Air separation apparatus and system

A system for carrying out the air separation of waste having plastic categorized material, biodegradable categorized material and inorganic categorized material, comprising:

• conveyor means for receiving said waste material at a tail region thereof and continuously transporting said material forwardly and upwardly to a head region thereof, said material falling downwardly as a particle stream from the terminus of said conveyor at said head region;
• a housing having an input top wall portion extending over said conveyor terminus and a pair of mutually spaced first sidewall portions extending from said input top wall portion substantially adjacent said falling particle stream, said housing having plenum wall components and including an arcuate top wall portion extending from said input top wall portion substantially at said terminus level and coupled with a spaced pair of second sidewall portions to define a plenum;
• fan means for producing a stream of air at an outlet thereof, said outlet being positioned within said housing intermediate said first sidewall portions and spaced from and below said terminus;
• airstream guidance means for directing said fan means stream of air along a select direction toward said plenum substantially upwardly into lifting confrontation with said particle stream and toward said plenum arcuate top wall portion;
• means positioned intermediate said fan means outlet and said conveyor for restricting air flow therebetween;
• first outlet means positioned below the said level of said fan means and in substantial alignment with said terminus for receiving said inorganic categorized materials;
• second outlet means located adjacent said first outlet means and beneath said plenum for receiving said biodegradable categorized materials;
• third outlet means located adjacent said second outlet means and beneath said plenum for receiving said plastic categorized material;
• deflector means mounted within said housing plenum intermediate said second and third outlet means and extending toward said arcuate top wall portion for selectively adjusting the flow of air within said plenum and deflecting said biodegradable categorized material toward said second outlet means;
• means mounted upon said conveyor means for substantially removing static electrical charge from said material as is developed thereon by said conveyor means;
• and
• means defining openings within said plenum wall components for effecting air back pressure dissipation.
