[0052] Referring to Figure 1 、 Figure 2 and Figure 3 As shown in

[0053] In one embodiment, as Figure 3As shown, the disk group 13 may include a plurality of first disks 131 and a plurality of second disks 132, and the first disks 131 and the second disks 132 are alternately stacked and installed on the shaft tube 12; the first disks 131 may include a plurality of concentrically arranged annular first magnetic strips 1311; the second disks 132 may include a plurality of concentrically arranged annular second magnetic strips 1321; the second magnetic strips 1321 are located below the gaps between two adjacent first magnetic strips 1311. The annular magnetic strip design does not have as many nodes as the linear magnetic strips that cross each other, reducing the possibility of material blockage; during the demagnetization process, after the battery powder passes through multiple turns of the first magnetic strips 1311 on the top layer, it flows into the second magnetic strips 1321 from between two adjacent first magnetic strips 1311, so that the battery powder passing through the gaps of the first magnetic strips 1311 falls on the second magnetic strips 1321; the battery powder passing through the second magnetic strips 1321 then falls downward from the gaps and falls into the first magnetic strips 1311 located below the gaps, and so on; this increases the probability of contact between the battery powder and the first magnetic strips 1311 and the second magnetic strips 1321, and improves the cleanliness of removing magnetic foreign objects in the battery powder.

[0054] In one embodiment, as Figure 4 shown, the top of the longitudinal section of the first magnetic strip 1311 may be a triangle or a trapezoid with the narrower end facing upward. The top of the longitudinal section of the second magnetic strip 1321 may be a triangle or a trapezoid with the narrower end facing upward. The tops of the first magnetic strip 1311 and the second magnetic strip 1321 are tapered, which can increase the area of the tops of the first magnetic strip 1311 and the second magnetic strip 1321, increase the contact area when the battery powder passes through the first magnetic strip 1311 and the second magnetic strip 1321, and improve the cleanliness of removing magnetic foreign objects in the battery powder. In addition, the tops of the first magnetic strip 1311 and the second magnetic strip 1321 are tapered, so that both sides of the tops of the first magnetic strip 1311 and the second magnetic strip 1321 have inclined slopes. When the battery powder passes through the first magnetic strip 1311 and the second magnetic strip 1321, it can fall along the slopes, reducing the friction between the battery powder and the tops of the first magnetic strip 1311 and the second magnetic strip 1321, enabling the battery powder to pass through the first magnetic strip 1311 and the second magnetic strip 1321 more smoothly, and reducing the possibility of blockage of the battery powder at the first magnetic strip 1311 and the second magnetic strip 1321.

[0055] In one embodiment, as Figure 5 and Figure 7 shown, the gap between the outer wall of the outermost first magnetic strip 1311 of the first disk 131 and the inner wall of the outer cylinder 10 is smaller than the diameter of the battery powder particles. The gap between the outer wall of the outermost second magnetic strip 1321 of the second disk 132 and the inner wall of the outer cylinder 10 is smaller than the diameter of the battery powder particles.

[0056] When the gap between the outer wall of the first magnetic strip 1311 on the outermost circle of the first disk 131 and the inner wall of the outer cylinder 10 is relatively large, the battery powder material falls downward from between the first magnetic strip 1311 on the outermost circle and the inner wall of the outer cylinder 10 and falls into the discharge pipe 11. And this part of the battery powder material does not pass through the disk group, that is, it directly falls into the discharge pipe 11 without being demagnetized, which affects the demagnetization effect. By controlling the gap between the magnetic strip and the inner wall of the outer cylinder, the situation where the battery powder material can avoid demagnetization is prevented, and the demagnetization effect is improved.

[0057] In one embodiment, as Figure 3 and Figure 4 shown, the first disk 131 may further include a first sleeve 1312; the first sleeve 1312 is located at the center of the first disk 131, is concentrically arranged with the first magnetic strip 1311, and is installed on the shaft tube 12; the second disk 132 may further include a second sleeve 1322, the second sleeve 1322 is located at the center of the second disk 132, is concentrically arranged with the second magnetic strip 1321, and is installed on the shaft tube 12; the first sleeve 1312 and the second sleeve 1322 are alternately installed on the shaft tube 12, so that the two ends of the first sleeve 1312 are abutted against the two ends of the second sleeve 1322 end to end. During the installation process, it is not necessary to install obliquely like the existing strip-shaped magnetic strips. As long as the first sleeve 1312 and the second sleeve 1322 are sleeved on the shaft tube 12, it is not necessary to align the distance between the strip-shaped disks like the strip-shaped disks, which simplifies the installation process and makes the installation of the first disk 131 and the second disk 132 more convenient and fast.

[0058] In one embodiment, as Figure 9 and Figure 10 shown, the disk group 13 may further include a plurality of connecting blocks 133; between two adjacent first magnetic strips 1311 and between two adjacent second magnetic strips 1321 are integrally formed or welded and fixedly connected through the connecting blocks 133.

[0059] The first sleeve 1312 and the first magnetic strip 1311 are integrally formed or welded and fixedly connected through the connecting block 133. The second sleeve 1322 and the second magnetic strip 1321 are integrally formed or welded and fixedly connected through the connecting block 133. A layer of polytetrafluoroethylene is coated on both the made first disk 131 and the second disk 132 to prevent magnetic foreign matters from entering the battery powder material. The connecting block 133 fixedly connects a plurality of concentrically arranged first magnetic strips 1311 and the first sleeve 1312 together to form the first disk 131. The connecting block 133 fixedly connects a plurality of concentrically arranged second magnetic strips 1321 and the second sleeve 1322 together to form the second disk 132.

[0060] In one embodiment, as Figure 4As shown, a second air hole 13221 is formed in the second sleeve 1322, and the second air hole 13221 communicates with the shaft tube 12. A hole communicating with the second air hole 13221 is formed in the shaft tube 12 corresponding to the second air hole 13221, so that the positive pressure transmitted from the positive pressure machine 14 in the shaft tube 12 can be transmitted into the outer cylinder 10, forming an air pressure difference from top to bottom in the outer cylinder 10, making it easier for the battery powder in the outer cylinder 10 to fall from top to bottom and reducing the possibility of blockage of the battery powder in the outer cylinder 10.

[0061] In one embodiment, as Figure 9 、 Figure 10 、 Figure 11 shown, guide bars 122 are provided on the outer wall of the shaft tube 12, and a first guide groove 13121 and a second guide groove 13222 adapted to the guide bars 122 are respectively formed inside the first sleeve 1312 and the second sleeve 1322, and the guide bars 122 can slide in the first guide groove 13121 and the second guide groove 13222.

[0062] As Figure 6 and Figure 8 shown, when installing the first disk 131, after aligning the first guide groove 13121 with the guide bar 122, the first sleeve 1312 is sleeved on the shaft tube 12. When installing the second disk 132, after aligning the second guide groove 13222 with the guide bar 122, the second sleeve 1322 is sleeved on the shaft tube 12. After alignment during the installation process, there is no need to rotate and adjust the angles of the first disk 131 and the second disk 132, making the installation of the first sleeve 1312 and the second sleeve 1322 accurate, fast and simple.

[0063] In one embodiment, as Figure 2 and Figure 3 shown, the battery powder separator further includes a flap valve 16; the discharge pipe 11 includes a battery powder discharge pipe 111 and a magnetic material discharge pipe 112; one end of the battery powder discharge pipe 111 is connected to the bottom of the outer cylinder 10, one end of the magnetic material discharge pipe 112 is connected to the side of the battery powder discharge pipe 111, and the flap valve 16 is arranged at the connection of the battery powder discharge pipe 111 and the magnetic material discharge pipe 112. The flap valve 16 includes a rotating shaft 161, a valve plate 162, a motor 163, and a sleeve 164; the sleeve 164 is fixedly arranged outside the connection of the battery powder discharge pipe 111 and the magnetic material discharge pipe 112, the center line of the sleeve 164 is perpendicular to the plane formed by the center line of the battery powder discharge pipe 111 and the center line of the magnetic material discharge pipe 112, the rotating shaft 161 passes through the sleeve 164 and is rotatably connected to the sleeve 164, one end of the valve plate 162 is fixed to the rotating shaft 161, the valve plate 162 is located in the discharge pipe 11, and the motor 163 is used to drive the rotating shaft 161 to rotate.

[0064] During the demagnetization process, the motor 163 drives the rotating shaft 161 to rotate, and the valve plate 162 rotates towards the magnetic material outlet pipe 112 to block the magnetic material outlet pipe 112. The battery powder material that has been demagnetized by the disk group 13 is discharged from the battery powder outlet pipe 111. After the demagnetization is completed, the motor 163 drives the rotating shaft 162 to rotate away from the magnetic material outlet pipe 112, so that the valve plate 162 blocks the battery powder outlet pipe 111, and the magnetic foreign matters on the disk group 13 flow out from the magnetic material outlet pipe 112.

[0065] Working process:

[0066] The battery powder enters the outer cylinder 10 from the top and falls downward inside the outer cylinder. During the process of the battery powder falling inside the outer cylinder 10, the other end of the shaft tube 12 is connected to the positive pressure machine 14, and the discharge pipe 11 is connected to the negative pressure machine 15; the electromagnetic powder passes through the first disk 131 and then falls onto the second magnetic strip 1321 from between two adjacent first magnetic strips 1311. The battery powder then falls from two adjacent second magnetic strips 1321 onto the first magnetic strip 1311 below, and so on, until the battery powder falls into the discharge pipe 11.

[0067] Beneficial effects:

[0068] 1. The air pressure is pressurized by the positive pressure machine 14 and introduced into the interior of the outer cylinder 10 through the shaft tube 12. At the same time, the discharge pipe 11 is connected to the negative pressure machine 15, increasing the pressure difference between the upper and lower parts inside the outer cylinder 10. During the iron removal process, the battery powder on the disk group 13 has a downward pressure under the action of the pressure difference, making it easier for the battery powder to fall off the disk group 13 and reducing the possibility of blockage of the battery powder on the disk group.

[0069] 2. The design of the annular magnetic strip does not have as many nodes as the linear magnetic strips that cross each other vertically and horizontally, reducing the possibility of material blockage; during the demagnetization process, the battery powder falls from the first magnetic strip 1311 onto the second magnetic strip 1321; the battery powder passing through the second magnetic strip 1321 continues to fall downward from the gap and falls onto the first magnetic strip 1311 below the gap, and so on; increasing the probability of contact between the battery powder and the first magnetic strip 1311 and the second magnetic strip 1321, improving the cleanliness of removing magnetic foreign matters in the battery powder. At the same time, the battery powder falls downward through the gap, reducing the possibility of blockage of the battery powder.

[0070] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
