Description

Technical Field

[0001] This utility model relates to the technical field of prebaked anode production equipment, specifically to a prebaked anode surface anti-oxidation composite coating equipment. Background Technology

[0002] In the electrolytic aluminum production process, prebaked anodes, as important conductive and reactive components, undergo oxidation reactions with air and carbon dioxide under high-temperature electrolysis conditions, leading to carbon slag shedding and increased anode carbon consumption. Currently, the main methods to reduce carbon consumption include adding antioxidant additives to the anode paste and spraying an antioxidant coating onto the anode surface.

[0003] In the existing technology, when applying an anti-oxidation composite coating to the surface of a prebaked anode, traditional coating equipment tends to repeatedly spray the sides of the prebaked anode when it is flipped over for re-spraying, resulting in inconsistent coating thickness on the surface of the prebaked anode.

[0004] Therefore, this utility model proposes a prebaked anode surface anti-oxidation composite coating equipment to solve the above problems. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a prebaked anode surface anti-oxidation composite coating equipment, the prebaked anode surface anti-oxidation composite coating equipment includes: a coating shell 1, a workbench 2 installed on the surface of the coating shell 1, a lifting mechanism 3 installed inside the coating shell 1, a first set of spray heads 4 and a second set of spray heads 5 installed at the bottom of the lifting mechanism 3, a movable groove 6 opened in the center of the coating shell 1, the movable groove 6 passing through the center of the workbench 2, and a moving component 7 installed inside the movable groove 6;

[0022] In use, a non-stick diaphragm layer is applied to the surfaces of the workbench 2 and the moving component 7 to prevent the anti-oxidation composite coating from sticking to their surfaces. The prebaked anode is placed on the workbench 2, and the moving component 7 pushes the prebaked anode to move it on the workbench 2, making it easy to move the prebaked anode under the first set of spray heads 4. After the first set of spray heads 4 evenly sprays the anti-oxidation composite coating onto the upper surface and the front and rear sides of the prebaked anode, the prebaked anode is moved to the lower surface and the left and right sides of the prebaked anode to evenly spray the anti-oxidation composite coating. This allows for rapid and uniform spraying of the anti-oxidation composite coating onto multiple surfaces of the prebaked anode.

[0023] Example 2: Based on Example 1, a structure is provided to drive the prebaked anode to move in parallel. The moving component 7 includes a set of parallel rotating rods 8. Bearings 9 are installed at both ends of the rotating rods 8. The bearings 9 are fixed to the side wall of the movable groove 6. Gears 10 are installed on the outer surface of the rotating rods 8. A drive motor 11 is installed at one end of the rotating rods 8. The wrap angle between the gears 10 and the toothed chain plate 12 is 20°. The toothed chain plate 12 is sleeved on the outer surface of the gears 10. Several push plates 13 are installed on the outer surface of the toothed chain plate 12. The several push plates 13 are evenly distributed in an array.

[0024] In use, the drive motor 11 drives the rotating rod 8 to rotate under the control of the electric drive system. The rotating rod 8 supports the gear 10 under the action of the bearing 9, and drives the toothed chain plate 12 through tooth meshing. This causes the push plate 13 on the surface of the toothed chain plate 12 to push the prebaked anode to move in the center of the worktable 2.

[0025] Example 3: Based on Example 2, a structure for flipping the prebaked anode is provided. A limiting plate 14 is installed on the surface of the coating shell 1. A cylinder 15 is fixedly installed at the bottom of the limiting plate 14. The cylinder 15 is located inside the coating shell 1. A lifting rod 16 is installed at the output end of the cylinder 15. A drive shaft 17 is installed at the top of the lifting rod 16. A rotating block 18 is installed on the outer surface of the drive shaft 17. A power motor 19 is installed inside the rotating block 18. A mechanical gripper 20 is installed at the output end of the power motor 19.

[0026] In use, under the control of the power control system, the cylinder 15 drives the lifting rod 16 to move the rotating block 18 up and down, which in turn drives the mechanical gripper 20 to move up and down. This allows the mechanical gripper 20 to grip the two uncoated sides of the prebaked anode and lift them up under the drive and control of the power control system. Under the power drive of the motor 19, the mechanical gripper 20 is rotated so that the prebaked anode is rotated 180°. Then, the cylinder 15 drives the lifting rod 16 down and the mechanical gripper 20 down to place the prebaked anode on the worktable 2. Under the control of the power control system, the drive shaft 17 rotates the mechanical gripper 20 away from the top of the worktable 2, so that the second set of spray heads 5 can completely coat the prebaked anode.

[0027] In actual use, a non-stick diaphragm layer is applied to the surfaces of the workbench 2 and the moving component 7 to prevent the anti-oxidation composite coating from adhering to their surfaces. The prebaked anode is placed on the workbench 2, and the rotating rod 8 is driven to rotate by the drive motor 11 under the control of the electric drive system. The rotating rod 8, under the action of the bearing 9, supports the gear 10 and drives the toothed chain plate 12 through tooth meshing. This causes the push plate 13 on the surface of the toothed chain plate 12 to push the prebaked anode to move in the center of the workbench 2. After the first set of spray heads 4 evenly sprays the anti-oxidation composite coating onto the upper surface and the front and rear sides of the prebaked anode, the moving component 7 moves the prebaked anode that has not been fully sprayed to below the second set of spray heads 5. The cylinder 15 is controlled by the electric control system. Under the control of the power control system, the lifting rod 16 drives the rotating block 18 to move up and down, which in turn drives the mechanical gripper 20 to move up and down. This allows the mechanical gripper 20 to grip the prebaked anode tightly and rise under the drive and control of the power control system. Under the power drive of the power motor 19, the mechanical gripper 20 is rotated, causing the prebaked anode to rotate 180° and flip over. Then, the cylinder 15 drives the lifting rod 16 downward and the mechanical gripper 20 to descend and place the prebaked anode on the worktable 2. Under the control of the power control system, the drive shaft 17 rotates the mechanical gripper 20 away from the top of the worktable 2, making it easier for the second set of spray heads 5 to spray the prebaked anode completely. The first set of spray heads 4 and the second set of spray heads 5 are located at the bottom of the lifting mechanism 3 and can spray multiple prebaked anodes at the same time.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
