Description

Technical Field

[0001] The utility model belongs to the technical field of gallium-containing solution treatment, and in particular relates to a comprehensive gallium-containing solution treatment device. Background Art

[0002] Gallium, a rare metal, has demonstrated broad application potential in high-tech fields due to its unique physical and chemical properties. It is not only a key raw material for the manufacture of high-performance semiconductor materials, but also plays an irreplaceable role in solar cells, fiber-optic communications, superconducting materials, and aerospace. However, the natural abundance of gallium is extremely low, and it typically exists as compounds in various ores and wastewaters. Therefore, processing equipment is required to efficiently and purely extract gallium from gallium-containing solutions.

[0003] However, in the process of treating gallium-containing solutions, it is usually necessary to add reactants such as sodium sulfide and nickel chloride for mixing reaction. The current treatment method is usually to introduce the gallium-containing solution and all reactants into a reaction tank at the same time, which will cause the reactants to accumulate at a fixed position on the gallium-containing solution. During stirring, it will make it difficult for the reactants to be quickly dispersed into the gallium-containing solution and mixed. Generally, a long stirring time is required to achieve uniform mixing, which reduces the mixing effect. Therefore, the applicant proposes a comprehensive gallium-containing solution treatment device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a comprehensive gallium-containing solution treatment device, which aims to improve the current treatment method, which usually introduces the gallium-containing solution and all reaction materials into a reaction tank at the same time, causing the reaction materials to accumulate at a fixed position on the gallium-containing solution. During stirring, it is difficult for the reaction materials to be quickly dispersed into the gallium-containing solution for mixing. Generally, a long stirring time is required to achieve uniform mixing, which reduces the mixing effect.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] The processing mechanism includes a processing tank fixedly mounted on the top of the base, wherein a stirring chamber and a static chamber are respectively opened inside the processing tank, and the static chamber is located at the bottom of the stirring chamber;

[0009] The premixing mechanism includes a static box fixedly installed on the top of the processing tank and a premixing tube fixedly connected to the outside of the processing tank.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The present invention is provided with a pre-mixing mechanism, which can utilize a still box to store the gallium-containing solution. By introducing reactants such as sodium sulfide and nickel chloride into the still box, the pre-mixed gallium-containing solution can be introduced into a pre-mixing tube. The pre-mixing tube is annular, which can enable the pre-mixed gallium-containing solution to flow along the shape of the pre-mixing tube, effectively dispersing the sodium sulfide and nickel chloride into the gallium-containing solution for pre-mixing, thereby increasing the subsequent mixing speed in the stirring chamber and effectively reducing the stirring and mixing time in the stirring chamber.

[0026] 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.

[0027] Example 1:

[0028] See also Figures 1-6 As shown, a comprehensive gallium-containing solution processing device includes:

[0029] A base 4 and a processing mechanism 2 mounted on the top of the base 4, a premixing mechanism 1 mounted on the processing mechanism 2, a filtering mechanism 3 mounted on the bottom of the processing mechanism 2, and an electrolytic cell 5 mounted on the top of the base 4 and corresponding to the filtering mechanism 3;

[0030] The processing mechanism 2 includes a processing tank 21 fixedly mounted on the top of the base 4. The processing tank 21 has a stirring chamber 22 and a static chamber 23 respectively opened inside. The static chamber 23 is located at the bottom of the stirring chamber 22.

[0031] The premixing mechanism 1 includes a static box 11 fixedly mounted on the top of the processing tank 21 and a premixing tube 12 fixedly connected to the outside of the processing tank 21. A delivery pipe 13 is connected between the bottom of the premixing tube 12 and the stirring chamber 22, and the delivery pipes 13 are distributed in a ring array.

[0032] Depend on Figure 3 It can be seen that a motor 27 is fixedly installed on the top of the processing tank 21 , and the output shaft of the motor 27 extends into the stirring chamber 22 and is fixedly connected to a stirring rod 26 .

[0033] As can be seen from the above, in the process of treating the gallium-containing solution, the gallium-containing solution is introduced into the static box 11 for storage, sodium sulfide and nickel chloride are added into the static box 11, and then the mixed solution of the gallium-containing solution and the sodium sulfide and nickel chloride is introduced into the premixing tube 12. The mixed solution can flow along the annular channel of the premixing tube 12, so that the sodium sulfide and nickel chloride can be dispersed into the gallium-containing solution for premixing, which can increase the subsequent mixing speed in the stirring chamber 22 and effectively reduce the stirring and mixing time in the stirring chamber 22. The mixed mixed solution can be introduced into the stirring chamber 22 by using the conveying pipe 13. Since the multiple conveying pipes 13 are arranged in an annular shape, the mixed solution can be evenly introduced into the stirring chamber 22, which is beneficial to the mixing of the gallium-containing solution and the mixing of the gallium-containing solution. The motor 27 can drive the stirring rod 26 to rotate, so that the rotating stirring rod 26 can collide and impact with the introduced mixed liquid, and the mixed liquid can be beaten and dispersed, and the mixed solution can be made to fall in a raindrop-like manner, so that the gallium-containing solution can be uniformly and quickly mixed with the sodium sulfide and nickel chloride. After being stirred by the stirring rod 26 for 1 to 2 hours, the mixed gallium-containing solution can be introduced into the standing chamber 23 and stood for 8 to 12 hours. After standing, the gallium-containing solution is introduced into the filtering mechanism 3 to remove insoluble impurities to obtain a filtrate. By introducing the filtrate into the electrolytic cell 5 for electrolysis to extract metallic gallium, it is convenient to carry out an integrated process without the need to transfer it to other equipment for processing operations, thereby reducing the processing time and improving the processing efficiency.

[0034] Specifically, regarding the above-mentioned filtering mechanism 3, refer to Figure 1 、 Figure 4 and Figure 6 As shown, the filtering mechanism 3 includes a filter tank 31 fixedly installed at the bottom of the treatment tank 21. The filter tank 31 is connected to the treatment tank 21 through an input pipe 32. A filter element 33 is fixed to the internal limit of the filter tank 31. A sealing cover 34 is threadedly connected to one side of the filter tank 31. One side of the sealing cover 34 is connected to an output pipe 35 extending into the electrolytic cell 5.

[0035] As can be seen from the above, a control valve is provided on the input pipe 32, which can allow the gallium-containing solution after standing to be introduced into the filter tank 31. The impurities in the gallium-containing solution can be intercepted and filtered through the filter element 33, so that the filtered gallium-containing solution can be discharged into the electrolytic cell 5 through the output pipe 35 for electrolytic processing operation. By rotating the sealing cover 34, the sealing cover 34 can be easily disassembled, and the staff can easily replace the filter element 33 to ensure the filtering effect of the gallium-containing solution.

[0036] For details about the above, refer to Figure 2 As shown, the top of the static box 11 is connected to a feed port 15 , and a conduit 14 is connected between one side of the static box 11 and the top of the premixing tube 12 .

[0037] As can be seen from the above, the gallium-containing solution, sodium sulfide and nickel chloride can be conveniently introduced into the still box 11 for temporary storage through the feed port 15. The solenoid valve provided on the conduit 14 can enable the gallium-containing solution in the still box 11 to be introduced into the premixing tube 12, so as to facilitate the premixing operation of the gallium-containing solution with sodium sulfide and nickel chloride.

[0038] Example 2:

[0039] refer to Figure 3 As shown, a diversion pipe 25 is fixedly installed on the outside of the processing tank 21, and the diversion pipe 25 is communicated with the stirring chamber 22 and the static chamber 23 respectively.

[0040] As can be seen from the above, a control valve is provided on the diverter tube 25, which can be used to switch the diverter tube 25, and can guide the mixed liquid stirred in the stirring chamber 22 into the still chamber 23 for still operation.

[0041] Preferably, reference Figure 1 and Figure 3 As shown, support legs 24 are fixedly installed between the outer side of the processing tank 21 and the base 4, and the support legs 24 are distributed in a circular array.

[0042] As can be seen from the above, the supporting legs 24 can stably support the processing tank 21, thereby preventing the processing tank 21 from shaking during operation.

[0043] Preferably, reference Figure 1 and Figure 6 As shown, an anode tube 51 and a cathode tube 52 are fixedly installed inside the electrolytic cell 5 , and a discharge pipe 53 is connected to one side of the electrolytic cell 5 .

[0044] As can be seen from the above, by introducing the filtered gallium-containing solution into the electrolytic cell 5, the current generated by the anode tube 51 and the cathode tube 52 can be used to electrolyze the gallium-containing solution, thereby facilitating the extraction of metallic gallium. The material can be easily discharged through the discharge pipe 53, making it convenient for the staff to perform collection operations.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
