Problems solved by technology

Because the acid-base neutralization reaction is fast, the acid in the positive plate migrates slowly to the water, and after soaking for a short time, the amount of acid in the positive plate migrates to the water is limited, and the cleaning effect of sulfuric acid in the positive plate is poor; if soaked for a long time, The positive plate is in a strong alkaline environment for a long time, and the active material PbO on the positive plate 2 reacts with NaOH to form Na 2 [Pb(OH) 6 ], causing adverse effects on the activity of the positive plate active material

Abstract

The invention discloses a low-maintenance storage battery positive plate cleaning and alkalizing device and a cleaning method and belongs to the technical field of storage batteries. The low-maintenance storage battery positive plate cleaning and alkalizing device is arranged on a storage battery plate cleaning tank, and comprises an alkali liquor containing barrel, an alkali liquor tank and an alkali liquor conveying pipe, wherein the alkali liquor containing barrel is inverted above the alkali liquor tank; the alkali liquor tank is arranged on the peripheral table board of the storage battery plate cleaning tank; the bottom surface of the alkali liquor tank is communicated with the alkali liquor conveying pipe; a control valve is arranged between the alkali liquor conveying pipe and the alkali liquor tank; and a group of liquid leakage holes is formed in the pipe wall of the alkali liquor conveying pipe. According to the device disclosed by the invention, the water consumption in the storage battery positive plate cleaning process is reduced, the cleaning time is shortened, the storage battery positive plate cleaning efficiency is improved, and the storage battery positive plate cleaning effect is improved.

Description

technical field [0001] The invention relates to a low-maintenance storage battery positive plate cleaning and adding alkali device and cleaning method, belonging to the technical field of storage batteries. Background technique [0002] Formation is an important process in the battery manufacturing process, which is the process of chemically and electrochemically reacting raw plates in sulfuric acid solution into cooked plates. Since the positive plate of the low-maintenance lead-acid battery still contains a certain amount of sulfuric acid after formation, it is easy to cause storage passivation problems and affect the starting performance of the battery. Therefore, it is necessary to clean the sulfuric acid in the positive plate after formation to ensure low maintenance. Stable battery storage performance. [0003] The existing positive plate cleaning method is: soak the positive plate with clear water, inject compressed gas into the clear water at the same time, and make...
