Abstract
A method and apparatus for controlling dust generated by the rotary dumping or rail cars may include one or more flexible baffles are provided to the back-side of a rotary dump frame to seal a portion of the material receiving pit during a portion of the rotary motion. The dust cloud generated by this dumping is retained in the pit for an increased time due to tumbling of the cloud induced by the baffles and other features of the facility. A plurality of intake ducts removes the dust cloud from the pit for transfer to a remote filtering facility.
Claims9
An apparatus for rotary dumping of rail cars, comprising:
- a dumping facility having an interior and an exterior;
- a material receiving pit disposed within the interior of the dumping facility, the pit defining an inside surface having a dump side, a back side and a bottom;
- a rotational frame disposed in the pit, the frame configured to dump a load from a rail car as it travels along a rotational path of travel between an upright position wherein the entire load is in the rail car and a dumping position wherein the load exits the rail car;
- one or more dump side baffles operably connected to a dump side hood, the one or more dump side baffles disposed at least partially within the pit;
- a backside airflow diverter disposed within the pit adjacent the back side of the pit, wherein the backside airflow diverter includes an upper surface and a lower surface,
- a backside hood for removing contaminated air from the back side of the pit;
- and
- one or more flexible baffles disposed on the rotational frame, the one or more baffles presenting a leading edge, and the one or more baffles configured to contact the backside airflow diverter during at least a portion of the rotational motion.
