Abstract:
1. Apparatus for the recovery and pneumatic transportation of dust coming from a filtration system, the apparatus comprising a particulate collection hopper having a bottom opening evacuation means; an intermediate chamber for the passage of particulate towards the evacuation means; shutting means coupled to the bottom opening of said particulate collection hopper; a control conduit comprising opening/closing means for compressed air flow; and a port between the piston and the wall of the cylinder the port allowing seepage of the compressed air from the control conduit into the intermediate chamber; wherein said shutting means comprise air flow control means including a shutter displaceable by the action of pressurised air that flows in said air flow control means; wherein said evacuation means comprise means to produce a pressure drop in said intermediate chamber wherein the shutter is integral with a piston slidable along a wall in a cylinder; and wherein said shutting means is configured to cause a surface of the shutter to close the bottom opening of said particulate collection hopper when said air flow control means receives pressurized air.
