Description

Schlammsauger Silt

Die vorliegende Erfindung betrifft einen Schlammsauger gemäß Oberbegriff von Anspruch 1.The present invention relates to a sludge sucker according to the preamble of claim 1.

Ein solcher Schlammsauger hat den Nachteil, daß ein Motor mit einem Kugelventil verbunden ist. Das Kugelventil befindet sich in der Nähe der vorgesehen Füllstandsgrenze des Aufhahmbehälters. Bei zunehmender Füllung des Aufiiahmebehälters und Erreichen der Füllstandsgrenze wird das Kugelventil in eine Verschlußstellung gebracht, die bewirkt, daß der Motor hörbar schneller läuft. In Abhängigkeit von dieser akustischen Wahrnehmung muß der Benutzer den Motor manuell ausstellen, damit eine automatische Entleerung über das Ablaufelement erfolgen kann.Such a sludge sucker has the disadvantage that a motor is connected to a ball valve. The ball valve is located close to the level limit of the receptacle. With increasing filling of the receptacle and reaching the filling level limit, the ball valve is brought into a closed position, which causes the motor to run audibly faster. Depending on this acoustic perception, the user must manually turn off the engine so that an automatic drainage can take place via the drain element.

Eine solche Vorgehensweise kann dazu fuhren, daß die akustischen Veränderungen des Motors nicht oder nicht rechtzeitig wahrgenommen werden, so daß der Aufnahmebehälter überläuft oder aber der Motor Schaden nimmt.Such a procedure can lead to the acoustic changes of the engine not being perceived or not being noticed in time, so that the receptacle overflows or the engine is damaged.

Die Aufgabe der vorliegenden Erfindung ist daher, einen Schlammsauger zu schaffen, mit dem während eines Schlammabsaugvorgang eine vollautomatische Entleerung durchge- führt werden kann..The object of the present invention is therefore to create a sludge sucker with which fully automatic emptying can be carried out during a sludge suction process.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1.

Der erfindungsgemäße Schlammsauger hat den Vorteil, das der Motor nicht mehr manuell in Abhängigkeit einer akustischen Veränderung abgeschaltet werden muß. Vielmehr schaltet sich der Motor nun automatisch ab, so daß eine Entleerung automatisch beginnen kann.The sludge extractor according to the invention has the advantage that the motor no longer has to be switched off manually as a function of an acoustic change. Rather, the engine now switches off automatically so that emptying can begin automatically.

Ferner kann das Gerät in einfacher Weise auch als herkömmlicher Naßsauger umgerüstet werden.Furthermore, the device can also be converted into a conventional wet vacuum in a simple manner.

Eine Ausführungsform der vorliegenden Erfindung wird im folgenden anhand der Zeichnungen näher beschrieben. Es zeigen: oasl015b Fig. 1 eine schematische Ansicht eines Schlammsaugers der vorliegenden Erfindung; Fig. 2 eine schematische Ansicht einer elektrischen Schaltung des erfindungsge- mäßen Schlammsaugers.An embodiment of the present invention is described below with reference to the drawings. It shows: oasl015b 1 is a schematic view of a sludge sucker of the present invention; 2 shows a schematic view of an electrical circuit of the sludge extractor according to the invention.

Ein erfindungsgemäßer Schlammsauger 1 umfaßt ein Gehäuse 1.1, an welchem ein Anschluß 1.2 für ein Saugelement 3 und ein Anschluß 1.3 für ein Abflußelement 5 ausgebildet ist. Das Gehäuse 1.1 ist zudem in seinem bodenfernen, oberen Bereich als ein Deckel 1.4 ausgebildet, der an dem unteren Gehäuse 1.1 lösbar befestigt ist. Bodenseitig ist das Gehäuse 1.1 mit einem Fußelement 1.5 versehen. Das Innere des Gehäuses 1.1 ist in seinem mittleren Bereich als Aufnahmebehälter 1.6 für Schlamm und Wasser oder Materialien ähnlicher Konsistenz ausgebildet. Der Anschluss 1.2 befindet sich im oberen Teil des Aufnahmebehälters 1.6 und der Anschluss 1.3 befindet sich im unteren Teil des Aufnahmebe- hälters 1.6, vorzugsweise dem Anschluss 1.2 diametral gegenüberliegend.A sludge extractor 1 according to the invention comprises a housing 1.1, on which a connection 1.2 for a suction element 3 and a connection 1.3 for a drainage element 5 is formed. The housing 1.1 is also formed in its upper region remote from the floor as a cover 1.4 which is detachably fastened to the lower housing 1.1. On the bottom, the housing 1.1 is provided with a foot element 1.5. The interior of the housing 1.1 is designed in its central region as a receiving container 1.6 for sludge and water or materials of a similar consistency. The connection 1.2 is in the upper part of the receptacle 1.6 and the connection 1.3 is in the lower part of the receptacle 1.6, preferably diametrically opposite the connection 1.2.

Oberhalb des Aufnahmebehälters 1.6, also oberhalb des Bereichs in dem Gehäuse 1.1, der mit Schlamm und Wasser gefüllt werden kann, ist ein Motor 1.7, vorzugsweise ein Elektromotor, angeordnet, der eine allgemein bekannte Saugeinrichtung 1.8, wie z. B. ein luft- ziehendes Flügelelement, antreibt. Während des Antriebs wird Luft aus dem Aufnahmebehälter 1.6 angesaugt und über Öffnungen im oberen Gehäusebereich nach außen abgegeben. Dadurch entsteht im Aufnahmebehälter 1.6 und im Saugelement 3 ein Unterdruck.Above the receptacle 1.6, ie above the area in the housing 1.1 that can be filled with mud and water, a motor 1.7, preferably an electric motor, is arranged, which has a well-known suction device 1.8, such as. B. drives an air-drawing wing element. During the drive, air is sucked out of the receptacle 1.6 and released to the outside via openings in the upper housing area. This creates a negative pressure in the receptacle 1.6 and in the suction element 3.

Der Motor 1.7 ist mit einer elektrischen Schaltung 1.9 verbunden. Die elektrische Schal- tung 1.9 befindet sich in der Nähe der vorgesehen maximalen Füllstandsgrenze des Aufnahmbehälters 1.6 in einer Saugöffnung 1.10 der Saugeinrichtung 1.8. In dem Aufnahmebehälter 1.6 ist ein Führungsgehäuse 5 für einen Schwimmer 7 ausgebildet. Der Schwimmer 7 kann sich in dem Führungsgehäuse entlang einer Längsachse des Gehäuses 1.1 bewegen und ist, wie auch die elektrische Schaltung 1.9, die Saugeinrichtung 1.8 und der Motor 1.7 konzentrisch zu dieser angeordnet. In anderen Aus-f-ührungsformen muß eine konzentrische Anordnung nicht zwingend vorgesehen sein. Der Schwimmer 7 weist an einer bodenfernen, oberen Seite einen Permanentmagneten 7.1 auf. Bei zunehmender Füllung des Aufnahmebehälters 1.6 wird der Schwimmer 7 in dem Führungsgehäuse 5 entlang der Längsachse nach oben bewegt. Kurz vor Erreichen der maximalen Füllstandsgrenze wirkt der Permanentmagnet 7.1 auf die ihm in der Saugöffnung 1.10 gegenüber liegende elektrische Schaltung 1.9 und schließt diese. Dadurch wird der Motor 1.7 abgeschaltet. Bei Erreichen der maximalen Füllstandsgrenze verschließt der Schwimmer 7 auch die Säugöffnung 1.10. Die elektrische Schaltung 1.9 ist in der vorliegenden Ausführungsforin vorzugsweise eine Reedschaltung. In anderen Ausfuhrungsformen können aber auch andere Schalter und Schaltsysteme verwendet werden. Die elektri- sehe Schaltung 1.9 ist mit einem Zeitschalter (nicht dargestellt) verbunden, der so eingestellt werden kann, daß der Motor 1.7 automatisch wieder eingeschaltet wird, nachdem der Aufnahmebehälter 1.6 über das Ablaufelement 5 vollständig entleert worden ist. Die für eine vollständige Entleerung benötigte Zeit ist abhängig von dem zu entleerenden Volumen und ist vorbestimmbar.The motor 1.7 is connected to an electrical circuit 1.9. The electrical circuit 1.9 is located near the maximum fill level limit of the receptacle 1.6 provided in a suction opening 1.10 of the suction device 1.8. A guide housing 5 for a float 7 is formed in the receptacle 1.6. The float 7 can move in the guide housing along a longitudinal axis of the housing 1.1 and, like the electrical circuit 1.9, the suction device 1.8 and the motor 1.7 are arranged concentrically therewith. In other embodiments, a concentric arrangement need not necessarily be provided. The float 7 has a permanent magnet 7.1 on an upper side remote from the floor. With increasing filling of the receptacle 1.6, the float 7 is moved upward in the guide housing 5 along the longitudinal axis. Shortly before the maximum fill level limit is reached, the permanent magnet 7.1 acts on the electrical circuit 1.9 opposite it in the suction opening 1.10 and closes it. As a result, the engine 1.7 is switched off. When the maximum fill level is reached, the float 7 also closes the feeding opening 1.10. In the present embodiment, the electrical circuit 1.9 is preferably a reed circuit. In other embodiments, other switches and switching systems can also be used. The electrical circuit 1.9 is connected to a timer (not shown), which can be set so that the motor 1.7 is automatically switched on again after the receptacle 1.6 has been completely emptied via the drain element 5. The time required for complete emptying depends on the volume to be emptied and can be predetermined.

Das Ablaufelement 5 ist an dem Anschluß 1.3 in allgemein bekannter Weise lösbar befestigt und umfaßt an seinem freien Ende 5.1 ein Unterdruckventil 5.2. Das Ablaufelement 5 ist ebenfalls ein Schlauch oder ein Rohr.The drain element 5 is releasably attached to the connection 1.3 in a generally known manner and comprises a vacuum valve 5.2 at its free end 5.1. The drain element 5 is also a hose or a tube.

Die Funktionsweise ist nun wie folgt: Das Saugelement 3 hängt mit einem Saugrüssel 3.1 im Wasser oder einem sonstigen flüssigen Fluid. Durch Einschaltung des Motors 1.7 beginnt ein Saugvorgang. Über den Saugrüssel wird beispielsweise Schlamm vom Teichboden eines Teiches durch das Saugelement 3 und die Saugöffnung 1.10 in den Aufnahmebehälter 1.6 gesaugt. Der Aufnahmebehälter 1.6 und das Ablaufelement 5 bis zum Unter- druckventil 5.2 füllen sich langsam mit Schlamm. Das Unterdruckventil 5.2 ist wegen des herrschenden Unterdruckes geschlossen. Unmittelbar vor Erreichen der maximalen Füllstandsgrenze im Aufnahmebehälter 1.6 wirkt der Permanentmagnet 7.1 auf die elektrische Schaltung 1.9, wodurch der Motor 1.7 abgeschaltet wird. Bei Erreichen der maximalen Füllstandsgrenze verschließt der Schwimmer 7 auch die Säugöffnung 1.10.The method of operation is now as follows: The suction element 3 hangs in the water or another liquid fluid with a suction nozzle 3.1. When the motor 1.7 is switched on, a suction process begins. Sludge, for example, is sucked from the pond bottom of a pond through the suction element 3 and the suction opening 1.10 into the receptacle 1.6. The receptacle 1.6 and the drain element 5 to the vacuum valve 5.2 slowly fill with mud. The vacuum valve 5.2 is closed due to the prevailing vacuum. Immediately before the maximum fill level in the receptacle 1.6 is reached, the permanent magnet 7.1 acts on the electrical circuit 1.9, as a result of which the motor 1.7 is switched off. When the maximum fill level is reached, the float 7 also closes the feeding opening 1.10.

Dabei kann der Saugrüssel 3.1 unverändert im Wasser hängen bleiben. Am Saugrüssel 3.1 ist ein Rückschlagventil 3.2 in dem Saugelement 3 angeordnet. Das Rückschlagventil 3.2 kann z.B. als Schnüffelventil aus Elastomer/Gummi einteilig ausgebildet sein. Bei Ab- oaslöl5b Schaltung des Motors 1.7 wird dadurch verhindert, daß das im Saugelement, z. B. einem Schlauch von 5 m Länge, nicht in den Teich zurück strömt und dort Schmutz aufwirbelt. Das Rückschlagventil 3.2 wird vorzugsweise aus vier Gummilappen gebildet. Durch das Ausschalten des Motors 1.7 entfallt der Unterdrück im Aufnahmebehälter 1.6, so daß das Unterdruckventil 5.2 aufgrund des nun durch den Schlamm erzeugten Innendrucks öffnet und der Schlamm über das Ablaufelement 5 ausläuft, bis der Aufnahmebehälter 1.6 wieder leer ist. Dann kann der Motor 1.7 wieder eingeschaltet werden, so daß sich der Vorgang wiederholt. The proboscis 3.1 can remain stuck in the water. A check valve 3.2 is arranged in the suction element 3 on the proboscis 3.1. The check valve 3.2 can, for example, be constructed in one piece as a snifting valve made of elastomer / rubber. With Aboaslöl5b Circuit of the motor 1.7 is prevented by the fact that in the suction element, for. B. a hose of 5 m in length, does not flow back into the pond and whirls up dirt there. The check valve 3.2 is preferably formed from four rubber tabs. By switching off the motor 1.7, the vacuum in the receptacle 1.6 is eliminated, so that the vacuum valve 5.2 opens due to the internal pressure now generated by the sludge and the sludge runs out through the drain element 5 until the receptacle 1.6 is empty again. Then the motor 1.7 can be switched on again, so that the process is repeated.
