ABSTRACT:
The bulk material receiver and dispenser includes a hopper with a lower material outlet opening and an upper material and air inlet opening. The upper portion or "bonnet" of the hopper includes a pair of air passageways with a filter in each passageway, and a vacuum pump and valve are connected to the air passageways. When placed in operation, the vacuum pump induces a flow of air inwardly through one air passageway and out of the other passageway to back wash one of the air filters, and after a short time lapse, air is drawn through both air passageways to induce a flow of bulk material and air into the hopper. When a desired amount of bulk material has accumulated in the hopper, the other air passageway and filter are opened to the atmosphere and a stream of air from the atmosphere back washes the other filter.
