Abstract

A powder receiving device has a loading chamber with an integral dust collector. The dust collector preferably includes at least one bag filter which filters air taken from above powder loaded into the loading chamber. The filtered air is then fed either back into the loading chamber, into a hopper where the powder is released to an external location, or out over the container from which the powder is loaded. This air flow provides for increased fluidity of the powder. The bag filter is positioned facing the loading chamber, such that when a backwash mean sends a pulse of air into the bag filter, the collected powder is dropped back into the loading chamber. The resulting powder receiving device prevents powder from escaping when powder is transferred from a container into the loading chamber. Since the powder is prevented from escaping, the powder receiving device further provides a clean workplace.
