Description
Vorrichtung zur Filtration von Flüssigkeiten mitDevice for the filtration of liquids with
konfektionierten Filterelementen.assembled filter elements.
Gegenstand der Erfindung ist eine Vorrichtung zur Filtration von Flüssigkeiten mit Hilfe von konfektionierten, auch nach Gebrauch umweltunschädlich transportablen Filterelementen.The invention relates to a device for filtering liquids with the help of ready-made, environmentally safe transportable even after use Filter elements.
Die Verwendung konfektionierter Filterkörper, sogenannter Filterkartuschen, ist seit Jahren in der Technik bekannt, zum Beispiel in Chemischreinigungsanlagen. Das ungelöste Problem bestand bisher darin, daß die verbrauchten Filterkörper mit Resten der filtrierten Flüssigkeiten getränkt sind ( im Beispielsfall mit fluorierten und/oder chlorierten Kohlenwasserstoffen ), sodaß Transport und Vernichtung mit Gefahren für die Umwelt verbunden waren.The use of prefabricated filter bodies, so-called filter cartridges, has been known in technology for years, for example in dry cleaning systems. The unsolved problem has been that the used filter body with Residues of the filtered liquids are soaked (in the example with fluorinated and / or chlorinated hydrocarbons), so that transport and destruction with Environmental hazards.
Die angemeldete Erfindung bezweckt den umwelt neutralen Transport und die unschädliche Lagerung der verbrauchten Filterelemente, indem sie Transportbehälter und Druckgefäß für den Filtrationsvorgang in einem Gegenstand vereinigt.The registered invention aims at environmentally neutral transport and the harmless storage of the used filter elements by placing them in transport containers and pressure vessel for the filtration process combined in one object.
Erfindungsgemäß werden Filterkörper der bisher bekannten Art mit formbeständigen, zylinderförmigen Umhüllungen versehen, die mit ihnen zusammen ein Filterelement bilden.According to the invention, filter bodies of the previously known type with dimensionally stable, provided cylindrical envelopes, which together with them a filter element form.
Die Umhüllungen sind vollständig geschlossen. Für die Zeit der Einschaltung der Filterelemente in einen bestimmungsgemäßen Filterkreislauf werden Zu- und Abgangsöffnungen freigegeben.The casings are completely closed. For the time of activation of the filter elements in an intended filter circuit are inlet and outlet openings Approved.
Zum Zweck der Auswechselung der Filterkörper in den Filterelementen werden letztere mit einem Deckel versehen, der sich nur mit einem Werkzeug öffnen läßt. Zur umweltneutralen Auswechselung der Filterkörper wird die gleichzeitig angemeldete Vorrichtung zur Rückgewinnung von Flüssigkeiten aus konfektionierten Filterelementen" vorgeschlagen.For the purpose of replacing the filter bodies in the filter elements the latter are provided with a lid that can only be opened with a tool leaves. For an environmentally neutral replacement of the filter body, the one registered at the same time is required Device for the recovery of liquids from assembled filter elements " suggested.
Beschreibung der Vorrichtung: Die Filterkörper (3) sind in die Behälter (1) durch Führungsschienen (4), Distanzring (8) und Dichtungen (2) so eingesetzt, daß im Betrieb das zu filtrierende Medium bei (6) eintritt und bei (7) austritt. Der Deckel (10) wird durch Bajonettverschluß (5) befestigt und durch Dichtung (11) gegen den Behälter abgedichtet. Die Ein-und Austrittsstutzen (6 und 7) sind als selbstätig schließende Ventile ausgebildet, die bei Anschluß an passende Gegenstücke öffnen.Description of the device: The filter bodies (3) are in the container (1) inserted through guide rails (4), spacer ring (8) and seals (2) so that that during operation the medium to be filtered enters at (6) and exits at (7). The cover (10) is fastened by a bayonet lock (5) and secured by a seal (11) sealed against the container. The inlet and outlet nozzles (6 and 7) are as self-closing valves formed when connected to matching counterparts to open.
