DUST SEPARATOR Russian patent published in 2011 - IPC B01D45/12 B04C5/02 

FIELD: process engineering.

SUBSTANCE: invention relates to air cleaning and may be used in chemical industry or production of construction materials, namely, in aspiration systems. Proposed device comprises casing, truncated-cone suction funnel with its larger base jointed with the casing, aspiration air duct, taper dust separator arranged aligned with suction funnel and aspiration air duct. Atop said separator suction elements are arranged, while at its bottom dust collector is mounted. Suction elements are made up of tangential branch pipes. Annular chamber is arranged to revolve about said branch pipes and provided with openings, their number corresponding to that of tangential branch pipes and sizes mating that of inlet of the latter. Swirler made up of a tube section communicated with tangential inlets is arranged at taper dust separator bottom. Baffle washer is attached to said tube section. Said annular chamber is revolved by drive made up of handle engaged with gear wheel in mesh with teeth made along the chamber edges.

EFFECT: higher efficiency, reduced loss of loose material, smaller sizes.
