APPARATUS FOR DISCHARGING A THERMAL DECOMPOSITION RESIDUE CONTAINING CARBON RESIDUE AND BALLS OF STEEL WIRE

摘要

Apparatus for discharging a thermal decomposition residue containing carbon residue and steel wire balls, said discharge apparatus comprising: a discharge mechanism including a double shaft screw conveyor having the respective screws supported at one end thereof and located contiguously to a residue outlet of a thermal decomposition unit, and a housing hermetically connected to said residue outlet of said thermal decomposition unit and enclosing said double shaft screw conveyor with space on the upper side thereof; a first outlet provided in a bottom of said housing for discharging the carbon residue transferred by a lower portion of said double shaft conveyor; a second outlet provided at the free discharge end of said double screw conveyor for discharging the steel wire balls transferred by the upper portion of said double screw conveyor; a seal means provided in said first outlet for shielding the interior of said housing from the ambient atmosphere; and a water sealing means including a water bath and a chute connected to said second outlet at the upper end and opening into said water bath at the lower end thereof, and a conveyor for conveying the steel wire balls dropped into said water bath through said chute to a position outside said water bath.
