Preventing dust release on discharge of bulk products - using hinged panels over storage area, closing automatically after discharge by action of springs or counterweights

摘要

A number of movable panels are arranged to form a barrier between the environment and the storage enclosure into which bulk products are discharged. Each panel is hinged along one of its sides to a fixed part of the enclosure and is held in the closed position by a spring or counterweight. When the products are discharged the panels open automatically under the weight of the products and then close when discharge is finished, trapping dust in the enclosure.
