Device for Reducing Friction Between Sealing Plates of Filtration Units, and Use Thereof in a Filtration Method

摘要

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, characterised 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.

1. A device for reducing the friction between two plates of a filtration unit, driven in relative rotation while being subjected to axial forced, said plates being respectively supported by the longitudinal end of a drum secured to a rotating shaft mounted on a bearing and having internal collectors and the facing end of a box locked in rotation and supported by said shaft, wherein it comprises at least one traction system acting on the box by exerting a force designed to at least partially compensate the axial forces pressing the plate against the plate to reduce the friction while ensuring maintenance of a mutual sealing contact.
