An apparatus and related method for the recovery and the pneumatic transportation of dust coming from a filtration system provided with a particulate collection hopper. The apparatus comprises: an intermediate chamber for the passage of the particulate towards the evacuation means; and shutting means for a bottom opening (AP1) of said hopper. The apparatus is characterized in that the shutting means comprise, in turn, a shutter moved according to an arrow (ARW) by the action of intermittent pressurized air that flows in a control conduit forming part of said shutting means. Furthermore, the evacuation means comprise elements, specifically a nozzle aligned with a Venturi, to produce a pressure drop in the intermediate chamber. |
