SOLID CONTENT COLLECTION APPARATUS AND SOLID CONTENT COLLECTION METHOD

摘要

A solid content collection apparatus which reliably prevents leakage of gas from a pressure filtration apparatus to a lower pressure side when collecting solid contents separated by the pressure filtration apparatus and reduces power expense. A discharger (22) used for the solid content collection apparatus (20) is provided with a two-shaft screw feeder (23) which carries wet cakes (C), a motor (24) which synchronously drives the two-shaft screw feeder (23), a solid content storage part (25) which stores the wet cakes (C) from the two-shaft screw feeder (23) as a consolidated layer to prevent the leakage of pressurized gas, a pressure opening/closing apparatus (26) which applies a predetermined pressure to an opening/closing body (26A) controlling the opening degree of the exit of the solid content storage part (25), to keep the consolidated layer within the solid content storage part (25), and an opening/closing control device (28) which controls the opening/closing operation of the opening/closing body (26A) of the pressure opening/closing apparatus (26).
