Embodiment Construction

[0051] Such as Figure 1~5 As shown, a battery acid addition and chemical formation system includes a three-layer structure distributed from bottom to top: battery vacuum box 1, acid pot vacuum box 2 and quantitative acid addition system 3.

[0052] The battery vacuum box 1 is used to place the storage battery 6 to be treated, and has a first negative pressure system 17 that draws a negative pressure on the inner cavity of the battery vacuum box 1 during formation. The first negative pressure system 17 includes two pipelines, each tube A valve is set on the road, one of the pipelines is used for external negative pressure extraction equipment, such as an independent negative pressure fan or connected to the negative pressure pipeline of the entire workshop, and the other pipeline is used to open the inner cavity when needed. pressure. The air inlet of the first negative pressure system 17 can be arbitrarily arranged in the battery vacuum box 1 . At least one side of the batt...

Abstract

The invention discloses a storage battery acid adding and formation system, which comprises a battery vacuum box, an acid kettle vacuum box, an acid kettle arranged in the acid kettle vacuum box, a quantitative acid adding system and a mounting plate. According to the invention, the storage battery acid adding and formation system is divided into three layers, wherein the bottommost layer is the battery vacuum box used for containing the storage battery, the middle layer is the acid kettle vacuum box used for containing the acid kettle, the upper layer is the partial structure of the quantitative acid adding system, and the storage battery and the acid kettle are arranged in the two separated layers in a separated mode, so that no acid mist is generated in the battery vacuum box, the corrosion problem of storage battery terminals, connecting wires and the like is avoided, and the storage battery can be kept dry; synchronous acid adding of the storage battery can be realized, and the standing time at the beginning of ionization formation after acid adding is kept consistent; and the vacuum formation process can also be realized.

Description

technical field [0001] The invention relates to the technical field of storage battery production equipment, in particular to a storage battery acid addition and chemical formation system. Background technique [0002] The structure of the lead-acid battery includes a battery tank and a battery cover that are covered with each other. The battery tank is generally divided into multiple cells, and an electrode group is set in each cell. , It is necessary to pour electrolyte into the battery, the electrolyte is sulfuric acid solution, and then carry out chemical conversion. [0003] During the formation process of lead-acid batteries, the internal heat of the battery increases the temperature, and water bath or air cooling is generally used to cool down. At the same time, in order to control the formation temperature of the battery, it is necessary to control the charging current density so that it cannot be too large for a long time, resulting in low formation efficiency. On ...
