Abstract
Description
Die Neuerung betrifft eine Saugvorrichtung nach dem Oberbegriff des Anspruches 1.The innovation concerns a suction device after the preamble of claim 1.
Aufgabe der Neuerung ist, eine Saugvorrichtung mit Injektorwirkung vorzuschlagen, mit der eine extrem hohe Sauggeschwindigkeit erzielt werden kann, und mit der der Anstellwinkel der Saugströmung einstellbar ist.The task of the innovation is a suction device to propose with injector effect, with an extremely high suction speed can be achieved, and with which the angle of attack of the suction flow can be adjusted is.
Gemäß der Neuerung wird diese Aufgabe mit einer gattungsgemäßen Saugvorrichtung gelöst, bei der das Saugrohr auf der Einlassseite Injektordüsen aufweist, die mit einem von einer Druckluftquelle erzeugten Druckluftstrom gespeist werden, der von den Düsen in einem vom abzusaugenden Material abhängigen Anstellwinkel mit hoher Geschwindigkeit in das Saugrohr eintritt.According to the innovation, this task is done with a generic suction device solved at which has the suction pipe on the inlet side injector nozzles that are connected to a compressed air flow generated by a compressed air source is fed, that of the nozzles with a high angle of attack depending on the material to be extracted Speed enters the intake manifold.
Die Injektordüsen sind vorzugsweise in einem Düsenring angeordnet, der von einem Außenring umgeben ist. Der Außenring nimmt das Druckrohr auf, über das komprimierte Luft durch die Injektordüsen hindurch in das Saugrohr eingeführt werden. Außenring und Düsenring sind dabei miteinander verspannt, so dass der Luftstrom durch die Einlassöffnung des Druckrohres ausschließlich über die Injektordüsen in das Saugrohr einströmen kann. Durch die komprimierte Druckluft im Druckrohr und das hohe Querschnittsverhältnis zwischen dem Drucklufteintritt und dem Querschnitt der Düsen wird eine extrem hohe Austrittsgeschwindigkeit an den Düsenauslässen in das Saugrohr erzielt. Die Anordnung der Düsen im Düsenring ist so gewählt, dass die Luft, die mit hoher Geschwindigkeit aus den Düsen austritt, in einem geringen Winkel zur Saugrohrwandung austritt, so dass im Eintrittsbereich des Saugrohres zum Ansaugen des aufzunehmenden Materials ein hoher Unterdruck im Bereich des Düsenringes entsteht, der mit zunehmendem Abstand in Längsrichtung des Rohres in einen Überdruck gegen den Atmosphärendruck übergeht, der das abzusaugende Material wegdrückt.The injector nozzles are preferably in one nozzle ring arranged by an outer ring is surrounded. The outer ring takes the pressure pipe on the compressed air through the injector nozzles into the intake manifold introduced become. outer ring and nozzle ring are clamped together so that the air flow through the inlet port of the pressure pipe only via the injector nozzles into the Intake intake manifold can. Due to the compressed air in the pressure pipe and the high Aspect ratio between the compressed air inlet and the cross section of the nozzles extremely high exit velocity achieved at the nozzle outlets in the intake manifold. The arrangement of the nozzles in the nozzle ring is chosen that the air that comes out of the nozzles at high speed emerges at a small angle to the intake manifold wall, so that in the Entry area of the suction pipe for sucking in the material to be picked up A high negative pressure is created in the area of the nozzle ring increasing distance in the longitudinal direction of the pipe into overpressure goes against atmospheric pressure, that pushes away the material to be extracted.
Durch die neuerungsgemäße Ausgestaltung der ringförmig angeordneten Vielzahl von Düsen werden die austretenden Strahlen mit vielfacher Geschwindigkeit der Luftströmung im Druckrohr in das Saugrohr eingeleitet und ergeben am Auslassende des Ringes eine extrem hohe Saugwirkung.Due to the new design of the annular arranged variety of nozzles the emerging rays are at multiple speeds the air flow introduced in the pressure pipe in the suction pipe and result at the outlet end of the Ring has an extremely high suction effect.
Auf der Ansaugseite der Saugvorrichtung ist am Düsenring und/oder am Außenring ein Werkzeug, z.B. eine Fräse, ein Besen oder dergl. ansetzbar, um die Saugvorrichtung als Flüssigkeits- oder Staubsauger betreiben zu können, wobei die Ausgestaltung des Werkzeuges in beliebiger Weise variiert werden kann, damit das Absaugen verschiedenster Materialien vorgenommen werden kann. Die Verbindung zwischen einem derartigen Werkzeug und der Einlassseite der Saugvorrichtung kann z.B. durch Steck- oder Schraubverbindung oder durch Schnellverschluss vorgenommen werden. Durch Änderung des Anstellwinkels der Düsen innerhalb des Düsenringes wird eine gezielte Anpassung an das jeweils abzusaugende Material erreicht. Die Änderung des Anstellwinkels kann einerseits dadurch erzielt werden, dass die Düsen so ausgelegt sind, dass sie in begrenztem Umfang variabel anstellbar sind, oder aber dadurch, daß der Düsenring durch einen anderen Düsenring mit unterschiedlichem Anstellwinkel der Düsen ersetzt wird.On the suction side of the suction device is on the nozzle ring and / or on the outer ring a tool, e.g. a milling machine, a broom or the like. attachable to the suction device as a liquid or to be able to operate a vacuum cleaner the design of the tool varies in any way can be done so that the extraction of various materials can be. The connection between such a tool and the inlet side of the suction device can e.g. by plug or screw connection or be done by quick release. By change the angle of attack of the nozzles inside the nozzle ring targeted adaptation to the material to be extracted. The change of the angle of attack can be achieved on the one hand in that the nozzles are designed so that they can be variably adjusted to a limited extent are, or in that the nozzle ring through another nozzle ring with a different angle of attack of the nozzles.
Nachstehend wird die Neuerung in Verbindung mit der Zeichnung anhand eines Ausführungsbeispieles erläutert. Es zeigt:The innovation in Connection with the drawing explained using an exemplary embodiment. It shows:
