Abstract

A clamping device ( 1 ) is provided for cartridge filtration modules ( 2 ) that have a distribution plate ( 3 ) with a feed channel ( 18 ), a retentate channel ( 21 ), a filtrate channel, and a first contact surface ( 8 ). At least one filter cartridge can be clamped between a contact surface ( 8 ) of the distribution plate ( 3 ) and a clamping surface ( 29 ) of a clamping plate ( 4 ) that can be moved orthogonally to the contact surface ( 8 ). The cartridge filtration modules ( 2 ) can be stacked on one another in an area of their distribution plates ( 3 ). A common distribution plate ( 3 ) for adjacent filter cartridge arrangements can clamped against the contact surface ( 8 ). Adjacent filter cartridge arrangements can be connected in a parallel circuit via the distribution plate ( 3 ), and the cartridge filtration modules ( 2 ) that can be stacked on top of one another can be connected in series via the distribution plates ( 3 ).

2. The cartridge clamping device of claim 1 , wherein
the distribution plate ( 3 ) has a rear side that faces away from the first contact surface ( 8 ), the rear side having a second contact surface ( 9 ) for two further filter cartridge arrangements that can be arranged adjacent to one another and clamped against the second contact surface ( 9 ).

3. The cartridge clamping device of claim 2 , wherein
the distribution plate ( 3 ) is laterally delimited transverse to the stack direction ( 10 ) by a first lateral face ( 13 ) and a second lateral face ( 14 ), each of the lateral faces ( 13 , 14 ) running parallel to one another in the stack direction ( 10 ) and having at least one filtrate connection ( 15 ).

4. The cartridge clamping device of claim 3 , wherein
the distribution plate ( 3 ) is laterally delimited at a bottom in the stack direction ( 10 ) by a lower lateral face ( 11 ) running transverse to the stack direction ( 10 ) and at a top in the stack direction ( 10 ) by an upper lateral face ( 12 ) running transverse to the stack direction ( 10 ) and
the lower lateral face ( 12 ) has a feed connection ( 16 ) for fluid to be filtered and the upper lateral face has a retentate connection ( 17 ) for retentate to be discharged.

5. The cartridge clamping device of claim 4 , wherein
the feed channel ( 18 ), the retentate channel ( 21 ) and the filtrate channels ( 24 , 25 , 26 , 27 ) of the distribution plate ( 3 ) are arranged transverse to the stack direction ( 10 ),
the feed channel ( 18 ) is arranged with a plurality of feed inlets ( 19 ) arranged in a line, the retentate channel ( 21 ) has a plurality of retentate outlets ( 22 ) arranged in a line and the filtrate channels ( 24 , 25 , 26 , 27 ) have a plurality of filter outlets ( 28 ) arranged in a line, and
