Abstract

The invention concerns a module for filtering media. More particularly, the invention concerns a module for filtering fluids and including one or more filter cells stacked on top of one another. The invention also relates to an installation set for the installation of at least one such filter module in a filter housing, as well as to a filter device with a filter housing, in which the filter module or the filter modules is/are installed together with the installation set.

Claims (9)

1. Installation set for the installation of at least one filter module in a filter housing, wherein the filter module includes one or more filter cells which are stacked one on top of the other and which each have at least one opening, wherein the opening of the filter cells or the similar openings of the cells together form at least one channel for the supply or discharge of the medium to be filtered and wherein each filter cell has two porous, planar components which limit an interior space and which can support a flow of a medium, wherein the inner space or spaces is/are connected to the channel, to upper and lower adapters arranged at the ends of the channel, and to a media-sealed enclosure device which surrounds the filter cells and which has at least one inlet or outlet opening, wherein the enclosure device includes a media-sealed envelope and upper and lower retaining rings, the envelope being attached to the retaining rings in a media-sealed fashion and each retaining ring being arranged on an adapter, wherein the filter housing has a housing base with a filtrate or nonfiltrate connection arranged in the center and an eccentric filtrate or nonfiltrate supply, a housing shell, and a housing cover wall with a housing connection arranged in the center, an annular base plate, which fills up the space between the housing base and the filter module so that the upper side of the base plate forms a contact surface for the envelope, wherein the base plate has a filtrate outlet or nonfiltrate channel, which connects the filtrate or nonfiltrate supply of the housing base to the inlet or outlet opening arranged in the lower retaining ring, and which has means for receiving the lower adapter and the lower retaining ring, and a cover plate, which fills out the space between the housing cover wall and filter module so that the lower side of the cover plate forms a contact surface for the envelope, and which has a means for receiving the upper adapter and the upper retaining ring.

2. Installation set according to claim 1 , wherein the means for receiving the lower adapter includes a receiver bushing.

3. Installation set according to claim 2 wherein the receiver bushing has a projection as a stop for a valve tappet of a valve arranged in the lower retaining ring.

4. Installation set according to claim 1 wherein the cover plate is formed in two parts and includes an annular head plate and a distributor head inserted in the center in the head plate.

5. Installation set according to claim 4 wherein the distributor head has a ventilation channel for the nonfiltrate or filtrate channel and/or a ventilation channel for the filtrate or nonfiltrate chamber and/or a control channel.

6. Installation set according to claim 1 , for the installation of at least two filter modules, wherein between every two filter modules there is an intermediate plate with an opening, which fills up the space between the two filter modules so that the two end surfaces each have a contact surface for the envelopes of the filter module and which has at least one connection channel, which connects valve openings of valves located in the retaining rings of the two filter modules to each other.

7. Filter device with the filter housing, at least one filter module and the installation set according to claim 1 .

8. Filter device according to claim 7 wherein the envelope is dimensioned such that during filtration it contacts the walls of the filter housing and the adjacent components of the installation set.

9. Filter device according to claim 7 wherein the control channel is attached to a pressure device.
