Vorrichtung zur Innenreinigung eines BetonmischersDevice for cleaning the inside of a concrete mixer
Die Erfindung betrifft eine Vorrichtung zur Innenreinigung eines Betonmischers.The invention relates to a device for interior cleaning a cement mixer.
Bekanntlich stellt die Innenreinigung von Betonmischern ein erhebliches Problem für die Benutzer dar. Die Benutzer müssen mindestens einmal täglich die an den Schaufeln und den Wänden des Mischers anhaftenden Betonrückstände entfernen. Dies geschieht mit Hilfe von Meißeln und Hämmern, insbesondere wenn bereits ein Abbinden des Betons stattgefunden hat. Häufig führen diese Reinigungsmaßnahmen zu einer Beschädigung der Mischer. As is well known, the interior cleaning of concrete mixers poses a significant problem for users. The users must remove the concrete residue adhering to the blades and walls of the mixer at least once a day remove. This is done with the help of chisels and hammers, especially if the Concrete has taken place. These cleaning measures often damage the mixer.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der gattungsgemäßen Art zu schaffen, die eine ständige Säuberung des Innenraums von Betonmischern unter Vermeidung von Betonablagerungen an beweglichen oder feststehenden Teilen ermöglicht.The invention is therefore based on the object of creating a device of the generic type that has a constant cleaning of the interior of concrete mixers avoiding concrete deposits on moving ones or fixed parts.
Diese Aufgabe wird erfindungsgemäß bei einer Vorrichtung der gattungsgemäßen Art durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Die Ausrichtung der Wasserspritzdüsen ist derart, daß mit ihrem Wasserstrahl der gesamte Innenraum des Betonmischers ausgespült wird.According to the invention, this object is achieved with a device of the generic type solved by the characterizing features of claim 1. The orientation of the water spray nozzles is such that the entire interior of the concrete mixer is flushed out with its water jet.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen anhand der Zeichnung. Es zeigtFurther features and advantages of the invention emerge from the following description of exemplary embodiments based on the drawing. It shows
Fig. 1 einen als liegenden Trommelmischer ausgebildeten Betonmischer mit einer Vorrichtung nach der Erfindung undFig. 1 is a concrete mixer designed as a horizontal drum mixer with a device according to the Invention and
Fig. 2 einen stehenden Betonmischer mit einer Vorrichtung nach der Erfindung.2 shows a standing concrete mixer with a device according to the invention.
In den Ausführungsbeispielen sind Wasserspritzdüsen 1 in Reihe miteinander und über eine Leitung 2 mit einer Pumpe 3 zur Zuführung des Wassers unter erhöhtem Druck verbunden. Die Pumpe 3 ist mit einem Druckregler ausgerüstet, der eine Einstellung des Wasserdruckes zwischen 1o und 15o at je nach Erfordernis ermöglicht. Die Düsen sind entsprechend der Ein- und Auslaßöffnung eines Betonmischers angeordnet. Sie können geradlinig angeordnet sein, wie dies in Fig. 1 gezeigt und bei als liegender Trommelmischer 4 mit auf einer horizontalen Achse drehenden Schaufeln 5 ausgebildeten Betonmischern der Fall ist. Ebenfalls möglich ist eine kreisförmige Anordnung der Düsen 1, wie in Fig. 2 gezeigt. Diese Anordnung findet Anwendung bei stehenden Betonmischern 6 mit auf einer vertikalen Achse drehenden Schaufeln 7. Die Ausrichtung der Düsen 1 ist derart,daß der jeweilige Wasserstrahl den gesamten Innenraum des Mischers ausspült und insbesondere jene Bereiche, in welchen die meisten Betonrückstände abgelagert werden.In the exemplary embodiments, water spray nozzles 1 are in series with one another and via a line 2 with a Pump 3 connected to supply the water under increased pressure. The pump 3 is equipped with a pressure regulator, which enables the water pressure to be set between 1o and 15o at, depending on requirements. The nozzles are arranged according to the inlet and outlet openings of a concrete mixer. They can be arranged in a straight line be, as shown in Fig. 1 and when a horizontal drum mixer 4 with rotating on a horizontal axis Shovels 5 trained concrete mixers is the case. A circular arrangement is also possible of the nozzles 1 as shown in FIG. This arrangement is used with upright concrete mixers 6 a vertical axis rotating blades 7. The orientation of the nozzles 1 is such that the respective water jet flushes out the entire interior of the mixer and especially those areas in which most of the concrete residue is be deposited.
Die Wasserspritzdüsen 1 sind jeweils bei den beiden dargestellten Betonmischern im Bereich des Randes der jeweiligen Ein- und Auslaßöffnung lösbar angebracht.The water spray nozzles 1 are each in the two concrete mixers shown in the area of the edge of the respective inlet and outlet openings detachably attached.

Der jeweilige Reinigungszyklus der Mischer kann im Anschluß an einen jeden Mischvorgang oder im Wechsel zwischen den Vorgängen erfolgen. Das am Boden des Mischers gesammelte Wasser kann für die nachfolgende Mischung verwendet werden. Eine Zugabe von Zusatzstoffen, die mit dem Beton vereinbar sind, in das Wasser ist möglich.The respective cleaning cycle of the mixer can follow each mixing process or alternate between the operations take place. The water collected at the bottom of the mixer can be used for the subsequent mixing will. It is possible to add additives to the water that are compatible with the concrete.
Ein zufriedenstellendes Reinigungsergebnis für Mischer mittlerer Größenordnung kann mit ca. 1o Liter Wasser, versprüht in einem Zeitraum von ca. 1o Sekunden, erreicht werden.A satisfactory cleaning result for mixers of medium size can be achieved with approx. 10 liters of water, sprayed in a period of about 10 seconds, achieved will.
