Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] See Figure 1 This is one embodiment of a magnetic separation filtration device according to the present invention.

[0033] Includes a machine body 1, a feeding hopper 9 is provided at the upper end of the machine body 1, a primary magnetic separator 2 is provided inside the machine body 1, and a first channel 3 for outputting magnetic materials and a second channel 4 for outputting non-magnetic materials are also provided inside the machine body 1.

[0034] The primary magnetic separator 2 includes a first rotating drum 21, inside which are arranged multiple fixed first magnetic strips 22, with the first magnetic strips 22 evenly distributed in half a circle around the circumference.

[0035] When using this device, the iron-aluminum mixed powder is placed into the feeding hopper 9, where it falls onto the primary magnetic separator 2. The first magnetic strip 22 on the primary magnetic separator 2 adsorbs some of the iron powder, thus removing some of the iron powder from the iron-aluminum mixed powder and achieving aluminum powder sieving. However, to ensure continuous separation of the iron-aluminum mixed powder, this device incorporates a new structure, as detailed below:

[0036] The first rotating cylinder 21 is provided with a first mounting bracket 23 at both ends, a first mounting hole 24 in the middle of the first mounting bracket 23, a first bearing 26 in the first mounting hole 24, a first mounting shaft 27 in the first bearing 26, a first connecting plate 28 on the first mounting shaft 27, and the first connecting plate 28 is fixed together with the first magnetic strip 22.

[0037] A first fixed cylinder 29 is provided on the outer side of the first mounting bracket 23, and a first driving device 5 is provided on the first fixed cylinder 29. The first driving device 5 includes a first driven gear 51 provided on the outer periphery of the first fixed cylinder 29, a first driving gear 52 meshing on the first driven gear 51, and a first motor 53 connected in the middle of the first driving gear 52.

[0038] The first magnetic strip 22 in this device is fixed in position and is connected to the first mounting shaft 27 through the first connecting plate 28. The first mounting shaft 27 does not rotate, and the end of the first mounting shaft 27 is fixed to the body 1.

[0039] When the first motor 53 is working, it drives the first driving gear 52 to rotate, the first driving gear 52 drives the first driven gear 51 to rotate, and the first driven gear 51 drives the first fixed cylinder 29 to rotate, and the first fixed cylinder 29 drives the first mounting bracket 23 to rotate, thereby realizing the rotation of the first fixed cylinder 29.

[0040] At this time, the first mounting shaft 27 will not rotate when the entire first rotating cylinder 21 rotates, as the first bearing 26 provided in the first mounting hole 24 passes through it. The iron powder in the iron-aluminum mixture will be attracted to the first rotating cylinder 21 by the magnetic force of the first magnetic strip 22 and will move with the rotation of the first rotating cylinder 21. When it moves to a position where there is no first magnetic strip 22, the iron powder will slide off the first rotating cylinder 21 and fall into the first channel 3.

[0041] Since the aluminum powder in the iron-aluminum mixture is not attracted by the first magnetic strip 22, it enters the second channel 4 as the first rotating drum 21 rotates and generates centrifugal force; at this time, the separation of iron powder and aluminum powder in the iron-aluminum mixture can be achieved.

[0042] However, in actual use, the iron-aluminum mixed powder is not completely separated, and some iron powder is still mixed in with the aluminum powder. Therefore, in order to improve the separation efficiency, this device is also equipped with a secondary magnetic separation device 6.

[0043] The secondary magnetic separator 6 is located diagonally below the primary magnetic separator 2. The secondary magnetic separator 6 includes a second rotating drum 61, a driven drum 62, and a conveyor belt 63 located between the second rotating drum 61 and the driven drum 62.

[0044] The second rotating cylinder 61 has second magnetic strips 64 evenly distributed around its inner circumference. The second rotating cylinder 61 has second mounting brackets 65 at both ends. The second mounting brackets 65 have a second mounting hole 66 in the middle. The second mounting hole 66 has a second bearing 67 inside. The second bearing 67 has a second mounting shaft 68 inside. The second mounting shaft 68 has a second connecting plate 69 mounted on it. The second connecting plate 69 is fixed together with the second magnetic strips 64.

[0045] A second drive device 7 is provided on the outer side of the second mounting bracket 65. The second drive device 7 includes a second fixed cylinder 71 fixed on the second mounting bracket 65. A second driven gear 72 is provided on the second fixed cylinder 71. A second driving gear 73 meshes with the second driven gear 72. A second motor 74 is connected in the middle of the second driving gear 73.

[0046] A third drive device 8 is provided at the end of the second mounting shaft 68. The third drive device 8 includes a third driven gear 81 that is keyed to the second mounting shaft 68. A third drive gear 82 meshes with the third driven gear 81. A third motor 83 is connected in the middle of the third drive gear 82.

[0047] The structure of the secondary magnetic separator 6 is similar to that of the primary magnetic separator 2. The difference is that the diameter of the second rotating drum 61 in the secondary magnetic separator 6 is smaller, and the second magnetic strips 64 are evenly distributed around the circumference of the second rotating drum 61. At the same time, both the second magnetic strips 64 and the second rotating drum 61 will rotate, and the directions of rotation are opposite.

[0048] This configuration is primarily designed to accelerate the separation of the iron-aluminum mixed powder. Specifically, during operation, the second drive device 7 operates, and the second motor 74, through the meshing of the second driving gear 73 and the second driven gear 72, drives the second fixed cylinder 71 to rotate, thereby driving the second rotating cylinder 61 to rotate. Simultaneously, the third motor 83 in the third drive device 8 operates, and through the meshing of the third driven gear 81 and the third driving gear 82, drives the second mounting shaft 68 to rotate. Then, the second mounting shaft 68, through the second connecting disc 69, drives the second magnetic strip 64 to rotate in the opposite direction.

[0049] The first channel 3 is located below the primary magnetic separator 2 and the secondary magnetic separator 6; the second channel 4 is located at the output end of the secondary magnetic separator 6.

[0050] The iron-aluminum mixed powder falling into the secondary magnetic separator 6 will move along the conveyor belt 63 under the attraction of the second magnetic strip 64 until the conveyor belt 63 transports the iron powder to the top of the first channel 3 and finally falls into the first channel 3; while the aluminum powder will be thrown to the second channel 4 under the force of the conveyor belt 63, at which point the secondary separation is completed.

[0051] This device can be equipped with multiple secondary magnetic separation devices 6 to achieve multiple separations, which can thoroughly separate iron powder and aluminum powder.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
