摘要： The invention concerns a frame (1) to which a bag (2) of diaphragm fabric used in an electrolysis process is attachable and to the inside of said bag an anode plate (3) is adaptable. The frame (1) comprises a horizontal top beam (4) having a first end (5) and a second end (6), an upper side (7) and a lower side (8), the anode plate being sealably attachable in relation to the top beam at the longitudinal vertical middle plane of the top beam. A vertical first beam (9) having a first upper end (10) is connected to the first end (5) of the top beam. A vertical second beam (11) having a second upper end (12) is connected to the second end (6) of the top beam. The top beam (4) comprises a cavity (13) which opens downwardly and ex- tends along the length of the lower side (8) of the top beam. The invention also concerns an electrolysis system for electrowinning a metal from an electrolyte that contains a metallic salt. The system comprises electrolytic cells (20), each of said cells having means for keeping the electrolyte at a predetermined level (L). A number of anode plates (3) and cathode plates (21) are immersed in the electrolyte in an alternating and consecutive manner. Each anode plate (3) is arranged inside the frame (1) onto which a bag (2) of diaphragm fabric is attached to form an anode bag assembly (22. The cavity (13)in the top beam (4)collects pure oxygen generated on the anode plate during the electrolysis process.
