Abstract
An apparatus for unloading bulk materials from hopper-type rail cars and, more particularly, a pneumatic unloading apparatus or device incorporating a dual outlet for the pneumatically-actuated discharging of flowable bulk materials from the bottom of a hopper structure, and in which the bulk material is aspirated from the hopper structure into a pair of parallel conduits through spaced discharge orifices designed to minimize or eliminate any possible damage to the bulk material during the procedure of being conveyed therethrough.
Claims6
A pneumatic unloading apparatus for the discharge of a flowable bulk material from the bottom of a hopper;
- a trough-shaped housing connected to the lower end of said hopper, said housing having downwardly converging side walls and end walls, and a partition wall spaced between said end walls for separating said housing into a plurality of longitudinally spaced downwardly narrowing compartments;
- elongate slot-like orifices formed in the bottom of each said compartment, said orifices extending in parallel and being offset relative to each other at opposite sides of a longitudinal centerline extending through said housing, first and second parallel arranged conduits extending below said compartments on opposite sides of and coextensive with said longitudinal centerline, each said conduit having an opening means communicating with the respective orifice of the compartment on the same side of said centerline;
- and means for imparting a vacuum to each said conduit for aspirating bulk material from said hopper through the compartment and orifice associated therewith.
