[0022] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will combine the drawings in the present application to clearly and completely describe the technical solutions in the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0023] The embodiment provides an electrolytic cell, which comprises: a first U-shaped tube 1 and a second U-shaped tube 2, the second U-shaped tube 2 is sleeved outside the second U-shaped tube 2, and the height of the pipe opening of the second U-shaped tube 2 is greater than the height of the pipe opening of the first U-shaped tube 1, the outer wall of the pipe opening of the first U-shaped tube 1 is sealingly connected with the inner wall of the second U-shaped tube 2, the first U-shaped tube 1 is used for containing electrolyte, and the second U-shaped tube 2 is used for passing cooling medium to cool the first U-shaped tube 1.

[0024] In this way, by setting the height of the pipe opening of the second U-shaped tube 2 to be greater than the height of the pipe opening of the first U-shaped tube 1, and sealingly connecting the outer wall of the pipe opening of the first U-shaped tube 1 with the inner wall of the second U-shaped tube 2, even if the electrolyte overflows, it will also enter the part of the second U-shaped tube 2 that is higher than the first U-shaped tube 1, and then flow back into the first U-shaped tube 1, preventing the electrolyte from entering the cooling medium in the second U-shaped tube 2 below, effectively avoiding the occurrence of electrolyte overflow due to high solution reaction temperature in the first U-shaped tube 1, thereby avoiding the corrosion and pollution of the electrolyte to the hot chamber and other problems.

[0025] The first U-shaped tube 1 and the second U-shaped tube 2 described above can be processed from quartz glass, and the cooling medium is a cooling liquid.

[0026] As Figure 1As shown, the second U-shaped tube 2 is provided with a pair of interfaces 4, which are used to respectively enter and exit the cooling medium, and the interface 4 is located below the tube mouth of the first U-shaped tube 1. After the cooling medium enters the second U-shaped tube 2, it flows downward under the action of gravity, thereby preventing the cooling medium from entering the first U-shaped tube 1.

[0027] In this way, by setting up a pair of interfaces 4, it is possible to connect to a cooling system such as a circulating cooling system to continuously provide cooling medium to the second U-shaped tube 2, thereby achieving temperature regulation in the first U-shaped tube 1 and maximally cooling the solution in the first U-shaped tube 1.

[0028] In this embodiment, the first U-shaped tube 1 includes a first arc-shaped tube and a pair of first straight tubes, and the two ends of the first arc-shaped tube are respectively connected to the pair of first straight tubes; the second U-shaped tube 2 includes a second arc-shaped tube and a pair of second straight tubes, and the two ends of the second arc-shaped tube are respectively connected to the pair of second straight tubes; the second straight tube is sleeved on the outside of the first straight tube, and the second arc-shaped tube is sleeved on the outside of the first arc-shaped tube, and the curvature of the first arc-shaped tube and the second arc-shaped tube are the same; the bottom of the first straight tube is flush with the bottom of the second straight tube, the height of the pipe mouth of the second straight tube is greater than the height of the pipe mouth of the first straight tube, and the interface 4 is arranged on the second straight tube and is located below the pipe mouth of the first straight tube.

[0029] In some embodiments, the orifice of the second straight tube is 30-100 mm higher than the orifice of the first straight tube, that is, the height difference h between the orifice of the second U-shaped tube 2 and the orifice of the first U-shaped tube 1 is 30-100 mm. Preferably, the orifice of the second straight tube is 60-90 mm higher than the orifice of the first straight tube. Further, the orifice of the second straight tube is 65-74 mm higher than the orifice of the first straight tube, so that even if the electrolyte overflows the first U-shaped tube 1, it enters the second U-shaped tube 2, thereby avoiding pollution to the surrounding environment caused by the overflow of the electrolyte.

[0030] In this embodiment, the outer wall of the tube orifice of the first straight tube is sealedly connected to the inner wall of the second straight tube, that is, the outer wall of the tube orifice of the first U-shaped tube 1 and the inner wall of the second U-shaped tube 2 are sealed. Preferably, the outer wall of the tube orifice of the first straight tube and the inner wall of the second straight tube are welded together through a glass member 3. That is to say, glass is used as the welding material. Glass will soften and flow at high temperatures, thereby filling the gap between the outer wall of the tube orifice of the first straight tube and the inner wall of the second straight tube and forming a circle of seal, so that a sealed and reliable fixed connection is formed between the top end of the first U-shaped tube 1 and the second U-shaped tube 2, preventing the coolant from entering the first U-shaped tube 1.

[0031] like Figure 1 As shown, in some embodiments, the diameter of the first arc-shaped tube is smaller than the diameter of the first straight tube.

[0032] For example, the first arc-shaped tube has a tube diameter of 5-15 mm, and the first straight tube has a tube diameter of 30-70 mm; preferably, the first arc-shaped tube has a tube diameter of 8-13 mm, and the first straight tube has a tube diameter of 40-54 mm; further, the first arc-shaped tube has a tube diameter of 10-13 mm, and the first straight tube has a tube diameter of 45-54 mm.

[0033] The electrolytic cell provided by the utility model is not only suitable for common electrolytic reaction, but also suitable for electrolytic reaction involving radioactive elements.

[0034] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
