摘要:
The invention relates to a filter device comprising a non-lenticular central support layer (124) and one or more layers of relatively flat, porous fibrous filtration media (121) positioned upstream on both sides of the central support layer (124). An inner seal (131) is provided between the filtration media (121) and the support layer (124) and an outer seal (130) is formed over the filtration media (121) and the support layer (124) to form a liquid seal such that all fluid to be filtered must pass through the filtration media (121) before entering the support layer (124) and reaching an outlet of the filter device which is in fluid communication with the support layer (124).

A liquid filtration device (129) useable for removing leukocytes from blood contains a first chamber (108) which is in fluid flow relationship with a second chamber (109). Filtration elements (103) separate the first chamber (108) from the second chamber (109) so that the liquid flowing from the first chamber (108) is filtered thereby prior to entry into the second chamber (109). A passage (111) leads from the second chamber (109) into the first chamber (108) and a hydrophobic filter (104) is used to prevent liquid from the first chamber (108) from flowing through the passage (111) into the second chamber (109) while allowing air to flow therethrough. An outlet (123) is located in the second chamber (109). A second outlet (124) is located within the second chamber (109) and is placed in fluid flow relationship therewith by a conduit (116).
摘要:
A shifter mechanism for a filter press, which shifter mechanism incorporates a vibrating mechanism for effecting bumping of individual filter plates during the separation thereof from the closed stack to assist in dislodgement of filter cake from the individual filter plates. The vibrating device can selectively vibrate or bump the individual filter plates responsive to the weight of the filter plate being bumped, whereby the vibrating device will be activated only upon sensing a filter plate having a weight greater than a predetermined value so as to be indicative of an undesired quantity of filter cake being adhered thereto.

A blood filtration device encapsulates a filter pad assembly Within a flexible housing. The filter pad assembly includes first and second filter media layers. A first heat and pressure sealed region integrally bonds the peripheries of the first and second media layers together. The flexible housing comprises a peripheral rim aligned with the first heat and pressure sealed region of the first media layer. A second heat and pressure sealed region, formed after the first heat and pressure sealed region, joins the rim of the flexible housing to the first heat and pressure sealed region, thereby forming a composite seal that encapsulates the filter pad assembly within the housing.

The invention relates to a filter element, a method for manufacturing the filter element, and use. The filter element (1) is formed of a solid-liquid filter fabric (2) and has at least one separately manufactured support element (14) fastened to it. The support is a plate-like piece.
摘要:
Die Erfindung befasst sich mit einer Filterpresse zur Fest-Flüssig-Trennung von Suspensionen, welche mehrere, hintereinander geschaltete, randseitig zusammengespannte plattenförmige Filterelemente umfasst, welche mittels einer Anpressplatte gegen eine Gegenhalterplatte angedrückt werden. Jedes plattenförmige Filterelement umfasst eine Presswand, einen Plattenrahmen und auf den Stirnseiten ein Filtermittel (Filtermedium) für ein Gewebe, wie beispielsweise ein Filtertuch oder eine Membrane. Zusätzlich hat die Filterpresse einen Suspensionseinlass, welcher vorzugsweise zentrisch und mittig angeordnet ist und einen oder mehrere Filtratauslässe. Bei der erfindungsgemäßen Auslegung der Filterpresse wird wenigstens mittels eines berührungslos arbeitenden Sensors die Presswandbelastung, wie die Dehnung, die Verformung bzw. Längenänderung erfasst, und ein solcher Sensor ist wenigstens einem Filterelement zugeordnet. Mittels einer Auswerteeinrichtung werden die Sensorsignale aufgewertet und ggfs. über eine Regelungseinrichtung an eine Überwachungseinrichtung weitergeleitet. Wenn der oder die Sensoren kontinuierlich arbeiten, lassen sich Prozessparameter der Filterpresse verändern, wobei es sich insbesondere um die Beschickungsmenge, die Stoffdichte, die Einlaufdruck und die Filterkuchenbildung handeln kann.
