MACHINE FOR LOCALISED CLEANING WITH ELECTROLYTIC AND/OR ULTRASOUND CELL, FOR PICKLING AND/OR POLISHING

摘要

Machine for localised cleaning, including pickling acid or a composition/mixture of chemical elements with pickling action that is applied by hand or by mechanical instruments to the surface (5; 46; 64; 73) that is to be treated and also contains acid held in a limited quantity in the work position by a cell (1; 25; 35; 48; 65; 74) in material that will withstand the corrosive action of the acid; the cell is of the same volume (7; 47) as the acid used, i.e. it completely fills it with acid and reduces the volume to the volume of the acid contained in the perimeter of the cell projected on the surface to be treated; the acid is activated by the action of a device (11; 68) that activates pickling in its own device. Different constructional forms with electrolytic and/or ultrasound action are described together with aspiration and separation of fumes.
