FILTERING DEVICE FOR PLASTIC MELT OR OTHER HIGH-VISCOSITY FLUID MEDIUM Russian patent published in 2020 - IPC B29C45/24 B29C48/694 B29C48/25 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to filtration device (100) for plastic melt or other high-viscous fluid medium. Filtering device includes housing (10) with inlet plate (11) and outlet plate (12). At least one remote element (15, 16) is located between them and sieving wheel (20) rotating by drive device (30). By means of at least three clamping elements (17.1...17.6) of the housing input plate (11) and output plate (12) are clamped relative to each other with intermediate connection of remote element (15, 16). Engagement point (32) of drive device (30) on sieving wheel (20) is located outside surface (40) of prestress. On sieving wheel (20) between first line (45), which is distributed between center (43) of gravity of surface (40) of prestress, on which the resulting force F_R acts friction, and central point (18) of sieving wheel (20), and second line (46) between central point (18) and engagement point (32), on which force F_V acts feeding, is formed, if seen in direction of rotation, angle α more than 110° and less than 160°.

EFFECT: optimization of preliminary prestress in the housing sufficient for tightness and gap width required for lubrication and mobility of a sieving wheel.
