Overflow type lead-acid storage battery formation water bath

The invention discloses an overflow type lead-acid storage battery formation water bath. The overflow type lead-acid storage battery formation water bath comprises a bath shell, a roll shaft, a water tank, a temperature controller, a valve, a leak-off pipe, a drainage exit, a heating pipe and a temperature sensor, wherein an overflow port is formed in the lower part at the middle position of the bath shell in a side wall length direction; the water tank is connected to the position of the overflow port of the bath shell in a sealing manner; an opening of the water tank is upward to form a container communicating with the inner cavity of the bath shell; the water tank is internally provided with the vertically arranged leak-off pipe; a pipe opening in the upper end of the leak-off pipe uses the opening of the water tank as an upper limit; and a pipe opening in the lower end of the leak-off pipe passes through a base plate of the water tank and is directly connected to the drainage exit to form a leakage flow passage. The temperature controller is controlled by the temperature sensor, and the water temperature is adjusted by adjusting the opening of a hot water inlet or a cold water inlet at random. The storage level and water temperature inside the overflow type lead-acid storage battery formation water bath are controllable, the overflow type lead-acid storage battery formation water bath is simple in structure and high in degree of automation, constant water temperature is beneficial for improving formation quality, and the labor intensity of operators at the posts can be alleviated, so that the production efficiency is obviously improved.
