ABSTRACT:
A device for the discharge of bulk material (96) from a pressure vessel (2) is proposed, which comprises at least one sluice bin (24, 26) with a bottom (42, 44) and a top (40) sluice gate. The sluice bin (24, 26) is arranged under a plate (76, 76'), into which it forms an orifice (28, 30) for the bulk material (96). The top sluice gate (40) has a sealing plate (66), which is arranged above this plate (76, 76') in such a way that it can be positioned above the orifice (28, 30) of the sluice bin (24, 26) and, after a sealing connection to the edge of the orifice (28, 30) has been made, can be forced against this edge by overpressure in the pressure vessel (2).
