Description

Technical Field

[0001] This invention relates to the field of waste copper recycling technology, specifically to an environmentally friendly waste copper recycling and regeneration device. Background Technology

[0002] Copper is a red metal, but it is also a green metal. Scrap copper is a discarded item after use; simply throwing it away would be a waste of resources, so specialized recycling equipment is needed to recycle and reuse it.

[0003] The existing environmentally friendly recycling and reprocessing steps for waste copper are generally divided into primary crushing, vibration screening, air separation, magnetic separation, washing and drying, secondary crushing, and remelting. Since each step is placed separately, the material needs to be constantly transferred during the processing, which reduces the overall processing efficiency. However, in the above-mentioned magnetic separation process, it was found that the space area of ​​the feed inlet of the existing magnetic separation equipment is much larger than the conveying space area. As the initial channel for scrap copper to enter the magnetic separation process, the feed inlet's main function is to ensure that the material can smoothly enter the magnetic field area. However, in actual design, more attention is often paid to the smoothness of material conveying, while insufficient consideration is given to the distribution state of the material at the feed inlet. Due to the large space area of ​​the feed inlet, the material lacks effective constraint and guidance when entering. The material particles fall naturally under the action of gravity, which easily leads to accumulation. At the same time, the material itself has certain particle size differences and irregular shapes. The interaction of materials of different particle sizes and shapes during the flow process further aggravates the accumulation phenomenon. This mismatch between the feed rate and the material supply rate leads to material accumulation at the feed inlet. Furthermore, during subsequent transport, scrap copper accumulates on top of the magnetic material, hindering the magnetic field's adsorption. The magnetic field's adsorption capacity and area are limited; when magnetic material is covered by non-magnetic scrap copper, the magnetic field cannot effectively act on it, resulting in some magnetic material not being adsorbed and reducing the recovery rate. Secondly, the accumulated material affects the normal operation of the magnetic separator. Excessive material accumulation at the feed inlet can cause blockage, affecting normal material transport and further reducing the processing efficiency of the magnetic separator.

[0004] 2. Meanwhile, compared to existing technologies, some magnetic materials cannot accurately enter the discharge channel during use: The main factors affecting the magnetic material's performance are the material's properties and the equipment's operation. If the magnetic material has a large particle size difference, small particles are easily adsorbed onto larger particles. When the material is removed from the magnetic field, the larger particles fall rapidly due to gravity, while the smaller particles are obstructed by the larger particles and their own inertia, causing their trajectories to deviate and making it difficult for them to enter the channel. When the material contains a certain amount of moisture, the particles are prone to sticking together and forming agglomerates. After being removed from the magnetic field, these agglomerates will disperse unevenly and deviate from the expected path. In addition, from the perspective of equipment operation, if the cylinder rotates too fast, the material will gain a large tangential velocity and move away from the channel. If the rotation speed is too slow, the material will remain on the cylinder surface for a long time and be interfered with by subsequent adsorbed particles.

[0005] Some magnetic materials cannot accurately enter the discharge channel, which directly reduces the recovery rate of magnetic materials. Magnetic materials that deviate from the channel will mix into the waste copper, leading to an increase in the magnetic component content of the waste copper and causing resource waste. At the same time, this situation will affect the recycling of waste copper, and the waste copper containing magnetic impurities will be difficult to meet the standards for subsequent processing or utilization, increasing the cost of subsequent purification processes. In addition, if materials accumulate outside the channel, they may block other parts of the equipment, disrupt the normal operation rhythm, reduce the processing efficiency of the magnetic separator, and increase the frequency and difficulty of equipment maintenance.

[0006] On the other hand, after magnetic material particles are magnetized in a magnetic field, some retain weak magnetism due to the hysteresis effect. After leaving the magnetic field, they form residual magnetic chains, which cause the particles to attract each other and agglomerate, making it difficult for them to fall individually. Furthermore, if the material particles are irregular in shape or the outer wall of the cylinder has minor scratches or uneven surfaces after long-term use, the particles may become embedded in the gaps and form mechanical interlocking. In addition, if the humidity of the environment and the overall humidity of the material are high, a water film will form between the material and the cylinder wall. The surface tension of the water film increases the adhesion, making it impossible for the material to be thrown out in time.

[0007] However, some magnetic materials are adsorbed on the outer wall of the cylinder and cannot be ejected in time. As the amount of material adhering to the cylinder wall gradually increases over a long period of use, it will change the balance of the cylinder, leading to increased equipment vibration and increased motor load. This not only consumes more energy but may also shorten the service life of the motor and related components. At the same time, the surface of the adsorbed material will weaken the magnetic field's ability to attract newly entering materials, because the material itself may shield part of the magnetic field, which will reduce the subsequent adsorption effect of magnetic particles and further reduce the recovery rate of magnetic materials.

[0008] Therefore, in view of this, the present invention proposes an environmentally friendly recycling device for waste copper to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0009] To address the aforementioned technical problems, this invention provides an environmentally friendly waste copper recycling and regeneration device, thereby resolving the technical issues raised in the background section.

[0010] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a waste copper recycling and environmental protection regeneration device, comprising: a permanent magnet drum and an air separator disposed above the permanent magnet drum, wherein a screening machine, a screw feeder and a first crusher are sequentially disposed on one side of the air separator; A cleaning machine is provided below the permanent magnet drum, a dryer is provided below the discharge port of the cleaning machine, and a second crusher is provided at the discharge port of the dryer; A drive module is installed on the side of the permanent magnet drum. A material handling module is installed on the outside of the permanent magnet drum. An airflow assembly is provided above the permanent magnet drum. The airflow assembly includes an angled baffle and a flat baffle. The angled baffle and the flat baffle are symmetrically distributed. The end of the angled baffle near the material handling module is inclined and perpendicular to the material handling module. The end of the flat baffle near the material handling module is horizontal and parallel to the material handling module.

[0011] Furthermore, a drive spindle is installed inside the permanent magnet drum, and a neodymium iron boron permanent magnet is installed below the drive spindle. The material processing module is divided into a feeding port, a magnetic separation track, a waste copper discharge port, and a magnetic material discharge port according to the flow state. The feeding port is the material conveying area, the magnetic separation track is the magnetic separation area corresponding to the neodymium iron boron permanent magnet inside the permanent magnet drum, the waste copper discharge port is the area for discharging non-magnetic particles after magnetic separation, and the magnetic material discharge port is the area for discharging magnetic particles after magnetic separation.

[0012] Furthermore, the airflow assembly also includes a transmission component, which is composed of two upper and lower rotating wheels and a transmission belt. The lower rotating wheel of the transmission component is fixedly connected to the outer wall of the drive shaft in the permanent magnet drum, while the inner wall of the upper rotating wheel of the transmission component is fixedly connected to the main rotating shaft. The main rotating shaft and the drive shaft in the permanent magnet drum are connected through the transmission component. A protective shell is also installed on the outside of the transmission component, and the protective shell is fixedly connected to the permanent magnet drum.

[0013] Furthermore, a reciprocating screw shaft sleeve is uniformly fixedly connected to the outer wall of the main rotating shaft, and a nut sleeve plate is threadedly connected to the outer wall of the reciprocating screw shaft sleeve. The reciprocating screw shaft sleeve and the nut sleeve plate form a ball screw structure. A fixed circular plate is fixedly connected to the outer wall of the main rotating shaft at the end away from the nut sleeve plate. A connecting cylinder is fixedly connected to the outer wall of the fixed circular plate, and a piston structure is formed between every two adjacent nut sleeve plates and fixed circular plates and a local connecting cylinder.

[0014] Furthermore, the angled baffle is rotatably connected to the outside of the connecting cylinder near the feed port. A first connecting pipe is evenly installed inside the angled baffle. The first connecting pipe is in communication with the connecting cylinder. A one-way valve is installed inside the end of the first connecting pipe near the connecting cylinder, and an inclined exhaust hole is connected to the end of the first connecting pipe away from the connecting cylinder.

[0015] Furthermore, the tilt angle of the inclined exhaust hole is consistent with the tilt angle of the end of the first connecting pipe near the material handling module, and the overall diameter of the inclined exhaust hole is half the diameter of the first connecting pipe.

[0016] Furthermore, the flat-angle baffle is rotatably connected to the outside of the connecting cylinder near the magnetic material discharge port. A second connecting pipe is evenly installed inside the flat-angle baffle. The second connecting pipe is in communication with the connecting cylinder. A one-way valve is also installed inside the end of the second connecting pipe near the connecting cylinder. A vertical exhaust hole is connected to the end of the second connecting pipe away from the connecting cylinder.

[0017] Furthermore, the vertical exhaust port is vertically connected to the end of the second connecting pipe near the material handling module, and the overall diameter of the vertical exhaust port is twice the diameter of the second connecting pipe.

[0018] Furthermore, the permanent magnet roller is provided with a vibration assembly, which includes a limiting frame fixedly connected to the outer wall of the neodymium iron boron permanent magnet. A drive shaft is uniformly slidably connected inside the limiting frame. A return spring is sleeved on the outer wall of the drive shaft. A ball is fixedly connected to the side of the drive shaft near the drive spindle. A cam plate is uniformly fixedly connected to the outer wall of the drive spindle.

[0019] Furthermore, the two ends of the return spring are fixedly connected to the limiting frame and the ball respectively, and the ball is located on the rotation path of the corresponding cam plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are: (1) This device blows air quickly into the feed port area through the inclined exhaust hole. The high-speed airflow can directly act on the material accumulation area of ​​the feed port. The airflow impact force breaks up the agglomerated particles formed by particle size difference and irregular shape, and avoids non-magnetic waste copper covering magnetic materials. This directional blowing can effectively constrain and guide the material, so that the material remains loose and uniform before entering the magnetic separation track, so that the magnetic material is more fully exposed in the magnetic field, reducing the leakage of magnetic particles caused by accumulation, thereby improving the recovery rate of magnetic materials. At the same time, the airflow can also alleviate the problem of mismatch between the feed port conveying speed and the material supply speed, reduce the risk of blockage, ensure the continuity of material conveying, and improve the efficiency of waste copper recycling. During actual air blowing, the tilt angle of the inclined exhaust port is perpendicular to the feed inlet, which allows the high-speed airflow to act precisely and vertically on the material accumulation surface of the feed inlet. This angle design maximizes the effective utilization of the airflow impact force and avoids the airflow from diffusing to the side due to angle deviation, thus weakening the dispersing effect on the accumulated material. The vertical airflow can directly penetrate the material accumulation layer, breaking the mutual compression state of materials of different particle sizes and shapes, so that the material particles are fully dispersed before entering the magnetic separation track, ensuring that the magnetic material is not covered by non-magnetic waste copper and is more evenly exposed in the magnetic field.

[0021] (2) This device blows air slowly into the magnetic material discharge area through a vertical exhaust hole. The slow airflow gently acts on the magnetic material that has been removed from the magnetic field, which can break the adhesion between particles caused by residual magnetism or humidity. This prevents small magnetic particles from adhering to large particles and deviating from the collection path. Since the airflow speed is gentle, it will not interfere with the natural falling trajectory of the material, which can ensure that the magnetic material falls accurately into the magnetic material discharge port and reduce the loss caused by uneven particle dispersion. In addition, this blowing method can also avoid the disturbance caused by high-speed airflow to the magnetic material discharge area, ensuring the stability and accuracy of magnetic separation and classification.

[0022] In the actual blowing process, the vertical exhaust port is perpendicularly connected to one end of the magnetic material outlet, which allows the slow airflow to act precisely on the magnetic material that has been separated from the magnetic field in a vertically downward direction. This vertical blowing method avoids the impact force dispersion caused by the tilt of the airflow direction, and can also specifically break the adhesion between particles. Moreover, the vertical airflow will not interfere with the natural falling trajectory of the material, ensuring that the magnetic particles fall accurately into the magnetic material outlet. This not only ensures the effect of air blowing to assist dispersion, but also maintains the stability of the magnetic material collection area, further improving the accuracy and recovery rate of magnetic separation and classification.

[0023] The vertical exhaust port has a left-low and right-high design, with the lower end closer to the magnetic material discharge side. This creates an inclined airflow barrier, which prevents the high-speed material from affecting the airflow discharge path and gently blocks the overflowing particles, reducing their scattering. This guides the material to gather at the magnetic material discharge port, enhancing the protection and collection effect.

[0024] (3) This device installs the drive shaft in the critical area where the permanent magnet drum separates from the neodymium iron boron permanent magnet. Through its intermittent reciprocating vibration, it acts on the inner wall of the drum, which can accurately act on the magnetic material that has just lost its magnetic attraction. This design can effectively break the residual magnetic chains formed by the hysteresis effect between particles, resolve the problem of adhesion and agglomeration, and allow small particles to enter the magnetic material channel smoothly without being blocked by large particles. At the same time, the vibration force can overcome the surface tension of the water film between the material and the drum wall, shake off the particles embedded in the scratches on the drum wall, and avoid the residue caused by mechanical embedding. At the same time, the vibration can also adapt to the material movement state at different speeds, reducing the impact of inertia. The deviation in trajectory caused by excessive deviation or prolonged residence reduces the magnetic component content in the waste copper. In addition, the concentrated vibration force acts on the critical position of material separation, which can promptly clean the material adhering to the drum wall, preventing it from accumulating for a long time and changing the balance of the drum. This reduces equipment vibration and motor load, lowers energy consumption, and extends the service life of components. At the same time, it avoids residual material shielding the magnetic field, ensuring the adsorption effect of subsequent magnetic particles and maintaining stable magnetic separation efficiency. Moreover, this targeted design does not require an additional power source, has high synchronization with the drum operation, solves the recycling problem without interfering with the normal operation of the magnetic field, and balances separation effect and equipment stability.

[0027] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention. It should be noted that the structure and working principle of the aforementioned permanent magnet roller 1, drive module 11, material handling module 12, and other components are existing technologies and will not be described in detail here.

[0028] Example 1 Please refer to Figure 1 - Figure 11 As shown, an environmentally friendly waste copper recycling device includes: a permanent magnet drum 1 and an air separator 4 disposed above the permanent magnet drum 1. A screening machine 5, a screw feeder 6, and a first crusher 7 are sequentially arranged on one side of the air separator 4; a washing machine 10 disposed below the permanent magnet drum 1, a dryer 9 disposed below the discharge port of the washing machine 10, and a second crusher 8 disposed at the discharge port of the dryer 9; and a drive module 11 installed on the side of the permanent magnet drum 1. Material is mounted on the outside of the permanent magnet drum 1. The processing module 12 has an airflow assembly 2 above the permanent magnet roller 1. The airflow assembly 2 includes an angled baffle 28 and a flat baffle 211. The angled baffle 28 and the flat baffle 211 are symmetrically distributed. The end of the angled baffle 28 near the material processing module 12 is designed to be inclined and is perpendicular to the material processing module 12. The end of the flat baffle 211 near the material processing module 12 is horizontal and is parallel to the material processing module 12. The discharge port of the first crusher 7 is connected to the inlet of the screw feeder 6 via a pipe. The discharge port of the screw feeder 6 is located above the screening machine 5. The discharge port of the small particles screened out by the screening machine 5 is connected to the inlet of the air separator 4 via a pipe. The large particles of material from the screening machine 5 can be conveyed to the first crusher 7 for re-crushing via an external conveying device. The discharge port of the air separator 4 is connected to the inlet of the permanent magnet drum 1 via a pipe, so that the material discharged by the air separator 4 enters the permanent magnet drum 1 for magnetic separation. The magnetically separated waste copper is discharged into the washing machine. The waste copper is washed in the first mill 10, and then tilted and conveyed to the dryer 9 for drying. The dried waste copper enters the second crusher 8 for fine crushing, and finally is conveyed to the furnace for recycling through other conveying devices (since it is existing technology, it is not described in detail in this solution). This realizes the recycling of waste copper. By integrating the permanent magnet drum 1, air classifier 4, screening machine 5, screw feeder 6, first crusher 7, washing machine 10, dryer 9 and second crusher 8 into one process, the efficiency of waste copper recycling is improved. It should be noted that the permanent magnet drum 1 is equipped with a drive spindle, and a neodymium iron boron permanent magnet is installed below the drive spindle. The material processing module 12 is divided into a feeding port 121, a magnetic separation track 122, a waste copper discharge port 123, and a magnetic material discharge port 124 according to the flow state. The feeding port 121 is the material conveying area. The magnetic separation track 122 is the magnetic separation area corresponding to the neodymium iron boron permanent magnet inside the permanent magnet drum 1. The waste copper discharge port 123 is the area for discharging non-magnetic particles after magnetic separation. The magnetic material discharge port 124 is the area for discharging magnetic particles after magnetic separation.

[0029] Please refer to Figure 1 - Figure 11As shown, the airflow assembly 2 also includes a transmission component 21. The transmission component 21 is composed of two upper and lower rotating wheels and a transmission belt. The lower rotating wheel of the transmission component 21 is fixedly connected to the outer wall of the drive shaft in the permanent magnet drum 1, while the inner wall of the upper rotating wheel of the transmission component 21 is fixedly connected to the main rotating shaft 22. The main rotating shaft 22 and the drive shaft in the permanent magnet drum 1 are connected through the transmission component 21. A protective shell 2101 is also installed on the outside of the transmission component 21. The protective shell 2101 is fixedly connected to the permanent magnet drum 1. Reciprocating wires are uniformly fixedly connected to the outer wall of the main rotating shaft 22. The reciprocating screw bushing 23 has a nut sleeve plate 24 threadedly connected to its outer wall. The reciprocating screw bushing 23 and the nut sleeve plate 24 form a ball screw structure. A fixed circular plate 25 is fixedly connected to the outer wall of the main rotating shaft 22 at the end away from the nut sleeve plate 24. A connecting cylinder 26 is fixedly connected to the outer wall of the fixed circular plate 25. Each pair of adjacent nut sleeve plates 24 and fixed circular plates 25 forms a piston structure with a local connecting cylinder 26. An angled baffle 28 is rotatably connected to the outside of the connecting cylinder 26 near the feed port 121. The interior of the angled baffle 28 is uniformly... A first connecting pipe 27 is installed, which is connected to the connecting cylinder 26. A one-way valve 213 is installed inside the end of the first connecting pipe 27 near the connecting cylinder 26, and an inclined vent 29 is connected to the end of the first connecting pipe 27 away from the connecting cylinder 26. The inclination angle of the inclined vent 29 is consistent with the inclination angle of the end of the first connecting pipe 27 near the material handling module 12, and the overall diameter of the inclined vent 29 is half the diameter of the first connecting pipe 27. A flat-angle baffle 211 is rotatably connected to the outside of the connecting cylinder 26 near the magnetic field. On one side of the material discharge port 124, a second connecting pipe 210 is evenly installed inside the flat angle baffle 211. The second connecting pipe 210 is connected to the connecting cylinder 26, and a one-way valve 213 is also installed inside the end of the second connecting pipe 210 near the connecting cylinder 26. A vertical exhaust hole 212 is connected to the end of the second connecting pipe 210 away from the connecting cylinder 26. The vertical exhaust hole 212 is vertically connected to the end of the second connecting pipe 210 near the material processing module 12, and the overall diameter of the vertical exhaust hole 212 is twice the diameter of the second connecting pipe 210.

[0030] Specifically, such as Figure 3 As shown, the material enters the device from the feed port 121 and falls into the magnetic separation track 122. The permanent magnet drum 1 rotates under the drive module 11. The neodymium iron boron permanent magnet inside forms a fixed magnetic field. The magnetic material is attracted to the surface of the drum and rotates with it, while the non-magnetic particles fall directly along the magnetic separation track 122 and are discharged from the waste copper outlet 123. When the magnetic material rotates with the drum to the area where it leaves the magnetic field and corresponds to the position of the magnetic material outlet 124, it loses the magnetic attraction and falls into the magnetic material outlet 124, thus completing the magnetic separation and grading.

[0031] The first connecting pipe 27 rapidly blows air into the feed inlet 121 area through the inclined exhaust hole 29: The power source for the airflow assembly 2 is the drive spindle inside the permanent magnet drum 1. The drive spindle, through the upper and lower rotating wheels and the transmission belt in the transmission component 21, drives the main rotating shaft 22 to rotate synchronously. The reciprocating screw sleeve 23 on the main rotating shaft 22 rotates accordingly. Since the reciprocating screw sleeve 23 and the nut sleeve 24 form a ball screw structure, the nut sleeve 24 reciprocates axially along the screw sleeve. Because each pair of adjacent nut sleeves 24 and the fixed circular plate 25 forms a piston structure with a local connecting cylinder 26, when the nut sleeve 24 approaches the fixed circular plate 25, the internal space of the connecting cylinder 26 between them is... Compression occurs when the one-way valve 213 opens, and gas is quickly pushed through the first connecting pipe 27 to the inclined exhaust port 29. Since the diameter of the inclined exhaust port 29 is only half that of the first connecting pipe 27, the gas velocity is amplified, forming a high-speed airflow. The inclined end of the angled baffle 28 is perpendicular to the feed port 121, and the angle of the inclined exhaust port 29 matches it. The high-speed airflow is precisely blown towards the material accumulation area of ​​the feed port 121, breaking up the agglomeration of particles and preventing non-magnetic waste copper from covering magnetic materials. When the nut sleeve 24 moves away from the fixed circular plate 25, the connecting cylinder 26 draws in air, and the one-way valve 213 closes, storing energy for the next air blowing.

[0032] The second connecting pipe 210 slowly blows air into the magnetic material discharge port 124 area through the vertical exhaust hole 212: Similarly, driven by the rotation of the main shaft 22, the reciprocating motion of the nut sleeve 24 also acts on the inside of the connecting cylinder 26. When the internal space of the connecting cylinder 26 is compressed, the one-way valve 213 inside the second connecting pipe 210 is also in the open state. The gas is sent to the vertical exhaust hole 212 through the second connecting pipe 210. Since the diameter of the vertical exhaust hole 212 is twice that of the second connecting pipe 210, the gas flow rate is reduced, forming a slow airflow. The horizontal end of the flat angle baffle 211 is parallel to the magnetic material discharge port 124. The vertical exhaust hole 212 blows air vertically downward, gently acting on the magnetic material that has been separated from the magnetic field. On the one hand, it helps to disperse the adhering particles and ensures that they fall accurately into the magnetic material discharge port 124. On the other hand, it avoids the high-speed airflow from interfering with the falling trajectory of the material. Throughout the process, the angled baffle 28 and the flat angle baffle 211 always maintain the blowing direction and accurately correspond to the material area, while the protective shell 2101 protects the transmission component 21 from dust interference.

[0033] Based on Example 1, please refer to Figure 1 - Figure 11As shown, a vibration assembly 3 is provided inside the permanent magnet roller 1. The vibration assembly 3 includes a limiting frame 31 fixedly connected to the outer wall of the neodymium iron boron permanent magnet. A drive shaft 32 is uniformly slidably connected inside the limiting frame 31. A return spring 33 is sleeved on the outer wall of the drive shaft 32. A ball bearing 34 is fixedly connected to the side of the drive shaft 32 near the drive spindle. A cam plate 35 is uniformly fixedly connected to the outer wall of the drive spindle. The two ends of the return spring 33 are fixedly connected to the limiting frame 31 and the ball bearing 34, respectively. The ball bearing 34 is located on the rotation path of the corresponding cam plate 35.

[0034] Specifically, when the permanent magnet drum 1 is running, the drive module 11 drives the internal drive spindle to rotate. The spindle simultaneously drives the permanent magnet drum 1 to rotate and the cam plate 35 to rotate synchronously. The limiting frame 31 of the vibration component 3 is fixed on the outer wall of the neodymium iron boron permanent magnet. The drive shaft 32 inside it can slide axially along the frame. The reset spring 33 always applies a pulling force to the drive shaft 32 in the direction of the drive spindle, so that the ball 34 at the end of the shaft is in close contact with the rotation path of the cam plate 35. When the drive spindle rotates the cam plate 35, the protruding part of the cam plate 35 periodically contacts and squeezes the ball 34, pushing the drive vibration shaft 32 to slide away from the spindle. At this time, the return spring 33 is stretched and stores force. After the protruding part of the cam plate 35 passes the ball 34, the return spring 33 releases its elasticity, pulling the drive vibration shaft 32 to rebound quickly. The ball 34 re-adheres to the smooth surface of the cam plate 35. This process causes the drive vibration shaft 32 to reciprocate linearly along the limiting frame 31, generating intermittent mechanical vibration force. Since the limiting frame 31 is fixed to the outer wall of the neodymium iron boron permanent magnet, and the installation position of the vibration component 3 corresponds to the permanent magnet roller 1 and... The area where the neodymium iron boron permanent magnet detaches, i.e. the critical position where the magnetic material loses its magnetic attraction, is where the reciprocating vibration of the drive shaft 32 is transmitted to the inner wall of the permanent magnet drum through the limiting frame 31. The vibration force is transmitted to the externally attached magnetic material through the drum wall, breaking the residual magnetic chain adhesion and surface tension between particles, while overcoming the mechanical interlocking resistance, forcing the residual material to detach from the drum surface, ensuring that it falls accurately into the magnetic material discharge port 124. Throughout the process, the vibration component 3 achieves intermittent vibration through a purely mechanical structure, without the need for an additional power source. It has high synchronization with the operation of the permanent magnet drum 1 and can accurately act on the key area where the material detaches, effectively improving the detachment efficiency of the magnetic material.
