DETAILED DESCRIPTION

[0020] See also Figures 1 to 5In the embodiment of the utility model, a new type of liquid inlet device for an electrolytic cell includes an electrolytic cell 1 and a liquid inlet pipeline 2. The liquid inlet pipeline 2 is connected to a water distribution pipeline 4 located inside the electrolytic cell 1 through a water distributor 3. The bottom of the water distribution pipeline 4 is connected to liquid outlet pipes 5 that are evenly distributed and extend vertically downward. The liquid outlet end of the liquid outlet pipe 5 is close to the inner bottom wall of the electrolytic cell 1. The water distribution pipeline 4 is made of RPP material that is not easily corroded and deformed. When the device is installed during the electrolysis process, the neutral liquid used in the electrolytic cell and the selenium dioxide solution are formed into multiple points. It enters the electrolytic cell 1 and is evenly distributed, so that the cathode plate can be evenly replenished with new liquid, which speeds up the electrolytic manganese addition rate. The arrangement of the water distribution pipeline 4 plays a role of primary distribution, which improves the uniformity of distribution. The water distribution pipeline 4 is arranged near the bottom wall of the electrolytic cell 1. The output liquid impacts the bottom wall of the electrolytic cell 1 and then spreads outward, which improves the uniformity of distribution and avoids the concentration of liquid inlet. Under the action of the water distributor 3, the amount of liquid entering each water distribution pipeline 4 can be made the same, thereby improving the uniformity of liquid distribution.

[0021] In a preferred embodiment, evenly distributed water outlets are opened on the outside of the liquid outlet pipe 5, and the liquid in the liquid inlet pipeline 2 is horizontally sprayed out through the water outlets to mix with the electrolyte in the electrolytic cell 1. The bottom of the liquid outlet pipe 5 can also be sealed, and a water outlet is opened on the outside to spray the liquid horizontally and spread it outward.

[0022] In a preferred embodiment, upper curved arms 7 are provided at both ends of the water distribution pipeline 4, and the upper curved arms 7 are connected to the upper part of the water distribution pipeline 4. After the liquid enters the water distribution pipeline 4, it flows at the bottom inside the water distribution pipeline 4. The upper curved arms 7 are provided, and the liquid inlet pipeline 2 is connected to the neutral liquid pipeline 14 and the selenium dioxide pipeline 16 respectively through the three-way valve 15. The liquid inlet pipeline 2 is also connected to the air blowing pipeline 12. The air blowing pipeline 12 and the liquid inlet pipeline 2 are distributed with a one-way valve 13. The air blowing pipeline 12 increases the pressure in the water distribution pipeline 4. Air pressure, the air pressure inside the water distribution pipeline 4 increases, and the liquid located in the lower part of the water distribution pipeline 4 is pushed out, and the liquid remaining in the water distribution pipeline 4 can be pushed forward to avoid adding less or more neutral liquid and selenium dioxide solution. The one-way valve 13 prevents gas-liquid backflow and cross-flow. At the same time, after the liquid in the water distribution pipeline 4 is pushed out, gas remains in the water distribution pipeline 4. The one-way valve 13 prevents gas backflow, that is, maintains the air pressure in the water distribution pipeline 4, so the electrolyte and other liquids in the electrolytic cell will not enter the water distribution pipeline 4.

[0023] In a preferred embodiment, a docking end 8 is provided at the top of the upper curved arm 7, and a connecting pipe 10 and a connecting seat 11 are respectively provided on the left and right sides of the electrolytic cell 1, and the docking ends 8 at both ends of the water distribution pipeline 4 are respectively fixed to the connecting pipe 10 and the connecting seat 11, and the docking end 8 and the connecting pipe 10 are interconnected. The water distribution pipeline 4 is a later-installed technical improvement and is made of RPP material that is not easily corroded and deformed, and cannot be welded. Therefore, it is assembled through a detachable installation structure, which also provides convenience for subsequent maintenance and replacement.

[0024] In a preferred embodiment, a fixing shell 9 is provided on the outer side of the docking end 8 and the connecting pipe 10, the docking end 8 passes through the fixing shell 9 and extends to the inside of the connecting pipe 10 for threaded connection, the fixing shell 9 is fixed to the docking end 8 by bolts, and a pipe quick connector is provided at the end of the docking end 8, the docking end 8 is threadedly connected to the connecting pipe 10 through the pipe quick connector, the connecting pipe 10 is welded to the electrolytic cell 1, and the connecting pipe 10 is connected to the water distributor 3 through a compensation pipe 6.
