Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to an automatic cooling system for the internal formation of a lead-acid battery. Background Art

[0002] In the manufacturing process of lead-acid batteries, the formation process is a key process. Since the internal formation process eliminates the discharge of acid wastewater generated by tank formation in the production process of lead-acid batteries, the internal formation process is more environmentally friendly than the external formation process. Therefore, the internal formation process is gradually promoted and used in lead-acid battery production plants.

[0003] Lead-acid batteries generate heat during the internal formation process, which causes the battery's temperature to rise. Excessively high temperatures have a negative impact on the internal formation process, so the battery needs to be cooled during the internal formation process. Currently, a common practice is to immerse a portion of the lead-acid battery in a water tank to cool it. The water used to cool the battery flows through a cooler and then returns to the tank. Because many batteries are typically placed in a water tank for formation, such a tank is relatively long, requiring a large amount of water to cool the batteries. Relying solely on a cooler to cool the water in the tank requires higher specifications, resulting in high investment costs for the cooling system equipment used during the battery internal formation process.

[0005] Publication number is that a kind of automatic cooling system for forming in lead-acid battery is disclosed in the patent document of CN209675458U, the battery after the acid injection is sent to the formation slot by conveyor belt, the staff opens the formation slot door and builds on the conveyor belt frame, the slot door is placed with a transmission component, the battery is pushed into the formation slot by the transmission component, the roller in the formation slot is opened, the roller rotates and the battery is sent to the other end of the formation slot, a plurality of batteries are arranged side by side in the formation slot, after the formation slot is filled with batteries, the roller is closed, the slot door is closed, the controller switch is turned on, the first temperature sensor is inserted into a battery therein, the temperature in the battery is detected, the water level sensor detects the water level in the formation slot, and the formation slot is watered according to the water temperature and water level numerical value provided.Wherein, the second temperature sensor and the second water level sensor monitor the water temperature and the water level in the high water level pool, and when the water temperature in the high water level pool is higher than the limit of setting, the cooling box is opened, and the cooling water in the high water level pool is subjected to cooling treatment, until reaching the water temperature requirement. In this technical solution, when a cooling box is used to cool a large amount of water in a water tank, if a large amount of water in the water tank needs to be quickly lowered to a suitable temperature, the specifications of the cooling box need to be increased. Therefore, the investment cost of the cooling system equipment in the battery formation process is high. Utility Model Content
