FILTERING APPARATUS Russian patent published in 2022 - IPC B01D35/06 B01D29/11 B01D29/86 B01D29/90 

FIELD: filtration.

SUBSTANCE: invention relates to a filtering apparatus (10) containing: a filter body (11) containing an outer container (25) with an internal volume (26) and a cartridge element (27) configured to be inserted removably in the inner space (26), wherein the filter body (11) has an inlet (12), an outlet (13), and a flow space (14) extending along the direction of extension (A) between the upper edge (15) and the lower edge (16), in communication with said inlet (12) and said outlet (13), wherein the flow space (14) extends along the direction of extension (A) and has an inner surface (21) curved around the direction of extension (A); a mesh filter (17) containing or formed of a mesh cylinder, configured to divide the flow space (14) into an inlet chamber (18) and an outlet chamber (19), located, respectively, before and after the mesh filter (17) relative to the flow of liquid crossing the flow space (14) from the inlet (12) to the outlet (13); a magnetic element (20) extending from the upper edge (15) into the flow space (14) along the direction of extension (A) coaxially with the mesh filter (17) and the inner side of the outer container (25) for interaction with the flow of liquid crossing the flow space (14) during use. The filter is characterised by the inner surface (21) of the filter body (11) containing a reflective surface (24) configured to divert the flow of liquid entering the flow space (14) through the inlet and configured to impart the flow of liquid entering the flow passage (14) through the inlet (12) a spiral movement directed from the upper edge (15) to the lower edge (16) in order to impart tension to the flow of liquid under the impact of centrifugal forces, so that said filtering apparatus is made so that the fluid flow entering the flow space (14) through the inlet (12) is directed towards the lower edge (16) and then flows back upwards into the inlet chamber (18), goes over the magnetic element (20) and crosses the mesh filter (17) before flowing through the outlet chamber (19) towards the outlet (13).

EFFECT: proposed invention provides high filtering capacity without increasing the complexity of the filtering apparatus.
