Abstract: The present invention relates to a device and a method for reducing friction between two plates (4, 5) of a filtration unit, said plates being rotated relative to one another by being subjected to axial pressing forces, said plates being supported by the longitudinal end of a drum (1) secured to a rotary shaft (3) mounted on a bearing (6) and having internal collectors (11), and the opposite end of a casing (2) which is rotatably locked and supported by said shaft, respectively, characterized in that it includes at least one pulling system (8) engaging with the casing (2) by exerting a force intended to at least partially compensates for the axial forces pressing the plate (5) against the plate (4), in order to reduce friction while ensuring that tight mutual contact is maintained.

Abstract: The present invention relates to a device for extracting cakes resulting from pressurized filtration from a sealed tank (1) in which rotary filters (2) are provided, the tank being provided with a hopper (1b) for recovering solid particles and having an extension, in the lower portion thereof, in the form of a hatch (10) defined between at least two temporary blocking members (11, 12), characterized in that each temporary blocking member includes a rotary shaft (100) transversally arranged in the hatch and bearing at least one set (101, 102, 103) of two diametrically opposite radial fins having a global surface substantially corresponding to the cross-section of the hatch (10) and optionally at least one set of two radial forks (104, 105), as well as peripheral sealing means(102) mounted on the inner wall of the hatch opposite the end edge of said fins. The invention also relates to an associated extraction method.
