The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated, that is, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In addition, unless otherwise specified, "multiple" means two or more.
[0034] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0035] As shown in Figures 1-7, an embodiment of the present application provides a battery powder iron removal magnetic separation device, which includes a body 1, a conveying mechanism 2, and a magnetic separation mechanism 3. The body 1 has a storage space 11 inside, a feed port 12 is provided at one end of the body 1, and a first discharge port 13 and a second discharge port 14 are provided at the other end of the body 1; the conveying mechanism 2 includes a motor 21 and a screw 22 driven by the motor 21, the screw 22 is arranged in the storage space 11, and the screw 22 is used to transport the battery powder from the feed port 12 to the first discharge port 13. In the process of the screw 22 transporting the battery powder, the iron powder in the battery powder is adsorbed by the electromagnetic rod 33, so that the non-magnetic material is discharged from the first discharge port; the magnetic separation mechanism 3 is arranged in the storage space 11 and is above the conveying mechanism 2. The magnetic separation mechanism 3 includes a conveyor belt 31, a conveying 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, and the first end area 31c and the second end area 31d are respectively arranged at the two 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 port 14; the conveying wheel 32 is used to maintain the smooth movement of the conveyor belt 31; one end of the electromagnetic rod 33 is installed on the surface of the conveyor belt 31, and the other end is in contact with the screw 22; the power rail 34 is installed on the inner wall of the body 1; wherein, the second horizontal area 31b is arranged opposite to the power 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 power rail 34, and the electromagnetic rod 33 is inserted into the battery powder conveyed by the conveying mechanism 2.
[0036] During operation, battery powder is fed through the feed port 12, and the conveying mechanism 2 is turned on to move the battery powder within the accommodation space of the body 1. The magnetic separation mechanism 3 is turned on, and the electromagnetic rod 33 on the conveyor belt 31 is driven to move by the conveying wheel 32. The electromagnetic rod 33 in the second horizontal area 31b and the energized guide rail 34 are energized to generate electromagnetic force. The electromagnetic rod 33 is inserted into the battery powder conveyed by the conveying mechanism 2 to absorb the iron powder therein. The battery powder with the adsorbed iron powder continues to move as the conveying mechanism 2 falls into the first discharge port 13. At the same time, the electromagnetic rod 33 is driven by the screw 22 to move along with the conveyor belt 31 into the second end area 31d. The electromagnetic rod 33 is disconnected from the energized guide rail 34 and loses the electromagnetic force, causing the iron powder to fall from the electromagnetic rod 33 and enter the second discharge port 14. It should be noted that the conveyor belt 31 moves in a circular motion 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.
[0037] Based on the above settings, the entire magnetic separation process does not require shutdown operations and can work continuously, making the magnetic separation efficiency high.
[0038] As shown in Figures 5 and 6, in one embodiment, the electromagnetic rod 33 includes a hollow rod 331, a coil 332 disposed within the rod 331, and a wire 333 connected to the coil 332. When the wire 33 is connected to a power source, the current flowing through the coil 332 generates an electromagnetic force, which enables the rod 331 to attract magnetic materials.
[0039] Specifically, the surface of the conveyor belt 31 is provided with a first conductive tape 311, which is electrically connected to the wire 333. The first conductive tape 311 includes two groups, which serve as the positive and negative electrodes and are electrically connected to the corresponding wire 333. A gap is provided between the two groups of first conductive tape 311 to achieve insulation and prevent short circuits.
[0040] Furthermore, a conductive groove 341 is provided on the side of the inner wall of the power rail 34 away from the body 1. A second conductive belt 342 is provided in the conductive groove 341, and the first conductive belt 311 abuts against the second conductive belt 342. The second conductive belt 342 includes two groups, which serve as the positive and negative poles and are electrically connected to the corresponding first conductive belt 311, and there is a gap between the two groups of second conductive belts 342 to achieve insulation and avoid short circuits. During actual operation, part of the structure of the conveyor belt 31 extends into the conductive groove 341. The contact surface between the first conductive belt 311 and the second conductive belt 342 is kept smooth, so that the conveyor belt 31 can also energize the electromagnetic rod 33 during movement.
[0041] As shown in FIG7 , in one embodiment, the energized guide rail 34 is provided with two sections, which are correspondingly provided on both sides of the second horizontal area 31 b , so as to facilitate the installation of as many electromagnetic rods 33 as possible and improve the efficiency of magnetic separation.
[0042] As shown in Figures 1-3, the conveying mechanism 2 also includes a stirring rod 23, which is fixed to the screw 22 along its axial direction. The provision of the stirring rod 23 allows the battery powder to be stirred and fully dispersed during the conveying process, which facilitates the insertion of the electromagnetic rod 33 into the battery powder and improves the efficiency of adsorbing iron powder.
[0043] Furthermore, the screw 22 includes a rod body 221 and a spiral blade 222 disposed on the rod body 221. An air inlet channel 223 is disposed within the rod body 221, and an air outlet 224 is disposed on the surface of the screw 221, which is connected to the air inlet channel 223. One end of the rod body 221 extends out of the body 1 and is connected to a positive pressure air source. During use, gas is introduced into the air inlet channel 223 of the rod body 221 and discharged from the air outlet 224, causing the battery powder to be blown up, which is more conducive to the iron powder therein being adsorbed by the electromagnetic rod 33, so that the iron powder in the battery powder is more thoroughly adsorbed. The rotation speed of the spiral blade 222 matches the movement 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 rather than directly abutting the spiral blades, thereby avoiding mutual interference. Another driving method is that the spiral blade 222 of the conveying mechanism 2 rotates, pushing the electromagnetic rod 33 toward the first discharge port 13, thereby driving the conveyor belt 31 to move.
[0044] In one embodiment, the end of the electromagnetic rod 33 abuts against the side of the spiral blade 222. When the rod body 221 of the screw 22 rotates, the spiral blade 222 rotates, and the side of the spiral blade 222 continuously generates thrust on the end of the electromagnetic rod 33, causing the electromagnetic rod 33 and the conveyor belt 31 to move.
[0045] In one embodiment, two sets of electromagnetic rods 33 are provided, one on each side of the conveyor belt 31. Each set of electromagnetic rods 33 includes multiple electromagnetic rods 33, which are evenly spaced. The two sets of electromagnetic rods 33 have different lengths, allowing them to be inserted into the battery powder at different depths, which facilitates sufficient adsorption of iron powder in the battery powder.
[0046] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present application. These improvements and replacements should also be regarded as the scope of protection of the present application.
