At present, the existing discharging device of the aluminum electrolysis material mixing vehicle usually only includes a simple discharging hopper and a discharging pipe structure, and many problems exist in the actual use process. Firstly, since the raw materials used in aluminum electrolysis production are mostly powdery or granular, blockage in the discharging pipe is likely to occur due to extrusion and agglomeration between the materials in the falling process, which causes the discharging to be interrupted, and the staff needs to clean frequently, which not only affects the production efficiency but also increases the labor intensity of the staff. Secondly, the existing discharging device cannot accurately adjust the discharging amount, and when the discharging amount needs to be changed according to different production conditions, it is difficult to achieve accurate control, which is likely to cause waste of raw materials or affect the normal progress of the electrolysis reaction. In addition, the outlet end of the discharging pipe is likely to be worn due to friction with the electrolysis tank or other equipment and the scouring of the materials in the long-term use process, and the discharging pipe needs to be replaced regularly, which increases the maintenance cost of the equipment.
