Abstract
Description
Technical Field
[0001] The invention belongs to the field of material transmission and sorting, and in particular relates to a material dispersing and throwing integrated conveying and sorting equipment based on eddy current sorting. Background Art
[0002] Eddy current separation is a separation technology that utilizes the difference in electrical conductivity of materials. Its basic principle is based on two key physical phenomena: one is that an alternating magnetic field that changes with time will be accompanied by an alternating electric field (law of electromagnetic induction); the other is that a current-carrying conductor will generate a magnetic field in a magnetic field (Biot-Savart law), that is, when working, a high-frequency alternating strong magnetic field is generated on the surface of the separation magnetic roller (a high-frequency alternating strong magnetic field is a magnetic field with a large magnetic field intensity and a high-frequency periodic change in the direction of the magnetic field over time, wherein a higher current frequency helps to generate high-frequency magnetic field changes; a larger current can enhance the magnetic field intensity; and the number of turns and shape of the coil will affect the distribution and intensity of the magnetic field). When conductive non-ferrous metals pass through the magnetic field, eddy currents are induced inside them. This eddy current will generate a magnetic field in the opposite direction of the original magnetic field, causing the non-ferrous metals to leap forward along the conveying direction due to the repulsive force of the magnetic field, and then the metal materials and non-metallic materials are separated by the partitions arranged in the separation area.
[0003] However, the sorting efficiency of eddy current separation is affected by many factors, such as the amount of non-ferrous metals in the solid waste crushing material, the specific gravity of the metal, etc., and these factors will also change the final sorting rate due to material transportation. In short, there will be the following defects in the sorting operation: 1) Because the materials are not completely dispersed or relatively evenly spread, when the materials pass through the sorting magnetic roller, due to the large specific gravity or content of non-ferrous metals, they cannot form the so-called forward leap or the magnetic force formed by the magnetic field cannot form a repulsive force, which greatly reduces the sorting rate of metal materials and non-metal materials; 2) Because the surface of the sorting magnetic roller generates a high-frequency alternating strong magnetic field, and the partitions used cannot form a matching adjustment spacing, the partitions cannot separate metal materials and non-metallic materials at the appropriate position. Therefore, due to the inaccurate position of the partitions, the probability of mixing between metal materials and non-metallic materials is high, thereby reducing the sorting rate.
[0004] Therefore, the market is in urgent need of a sorting equipment based on eddy current sorting and material vibration dispersion, throwing and partition shifting and flipping auxiliary transmission, that is, sorting based on the core transmission. Summary of the invention
[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved material dispersing and throwing integrated conveying sorting equipment based on eddy current sorting.
[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: A material dispersing and throwing integrated conveying sorting equipment based on eddy current sorting includes a sorting conveyor belt, a sorting magnetic roller, and a sorting partition, wherein the sorting magnetic roller is located at the output end of the sorting conveyor belt. The sorting equipment also includes a vibration spreading unit arranged at the feeding end of the sorting conveyor belt, and a transfer unit linked to the strength of the magnetic field formed by the sorting magnetic roller, wherein the vibration spreading unit includes a spreading hopper that forms a step with the sorting conveyor belt and whose discharging end is located above the sorting conveyor belt, and a vibrator arranged on the spreading hopper, and the material added to the spreading hopper is shaken to the sorting conveyor belt based on the vibration of the vibrator; The transfer unit includes a shift seat located at the output end of the sorting conveyor belt and relatively close to and away from the sorting magnetic roller along the material transmission direction, and a power device driving the shift seat to move, wherein the power device and the sorting magnetic roller are connected in circuit, the sorting partition is installed on the shift seat, and the sorting partition is synchronously flipped with the movement of the shift seat to change the tilt angle, the repulsive force formed by the sorting magnetic roller is F, the vertical distance between the upper end of the sorting partition and the sorting magnetic roller is D, and the tilt angle formed by the sorting partition and the horizontal plane is θ, wherein F, D, and θ are proportional to each other; the shift seat moves from the bottom on the track extending forward and backward through rollers, and a travel roller is provided on the shift seat, the power device includes a shift power member that pushes the travel roller to roll forward or backward, and the sorting partition is synchronously flipped with the travel roller to change θ. That is, through the rolling of the travel roller, not only the forward and backward shifting can be achieved, but also the angle adjustment can be achieved.
[0007] Preferably, the top and front end of the paving hopper are open, wherein the front end forms an outlet and the top forms an inlet; the vibration direction formed by the vibrator intersects with the forward extension direction of the paving hopper, and the vibration direction is kept forward. Physical dispersion paving is implemented based on vibration shaking, so that the material is relatively evenly spread on the sorting conveyor belt.
[0008] Furthermore, a triangular base is provided on the bottom plate of the paving hopper, the triangular base has the bottom plate as the long side, and the long side is arranged horizontally, and the vibrator is vertically arranged on a short side of the triangular base, and the vibration direction is inclined forward and upward, so that the vibration can assist the loading of materials and is more conducive to the dispersion and paving of materials.
[0009] According to a specific implementation and preferred aspect of the present invention, the sorting conveyor belt includes a driving roller at the front end, a follower roller at the rear end, and an annular belt wound around the driving roller and the follower roller, wherein the upper portion of the annular belt is connected to the paving hopper to form a dispersed feeding section. Based on the continuous transmission formed by the annular conveyor belt, the magnetic field change rate of the sorting magnetic roller is reduced, making the material sorting more stable.
[0010] Preferably, the dispersing feeding section tilts upward from the back to the front to form a slope angle. Based on the inclined slope angle, the materials that may be piled together are evenly spread backward and downward, and the throwing selection is more evenly implemented.
[0011] Furthermore, the slope angle is within 20°. Generally, 2 to 8° is sufficient.
[0012] According to another specific implementation and preferred aspect of the present invention, the repulsive force F is used as a reference, and the vertical distance D and the tilt angle θ are adjusted synchronously. That is, the vertical distance D and the tilt angle θ are adjusted synchronously under the same power to optimize the structure.
[0013] Preferably, the walking roller is a gear, and the shifting power member includes a transmission chain matching the gear, a power core rod formed at both ends of the transmission chain, and an electromagnetic coil formed on the periphery of each power core rod, wherein the electromagnetic coil is connected to the sorting magnetic roller, and based on the power supply of the electromagnetic coil, the power core rod moves forward or backward to drive the gear to roll forward or backward. Through circuit control, the relationship between the intensity of the magnetic field, the vertical distance D and the tilt angle θ is realized.
[0014] According to another specific implementation and preferred aspect of the present invention, the shift seat includes a seat body located on opposite sides of the sorting conveyor belt, a connecting rod for synchronously connecting the two seat bodies, and a flip frame fixedly mounted on the connecting rod, wherein the sorting partition is fixedly mounted on the flip frame, the connecting rod is rotated around its own axis and mounted on the seat body, and the gear is fixed on the connecting rod. Angle adjustment is achieved based on the rotation of the connecting rod, and distance adjustment is implemented in the gear shifting.
[0015] Preferably, each seat body is provided with a sliding groove arranged along the front-to-back direction, and matching grooves intersecting with the sliding grooves are respectively provided at both ends of the flip frame. The transfer unit also includes a follower pin that crosses the sliding groove and the matching groove, and a guide rod installed on the seat body, wherein the guide rod penetrates the follower pin, and shifts the follower pin in the front-to-back direction as the flip frame flips. When the flipping power is lost, the follower pin relatively locks the seat body and the flip frame. The flip angle guidance is implemented during the movement of the follower pin, and the seat body and the flip frame are relatively positioned based on the positioning of the follower pin to improve the stability of the tilt angle of the sorting partition.
[0016] In some specific embodiments, there are two gears, which are located in two seat bodies, the shifting power parts are arranged one by one with the gears, and the transmission chains respectively cross the seat bodies to form a movement avoidance. This effectively improves the equal distance shifting degree and equal angle tilting of the sorting partition.
[0017] In addition, the sorting partition includes a plate body, baffle strips located on both sides of the plate body, and a receiving panel located on the top of the plate body, wherein the receiving panel is arranged tilted from top to bottom. Based on the shape of the sorting partition, it is more conducive to the transmission of sorted materials and avoids the metal materials contacting the sorting partition from accidentally scattering or mixing with non-metallic materials.
[0018] Preferably, a magnet is provided at the bottom of the receiving panel, and the magnetic field formed by the magnet further enhances the repulsive force, so that large and small particles of metal materials are thrown farther, which is more conducive to the separation of metal materials and non-metallic materials.
[0019] Furthermore, the upper end of the receiving panel is located above the center of the separation magnetic roller, so as to avoid the possibility of mixing during the throwing and selection.
[0020] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art: In the existing material sorting, because the materials are not completely dispersed or relatively evenly spread, when the materials pass through the sorting magnetic rollers, due to the large specific gravity or content of non-ferrous metals, they cannot form the so-called forward leap or the magnetic force formed by the magnetic field cannot form a repulsive force, which greatly reduces the sorting rate of metal and non-metal materials; at the same time, because the surface of the sorting magnetic roller generates a high-frequency alternating strong magnetic field, the partitions used cannot form a matching adjustment spacing, resulting in the partitions being unable to separate metal and non-metal materials at the appropriate position. Therefore, due to the inaccurate position of the partitions, the probability of mixing between metal and non-metal materials is high, thereby reducing the sorting rate and other deficiencies. The present invention designs the structure of the sorting equipment as a whole, cleverly solving the deficiencies and defects of the prior art. After the sorting equipment is used, first, a vibration is used The material is shaken off dynamically to be relatively evenly scattered to the sorting conveyor belt below, and the material is spread relatively evenly on the sorting conveyor belt; secondly, based on the magnetic field formed by the sorting magnetic roller, the repulsive force formed by the material output is scattered to sort the metal material and non-metal material; finally, based on the change of the magnetic field, the angle and distance of the sorting partition are adjusted in real time to sort the metal material and non-metal material. Therefore, on the one hand, the present invention is based on vibration shaking to form a relatively uniform dispersion and spreading of the material on the sorting conveyor belt, so that the sorting magnetic roller can sort and separate under the premise of a small change in the strong and weak magnetic field; on the other hand, based on the strong and weak magnetic fields of the sorting magnetic roller, the position and angle of the sorting partition are adjusted in real time to reduce the probability of mixing of materials during material sorting, thereby ensuring that the sorting rate of metal materials and non-metal materials of the material is higher than 98%.

[0030] Specifically, the sorting conveyor belt 1 includes an active roller 10 at the front end, a follower roller 11 at the rear end, and an annular belt 12 wound around the active roller 10 and the follower roller 11, wherein the upper part of the annular belt 12 is docked with the vibration spreading unit 4 to form a dispersed feeding section, and the sorting magnetic roller 2 is located inside the active roller 10, and forms the required high-frequency alternating strong magnetic field based on alternating current. In some specific embodiments, based on the continuous transmission formed by the annular conveyor belt, the magnetic field change rate of the sorting magnetic roller 2 is reduced, so that the material sorting is more stable. The dispersed feeding section is tilted upward from the back to the front to form a slope angle. Based on the inclined slope angle, the materials that may be piled together are evenly spread backward and downward, and the throwing selection is more evenly implemented. The angle of the slope angle is within 20°, and generally 2~8° is sufficient. In this example, the angle of the slope angle is 2.21°.

The top and front end of the paving hopper 40 are open, wherein the front end forms an outlet and the top forms an inlet; the vibration direction formed by the vibrator 41 intersects with the forward extension direction of the paving hopper 40, and the vibration direction remains forward. Physical dispersion paving is implemented based on vibration shaking, so that the material is relatively evenly spread on the sorting conveyor belt. Furthermore, a triangular base 42 is provided on the bottom plate of the paving hopper 40, and the triangular base 42 has the bottom plate as the long side, and the long side is arranged horizontally, and the vibrator 41 is vertically arranged on a short side of the triangular base 42, and the vibration direction is forward and upward. Vibration can assist in feeding, and is more conducive to the dispersion and paving of materials.
[0033] The transfer unit 5 includes a shift seat 50 located at the output end of the sorting conveyor belt 1 and relatively close to and away from the sorting magnetic roller 2 along the material transmission direction, and a power device 51 for driving the shift seat 50 to move, wherein the power device 51 is connected to the sorting magnetic roller 2 in a circuit, the sorting partition 3 is installed on the shift seat 50, and the sorting partition 3 is synchronously flipped with the movement of the shift seat 50 to change the tilt angle, the repulsive force formed by the sorting magnetic roller 2 is F, the vertical distance between the upper end of the sorting partition 3 and the sorting magnetic roller 2 is D, and the tilt angle formed by the sorting partition 3 and the horizontal plane is θ, wherein F, D, and θ are proportional to each other. In this example, the repulsive force F is used as a reference, and the vertical distance D and the tilt angle θ are adjusted synchronously. That is, the vertical distance D and the tilt angle θ are adjusted synchronously under the same power to optimize the structure.
[0034] In some specific embodiments, the shift seat 50 is moved from the bottom to the track extending forward and backward through the roller 500, and a travel roller 52 is provided on the shift seat 50, and the power device 51 includes a shift power member 510 that pushes the travel roller 52 to roll forward or backward, and the sorting partition 3 is synchronously flipped with the travel roller 52 to change θ. That is, through the rolling of the travel roller, not only the front and rear shifting can be achieved, but also the angle adjustment can be achieved. The shift seat 50 includes a seat body 50a located on opposite sides of the sorting conveyor belt 1, a connecting rod 50b for synchronously connecting the two seat bodies 50a, and a flip frame 50c fixedly mounted on the connecting rod 50b, wherein the sorting partition 3 is fixedly mounted on the flip frame 50c, the connecting rod 50b is rotated around its own axis and mounted on the seat body 50a, and the travel roller 52 is a gear, and the gear is fixed on the connecting rod 50b. Angle adjustment is achieved based on the rotation of the connecting rod, and distance adjustment is implemented in the gear shift. The shifting power member 510 includes a transmission chain a matched with the gear, a power core rod b formed at both ends of the transmission chain a, and an electromagnetic coil c formed on the periphery of each power core rod b, wherein the electromagnetic coil c is connected to the sorting magnetic roller 2, and based on the power supply of the electromagnetic coil c, the power core rod b moves forward or backward to drive the gear to roll forward or backward.

[0035] In this example, a sliding groove h is provided along the front-to-back direction on each seat body 50a, and matching grooves q are provided at both ends of the flip frame 50c to intersect with the sliding groove h. The transfer unit 5 also includes a follower pin 54 that crosses the sliding groove h and the matching groove q, and a guide rod 55 installed on the seat body 50a, wherein the guide rod 55 penetrates the follower pin 54, and shifts the follower pin 54 in the front-to-back direction as the flip frame 50c flips.

The flip angle guidance is implemented in the movement of the follower pin, and the seat body and the flip frame are relatively positioned based on the positioning of the follower pin to improve the stability of the tilt angle of the sorting partition. In some specific embodiments, there are two gears, which are located in the two seat bodies 50a, and the shifting power member 510 is arranged one by one with the gears, and the transmission chain a respectively crosses from the seat body 50a to form a motion avoidance. This effectively improves the equal distance displacement and equal angle tilt of the sorting partition.
[0036] In addition, the sorting partition 3 includes a plate body 30, baffle strips 31 located on both sides of the plate body 30, and a receiving panel 32 located on the top of the plate body 30, wherein the receiving panel 32 is arranged tilted from top to bottom. Based on the shape of the sorting partition, it is more conducive to the transmission of materials after sorting, and avoids the metal materials that contact the sorting partition from accidentally scattering or mixing with non-metallic materials. A magnet 33 is provided at the bottom of the receiving panel 32, and the magnetic field formed by the magnet further enhances the repulsive force, so that large and small particles of metal materials are thrown farther, which is more conducive to the separation of metal materials and non-metallic materials. Furthermore, the upper end of the receiving panel 32 is located above the side of the center of the sorting magnetic roller 2. The height layout avoids the probability of mixing during throwing.
[0037] The metal material hopper 6 is located in front of the non-metal material hopper 7 , and a material cover 8 is also provided on the transfer unit 5 , wherein the material cover 8 covers the sorting partition 3 and the front end, and a shielding cover 9 is also provided above the sorting conveyor belt 1 .
[0038] In summary, the implementation process of this embodiment is as follows: S1. Material spreading and dispersion The material is added from the inlet of the spreading hopper 40, and the material is shaken forward in the vibration direction formed by the vibrator 41 and scattered on the sorting conveyor belt 1 below, and the material is relatively spread on the inclined dispersion feeding section; S2, eddy current dispersion Based on the forward transmission of the dispersed feeding section and the magnetic field formed by the sorting magnetic roller 2, the repulsive force formed by the material output is thrown forward for sorting; S3, Sorting partition The angle and distance of the sorting partition 3 are adjusted in real time based on the change of the magnetic field, wherein based on the energization of the electromagnetic coil c, the power core rod b moves forward or backward to drive the gear to roll forward or backward, and the magnetic field formed by the magnet is combined to further enhance the repulsive force, so that during the material throwing and sorting, the metal material and the non-metal material are sorted and discharged from the metal material bucket 6 and the non-metal material bucket 7 respectively.
[0039] Therefore, on the one hand, the present invention is based on vibration shaking to form a relatively uniform dispersion and spreading of materials on the sorting conveyor belt, so that the sorting magnetic roller can be thrown and separated under the premise of a small change in the strong and weak magnetic fields; on the other hand, based on the strong and weak magnetic fields of the sorting magnetic roller, the position and angle of the sorting partition are adjusted in real time to reduce the probability of mixing during material throwing, thereby ensuring that the sorting rate of metal materials and non-metallic materials is higher than 98%; on the third aspect, based on vibration shaking to implement physical dispersion and spreading, the material is relatively evenly spread on the sorting conveyor belt; on the fourth aspect, based on the continuous transmission formed by the annular conveyor belt, the magnetic field change rate of the sorting magnetic roller is reduced, so that the material sorting is more stable, and at the same time, based on the inclined slope angle of the dispersed feeding section, the materials that may be piled up together are evenly spread backward and downward, and the throwing is more evenly implemented, generally 2~8°; on the fifth aspect, the vertical distance D and the inclined angle θ are adjusted synchronously under the same power to optimize the structure. At the same time, through the rolling of the walking roller, not only the forward and backward displacement can be achieved, but also the angle adjustment can be achieved, and then through circuit control, it is achieved The relationship between the strength of the magnetic field, the vertical distance D and the inclination angle θ; the sixth aspect is to realize angle adjustment based on the rotation of the connecting rod, and at the same time implement distance adjustment in the gear shift, and implement flip angle guidance in the movement of the follower pin, and at the same time, the seat body and the flip frame are relatively positioned based on the positioning of the follower pin to improve the stability of the inclination angle of the sorting partition; the seventh aspect is that there are two gears, and they are located in the two seat bodies. The shifting power parts and the gears are arranged one by one, and the transmission chains cross the seat bodies to form a movement avoidance, which effectively improves the equal distance displacement and equal angle inclination of the sorting partition; the eighth aspect is based on the shape of the sorting partition, which is more conducive to the transmission of materials after sorting, avoiding the accidental scattering or mixing of metal materials contacting the sorting partition with non-metallic materials, and a magnet is provided at the bottom of the receiving panel.
