FILTERING DEVICE, PARTICULARLY FOR HEATING SYSTEMS Russian patent published in 2023 - IPC B01D35/06 

FIELD: filtering.

SUBSTANCE: filtering device (10) includes a housing (11), which forms a flow space (12) for the liquid to be filtered, and which is provided with at least two nozzles (13, 14a, 14b) for connection to the pipe. The space (12) contains a magnetic filtration chamber (15) and a mechanical filtration chamber (16) and contains a flow hole (17) communicating with the magnetic filtration chamber (15), so that the fluid that passes through the space (12) flows through one first (13) of the nozzles (13, 14a, 14b) and flowing out through one second (14a, 14b) of the nozzles (13, 14a, 14b) or vice versa, passes sequentially through both chambers (15, 16). The magnetic filtration chamber (15) contains a magnetic element (18), the working end (19) of which extends towards the flow hole (17). The mechanical filtration chamber (16) contains a strainer. The working end (19) is located at a distance from the flow hole (17), so that the accumulation of particulate material at the working end (19) does not prevent the passage of liquid from the magnetic filtration chamber (15) to the mechanical filtration chamber (16) through the flow hole (17).

EFFECT: increased efficiency of the device, simplification of its maintenance.
