FILTERING DEVICE WITH DRUM SCREEN FOR MEDIUM VISCOSITY AND HIGH VISCOSITY FLUIDS AND METHOD OF ITS SEALING AND MOUNTING Russian patent published in 2019 - IPC B29C48/69 

FIELD: filtering devices.

SUBSTANCE: invention relates to a filtration device with a drum sieve for medium viscosity and high-viscous fluids. Filtration device (100) with a drum sieve for medium viscosity and high viscosity fluids, which includes drum screen (20) installed in body (10) with possibility of rotation with at least one flow-permeable sieving element (21), drum sieve (20) in area of their sealing surfaces (22) and intermediate plates (15) are made or processed together so that they have identical height. Then between inlet plate (12) and intermediate plate (15) and / or between outlet plate (11) and intermediate plate (15) layer (16) of gap width adaptation is introduced. Finally, pack of plates (11, 12, 15) is pre-clamped by screws (17) so that all plates (11, 12) fit tightly to each other up to maximum allowable working pressure (p₀). Lubrication gaps (25, 26) of defined width are created between sealing surfaces (22) and opposite inner surfaces of inlet and outlet plates (11, 12).

EFFECT: invention provides economical manufacturing, as well as subsequent cost-effective adaptation of filtering devices for use with other fluids and / or other operating parameters.
