<p>A discharge apparatus of the present invention comprises a discharge drum (30) replacing one transportation drum in a drum train (17) of a filter attachment, transportation grooves (62) on a drum shell (43) of the discharge drum (30), jet holes (69,70) opening in the bottom of each transportation groove (62) so that the jet holes (69,70) of each two adjacent transportation grooves (62) open in different positions, a control sleeve (42) fixed in the drum shell (43), jet grooves (75,76) formed over a predetermined rotational angle zone ( theta 3) on the outer peripheral surface of the control sleeve (42) and connectable to their corresponding jet holes (69,70), blow pressure lines (79,80) for independently introducing a blow pressure into the individual jet grooves (75,76), and solenoid valves (81,82) arranged individually in the middle of the blow pressure lines and used independently to open and close the blow pressure lines (79,80). <IMAGE></p> |
