An electrolytic cell device for electrode foil formation

Abstract

The invention discloses an electrolytic cell device for electrode foil formation. The electrolytic cell device comprises a cell body (1). The cell body (1) is provided with a circulating inlet (2) and a circulating outlet (3). A circulating pipeline (4) is communicated between the circulating inlet (2) and the circulating outlet (3). The circulating outlet (3) is formed in the upper portion of the cell body (1). An impurity precipitation device (5) is arranged at the bottom of the cell body (1) and connected with the cell body (1), and a communicated cavity is formed. The impurity precipitation device (5) is in a funnel shape with a large upper opening and a sharp lower opening. A liquid discharge opening (6) is formed in the bottom of the precipitation device. An electrolyte for formation is located in the electrolytic cell device, crystalline particles and impurity particles in the electrolyte can be precipitated at the bottom of the conical cell body, crystalline particles and impurity particles in the circulating electrolyte are effectively reduced, the appearance quality of aluminum foil during electrode foil formation is improved, and the product yield is increased; and the production cycle of electrode foil formation can be prolonged, and production cost is reduced.

Description

technical field [0001] The invention relates to an electrolytic cell device for chemical formation in the production process of electrode foil. Background technique [0002] In the formation process of the electrode foil production process, the electrode foil is formed through the electrolytic cell containing the electrolyte, and the electrolyte containing the electrolyte needs to be circulated in the electrolytic cell. The purpose is to utilize the circulation pump, heater, heat exchanger, Sometimes a filter is installed to realize the circulation of the electrolyte in the electrolytic cell to keep the electrolyte circulation uniform and the temperature stable. The filter is installed to remove the crystallization and impurity particles in the electrolyte. [0003] Existing electrolyzer devices for electrode foil formation, such as figure 1 As shown, the device is a square tank, the bottom of the tank is a horizontal or inclined bottom, and the circulation inlet is at the ...

AI Technical Summary

Problems solved by technology

[0004] If the electrolytic cell of this device is not equipped with a filter, there will be many crystals and impurity particles during the production process. The extrusion of the electrode foil and the crystals or impurity particles will damage the appearance quality of the electrode foil and cause pits or cracks. In severe cases, the foil will be broken and affect The appearance quality of electrode foil products will reduce the yield and qualified rate of products. Even if a filter 11 is installed to filter crystals or impurity particles, it will be necessary to stop production for a certain period of time to clean and maintain the filter, which will greatly increase production costs. and production efficiency; at the same time, when the electrolytic cell is shut down to clean, because the bottom of the electrolytic cell is a horizontal bottom or an inclined bottom, it is difficult to clean the impurity particles, and multiple cleanings are required, which increases the cleaning cost and reduces the cleaning efficiency.
