Device For Filtration With A Set Of Least One Filter Cassette

摘要

The invention concerns a filtration device comprising a providing fluid connection and mechanical connection comprising a clamping plate movably mounted relative to the manifold and adapted to compress at least one cassette against the manifold, means for driving and guiding the clamping plate comprising a rod extending between the manifold and the plate, an actuator provided with a body and a member moveable relative to the body, which member is adapted to move through a predetermined travel between an extended position and a retracted position, the body being carried by the manifold, and the member carrying the rod and driving the plate via the rod to a clamped position in which the member is in an intermediate retracted position in which it has moved through a shorter travel than the predetermined travel relative to its extended position.

主权项

1. A device for filtration with a set of at least one filter cassette comprising:
a manifold having a substantially parallelepiped shape and providing fluid connection and mechanical connection comprising at least one flow inlet for a fluid to treat, at least one flow outlet for a treated fluid and a network for conveying said fluid to treat and said treated fluid, said manifold comprising at least one main side on which is formed a bearing surface for said at least one filter cassette, through which bearing surface emerge cassette feed ports and cassette return ports communicating with said conveying network, which cassette feed ports and cassette return ports are configured to communicate with conduits formed in a said filter cassette bearing against said bearing surface; said manifold further comprising at least one lateral side and an upper face and a lower face opposite said upper face, wherein said at least one flow inlet and said at least one flow outlet are formed in at least one of said upper face and lower face; a clamping plate; and at least one rod which extends between said manifold and said clamping plate and at least one actuator, which is provided with a body and a member moveable relative to said body for driving and guiding said clamping plates parallel to and facing said bearing surface, which moveable member has an extended position and a retracted position in which said moveable member has been moved through a predetermined travel relative to its extended position, by virtue of which the clamping plate has a starting position in which said plate is away from said set of at least one filter cassette and a clamped position in which said plate is approached and compresses said set of at least one filter cassette against said manifold; said body of said at least one actuator being mounted on said at least one lateral side; wherein said body is carried by said manifold; said moveable member carries said rod; and said actuator, said rod and said clamping plate are configured such that said actuator drives said clamping plate via said rod to its clamped position in which said moveable member is in an intermediate retracted position in which said moveable member has moved through a shorter travel than said predetermined travel relative to its extended position.
