[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present application. The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. That is, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In addition, unless otherwise specified, the meaning of "a plurality" is two or more.

[0033] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0034] Such as Figures 1-7As shown in the figure, a ferromagnetic separation device for battery powder provided by an embodiment of the present application includes a machine body 1, a conveying mechanism 2, and a magnetic separation mechanism 3. The machine body 1 has an accommodation space 11 inside. One end of the machine body 1 is provided with a feed inlet 12, and the other end of the machine body 1 is provided with a first discharge outlet 13 and a second discharge outlet 14. The conveying mechanism 2 includes a motor 21 and a screw 22 driven by the motor 21. The screw 22 is arranged in the accommodation space 11 and is used to convey the battery powder from the feed inlet 12 to the first discharge outlet 13. Among them, during the process of the screw 22 conveying the battery powder, the iron powder in the battery powder is adsorbed by the electromagnetic rod 33, so that the non-magnetic substances are discharged from the first discharge outlet. The magnetic separation mechanism 3 is arranged in the accommodation space 11 and is located above the conveying mechanism 2. The magnetic separation mechanism 3 includes a conveyor belt 31, a conveyor wheel 32, an electromagnetic rod 33, and an energized guide rail 34. The conveyor belt 31 includes a first horizontal area 31a, a second horizontal area 31b, a first end area 31c, and a second end area 31d. The first horizontal area 31a is arranged above the second horizontal area 31b. The first end area 31c and the second end area 31d are respectively arranged at both ends of the first horizontal area 31a and the second horizontal area 31b and are distributed along the feeding direction of the conveying mechanism 2. The second end area 31d is arranged above the second discharge outlet 14. The conveyor wheel 32 is used to keep the conveyor belt 31 moving smoothly. One end of the electromagnetic rod 33 is installed on the surface of the conveyor belt 31, and the other end abuts against the screw 22. The energized guide rail 34 is installed on the inner wall of the machine body 1. Among them, the second horizontal area 31b is arranged opposite to the energized guide rail 34. When the screw 22 rotates, it drives the electromagnetic rod 33 and the conveyor belt 31 to move. Only the electromagnetic rod 33 in the second horizontal area 31b is electrically connected to the energized guide rail 34, and the electromagnetic rod 33 is inserted into the battery powder conveyed by the conveying mechanism 2.

[0035] During operation, battery powder is put into the machine through the feed inlet 12, and the conveying mechanism 2 is started to make the battery powder move in the accommodation space of the machine body 1. The magnetic separation mechanism 3 is started, and the conveyor wheel 32 drives the electromagnetic rod 33 on the conveyor belt 31 to move. The electromagnetic rod 33 in the second horizontal area 31b is energized with the energized guide rail 34 to generate electromagnetic force. The electromagnetic rod 33 is inserted into the battery powder conveyed by the conveying mechanism 2 to realize the adsorption of the iron powder therein. The battery powder after the iron powder is adsorbed continues to move with the conveying mechanism 2 and falls into the first discharge outlet 13. At the same time, when the electromagnetic rod 33 is driven by the screw 22 and moves into the second end area 31d along with the conveyor belt 31, the electromagnetic rod 33 is disconnected from the energized guide rail 34 and loses the electromagnetic force, so that the iron powder falls off the electromagnetic rod 33 and enters the second discharge outlet 14. It should be noted that the moving direction of the conveyor belt 31 is to move in a cycle in the first horizontal area 31a, the second horizontal area 31b, the first end area 31c, and the second end area 31d in sequence, that is, the conveyor belt 31 moves counterclockwise.

[0036] Based on the above settings, the entire magnetic separation operation process does not require shutdown operation and can work continuously, resulting in high magnetic separation efficiency.

[0037] As Figure 5 and 6 shown, in one embodiment, the electromagnetic rod 33 includes a hollow rod body 331, a coil 332 disposed inside the rod body 331, and a wire 333 connected to the coil 332. When the wire 33 is connected to a power source, the coil 332 conducts current to generate an electromagnetic force, enabling the rod body 331 to adsorb magnetic substances.

[0038] Specifically, a first conductive strip 311 is provided on the surface of the conveyor belt 31, and the first conductive strip 311 is electrically connected to the wire 333. Among them, the first conductive strip 311 includes two groups, which are respectively used as the positive and negative electrodes and are electrically connected to the corresponding wire 333, and there is a gap between the two groups of first conductive strips 311 to achieve an insulating effect and avoid short - circuit conditions.

[0039] Furthermore, on the side of the energized guide rail 34 away from the inner wall of the machine body 1, there is a conductive groove 341, and a second conductive strip 342 is provided inside the conductive groove 341. The first conductive strip 311 abuts against the second conductive strip 342. Among them, the second conductive strip 342 includes two groups, which are respectively used as the positive and negative electrodes and are electrically connected to the corresponding first conductive strip 311, and there is a gap between the two groups of second conductive strips 342 to achieve an insulating effect and avoid short - circuit conditions. During actual operation, a part of the structure of the conveyor belt 31 extends into the conductive groove 341. By keeping the contact surface between the first conductive strip 311 and the second conductive strip 342 smooth, the electromagnetic rod 33 can be energized while the conveyor belt 31 is moving.

[0040] As Figure 7 shown, in one embodiment, the energized guide rail 34 has two sections and is correspondingly disposed on both sides of the second horizontal region 31b. This facilitates the installation of as many electromagnetic rods 33 as possible and improves the efficiency of magnetic separation.

[0041] As Figures 1-3 shown, the conveying mechanism 2 further includes a stirring rod 23, and the stirring rod 23 is fixed to the screw 22 along the axial direction of the screw 22. By providing the stirring rod 23, the battery powder is stirred and fully dispersed during the transmission process, which is beneficial for the electromagnetic rod 33 to insert into the battery powder and improves the efficiency of adsorbing iron powder.

[0042] Further, the screw 22 includes a rod body 221 and a spiral blade 222 provided on the rod body 221. An air intake passage 223 is provided inside the rod body 221. Air outlet holes 224 communicating with the air intake passage 223 are provided on the surface of the screw 221. One end of the rod body 221 extends out of the machine body 1 and is connected to a positive pressure air source. During use, the gas introduced into the air intake passage 223 of the rod body 221 is discharged from the air outlet holes 224, so that the battery powder is blown up, which is more conducive to the iron powder therein being adsorbed by the electromagnetic rod 33, and the iron powder in the battery powder is adsorbed more thoroughly. Among them, the rotation speed of the spiral blade 222 matches the moving speed of the electromagnetic rod 33 on the conveyor belt 31, so that the electromagnetic rod 33 is inserted into the gap between the spiral blades 222 instead of directly abutting against the spiral blade, avoiding mutual interference. Another driving method is that the spiral blade 222 of the conveying mechanism 2 rotates to push the electromagnetic rod 33 towards the first discharge port 13, thereby driving the conveyor belt 31 to move.

[0043] In one embodiment, the end of the electromagnetic rod 33 abuts against the side surface of the spiral blade 222. When the rod body 221 of the screw 22 rotates, the spiral blade 222 rotates, and the side surface of the spiral blade 222 continuously generates a thrust on the end of the electromagnetic rod 33, causing the electromagnetic rod 33 and the conveyor belt 31 to move.

[0044] In one embodiment, there are two groups of electromagnetic rods 33, which are respectively arranged on both sides of the conveyor belt 31. Each group of electromagnetic rods 33 has a plurality of them and is evenly distributed. The lengths of the two groups of electromagnetic rods 33 are different, so that the depths inserted into the battery powder are different, which is conducive to fully adsorbing the iron powder in the battery powder.

[0045] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present application.
