Discharge device, for material from a pyrolysis plant

摘要

Discharge device has a casing (1) into which runs a discharge pipe (2) from a carbonising drum. There are outlets (3,6,5) for carbonisation gas, bulky residues and fine residues. Below the mouth of the discharge pipe there is a bar screen (4) in the casing which may be moved, and which covers the fine material outlet (5). The screen is inclined towards the bulky material outlet (6) and ends there. There is a vibrator (10) to move the bar screen (4) outside the casing which is attached to the screen by a plunger (11) running through a gas and dust tight opening.
