Compression and volume reduction treatment apparatus.

摘要

A compression and volume reduction treatment apparatus for solid wastes including a compression sleeve (4) for receiving therein a cylindrical vessel (20) filled with the solid wastes and a press ram (6) arranged above said compression sleeve (4) movably upward and downward for compressing at high pressure the cylindrical vessel in the compression sleeve (4). According to the invention, the compression sleeve comprises an upper straight large diameter portion (7a) a lower straight small diameter portion (7c) and an intermediate tapered portion (7b), thereby compressing the cylindrical vessel (20) and reducing its volume in three dimensional directions by compressing the vessel radially inwardly at the tapered inner surface of the intermediate tapered portion (7b) and compressing axially at the inner surface of the lower straight small diameter portion (7c) when the cylindrical vessel in said upper straight large diameter portion (7a) is urged by said press ram (6) in a uniaxial direction.
