Device for separating particles from flowing medium
First Claim
1. A device for separating particles from flowing medium comprising:
- a cyclone member having a cylindrical inner wall;
a filter cartridge having a cylindrical casing of folded filter material disposed in said cyclone member;
a filter cleaning device engaging said folded filter material, whereby said filter cleaning device removes particles which have adhered to said folded filter material when said filter cleaning device engages said folded filter material and said filter cartridge rotates relative to said filter cleaning device;
wherein when said flowing medium is introduced into said cyclone member, coarse particles are separated in said cyclone member, fine particles are separated in said filter cartridge, and any of said fine or coarse particles adhered to said filter material are thrown outward toward said cylindrical inner wall;
said filter cartridge being rotatably mounted at a top inside of said cyclone member, and said filter cleaning device having at least one rinse finger mounted on said cyclone member and engaging said folded filter material casing;
said rinse fingers including flange portions which protrude between said folds of said filter material;
said filter cartridge further having an end wall through which said filter cartridge is rotatably mounted on said cyclone member, and wherein said end wall has an outlet opening through which medium may flow out of said filter cartridge; and
said filter cartridge being maintained in position in said cyclone member by means of a cover attachable to said cyclone member and engaging said end wall of said filter cartridge, and said end wall having a rotating device with a gear wheel cooperating with a gear ring on said end wall, whereby said filter cartridge is rotatable relative to said filter cleaning device.

Abstract
The present invention relates to a device for separating particles from flowing medium, whereby separation of coarse particles occurs in a cyclone member (4) and separation of fine particles in a filter device (10) inside the cyclone member. For providing this separation of coarse particles in a cyclone member and additionally, fine separation in a cleanable filter device, there is, inside the cyclone member (4), provided a filter cleaning device (15) which engages filter material (16) included in the filter device (10) for cleaning said filler material from particles adhering thereto when the filter device (10) is rotated relative to the filter cleaning device (15), the filter cleaning device (15) relative to the filter device (10) or the filter device (10) and the filter cleaning device (15) relative to each other.
