FILTER FOR LIQUIDS Russian patent published in 2004 - IPC

FIELD: liquids filtration.

SUBSTANCE: the invention is intended for filtration. It presents a filter (1) for the liquids, which consists of a filled with a filtering material (4) barrel-shaped body (2), in the bottom (3)of which there is at least one mesh-type outlet for a liquid, and a cover (5), which restricts an internal volume (V_i) and has at least one inlet (8) for a liquid and one ventilation outlet (10) for an air outlet and by a pressure-tight, liquid-proof link is fused with the barrel-shaped body (2). At that between the barrel-shaped body (2) and the cover (5) there is a mesh insert (12) made out of a textile lining. With the purpose to ensure a reliable operation of the filter with simultaneous efficient retention of the particles of a size about 200 microns, including the case of a different level of the barrel-shaped body infilling with a filter material, the design provides that the mesh insert (12) made out of a textile linen has at least one part (13) protruding inside the internal volume (V_i) of the cover (5) in such a manner that on both sides of the most removed from the barrel-shaped body(2) sections (14) of this insert (12) made out of a textile lining during the most time of the whole filtration process period the air is present.

EFFECT: the invention ensures a reliable operation of the filter with simultaneous efficient retention of the particles of a size about 200 microns during the whole process of filtration.
