The difficulty for stocking and collecting dusts of aluminium, cement and similar is to return to atmosphere the transport air without dusts. A sweeper solving said problem has in combination the following parts: - a main mouth (9) with at least one nozzle (10) blowing from outside against the middle 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 mouth (9); - a common conduit (19) into which the two suction conduits (12, 17) open; - a coarse separator (23) arranged before 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 that air to the nozzle (10) blowing in the main mouth (9) and the other portion to a separator (38); and - an evacuation fan (45) arranged at the outlet of the separator (38). |
