DEVICE FOR TRAPPING DUST Russian patent published in 2007 - IPC B04C9/00 B01D46/52 

FIELD: dust trapping engineering.

SUBSTANCE: device comprises housing, peripheral input for gas flow, filtering member, and hopper for collecting dust. The peripheral gas flow input lies in the central part of the device and is made of an inlet branch pipe connected with the housing of the cyclonic member at the right angle. The cyclonic member is made of two axially aligned branch pipes. One of the branch pipes is provided with the filtering member made of a cassette filter made of a filtering corrugated paper and mounted in the wire frame. The other branch pipe is provided with a hopper for collecting dust made of a dust collecting bag. The cassette filter has a regeneration mechanism made of at least two plates secured to the shaft that is coaxially mounted with respect to the filter. The plates enter the hollows of corrugation. The shaft is made for permitting rotation by means of the drive secured in the top section of the wire filter frame. The drive comprises electric motor and reduction gear. The cyclonic member is made of a scroll-shaped housing provided with the fan . The branch pipe connected with the dust-collecting bag receives the insert made of a cylindrical sleeve.

EFFECT: enhanced efficiency and reliability.
