[0026] It should be noted that insufficient mixing in the existing preparation of sodium stannate will lead to residual organic impurities and pigments in the raw materials, affecting the purity of the sodium stannate solution and the subsequent crystallization process, which may affect the crystal growth and morphology. The uneven distribution of the raw materials will affect the synthesis reaction, resulting in a decrease in product uniformity and stability. Impurities attached to the surface of the crystal will reduce the purity of the product and affect its subsequent application performance. This solution ensures that the raw materials are evenly distributed and efficiently mixed in water to quickly generate a sodium stannate solution. At the same time, the addition of activated carbon effectively adsorbs organic impurities and pigments in the solution and improves the purity. The design of the spray head 15 realizes uniform cleaning of the sodium stannate crystals, removes surface impurities, maintains a wet state, and further improves the purity and quality of the product. These design features jointly optimize the preparation process, improve efficiency and reliability, and ensure the purity and quality of the final product.

[0028] After a certain amount of activated carbon is added into the first preparation chamber, the purpose of continuing stirring is to allow the activated carbon to fully contact with the solution, thereby effectively absorbing organic impurities and pigments in the solution to obtain a purer solution;

[0029] The sodium stannate solution to be generated passes through the first filter 3; the first filter 3 intercepts solid impurities in the solution and only allows clear sodium stannate solution to pass; the solid impurities are intercepted on the first filter 3, and the filtered solution continues to flow to the next stage; the sodium stannate solution preliminarily filtered by the first filter 3 flows onto the inclined screen 9 and flows downward. The design of the screen 9 can remove smaller impurity particles in the solution. These particles may be incompletely reacted raw materials, reaction by-products or other insoluble substances. The impurity particles on the screen 9 are intercepted and discharged through the slag discharge port 10.

[0030] In a further preferred embodiment of the present invention, Figure 5 As shown, the second preparation box 2 is provided with a

[0031] A second preparation chamber is provided with a connecting ring 11 in the second preparation chamber, a screening cylinder 12 is rotatably matched between the connecting ring 11 and the top side of the second preparation chamber, a second motor 13 is provided on the top of the second preparation box 2, and the output end of the second motor 13 is fixedly connected with the end key of the screening cylinder 12.

[0032] In this embodiment, the connecting ring 11 is an annular structure fixed inside the second preparation chamber, which is used to support and fix the screening cylinder 12. When the second motor 13 is started, it will drive the screening cylinder 12 to rotate in the second preparation chamber through a key connection. The rotation of the screening cylinder 12 can help the material to achieve the purpose of screening or separation.

[0033] In a further preferred embodiment of the present invention, Figure 2 As shown, a flow guide pipe 14 communicating with the second preparation chamber is disposed above the second preparation box 2 , and the flow guide pipe 14 extends to the top of the screening cylinder 12 and is connected to a spray head 15 .

[0034] In this embodiment, the guide tube 14 is connected to an external water source, and its function is to transport water from the external water source to the spray head 15, and the water is evenly sprayed onto the formed sodium stannate crystals. The design of the spray head 15 enables the water to evenly cover the surface of the crystal in the form of fine droplets, thereby achieving effective cleaning to remove impurities, unreacted materials or other unnecessary substances attached to the surface, thereby improving the purity of the product.

[0035] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a feeding port 16 is provided on the top of the first preparation box 1 , and a sealing cover 17 is hinged on the feeding port 16 .

[0036] In this embodiment, the feed port is an inlet for adding raw materials or water into the preparation box or reactor, so that the operator can easily add the required raw materials or water to the preparation process, thereby ensuring the continuity and stability of the production process. The main function of the sealing cover 17 is to ensure that the feed port 16 can remain closed when not in use to prevent the materials in the preparation box from being disturbed or contaminated by the external environment.

[0037] In a further preferred embodiment of the present invention, Figure 2 As shown, a heating block 19 and a temperature sensor 20 are disposed at the upper positions of the first preparation chamber and the second preparation chamber, and a display screen 21 electrically connected to the temperature sensor 20 is disposed on the outer sides of the first preparation box 1 and the second preparation box 2.

[0038] In this embodiment, the heating blocks 19 of the first preparation chamber and the second preparation chamber respectively assume different functions. In the first preparation chamber, the heating block 19 is mainly used to heat and concentrate the sodium stannate solution. By heating, the water in the solution gradually evaporates, so that the concentration of sodium stannate gradually increases, thereby achieving the purpose of concentration.

[0039] The heating block 19 of the second preparation chamber is used to perform a crystallization operation on the sodium stannate solution. When the concentration of the sodium stannate solution reaches a certain level, the sodium stannate in the solution begins to crystallize through the heat provided by the heating block 19. During the crystallization process, the heating block 19 continuously provides heat to help maintain the temperature of the solution and promote the growth and precipitation of sodium stannate crystals.

[0040] The temperature sensor (PT100) 20 sends the detected real-time temperature data to the display screen 21 in the form of an electrical signal. The operator can understand the current temperature status in the preparation chamber by checking the data on the display screen 21, thereby determining whether the heating process is proceeding normally or whether temperature adjustment is required.

[0041] In a further preferred embodiment of the present invention, Figure 2-3 As shown, a water pump 22 is arranged between the first preparation box 1 and the second preparation box 2, the water inlet end of the water pump 22 is connected to the lower position of the first preparation chamber through a water pipe 18, and the discharge end of the water pump 22 is connected to the upper position of the second preparation chamber through a water pipe 18, and the water pipe 18 extends to the upper part of the screening cylinder 12.

[0042] In this embodiment, the water pump 22 pumps the pure sodium stannate solution in the first preparation chamber into the second preparation chamber, which can achieve accurate feeding of the pure sodium stannate solution into the screening cylinder 12, thereby improving the efficiency of the production process and the product quality.

[0043] In a further preferred embodiment of the present invention, Figure 1-3As shown, a liquid discharge port 23 is provided at the lower position of the second preparation box 2 , and a material guide pipe 24 is connected to the liquid discharge port 23 .

[0044] In this embodiment, after the preparation process is completed, the liquid discharge port 23 and the material guide pipe 24 can be used to discharge the remaining solution or cleaning water to facilitate cleaning and maintenance of the equipment.

[0045] Working principle: When the device is used, raw materials containing tin elements, such as tin blocks, tin salts, etc., and an appropriate amount of water are added to the first preparation chamber of the first preparation box 1. Under the action of water, the raw materials begin to dissolve or undergo a preliminary reaction to form a solution containing tin elements. The first motor 5 is started, and the motor drives the first rotating rod 4 to rotate; the connecting rods 6 on both sides of the first rotating rod 4 rotate accordingly, and the scraper 7 on the outside of the connecting rod 6 rotates close to the inner wall of the first filter screen 3; the scraper 7 not only scrapes off the raw materials adhering to the inner wall of the first preparation chamber, but also plays a stirring role to ensure that the raw materials are evenly distributed in the water; the stirring and rotating actions promote the full reaction between the raw materials and water to generate a sodium stannate solution;

[0046] The heating block 19 in the first preparation chamber heats and concentrates the sodium stannate solution. By heating, the water in the solution gradually evaporates, so that the concentration of the sodium stannate gradually increases, thereby achieving the purpose of concentration. After uniform stirring, a certain amount of activated carbon is added to the first preparation chamber, and stirring is continued to allow the activated carbon to fully contact with the solution, thereby effectively absorbing organic impurities and pigments in the solution to obtain a purer solution;

[0047] After stirring and activated carbon adsorption, the generated sodium stannate solution passes through the first filter 3, which intercepts solid impurities in the solution and only allows clear sodium stannate solution to pass through. The solid impurities are intercepted on the first filter 3, and the filtered solution continues to flow to the next stage. The sodium stannate solution preliminarily filtered by the first filter 3 flows to the inclined screen 9. The design of the screen 9 can remove smaller impurity particles in the solution. These particles may be incompletely reacted raw materials, reaction by-products or other insoluble substances. The impurity particles on the screen 9 are intercepted and discharged through the slag discharge port 10;

[0048] The water pump 22 pumps the pure sodium stannate solution in the first preparation chamber into the second preparation chamber. When the second motor 13 is started, the screening cylinder 12 is driven to rotate in the second preparation chamber through a key connection. The rotation of the screening cylinder 12 can help the material to achieve the purpose of screening or separation. The heating block 19 of the second preparation chamber is used to perform a crystallization operation on the sodium stannate solution. When the concentration of the sodium stannate solution reaches a certain level, the sodium stannate in the solution begins to crystallize through the heat provided by the heating block 19. The guide pipe 14 is connected to an external water source, and the water from the external water source is transported to the spray head 15. The water is evenly sprayed onto the formed sodium stannate crystals to achieve effective cleaning and remove impurities attached to the surface.

[0049] After the preparation process is finished, the drain port 23 can be used to discharge the remaining solution or cleaning water, which facilitates the cleaning and maintenance of the equipment and ensures the smooth progress of the next preparation process.
