ABSTRACT:
A compression and volume reduction treatment apparatus for solid waste comprises a main compression and a pre-compression device. The main compression device includes a compression sleeve for receiving therein a cylindrical vessel filled with the solid waste and a press ram for compressing downward the filled cylindrical vessel. The pre-compression device comprises a pre-compression press ram and a pre-compression tapered sleeve for inserting the cylindrical vessel into the compression sleeve. The cylindrical vessel has an outer diameter larger than an inner diameter of the compression sleeve, while the pre-compression tapered sleeve has at a lowermost end an inner diameter smaller than the inner diameter of the compression sleeve. An inner circumferential surface of the pre-compression tapered sleeve and an outer circumferential surface of the pre-compression press ram are formed with grooves and ridges slidably fitted with each other. With such an arrangement, steel drums together with solid waste are compressed and reduced in volume to form a plurality of compressed blocks which can be stored in a steel drum which has the same size as that of the steel drum compressed together with the waste. An operator is only required to handle steel drums having the same size.
