Pulverfördervorrichtung und Verfahren zur Pulverauftragung auf einen Träger

摘要

The device has a powder container (12) with outlet connection (46) to feed power into a gas flow and with a gas flow connection device. The device connects a first gas flow (32) to the container to create a powder cloud (62) within the container. A second gas flow (40) is connected to the container to atomize the powder cloud. The outlet connection leads into an outlet tube (48) to remove powder from the powder cloud. The first gas flow is introduced in a direction mainly opposite to the direction of gravity, and passes through a powder barrier, e.g. a sintered plate (28), which is permeable to gas but impermeable to powder.
