Description

Technical Field

[0001] This utility model relates to the technical field of aluminum fluoride preparation, specifically to a purification tank for aluminum fluoride preparation. Background Technology

[0002] Aluminum fluoride is mainly used in aluminum smelting to lower the melting point and improve the conductivity of electrolytes; it is used as an inhibitor of by-fermentation in alcohol production; it is used as a flux and component of ceramic and enamel glazes; and it can also be used as a solvent in the smelting of non-ferrous metals. Aluminum fluoride is an inorganic, colorless or white crystalline powder, insoluble in water, acids, and alkalis. It is stable, but hydrolyzes upon heating, and can be produced by the reaction of aluminum trichloride with hydrofluoric acid and ammonia.

[0003] Utility model patent CN221637379U discloses a purification tank for aluminum fluoride preparation, belonging to the technical field of aluminum fluoride preparation. It addresses the problems of existing technologies where the overall size of the device is large, operation is cumbersome, and feeding is difficult for personnel, resulting in poor practicality. The tank includes a fixed base on its lower right side, with a conveying cylinder on the upper end of the fixed base. A first motor is fixedly installed on the upper left side of the fixed base. A storage box is connected to the lower right side of the conveying cylinder via a first connecting pipe, and a feed inlet is provided at the upper end of the storage box. A bevel gear set is located inside the lower part of the conveying cylinder, with a screw conveyor at the upper end of the bevel gear set. The upper left side of the conveying cylinder is connected to the tank via a second connecting pipe. The first motor drives the bevel gear set to rotate, which in turn drives the screw conveyor to rotate. The material is injected into the storage box through the feed port and enters the conveyor cylinder through the first connecting pipe. During operation, the screw conveyor sends the material into the tank through the second connecting pipe, which realizes the feeding of materials and makes the feeding of materials more convenient.

[0004] However, the above patent still has shortcomings: although the patent can stir and mix aluminum fluoride melt, aluminum salt solution and fluoride salt, it does not have the function of adding aluminum fluoride melt, aluminum salt solution and fluoride salt in a certain proportion. Since the proportion of aluminum fluoride melt, aluminum salt solution and fluoride salt has a great impact on the purification of aluminum fluoride, the purification effect of aluminum fluoride is not good.

Since the proportion of aluminum fluoride melt, aluminum salt solution and fluoride salt has a great influence on the purification of aluminum fluoride, the purification effect of aluminum fluoride is not good.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 The present invention will describe the above technical solution in detail through the following embodiments:

[0026] A purification tank for preparing aluminum fluoride includes: a tank body 1; a fixed box 2 connected to the bottom center of the tank body 1; an input pipe 3 fixedly connected to one side of the top of the fixed box 2; storage boxes 4 on both sides of the fixed box 2; inlet ports 5 fixedly connected to the bottom of each storage box 4; the bottom of each inlet port 5 fixedly connected to the tank body 1; a stirring shaft 6 installed on one side inside the tank body 1; a metering mechanism 7 installed inside the fixed box 2 to control the addition of molten aluminum fluoride, aluminum salt solution, and fluoride salt in a certain proportion; and a stirring shaft 6 installed on the outer surface inside the tank body 1 to improve the mixing of molten aluminum fluoride and aluminum salt solution. The system includes a stirring mechanism 8 for mixing aluminum salts and fluoride salts. The user pours aluminum salt solution and fluoride salt into the storage tank 4. The aluminum fluoride melt enters the fixed tank 2 through the input pipe 3. After passing through the metering mechanism 7 inside the fixed tank 2, the aluminum fluoride melt enters the tank 1. While the aluminum fluoride melt is passing through the metering mechanism 7 inside the fixed tank 2, the aluminum salt solution and fluoride salt in the two storage tanks 4 are added in appropriate proportions according to the metering of the aluminum fluoride melt entering the tank 1. Then, the stirring mechanism 8 mixes the aluminum fluoride melt, aluminum salt solution and fluoride salt that enter the tank 1.

[0027] like Figure 2 , Figure 3 and Figure 5As shown, the metering mechanism 7 includes: a first rotating shaft 9 rotatably connected inside the fixed box 2, both ends of the first rotating shaft 9 passing through the fixed box 2 and extending to the feed inlet 5, the first rotating shaft 9 being rotatably connected to the feed inlet 5, and a transmission blade 10 fixedly connected to the outer surface of the first rotating shaft 9 inside the fixed box 2, the transmission blade 10 being adapted to the fixed box 2; a rotating wheel 11 fixedly connected to the outer surface of the first rotating shaft 9 near the feed inlet 5, an extension plate 12 fixedly connected to the top groove of the rotating wheel 11, a cylindrical block 13 fixedly connected to one side of the extension plate 12, a grooved wheel 14 meshing with the bottom of the rotating wheel 11, a second rotating shaft 15 fixedly connected to the center of the grooved wheel 14, the second rotating shaft 15 being rotatably connected to the feed inlet 5, and a metering wheel 16 fixedly connected to the outer surface of the second rotating shaft 15 inside the feed inlet 5, the top of the metering wheel 16 having a metering groove 17, the feed inlet 5 being respectively connected to the... The metering wheel 16 is adapted to the aluminum fluoride molten liquid. As the aluminum fluoride molten liquid enters the fixed box 2 through the input pipe 3, it drives the transmission blade 10 and the first rotating shaft 9 inside the fixed box 2 to rotate. The aluminum fluoride molten liquid enters the tank body 1. While the first rotating shaft 9 is rotating, it drives the rotating wheel 11. While the rotating wheel 11 is rotating, it drives the extension plate 12. The extension plate 12 drives the cylindrical block 13 to rotate. While rotating, the cylindrical block 13 is engaged in the grooved wheel 14 and drives the grooved wheel 14 to rotate 90 degrees. While rotating, the grooved wheel 14 drives the second rotating shaft 15. The second rotating shaft 15 drives the metering wheel 16. The metering wheel 16 drives the metering tank 17. When the first rotating shaft 9 rotates 4 times, the metering wheel 16 rotates once. Then, the aluminum salt solution and fluoride salt inside the metering tank 17 are put into the tank body 1 through the feed port 5, so as to control the proportion of aluminum fluoride molten liquid, aluminum salt solution and fluoride salt.

[0028] like Figure 2 and Figure 4As shown, the stirring mechanism 8 includes: a stirring shaft 6 located inside the tank 1 with several sets of stirring blades 18 uniformly fixedly connected to its outer surface; the top end of the stirring shaft 6 passes through the motor frame 19 and extends to the motor 20; the motor 20 is fixedly connected to the motor frame 19; the motor frame 19 is fixedly connected to the tank 1; and the stirring shaft 6 is fixedly connected to the output end of the motor 20. An auxiliary shaft 21 is provided on the side of the tank 1 away from the stirring shaft 6; the top end of the auxiliary shaft 21 passes through the tank 1 and extends to the outside of the tank 1; the auxiliary shaft 21 is rotatably connected to the tank 1; and several sets of auxiliary blades 22 are uniformly fixedly connected to the outer surface of the auxiliary shaft 21 located inside the tank 1, with the auxiliary blades 22 arranged in the opposite direction to the stirring blades 18. Furthermore, the auxiliary blade 22 and the stirring blade 18 are staggered. When the motor 20 is started, the output end of the motor 20 drives the stirring shaft 6 to rotate. While the stirring shaft 6 is rotating, it also drives the stirring blade 18. At the same time as the stirring shaft 6 rotates, the auxiliary shaft 21 also rotates synchronously. While the auxiliary shaft 21 rotates, it drives the auxiliary blade 22, so that the auxiliary blade 22 and the stirring blade 18 work together to stir and mix the aluminum fluoride melt, aluminum salt solution and fluoride salt. Since the auxiliary blade 22 and the stirring blade 18 are arranged in opposite directions, the aluminum fluoride melt, aluminum salt solution and fluoride salt mixture inside the tank 1 will generate convection, thereby improving the mixing efficiency and mixing of the aluminum fluoride melt, aluminum salt solution and fluoride salt.

[0029] like Figure 4 As shown, a first synchronous wheel 23 is fixedly connected to the top outer surface of the auxiliary shaft 21. The first synchronous wheel 23 is connected to a second synchronous wheel 25 via a synchronous belt 24. The second synchronous wheel 25 is fixed to the outer surface of the stirring shaft 6. The stirring shaft 6 drives the second synchronous wheel 25 while rotating. The second synchronous wheel 25 drives the first synchronous wheel 23 via the synchronous belt 24. The first synchronous wheel 23 drives the auxiliary shaft 21, so that the auxiliary shaft 21 and the stirring shaft 6 rotate synchronously.

[0030] like Figure 2 As shown, an annular heating plate 26 is fixedly connected inside the tank 1, which can heat the aluminum fluoride melt, aluminum salt solution and fluoride salt inside the tank 1, thus avoiding the situation where the temperature of the aluminum fluoride melt, aluminum salt solution and fluoride salt mixture is too low, causing the mixture to crystallize inside the tank 1.

[0031] like Figure 1 As shown, a control box 27 with an internal touch screen is fixedly connected to one side of the tank body 1, making it convenient for users to operate the device.

[0032] like Figure 1 and Figure 2 As shown, a discharge port 28 is provided at the center of the bottom of the tank 1. A valve 29 is provided inside the discharge port 28. The user can open the valve 29 to discharge the mixed liquid through the discharge port 28 to the outside of the device.

[0033] Working principle: The user pours aluminum salt solution and fluoride salt solution into the storage tank 4 respectively. As the molten aluminum fluoride enters the fixed tank 2 through the input pipe 3, it simultaneously drives the transmission blades 10 and the first rotating shaft 9 inside the fixed tank 2 to rotate. The molten aluminum fluoride also enters the tank body 1. Simultaneously, the first rotating shaft 9 drives the rotating wheel 11, which in turn drives the extension plate 12. The extension plate 12 drives the cylindrical block 13 to rotate, and the cylindrical block 13, while rotating, engages with the grooved wheel 14, causing the grooved wheel 14 to rotate 90 degrees. The grooved wheel 14, while rotating, drives the second rotating shaft 15, which in turn drives the metering wheel 16. The metering wheel 16 drives the metering groove 17, so that for every four rotations of the first rotating shaft 9, the metering wheel 16 rotates once, thus... The aluminum salt solution and fluoride salt inside the metering tank 17 are fed into the tank 1 through the feed port 5, thereby controlling the ratio of aluminum fluoride melt, aluminum salt solution, and fluoride salt. Based on the metering of the aluminum fluoride melt input into the device, the corresponding proportions of aluminum salt solution and fluoride salt are added, improving the accuracy of the ratio of aluminum fluoride melt, aluminum salt solution, and fluoride salt, and thus improving the purification effect of aluminum fluoride. This solves the problem that although the existing purification tanks for aluminum fluoride preparation can stir and mix aluminum fluoride melt, aluminum salt solution, and fluoride salt, they do not have the function of adding aluminum fluoride melt, aluminum salt solution, and fluoride salt in a certain proportion. Since the ratio of aluminum fluoride melt, aluminum salt solution, and fluoride salt has a significant impact on the purification of aluminum fluoride, the purification effect of aluminum fluoride is poor.

[0034] The motor 20 is started, and its output drives the stirring shaft 6 to rotate. While rotating, the stirring shaft 6 drives the stirring blades 18 and the second synchronous pulley 25. The second synchronous pulley 25 drives the first synchronous pulley 23 via the synchronous belt 24. The first synchronous pulley 23 drives the auxiliary shaft 21, causing the auxiliary shaft 21 to rotate synchronously with the stirring shaft 6. While rotating, the auxiliary shaft 21 drives the auxiliary blades 22, which work in conjunction with the stirring blades 18 to stir and mix the aluminum fluoride melt, aluminum salt solution, and fluoride salt. Since the auxiliary blades 22 and the stirring blades 18 are arranged in opposite directions, convection occurs in the aluminum fluoride melt, aluminum salt solution, and fluoride salt mixture inside the tank 1, thereby improving the mixing efficiency and mixing effect of the aluminum fluoride melt, aluminum salt solution, and fluoride salt.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
