FILTER CART Russian patent published in 2010 - IPC B01D27/00 B29C45/14 

FIELD: mechanics.

SUBSTANCE: proposed filter cart filled with filtration material represents an open barrel closed by cover from top and has sidewalls and bottom closed by at least one water-permeable material. Said water-permeable material extends to sidewall outer edges and consists of small-diametre fibers that allow using powder filtration material. Total space between wall inner and outer edges, along bottom perimetre, represents a composite made from polymer and water-permeable material. The latter is made from polyester or polyolefin fibers, or polyamide fibers, or microfibers. Cart bottom can have stiffness ribs.

EFFECT: higher rate of filtration.
