Liquid carbon dioxide dry cleaning system having a hydraulically powered basket

摘要

A liquid carbon dioxide cleaning system (20) for dry cleaning garments (19), comprises: (a) a pressurised vessel (12) containing a fluid bath (14) of liquid carbon dioxide. (b) a cylindrical basket (21) for holding the garments within the pressurised vessel. The basket having openings around the periphery. (c) roller bearings (22) positioned between the basket and the pressurised vessel inner surface to allowing the basket to rotate within the vessel. (d) manifolds (17) positioned between the pressurised vessel inner surface and the basket each having nozzles (15), aligned with the openings in the basket, that produce jets (13) of liquid carbon dioxide that agitate the garments. (e) a pump (18) coupled between the manifolds and the pressurised vessel for pumping the liquid carbon dioxide to produce the jets that both clean the garments and rotate the basket. Also claimed is a system with a second set of manifolds so that the direction of rotation of the basket can be changed.
