Abstract
The problem in picking up and collecting very fine dusts such as aluminum dust, cement and the like is to exhaust the transport air into the atmosphere without dusts. A sweeping machine which offers the solution to said problem comprises the following cooperating parts: a main mouthpiece (9) with at least one nozzle (10) blowing from the outside against the center of the mouth and a suction pipe (12) located inside; a secondary nozzle (15) with a suction conduit (17) movable with respect to the main mouthpiece (9); a common conduit (19) into which the two suction conduits (12, 17) open; a coarse separator (23) arranged in front of a cyclone multiple separator (24, 25, 26); a conduit (34, 35) supplying air from the cyclone on the suction side of a fan (3); a separation piece (4) on the exhaust side of the fan for dividing exhausted air and for supplying a portion of said air to the nozzle (10) blowing into the main mouthpiece (9) and the other portion to a separator (38); and an evacuation fan (45) arranged at the outlet of the separator (38).
