Abstract: A pulper includes a pulping chamber, a pulping mechanism, and a non-pulpas collection chamber attached to a bottom of the pulping chamber below a top of the pulping mechanism in an annular area outside of the pulping mechanism. The collection chamber includes a container with openings at first and second ends; a basket having an opening at a first end and disposed inside the container wherein at least a bottom portion of the basket includes perforations; a pipe connection located at the second end of the container; means for removing the basket from the container; and means for preventing material from entering a space between the basket and the container; wherein the first end of the container is inserted into the pulping chamber. The collection chamber does not interfere with the fluid flow around the pulping mechanism and can collect a relatively large amount of non-pulpables without requiring pulper shutdown.

Abstract: A solid waste pulper including a pulping chamber, oriented at an angle, hng a first inlet port for introducing solid waste material to be pulped, and a second inlet port in the pulping chamber for introducing water into the chamber. A blade assembly, preferably formed of a plurality of rotatable blades and a plurality of fixed blades, is mounted in the chamber for pulping the solid waste material introduced in the chamber, the water mixing with the pulped waste material to form a slurry. A sizing ring is provided in the pulping chamber through which the slurry must pass to be discharged, the sizing ring having a predetermined area for limiting the size of the pulped waste material in the slurry which can be discharged from the pulping chamber.

Abstract: A trash compactor is provided having at least a hollow compaction chamber rtically disposed on a base and a compacting ram slidaly fitted within the compaction chamber, such that the compacting ram is disposed above the trash to be compacted. The trash to be compacted is first loaded into the compaction chamber between the base and the compacting ram. A downward compaction force is then applied to the compacting ram to compact the trash within the compaction chamber to the required density. The downward compaction force is then maintained while the compaction chamber is removed from around the compacted trash. Finally, the downward compaction force is removed from the compacting ram thereby leaving a compacted trash slug. The trash may be wetted prior to compaction to further enhance the delamination characteristics of the trash slug.
