[0002] Aluminum molten metal removal is a crucial step in aluminum processing, aiming to remove gaseous and solid inclusions from the molten aluminum to improve the quality of aluminum products. There are various methods for removing impurities, and filtration is a particularly important step in aluminum molten metal removal. Filtration is widely used to remove impurities due to its low cost.

[0003] However, using filtration methods has the following problems: workers need to replace the filter plates regularly. When replacing the filter plates, workers need to stop the machine and put their hands into the filter tank to replace them. During the replacement process, the safety of workers cannot be guaranteed.

[0046] 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.

[0047] Reference Figure 1 , Figure 2 Figure 3 and Figure 4 A device for removing impurities from molten aluminum for waste aluminum recycling includes a housing 1. It is worth noting that the housing 1 is a housing specifically for removing impurities from molten aluminum, which is existing technology and will not be described in detail here.

[0048] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7The filter element 2 includes a rotating frame 21 disposed within the housing 1. Notably, the rotating frame 21 has a U-shaped cross-section, and its side walls have multiple strip-shaped openings for storing foam ceramic filter plates 22. Multiple foam ceramic filter plates 22 are placed within the rotating frame 21, and each foam ceramic filter plate 22 has multiple fixing holes 23. A limiting bracket 24 is provided at the connection point between the multiple foam ceramic filter plates and the rotating frame 21. Notably, the limiting bracket 24 can fix the foam ceramic filter plates 22 to the rotating frame 21 using fixing screws 25. The multiple limiting frames 24 are threaded with multiple fixing screws 25 that are threaded to the rotating frame 21. At the same time, an inner liner is fixedly connected to the inner wall of the strip-shaped opening used to store the foam ceramic filter plate 22 to protect the foam ceramic filter plate 22 and further extend its service life. Meanwhile, the limiting frames 24 are equipped with high-temperature resistant sealing strips for sealing. The high-temperature resistant sealing strips are located at the connection between the foam ceramic filter plate 22 and the rotating frame 21, thereby further ensuring that the aluminum liquid can flow down from the foam ceramic filter plate 22 instead of flowing out from other positions.

[0049] Reference Figure 5 , Figure 6 and Figure 7 The housing 1 is equipped with a first annular guide rail 211. Multiple first support rods 212 connected to the rotating frame 21 are mounted on the first annular guide rail 211. These first support rods 212 support the rotating frame 21. A first gear 213 is mounted on the rotating frame 21. Above the first gear 213 is a second gear 214 meshing with it. A first motor 215 is located on one side of the second gear 214. The drive shaft of the first motor 215 is connected to the side wall of the second gear 214. When the first motor 215 operates, it rotates the drive shaft, which in turn rotates the second gear 214, thereby enabling… The rotation of the first gear 213 further enables the rotation of the rotating frame 21, allowing different foam ceramic filter plates 22 to be positioned above the housing 1, facilitating the replacement of the foam ceramic filter plates 22 by the staff. A second annular guide rail 216 is installed on the side wall of the housing 1, and multiple second support rods 217 are mounted on the second annular guide rail 216. One end of each second support rod 217 is fixedly connected to the same rotating disk 218. Notably, the rotating disk 218 is fitted onto the rotating frame 21, and the cooperation of the second support rods 217 and the first support rod 212 effectively supports the rotating frame 21, further ensuring the normal operation of the rotating frame 21 and the foam ceramic filter plates 22.

[0050] Reference Figure 7 , Figure 8 and Figure 9The housing 1 contains a conveying component 3, which includes a conveying pipe 31 disposed within the housing 1. Notably, both ends of the conveying pipe 31 extend to the outside of the housing 1. The conveying pipe 31 is situated within a rotating frame 21, and a discharge pipe 32 is installed at the output end of the conveying pipe 31. A rotating rod 33 is rotatably connected within the conveying pipe 31. Notably, a strip-shaped opening is provided at the top of the conveying pipe 31, allowing other impurities to enter the conveying pipe 31. A auger conveying blade 34 is mounted on the rotating rod 33. A transmission assembly 35, connected to the rotating rod 33, is located on one side of the conveying pipe 31. Notably, the transmission assembly 35 includes two sprockets and a chain, with one sprocket connected to the rotating rod 33. A second motor 36 is connected to one side of component 5. The drive shaft of the second motor 36 is connected to another sprocket in the transmission assembly 35. Therefore, when the second motor 36 is working, it can make the other sprocket rotate. With the assistance of the chain, one of the sprockets can rotate, which can make the rotating rod 33 rotate, thereby making the auger conveyor blade 34 rotate. This further enables impurities and waste to be transported out and discharged from the discharge pipe 32. It is worth noting that the staff can install a guide platform at the output end of the discharge pipe 32, which can further facilitate the staff to clean up impurities and waste, and indirectly improve the staff's work efficiency.

[0051] Reference Figure 9 and Figure 10 Multiple inclined guide members 4 are installed on the rotating frame 21. Notably, the multiple guide members 4 separate the multiple foam ceramic filter plates 22, further accommodating the use of different foam ceramic filter plates 22. Each guide member 4 includes a guide plate 41 fixedly connected to the rotating frame 21. Specifically, there are four guide plates 41, all located diagonally opposite each other on the rotating frame 21. Furthermore, the output ends of two adjacent guide plates 41 are positioned on either side of the strip-shaped opening of the conveying pipe 31, further enabling impurities to enter the conveying pipe 3 with the assistance of the guide plates 41. One end of each guide plate 41 is inlaid with multiple [features related to the conveying pipe]. The ball bearings 42 in contact with the tube 31 are all covered with a high-temperature resistant layer 43. One end of the guide plate 41 is fixedly connected to two symmetrical baffles 44. One end of each baffle 44 is fixedly connected to a blocking brush 45 that is in contact with the conveying tube 31. It is worth noting that part of the blocking brush 45 is hard, while the part in contact with the conveying tube 31 is soft, which further ensures the normal use of the conveying tube 31. It is also worth noting that the blocking brush 45 is made of high-temperature resistant material. Although it is called a brush, it is actually a curtain made of high-temperature resistant material, which further prevents impurities from contacting the ball bearings 42, thereby protecting the ball bearings 42.

[0052] Reference Figure 9 , Figure 10 and Figure 11 The guide plate 41 consists of two heat-conducting steel plates 411 and a sealing block 412. The two heat-conducting steel plates 411 are symmetrically arranged and connected by the sealing block 412. The sealing block 412 is made of high-temperature resistant material, which is existing technology and will not be described in detail here. Meanwhile, ball bearings 42 are embedded in the sealing block 412. Multiple heat-conducting arc-shaped plates 413 are fixedly connected to both heat-conducting steel plates 411. The cross-section of the multiple heat-conducting arc-shaped plates 413... All are arc-shaped, and the arc surfaces of multiple heat-conducting arc-shaped plates 413 all face the heat-conducting steel plate 411. Two heat-conducting arc-shaped plates 413 are connected by heat-conducting rods 414. Each heat-conducting rod 414 is fitted with an insulation cylinder 415. It is particularly noteworthy that the insulation cylinder 415 is made of insulation material, and adjacent heat-conducting rods 414 are connected by conductive rods 416. It is particularly noteworthy that the material of the conductive rods 416 is the same as that of the heat-conducting rods 414, thus... It can effectively conduct heat. Of particular note is that when the molten aluminum is on the bottom foam ceramic filter plate 22, the heat-conducting arc plate 413 absorbs the heat emitted by the molten aluminum. At this time, the heat-conducting rod 414 transfers the heat from one heat-conducting arc plate 413 to another. The insulation cylinder 415 and the conductive rod 416 provide insulation and heat conduction, further ensuring heat transfer and indirectly improving heat utilization. This allows the other heat-conducting steel plate 411 to release heat, preheating the other foam ceramic filter plate 22, making it ready for direct use. This eliminates the need for preheating, reducing workload and indirectly improving the filtration efficiency of the molten aluminum.

[0053] Reference Figure 12 and Figure 13The housing 1 is equipped with a conveyor 5, which includes a conveyor plate 51 fixedly connected to the inner wall of the housing 1. Notably, one end of the conveyor plate 51 is fixedly connected to a first heat insulation plate 52 connected to the housing 1. Furthermore, the output end of the conveyor plate 51 is located below the foam ceramic filter plate 22. After the molten aluminum is filtered by the foam ceramic filter plate 22, it falls onto the conveyor plate 51. The first heat insulation plate 52 serves to insulate against heat, further preventing heat from the conveyor plate 51 from being transferred to the bottom of the rotating disk 218, thus protecting the rotating disk 218. A baffle plate 53 is fixedly connected to the feeding plate 51. The baffle plate 53 is located at the output port of the housing 1. A second heat insulation plate 54 is fixedly connected to the side wall of the housing 1. The second heat insulation plate 54 is located below the first gear 213, which further protects the first gear 213. At the same time, a conveying channel 55 is installed at the input end of the housing 1. The conveying channel 55 is connected to the external aluminum liquid processing production line. The output end of the conveying channel 55 extends into the interior of the housing 1 and is located in the rotating frame 21. An output channel 56 is installed at the output end of the housing 1. The output end of the feeding plate 51 is located on one side of the output channel 56.

[0054] Reference Figure 14 Two symmetrical preheating components 6 are installed on the side wall of the housing 1. The preheating component 6 includes a preheating box 61 fixedly connected to the inner side wall of the housing 1. The preheating box 61 is provided with an air outlet plate 62 connected to an external air pump. Multiple electric heating tubes 63 are provided on one side of the air outlet plate 62. Multiple air outlets 64 are provided on the side wall of the preheating box 61. Multiple air outlets 64 are located on one side of multiple electric heating tubes 63. Heat absorption plates 65 are fixedly connected to the inner side wall of multiple air outlets 64. The two preheating boxes 61 are respectively located on one side of two foam ceramic filter plates 22.

[0055] Reference Figure 7 and Figure 15One of the foam ceramic filter plates 22 has multiple fasteners 7 above it. Each fastener 7 includes a fastening plate 71 positioned above the foam ceramic filter plate 22. The lower end of the fastening plate 71 is fixedly connected to a fastening post 72 that matches the fastening hole 23. The fastening plate 71 has a placement hole 73, through which a screw 74 passes. The inner top end of the fastening post 72 is fixedly connected to a nut 75 threadedly connected to the screw 74. Multiple through holes 76 are provided through the side wall of the fastening post 71. Limiting collars 77 are fixedly connected to the inner side walls of each of the multiple through holes 76. Spring seats 78 are fixedly connected to the side walls of ring 77. It is particularly noteworthy that spring seats 78 include springs and movable seats that match through holes 76. The springs are connected to limiting collars 77. A locking rod 79 is provided through spring seats 78. One end of locking rod 79 passes through limiting collars 77 and extends to the outside of fixed post 72. One end of locking rod 79 is sharp. Movable seats are sleeved on locking rod 79. One end of locking rod 79 is fixedly connected to an arc-shaped ball 710 that contacts screw 74. A rotating seat 711 that contacts screw 74 is connected to the inner bottom of fixed post 72.

[0056] When the device starts operating, the externally treated molten aluminum first enters the rotating frame 21 through the conveying channel 55. It is important to note that one end of the conveying channel 55 extends into the rotating frame 21, and the rotation of the rotating frame 21 does not affect the normal operation of the conveying channel 55. The guide plate 44 does not contact the conveying channel 55, therefore, the guide plate 44 does not affect the normal operation of the conveying channel 55. When the molten aluminum enters the rotating frame 21, it comes into contact with the foam ceramic filter plate 22. Then, under the influence of gravity, the molten aluminum filters the foam ceramic filter plate 22, and then the molten aluminum enters the conveying plate 51. It is particularly important to note that the conveying plate... The aluminum liquid is tilted at 51, allowing it to enter the output port of the housing 1 and then flow into the output channel 56. The filtered aluminum liquid then proceeds to the next processing step. During this process, it is particularly important that the first heat insulation plate 52 prevents heat from the conveyor plate 51 from being transferred to the bottom of the rotating disk 218, thus protecting the rotating disk 218. The second heat insulation plate 54 prevents heat from being transferred to the first gear 213, further protecting the first gear 213. The baffle plate 53 effectively prevents aluminum liquid from leaking out, ensuring proper filtration of the aluminum liquid and enabling the device to operate normally.

[0057] When the operator needs to replace the foam ceramic filter plate 22, they can directly start the first motor 215. When the first motor 215 is working, it will cause the second gear 214 to rotate, which in turn will cause the first gear 213 to rotate, thereby causing the rotating frame 21 to rotate. It is particularly noteworthy that, with the assistance of the first support rod 212, the first annular guide rail 211, the second support rod 217, the second annular guide rail 216, and the rotating disk 218, the rotating frame 21 can rotate more stably, further allowing the foam ceramic filter plate 22, which is at the bottom, to rotate to the top. After waiting for a period of time, the operator can then insert the fixing post 72 into the fixing hole 23, and then... Rotate screw 74 into placement hole 73, allowing screw 74 to move along the thread direction of nut 75. This causes screw 74 to move downwards, compressing the arc-shaped ball 710 and causing clamping rod 79 to move to one side. The movement of clamping rod 79 allows one end of clamping rod 79 to engage with the side wall of fixing hole 23. Then, the operator rotates fixing screw 25, allowing the limit bracket 24 to be removed. The operator then ties rope to fixing column 72 and starts external hoisting equipment, allowing foam ceramic filter plate 22 to be removed from rotating frame 21, further facilitating the replacement of foam ceramic filter plate 22 and simplifying the replacement process.

[0058] It is particularly noteworthy that when replacing the foam ceramic filter plate 22, the operator can gently tap the foam ceramic filter plate 22. At this time, the impurities adhering to the foam ceramic filter plate 22 will fall off due to gravity. This allows the impurities to enter the strip opening on the conveying pipe 31 with the assistance of the guide plate 41. At this time, the second motor 36 works. When the second motor 36 works, with the assistance of the transmission component 35, the rotating rod 33 can rotate, which in turn can rotate the auger conveying blade 34, thereby allowing the impurities to be conveyed to the discharge pipe 32. This makes it easier for the operator to clean the impurities and further avoids the aluminum liquid from being contaminated.

[0059] Of particular note is that when the guide plate 41 rotates, the ball bearings 42 ensure the normal rotation of the guide plate 41, while the blocking brush 45 prevents impurities from adhering to the ball bearings 42. Also noteworthy is that the heat-conducting arc-shaped sheet 413 on the lower heat-conducting steel plate 411 absorbs the temperature emitted by the molten aluminum. With the assistance of the heat-conducting rod 414, the insulation cylinder 415, and the conduction rod 416, heat can be transferred to another part of the heat-conducting steel plate 411, thus preheating the other foam ceramic filter plate 22. During this process, the staff can activate the external air pump and electric heating tube 63, which allows the gas to be sprayed out from the air outlet 62. When the gas passes through the electric heating tube 63, it is heated. The heat absorption plate 65 absorbs the heat from the electric heating tube 63, which not only reheats the gas but also preheats the foam ceramic filter plate 22. This further ensures that the staff can use the foam ceramic filter plate 22, reduces the preheating time, and further improves the efficiency of installation and replacement.
