Abstract
The invention concerns a device for separating and collecting waste driven by an air stream, comprising an intake duct (52) emerging along a tangential direction in a waste separating chamber (53) defining an internal volume having substantially the shape of a cylinder, in the central part of said chamber (53) is arranged at least an opening (61, 63) emerging onto a duct connected to a suction unit, said chamber (53) having a channel (68) for evacuating waste along a radial direction, said channel (68) being connected to a sealed pan (76) collecting centrifuged waste, the air intake channel (52) and the waste evacuating channel (68) being arranged substantially at the same height in the waste separating chamber (53). The invention is characterized in that the diametrical section of the chamber (53) ranges between twice and ten times the smallest cross-section of the channel carrying waste from the nozzle.
