[0022] Example

[0023] Please refer to Figure 1-4 As shown, the utility model provides a technical solution: a metal lithium electrolytic cell device;

A guide tube 9 is fixedly mounted on the upper end of the tank body 1. This facilitates the stable installation of the partition 16, avoids displacement of the partition 16 during use, and affects the use effect, promotes the transmission of ions, improves the stability and reliability of the electrolytic cell, and improves production efficiency and purity;

[0025] The inner end of the mounting cover 2 is provided with a circular groove 10, and a circular ring 11 is mounted on the inner end of the circular groove 10, and a fixing bolt 12 is threadedly connected to the inner end of the circular ring 11, and a sealing ring 13 is tightly fitted to the lower end of the fixing bolt 12, and a mounting ring frame 14 is tightly fitted to the lower end of the sealing ring 13, and a clamping groove 15 is provided on the inner end of the mounting ring frame 14, and a partition net 16 is clamped and mounted on the inner end of the clamping groove 15. The fixing bolt 12 is threadedly connected to the inside of the mounting cover 2, and the fixing bolts 12 are arranged at equal angles in six groups at the inner end of the mounting cover 2. A gas pipe 17 is fixedly mounted on the upper end of the mounting cover 2. The upper end of the mounting ring frame 14 is clamped and mounted on the lower end of the mounting cover 2, and the mounting cover 2 is clamped and mounted with the sealing ring 13, so that the partition net 16 can be taken out for cleaning or replacement without changing the internal structure of the tank body 1, and the operation is simple and convenient.

[0026] Specific working principle:

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the metal lithium electrolytic cell device is used, when current passes through the cell body 1, lithium ions in the electrolyte move toward the cathode under the action of the electric field. On the cathode surface, the lithium ions obtain electrons and are reduced to metal lithium and deposited. At the same time, a corresponding oxidation reaction occurs at the anode. Through such an electrolysis process, the purpose of extracting metallic lithium from lithium-containing compounds is achieved. The partition 16 serves to separate the cathode and the anode and promote ion transmission. The mounting ring frame 14 has mesh holes for the partition 16 to contact the liquid, and the card slot 15 is provided to support the installation of the partition 16. After a period of use, dirt will accumulate on the partition 16, affecting its use. At this time, the fixing bolt 12 can be screwed out upward, and the annular member 11 can be taken out from the inside of the annular groove 10. After the sealing ring 13 loses its restriction, the sealing ring 13 is taken out from the inside of the annular groove 10. Because the sealing ring 13 is made of soft rubber, it is convenient to take out the sealing ring 13. At this time, the top of the partition 16 loses its restriction, and the partition 16 can be lifted up from the inner end of the card slot 15 for cleaning or replacement. The above completes a series of operations of the metallic lithium electrolytic cell device. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
