Abstract
Reinigungsdüse zum Reinigen von Rohren und Kanälen, bestehend aus einem Düsenkörper (2), einem darin drehbar gelagerten Düsenkopf (1) mit Auslassdüsen (13) und einer Wasserzuführung (3) zum Zuleiten von Wasser über Bohrungen (12, 13, 15) zum Düsenkopf (1) und zu den Auslassdüsen (13), dadurch gekennzeichnet, dass am Düsenkörper (2) eine Pralleinrichtung (16) im Abstand (25) zu den Auslassdüsen (13) angeordnet ist, bestehend aus einer umlaufenden Mantelfläche (17) mit Nuten (19), und dass einige oder alle Auslassdüsen (13) so gerichtet sind, dass ein Teil des ausgestoßenen Wasserstrahls (21) unter einem Auftreffwinkel (22) zwischen 0,5° und 30° gegen die Seitenwand der Nuten (19) strahlt.Cleaning nozzle for cleaning pipes and channels, consisting of a nozzle body (2), a nozzle head (1) rotatably mounted therein with outlet nozzles (13) and a water supply (3) for supplying water via bores (12, 13, 15) to the nozzle head (1) and to the outlet nozzles (13), characterized in that on the nozzle body (2) a baffle means (16) at a distance (25) to the outlet nozzles (13) is arranged, consisting of a circumferential lateral surface (17) with grooves ( 19), and that some or all of the outlet nozzles (13) are directed so that part of the ejected water jet (21) radiates at an angle of incidence (22) between 0.5 ° and 30 ° against the side wall of the grooves (19).
Description
Die Erfindung betrifft eine Reinigungsdüse zum Reinigen von Kanälen oder Rohren, insbesondere in der Abwassertechnik, mit den Merkmalen des Oberbegriffs des Anspruches 1.The invention relates to a cleaning nozzle for cleaning channels or pipes, in particular in wastewater engineering, having the features of the preamble of
Aus der
Bei Reinigungsdüsen dieser Bauart – also versehen mit einer mechanischen Bremse – besteht das Problem, dass wechselnder Wasserdruck und unterschiedliche Reibungsverhältnisse der Wellendichtringe (z. b. Anlaufzustand und Betriebszustand, Toleranzen in der Fertigung) zu einer unkontrollierten, im Betrieb wechselnden Drehzahl des Düsenkopfes führen. Wegen den engen Baumaßen ist zudem kein großes Bremsmoment der Bremse erzielbar. Die heute eingesetzten Bremsscheiben aus Keramik sind zudem relativ teuer.In cleaning nozzles of this type - that is provided with a mechanical brake - there is the problem that changing water pressure and different friction conditions of the shaft seals (eg., Start-up state and operating state, manufacturing tolerances) lead to an uncontrolled, changing in operation speed of the nozzle head. Because of the tight dimensions also no great braking torque of the brake can be achieved. The ceramic discs used today are also relatively expensive.
Der Erfindung liegt die Aufgabe zugrunde, die geschilderten Nachteile des Standes der Technik zu vermeiden und eine Bremswirkung des Düsenkopfes zu erreichen ohne den Einsatz einer verschleißanfälligen mechanischen Bremse. Die Drehzahl des Düsenkopfes sollte ohne verschleißanfällige Bauteile bei einem bestimmten Wasserdruck und damit bei einer entsprechenden Ausströmgeschwindigkeit des Wassers im Betriebszustand konstant bleiben und keine zu hohe und ungewünschte Drehzahl annehmen.The invention has for its object to avoid the disadvantages of the prior art and to achieve a braking effect of the nozzle head without the use of a wear-prone mechanical brake. The speed of the nozzle head should remain constant without susceptible components at a certain water pressure and thus at a corresponding outflow velocity of the water in the operating state and assume too high and unwanted speed.
Gelöst ist diese Aufgabe erfindungsgemäß durch die im Kennzeichen des Hauptanspruchs angegebenen Maßnahmen. Bevorzugte Weiterbildungen des Erfindungsgegenstandes ergeben sich aus den übrigen, in den Unteransprüchen genannten Merkmalen.This object is achieved according to the invention by the measures indicated in the characterizing part of the main claim. Preferred developments of the subject invention will become apparent from the remaining, mentioned in the dependent claims characteristics.
Die Erfindung ist anhand der schematischen Zeichnungen
Wenn die Reinigungsdüse für Rohre und Kanäle mit größerem Querschnitt verwendet werden soll wird sie an einem – nicht dargestellten – Führungsschlitten mittig befestigt.If the cleaning nozzle is to be used for pipes and channels with a larger cross section, it is attached to a - not shown - guide carriage centered.
