ABSTRACT:
A particulate vacuum collector device comprises a generally closed housing 74 including a bottom portion 140 particulate material and air inlet 90 and an air outlet 84, the inlet and outlet being above the bottom portion and the air outlet being adapted to be connected with an air suction generator 40. A perforated drum 160 within the housing screens air flow between the inlet and the air outlet while particulate material gravity falls to the bottom portion. A particulate material outlet 220 is separate from the inlet and is associated with the bottom portion of the collector. An auger 210 is provided for conveying material from the bottom portion to the material outlet, such outlet including a door 224 which prevents air from entering the housing during start-up operation of the device and which, in conjunction with some material being conveyed to the outlet for discharge outside the device, creates an air lock to substantially prevent air entering the housing through the material outlet while material is being collected and discharged.
