Abstract

The utility model relates to an electrolytic copper foil production technology, in particular to a constant temperature control device for an electrolytic copper foil additive tank, an additive tank body is arranged in a double-layer mode, the inner layer is an additive solution preparation tank, the outer layer is a steam condensate water return circulation heat preservation tank, and an electric stirrer and a feeding port used for adding pure water and an additive are arranged at the top of the additive tank. The bottom of the tank body is provided with an additive liquid outlet and a tank body support, the bottom of the outer-layer tank body is provided with a steam condensation return water inlet and a pneumatic valve used for automatically regulating and controlling the return water flow according to the temperature detected by the temperature sensor, and the top of the outer-layer tank body is provided with a steam condensation return water outlet. According to the utility model, on one hand, secondary utilization of steam condensate water is realized, on the other hand, the problems of deterioration, low dissolving efficiency and the like caused by inconstant temperature of an additive are avoided, and meanwhile, the return water temperature can be automatically adjusted through the pneumatic valve, so that the work of manual temperature control is greatly reduced.
