Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum waste resource recovery, and specifically relates to a process for recovering aluminum ash slag renewable resources. Background Art

[0002] Aluminum slag is a solid waste generated during the aluminum industry's smelting, casting, and recycling processes. It primarily consists of alumina, metallic aluminum, salts, and other impurities. Depending on its source, aluminum slag can be divided into primary and secondary aluminum slag. Because aluminum slag contains a certain amount of recyclable metallic aluminum and may release hazardous substances, it is both a hazardous waste and an important secondary resource. Scientific recycling and resource utilization technologies can effectively reduce environmental pollution and increase the recycling rate of aluminum resources.

[0003] In the prior art, when recycling aluminum ash slag, it is necessary to perform a pretreatment operation on the aluminum ash slag. Since the volume of aluminum ash slag varies, the prior operation does not completely crush the aluminum ash slag during the pretreatment operation, resulting in large lumps in the aluminum ash slag, which leads to incomplete subsequent recycling and treatment process, resulting in a high residual aluminum content, which is not conducive to the subsequent recycling and treatment work and reduces practicality.

[0004] Moreover, during the pre-processing stage of aluminum particles, such as crushing and screening, they are easily oxidized due to exposure to air or heat generated by mechanical friction, resulting in a lower recovery rate of metal aluminum. At the same time, there is a large amount of dust and toxic gases that affect the work of operators and reduce practicality.

[0005] Therefore, we propose a recycling process for aluminum ash slag renewable resources to solve the problems encountered above. Summary of the Invention

[0006] The purpose of the present invention is to solve the problems mentioned in the above background technology and to propose a recycling process for aluminum ash slag renewable resources.

[0031] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1:

[0033] See also Figure 1 - Figure 4 As shown, a recycling process for aluminum ash slag renewable resources, wherein a first screening slot 2 is provided on the upper surface of an annular sieve plate 1, a circular sieve plate 3 is fixedly connected to the interior of the annular sieve plate 1, a second screening slot 4 is provided on the upper surface of the circular sieve plate 3, a guide cylinder 5 is provided below the first screening slot 2, a sealing cylinder 6 is fixedly connected to the outer surface of the annular sieve plate 1, a support frame 7 is fixedly connected to the edge of the upper surface of the sealing cylinder 6, a first drive motor 8 is provided in the middle position of the upper surface of the support frame 7, a power output end drive rod 9 of the first drive motor 8, a stirring frame 10 is fixedly connected to the middle position of the outer surface of the driving rod 9, and a stirring frame 2 11 is fixedly connected to the bottom position of the outer surface of the driving rod 9;

[0034] The lower surface of the driving rod 1 (9) is fixedly connected to a connecting rod 12, which is fixedly connected to a conical crushing roller 1 (13) on its lower surface. A crushing cylinder 1 (14) is disposed on the outer side of the conical crushing roller 1 (13). A blocking sleeve 15 is disposed above the conical crushing roller 1 (13). A sealing cylinder 1 (2) is disposed below the guide cylinder 5. A second driving motor 17 is mounted on the outer surface of the sealing cylinder 16 via a limiting bracket 44. A driving rod 18 is disposed at the power output end of the second driving motor 17. A driving gear 19 is fixedly connected to the lower surface of the driving rod 18. The outer surface of the driving gear 19 is meshed with a driving assembly 20. When the second driving motor 17 is activated, the driving rod 18 drives the driving gear 19 to rotate. The driving gear 19 meshes with a gear ring 21 in the driving assembly 20, and according to the principle of gear transmission, the driving gear ring 21 rotates. Six transmission gears 22 on the inner side of the gear ring 21 mesh with the gear ring 21. Driven by the gear ring 21, the transmission gears 22 not only rotate about their own axes but also revolve around the gear ring 21. The transmission gears 22 drive the first gear 24 to rotate via the fixed rod 23. The first gear 24 then meshes with the four second gears 26, causing the second gears 26 to rotate, thereby transmitting power to each gear assembly in sequence.

[0035] In the prior art, when recycling aluminum ash slag, it is necessary to perform a pretreatment operation on the aluminum ash slag. Since the aluminum ash slag has different sizes, the existing operation does not completely crush the aluminum ash slag during the pretreatment operation, resulting in large lumps in the aluminum ash slag, which leads to incomplete subsequent recycling and treatment processes, resulting in a high residual aluminum content, which is not conducive to the subsequent recycling and treatment work and reduces practicality.

[0036] Aluminum ash slag is poured through the feed port 45 on the sealing plate 33 onto the annular sieve plate 1 and the circular sieve plate 3, distributing the slag across the sieve plates in preparation for screening. The first drive motor 8 is activated, driving the drive rod 9 to rotate, driving the stirring frame 10 and the stirring frame 2 11 to rotate. The stirring frame agitates the aluminum ash slag on the annular sieve plate 1 and the circular sieve plate 3, causing smaller particles to fall through the first screening trough 2 and the second screening trough 4. Aluminum ash particles passing through the first screening trough 2 enter the sealing cylinder 2 16 via the guide cylinder 5. Larger particles pass through the second screening trough 4 and enter the crushing cylinder 14 for crushing. As the drive rod 9 rotates, the connecting rod 12 on its lower surface drives the conical crushing roller 13 to rotate. The conical crushing roller 13 squeezes and crushes the larger aluminum ash particles remaining on the sieve plates within the crushing cylinder 14. The blocking sleeve 15 is located above the conical crushing roller 13 to prevent aluminum ash slag from splashing upward during the crushing process. The second drive motor 17 is started, the drive rod 18 rotates, and the drive gear 19 on the lower surface of the drive rod 18 starts to rotate, providing power to the drive assembly 20 to prepare for crushing smaller particles.

[0037] Example 2:

[0038] Please refer to Figure 5 - Figure 7 As shown, the drive assembly 20 includes a gear ring 21, the inner side of which is meshed with six transmission gears 22. The upper surfaces of the six transmission gears 22 are fixedly connected to a fixing rod 23, the upper surface of which is fixedly connected to a first gear 24, the upper surface of which is fixedly connected to a connecting column 1 25. The outer surface of the first gear 24 is meshed with four second gears 26, the upper surfaces of which are fixedly connected to connecting columns 27. The connecting columns 1 25 are fixedly connected to the upper surface of the first gear 24, and the connecting columns 27 are fixedly connected to the upper surface of the second gear 26. When the first gear 24 and the second gear 26 rotate, they drive the connecting columns 1 25 and 27 to rotate respectively.

[0039] A conical crushing roller 28 is fixedly connected to the upper surface of the connecting column 1 25, and an auxiliary crushing roller 29 is fixedly connected to the upper surface of the connecting column 27. A crushing cylinder 2 30 is provided on the outer side of the auxiliary crushing roller 29. The conical crushing roller 28 is fixed to the upper surface of the connecting column 1 25, and its conical structure has a special crushing effect during the rotation. As the connecting column 1 25 rotates, the conical crushing roller 28 rotates at high speed inside the crushing cylinder 2 30. Due to its conical characteristics, the gap in contact with the aluminum ash slag gradually changes during rotation, squeezing and crushing the aluminum ash slag entering the crushing cylinder 2 30. The aluminum ash slag is subjected to pressure between the conical crushing roller 2 28 and the inner wall of the crushing cylinder 2 30, and the particles are gradually broken into smaller particle sizes.

[0040] Auxiliary crushing roller 29 is fixed to the upper surface of connecting column 27 and rotates within crushing drum 2 30 driven by connecting column 27. The auxiliary crushing roller 29 cooperates with conical crushing roller 28 to crush the aluminum ash slag from different angles and positions. The auxiliary crushing roller 29 can re-crush aluminum ash slag particles that were not fully crushed by conical crushing roller 28, or further refine the aluminum ash slag that has already been initially crushed. Its presence increases the crushing area and effect, improving the efficiency and quality of the aluminum ash crushing, allowing the aluminum ash slag to be more fully crushed to a particle size that meets the requirements of subsequent processing.

[0041] A drainage sleeve 31 is provided inside the second crushing barrel 30. An arc-shaped blocking plate 32 is fixedly connected to the outer surface of the drainage sleeve 31. The arc-shaped blocking plate 32 is located directly above the meshing connection between the drive gear 19 and the gear ring 21. The second crushing barrel 30 serves as the working place of the second conical crushing roller 28 and the auxiliary crushing roller 29, and constrains their movement to ensure that the crushing rollers process the aluminum ash slag in a fixed space. At the same time, a crushing working area is formed between the inner wall of the second crushing barrel 30 and the crushing rollers. The aluminum ash slag is crushed by the action of the crushing rollers in this area. In addition, a drainage sleeve 31 is provided inside the second crushing barrel 30, which can guide the aluminum ash slag to flow reasonably in the crushing barrel, so that the aluminum ash slag is evenly crushed, and at the same time prevent the aluminum ash slag from falling into the meshing connection between the drive gear 19 and the gear ring 21 and affecting its working state.

[0042] A sealing plate 33 is fixedly connected to the upper surface of the sealing cylinder 6, a cold air delivery pipe 34 is fixedly connected to the outer surface of the sealing plate 33, four feeding ports 45 are provided on the upper surface of the sealing plate 33, a load-bearing plate 35 is fixedly connected to the outer surface of the sealing cylinder 6, a cold air conveyor 36 is provided on the upper surface of the load-bearing plate 35, a connecting pipe 37 is provided at the output end of the cold air conveyor 36, and the connecting pipe 37 is fixedly connected to the cold air delivery pipe 34, wherein the cold air conveyor 36 is a device for generating cold air to reduce the temperature during the processing process, prevent the aluminum ash slag from undergoing adverse chemical reactions or generating harmful gases at high temperatures, and also protect the equipment from being affected by high temperatures.

[0043] A conical conveying tube 1 (38) is fixedly connected to the lower surface of crushing drum 1 (14), and a conical conveying tube 2 (39) is fixedly connected to the lower surface of crushing drum 2 (30). Conical conveying tube 1 (38) is connected to the lower surface of crushing drum 1 (14), while conical conveying tube 2 (39) is connected to the lower surface of crushing drum 2 (30). After the aluminum ash slag is crushed in crushing drums 1 (14) and 2 (30), it naturally flows downward due to gravity. The unique shape of the conical conveying tubes (wide at the top and narrow at the bottom) guides the material downward in a concentrated and orderly manner, preventing accumulation at the outlet and ensuring smooth material transportation.

[0044] The lower surface of the sealing cylinder 16 is fixedly connected to a circular plate 41 through a support column 40. The lower surface of the support column 40 is fixedly connected to a support platform 42. The interior of the support platform 42 is movably connected to a collection box 43.

[0045] In the existing technology, during the pre-processing stage of aluminum particles, such as crushing and screening, they are easily oxidized due to exposure to air or heat generated by mechanical friction, resulting in a reduced recovery rate of metal aluminum. At the same time, there is a large amount of dust and toxic gases that affect the work of operators, reducing practicality.

[0046] Check the sealing of sealing cylinder 1 6 and sealing cylinder 2 16 to ensure that the cold air conveyor 36, first drive motor 8, second drive motor 17 and other equipment are operating normally. Connect the cold air conveyor 36 to the cold air conveying pipe 34 through the connecting pipe 37. Turn on the cold air conveyor 36 to allow cold air to enter the sealing cylinder 1 6 through the cold air conveying pipe 34 to reduce the internal temperature of the equipment and prevent high temperatures generated during the aluminum ash slag treatment process from affecting equipment performance and treatment results. Start the second drive motor 17, and drive rod 2 18 drives the drive gear 19 to rotate. The drive gear 19 engages with the gear ring 21, driving the gear ring 21 to rotate. Driven by the gear ring 21, the six transmission gears 22 inside the gear ring 21 revolve around the gear ring 21 and rotate on their own. The transmission gear 22 drives the first gear 24 to rotate through the fixed rod 23. The first gear 24 engages with the four second gears 26, causing the second gears 26 to rotate. Connecting column 1 25 rotates with first gear 24, driving conical crushing roller 28 to crush aluminum ash slag within crushing drum 2 30. Connecting column 27 rotates with second gear 26, driving auxiliary crushing roller 29 to assist in crushing aluminum ash slag within crushing drum 2 30. During the crushing process, a drainage sleeve 31 guides the flow of aluminum ash slag within crushing drum 2 30, ensuring uniform crushing. An arc-shaped baffle 32, located directly above the meshing point between drive gear 19 and gear ring 21, prevents aluminum ash slag from splashing onto the gear meshing area and impacting transmission. After the secondary crushing, the aluminum ash slag falls through conical transport tube 2 39 on the lower surface of crushing drum 2 30 and ultimately lands in collection box 43 within support platform 42. Once collected, the aluminum ash slag in collection box 43 can be processed for subsequent resource recycling.

[0047] The guide tube 5, the sealing tube 1 6, the sealing tube 2 16, the conical transport tube 1 38, the conical transport tube 2 39 and the sealing plate 33 are all provided with insulation plates inside, which can effectively reduce the loss of cold air inside.

Obviously, many modifications and variations are possible based on the contents of this specification.
