Description

Technical Field

[0001] This invention relates to the field of high-purity aluminum purification technology, specifically to a purification furnace and method for producing high-purity aluminum. Background Technology

[0002] A purification furnace is an industrial device used for the purification of substances. It removes impurities from raw materials through physical or chemical methods to obtain a target product of high purity. Its specific definition and application depend on the materials being processed and the process.

[0003] A search revealed a Chinese patent with application number "CN202020841045.2", which specifically describes a purification furnace for producing high-purity aluminum. The furnace includes a main body and a container fixedly installed inside the main body. The main body is also equipped with a stirring device that extends into the container. The stirring device includes a driving mechanism, a graphite rod, and a graphite head fixedly installed at the bottom of the graphite rod. The graphite head moves in a rectangular trajectory under the action of the driving mechanism.

[0004] In existing refining furnaces, the aluminum liquid is stirred by a stirring component to facilitate the removal of air from the aluminum liquid. However, impurities on the surface of the aluminum liquid will float on the surface. If not cleaned in time, the purity of the aluminum liquid will be reduced. Because the slag adsorbs a large amount of hydrogen and oxides, it will increase the porosity inside the ingot. When rolling high-strength aluminum alloys, it is very easy to crack and break the billet, which will affect the quality of aluminum products.

[0005] Therefore, the present invention proposes a purification furnace and method for producing high-purity aluminum to solve the problems mentioned above. Summary of the Invention

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides the following technical solutions:

[0036] Example 1

[0037] Please see Figure 1 - Figure 9A refining furnace for producing high-purity aluminum includes a furnace body 1. A feed pipe 2 is fixedly connected to the left side of the furnace body 1, and a discharge pipe 4 is fixedly connected to the right side of the furnace body 1. A motor 5 is fixedly connected to the upper side of the furnace body 1. A stirring unit 6 is arranged inside the furnace body 1, and a transparent window 3 is arranged at the front of the furnace body 1. The stirring unit 6 includes a rotating rod 61, which is rotatably connected to the inner side of the furnace body 1. A lifting cylinder 62 is arranged inside the rotating rod 61, and an installation cylinder 63 is fixedly connected to the upper side of the lifting cylinder 62. A curved groove 64 is formed on the outer side of the installation cylinder 63. A fixing plate 66 is fixedly connected to the inner side of the furnace body 1, and a contact rod 65 is fixedly connected to the rear side of the fixing plate 66. The contact rod 65 is located inside the curved groove 64. Two sets of side blocks 68 are fixedly connected to the outer side of the lifting cylinder 62, and control rods 611 are rotatably connected to the outer sides of both sets of side blocks 68. A cleaning device is fixedly connected to the middle of the control rods 611. The inner side of the cleaning frame 69 is equipped with a filter screen 610. During purification, the molten aluminum is first introduced into the inner side of the furnace body 1 through the feed pipe 2, which facilitates the purification operation of the molten aluminum in the furnace body 1. During purification, the motor 5 is started, which drives the rotating rod 61 to rotate. The rotating rod 61 drives the lifting cylinder 62 to rotate, and the lifting cylinder 62 drives the extension plate 650 and the cleaning frame 69 to rotate, which facilitates the stirring of the molten aluminum. During the stirring process, the lifting cylinder 62 drives the mounting cylinder 63 to rotate. Under the action of the curved groove 64 and the contact rod 65, the mounting cylinder 63 and the lifting cylinder 62 are controlled to move up and down repeatedly, which facilitates the control of the extension plate 650 and the cleaning frame 69 to move up and down repeatedly, enhances the stirring effect, and facilitates the filter screen 610 to filter the impurities on the upper layer of the molten aluminum when the cleaning frame 69 rises, which facilitates the subsequent cleaning and collection. All components of the stirring unit 6 are made of high temperature resistant materials.

[0038] Both control levers 611 have a rotating block 612 fixedly connected to their front ends. An inclined plate 613 is rotatably connected to the outer side of the rotating block 612. A rotating shaft 631 is rotatably connected to the front side of the lifting cylinder 62. A control plate 614 is fixedly connected to the front end of the rotating shaft 631. The inclined plate 613 is rotatably connected to the rotating block 612. A fixing cover 67 is fixedly connected to the outer side of the lifting cylinder 62. A through hole 615 and a through hole 641 are provided on the outer side of the mounting cylinder 63. The through hole 615... A slider 616 is slidably connected to the inner side of the shaft 631. The slider 616 is fixedly connected to the rotating rod 61. A base plate 617 is fixedly connected to the lower side of the slider 616. A toothed plate 618 is fixedly connected to the outer side of the base plate 617. A gear 619, meshing with the toothed plate 618, is fixedly connected to the outer side of the rotating shaft 631. The toothed plate 618 is located to the left of the gear 619. Two inclined plates 613 are arranged in parallel. The base plate 617 is slidably connected to the fixed cover 67. (The last sentence appears to be incomplete and possibly refers to a specific location or feature in the lifting cylinder.) When the lifting cylinder 62 rises, it drives the gear 619 to rise (at this time, the cleaning frame 69 is arranged parallel to the lifting cylinder 62). At this time, the gear 619 meshes with the toothed plate 618. As the lifting cylinder 62 rises, the gear 619 rotates counterclockwise. The gear 619 drives the rotating shaft 631 to rotate, the rotating shaft 631 drives the control plate 614 to rotate, the control plate 614 drives the inclined plates 613 on both sides to rotate, and the inclined plates 613 drive the rotating blocks 612 to rotate. Since the inclined plates 613 on both sides are arranged parallel, the rotating blocks 612 on both sides rotate in opposite directions. The rotating blocks 612 drive the control rod 611 to rotate, and the control rod 611 drives the cleaning frame 69 to rotate. The cleaning frames 69 on both sides move together and rotate. When the cleaning frame 69 separates from the aluminum liquid, the cleaning frame 69 is tilted, so that the filter screen 610 on the cleaning frame 69 filters the upper impurities (at this time, the impurities are located on the surface of the filter screen 610), which facilitates the cleaning of the impurities in the later stages.

[0039] A collection box 622 is fixedly connected to the lower side of the side block 68. A sealing plate 623 is provided on the inner side of the collection box 622, and the sealing plate 623 is slidably connected to the collection box 622. Guide plates 634 are fixedly connected to the upper side of both cleaning frames 69. Guide blocks 635 are slidably connected to the outer side of the guide plates 634. A top plate 636 is fixedly connected to the upper side of the guide blocks 635. A scraper 637 is fixedly connected to the lower side of the top plate 636. An installation device is fixedly connected to the upper side of the top plate 636. Mounting block 638 is rotatably connected to the outer side of mounting block 638 via an inclined cylinder 639. Sliding slider 642 is slidably connected to the inner side of perforation 641. Sliding slider 642 is fixedly connected to the rotating rod 61. Mounting block 643 is fixedly connected to the outer side of sliding slider 642. A connecting plate 640 is rotatably connected to the outer side of mounting block 643. The connecting plate 640 is slidably connected to the inclined cylinder 639. When the cleaning frame 69 rotates towards the lifting cylinder 62, ... Under the action of the inclined cylinder 639 and the connecting plate 640, the scraper 637 moves along the trajectory of the guide plate 634, so that the scraper 637 cleans the impurities on the surface of the filter screen 610 and collects the upper impurities through the collection box 622 at the bottom. When the cleaning frame 69 is arranged in parallel with the lifting cylinder 62, the connecting plate 640 slides inside the inclined cylinder 639 when the cleaning frame 69 is brought together, which facilitates the movement of the scraper 637. Part of the connecting plate 640 is located inside the inclined cylinder 639, and the connecting plate 640 can slide inside the inclined cylinder 639 to facilitate the movement of the scraper 637. When the cleaning frame 69 is arranged in parallel with the lifting cylinder 62, the scraper 637 is located at the end of the cleaning frame 69 near the side block 68. When the cleaning frame 69 is arranged perpendicular to the lifting cylinder 62, the scraper 637 is located at the end of the side block 68. When the cleaning frame 69 moves closer to the mounting cylinder 63 and rotates, the scraper 637 scrapes the impurities and moves them.

[0040] An L-shaped plate 624 is fixedly connected to the outer side of the sealing plate 623. A movable plate 627 is fixedly connected to the outer side of the L-shaped plate 624. A protective cover 620 is fixedly connected to the outer side of the lifting cylinder 62. A linkage plate 628 is rotatably connected to the outer side of both movable plates 627. A connecting block 629 is rotatably connected to the outer side of the linkage plate 628. A lifting block 630 is fixedly connected to the outer side of the connecting block 629. A telescopic rod 632 and a spring 633 are fixedly connected between the outer side of the lifting block 630 and the inner wall of the protective cover 620. A top hole 621 is opened on the upper side of the protective cover 620. A toothed plate 618 is located above the lifting block 630. The movable plate 627 is slidably connected to the protective cover 620. The outer side of the fixed cover 67 begins to have a permeable opening. The outer side of the L-shaped plate 624 is fixedly connected to the rear plate 625. As the lifting cylinder 62 rises, the toothed plate 618 abuts against the lifting block 630 and descends (at this time, the cleaning frame 69 is perpendicular to the lifting cylinder 62, filtering the device, and the collection box 622 leaves the aluminum liquid). The lifting block 630 drives the linkage plate 628 to rotate, the linkage plate 628 drives the moving plate 627 to move, the moving plate 627 drives the L-shaped plate 624 to move, and the L-shaped plate 624 drives the sealing plate 623 to move. The sealing plates 623 on both sides move away from each other, so that the top opening of the collection box 622 is opened to facilitate the collection of impurities. When the lifting cylinder 62 descends, the sealing plate 623 seals the collection box 622 to prevent aluminum liquid from entering the collection box 622.

[0041] Example 2

[0042] Based on Example 1, such as Figure 10 , Figure 11 As shown, a discharge hole 644 is provided on the outer side of the collection box 622. A collection plate 626 is provided on the outer side of the collection box 622, and a support plate 645 is provided on the inner side of the collection box 622. A lifting rod 646 is fixedly connected to the lower side of the support plate 645. A spring 647 is fixedly connected between the outer side of the support plate 645 and the inner wall of the collection box 622. The lower end of the lifting rod 646 passes through the lower side of the collection box 622. Two side cylinders 649 are fixedly connected to the outer side of the lifting cylinder 62, and an extension plate 650 is provided on the inner side of the side cylinders 649. A stabilizing block 651 is fixedly connected to the upper side of the extension plate 650. An inclined plate 648 is rotatably connected to the outer side of the stabilizing block 651. The inclined plate 648 is rotatably connected to the lifting rod 646. As impurities are collected, they fall onto the bearing plate 645. Under the action of gravity, the bearing plate 645 descends. The bearing plate 645 drives the lifting rod 646 to descend. The lifting rod 646 drives the inclined plate 648 to rotate. The inclined plate 648 drives the extension plate 650 to extend, thereby increasing the stirring range of the extension plates 650 on both sides and preventing impurities from clumping together.

[0043] A purification method for producing high-purity aluminum includes the following steps:

[0044] S1. The aluminum liquid is added to the inside of the furnace body 1 through the feed pipe 2 for purification. During the purification process, the motor 5 is started to control the lifting cylinder 62 and the extension plate 650 to rotate and stir the aluminum liquid.

[0045] S2. During the stirring process, the cleaning frames 69 on both sides are controlled to move up and down repeatedly. When the cleaning frames 69 on both sides rise, they converge towards the middle, and the scraper 637 is controlled to move horizontally. The scraper 637 cleans up the impurities filtered down from the upper layer and collects the impurities through the collection box 622.

[0046] S3. During the impurity cleaning process, the lifting rod 646 descends, and the lifting rod 646 drives the extension plate 650 to move, increasing the stirring range. Finally, the aluminum liquid is discharged through the discharge pipe 4.
