DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-7 In an embodiment of the present invention, a rapid stirring device for electrolytic manganese comprises a stirring tank 1, on the top of which is fixed a tank cover 9; a stirring motor 2 is fixedly mounted in the middle of the top of the tank cover 9, the output shaft of the stirring motor 2 passes through the bottom of the tank cover 9 and is connected to a stirring paddle 3 via a coupling;

[0030] Specifically, in electrolytic manganese production, the electrolyte contains multiple components, including manganese sulfate and sulfuric acid. Rapid stirring allows manganese ions (Mn2+) to be evenly distributed throughout the electrolyte. Without adequate stirring, the concentration of manganese ions can decrease rapidly near the electrodes, while being higher away from them, resulting in low electrolysis efficiency.

[0031] In this embodiment, the stirring motor 2 drives the stirring paddle 3 to stir the electrolytic manganese so that the manganese ions are evenly distributed throughout the electrolyte; through stirring, it can be ensured that there is always an adequate supply of manganese ions on the electrode surface, thereby maintaining a stable electrolysis reaction rate.

[0032] Furthermore, a locking sleeve 18 is fixed to the upper end of the stirring paddle 3, and the upper end of the locking sleeve 18 is connected to the cross-shaped rotating frame 6. Axles 7 are fixedly connected to the four corners of the cross-shaped rotating frame 6, and paddle blades 8 are fixedly mounted at the lower end of the axles 7. A rotating drum 4 is welded to the middle of the top of the cross-shaped rotating frame 6. The upper end of the rotating drum 4 is movably connected to the fixing sleeve 5 via a bearing, and the upper end of the fixing sleeve 5 is bolted to the bottom of the tank cover 9.

[0033] During electrolysis, if the electrolyte is static, the ion concentration near the electrode surface will rapidly decrease due to continuous consumption, forming a concentration gradient and leading to concentration polarization. Concentration polarization increases the electrolytic tank voltage, reduces energy efficiency, and may cause uneven deposition on the electrode surface.

[0034] By adopting the above technical solution, while the stirring paddle 3 rotates, the locking sleeve 18 can also drive the cross rotating frame 6 to rotate. The multiple shafts 7 and paddle blades 8 arranged on the outside of the cross rotating frame 6 can fully stir the electrolyte, increase the stirring range of the electrolyte, and enhance the stirring effect; it can effectively reduce the concentration difference between the electrode surface and the electrolyte body, reduce the degree of concentration polarization, and make the electrolysis reaction closer to the ideal state.

[0035] In this embodiment, the fixed sleeve 5 and the cross rotating frame 6 are both provided with an axial hole in the middle to facilitate the passage of the stirring paddle 3; the shaft 7 and the paddle blade 8 are installed in a mountain shape, wherein the outer edge of the paddle blade 8 is in contact with the inner wall of the stirring tank 1.

[0036] By adopting the above technical solution, the stirring paddle 3 and the paddle blades 8 cooperate to stir, so that the concentration of each substance in the electrolyte is uniform, and the stability of the environment in the entire electrolytic tank can be maintained; this is very important for ensuring the quality consistency of the electrolytic manganese, and avoiding uneven quality of the manganese deposit layer due to local concentration changes, such as local looseness and uneven impurity content.

[0037] In this embodiment, a medicine injection window 10 is further embedded at the upper end of the tank top cover 9 .

[0038] During the electrolysis process, some additives are often added, such as selenium dioxide, ammonium sulfite, etc. These additives need to be evenly dispersed in the electrolyte to play their role in improving the quality of electrolytic manganese and reducing the cell voltage.

[0039] In this embodiment, a liquid discharge pipe 13 is welded to one side of the lower end of the mixing tank 1 , and a flow sensor 14 and a butterfly valve 15 are connected in series to the liquid discharge pipe 13 .

[0040] The provision of the drain pipe 13 facilitates the discharge of the electrolyte. The flow rate of the discharged electrolyte can be monitored by the flow sensor 14. The provision of the butterfly valve 15 facilitates the opening and closing control of the drain pipe 13 during discharge.

[0041] In this embodiment, a guardrail 11 is welded to the upper end of the mixing tank 1, and a ladder 12 is welded to one side of the guardrail 11; the lower end of the ladder 12 is welded to the platform 17; and the platform 17 is welded and fixed to the base frame 16.

[0042] By adopting the above technical solution, the arrangement of the ladder 12 and the guardrail 11 facilitates the addition of additives during the electrolysis of electrolytic manganese.

[0043] The working principle of the present invention is as follows: the stirring motor 2 drives the stirring paddle 3 to stir the electrolytic manganese so that the manganese ions are evenly distributed throughout the electrolyte; through stirring, it is ensured that there is always an adequate supply of manganese ions on the electrode surface, thereby maintaining a stable electrolysis reaction rate; while the stirring paddle 3 rotates, the locking sleeve 18 can also drive the cross rotating frame 6 to rotate, and the multiple shafts 7 and paddle blades 8 arranged on the outside of the cross rotating frame 6 can fully stir the electrolyte, thereby increasing the stirring range of the electrolyte and enhancing the stirring effect; it can effectively reduce the concentration difference between the electrode surface and the main body of the electrolyte, reduce the degree of concentration polarization, and make the electrolysis reaction closer to the ideal state;

[0044] The coordinated stirring of the stirring paddle 3 and the paddle blades 8 makes the concentration of various substances in the electrolyte uniform, which can maintain the stability of the environment in the entire electrolytic tank; this is very important for ensuring the quality consistency of electrolytic manganese, and avoiding uneven quality of the manganese deposit layer due to local concentration changes, such as local looseness, uneven impurity content and other problems; the setting of the drain pipe 13 facilitates the discharge of the electrolyte, and the flow sensor 14 can be used to monitor the flow of the discharged electrolyte. The setting of the butterfly valve 15 facilitates the opening and closing control of the drain pipe 13 when discharging.
