DEVICE FOR ELECTROCHEMICAL TREATMENT OF INNER SURFACES OF METAL BOTTLES Russian patent published in 2003 - IPC

FIELD: electrochemical treatment of metals; devices for treatment of inner surface of metal bottles. SUBSTANCE: proposed device has working electrode made in form of closed cylindrical envelope which is placed inside bottle to be treated. Working surface of electrode is made from current-conducting fabric on base of carbon fiber; its outer side directed to surface to be treated is provided with insulating elements in form of nap of non-conducting fiber. Electrolyte supply system is made in form of tube provided with perforated blank whose outer surface is profiled according to bottom portion of bottle and is provided with dielectric limiters setting inter- electrode gap. Proposed device may be used for cleaning and treatment of gas pressure bottles under field conditions. EFFECT: enhanced efficiency. 4 dwg
