Abstract

See full text

A cover of a powder loading device prevents the escape of loose powder when the powder is transferred from a storage container of a plant to a receiving container. A blower inside the cover moves air from the outside, under the cover, a filter, and returns the filtered air to the outside. A backwash device is operated periodically to remove the filtered powder from the filter into the receiving container. The powder is delivered storage container to the receiving container through a retractable loading chute. A powder detection switch within the retractable loading chute determines when the receiving container is full and stops the transfer of powder. The result is a powder loading device which maximizes dust collection and minimizes lost loose powder. The powder loading device adapts to various plant and receiving container sizes.
