Description

Liquid level regulator of electrolytic tank

Technical Field

Background

In the copper electrolysis production process, the anode plate generally uses two cathode periods, and the liquid level requirements of the electrolytic tank in the two cathode periods are different, mainly because the liquid level of the electrolytic tank is controlled to be higher in one period, the upper part of the anode plate is ensured to be fully dissolved, the utilization rate of the anode plate is improved, and the anode residue rate is reduced; entering a second period, and controlling the liquid level in the electrolytic tank to be as low as possible and 3-5 mm lower than the liquid level in the period in order to reduce the problem that the anode plate breaks at the end of the period and the anode plate falls off. Because the liquid level requirements of the first period and the second period are different, the liquid level of the electrolyte tank needs to be adjusted to adapt to the production requirement. In order to reduce residual crystallization on the upper part of the cathode copper, the liquid level in the electrolyte tank needs to be regulated to be 2mm higher for the day before the cathode copper is discharged from the tank at the end of the second period. For the electrolytic tank adopting the two-end overflow mode, in order to ensure that the liquid flow rates at the two ends of the electrolytic tank are equivalent, the flow rate in the electrolytic tank is uniform, and the overflow heights at the two ends are required to be regulated to be consistent. The adjustment of the liquid level is a frequent daily task in the copper electrolysis production process.

In order to improve the yield and the copper electrolysis production efficiency, more and more electrolysis workshops adopt a production mode with high current density and high flow, and when the circulation flow of electrolyte reaches 50 L.tank/min, an overflow port is extremely easy to splash, which is mainly caused by collision impact between liquid flowing downwards at high speed and gas diffusing upwards in a pipeline, as shown in fig. 4, for the copper electrolysis workshops adopting high circulation flow production. The splashed liquid is easy to burn surrounding production personnel, potential safety hazard is generated, a large amount of copper sulfate crystals are generated around the electrolytic tank, manual cleaning is needed, and the problem of splashing at an overflow port brings no small trouble to electrolytic production.
