Title: ROTARY SCREEN FILTERING DEVICE FOR MEDIUM TO HIGH-VISCOSITY FLUIDS AND SEALING AND MOUNTING METHOD THEREFOR
Abstract:
On a rotary screen filtering device (100) for medium to high-viscosity fluids, which comprises a rotary screen (20) mounted for rotation in a housing (10), which screen has at least one screen element (21) through which fluid can flow, the rotary screen (20), in the region of its sealing faces (22, 23, 24) and the intermediate plates (13, 14, 15) are fabricated or machined together so that they are of identical height. A gap width compensation layer (16) is then inserted between the inlet plate (12) and the intermediate plate (15) and/or between the outlet plate (11) and the intermediate plate (15). The package of plates (11, 12, 13, 14, 15) is then pretensioned by means of screw bolts (17) in such a manner that all the plates (11, 12, 13) lie firmly against one another up to a maximum permissible operating pressure (p0). Lubrication gaps (25, 26) of defined width are created between the sealing faces (22, 23, 24) and the opposing inner faces of the inlet and outlet plates (11, 12).
