Description

Technical Field

[0001] This invention relates to the field of high-purity aluminum purification technology, and in particular to a high-purity aluminum vacuum purification device and its purification process. Background Technology

[0002] High-purity aluminum typically refers to aluminum materials with a purity of not less than 99.99%, and can be further subdivided into sub-ultra-high purity aluminum, ultra-high purity aluminum, and extremely high purity aluminum. With its low deformation resistance, high electrical conductivity, good plasticity, and excellent chemical stability, it plays an irreplaceable role in various fields such as electronics, aerospace, optics, new energy, and high-end scientific research. In the electronics industry, high-purity aluminum is used as conductors for integrated circuits, sputtering targets, and key aluminum foil for electrolytic capacitors. In the aerospace field, it serves as a core raw material for lightweight components, balancing strength and weight requirements. In the optics and new energy fields, its coatings can be used in telescopes and laser equipment, and it is also an important material for lithium-ion battery current collectors. In high-end scientific research, it can also be used as a substrate for superconducting materials, a coolant for nuclear reactors, and other special-purpose materials.

[0003] With the rapid development of high-end manufacturing and technology, the market's requirements for the purity of high-purity aluminum are constantly increasing, and the demands for product quality stability and consistency are becoming increasingly stringent. However, aluminum in nature exists primarily in compound form, and the purity of primary aluminum obtained through conventional smelting is insufficient to meet the needs of high-end applications. Therefore, high-purity aluminum purification technology has become one of the core focuses of the industry's development. Currently, internationally mature high-purity aluminum purification technologies mainly include the three-layer liquid electrolysis method and the segregation method. Among them, the segregation method, due to its advantages such as power saving, low energy consumption, and environmental friendliness, has gradually become a hot topic in industry research and application. Its core principle is to utilize the difference in solubility between aluminum and impurity elements in the molten state and the segregation characteristics during the solidification process to achieve the separation and purification of impurities from aluminum.

[0004] Typical high-purity aluminum vacuum purification equipment has a low degree of automation and relies heavily on manual operation to switch and control each process.

[0015] A high-purity aluminum vacuum purification process according to the present invention includes:

[0016] In the initial state, the second lifting component drives the segregation disk in the closed position, sealing the connection between the segregation channel and the hot-melt crucible;

[0017] The electromagnetic heating coil transfers heat to the hot-melting crucible. As the temperature rises, the solid aluminum material inside the hot-melting crucible is gradually heated to a molten state.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0035] Example:

[0036] The following is combined Figures 1-7 This invention describes a high-purity aluminum vacuum purification device and its purification process.

[0037] like Figures 1-7As shown in the figure, an embodiment of the present invention provides a high-purity aluminum vacuum purification device, comprising: a support 1, a hot-melting mechanism 2, a segregation mechanism 3, a cooling mechanism 4, and a driving mechanism 5. The support 1 supports all components of the device, ensuring the stability and coaxiality of each mechanism after installation, and preventing vibration from affecting purification accuracy during operation. The hot-melting mechanism 2 is used to melt aluminum raw materials; its core function is to heat the solid aluminum raw materials to a molten state, providing qualified high-temperature aluminum liquid for the subsequent impurity segregation process, ensuring complete melting of the aluminum raw materials without excessive oxidation. The segregation mechanism 3 is fixedly connected to the hot-melting mechanism 2 and is used for impurity segregation of the high-temperature aluminum liquid. By controlling the temperature gradient and the flow state of the aluminum liquid, impurities in the aluminum liquid are separated due to differences in solubility, achieving preliminary purification of the aluminum liquid. The cooling mechanism 4 is installed between the support 1 and the segregation mechanism 3 for cooling the high-temperature aluminum liquid. It can quickly cool the high-temperature aluminum liquid after segregation treatment to the crystallization temperature, promoting the crystallization and precipitation of high-purity aluminum, while avoiding uneven crystallization and impurity inclusions caused by excessively rapid cooling. The drive mechanism 5 is fixedly connected to the support 1 and is used to drive the hot-melting mechanism 2, the segregation mechanism 3, and the cooling mechanism 4. It provides stable power for the movement of each mechanism, ensures coordinated operation of each process, realizes automated control, and reduces errors caused by manual intervention.

[0038] The hot-melting mechanism 2 includes a hot-melting crucible 21, a hot-melting outer shell 22, an electromagnetic heating coil 23, an electromagnetic stirrer 24, a heat insulation layer 25, and an anti-splash ring 26. The anti-splash ring 26 is fixedly connected to the hot-melting crucible 21 to prevent molten aluminum from splashing out of the crucible during melting and stirring due to violent movement, thus avoiding material waste and equipment damage, and also providing some heat insulation. The hot-melting crucible 21 is fixedly connected to the hot-melting outer shell 22. As a container for melting aluminum raw materials, it possesses high-temperature resistance and corrosion resistance, and can stably support high-temperature molten aluminum. Its fixed connection with the hot-melting outer shell 22 effectively disperses the stress on the crucible, extending its service life.

[0039] The heat insulation layer 25 is coaxially arranged and fixedly connected to the hot-melting crucible 21, wrapping around the outside of the crucible 21 to reduce heat loss from the crucible, reduce energy consumption, and protect the outer shell 22 and surrounding components from high-temperature damage. The electromagnetic heating coil 23 is installed outside the heat insulation layer 25, using electromagnetic induction heating to quickly and evenly provide heat to the hot-melting crucible 21, achieving rapid melting of the aluminum raw material with high heating efficiency and strong temperature controllability. The electromagnetic stirrer 24 is installed outside the electromagnetic heating coil 23 to stir the molten aluminum, ensuring a uniform temperature distribution and promoting the initial dispersion of impurities in the aluminum, preparing for subsequent segregation processes.

[0040] The segregation mechanism 3 includes a heat insulation plate 31, a segregation channel 32, a movable heating coil 33, a segregation disk 34, and a drive block 35. By precisely controlling the temperature and the flow of molten aluminum, effective separation of impurities from the molten aluminum is achieved. The heat insulation plate 31 is fixedly connected to the hot-melt outer shell 22, used to isolate heat transfer between the hot-melt mechanism 2 and the segregation mechanism 3, preventing the segregation effect of the segregation channel 32 from decreasing due to high temperatures, and also protecting other components of the segregation mechanism.

[0041] Segregation channel 32 is fixedly connected to and communicates with hot-melt crucible 21. Segregation plate 34 abuts against hot-melt crucible 21 and is slidably connected to segregation channel 32. It controls the opening and closing of hot-melt crucible 21. After the aluminum melt has melted and been stirred, the channel is opened by sliding segregation plate 34, allowing the aluminum melt to enter the segregation channel. Simultaneously, the channel can be closed after purification to prevent unpurified aluminum melt from mixing into the finished product. Movable heating coil 33 is installed outside segregation channel 32 and can move axially along segregation channel 32. It is used to control the temperature of different areas of the segregation channel, forming a reasonable temperature gradient, promoting the precipitation and separation of impurities in the aluminum melt, and improving the segregation effect. Drive block 35 is fixedly connected to movable heating coil 33 and screwed to drive mechanism 5. As the power transmission component of movable heating coil 33, it can move up and down under the drive of drive mechanism 5, thereby adjusting the position of movable heating coil 33 and achieving precise control of the temperature gradient.

[0042] The cooling mechanism 4 includes a cooling channel 41, a cooling pipe 42, and a transfer pipe 43. Through efficient heat exchange, it rapidly reduces the temperature of the segregated aluminum liquid, promoting high-purity aluminum crystallization and ensuring purification quality. The cooling channel 41 is fixedly connected to the segregation channel 32 and serves as the cooling and crystallization site for the high-temperature aluminum liquid. Its connection to the segregation channel 32 allows the segregated aluminum liquid to smoothly enter the cooling channel. The smooth inner wall of the channel reduces aluminum liquid residue and impurity adhesion.

[0043] Cooling pipe 42 is installed outside cooling channel 41 in a wraparound manner, completely enclosing the cooling channel 41. The flow of coolant within the pipe facilitates heat exchange with the molten aluminum within the cooling channel, rapidly removing heat and achieving rapid cooling. One end of transmission pipe 43 is fixedly connected to cooling pipe 42, while the other end is connected to an external refrigeration system. This system circulates and transfers the coolant, delivering the cooled liquid to the external refrigeration system for cooling, and then returning the cooled liquid to cooling pipe 42, ensuring the continuity and stability of the cooling effect.

[0044] The drive mechanism 5 includes lifting component 1 51 and lifting component 2 52. The two lifting components work together to provide power to the hot melting mechanism and the segregation mechanism, respectively, to ensure the orderly progress of the melting and segregation processes.

[0045] The lifting component 51 is used to drive the drive moving block 35 to move up and down. By precisely controlling the lifting distance of the drive moving block 35, the position of the moving heating coil 33 is adjusted, thereby achieving precise control of the temperature gradient of the segregation channel 32.

[0046] The lifting assembly 52 is used to drive the segregation disk 34 to move up and down. By controlling the lifting of the segregation disk 34, the hot melt crucible 21 is turned on and off, and the moving heating coil 33 and the segregation disk 34 can move synchronously, thereby accurately controlling the segregation temperature.

[0047] The lifting assembly 51 includes a lead screw 511, a clutch shaft 512, a lifting slide 513, a fixed terminal 514, two limit plates 515, a trigger rod 516, a self-locking assembly 517, and a motor 518. The drive block 35 is screwed to the lead screw 511. The rotational movement of the lead screw 511 converts the rotational power into the linear lifting motion of the drive block 35. This screw connection ensures precise positioning of the drive block 35, guaranteeing the positional accuracy of the moving heating coil 33. One end of the lead screw 511 is rotatably connected to the heat insulation layer 25, and the other end engages with the clutch shaft 512. The heat insulation layer 25 provides stable support for the lead screw 511, and the engagement with the clutch shaft 512 enables power transmission, allowing the power of the motor 518 to be transmitted to the lead screw 511 via the clutch shaft 512.

[0048] The clutch shaft 512 is slidably connected to the fixed terminal 514 and the lifting slide 513. The fixed terminal 514 guides and limits the clutch shaft 512, ensuring that the clutch shaft 512 moves in a fixed direction. The lifting slide 513 provides installation and movement space for the clutch shaft 512 and transmits the driving force of the motor 518. Both limit plates 515 are fixedly connected to the clutch shaft 512 to limit the range of motion of the trigger lever 516.

[0049] A trigger rod 516 is installed between two limit plates 515 and is rotatably connected to the clutch shaft 512. When the lifting assembly 52 controls the segregation disk 34 to move downward, it pushes the trigger rod 516 when it reaches the first set position, thereby disconnecting the clutch shaft 512 from the lead screw 511 and stopping the moving heating coil 33. When the lifting assembly 52 controls the segregation disk 34 to move upward, it contacts the trigger rod 516 when it reaches the second set position, causing it to control the clutch shaft 512 to move upward and then contact the lead screw 511. When the clutch shaft 512 rotates, the end of the clutch shaft 512 that contacts the lead screw 511 engages, thereby driving the lead screw 511 to rotate. The engagement between the lead screw 511 and the clutch shaft 512 is achieved by a tight interlocking of mutually cooperating concave and convex structures, thus achieving a mutually adaptive effect. A self-locking assembly 517 is installed inside the clutch shaft 512 to prevent the clutch shaft from falling back. Only when the lifting assembly 52 drives the segregation plate 34 to descend will the self-contained assembly 517 be squeezed against the lifting slide 513, thereby retracting into the clutch shaft 512. The lifting slide 513 is fixedly connected to the drive shaft of the motor 518. The motor 518 provides rotational power to the lifting slide 513, thereby driving the clutch shaft 512 to move, realizing the power output of the entire lifting assembly 51.

[0050] The internal channel of the lifting slide 513 has a square cross-section, and the cross-section of the end of the clutch shaft 512 that contacts the lifting slide 513 is adapted to the internal channel of the lifting slide 513. The square cross-section design can effectively prevent relative rotation between the clutch shaft 512 and the lifting slide 513, ensuring efficient power transmission, while improving the stability and accuracy of the movement of the clutch shaft 512, and avoiding the influence of rotational deviation on the positional accuracy of the drive block 35.

[0051] The lifting assembly 52 includes a lifting mechanism 521, a lifting rod 522, and a trigger platform 523. It enables smooth lifting and lowering of the segregation plate 34, ensuring the opening and closing of the hot-melt crucible 21. The lifting mechanism 521 is fixedly connected to the support 1. One end of the lifting rod 522 is fixedly connected to the drive shaft of the lifting mechanism 521, and the other end is fixedly connected to the segregation plate 34. The trigger platform 523 is coaxially arranged and fixedly connected to the lifting rod 522. The trigger rod 516 is slidably connected to the lifting rod 522 and abuts against the trigger platform 523. The trigger platform 523 supports the trigger rod 516. When the lifting rod 522 drives the segregation plate 34 to rise and fall, the trigger platform 523 moves synchronously, thereby squeezing the trigger rod 516 and realizing the up-and-down movement of the trigger rod 516.

[0052] The lifting rod 522 includes an upper rod 5221 and a lower rod 5222. One end of the upper rod 5221 is fixedly connected to the segregation plate 34, and the other end is fixedly connected to the lower rod 5222. The lower rod 5222 is fixedly connected to the drive shaft of the lifting mechanism 521. The cross-sectional diameter of the upper rod 5221 is larger than that of the lower rod 5222. The larger diameter of the upper rod 5221 allows it to push the trigger rod 516 downward when moving downward.

[0053] The self-locking assembly 517 includes two locking blocks 5171 and a spring 5172. The two locking blocks 5171 are rotatably connected to the clutch shaft 512, and the two ends of the spring 5172 are fixedly connected to the two locking blocks 5171 respectively. When pressed by the lifting slide 513, the two locking blocks 5171 will retract inward, thereby allowing the clutch shaft 512 to slide into the lifting slide 513, realizing the disengagement of the clutch shaft 512 from the lead screw 511. When the lifting rod 522 in the second lifting assembly 52 moves upward, the trigger platform 523 will drive the trigger rod 516 to move upward. After the self-locking assembly disengages from the lifting slide 513, it will open outward under the action of the spring 5172, preventing the clutch shaft 512 from sliding into the lifting slide 513 before the upper rod 5221 contacts the trigger rod 516.

[0054] This embodiment also provides a high-purity aluminum vacuum purification process, including:

[0055] First, after the device is started, the drive mechanism 5 begins to work. Its lifting components 51 and 52 work together to provide stable power for the entire purification process and ensure that all mechanisms operate in an orderly manner. In the initial state, the lifting component 52 drives the segregation disk 34 to the closed position, sealing the connection between the segregation channel 32 and the hot-melt crucible 21 to prevent molten aluminum from flowing into the segregation mechanism 3 in advance. At the same time, the lifting component 51 drives the moving heating coil 33 to the initial set position.

[0056] The hot-melting stage then begins, and the hot-melting mechanism 2 starts operating. The electromagnetic heating coil 23 uses electromagnetic induction heating to transfer heat to the hot-melting crucible 21. The heat insulation layer 25 wrapped around the outside of the hot-melting crucible 21 reduces heat loss, lowers energy consumption, and protects surrounding components. As the temperature rises, the solid aluminum material inside the hot-melting crucible 21 is gradually heated to a molten state. During this process, the electromagnetic stirrer 24 continuously stirs the molten aluminum, ensuring a uniform temperature distribution and promoting the initial dispersion of impurities, laying the foundation for subsequent segregation processes. The anti-splash ring 26, fixedly connected to the hot-melting crucible 21, effectively prevents molten aluminum from splashing out during melting and stirring, avoiding material waste and equipment damage.

[0057] Once the aluminum raw material has completely melted into qualified high-temperature molten aluminum, it enters the segregation purification stage. At this time, the lifting component 52 of the drive mechanism 5 starts working, driving the lifting rod 522 to move the segregation disk 34 downward, opening the connection between the segregation channel 32 and the hot-melt crucible 21, allowing the high-temperature molten aluminum to slowly flow into the segregation mechanism 3 through the segregation channel 32. During this process, the upper rod 5221 moves downward, pushing the trigger rod 516 to move, causing the self-locking component 517 to be squeezed by the lifting slide 513. The two locking blocks 5171 retract inward, and the clutch shaft 512 can slide within the lifting slide 513, disconnecting the clutch shaft 512 from the lead screw 511, and temporarily stopping the movement of the moving heating coil 33.

[0058] The rotation of the lead screw 511 converts power into the linear lifting motion of the drive block 35. The drive block 35 moves the moving heating coil 33 axially along the segregation channel 32, precisely controlling the temperature of different areas of the segregation channel 32 and forming a reasonable temperature gradient. The molten aluminum flows slowly within the segregation channel 32. Due to the difference in solubility between aluminum and impurities at different temperatures, impurities gradually precipitate from the molten aluminum, achieving preliminary purification of the molten aluminum. During this process, the heat insulation plate 31 isolates the heat transfer between the hot melting mechanism 2 and the segregation mechanism 3, preventing high temperatures from affecting the segregation effect and protecting the relevant components of the segregation mechanism. When the self-locking assembly 517 is pressed by the lifting slide 513, the two locking blocks 5171 retract inward, allowing the clutch shaft 512 to slide into the lifting slide 513, thus disengaging the clutch shaft 512 from the lead screw 511.

[0059] After segregation treatment, the purified aluminum liquid enters the cooling channel 41 of the cooling mechanism 4 through the segregation channel 32. Once the cooling mechanism 4 is activated, the transfer pipe 43 delivers the coolant cooled by the external refrigeration system to the cooling pipe 42. The cooling pipe 42 is installed in a wraparound manner, completely enclosing the cooling channel 41. Through the circulating flow of the coolant, efficient heat exchange occurs between the coolant and the high-temperature aluminum liquid within the cooling channel 41, rapidly cooling the aluminum liquid to its crystallization temperature and promoting the crystallization and precipitation of high-purity aluminum. Simultaneously, the smooth inner wall of the cooling channel 41 reduces aluminum residue and impurity adhesion, further ensuring purification quality. The cooled liquid, having absorbed heat, returns to the external refrigeration system through the transfer pipe 43 for further cooling, achieving coolant circulation and ensuring the continuity and stability of the cooling effect.

[0060] After purification, the second lifting assembly 52 drives the segregation disk 34 upward, the trigger platform 523 drives the trigger rod 516 upward, controls the clutch shaft 512 to move upward and contact the lead screw 511. When the clutch shaft 512 rotates, it engages with the lead screw 511. At this time, the motor 518 of the first lifting assembly 51 starts, driving the lifting slide 513 to rotate. Since the lifting slide 513 and the clutch shaft 512 are fitted with a square cross-section, the power is efficiently transmitted to the clutch shaft 512, which in turn drives the lead screw 511 to rotate and close the hot-melt crucible 21. At the same time, the self-locking assembly 517 locks, and the second round of purification begins. The entire process is automated through the control of the drive mechanism, reducing errors caused by manual intervention.

As the temperature rises, the solid aluminum material in the hot melt crucible (21) is gradually heated to a molten state. At the same time, the electromagnetic stirrer (24) continuously stirs the aluminum liquid, and the anti-splash ring (26) prevents the aluminum liquid from splashing out during the melting and stirring process. The driving lifting rod (522) drives the segregation plate (34) to move downward, opening the connection between the segregation channel (32) and the hot melting crucible (21), so that the high-temperature aluminum liquid flows into the segregation mechanism (3) through the segregation channel (32). The rotation of the lead screw (511) converts the power into the linear lifting motion of the drive block (35), which drives the moving heating coil (33) to move axially along the segregation channel (32) to control the temperature of different areas of the segregation channel (32). During this process, the heat insulation plate (31) isolates the heat transfer between the heat melting mechanism (2) and the segregation mechanism (3), preventing high temperature from affecting the segregation effect, and at the same time protecting the relevant components of the segregation mechanism; When the moving heating coil (33) moves to the bottom of the segregation channel (32), the self-locking assembly (517) is squeezed by the lifting slide (513), and the two locking blocks (5171) will retract inward, so that the clutch shaft (512) slides into the lifting slide (513) to realize the disengagement of the clutch shaft (512) from the lead screw (511); The purified aluminum liquid after segregation treatment enters the cooling channel (41) of the cooling mechanism (4) through the segregation channel (32) for crystallization; After purification is completed, the second lifting assembly (52) drives the segregation disk (34) to move upward, the trigger platform (523) drives the trigger rod (516) to move upward, controls the clutch shaft (512) to move upward and contact the lead screw (511). When the clutch shaft (512) rotates, it engages with the lead screw (511). At this time, the motor (518) of the first lifting assembly (51) starts, drives the lifting slide (513) to rotate, drives the lead screw (511) to rotate and close the hot melt crucible (21). At the same time, the self-locking assembly (517) locks and performs the second round of purification.
