Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field related to commercial ceiling fans with permanent magnet synchronous motors, and more specifically, relates to an eccentric eddy current separator based on a separation and control mechanism. Background Art
[0002] The operating principle of an eccentric eddy current separator is based on the phenomenon of induced currents (eddy currents) generated by a conductor in a high-frequency alternating magnetic field. When a conductive non-ferrous metal block passes through the magnetic field generated by a high-speed rotating magnetic roller, an eddy current magnetic field is generated within the non-ferrous metal. The direction of this eddy current magnetic field is opposite to the original magnetic field, generating a mutually repulsive force that ejects the non-ferrous metal along its conveying direction, separating it from non-metallic materials such as glass and plastic. However, existing commercial ceiling fans with permanent magnet synchronous motors have the following drawbacks: In the prior art, after the eccentric eddy current separator is manufactured, the position of the magnetic roller relative to the outer cylinder is fixed. During the sorting process, due to the different sizes of different types of materials, there will be certain differences in the sorting effect, resulting in poor sorting effect of the eccentric eddy current separator.
[0003] In the existing technology, the position between the magnetic roller and the belt in the eccentric eddy current separator is fixed and cannot be adjusted. When the magnetic roller inside the sorting drum rotates at high speed, the sorting drum becomes relatively heavy. Therefore, the starting position when sorting non-ferrous metals cannot be adjusted and is concentrated above the sorting drum. The sorting position is single, which seriously affects the utilization rate of the magnetic roller.
[0004] In the existing technology, the belt in the eddy current separator is usually in a horizontal state. During the sorting process, due to the different sizes of different types of materials, it cannot adapt to the sorting of materials with different particle size ranges; there is an angle between the belt and the horizontal axis direction. The angle can change the parabolic trajectory of non-metallic materials, making the parabolic angle between non-metallic and non-ferrous metals larger, the parabolic route clearer, and the ratio of sorting non-ferrous metals higher.
[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an eccentric eddy current separator based on a sorting control mechanism is provided, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses an eccentric eddy current separator based on a sorting and control mechanism. The separator comprises a first movable frame, a sliding rod, a collar, a second movable frame, and a roller. Two electrically operated telescopic rods extend from the separator to drive the two sliders upward. The upward movement of the two sliders drives the two first movable frames, the sliding rod, and the collar upward. The upward movement of the two sliding rods and collar drives the second movable frame, the rollers, and the magnetic roller upward. The upward movement of the magnetic roller reduces the gap between the magnetic roller and the conveyor belt, thereby maximizing the utilization of the magnetic roller. The starting position for non-ferrous metal separation can be effectively selected based on the size, thickness, and weight of the material, thereby diversifying the non-ferrous metal separation positions. Furthermore, the upward movement of the second movable frame and the roller creates an angle between the conveyor belt and the horizontal axis. The angle is adjusted based on the distance the rollers move upward. This angle can alter the parabolic trajectory of the non-metallic material, increasing the parabolic angle between the non-metallic and non-ferrous metals, resulting in a clearer parabolic path and a higher ratio of non-ferrous metal separation. This improves the eddy current separation efficiency of heavier materials.
[0018] The present invention discloses an eccentric eddy current separator based on a sorting and regulating mechanism. The elliptical plate, the slide plate, the second spring, the push plate, the slot, and the second slider are arranged. Under the rotational guidance of the elliptical plate and the elastic force of the second spring, the second slider is made to reciprocate horizontally in the horizontal chute. The reciprocating motion of the two second sliders drives the magnetic roller to reciprocate horizontally. The reciprocating motion of the magnetic roller can expand the effective action area of the magnetic roller, and the reciprocating motion of the magnetic roller matches the speed of the conveyor belt, prolonging the residence time of the conductive particles in the strong magnetic field area, so that they are fully affected by the eddy current force and reducing leakage. Then, through the arrangement of the protrusion, under the guidance of the protrusion and the gravity of the first slider and the roller, the first slider and the roller are made to move up and down in a small range. The roller shakes up and down, causing the material on the surface of the conveyor belt to shake and break up the material accumulation, so that the material is more evenly distributed on the surface of the conveyor belt, reducing the eddy current shielding effect caused by local excessive thickness. Finally, through the arrangement of the push rod, piston plate, first spring, hydraulic chamber, connecting channel, air bag, rotating plate and rubber block, the upper side of the roller is supported by the conveyor belt, and the roller and the first slider are fixed and the first movable block moves upward, so that the elastic member supports the push rod and the piston plate and makes the piston plate slide in the hydraulic chamber, and the gas in the hydraulic chamber enters the two air bags through the two connecting channels respectively. The expansion of the two air bags pushes the two rotating plates to rotate, and the rotation of the two rotating plates drives the two rubber blocks to approach each other. The two rubber blocks approach each other to squeeze and frictionally limit the two sides of the elastic member, which is beneficial to improve the buffering effect of the first movable block on the elastic member and reduce the range of movement of the first slider and the roller in the second movable frame, which is beneficial to make the first slider and the first movable block move up and down slightly in the second movable frame to produce a shaking effect while reducing the angle between the conveyor belt and the horizontal axis.

[0035] Preferably, refer to the attached Figure 9 An electric telescopic rod 30 is installed at the lower end of the first fixed frame 28 , and the extended end of the electric telescopic rod 30 is fixedly connected to the lower side of the slider 29 .
[0036] Preferably, refer to the attached Figure 7 , Attachment Figure 11 The center of the magnetic roller 18 is eccentric to the center of the driven roller 16, and the magnetic roller 18 can generate a magnetic field.
[0037] Specific use of the present invention: The staff conveys the material to the vibrating feeder 12, which starts to vibrate and disperse the material evenly and conveys the material to the conveyor belt 17. The control system controls the drive motor 19 to start, which drives the drive roller 15 to rotate. The rotation of the drive roller 15 drives the conveyor belt 17 to move, and the movement of the conveyor belt 17 drives the material to move closer to the magnetic roller 18. The control system controls the first stepper motor 20 to start, which drives the magnetic roller 18 to rotate at high speed. The magnetic poles NS of the magnetic roller 18 are arranged alternately. When rotating at high speed, an alternating magnetic field is generated. There is a gap and no contact between the magnetic roller 18 and the conveyor belt 17. When the material is conveyed from the conveyor belt 17 to the oblique upper part of the magnetic roller 18, an induced eddy current is generated. Non-ferrous metals such as copper and aluminum are repelled by the repulsive force and are bounced to the outside of the separator plate 22. Non-ferrous metal materials are not repelled and fall between the conveyor belt 17 and the separator plate 22, thereby finally sorting out the non-ferrous metals such as copper and aluminum.
[0038] When the material is heavy, the material's jump height is limited due to its large weight, making separation difficult. Therefore, the position of the magnetic roller 18 needs to be adjusted. The two electric telescopic rods 30 in the sorting control mechanism extend to drive the two sliders 29 upward. The upward movement of the two sliders 29 drives the two first movable frames 25, the slide bars 26, and the collar 27 upward. The upward movement of the two slide bars 26 and collar 27 drives the second movable frame 23, the roller 24, and the magnetic roller 18 upward. The upward movement of the magnetic roller 18 narrows the gap between the magnetic roller 18 and the conveyor belt 17, thereby maximizing the utilization of the magnetic roller 18. The jump position for non-ferrous metal separation can be effectively selected based on the size, thickness, and weight of the material, diversifying the separation positions for non-ferrous metals. Then, by moving the second movable frame 23 and the roller 24 upward, an angle is formed between the conveyor belt 17 and the horizontal axis direction. The angle is adjusted according to the distance the roller 24 moves upward. The angle can change the parabolic trajectory of the non-metallic material, making the parabolic angle between the non-metallic and non-ferrous metals larger, the parabolic route clearer, the ratio of sorting non-ferrous metals higher, and the effect of eddy current sorting of heavier materials. Among them, the two sliders 29 slide vertically in the two first fixed frames 28 respectively, so that the magnetic roller 18 and the second movable frame 23 move up and down smoothly. The up and down movement of the magnetic roller 18 drives the two second sliders 50 to move up and down in the two vertical chutes 48 respectively, so that the magnetic roller 18 moves up and down smoothly. And the up and down movement of the ring 27 drives the mounting plate 56 and the first stepper motor 20 to move up and down, so that the output end of the first stepper motor 20 and the second slider 50 move up and down at the same time.
[0039] Simultaneously, the upward movement of the second movable frame 23 drives the two pairs of second movable blocks 43 upward. As one end of the second movable block 43 contacts the inclined surface of a guide block 45, the second movable blocks 43 move upward, guided by the inclined surface of the guide block 45, thereby pushing the second movable blocks 43 to slide horizontally within the second movable frame 23. As the other end of the second movable block 43 slides in contact with the inclined surface of one end of the third movable block 44, the second movable block 43 guides the third movable block 44 while sliding. As a result, the two pairs of second movable blocks 43 guide the two third movable blocks 44 toward each other. As one side of the third movable block 44 slides in contact with the inclined surface of one side of the first movable block 34, the two third movable blocks 44 approach each other, guiding the first movable block 34, thereby moving the first movable block 34 upward. The upward movement of the first movable block 34 compresses the elastic member 33, thereby increasing the elastic force generated by the compression of the elastic member 33 and improving the cushioning effect on the roller 24 and the first slider 32.
[0040] Then, the upper side of the roller 24 is pressed by the conveyor belt 17, and the roller 24 and the first slider 32 are fixed and cooperate with the first movable block 34 to move upward, so that the elastic member 33 presses against the push rod 38 and the piston plate 36, so that the piston plate 36 slides in the hydraulic chamber 35, and the gas in the hydraulic chamber 35 enters the two air bags 40 through the two connecting channels 41. The two air bags 40 expand and push the two rotating plates 39 to rotate. The rotation of the two rotating plates 39 drives the two rubber blocks 42 to approach each other. The two rubber blocks 42 approach each other to squeeze and frictionally limit the two sides of the elastic member 33, which is beneficial to improve the buffering effect of the first movable block 34 on the elastic member 33 and reduce the range of movement of the first slider 32 and the roller 24 in the second movable frame 23. It is beneficial to make the first slider 32 and the first movable block 34 move up and down in a small range in the second movable frame 23 to produce a shaking effect while reducing the impact on the angle between the conveyor belt 17 and the horizontal axis direction. The piston plate 36 slides in the hydraulic chamber 35 to compress the first spring 37 to generate elastic force, and the elastic force generated by the first spring 37 is used to move and reset the piston plate 36.
[0041] The control system then activates the two second stepper motors 21. The second stepper motors 21 rotate, driving the elliptical plate 51. The outer wall of the elliptical plate 51 makes sliding contact with one side of the slide plate 52. As the longer side of the elliptical plate 51 presses against the slide plate 52, the slide plate 52 drives the push plates 53 toward the second slider 50. The push plates 53 move, using the retaining grooves 54 to position the second slider 50, causing the second slider 50 to move horizontally into the horizontal chute 49. The movement of the second slider 50 pushes the movable plate 57, which compresses the second spring 55 and generates a spring force. When the shorter side of the elliptical plate 51 contacts the slide plate 52, the spring force of the second spring 55 pushes the movable plate 57 back to its original position. This movement pushes the second slider 50 into the vertical chute 48. Under the guidance of the elliptical plate 51 and the spring force of the second spring 55, the second slider 50 undergoes horizontal reciprocating motion within the horizontal chute 49. The reciprocating motion of the two second sliders 50 drives the magnetic roller 18 to reciprocate in the horizontal direction. The reciprocating motion of the magnetic roller 18 can expand the effective action area of the magnetic roller 18, and the reciprocating motion of the magnetic roller 18 matches the speed of the conveyor belt 17, thereby extending the residence time of the conductive particles in the strong magnetic field area, allowing them to be fully affected by the eddy current force and reducing leakage.
[0042] Finally, the reciprocating motion of the magnetic roller 18 drives the two rings 27 to reciprocate horizontally. This reciprocating motion of the two rings 27 drives the two slide bars 26 to reciprocate horizontally, which in turn drives the second movable frame 23 to reciprocate horizontally. The reciprocating motion of the second movable frame 23 drives the two pairs of second movable blocks 43 to reciprocate horizontally. With one end of each second movable block 43 slidingly contacting the outside of a protrusion 46, the second movable blocks 43, guided by the protrusion 46, slide slightly horizontally within the second movable frame 23. With the other end of each second movable block 43 slidingly contacting the inclined surface of one end of a third movable block 44, the second movable block 43 guides the third movable block 44. This guidance of the two pairs of second movable blocks 43 brings the two third movable blocks 44 closer together. With one side of each third movable block 44 slidingly contacting the inclined surface of one side of the first movable block 34, the two third movable blocks 44 move closer together, guiding the first movable block 34 and causing it to move slightly upward. The first movable block 34 moves slightly upward, causing the elastic member 33, first slider 32, and roller 24 to move slightly upward. Then, when one end of the second movable block 43 disengages from the exterior of the protrusion 46, the weight of the first slider 32 and roller 24 causes them to move downward. Guided by the protrusion 46 and the weight of the first slider 32 and roller 24, the first slider 32 and roller 24 move slightly up and down. The up and down vibration of the roller 24 shakes the material on the surface of the conveyor belt 17, breaking up any accumulation and distributing it more evenly across the surface. This reduces the eddy current shielding effect caused by excessive thickness in certain areas.
[0043] The present invention relates to an eccentric eddy current separator based on a sorting and control mechanism. By configuring a first movable frame 25, a slide bar 26, a collar 27, a second movable frame 23, and a roller 24, two electric telescopic rods 30 in the sorting and control mechanism extend to drive two sliders 29 to move upward. The upward movement of the two sliders 29 drives the two first movable frames 25, the slide bar 26, and the collar 27 to move upward. The upward movement of the two slide bars 26 and the collar 27 drives the second movable frame 23, the roller 24, and the magnetic roller 18 to move upward. The upward movement of the magnetic roller 18 reduces the gap between the magnetic roller 18 and the conveyor belt 17, thereby maximizing the utilization of the magnetic roller 18. The take-off position for non-ferrous metal separation can be effectively selected based on the size, thickness, and weight of the material, thereby diversifying the separation positions for non-ferrous metals. Then, the second movable frame 23 and the roller 24 are moved upward to form an angle between the conveyor belt 17 and the horizontal axis direction. The angle is adjusted according to the distance that the roller 24 moves upward. The angle can change the parabolic trajectory of the non-metallic material, making the parabolic angle between the non-metal and the non-ferrous metal larger, the parabolic route clear, the ratio of sorting non-ferrous metals higher, and the effect of eddy current sorting of heavier materials.
[0044] The present invention employs an eccentric eddy current separator based on a separation control mechanism. The separator comprises an elliptical plate 51, a slide plate 52, a second spring 55, a push plate 53, a slot 54, and a second slider 50. Under the rotational guidance of the elliptical plate 51 and the elastic force of the second spring 55, the second slider 50 is caused to reciprocate horizontally within the horizontal chute 49. The reciprocating motion of the two second sliders 50 drives the magnetic roller 18 to reciprocate horizontally. This reciprocating motion expands the effective area of action of the magnetic roller 18, and the reciprocating motion of the magnetic roller 18 matches the speed of the conveyor belt 17, extending the residence time of the conductive particles in the strong magnetic field, allowing them to be fully affected by the eddy current force and reducing missed separations. Then, through the setting of the protrusion 46, under the guidance of the protrusion 46 and the gravity of the first slider 32 and the roller 24, the first slider 32 and the roller 24 move up and down slightly, and the roller 24 shakes up and down, causing the material on the surface of the conveyor belt 17 to shake and break up the material accumulation, so that the material is more evenly distributed on the surface of the conveyor belt 17, reducing the eddy current shielding effect caused by local excessive thickness. Finally, through the setting of the push rod 38, piston plate 36, first spring 37, hydraulic chamber 35, connecting channel 41, airbag 40, rotating plate 39, and rubber block 42, the upper side of the roller 24 is supported by the conveyor belt 17. The roller 24 and the first slider 32 are fixed and cooperate with the first movable block 34 to move upward, so that the elastic member 33 presses against the push rod 38 and the piston plate 36, causing the piston plate 36 to slide in the hydraulic chamber 35, and the gas in the hydraulic chamber 35 enters the two airbags 40 through the two connecting channels 41 respectively. The two airbags 40 expand and push The two rotating plates 39 are rotated, and the rotation of the two rotating plates 39 drives the two rubber blocks 42 to approach each other. The two rubber blocks 42 approach each other to squeeze and frictionally limit the two sides of the elastic member 33, which is beneficial to improving the buffering effect of the first movable block 34 on the elastic member 33, and reducing the range of movement of the first slider 32 and the roller 24 in the second movable frame 23. It is beneficial to make the first slider 32 and the first movable block 34 move up and down in a small range in the second movable frame 23 to produce a shaking effect, while reducing the impact on the angle between the conveyor belt 17 and the horizontal axis direction.
