Description

Technical Field

[0001] The invention relates to the technical field of solid waste resource treatment, in particular to an eddy current separator for separating crushed waste refrigerators. Background Art

[0002] Eddy current separation technology is used to separate non-ferrous metals from mixed particles or to separate non-ferrous metals with different conductivity (such as copper and aluminum). The main principle is that when non-magnetic metal particles pass through a changing magnetic field, alternating eddy currents will be generated inside the particles. The alternating eddy currents will generate a new magnetic field with changing direction around the particles. The directions of the two magnetic fields are opposite and repel each other. The process of separating mixed materials by using this repulsive effect is called eddy current separation.

[0003] At present, eddy current separation technology is widely used in the separation of electronic waste crushing and disassembly products, and has achieved the separation of particles with a size of 1 to 20 mm and above: "Method and equipment for separating small non-ferrous metals and insulated wire objects" (Thomas · Valerio, CN101522322A); Patent "Eddy Current Sorting Device and Method for Non-Magnetic Metals of Decommissioned Automobile Bodies" (Hua Lin et al., CN104011426A); Patent "An Intelligent Sorting Device for Non-ferrous Metal Crushed Materials" (Qin Xunpeng et al., CN104858157A); Patent "A High-Frequency Eddy Current Non-ferrous Metal Sorting Machine" (Luo Chengliang et al., CN104888955A); Patent "A Detachable Non-ferrous Metal Sorting System" (George · An, CN104689912A); Patent "A Strong Magnetic Eddy Current Separator" (Tong Jiazeng, CN103350030A); Patent "Solid Scrap Metal Sorting Equipment" (Xu Zhaotang, CN103100557A); Patent "A Magnetic Roller Outer Cylinder for Eddy Current Separator" (Zhang Chengchen et al., CN104741227A), etc.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figures 1 to 3 As shown, the present invention provides an eddy current separator for sorting waste refrigerator crushed materials, including a transmission structure 1, a partition structure 2, a material receiving structure 3, a feeding structure 4 and a material blocking structure 5, wherein the transmission structure 1 includes a belt 11, a transmission roller 12 and a magnetic roller 13, wherein the belt 11 is sleeved between the transmission roller 12 and the magnetic roller 13, and the top of the transmission structure 1 forms a conveying area gradually rising in the material conveying direction; the partition structure 2 includes a plurality of partition members 21, each of which is arranged in sequence along the width direction of the conveying area to separate the conveying area into a plurality of partition channels 22, and the top of each of the partition members 21 is spaced apart from each other. A separation channel 23 is formed between the transmission structure 1 to carry the long materials entering laterally away from the partition channel 22; the material receiving structure 3 includes a plurality of conveying material receiving troughs 31 arranged in sequence from far to near at the discharge end of the transmission structure 1, and a first door seal material receiving trough 32 provided on one side of the transmission structure 1; the feeding structure 4 has at least one driving end provided at the separation channel 23, which is used to drive the material in the separation channel 23 to fall into the first door seal material receiving trough 32; the material blocking structure 5 is provided between the conveying material receiving trough 31 and the discharge end of the transmission structure 1, so as to separate the discharge end of the transmission structure 1 so that different materials fall into the corresponding conveying material receiving trough 31.

[0029] In this device, the transmission structure 1 includes a belt 11, a transmission roller 12 and a magnetic roller 13. When in use, the material on the belt 11 is conveyed by the rotation of the conveying roller to form a conveying area on the top of the belt 11, and a partition structure 2 is set on the conveying area. The partition member 21 is used to divide the conveying area into multiple partition channels 22, so that the long materials and other crushed materials entering longitudinally can enter the partition channel 22 and be conveyed to the discharge end of the transmission structure 1. A plurality of conveying material receiving troughs 31 are arranged in sequence from far to near at the discharge end of the transmission structure 1, and the conveying material receiving trough 31 and the transmission structure are connected. 1, separates the discharge end of the transmission structure 1, so that the material can fall into the corresponding conveying receiving trough 31 for collection under the action of the magnetic field of the magnetic roller 13 and the guiding action of the material blocking structure 5, thereby realizing magnetic separation and classification of the material, and the long material entering laterally is transported to the separation channel 23 above it through the obstruction of the partition piece 21, and cooperates with the feeding structure 4 to drive the material in the separation channel 23 to fall into the first door seal receiving trough 32 on the other side of the transmission structure 1, thereby realizing stable and efficient separation of various components.

[0030] In order to move the long materials entering laterally away from the partition channel 22, in some embodiments, a guide surface 24 is formed on the top side of the partition piece 21 near the feed end of the transmission structure 1. The guide surface 24 is gradually inclined upward and extends from the top surface of the belt 11 along the material conveying direction, and can guide the door seal gradually upward along the material conveying direction. In order to further improve the conveying efficiency of the door seal, an electric drive roller is provided on the guide surface 24, and the rotation direction of the electric drive roller is consistent with the material conveying direction, so that when the electric drive roller is rotated by electric drive, the door seal can be transferred to the top of the partition piece 21 through the guide surface 24, avoiding the situation of material pile blockage at the guide surface 24, and at the same time facilitating the subsequent use of the feeding structure 4 to drive the door seal from the other side to fall into the first door seal receiving trough 32 for collection. It should be noted that in other embodiments, the electric drive roller can also be replaced by other drive structures, such as providing multiple rotating push plates to push the material forward, which can drive the door seal to move above the partition member 21, and is not limited here.

[0031] Several partition members 21 can divide the conveying area into multiple partition channels 22. In some embodiments, each of the partition members 21 includes a partition plate, wherein the partition plate is arranged along the material conveying direction and is fixed by a separate bracket or other structure so that the belt 11 will not drive the partition plate to move when it is running, so as to divide the area above the belt 11 into multiple partition channels 22. The width of the partition channel 22 does not exceed 100 mm and the height does not exceed 100 mm for the crushed material to enter. An opening is also provided between the guide surfaces 24 on the top side of each of the partition plates, and a sealing structure is provided on the part of the top side of each of the partition plates near the discharge end of the transmission structure 1. Specifically, an integral or separate top plate can be provided on the partition plate to seal the part between the top sides of the partition plate and near the discharge end of the transmission structure 1, so that the position corresponding to the guide surface 24 is open, so as to facilitate the provision of an electric drive roller on the partition plate and drive it using the electric drive roller.

[0032] The guide surface 24 extends from the top surface of the belt 11 gradually upward along the material conveying direction. Figure 1 As shown, in some embodiments, the guide surface 24 can have a variety of different shapes. For example, the guide surface 24 can be set to an arcuate surface by cutting the upper left side of the separator into an arcuate surface that gradually extends upward. For another example, the guide surface 24 can be set to a straight inclined surface. In this case, the straight inclined surface is formed by cutting the upper left side of the separator into a plane that gradually extends upward. It should be noted that the guide surface 24 formed on the top side of the partition member 21 near the feed end of the transmission structure 1 is not limited to an arcuate surface or a straight inclined surface, and can also be other shapes that can convey the door seal entering laterally onto the partition member 21 moving in the direction of material advancement.

[0033] The crushed products of waste refrigerators include powdered foam, granular and block-shaped metals, cables, plastics of various shapes, and long strips of PVC door seals. The particle length distribution ranges from less than 1 mm to 600 mm. During the sorting process, small particles of foam may be mixed in the material and cannot be separated. In order to achieve the separation of powdered foam, in some embodiments, the feeding structure 4 includes a plurality of fans 42. Specifically, in this embodiment, three fans 42 are provided according to the length of the conveying area. The three fans 42 are arranged in sequence along the material conveying direction, and the exhaust outlets 41 of each fan 42 are provided on the side of the separation channel 23 away from the first door seal receiving trough 32, so that the exhaust outlets 41 are provided in sequence at the setting positions of the separation channel 23 and the first door seal receiving trough 32. On the opposite side and facing the partition channel 23, the three exhaust ports 41 all correspond to the first door seal receiving trough 32, and the exhaust port 41 of the first fan 42 is set at the feed end of the transmission structure 1. During implementation, the door seal that cannot enter the partition channel 22 is horizontal on the partition structure. In order to prevent the material from being blocked by the horizontal door seal and causing stacking, the fan 42 and the electric drive roller are required to take it away. At this time, the first fan 42 causes the lighter door seals and foam to fall directly from the side of the belt 11 into the first door seal receiving trough 32, and the electric drive roller causes the door seals that are not blown away by the fan 42 to move in the direction of material advancement and be transferred to the top of the partition structure 2, thereby being again affected by the second and third fans 42 and falling into the first door seal receiving trough 32 for collection.

[0034] Furthermore, in other embodiments, the feeding structure 4 is a pushing structure composed of a cylinder and a push plate, which can push the door seal to the top of the first door seal receiving groove 32 at the separation channel 23.

[0035] In order to achieve the separation of various crushed materials and door seals, in some embodiments, several of the conveying material receiving troughs 31 are respectively the second door seal receiving trough 311, the non-ferrous metal receiving trough 312, the non-metallic material receiving trough 313 and the magnetic metal receiving trough 314 at the discharge end of the transmission structure 1, so as to respectively receive the long materials (door seals, etc.), non-ferrous metals (copper, aluminum, etc.), non-metals (such as plastics, etc.) and magnetic metals (such as iron, etc.) entering and conveying longitudinally, wherein the magnetic metal receiving trough 314 is located at the positive side of the magnetic roller. Below, the non-metallic material receiving trough 313 is located on one side below the magnetic roller, so that when the magnetic metal is conveyed to the discharge end of the belt 11, it is adsorbed on the side of the belt 11 outside the magnetic roller 13 under the action of the magnetic field of the magnetic roller 13. Under the transportation of the belt 11, the magnetically selected metal is driven to the bottom of the magnetic roller, and the magnetic attraction of the magnetic roller 13 on the magnetic metal gradually disappears, causing the magnetic metal to fall into the magnetic metal receiving trough 314. A material discharge baffle can also be set on one side of the slot of the magnetic metal receiving trough 314 to allow the magnetically selected metal to be blocked by the material discharge baffle and fall.

[0036] Specifically, in order to achieve the separation of door seals, non-ferrous metals, and non-metals, in some embodiments, the blocking structure 5 includes a first blocking member 51 and a second blocking member 52, one end of the first blocking member 51 is arranged on the side of the discharge end of the transmission structure 1 and is spaced from the transmission structure 1, and the other end thereof extends to between the second door seal receiving trough 311 and the non-ferrous metal receiving trough 312, so that a plurality of the first blocking members are away from the side of the transmission structure 1 to form a door seal channel corresponding to the second door seal receiving trough 311, and since the conveying area gradually rises from the material conveying direction, and the door seal entering longitudinally is longer, the door seal entering longitudinally is carried on the first blocking member 51 when it leaves the magnetic roller 13. And it is carried to the second door seal receiving trough 311 at the bottom through the door seal channel; one end of the second stopper 52 is arranged between the transmission structure 1 and the first stopper 51 to separate the first stopper 51 and the transmission structure 1 to form a non-ferrous metal channel and a non-metallic channel, and the non-ferrous metal channel and the non-metallic channel correspond to the non-ferrous metal receiving trough 312 and the non-metallic material receiving trough 313 respectively, wherein the channel close to the transmission structure 1 is a non-metallic channel, and the other is a non-ferrous metal channel. Non-metal enters the non-metallic material receiving trough 313 directly through the non-metallic channel under the action of gravity, and non-ferrous metal enters the corresponding non-ferrous metal receiving trough 312 through the non-ferrous metal channel under the action of the magnetic repulsion force of the magnetic roller 13.

[0037] In some embodiments, multiple conveying material receiving troughs 31 are formed by separating baffles within a trough structure. Specifically, a first baffle 33, a second baffle 34 and a third baffle 35 are respectively arranged between the second door seal material receiving trough 311, the non-ferrous metal material receiving trough 312, the non-metallic material receiving trough 313 and the magnetic metal material receiving trough 314, and multiple trough structures are formed by the first baffle 33, the second baffle 34 and the third baffle 35, wherein the first baffle 33 is fixed between the second door seal material receiving trough 311 and the non-ferrous metal material receiving trough 312, and the second baffle 34 and the third baffle 35 are respectively slidably arranged between the non-metallic material receiving trough 313 and the non-ferrous metal material receiving trough 312 and the magnetic metal material receiving trough 314 and the non-metallic material receiving trough 313.

[0038] In order to adapt to the second baffle 34 that can slide and adjust the position, the first baffle 51 includes at least two fourth baffles 511, and the second baffle 52 includes at least one fifth baffle 521. Specifically, in this embodiment, there are three fourth baffles 511 and two fifth baffles 521. The three fourth baffles 511 are rotatably connected in sequence, and the connecting joints are fixed, so that the upper fourth baffle 511 can rotate along the connecting joints to correspond to the adjustment position, so as to ensure that the highest point of the fourth baffle 511, which is arranged at the top of one side of the transmission structure 1 and is located at the top, is not higher than the highest point of the magnetic roller 13, and the vertical distance between the highest point of the magnetic roller 13 and the fourth baffle 511 does not exceed 200 mm, and becomes smaller as the size of the material decreases, so that the longitudinal entry door seal can be smoothly loaded on the fourth baffle 511 when it is separated from the magnetic roller 13. The fourth baffle 511 located at the bottom is arranged above the first baffle 33; the fifth baffle 521 is arranged between the fourth baffle 511 and the transmission structure 1, and is spaced from the first material stop 51 and the transmission structure 1 on both sides. One end of the two fifth baffles 521 is rotatably connected and can rotate along its joint to adjust the position. One end of the fifth baffle 521 at the bottom extends to between the magnetic metal material receiving trough 314 and the non-metallic material receiving trough 313, and it can rotate along the upper joint according to the position of the second baffle 34 to adjust the inclination, and the second baffle 34 and the fifth baffle 521 can realize synchronous left and right movement. The smaller the material size, the second baffle 34 and the fifth baffle 521 are closer to the left, and the inclination angle of the fifth baffle 521 at the bottom with the horizontal is reduced; the top fifth baffle 521 can rotate along its lower end joint to adjust the size of the corresponding channels on both sides.

[0039] Furthermore, in some embodiments, the first door seal receiving trough 32 and the second door seal receiving trough 311 are both provided with a filter 321, and a vibration device capable of driving the filter 321 to vibrate is provided, so that the foam powder falls under the screen and separates the foam powder from the door seal.

[0040] The above embodiments are merely multiple possible implementations of the embodiments of the present application, and the embodiments of the present application are not limited thereto.

[0041] In order to further improve the separation efficiency of foam and door seals entering laterally, in some embodiments, the eddy current separator for sorting waste refrigerator crushed materials also includes a vibrating feeding mechanism 6, the guide end of the vibrating feeding mechanism 6 extends from the direction away from the transmission structure 1 to the direction close to the transmission structure 1 and downwardly inclined to correspond to the receiving structure 3, so as to transport the crushed materials and the door seals entering longitudinally to the partition channel 22, and the foam and the door seals entering laterally are blown into the first door seal receiving trough 32 by the vibration of the vibrating feeding mechanism 6 when falling; wherein, the guide end of the vibrating feeding mechanism 6 and the feeding area of ​​the transmission structure 1 are inclined at a certain angle θ to the horizontal, and 0≤θ≤30°, so that the foam powder particles are blown away as much as possible by the fan 42 at the connection between the feed and the conveyor belt to the bottom receiving trough.

[0042] Furthermore, the specific form of the vibrating feeding mechanism 6 is not limited, as long as it can realize vibratory feeding. In this embodiment, the vibrating feeding mechanism 6 is composed of a feeding trough, a vibration exciter, a spring support, a transmission device, etc. The vibration source of the vibrating feeding is the vibration exciter, which is composed of two eccentric shafts (active and passive) and a gear pair. The active shaft is driven by an electric motor through a V-belt, and the gear on the active shaft meshes with the passive shaft to rotate. The active and passive shafts rotate in opposite directions at the same time, causing the feeding structure to vibrate and achieve the purpose of conveying materials.

[0043] It should be noted that the rotation of the transmission roller 12 is driven by the motor connected to it, the longitudinal cross-sectional length of the magnetic roller pole is set to range from 50mm to 200mm, the magnetic field strength on the surface of the magnetic roller is not less than 4000GS, and the thickness of the belt 11 is selectable from 5 to 20mm. The purpose is to allow the non-ferrous metal particles of different sizes produced by crushing to form induced eddy currents smoothly after adjustment and receive the correct eddy currents, and pass through the fifth baffle 521 into the corresponding receiving trough.

[0044] Furthermore, all motors involved in this embodiment are variable frequency motors.

[0045] Working principle: During implementation, PVC door seals, magnetic metals, non-metals, non-ferrous metals and other crushed materials are fed to the top of the belt 11 through the vibrating feeder, and the PVC door seals and other crushed materials entering vertically can enter the partition channel 22 and be transported through the belt 11. Under the action of the first fan 42, the lighter door seals and foams fall directly from the side of the belt 11 into the first door seal receiving trough 32, and the electric drive roller makes the door seals that are not blown away by the fan 42 move in the direction of material advancement and are transferred to the top of the partition structure 2, and then are again affected by the second and third fans 42 and fall into the first door seal receiving trough 32; the door seals that enter vertically are longer, and they are Under the conveyance of the belt 11, it is carried on the first material stopper 51 when it separates from the magnetic roller 13, and is carried to the second door seal receiving trough 311 at the bottom through the door seal channel. Under the action of gravity, non-metallic materials directly enter the non-metallic receiving trough 313 through the non-metallic channel. Non-ferrous metals enter the corresponding non-ferrous metal receiving trough 312 through the non-ferrous metal channel under the action of the magnetic repulsion force of the magnetic roller 13. The magnetic metal is adsorbed on the side of the belt 11 outside the magnetic roller 13 under the action of the magnetic field of the magnetic roller 13. Under the conveyance of the belt 11, after the magnetically selected metal is driven to the bottom of the magnetic roller, the magnetic attraction of the magnetic roller 13 on the magnetic metal gradually disappears, causing it to fall into the magnetic metal receiving trough 314.

[0046] The present invention provides a partition structure 2 on the conveying area by setting a partition structure 2, a material receiving structure 3, a feeding structure 4 and a material blocking structure 5. The partition structure 2 is used to divide the conveying area into multiple partition channels 22 by using a partition member 21, so that the long materials and other crushed materials entering longitudinally can enter the partition channel 22 and be conveyed to the discharge end of the transmission structure 1.
