Abstract:
A mechanism for isolating energetic material feed streams from a material processing apparatus through which energetic material moves from an upstream position to a downstream position toward the processing apparatus, said mechanism comprising:a material passage structure permitting movement of the energetic material downstream toward the processing apparatus; andflame deflecting structure constructed and arranged to allow the energetic material moving downstream to pass over said flame deflecting structure toward the material processing apparatus and to deflect flames which ignite within the material processing apparatus, to inhibit propagation of the flames to an upstream position past said flame deflecting structure, said flame deflecting structure including a deflector conduit, said deflector conduit comprising:side panels defining a material passageway having an entrance and an exit through which the energetic material moves from said entrance toward said exit, said side panels having openings formed therein; anddeflector baffles disposed within said material passageway and being positioned and oriented to permit the energetic material to move through the material passageway without falling through said openings and to deflect flames propagating into said passageway from said exit toward said entrance through said openings to substantially prevent the flames from reaching said entrance.
