Description

Technical Field

[0001] The utility model belongs to the technical field of ferrous sulfate processing, and in particular relates to a ferrous sulfate purification slag pulping device. Background Art

[0002] In recent years, lithium iron phosphate batteries have been rapidly applied and promoted in the fields of power and energy storage due to their safety, easy availability of raw materials, and high cost performance. According to relevant industry data, by 2030, the main raw materials of lithium iron phosphate will also usher in development opportunities. The iron source commonly used in the production of iron phosphate is generally selected from ferrous sulfate, a byproduct of sulfuric acid titanium dioxide, which is widely available and cheap. The ferrous sulfate generally complies with the corporate standards of titanium dioxide manufacturers: the content of ferrous sulfate heptahydrate is ≥85%, and the content of ferrous sulfate heptahydrate is ≥85%. i O2 content ≤ 0.5%, while the quality requirements of the upstream iron phosphate products in the lithium iron phosphate industry include conventional iron-phosphorus ratio, specific surface, compaction and other performance indicators, as well as clear indicators for the residual impurities such as Ti, Mn, and Zn in the products. It is difficult to solve these trace element indicator limit problems by relying solely on the iron phosphate production process. It should be positively controlled from the source, and ferrous sulfate must be purified.

[0003] In the process of ferrous sulfate purification, a certain amount of ferrous sulfate purification slag will be produced. In order to better recycle resources, the ferrous sulfate purification slag will be recycled.

[0004] When recycling the ferrous sulfate purification slag, the ferrous sulfate purification slag and water need to be mixed and slurried, so the corresponding ferrous sulfate purification slag slurrying device will be used. However, some existing ferrous sulfate purification slag slurrying devices still have certain shortcomings in actual use. Their functions are relatively simple. After slurrying the ferrous sulfate purification slag, a certain amount of sulfuric acid needs to be added for reaction and filtering. The common ferrous sulfate purification slag slurrying device is not convenient for cleaning the impurities in the reaction filtration, which reduces the overall operating efficiency and increases the operating burden on the staff.
