The present invention relates to a cleaning apparatus (100) for metal smallware, comprising: a washing chamber (1) apt to receive a solvent and at least one batch of metal smallware soiled with lubricant and configured to carry out a washing cycle to remove at least part of said lubricant from said batch of metal smallware soiled with lubricant by means of said solvent and; suction means (2) connected to said washing chamber (1) and configured to carry out a discharge cycle by sucking said gaseous mixture comprising air and solvent from said washing chamber (1); a main absorption column (4) having a first side (41) and a second side (42) opposite each other, and wherein said first side (41) is hydraulically connected to said suction means (2) so as to receive said gaseous mixture comprising air and solvent and said second side (42) is hydraulically connected to a supply duct (3) so as to receive an absorption liquid from the latter. In particular, the main absorption column (4) is configured to cause an interaction between a gaseous mixture supplied by said suction means (2) and an absorption liquid supplied by said supply duct (3) so as to perform chemical absorption of a solvent present in said gaseous mixture comprising air and solvent, in said absorption liquid, and therefore reduce the concentration of solvent in the gaseous mixture comprising air and solvent.
Cleaning apparatus (100) for metal smallware comprising:
Cleaning apparatus (100) according to any one of the preceding claims, comprising a stripper (8) connected to said washing chamber (1) so as to receive from said washing chamber (1) a liquid mixture comprising lubricant and solvent and configured to separate lubricant from solvent and where said stripper (8) is in fluid communication with said supply duct (3) directly or via said main supply tank (6), if provided, in order to supply said supply duct (3) and/or said main supply tank (6), if provided, with lubricant separated by the stripper (8) itself.
Cleaning apparatus (100) according to any one of the preceding claims, comprising a finishing absorption column (9) having a first end (91) and a second end (92) opposite each other, and wherein said first end (91) is connected hydraulically to said main absorption column (4) so as to receive said gaseous mixture and said second side (92) is connected to a finishing supply duct (10) so as to receive absorption liquid from the latter;
Method for cleaning metal smallware, intended to clean at least one batch of metal smallware soiled with lubricant, wherein said cleaning method comprises the following steps in succession:
