinigungsmittel-Gemisch enthaltenen festen Partikel, bei der bekannten Strahldüse eben der hindurchgeführte Sand, eine besonders gute säubernde, nämlich "wischende" Wirkung entfalten können.As a result of this design of the inner wall of the chamber of the jet nozzle, 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.
Aber unabhängig davon, wie nun die Züge in der Innenwandung der Kammer der Strahldüse ausgebildet sind, wird der durch die Strahldüse hindurchgeleitete Reinigungsmittel-Gemisch-Strom nicht vollständig über seinen gesamten Strömungsquerschnitt in die gewünschte schraubenförmige Rotationsbewegung versetzt. Wegen der verhältnismäßig großen Strömungsgeschwindigkeit und der verhältnismäßig geringen Länge einer solchen Strahldüse bleibt ein nicht rotierender, sondern nur linear fortschreitender Kernbereich in dem Reinigungsmittel-Gemisch-Strom bestehen. Dies bedeutet, daß ein Teil des Reinigungsmittel-Gemisches, insbesondere die darin enthaltenen Partikel, direkt auf die zu reinigenden Flächen aufprallt.But regardless of how the trains are designed in the inner wall of the chamber of the jet nozzle, 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.
In der DE-PS 37 18 971 wird ein weiterer Weg aufgezeigt, das Reinigungsmittel-Gemisch in eine schraubenförmige Bewegung bzw. Drehung zu versetzen, nämlich dadurch, daß die Leit-Einrichtungen nach Art von in den Innenraum der Kammer einstehenden Drallflügeln ausgebildet sind, die mit ihren Flächen gegenüber der Längsachse der Kammer verstellt sind. Diese Drallflügel sind zudem noch in einem als Ring gestalteten Einsatzkörper vorgesehen, der unmittelbar vor der konisch ausgebildeten Auslaßdüse angeordnet und mit seinen Innenwandungen dieser konischen Ausbildung der Auslaßdüse angepaßt ist. Dies bedeutet, daß sich die Drallflügel auf den konisch ausgebildeten Innenflächen des Einsatzkörpers befinden, wodurch die Ausbildung des Einsatzkörpers mit den Drallflügeln technisch sehr aufwendig und damit auch teuer ist. Gerade die Drallflügel nutzen sich durch das an ihnen vorbeigleitende und von ihnen in eine Rotation versetzte Reinigungsmittel-Gemisch sehr schnell ab und dieser Einsatzkörper ist deshalb häufig zu erneuern. Aber auch bei dieser bekannten Ausführungsform bleibt ein nicht rotierender, sondern nur linear fortschreitender Kernbereich in dem Reinigungsmittel-Gemisch-Strom bestehen, denn die Drallflügel reichen nicht bis zum Mittelpunkt des Querschnittes der Strahldüse heran, wäre dies der Fall, würden die Drallflügel einer noch größeren Abnützung unterliegen.In DE-PS 37 18 971 another way is shown to set the detergent mixture in a helical movement or rotation, namely in that the guide devices are designed in the manner of swirl vanes protruding into the interior of the chamber, which are adjusted with their surfaces in relation to the longitudinal axis of the chamber. These swirl vanes are also provided in an insert body designed as a ring, which is arranged directly in front of the conical outlet nozzle and with its inner walls is adapted to this conical configuration of the outlet nozzle. This means that the swirl vanes are located on the conically shaped inner surfaces of the insert body, which means that the formation of the insert body with the swirl vanes is technically very complex and therefore also expensive. 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.
Um nun aber eine vollständige Rotation des gesamten Querschnittes des Reinigungsmittel-Gemisch-Stromes zu erreichen, ist man dazu übergegangen, einen Teil des Gesamt-Reinigungsmittel-Gemisches, beispielsweise das Luft-Granulat-Gemisch, dem axial eintretenden Wasser erst später hinzuzuführen, nämlich im Bereich der Kammer der Strahldüse. Dazu wurde eine entsprechende Einlaßdüse seitlich an der Strahldüse in einem Winkel zur Längsachse der Düse, beispielsweise 15 bis 30° vorgesehen, durch die das Luft-Granulat-Gemisch in die Kammer eintritt. Damit nun dieser eintretende Gemischstrahl das am Einlaßende der Kammer axial eingeführte Wasser und damit auch das Gesamt-Gemisch in die gewünschte schraubenförmige Rotationsbewegung zu versetzen, wurde der seitliche Einlaß für das Luft-Granulat-Gemisch exentrisch bzw. versetzt zur Längsachse der Kammer in diese eingeführt, so daß eine rotierende Verwirbelung stattfindet.However, in order to achieve a complete rotation of the entire cross-section of the detergent mixture flow, 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. For this purpose, 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. So that this incoming mixture jet, the axially introduced water at the inlet end of the chamber and thus also the entire mixture in the desired helical rotational movement, the lateral inlet for the air-granulate mixture was introduced eccentrically or offset to the longitudinal axis of the chamber , so that a rotating swirl takes place.
Eine solche Strahldüse ist in der EP 0 171 448 beschrieben. Nachteilig bei solchen Düsen ist, daß durch die exentrische Einführung eines Teils des Gesamt-Gemisches, und zwar gerade des Luft-/Granulat-Gemisches, dieses auf die der Eintrittsstelle gegenüberliegende Wandung der Kammer auftrifft und dieser Teil der Kammer einem extrem hohen Verschleiß unterliegt. Um einen solchen Verschleiß zu verhindern bzw. zumindest abzumindern wird beispielsweise in der DE-PS 40 02 787 eine Strahldüse beschrieben, die an den vor dem Verschleiß zu schützenden Stellen besondere Materialeinsätze aufweist.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. In order to prevent or at least reduce such wear, for example, DE-PS 40 02 787 describes a jet nozzle which has special material inserts at the points to be protected from wear.
Ausgehend von diesem bekannten Stand der Technik liegt nun der Erfindung die Aufgabe zugrunde, eine Strahldüse so auszubilden, daß sie einer gleichmäßigen Abnutzung unterworfen ist und insbesondere einen solchen Reinigungsmittel-Gemisch-Strom ausbildet, der über seinen gesamten Querschnitt schraubenförmig rotiert, wobei die Rotation frei eingestellt und damit auch die Abnutzung der Leit-Einrichtungen minimiert werden kann.Based on this known prior art, 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.
Dies wird bei einer gattungsgemäßen Strahldüse dadurch erreicht, daß die Leit-Schaufeln in ihrer radialen Höhe bis an die Längsachse der Kammer reichen und verstellbar ausgebildet sind.This is achieved with a generic jet nozzle in that the guide vanes extend radially up to the longitudinal axis of the chamber and are designed to be adjustable.
Durch diese längenmäßige Ausbildung der Leit-Schaufeln wird gewährleistet, daß der Reinigungsmittel-Gemisch-Strom über seinen gesamten Querschnitt in eine schraubenförmige Rotation überführt wird und nicht etwa, wie oben bei der Schilderung des Standes der Technik ausführlich beschrieben, ein gradlinig strömender Kern des Reinigungsmittel-Gemisches erhalten bleibt, der beim Auftreffen auf die zu reinigenden Flächen zerstörend wirken kann. Die Verstellbarkeit der Leit-Schaufeln erlaubt es zusätzlich, die grundsätzlich gewünschte Rotation unterschiedlich stark einzustellen, und zwar ohne weiteres während des Reinigungsvorganges. Hierdurch wird die erfindungsgemäße Strahldüse einsatz-flexibler, denn die Reinigung von unterschiedlichen Oberflächen wie beispielsweise Naturstein, Holz, Metalle, Kunststoffe, Gemälde, Fresken etc. verlangen aufgrund ihrer spezifischen Material- und/oder Struktureigenschaften eine Strahltechnik, die es ermöglicht, sich den stets ändernden Oberflächenbedingungen kontinuierlich anzupassen.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.
So ist zum Beispiel das Material Naturstein von Haus aus äußerst inhomogen, insbesondere hinsichtlich seiner Härte, und auch dessen Verwitterung durch Umwelteinflüsse ist am Objekt je nach Exposition unterschiedlich stark ausgeprägt. Das in Naturstein enthaltene Bindemittel Calziumcarbonat wandelt sich durch SO₂-Einwirkungen zu Calziumsulfat um und laugt das Bindemittel Calziumcarbonat unterschiedlich tief aus dem Steingefüge heraus und bildet an der Oberfläche eine mehr oder weniger dicke Gipskruste, wobei die dazwischenliegende Schicht von noch intaktem Naturstein bis hin zur Oberflächenkruste unterschiedliche Festigkeit aufweist. Gerade diese Inhomogenität erfordert eine Strahldüse, die es ermöglicht, den Wirkungsgrad während des Reinigungsprozesses diesen stets wechselnden Bedingungen anzupassen.
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.For example, 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.
In addition to the above-described advantageous adjustability of the cleaning agent mixture stream, 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.
Vorteilhaft sind die verstellbaren Leit-Schaufeln auf der Innenwandung eines hohlzylindrisch ausgebildeten Einsatzes angeordnet, der in die Kammer einsetzbar ist.
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.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.
In weiterer vorteilhafter Ausgestaltung sind die Leit-Schaufeln auswechselbar im Einsatz angeordnet.
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.In a further advantageous embodiment, 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.
Vorteilhaft ist der Einsatz benachbart zur Auslaßdüse angeordnet.
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.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.
In weiterer vorteilhafter Ausbildung der Erfindung sind zusätzlich zu den in den Innenraum der Kammer einstehenden Leit-Schaufeln auf der Innenseite der Kammer und, in Strömungsrichtung gesehen, vor den Leit-Schaufeln, Leit-Einrichtungen vorgesehen, die als an der Innenwandung der Kammer schraubenförmig verlaufende Kanäle und dazwischen liegende Stege ausgebildet sind.
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.In a further advantageous embodiment of the invention, in addition to the guide vanes protruding into the interior of the chamber, 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.
Vorteilhaft sind diese schraubenförmig verlaufenden Kanäle und Stege auf der Innenseite eines in die Kammer einsetz- bzw. einschiebbaren Einsatzes ausgebildet.
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.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.
Vorzugsweise weisen die Kanäle einen U-förmigen Querschnitt auf.The channels preferably have a U-shaped cross section.
Diese Ausbildung ist besonders gut dazu geeignet, dem Reinigungsmittel-Gemisch-Strom eine schraubenförmige Rotation aufzuprägen.This training is particularly well suited to impart a helical rotation to the detergent mixture flow.
In bevorzugter Weiterbildung der Strahldüse ist nach deren axialen Einlaß eine Vorkammer vorgesehen, die einen radialen Einlaß aufweist.
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.In a preferred development of the jet nozzle, a prechamber is provided after its axial inlet, which has a radial inlet.
Through this inlet, for example, 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.
Bevorzugt mündet der radiale Einlaß in Form einer Düse in die Vorkammer. 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.The radial inlet preferably opens into the prechamber in the form of a nozzle. As a result of the relaxation of the water or water vapor emerging from the nozzle in the prechamber, 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.

Die in Fig. 1 dargestellte Strahldüse 1 besteht im wesentlichen aus einer das zentrale Bauteil bildenden und rotationssymetrisch und hohlzylindrisch ausgebildeten Kammer 2, die einen axialen Einlaß 3 und einen axialen Auslaß 4 für den hindurchzuführenden Reinigungsmittel-Gemisch-Strom aufweist.The
Im Bereich des axialen Einlasses 3 weist die Innenwandung 5 der Kammer 2 ein Innengewinde 6 auf, in welches ein in bekannter Weise ausgebildeter Schlauchbefestigungsstutzen 7 eingeschraubt und gegenüber der Kammer 2 mittels eines O-Ringes 8 abgedichtet ist.In the area of the
Am axialen Auslaß 4 der Kammer 2 ist eine in Fig. 3 dargestellte Auslaßdüse 9 vorgesehen, die mittels einer Überwurfmutter 10, die ein Innengewinde 11 aufweist, auf die ein Aussengewinde 12 aufweisende Aussenwandung 13 des axialen Auslasses 4 aufgeschraubt ist.At the
Die Auslaßdüse 9 weist eine konische Ausbildung insbesondere der Innenwandung 14 auf, und zwar mit einem sich zum Öffnungsende 15 der Auslaßdüse 9 hin verjüngenden Durchmesser.The
In dem hohlzylindrisch ausgebildeten Innenraum der in Fig. 2 dargestellten Kammer 2 ist unmittelbar benachbart zu dem Einlaßende 16 der Auslaßdüse 9 ein in Fig. 4a und 4b abgebildeter Einsatz 17 vorgesehen, der ebenfalls eine hohlzylindrische Ausbildung mit einem Aussendurchmesser aufweist, der dem Durchmesser des Innenraumes der Kammer 2 entspricht. Dieser Einsatz 17 wiederum ist mit Leit-Schaufeln 18 versehen, die gegenüber der Längsachse 19 der Strahldüse anstellbar sind und dem durch die Strahldüse hindurchströmenden Reinigungsmittel-Gemisch eine schraubenförmige Rotation aufprägen können. Die gegen das durchströmende Reinigungsmittel-Gemisch gerichteten Kanten 20 der Leit-Schaufeln 18 sind spitz ausgeformt, um dem anströmenden Reinigungsmittel-Gemisch einen geringeren Widerstand entgegenzusetzen. Die rückwärtigen Kanten 21 der Leit-Schaufeln 18 sind dagegen in einfacher Weise abgerundet ausgebildet. Hierzu wird auf die Fig. 4a verwiesen.In the hollow-cylindrical interior of the
Die verstellbaren Leit-Schaufeln 18 können mittels Betätigungshebel 23 über durch die Wandungen der Kammer 2 und des Einsatzes 17 hindurchgeführte Stifte 23' verdreht werden, wobei in der Innenwandung 22 des Einsatzes 17 Ausnehmungen 22' vorgesehen sind, in welchen die Leit-Schaufeln 18 verschwenkbar sind.The
Nicht dargestellt in den Figuren ist eine denkbare, die Betätigungshebel 23 verbindende Steuervorrichtung, so daß mit einem einzigen Handgriff sämtliche drei in den Figuren gezeigten Leit-Schaufeln 18 gleichzeitig um dasselbe Maß verstellt werden können.Not shown in the figures is a conceivable control device connecting the actuating levers 23, so that all three
Zusätzlich zu dem Einsatz 17 ist in der Kammer 2 ein weiterer Einsatz 24 vorgesehen, der sich unmittelbar an den Einsatz 17 anschließt, jedoch gegenüber diesem eine größere Länge aufweist.In addition to the
Dieser Einsatz 24 ist an seiner Innenwandung 25 mit Kanälen 26 versehen, die schraubenförmig verlaufen und einen U-förmigen Querschnitt aufweisen. Die Kanäle 26 sind nicht unmittelbar benachbart zueinander in der Innenwandung 25 des Einsatzes 24 angeordnet, sondern weisen einen Abstand voneinander auf. Dieser Abstand zwischen den Kanälen 26 wird durch Stege 27 gebildet.This
Der Einsatz 24 dient dazu, den hindurchgeführten Reinigungsmittel-Gemisch-Strom zumindest in seinen Aussenbereichen vor Hindurchleitung durch den Einsatz 17 in eine schraubenförmige Rotation zu versetzen, dadurch wird insbesondere erreicht, daß der Einsatz 17 mit den Leit-Schaufeln 18 weniger schnell abgenutzt wird. Die Anstellung der Kanäle 26 und Stege 27 zur Längsachse 19 der Strahldüse 1 entspricht dabei einer mittleren Anstellung der Leit-Schaufeln 15 im Einsatz 17.The
Auch dieser Einsatz 24 ist austauschbar ausgebildet und kann nach Abschrauben der Überwurfmutter 11 und nach Entfernung der Auslaßdüse 9 ohne weiteres aus dem Innenraum der Kammer 2 herausgezogen werden.This
Wie Fig. 1 und insbesondere auch Fig. 2 erkennen lassen, ist bei dem hier beschriebenen Ausführungsbeispiel der Strahldüse noch zusätzlich zu den Einsätzen 17 und 24 eine Vorkammer 28 vorgesehen, die sich unmittelbar an den axialen Einlaß 3 der Kammer 2 anschließt und bis an den Anfang des Einsatzes 24 mit den schraubenförmigen Kanälen 26 und Stegen 27 reicht. In diese Vorkammer 28 mündet ein radialer Anlaß 29, der ein Innengewinde 30 zum Anschluß einer nicht dargestellten Zuleitung aufweist. Durch diesen radialen Einlaß 29 kann beispielsweise Wasser in die Strahldüse 1 eingeleitet werden, wenn beispielweise aus besonderen Gründen das Wasser noch nicht dem durch den axialen Einlaß 3 eintretenden Gesamt-Reinigungsmittel-Gemisch beigefügt werden soll.As can be seen in FIG. 1 and in particular also in FIG. 2, in the exemplary embodiment of the jet nozzle described here a
So ist es beispielsweise vorteilhaft, durch die gesonderte Zuführung von Wasser im Bereich der Vorkammer 28 der Strahldüse 1 eine gute Vermischung des Gesamt-Reinigungsmittel-Gemisches herzustellen, dazu ist vorteilhaft eine Einspritzdüse 31 im radialen Einlaß 24 vorgesehen. Die durch diese Düse hervorgerufene Entspannung des eingeführten Wassers in der Vorkammer gewährleistet die Aufbereitung eines intensiven Reinigungsmittel-Gemisches in Form einer das Reinigungsmittel (Substrat) enthaltenden Dispersion.For example, it is advantageous to produce a good mixture of the total cleaning agent mixture by the separate supply of water in the area of the
Aufgrund der vorbeschriebenen besonderen Ausgestaltung des Innenraumes der Kammer 2 dieser Strahldüse 1 kann ein Reinigungsmittel-Gemisch-Strahl ausgebildet werden, der über seinen gesamten Querschnitt eine schraubenförmige Rotationsbewegung ausführt und folglich eine hervorragende Reinigungswirkung auf die zu reinigenden Oberflächen ausübt, wobei die Intensität der Rotation einstellbar und damit die Reinigungswirkung der Düse dosierbar ist.Due to the above-described special design of the interior of the
Die erfindungsgemäße Strahldüse kann im Niederdruck- wie auch im Hochdruckbereich eingesetzt werden und eignet sich nicht nur zur Reinigung von Stein- und Metalloberflächen, sondern wegen ihrer variablen Einsetzbarkeit auch zur Reinigung von Holz- und Kunststoffoberflächen.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.
