Magnetarretierte, ausbaubare Senneilmischtrenner für radioaktive FlüssigkeitenMagnetically locked, removable rope mixing separator for radioactive liquids
. Die Extraktion gelöster Stoffe aus einer Flüssigkeit mittels einer anderen Flüssigkeit erfolgt durch inniges Ver— . mischen und anschliessendes Trennen der beiden Flüssigkeiten. Zur Erzielung einer möglichst vollständigen Extraktion werden mehrere Misch- und Trennstufen hintereinander geschaltet, welche kontinuierlich im Gegenstrom arbeiten.. The extraction of solutes from a liquid by means of another liquid takes place by intimate mixing. mix and then separate the two liquids. To achieve the most complete extraction possible, several mixing and separation stages are used one after the other switched, which work continuously in countercurrent.
Sollen spaltstoff— und produkthältige, radioaktive Lösungen extrahiert werden, so müssen kurze Kontaktzeiten der beiden Flüssigkeiten erreicht werden, da sonst die verwendeten Lösungsmittel der Zersetzung durch die radioaktive Strahlung ausgesetzt sind.Should radioactive solutions containing fissile material and products are extracted, the two must have short contact times Liquids can be reached, otherwise the used solvents of the decomposition by the radioactive ones Exposed to radiation.
Die erforderlichen kurzen Kontaktzeiten werden mit dem von der Gesellschaft für Kernforschung mbH, 7500 Karlsruhe, entwickelten und zum Patent angemeldeten "Kompakten Schnell-Mischtrenner für Wiederaufarbeitungsanlagen von Kernbrennstoffen und dergleichen" (Anmeldung P 15 57068.0) erreicht.The required short contact times are provided by the Society for Nuclear Research mbH, 7500 Karlsruhe, developed and patent-pending "compact high-speed mixing separator for reprocessing plants of nuclear fuels and the like "(application P 15 57068.0).
2» Die derzeit bekannte Konstruktion für Schnellmischtrenner weist für den Einsatz in Anlagen zur Extraktion radioaktiver Lösungen eine Reihe von Nachteilen auf, die mit der erfindungsgemässen Konstruktion vermieden werden:2 »The currently known construction for high-speed mixing separators has a number of disadvantages for use in plants for the extraction of radioactive solutions, which with the construction according to the invention can be avoided:
- Der von oben in das Gehäuse eingesetzte Rotor kann unter der hohen Strahlungsbelastung nicht ausgebaut werden.- The rotor inserted into the housing from above can be underneath the high radiation exposure are not expanded.
- Der Austausch des Pumpenrades oder der Mischkammer ist nur nach vorheriger Entleerung und Reinigung der Verfahrenseinheit möglich.- The exchange of the pump wheel or the mixing chamber is only possible after the processing unit has been emptied and cleaned possible.

Jeglicher Wartungseingriff hat daher Stillstandszeiten und Dekontaminationsarbeiten nicht nur an dem Schnellmischtrenner selbst, sondern auch an allen räumlich-mit— ihm verbundenen Anlageteilen zur Folge. ... . . . ....-,-"Any maintenance work therefore has downtimes and decontamination work not only on the high-speed mixing valve itself, but also on all of the system parts connected to it. ... . . ....-, - "
Bei der erfindungsgemässen Konstruktion sind demgegenüber die bewegten Teile der Schnellmisehtreimer, ä.*h.·. · das Pumpenrad mit der daran anschliessenden Mischkammer sowie der Rotor so ausgebildet, dass sie ohne Stillegung 'des Verfahrens und ohne vorherige Dekontamination des Raumes, in dem sie sich befinden, ein- und ausgebaut werden können. ' \ In the construction according to the invention, on the other hand, the moving parts of the high- speed waste bin, etc., are. · The impeller with the adjoining mixing chamber as well as the rotor are designed in such a way that they can be installed and removed without having to shut down the process and without prior decontamination of the room in which they are located. '\

Das von der Rotorwelle (1) angetriebene Pumpenrad (2) sitzt in einer gekapselten Mischkammer (3)? die gegen Verdrehung mittels zylindrischen Passstifte gesichert istο Die Arretierung der gekapselten Mischkammer erfolgt durch paarige Permanentmagnete (5)· ~The pump wheel (2) driven by the rotor shaft (1) sits in an encapsulated mixing chamber (3)? secured against rotation by means of cylindrical dowel pins istο The encapsulated mixing chamber is locked by paired permanent magnets (5) · ~
Zum Ausbau des Schnellmischtrenners wird-zunächst der Motor (7), welcher sich ausserhalb der durch.die Abschirmwand (8) abgetrennten radioaktiven Zone befindet, abgenommen. /To remove the high-speed mixing separator, the Motor (7), which is located outside the radioactive zone separated by the shielding wall (8), removed. /
Mittels einer auf die Rotorwelle aufgesetzten Ziehhiilse werden sodann der Rotor und die Mischkammer mit dem darin befindlichen Pumpenrad aus der Strahlenabschirmung und dem Schnellmischtrennergehäuse (9) gezogen. Die entstandene öffnung in der Abschirmung wird mit einem Stopfen verschlossen. Nach Erfolg der Wartung und der Instandsetzung erfolgt der Wiedereinbau in umgekehrter Reihenfolge. Zwischenzeitlich läuft das Extraktionsverfahren ungestört weiter. By means of a pull sleeve placed on the rotor shaft, the rotor and the mixing chamber with the inside The pump wheel located in the area is pulled out of the radiation shield and the high-speed mixer disconnector housing (9). The resulting opening in the shield is closed with a stopper locked. After the maintenance and repair work has been carried out successfully, reassembly is carried out in reverse Series. In the meantime, the extraction process continues undisturbed.
