Embodiment Construction

[0051] like Figures 1 to 5 As shown in the figure, a battery acid addition and formation system includes a three-layer structure distributed in sequence from bottom to top: a battery vacuum box 1, an acid pot vacuum box 2 and a quantitative acid addition system 3.

[0052] The battery vacuum box 1 is used to place the storage battery 6 to be processed, and has a first negative pressure system 17 for pumping negative pressure to 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 to connect external negative pressure 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 set in the battery vacuum box 1 . At least one...

Abstract

The invention discloses a battery acid adding and forming system, comprising: 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. The accumulator acid addition and chemical formation system of the present invention is divided into three layers, the bottom layer is the battery vacuum box for storing the battery, the middle layer is the acid pot vacuum box for the acid pot, and the upper layer is the part of the quantitative acid addition system The structure separates the battery from the acid pot and sets them on two separate floors. There is no acid mist in the battery vacuum box, which avoids corrosion problems such as battery terminals and connections, and keeps the battery dry. It can realize the synchronous acid addition of the storage battery, and keep the resting time of ionization after acid addition consistent; it can also realize the vacuum formation process.

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 slot and a battery cover that are covered with each other. The battery slot is generally divided into multiple cells, and a pole group is set in each cell. After the lead-acid battery enters the slot and the battery cover is closed , it is necessary to perfuse the electrolyte into the battery, and the electrolyte is a sulfuric acid solution, and then it is chemically formed. [0003] During the lead-acid battery formation process, the internal heat of the battery increases the temperature. Generally, water bath cooling or air cooling is 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 not to be too ...
