However, aluminum powder raw materials often contain magnetic impurities (such as scrap steel) and non-magnetic impurities (such as large foreign objects or dust). These impurities reduce the purity and performance of aluminum powder. Therefore, developing efficient impurity removal equipment is of great significance for improving the quality of aluminum powder. This combined process technology represents the development trend in the field of aluminum powder raw material processing.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 and Figure 3 This utility model provides a technical solution for a magnetic separation-screening linkage impurity removal device for aluminum powder raw materials: it includes a screening box 1, with multiple fixing blocks 27 fixedly connected to the inner side wall of the screening box 1. Each fixing block 27 has three sets of connecting plates 13 fixedly connected to its outer surface. Each connecting plate 13 has three sets of sliding grooves 14 on its outer surface. Each sliding groove 14 has a slider 15 connected to its outer surface. The slider 15 connects to the grading screen 18. This structure gives the grading screen 18 good support stability and facilitates quick replacement and cleaning. The grading screen 18 is installed inside each set of sliding grooves 14. Each set of grading screens 18 has connecting grooves 16 on its side and the other side. The inner wall of each connecting groove 16 is connected to the outer surface of the slider 15. Each fixing block 27 has a limit block 7 connected to its upper surface. Each limit block 7 has a disassembly fixing column 17 connected to its bottom surface. Each disassembly fixing column 17 passes through the fixing block 27 and connects to the upper surface of each set of connecting plates 13.

[0022] like Figure 1 and Figure 4 As shown, multiple supports 2 are installed on the bottom surface of the screening box 1. Each support 2 has a protective pad 3 installed on its bottom surface. By setting the protective pad 3 on the bottom surface of each support 2, the vibration and noise during equipment operation are effectively reduced. A collection plate 19 is connected to the bottom surface of the screening box 1. The bottom surface of the collection plate 19 is connected to the discharge pipe 20. Through the collection plate 19 and the discharge pipe 20, the material after screening is collected and transported in a centralized manner, avoiding material residue and waste, and optimizing the production process.

[0023] like Figure 1 As shown, a door 4 is installed on the outer surface of the screening box 1, and a first handle 5 is fixedly installed on the outer surface of the door 4, which facilitates quick opening and closing by the operator, facilitates internal maintenance and cleaning, and introduces the magnetically separated material into the screening system to form a closed processing environment, reduce dust leakage, and improve the safety of equipment operation.

[0024] like Figure 1 and Figure 4 As shown, a top cover 6 is installed on the upper surface of the screening box 1. A collection pipe 21 is connected to the upper surface of the top cover 6. A magnetic cylinder 11 is connected to the upper surface of the collection pipe 21. A feed pipe 10 is connected to the outer surface of the magnetic cylinder 11. A cylinder cover 28 is installed at one end of the magnetic cylinder 11. A second handle 29 is fixedly connected to the outer surface of the cylinder cover 28 to facilitate internal inspection and cleaning of the magnetic cylinder 11. The linkage of the hinge 12 further improves the ease of operation. A second handle 29 is fixedly connected to the outer surface of the cylinder cover 28.

[0025] like Figure 1 and Figure 2 As shown, a hinge 12 is fixedly connected to the outer surface of the magnetic cylinder 11. A cylinder cover 28 is installed at the end of the hinge 12 away from the magnetic cylinder 11. A speed reducer 9 is installed at the end of the cylinder cover 28 away from the cylinder cover 28. A motor 8 is installed on the outer surface of the speed reducer 9.

[0026] like Figure 2 and Figure 4 As shown, the output end of the motor 8 passes through the outer surfaces of the reducer 9 and the magnetic cylinder 11 in sequence. The output end of the motor 8 is connected to the rotating shaft 22, and the outer surface of the rotating shaft 22 is connected to the magnetic plate 25.

[0027] like Figure 5 As shown, insulating material 23 is provided on both sides of the magnetic plate 25. The insulating material 23 effectively prevents the magnetic plate 25 from being interfered with by electricity and reduces the adsorption force. A scraper 24 is connected to the upper surface of the magnetic plate 25 and the insulating material 23. Multiple fixing rings 26 are connected to the outer surface of the rotating shaft 22. The inner wall of each fixing ring 26 is connected to the insulating material 23. The connection between each fixing ring 26 and the insulating material 23 further enhances the fixing stability of the magnetic plate 25 and the rotating shaft 22, ensuring the long-term stable operation of the equipment.

[0028] The working principle of this utility model is as follows: Aluminum powder raw material enters the magnetic cylinder 11 through the feed pipe 10. Inside the magnetic cylinder 11, the motor 8 drives the rotating shaft 22 to rotate through the reducer 9, which in turn drives the magnetic plate 25 to rotate at a low speed. During the rotation, the magnetic plate 25 generates a strong magnetic field, which adsorbs and separates magnetic impurities (such as scrap iron filings, iron powder, etc.) in the aluminum powder raw material. Insulating material 23 is provided on both sides of the magnetic plate 25 to prevent the magnetic plate 25 from directly contacting other metal parts, thus preventing short circuits or equipment damage. A scraper 24 is provided on the magnetic plate 25. As the magnetic plate 25 rotates, the scraper 24 continuously scrapes off the magnetic impurities adsorbed on the surface of the magnetic plate 25, preventing the accumulation of impurities from affecting the magnetic separation effect. The scraped impurities are collected at the bottom of the magnetic cylinder 11. The discharge pipe 21 discharges the material. The screening box 1 is equipped with multi-group grading screens 18. The screens are connected to the sliding groove 14 via the slider 15, which has good support stability and adjustability. The aluminum powder raw material is graded according to particle size in the screening box 1 by the vibration or gravity of the screens. Fine powder passes through the screens and enters the next stage of processing, while coarse particles and impurities are trapped on the screen surface. The upper surface of the fixing block 27 is connected to the limiting block 7, and the bottom surface of the limiting block 7 is connected to the disassembly fixing column 17, which passes through the fixing block 27 and the connecting plate 13, so as to facilitate quick disassembly and replacement of the grading screens 18 and reduce maintenance difficulty. The screened aluminum powder raw material is collected by the collection plate 19 on the bottom surface of the screening box 1 and transported to the next process through the discharge pipe 20.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
