Rotating cathode roll roller for electrolysis

The invention relates to a rotating cathode roll roller for electrolysis, which comprises an inner roller and an outer roller, wherein the inner roller is made of aluminum alloy, and mesh-shaped conducting plates are distributed on the inner surface of the inner roller; the wall thickness of the inner roller 2 is 12mm or 15mm; each conducting plate has the thickness a of 15mm or 20mm and the height c of 160mm or 200mm; each conducting plate comprises 6 annular conducting plates and 36 strip conducting plates; and an axial interval b of the annular conducting plates is 200mm, and the strip conducting plates are uniformly distributed at the inner roller in the circumferential direction. By the technical scheme of the invention, the conducting section area of the mesh-shaped conducting plates is larger than the axial conducting section area of the wall of the inner roller, and the resistance of the conducting plates is smaller than the axial resistance of the roller wall; the temperatureuniformity of the inner r
