Method and means for pressure filtering

In an apparatus for pressure filtering in a press filter (1) for the removal of liquid from a suspension of solid particles in said liquid, said press filter comprising a number of press plates (3, 4, 5, 6), which can be pressed against each other and are provided with drain channels, said press plates two and two between themselves forming at least one pressure chamber (8), two substantially vertical filter cloths (9), suspension means (18) for suspending two filter cloths in each of said pressure chambers (8), a feed supply conduit to introduce said suspension under pressure between the filter cloths (9) in said pressure chamber (8), said liquid being removed under the influence of the inlet pressure, through the filter cloths (9), and through the drain channels (10, 12) of the press plates, while the solid particles in the form of filter cakes (40) remain between the filter cloths (9), and means to separate the press plates (3, 4, 5, 6) to discharge the filter cakes from the pressure chambers (8), the improvement wherein said press filter further includes:

• guide rails supporting said suspension means (58) of the filter cloths (9) at both ends for horizontal movement in the longitudinal direction of the press filter, said guide rails being resiliently suspended, and vibration means (98) for simultaneous vibrating of all suspension means (58) with appending filter cloths (9), and distance means (94) affixed to the ends of said suspension means, said distance means connecting the suspension means with each other and with the press plates.
