CYCLONE SEPARATION DEVICE COMPRISING TWO CYCLONES CONNECTED BY OPTIMIZED CHANNELLING UNIT Russian patent published in 2019 - IPC B04C5/26 B04C7/00 

FIELD: centrifugal devices.

SUBSTANCE: invention relates to a device for cyclone separation of solid particles contained in a fluid medium. Device comprises primary cyclone chamber, secondary cyclone chamber, at least one fluid inlet channel communicating with primary cyclone chamber, at least one channel for discharging fluid medium cleaned from solid particles, to which secondary cyclone chamber communicates, and a channeling unit connecting the primary cyclone chamber with the secondary cyclone chamber. Said drainage unit is surrounded by primary cyclone chamber and comprises core forming boundary of secondary cyclone chamber, wherein said core has an outer surface on which at least one spiral groove is made, the bottom of which is spaced from the longitudinal axis of the secondary cyclone chamber, approaching the secondary cyclone chamber. Cap covering the core part limits with the at least one spiral groove a spiral channel having an input communicating with the primary cyclone chamber, and output communicating with secondary cyclone chamber. Cap is designed so that it is removed from the longitudinal axis of the secondary cyclone chamber, approaching this secondary cyclone chamber.

EFFECT: technical result is simplicity, efficient separation.
