Abstract
A purifying device provided with a device (26) for collecting particles, such as dust. includes a chamber (28) having an inner wall (30) that is generally cylindrical around a central axis (X), the inner wall extending parallel to the central axis between first (32) and second (34) substantially parallel faces, wherein the chamber (28) has an inlet opening (36) and an outlet opening (38). The collecting device also includes a rotor (40) which is rotatable around the central axis, and which includes at least three blades (41), each of which extend radially from a rotary shaft (42) to the inner wall (30) while defining, within the chamber (28), compartments (39) which are sized such that the inlet (36) and outlet (38) openings are in constant communication with separate compartments (39). The inlet opening is provided in the first base and the outlet opening is provided in the second base.

18. A collecting device for collecting particles, such as dust, designed to equip a device for purifying a gas by extracting particles, including:
-
a chamber, including an inner wall that is generally cylindrical around a central axis, said inner wall extending parallel to the central axis between first and second substantially parallel bases, the chamber having an inlet opening and an outlet opening, a rotor which is rotatable around the central axis, and which includes at least three blades, each of which extends radially from a rotary shaft to the inner wall while defining, within the chamber, compartments which are sized such that the inlet and outlet openings are in constant communication with separate compartments, wherein the inlet opening is formed in the first base, and the outlet opening is formed in the second base. - View Dependent Claims (19, 20, 21)

22. A purifying device for purifying a gas, such as air, by extracting particles, such as dust, including a collecting device, and at least one separating device for separating particles and gas, wherein:
-
the collecting device includes; a chamber, including an inner wall that is generally cylindrical around a central axis, said inner wall extending parallel to the central axis between first and second substantially parallel bases, the chamber having an inlet opening and an outlet opening, wherein the inlet opening is formed in the first base, and the outlet opening is formed in the second base, a rotor which is rotatable around the central axis, and which includes at least three blades, each of which extends radially from a rotary shaft to the inner wall while defining, within the chamber, compartments which are sized such that the inlet and outlet openings are in constant communication with separate compartments, each separating device includes; an inlet duct for gas charged with particles, a cleaned gas outlet duct, and an outlet duct for the particles arranged upstream from the inlet opening of the collecting device. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
