Description

Technical Field

[0001] The invention belongs to the technical field of formation activation, and in particular relates to a water temperature cooling monitoring mechanism for formation activation of a lead-acid battery. Background Art

[0002] During the production process of lead-acid batteries, the battery plates undergo a formation reaction, which can be divided into two types: external formation and internal formation. External formation means that the green plates are formed in the formation tank and transformed into mature plates. Its disadvantages are that a large amount of sewage, a lot of acid mist and high production cost are generated during the formation process; while internal formation means that the green plates are directly assembled into batteries, and electrolyte is injected into the battery for formation. Its advantages are that less lead-containing sewage and acid mist are generated during production, the production process is more environmentally friendly, and the battery production cost is low. However, its disadvantages are that after the battery is filled with acid, the dilute sulfuric acid and the lead oxide and other substances in the plates react chemically, and when the battery is charged and formed, a large amount of heat is released. The amount of dilute sulfuric acid will also be reduced due to chemical reaction and evaporation. The heat release will cause the internal temperature of the battery to rise sharply. If no cooling measures are taken, the temperature may even exceed 70°C. If no effective cooling treatment is performed, the lead solubility on the surface of the plate will increase, and excessive dissolution will easily cause the partition to penetrate and produce dendrite short circuit; excessive internal temperature of the battery will also cause the partition to turn yellow and degenerate, thereby affecting the quality and life of the battery; some lead-acid batteries will retain an acid filling pot on the battery during formation to replenish the reduced dilute sulfuric acid in the battery in time.

[0003] Therefore, cooling measures must be taken during the production process to ensure that the battery temperature rise is small and within the process requirements to ensure product quality requirements.

[0004] In the actual battery formation production, there are also great differences between the south and the north. Due to the low temperature in the north, even reaching sub-zero temperatures, the heat generated in the early stage of battery formation and charging is relatively large, and the cooling water temperature will increase to a certain extent. However, in the later stage of the formation stage, the heat generated by the battery is less, and the cooling water gradually approaches the ambient temperature. During the battery formation process, if the temperature is too low, the plate will not be completely formed, which will affect the battery consistency and life. The battery formation effect is better when the battery electrolyte temperature is controlled between 25°C and 45°C. Therefore, it is necessary to accurately monitor the water temperature in order to regulate the water temperature of the cooling water.

[0005] A Chinese utility model patent with publication number CN204289633U discloses a cooling water circulation system for internal formation of a lead-acid battery, comprising a battery cooling water tank, a water collecting tank connected to the battery cooling water tank via a water supply pipe, and a water temperature control system for adjusting the temperature of the cooling water in the water collecting tank. A drain port is provided at the bottom of the battery cooling water tank, and the drain port is connected to the water collecting tank via a return pipe. At least two water supply pipes connected to the water collecting tank are provided on one side wall of the battery cooling water tank, and an overflow pipe is provided on the opposite side wall, which is arranged in a staggered manner with the water supply pipe and is used to control the water level. The number of the overflow pipes is at least one more than the water supply pipe and is connected to the water collecting tank.

[0006] Although the cooling water circulation system for the formation of lead-acid batteries is provided with a temperature sensor for monitoring the temperature of the cooling water, rollers are generally provided in the existing formation cabinet for battery formation to facilitate the movement of the battery in the formation cabinet. The battery is placed on the rollers, and the cooling water submerges most of the battery. Since the rollers occupy a part of the space at the bottom of the formation cabinet, most of the heat released by the battery is concentrated in the upper part of the cooling water. If only the temperature of the upper part or the lower part of the cooling water is monitored, the water temperature monitoring of the cooling water will be incomplete, which is not conducive to water temperature regulation.
