The invention relates to a sludge extractor comprising an extractor element which is connected to a receiving container and a motor in order to produce a suction flow, also comprising a discharge element which is connected to the receiving container and an electric circuit for automatically disconnecting the motor and for automatically emptying the receiving container.

Claims

GEÄNDERTE ANSPRUCHE [beim Internationalen Büro am 22 April 2004 (22.04.2004) eingegangen]Neuer Patentanspruch 1 AMENDED CLAIMS [received at the International Bureau on April 22, 2004 (Apr. 22, 2004)] New Patent Claim 1
1. Schlammsauger mit einem Saugelement, das mit einem Aufnahmebehälter verbunden ist, in welchem ein flüssiges Fluid bis zu einem maximalen Füllstand gesammelt werden kann, wobei an dem Aufnahmebehälter ein Ablaufelement angeschlossen ist, in dem ein Unterdruckventil angeordnet ist, das bei Erreichen des maximalen Füllstand öffnet, und mit einem Motor zur Erzeugung einer Saugströmung, die einen Gegendruck erzeugt, der stärker ist als der im Aufnahmebehälter herrschende Unterdruck, wobei der Motor eine elektrische Schaltung aufweist, die den Motor in Abhängigkeit vom Erreichen des maximalen Füllstandes ausschaltet, wodurch sich das Unterdruckventil öffnet, dadurch gekennzeichnet, daß die elektrische Schaltung (1.9) mit einem Zeitschalter verbunden ist, der bewirkt, dass die elektrische Schaltung (1.9) den Motor (1.7) nach einer für eine vollständige Entleerung des Aufnahmebehälters (1.6) benötigten Zeitspanne wieder einschaltet.1. sludge suction with a suction element, which is connected to a receptacle in which a liquid fluid can be collected to a maximum level, wherein the receiving container, a drain member is connected, in which a vacuum valve is arranged, which when reaching the maximum level opens, and with a motor for generating a suction flow, which generates a back pressure that is greater than the prevailing in the receptacle vacuum, wherein the motor has an electrical circuit that turns off the motor in response to reaching the maximum level, thereby reducing the vacuum valve opens, characterized in that the electrical circuit (1.9) is connected to a timer, which causes the electrical circuit (1.9) turns on the motor (1.7) again after a time required for a complete emptying of the receptacle (1.6).
2. Schlammsauger nach Anspruch 1, dadurch gekennzeichnet, daß die elektrische Schaltung (1.9) einen in einem Gehäuse (1) geführten Schwimmer (5) aufweist, in dem ein Permanentmagnet (7) angeordnet ist, der bei Erreichen des maximalen Füllstandes die elektrische Schaltung (1.9) und eine Säugöffnung (1.10) schließt.2. Sludge suction device according to claim 1, characterized in that the electrical circuit (1.9) in a housing (1) guided float (5), in which a permanent magnet (7) is arranged, which upon reaching the maximum level, the electrical circuit (1.9) and a mammal opening (1.10) closes.
3. Schlammsauger nach Anspruch 2, dadurch gekennzeichnet, daß der Permanentmagnet (7.1) derart ausgelegt ist, daß zuerst die elektrische Schaltung (1.9) schließt und dann die Saugöffnung (1.10).3. Sludge sucker according to claim 2, characterized in that the permanent magnet (7.1) is designed such that first the electrical circuit (1.9) closes and then the suction opening (1.10).
4. Schlammsauger nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß das die elektrische Schaltung (1.9) ein Reedschalter ist. 4. sludge suction according to claim 1 or 2, characterized in that the electrical circuit (1.9) is a reed switch.
