Electrode element for electrolytic purposes and its use

An electrode element for an electrolysis cell for electrolytic precipitation of metals from a liquid containing metal ions, having

• a frame provided with parallel side sections (2, 3) of electrically insulating plastic,
• each element including at least one conduit (13) for supplying a liquid ion conductor and at least one conduit (16) for the removal of this liquid ion conductor, where
• at least one planar active part is disposed between said conduits to serve as an electrode (7), along which the ion conductor flows and where
• the active surface of the electrode (7) is covered by
• an ion exchange diaphragm (20),
• characterized in that
• said electrode element is used for partial dipping, up to an immersion line (17), in said liquid;
• the electrode (7) is removably supported in the side sections (2, 3) of the frame (1),
• that the diaphragm (20) is formed as a pouch enclosing at least the portion of the electrode (7) dipped into the metal-ion-containing liquid,
• the pouch is enclosed by a protective box (21) of an electrically insulating plastic provided with openings (22), where at least a portion of the openings (22) are directed toward an active surface of the electrode (7)
• and that
• the two side sections (2, 3) together with the lower strap (4) are defined at a periphery thereof by a pipe (13, 14) bent in a U,
• where one side section (2) is connected (13) at its upper end with the liquid supply.
