Dust Screen and Method for Dry Bulk Storage Units
摘要:
A dust screen for an inspection hatch disposed in the roof or a side wall of a dry bulk storage unit for use during pneumatic loading of aggregate material from a pneumatic trailer via air pressure ducted into the bulk storage unit. The dust screen includes an elastic cord in a hem surrounding an open end of the screen to secure the dust screen to the inspection hatch. An alternative embodiment may include a binding strap having a ratchet buckle to supplement the elastic cord. As the dust screen extends upward in the presence of said air pressure, the dust is allowed to settle into the storage unit. No separate container to contain the dust is required, and no separate structure is required to support the dust screen during operation. The dust screen is light weight, portable and reusable, and low in cost.
