Title
(DE) DICKSTOFFPUMPE
(EN) THICK MATTER PUMP
(FR) POMPE A MATIERES EPAISSES
Abstract
(DE) Die Erfindung bezieht sich auf eine Dickstoffpumpe, insbesondere eine Betonpumpe, mit einem Materialaufgabebehälter (14), zwei mit ihren stirnseitigen Öffnungen (22) in das Innere des Materialaufgabebehälters (14) mündenden Förderzylindern (10), einem in den Materialaufgabebehälter (14) eingreifenden, mit seinem einen Ende taktweise abwechselnd mit den stirnseitigen Öffnungen (22) der Förderzylinder kommunizierenden und mit seinem anderen Ende an ein Förderrohr (42) angeschlossenen Schwenkrohr (16) und mit einer in der Nähe des schwenkrohrseitigen Endes des Förderrohrs (42) oder in einem außerhalb des Materialaufgabebehälters angeordneten Abschnitt des Schwenkrohrs (16) in der betreffenden Rohrwand angeordneten verschließbaren Reinigungsöffnung (80). Erfindungsgemäß ist an die Reinigungsöffnung (80) eine Reinigungspatrone (86) anschließbar, die einen Preßluft- und/oder Druckwasseranschluß (90, 92) aufweist, während das Förderrohr (42) und/oder das Schwenkrohr (16) förderzylinderseitig mittels eines Absperrorgans (94, 96, 98) verschließbar ist.
(EN) The invention relates to a thick matter pump, especially a concrete pump, with a material feed container (14), two conveyor cylinders (10) opening at the front (22) into the inside of the material feed container (14), a swivelling pipe (16), one end of which alternately in pulses communicates with the frontal apertures (22) in the conveying cylinder and the other end being connected to a conveyor pipe (42) and with a closable cleaning aperture (80) in the appropriate pipe wall arranged near the end of the conveyor pipe (42) or in a section of the swivelling pipe (16) outside the material feed container. According to the invention, a cleaning cartridge (86) can be connected to the cleaning aperture (80) having a compressed air and/or pressurised water connection (90, 92) while the feed pipe (42) and/or the swivelling pipe (16) can be closed on the conveyor cylinder side by means of a blocking system (94, 96, 98).
(FR) L'invention concerne une pompe à matières épaisses, notamment une pompe à béton, comportant un récipient d'alimentation en matière (14), deux cylindres de transport (10) débouchant par leurs ouvertures frontales (22) à l'intérieur du récipient d'alimentation en matière (14), un tube articulé (16) engagé dans le récipient d'alimentation en matière (14), communiquant périodiquement et de façon alternée avec les ouvertures frontales (22) des cylindres de transport par l'une de ses extrémités et raccordé par l'autre de ses extrémités à un tuyau de transport (42), ainsi qu'une ouverture de nettoyage (80) pouvant être obturée, située à proximité de l'extrémité du tuyau de transport (42) du côté du tube articulé ou dans une partie du tube articulé (16) se trouvant à l'extérieur du récipient d'alimentation en matière dans la paroi concernée du tube. Une cartouche de nettoyage (86), pouvant être raccordée à l'ouverture de nettoyage (80), présente un raccord pour l'air comprimé et/ou pour l'eau sous pression (90, 92), tandis que le tuyau de transport (42) et/ou le tube articulé (16) peuvent être obturés du côté du cylindre de transport au moyen d'un organe d'obturation (94, 96, 98).
