Description
Technical Field
[0001] The utility model relates to the technical field of eddy current separation, in particular to a novel eddy current separation machine. Background Art
[0002] The working principle of the eddy current separator is that when the permanent magnet rotates at high speed, a high-speed changing magnetic field will be formed. When a metal with good conductivity passes through the magnetic field, an eddy current will be generated on the metal surface. The magnetic field generated by the eddy current is opposite to the background magnetic field, so that the metal particles will generate a repulsive force. This repulsive force will change the movement trajectory of the metal particles. Because non-metallic particles will not produce electromagnetic induction effect, when the mixed particle group formed by metal particles and non-metallic particles passes through the alternating magnetic field, due to different forces, the trajectories formed by the metal particles and non-metallic particles are different, thereby realizing the separation of metal particles and non-metallic particles.
[0003] Existing invention patents such as CN110152854B, "Aluminum Electrolytic Capacitor Waste Recycling Method and Recycling Device" use conveyor belts to transport materials. Their structure is relatively complex and will cause a problem. After the conveyor belt transports the materials to be sorted to the sorting area, two or more layers of materials may be formed in the sorting area, which will produce two adverse effects. First, when the inner metal material moves outward due to the repulsive force of the magnetic field, it will collide with the outer particles, making it impossible to change the motion trajectory to complete the sorting; second, the metal particles in the outer layer are far away from the magnetic roller, and their own induced magnetic field is small. The repulsive force formed between the two magnetic fields is not enough to push the metal particles to change their motion trajectory, so the sorting work cannot be completed. And it has been disclosed. Utility Model Content

[0026] The adjusting part includes a connecting rod 18, which is movably arranged on the inner wall surface of the box body 16, and the connecting rod 18 passes through the rear plate 302.

[0029] Specific, combined Figure 2 Explain its working principle: a magnetic field that changes with time can induce an electric field, and this phenomenon is called the law of electromagnetic induction; a conductor with current can excite a magnetic field, and this phenomenon is called the Biot-Savart law.
[0030] like Figure 2As shown, mixed particles containing non-magnetic conductive metal 10 (such as lead, copper, zinc and other materials) and non-metallic particles 11 are injected into the trough of the vibrating feeder 2. All particles rely on vibration and gravity to make the mixed particles fully loose in the trough to form a single layer of material, and the mixed particles are transported to the sliding inclined slide 3. The non-metallic particles 11 in the mixed particles continue to accelerate along the path L2 to make parabolic motion under the action of gravity G and vibration impact force, and finally fall into the non-metallic collection trough 6 after being blocked by the dividing plate 5. The eddy current magnetic roller 4 rotates at a certain speed to form an alternating magnetic field near the sliding inclined slide 3. When the mixed particles pass through the alternating magnetic field at a certain speed, induced eddy currents will be generated in the metal particles 10. The induced eddy current will generate a magnetic field with an opposite magnetic pole to the alternating magnetic field. Since the particle flow and the magnetic field have a relative motion speed, there is a repulsive force F on the metal particles 10 that generate the eddy current. r This repulsive force and the gravity G on the particles themselves will combine to form a resultant force F. Under the action of the resultant force F, the metal particles will be accelerated and thrown in the direction of the resultant force and move along the path L2, thereby changing the trajectory of the metal particles. After being blocked by the dividing plate 5, they fall into the non-ferrous metal collection tank. Due to the action of the alternating magnetic field, some non-ferrous metals can be separated from the mixed material flow.
[0031] The existing sorting technology uses a conveyor belt to transport the materials to be sorted to the sorting area, which may form two or more layers of materials in the sorting area, which will cause two adverse effects. First, the inner metal material will collide with the outer particles when it moves outward due to the repulsive force of the magnetic field, making it impossible to change the motion trajectory and complete the sorting; second, the metal particles in the outer layer are far away from the magnetic roller, and their own induced magnetic field is small. The repulsive force formed between the two magnetic fields is not enough to push the metal particles to change their motion trajectory, so the sorting work cannot be completed.
