FIELD: mechanics.

SUBSTANCE: proposed device incorporates casing with cylindrical filtration rotor and flow swirling reduction device. Filtration rotor drive represents vanes, part of them being rigidly fixed along one circumference on the filter casing inner surface and the other part being shifted along the horizontal line towards filtrate outlet side and rigidly fixed on one circumference on the rotor outside surface. Angle between vanes fitted on the casing and those on the rotor is taken to equal 90°. The aforesaid flow swirling reduction device represents a screen arranged ahead of the contaminant collector. Guide plates are arranged between the said filtration rotor and the screen at an angle to the said screen.

EFFECT: simpler design and possibility of cutting in pipeline.
