The electrolyte ton tank is a recyclable packaging item, also called electrolyte barrel, electrolyte tank, lithium battery electrolyte turnover barrel, etc.

The electrolyte has high requirements for the quality of the electrolyte tank, and the impurity requirements are parts per million. Therefore, in order to achieve the purpose of recycling the electrolyte barrel and ensuring the quality of the electrolyte, the electrolyte barrel must be cleaned to reduce the impurity content in the electrolyte barrel and prevent the electrolyte residue in the barrel from affecting the next batch of electrolyte. Affects the quality of the liquid.

　　In the past, most electrolyte tanks were cleaned with water, that is, the residual liquid in the electrolyte tank was first drained out, then the electrolyte barrel was disassembled, and high-purity water was used to rinse the various parts and barrels of the electrolyte barrel. The disadvantages of this water-washed electrolyte ton tank process are that it requires disassembling the electrolyte barrel for cleaning, which takes a long time, low bucket washing efficiency, high energy consumption and cost (it uses nitrogen, a large amount of high-purity water, and requires a drying room), and physical harm to employees. Large (the process of splitting the barrel will evaporate organic solvents).

　　The working mode of Changyuan stainless steel electrolyte ton tank cleaning production line is fully automatic operation, which can realize all-round scanning, cleaning and drying of closed containers and flanges. After running for multiple cycles, there are no dead spots in the cleaning of the container. All processes require only a few operators to be responsible for auxiliary work, inspection and monitoring outside the tank. Completely get rid of the safety hazards of manual cleaning and surrounding environmental pollution problems. Since the cleaning method uses water as the medium, a safe, environmentally friendly, corrosion-free, and damage-free cleaning process is achieved.
