AUTOMATIC LIQUID LEVEL CONTROLLER FOR ELECTROLYTIC CELL

摘要

PROBLEM TO BE SOLVED: To automatically adjust the liquid level of an electrolyte and to obtain electric copper having good styling by providing an outflow section communicating with an electrolytic cell with liquid drain piping which is open at the maximum liquid level and liquid drain piping which is open at a position lower than the lowest liquid level and has a stop valve. SOLUTION: A first liquid drain piping 11 and a second liquid drain piping 22 are communicated with the inside of a liquid drain box 3 communicating with an electrolytic cell 1. This liquid drain box 3 is segmented from the electrolytic cell 1 by a weir plate 2 for regulating the minimum liquid level L2 of an electrolyte 4 and the electrolyte 4 refluxes through the hole of this weir plate 2. An aperture of the first liquid drain piping 11 exists in the liquid drain box 3. This aperture is the maximum liquid level L1 of the electrolytic cell 1. The aperture of the second liquid drain piping 22 is arranged in the bottom within the liquid drain box 3. The second liquid drain piping 22 is provided with a stop valve 31 having an automatic control means in midway thereof. The stop valve 31 is periodically opened and closed. When the liquid level arrives at the middle of the V-shaped hole of the weir plate 2, the fall of the liquid level is stopped by balancing of the liquid feed and the liquid drain. This liquid level is the minimum liquid level L2.
