Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid battery production, in particular to an acid solution preparation device for lead-acid battery production and processing. Background Art

[0002] A battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary. It is a device that converts chemical energy into electrical energy. The electrodes of a lead-acid battery are composed of lead and lead oxide, and its electrolyte is an aqueous solution of sulfuric acid. In the production process of lead-acid batteries, acid preparation is an extremely important step.

[0003] The patent document with application number CN202010968341.3 and titled "A device for preparing acid solution for battery production and processing" discloses a device capable of cooling the acid solution during the acid preparation process. When in use, cooling water is injected through the water inlet pipe on the circulating cooling connecting pipe assembly, and the cooling water enters the stirring branch pipe through the internal guide cavity of the mixing and stirring tube. When the mixing and stirring tube drives the stirring branch pipe to rotate, the acid solution in the acid solution preparation tank is simultaneously cooled and cooled. At the same time, the cooling water in the stirring branch pipe flows out through the reflux pipe into the water outlet pipe after being heated and then discharged, and the cooling treatment is continuously circulated, so that the acid solution is cooled and cooled synchronously during mixing and stirring. The device uses the stirring branch pipe of the rotating tube to stir the acid solution, and at the same time, the cooling water can circulate in the stirring branch pipe, so it plays a cooling role while stirring the acid solution. However, the structure of the device is complex, and the strength of the connection between the cooling branch pipe and the mixing and stirring pipe needs to be guaranteed, so the production requirements of the device are high and the cost is high.

[0004] The patent document with application number CN202121046281.6 and titled "A stirring type preparation device for acidic liquid for storage batteries" discloses an acidic liquid stirring type preparation device that can ensure the smooth flow of the configured liquid. The device is provided with an inner cavity on the side wall of the tank body, and a liquid inlet hole and a liquid flow hole are provided on one side of the inner cavity. The inner cavity is connected with the liquid inlet hole and the liquid flow hole, so that the inner cavity can circulate with each other, and the coolant can be injected into the inner cavity through the liquid inlet hole. When preparing, the heat released will be absorbed by the coolant in the inner cavity. When changing the coolant, the sealing plug inserted in the liquid flow hole can be pulled out to make the coolant flow out. However, only an inner cavity for accommodating the coolant is provided on the side wall of the tank body. When cooling the acidic liquid configured in the tank body, the cooling efficiency is low, and the configured liquid cannot be put into production quickly. Utility Model Content
