AUTOMATICALLY REGENERATED FILTER Russian patent published in 2016 - IPC B01D29/66 

FIELD: filtering devices.

SUBSTANCE: invention relates to automated filtering devices with ability to regenerate filter elements and can be used in power generation, transportation, petrochemical and other industries for fine purification of fuels, oils and other fluids. Automatic regenerated filter includes housing (1) with nozzle (7) for outlet of cleaned product, lower chamber (8) with drainage nozzle (12), inlet nozzle for contaminated product (10), drainage nozzle (11) of filter chamber (2), upper cover (9) with motor-reducer (16) on a support, shaft (17) with fixed positioning unit (29). Inside housing (1) are installed filtration chambers (2) for arrangement therein of filtering elements (3) with filtration from outside to inside in form of shells with blind bottom with a given degree of filtration with inner and outer bearing frames. Cover (9) is equipped with nozzle (13) for supply of cleaning substance for regeneration, equipped with vent (14). Shaft (17) is located with a gap in radial through-hole (34) made in upper pipe plate (5) and plate (6). Upper and lower ends of shaft (17) are hollow. On upper end is fixed said regeneration assembly (29), on one end of which there is check valve (30), and on lower end of shaft is fixed branch (32) for drain removal from regenerated filtration chamber (2). Regeneration assembly (29) and branch (32) for drain removal are located in one plane, and adherence of regeneration assembly to plate (6) and branch for drain removal to lower pipe plate (4) is provided by a spring-loaded sleeve with possibility of axial movement and made from antifriction material.

EFFECT: technical result is high efficiency of regenerating filtering elements, longer life of filter.
