Die erfindungsgemäße Strahlvorrichtung mit Strahlmittelrückführung gemäß unabhängigem Anspruch 1 weist einen Düsenhalter mit einer Spitze mit einer Modellierdüse auf, aus der das Strahlmittel in einem Druckstrahl auf ein zu bearbeitendes Objekt austritt. Der Düsenhalter ist beweglich in einer Schutzvorrichtung zum zu bearbeitenden Objekt hin angeordnet und weist eine zumindest teilweise offene Strahlhaube auf, wobei die Strahlhaube einen unteren Rand zum Aufsetzen auf das zu bearbeitende Objekt aufweist. Oberhalb des unteren Randes ist ein Lufteinlass sowie ein mit einer Absaugkammer verbundener Abzugsstutzen angeordnet, wobei die Absaugkammer gegenüberliegend zu dem Lufteinlass angeordnet ist. Der Düsenhalter ist beweglich oberhalb des unteren Randes angeordnet. Die Strahlhaube weist ein Sichtfenster sowie Eingriffsöffnungen mit Abdichtungsrosetten auf, die einen Durchgriff erlauben, oder mit Abdichtungshandschuhen, um den Düsenhalter mit der Modellierdüse an der Spitze händisch zu führen. Die Strahlhaube weist zudem eine Schlauchführung für einen von außerhalb der Strahlhaube ausgehenden Strahlmittelschlauch auf, wobei der Strahlmittelschlauch über die Führung in den Innenraum der Strahlhaube geführt ist.The blasting device according to the invention with blasting medium return according to
Die Verwendung einer Strahlhaube ermöglicht die Herstellung von Ornamenten und plastischen Verzierungen, ohne eine große Kabine zu benötigen. Derartige Kabinen sind sehr aufwendig und weisen einen entsprechenden Platzbedarf auf. Mit einer derartigen Strahlhaube versehen kann die Strahlvorrichtung einerseits eine ausreichende Rückführung von Strahlmittel und Abtrag ermöglichen als auch bei einer guten Platzierbarkeit eine ausreichende Abdichtung bereitstellen.The use of a jet hood allows the creation of ornaments and plastic decorations without the need for a large cabin. Such cabins are very expensive and require a corresponding amount of space. Provided with such a blasting hood, the blasting device can, on the one hand, enable sufficient return of blasting medium and abrasion and, with good placeability, provide a sufficient seal.
Der Düsenhalter am Sandstrahlschlauch kann innerhalb der Haube frei beweglich nach oben, nach unten und zu jeder Seite bewegt werden.The nozzle holder on the sandblasting hose can be moved freely upwards, downwards and to each side within the hood.
Durch das Sichtfenster ist es dem Benutzer möglich, den Düsenhalter mit der Modellierdüse bei der Bearbeitung optisch zu verfolgen. Das Sichtfenster kann zum unteren Rand beabstandet sein.The viewing window enables the user to optically follow the nozzle holder with the modeling nozzle during processing. The viewing window can be spaced from the lower edge.
Eingriffsöffnungen mit Abdichtungsrosetten oder Abdichtungshandschuhen haben den Vorteil, dass das Austreten von Strahlmittel bei dem händischen Führen verringert oder verhindert wird.Access openings with sealing rosettes or sealing gloves have the advantage that the escape of blasting media during manual handling is reduced or prevented.
Mit einer Schlauchführung ist das Nachführen oder Nachholen des Strahlmittelschlauchs zur Ausrichtung des Düsenhalters zum Werkstück erleichtert. Der Schlauch ist dabei ausreichend biegbar, um die Handhabung sicher zu ermöglichen. Der Schlauch kann auch über einen Faltenbalg gegenüber der Führung abgedichtet sein und dabei gleichzeitig längsbeweglich verschiebbar sein.A hose guide makes it easier to move or catch up with the abrasive hose to align the nozzle holder with the workpiece. The hose is sufficiently flexible to allow safe handling. The hose can also have a bellows opposite the guide be sealed and at the same time be longitudinally movable.
Vorteilhafterweise kann der Lufteinlass mindestens eine Öffnung in der Gehäusewand der Strahlhaube sein und kann die Öffnung mittels eines in einem Abstand zu dem Lufteinlass angeordneten Abschirmbleches gegenüber dem Innenraum der Haube abgedeckt sein, wobei das Abschirmblech in seiner Höhe gegenüber dem unteren Rand zurückversetzt ist, so dass sich bei auf das zu bearbeitende Objekt aufgesetzter Strahlhaube ein Spalt zwischen dem Abschirmblech und dem Objekt einstellt.The air inlet can advantageously be at least one opening in the housing wall of the jet hood and the opening can be covered by means of a shielding plate arranged at a distance from the air inlet relative to the interior of the hood, the shielding plate being set back in height relative to the lower edge, so that When the jet hood is placed on the object to be processed, a gap is created between the shielding plate and the object.
Auf diese Weise lässt sich ein gleichmäßiger Luftstrom über die gesamte Grundfläche der Strahlhaube hinweg bereitstellen.In this way, a uniform air flow can be provided over the entire base area of the jet hood.
Vorteilhafterweise weist der untere Rand eine dem Objekt zugewandte reibungsarme Beschichtung auf. Dadurch ist es möglich, die Strahlhaube mit verringertem Kraftaufwand auf der Oberfläche entlangzubewegen. Als Werkstoff kommt beispielsweise PTFE in Betracht, wobei eine Schichtdicke von weniger als 1 mm ausreichend sein kann.The lower edge advantageously has a low-friction coating facing the object. This makes it possible to move the jet hood along the surface with less effort. For example, PTFE comes into consideration as a material, with a layer thickness of less than 1 mm being sufficient.
Vorteilhafterweise kann der untere Rand eine Dichtung aus einem elastisch verformbaren Material aufweisen. Ein geeignetes Material hierfür ist beispielsweise ein Porengummi wie etwa Moosgummi.The lower edge can advantageously have a seal made of an elastically deformable material. A suitable material for this is, for example, a pore rubber such as foam rubber.
Vorteilhafterweise kann um den unteren Rand herum eine Bürstenleiste mit Borsten angeordnet sein, die insbesondere mindestens zwei Betriebszustände einnehmen kann, nämlich einerseits eine den unteren Rand seitlich und nach unten überragende Abdichtungsposition und eine neutrale Position, bei der die Borsten der Bürstenleiste oberhalb des unteren Randes liegen. So kann eine Beschädigung der Borsten bei dem Transport oder bei der Aufbewahrung der Strahlhaube vermieden werden.Advantageously, a brush strip with bristles can be arranged around the lower edge, which can in particular assume at least two operating states, namely on the one hand a sealing position protruding laterally and downward over the lower edge and a neutral position in which the bristles of the brush strip are above the lower edge . This can damage the bristles can be avoided during transport or storage of the jet hood.
Vorteilhafterweise kann sich die Strahlhaube vom unteren Rand weg nach oben, also zum Benutzer hin verjüngen und dabei insbesondere kegelförmig ausgebildet sein. Dadurch verbessert sich die Handhabbarkeit der Strahlhaube.Advantageously, the jet hood can taper away from the lower edge upwards, that is to say towards the user, and can in particular be conical in shape. This improves the handling of the jet hood.
Bei einer Schlauchführung kann vorzugsweise die Führung den Schlauch unter Ausbildung eines engen Spaltes, insbesondere kleiner als 1 mm umgeben und dabei eine Länge aufweisen, die mindestens dem Schlauchdurchmesser entspricht.In the case of a hose guide, the guide can preferably surround the hose with the formation of a narrow gap, in particular less than 1 mm, and thereby have a length which corresponds at least to the hose diameter.
Zur weiteren Verbesserung der Zuführung des Strahlmittelschlauchs kann an der Strahlhaube in einem Abstand zur Schlauchführung ein Führungsmittel für den Strahlmittelschlauch angeordnet sein, insbesondere eine Führungsrolle. Damit richtet sich der Strahlmittelschlauch auf eine reibungsarme und knickfreie Weise zur Führung in der Strahlhaube aus und es ist ein Längenausgleich möglich, wenn der Benutzer die Düse anders ausrichten möchte.To further improve the feeding of the blasting hose, a guide means for the blasting hose, in particular a guide roller, can be arranged on the blasting hood at a distance from the hose guide. In this way, the blasting agent hose aligns itself in a low-friction and kink-free manner for guidance in the blasting hood and length compensation is possible if the user wants to align the nozzle differently.
Vorteilhafterweise kann die Haube an ihrer Innenseite mit einer verschleißverminderten elastischen Beschichtung versehen sein. Da das im Innern der Strahlhaube verwendete Strahlmittel abrasive Wirkung aufweist, kann so die Lebensdauer verlängert werden. Auch das Sichtfenster und die Abdeckplatte für die Innenbeleuchtung kann eine verschleißmindernde Beschichtung aufweisen, die jedoch lichtdurchlässig ausgebildet sein muss.Advantageously, the inside of the hood can be provided with a wear-reduced elastic coating. Since the abrasive used inside the blasting hood has an abrasive effect, the service life can be extended. The viewing window and the cover plate for the interior lighting can also have a wear-reducing coating, which, however, must be transparent.

Eine derartige Strahlhaube kann als Schutzvorrichtung in einer Strahlvorrichtung eingesetzt werden.Such a jet hood can be used as a protective device in a jet device.
Vorteilhafterweise kann die Führung den Schlauch unter Ausbildung eines engen Spaltes, insbesondere < 1 mm, umgeben und vorzugsweise eine Länge aufweisen, die mindestens dem Schlauchdurchmesser entspricht. Damit ist eine gute Zuführung und eine ausreichende Abdichtung sichergestellt.The guide can advantageously surround the hose with the formation of a narrow gap, in particular <1 mm, and preferably have a length which corresponds at least to the hose diameter. This ensures good feed and adequate sealing.
Vorteilhafterweise kann der Schlauch über einen Faltenbalg gegenüber der Führung abgedichtet sein und dabei gleichzeitig längsbeweglich verschiebbar sein.Advantageously, the hose can be sealed off from the guide by means of a bellows and at the same time can be displaced in a longitudinally movable manner.
Vorteilhafterweise kann die Absaugkammer ein Strömungsblech aufweisen, das in seiner Höhe gegenüber dem unteren Rand zurückversetzt ist und einen Spalt zum Objekt aufweist. Dadurch wird ein über die Breite der Absaugkammer gleichmäßiger Ansaugquerschnitt bereitgestellt.The suction chamber can advantageously have a flow plate which is set back in height relative to the lower edge and has a gap to the object. This provides a suction cross-section that is uniform over the width of the suction chamber.
Vorteilhafterweise kann der Strömungsquerschnitt der Absaugkammer zum Abzugsstutzen hin zunehmen, sodass über die gesamte Länge der Absaugkammer ausreichend Raum für die angesaugte Luft zur Verfügung steht.Advantageously, the flow cross-section of the suction chamber can increase towards the extraction nozzle, so that sufficient space is available for the sucked-in air over the entire length of the suction chamber.
Die erfindungsgemäße Strahlhaube kann kegelförmig aufgebaut sein und entweder eckig oder rund sein. Ein Sichtfenster an der Spitze der Strahlhaube ermöglicht einen Blick auf die Modellierdüse, wobei das Sichtfenster leicht auswechselbar ist, um im Falle der Eintrübung der Sicht durch Verschleiß ausgetauscht zu werden.The jet hood according to the invention can be conical and either angular or round. A viewing window The tip of the jet hood allows a view of the modeling nozzle, the viewing window being easily exchangeable so that it can be exchanged in the event that the view is clouded due to wear and tear.
Die Bedienung der Strahlvorrichtung erfolgt entweder über Fuß- oder Handtaster, welcher mit dem Strahlgerät zusammenwirkt und die Bereitstellung des Strahlmittels einerseits wie auch die Strahlmittelrückgewinnung andererseits ein- und ausschaltet.The blasting device is operated either via a foot or hand switch, which interacts with the blasting device and switches the provision of the blasting agent on and off on the one hand and the blasting medium recovery on the other.

Wenn die Düse senkrecht zur Steinoberfläche gehalten ist, dann tritt der Strahl senkrecht zur Oberfläche aus und trägt Material aus der Oberfläche unterhalb des Strahles ab. In diesem Falle ist der Sandstrahlschlauch 15, der im Wesentlichen mittig in die Strahlhaube 1 eingeführt wird, ziemlich gerade und in der Regel kurz, es sei denn, man strahlt in der Strahlhaube in einem deutlichen Abstand zu der Führung 14.If the nozzle is held perpendicular to the stone surface, then the jet exits perpendicular to the surface and removes material from the surface below the jet. In this case, the sandblasting
Wenn die Düse vom Bediener weg geneigt wird, und zwar entgegen der Einführungsseite, dann muss der Sandstrahlschlauch 15 eine größere Schlaufe machen, weil er aufgrund der Steifigkeit mit einem leichten Radius zum Düsenhalter hin zugeht und nicht abgewinkelt ist. In diesem Fall wird mehr Schlauchlänge im Innern der Strahlhaube 1 benötigt und in diesem Winkel kann man dann auch Hinterschneidungen wie Rosenblätter bzw. Rosenknospen, die ja nach unten wieder rund zulaufen, einbringen. Der Winkel der Führung 14 selbst ist nur soweit von Bedeutung, dass die Düse im entsprechenden Winkel gehalten werden kann und dass dazu der Platz vorhanden ist und dass die Schlauchlänge variabel zugeführt und auch wieder herausgeführt werden kann.If the nozzle is tilted away from the operator, specifically against the insertion side, then the sandblasting
