A SYSTEM AND METHOD FOR UNLOADING BULK POWDER FROM LARGE BULK CONTAINERS

摘要

The present invention is directed to a system and a method to unload bulk powders from large bulk containers. The system and method are particularly useful for unloading bulk cohesive powders. The bulk unloading system comprises: a) a bulk container removably mounted on a platform, the container having surrounding walls (1) and a floor (3) mounted on a structural frame (4) and two ends, a front end and a rear end, wherein the front end is closed and rear end is partially open; and the platform having a means of tilting the container at an angle from about 0 to at least 40 degrees; b) optionally a removable, flexible liner within the container where the bulk powder is sealed; c) optionally vibrators mounted on the container floor structural frame; and d) a manifold having inlet (10) and discharge sections (11), the manifold being mounted on the rear end of the container or on the platform, wherein at least a portion of the manifold is lined with a pneumatic conditioning membrane (15) having a means of gas supply.
