[0002] Aluminum ash, the scum produced during the production of molten aluminum ingots, contains significant amounts of metallic aluminum and its compounds, and possesses high recycling value. Based on its generation and processing steps, aluminum ash is divided into primary aluminum ash and secondary aluminum ash. The former originates from electrolytic aluminum production, while the latter is the residue after primary aluminum ash recovery, still containing metallic aluminum and other valuable elements. Through methods such as ash roasting recovery, tilting rotary kiln processing, pressing recovery, gravity separation, electrostatic separation, centrifugation, and mechanical screening, valuable resources can be recovered from secondary aluminum ash, reducing waste, lowering dependence on virgin materials, and promoting sustainable resource utilization.

DETAILED DESCRIPTION

[0031] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0032] An aluminum particle recovery device for aluminum ash resource utilization, such as Figure 1-Figure 3As shown, it includes a frame 1, a processing bin 2, a ball mill 3, a dust collector 4, a dust removal mechanism, a secondary grinding mechanism and a feeding mechanism. The processing bin 2 is connected in the middle of the frame 1, and the ball mill 3 is installed on the top right side of the frame 1. The discharge end of the ball mill 3 is connected to the top right side of the processing bin 2. The dust collector 4 is installed on the top left side of the frame 1. The dust collector 4 is provided with a dust removal mechanism. The processing bin 2 is provided with a secondary grinding mechanism and a feeding mechanism for conveying materials.

[0033] like Figure 2 and Figure 3 As shown, the dust removal mechanism includes a dust suction pipe 51, a dust suction frame 1 52 and a dust suction frame 2 53. The dust suction end of the dust collector 4 is installed with a dust suction pipe 51, and the lower part of the dust suction pipe 51 extends into the processing chamber 2. The right side of the dust suction pipe 51 extending into the processing chamber 2 is installed with a dust suction frame 1 52, and the left side of the dust suction pipe 51 extending into the processing chamber 2 is installed with two front and rear dust suction frames 2 53.

[0034] like Figure 2 and Figure 3 As shown, the secondary grinding mechanism includes a partition plate 61, a guide frame 62, a dual-axis motor 63, a grinding block 64, a blocking plate 65, a guide tube 66 and a discharge tube 67. The middle of the processing chamber 2 is connected to the partition plate 61, and the guide frame 62 is connected to the lower part of the processing chamber 2. The partition plate 61 is located in the middle of the guide frame 62 to divide the inside of the guide frame 62 into left and right sides. The processing chamber 2 is a V-shaped structure with the lower part gradually shrinking to form a grinding chamber 621. The bottom of the processing chamber 2 is A dual-axis motor 63 is installed in the chamber, and a grinding block 64 is connected to the output shaft above the dual-axis motor 63. The grinding block 64 is located in the grinding chamber 621 and fits against the lower part of the processing chamber 2. A blocking plate 65 is connected between the left side of the partition plate 61 and the left side of the guide frame 62. A guide tube 66 is connected to the bottom of the guide frame 62, and a discharge pipe 67 is connected to the left side of the guide frame 62. The discharge pipe 67 is located on the upper part of the blocking plate 65, and the front side of the discharge pipe 67 passes through the processing chamber 2.

[0035] like Figure 2 and Figure 3 As shown, the feeding mechanism includes a guide tube 71, a spiral conveying shaft 72, a belt drive group 73 and a diverter frame 74. The guide tube 71 is connected to the left side of the processing bin 2. The lower part of the guide tube 71 is connected to the guide tube 66 so that the guide tube 66 can feed the material in the guide frame 62 into the guide tube 71. The guide tube 71 is rotatably connected with the spiral conveying shaft 72. A belt drive group 73 is provided between the spiral conveying shaft 72 and the output shaft below the dual-axis motor 63 to realize the transmission connection between the dual-axis motor 63 and the spiral conveying shaft 72 through the belt drive group 73. The diverter frame 74 is connected to the front and rear sides of the upper part of the guide tube 71.

[0036] When aluminum ash needs to be processed, the recovery device can be used for processing. During the processing, the aluminum ash is put into the ball mill 3, and the ball mill 3 is controlled to grind the aluminum ash. The ground metal aluminum and impurities are sent to the processing bin 2 together. At this time, the dust collector 4 can be operated to generate negative pressure in the dust collection frame 52 to suck away the impurities. Since the aluminum particles are plastic, they will be squeezed and enlarged during the grinding process instead of being crushed. Therefore, it is only necessary to control the airflow during dust collection to achieve the effect of absorbing only impurities but not aluminum particles. The ground aluminum particles will then fall on the grinding block 64 at the lower part of the guide frame 62. At this time, the dual-axis motor 63 is controlled to operate to drive the grinding block 64 to rotate and cooperate with the grinding chamber 621 to grind the aluminum particles for the second time. The second-ground aluminum particles will pass through the grinding chamber 6 21 and the guide tube 66 enter the guide tube 71, and when the dual-axis motor 63 is started, it can also drive the spiral conveying shaft 72 to rotate through the belt drive group 73. The spiral conveying shaft 72 can convey the aluminum particles in the guide tube 71 upward when rotating. When the aluminum particles are conveyed to the top of the guide tube 71, the aluminum particles will fall to the diversion frames 74 on both sides of the upper part of the guide tube 71, and the aluminum particles will be diverted by the diversion frames 74. At this time, the dust collection frame 2 53 can suck away the impurities again to achieve the effect of secondary screening. The processed aluminum particles fall on the baffle plate 65 on the left side of the guide frame 62, and slide along the baffle plate 65 to the discharge pipe 67, and are discharged through the discharge pipe 67. In this way, the effect of resource processing of aluminum ash can be achieved, and in the process of processing, it can be ground and sorted for the second time to ensure the effect of aluminum ash processing.

[0037] like Figure 4 and Figure 5 As shown, it also includes a breaking up mechanism, which includes a side plate 81, a movable frame 82, a driving cylinder 83, a swinging plate 84 and an extension shaft 85. The side plate 81 is installed at the middle position of the upper right side wall of the processing chamber 2, and the driving cylinder 83 is installed at the front position of the upper right side wall of the processing chamber 2. The telescopic rod of the driving cylinder 83 is connected to the movable frame 82, and the swinging plate 84 is hingedly connected at even intervals on the left side of the side plate 81. The right side of the movable frame 82 is evenly spaced with a number of receiving grooves that is the same as the swinging plate 84. An extension shaft 85 is provided on the lower left side of the swinging plate 84, and the extension shaft 85 is located in the receiving groove. The swinging plate 84 is located below the connection position between the ball mill 3 and the processing chamber 2, so that the aluminum particles entering from the ball mill 3 can fall to the swinging plate 84.

[0038] When the aluminum particles enter the processing bin 2, they fall down and land between multiple swing plates 84. Before that, the driving cylinder 83 can be controlled to drive the mobile frame 82 to move back and forth. When the mobile frame 82 moves, it can drive the extension shaft 85 to move together. When the extension shaft 85 moves, it can drive the left side of the swing plate 84 to move together. Since the right side of the swing plate 84 is hingedly connected to the side plate 81, the swing plate 84 can swing repeatedly along its hinge point. During the swinging process of the swing plate 84, the distance between the two adjacent swing plates 84 gradually decreases, thereby squeezing the aluminum particles and breaking up the aluminum particles that are stuck together, so as to avoid the aluminum particles sticking together and affecting the sorting of impurities.

[0039] like Figure 6 As shown, it also includes a magnetic attraction mechanism, which includes a guide frame 91, a collecting frame 92, a servo motor 93 and a cylindrical magnet 94. The guide frame 91 is connected to the top right side of the processing chamber 2, and the guide frame 91 is located below the connection position between the ball mill 3 and the processing chamber 2, and is used to guide the aluminum particles entering the processing chamber 2. A servo motor 93 is installed on the upper right side of the processing chamber 2, and a cylindrical magnet 94 is connected to the output shaft of the servo motor 93. The cylindrical magnet 94 penetrates into the processing chamber 2 and is located below the guide frame 91. The cylindrical magnet 94 is in contact with the side wall of the processing chamber 2. The collecting frame 92 is connected to the upper right side of the processing chamber 2, and the collecting frame 92 is located below the cylindrical magnet 94.

[0040] The aluminum particles entering the processing chamber 2 from the ball mill 3 will be guided by the guide frame 91 and then fall down. At this time, the cylindrical magnet 94 can be controlled to absorb the magnetic metal impurities such as iron filings contained in the aluminum particles. As the cylindrical magnet 94 rotates, the cylindrical magnet 94 can contact the side wall of the processing chamber 2, thereby scraping the metal impurities attached to the cylindrical magnet 94 through the side wall of the processing chamber 2 into the collecting frame 92. The metal impurities are collected by the collecting frame 92, and thus the sorting and processing of the metal impurities can be achieved.

[0041] like Figure 7 and Figure 8 As shown, a scraping mechanism is also included, and the scraping mechanism includes a sliding frame 101, a scraper 102 and a scraper 2 103. The sliding frame 101 is slidably connected to the partition plate 61, and the sliding frame 101 can slide back and forth along the partition plate 61. A plurality of scrapers 102 are connected to the right side of the sliding frame 101, and the scraper 102 is in contact with the dust collection surface of the dust collection frame 1 52. The sliding frame 101 is connected to the movable frame 82, and two scrapers 2 103 are connected to the left side of the sliding frame 101, and the two scrapers 2 103 are respectively in contact with the dust collection surfaces of the two dust collection frames 2 53.

[0042] When the movable frame 82 moves, it can drive the sliding frame 101 to move forward and backward. When the sliding frame 101 moves forward and backward, it can drive the scraper 102 and the scraper 2 103 to move forward and backward. The scraper 102 and the scraper 2 103 can scrape off the dust attached to the surface of the dust collection frame 1 52 and the dust collection frame 2 53 during the movement. While the dust is being scraped off, the dust collection frame 1 52 and the dust collection frame 2 53 are still in the dust collection state, and can absorb the scraped dust into the dust collection frame 1 52 and the dust collection frame 2 53, thereby achieving the function of removing the dust.

[0043] like Figure 9 As shown, a scraper plate 11 is also included. The scraper plate 11 is connected to the output shaft above the dual-axis motor 63. The scraper plate 11 is in contact with the inner bottom surface of the grinding chamber 621. During the grinding process, some aluminum particles will fall on the bottom of the grinding chamber 621. When the dual-axis motor 63 is in operation, it can drive the scraper plate 11 to rotate, and the aluminum particles that fall on the bottom of the grinding chamber 621 are scraped into the guide tube 66 to prevent the aluminum particles from being stuck at the bottom of the grinding chamber 621.

[0044] This embodiment also provides a method for recovering aluminum particles from aluminum ash, and the specific steps are as follows:

[0045] S1: Aluminum ash is put into the ball mill 3, and the ball mill 3 is controlled to grind the aluminum ash. The ground aluminum metal and impurities are sent to the processing chamber 2;

[0046] S2: The dust collector 4 operates, generating negative pressure in the dust collecting frame 1 52, sucking away impurities. The ground aluminum particles fall onto the grinding block 64 at the lower portion of the guide frame 62.

[0047] S3: Control the dual-axis motor 63 to drive the grinding block 64 to rotate and cooperate with the grinding chamber 621 to perform secondary grinding on the aluminum particles. The secondary ground aluminum particles will pass through the grinding chamber 621 and the guide tube 66 and enter the guide tube 71;

[0048] S4: When the dual-axis motor 63 is started, the spiral conveying shaft 72 is driven to rotate through the belt drive group 73. When the spiral conveying shaft 72 rotates, it can convey the aluminum particles in the guide tube 71 upward. When the aluminum particles are conveyed to the top of the guide tube 71, the aluminum particles will fall to the diversion frames 74 on both sides of the upper part of the guide tube 71. The aluminum particles are diverted by the diversion frames 74, and the dust collection frame 53 can suck away the impurities again for secondary screening;

[0049] S5: The processed aluminum particles fall onto the blocking plate 65 on the left side of the guide frame 62, and slide along the blocking plate 65 to the discharge pipe 67, and are discharged through the discharge pipe 67, thereby completing the processing of the aluminum ash.

[0050] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to be illustrative only and not to limit the present invention, which is to be defined by the claims.
