The present application provides the following embodiments.

[0023] As Figure 1 and Figure 2 As shown in the figure, it is a high-efficiency magnesium smelting vertical reduction tank structure schematic diagram of a preferred embodiment of the present application, the high-efficiency magnesium smelting vertical reduction tank of the embodiment comprises a reduction tank body 3, the bottom of the reduction tank body 3 is provided with a reduction slag discharge port 6, the center of the reduction tank body 3 is inserted with a center pipe 2, the bottom of the reduction slag discharge port 6 is detachably connected with a slag discharge port sealing cover 5, and the upper end of the reduction tank body 3 is detachably connected with a reduction tank sealing cover 1. In the embodiment, the material ball is added to the inside of the reduction tank body 3 by opening the reduction tank sealing cover 1, the reduction tank body 3 heats the material ball, the magnesium oxide and silicon inside the material ball react, magnesium vapor is generated under the catalytic action of calcium fluoride, and the magnesium vapor is crystallized after cooling. By pulling the center pipe 2 outward, the reduction slag can enter the inside of the reduction slag discharge port 6, and the reduction slag can be discharged by opening the slag discharge port sealing cover 5.

[0024] As Figure 1 and Figure 2As shown, this is a schematic diagram of the crystallization component structure in this embodiment. The outer wall of the reduction tank 3 near the bottom is detachably connected to a first crystallizer 9 and a second crystallizer 10. An opening is provided on one side of the first crystallizer 9 and the second crystallizer 10. A first crystallizer sealing cover 13 is detachably connected to the opening of the first crystallizer 9, and a second crystallizer sealing cover 14 is detachably connected to the opening of the second crystallizer 10. A crystallizer cooling water jacket 7 is provided on the outside of the first crystallizer 9 and the second crystallizer 10. In this embodiment, the negative pressure generated by the first crystallizer 9 and the second crystallizer 10 allows magnesium vapor to enter the interior of the first crystallizer 9 and the second crystallizer 10. The magnesium vapor inside the first crystallizer 9 and the second crystallizer 10 is cooled and crystallized by the crystallizer cooling water jacket 7 to form crude magnesium. By opening the first crystallizer sealing cover 13 and the second crystallizer sealing cover 14, the crude magnesium generated inside the first crystallizer 9 and the second crystallizer 10 can be taken out.

[0025] It is worth noting that the first crystallizer 9, the second crystallizer 10, the first crystallizer sealing cover 13, the second crystallizer sealing cover 14, and the crystallizer cooling water jacket 7 are crystallization components in this embodiment. The crystallization components include, but are not limited to, the first crystallizer 9, the second crystallizer 10, the first crystallizer sealing cover 13, the second crystallizer sealing cover 14, and the crystallizer cooling water jacket 7. Any component that can cool and crystallize magnesium vapor can be used in this embodiment.

[0026] like Figure 2 As shown, this is a schematic diagram of the closed assembly structure in this embodiment. A first vacuum valve 8 is detachably connected between the first crystallizer 9 and the reduction tank body 3, and a second vacuum valve 11 is detachably connected between the second crystallizer 10 and the reduction tank body 3. In this embodiment, when removing the crude magnesium from the first crystallizer 9, the first vacuum valve 8 is closed and the first crystallizer sealing cover 13 is opened to remove the crude magnesium from the first crystallizer 9. After removal, the first crystallizer sealing cover 13 is closed and the first vacuum valve 8 is opened, thereby allowing the interior of the first crystallizer 9 to continue cooling and crystallizing. When removing the crude magnesium from the second crystallizer 10, the first vacuum valve 8 is closed and the second vacuum valve 11 is opened. By closing the second vacuum valve 11 and opening the second crystallizer sealing cover 14, the crude magnesium inside the second crystallizer 10 can be removed. After removal, closing the second crystallizer sealing cover 14 and opening the second vacuum valve 11 will allow the interior of the second crystallizer 10 to continue cooling and crystallizing. While removing the crude magnesium from the first crystallizer 9 or the second crystallizer 10, the reduction reaction continues inside the other first crystallizer 9 or the second crystallizer 10. This allows the reduction reaction to continue while magnesium is being produced, unlike existing reduction tanks where the vacuum must be broken, the reduction reaction stopped, and the vacuum re-evacuated after magnesium is produced to allow the reduction reaction to continue.

[0027] It is worth noting that the first vacuum valve 8 and the second vacuum valve 11 are the closing assemblies in the embodiment, and the closing assemblies include but are not limited to the first vacuum valve 8 and the second vacuum valve 11, as long as the assemblies capable of closing or opening the first crystallizer 9 and the reducing tank body 3 and the second crystallizer 10 and the reducing tank body 3 can be applied to the embodiment.

[0028] As shown in Figure 1 and as shown in Figure 2 It is the structure diagram of the positioning assembly in the embodiment, and the outer wall of the center pipe 2 close to the center is detachably connected with the center pipe positioning plate 12, and the inner side bottom of the center pipe 2 is provided with an inclined surface inclined to the center. In the embodiment, the sliding of the center pipe 2 can be positioned by the center pipe positioning plate 12, and the inclined surface provided at the bottom can make the center pipe 2 and the center of the reducing tank body 3 block the slag outlet 6 and the reducing tank body 3 during the reduction after the center pipe 2 is pulled out.

[0029] It is worth noting that the center pipe positioning plate 12 is the positioning assembly in the embodiment, and the positioning assembly includes but is not limited to the center pipe positioning plate 12, as long as the assembly capable of positioning the center pipe 2 can be applied to the embodiment.

[0030] As shown in Figure 1 The outer wall of the slag outlet 6 is provided with the slag outlet cooling water jacket 4, and the slag outlet cooling water jacket 4 can cool the reduction slag in the embodiment, so as to facilitate the cleaning of the reduction slag.
