FILTERING DEVICE AND METHOD FOR PREPARING WATER Russian patent published in 2021 - IPC B01D33/73 

FIELD: water filtration.

SUBSTANCE: filtering device (1) for water preparation contains inlet pipe (2) for supplying source water to be purified and filter unit (3) covering inlet pipe (2), made with the possibility of rotation around axis of rotation (A-A) and containing elements (31) of a mesh filter for the passage of source water into tank (4) for filtered water surrounding filter unit (3). Elements (31) of the mesh filter extend parallel to axis of rotation (A-A) along the length of filter unit (3) and have a triangular cross-sectional shape with a vertex located radially outward of elements (31) of the mesh filter. Each element (31) of the mesh filter includes filter mesh (33) made of stainless steel or plastic and having a cell size from 5 to 100 mcm. Filter unit (3) is mounted with the possibility of rotation on inlet pipe (2) by means of bearing (22), and filtering device (1) also includes a Zimmer sealing ring on bearing (22) for hermetically sealing the inner space of filter unit (3) so that source water enters tank (4) for filtered water only through element (31) of the mesh filter. The device includes sprinkler device (5) located above filter unit (3), located above gutter (34) installed in filter unit (3).

EFFECT: elimination of rapid clogging of the mesh, ensuring the possibility to filter out as small particles as possible.
