Description

Technical Field

[0001] The present invention relates to the technical field of sorting devices, and in particular to a garbage sorting system and control method based on magneto-electric coordination. Background Art

[0002] Garbage sorting is a key pre-processing step in waste disposal. Its efficiency and accuracy directly impact subsequent resource utilization and harmless treatment. The garbage sorting system is an automated device that uses technical means to achieve garbage classification. Its core function is to quickly and intelligently identify and separate mixed waste streams, solving the pain points of low efficiency, large errors, and high costs of manual sorting at the source. It also lays a solid foundation for subsequent resource recycling and harmless treatment.

[0003] In the process of sorting mine waste, waste sorting systems usually incorporate technologies such as magnetic separation, electrostatic separation, and high-voltage electric field separation to accurately select metal-containing mineral particles from waste rock, clay, dust and other impurities in ore tailings, fully tapping the resource value of mine waste and laying the foundation for subsequent harmless treatment of mine waste.

[0004] However, when faced with special treatment objects with complex components such as mine waste, the current garbage sorting system has insufficient sorting accuracy and cannot cover all types of valuable minerals. It is difficult to effectively identify and separate mine waste, resulting in the omission of some target minerals, which limits the improvement of resource recovery rate.

[0016] A control method for a garbage sorting system based on magneto-electric coordination:

[0017] S1: Receiving and crushing the original mine waste, and subsequently transporting the crushed mine waste: The mine waste is fed into the crusher, which starts and performs the crushing operation according to the preset waste processing capacity and crushing particle size requirements. The crushed mine waste will fall from the crusher's discharge port into the feeding area of ​​the vibrating feeder. When the vibrating feeder is powered on, the conveying mechanism on it starts, and at the same time, its feeding chute generates periodic vibration to transport the crushed particles;

[0018] S2: The magnetic separator screens the mine waste: The crushed particles are transported to the upper end of the magnetic separator by the vibrating feeder and fall onto the magnetic drum from top to bottom. The magnetic field around the drum attracts the crushed particles with a high magnetic metal content or composed entirely of magnetic metal. As the drum rotates, the adsorbed crushed particles are transported to an area with a weaker magnetic field. Under the action of gravity, they fall off the surface of the drum and fall into the first collection box. The crushed particles with a low magnetic metal content or no magnetic metal at all are thrown into the receiving frame as the drum rotates.

[0019] S3: The sorting box component supplements the screening work of the magnetic separator: Under the action of the magnetic field of the magnetic drum, some crushed particles containing magnetic metals are not thrown into the receiving frame with the rotation of the magnetic drum, nor are they transported to the weaker magnetic field area with the rotation of the magnetic drum and then fall into the first collection box. Instead, they will be thrown into the box unit. Some particles are intercepted by the receiving component close to the magnetic separator, some particles are intercepted by the receiving component far away from the magnetic separator, and some particles are intercepted by the intercepting component.

[0020] S4: The sorting box assembly neatly stores particles and collects dust: the particles come into contact with the receiving assembly and roll downward on the rotating rod assembly set in the inter-plate groove along the tilt direction of the rotating plate, and are then intercepted by the rubber. When the rotating plate is subjected to pressure from particles exceeding a certain limit, the hinge rotates in the rotating shaft and causes the fixed rotating plate to rotate downward, squeezing the spring and folding the spring. When the rotating plate rotates, the sleeve embedded inside is displaced. At this time, the PE line in the sleeve is relatively displaced with it, and the sealing plug is pulled to slide in the strip hole. At this time, part of the air in the elastic inflatable corrugated tube enters the strip hole through the air hole. The air pressure inside the elastic inflatable bellows drops, and its supporting force weakens, causing the particles in contact with it to reshape their shape and migrate. The dust on the surface of the particles will fall from the gaps between the multiple rotating rod components and fall into the receiving tray. The particles will come into contact with the interception components, and the particles that fall on the steel plate will collide with the crushing blocks set on the steel plate and break into pieces. They will then be caught by the receiving net, and the dust on the surface will pass through the receiving net and fall into the receiving tray. If the receiving tray is full of dust, the receiving tray can be pulled out of the sorting box body. At this time, the dust will pass through the strip grooves opened in the transverse partition and fall into the temporary receiving tray. After cleaning the receiving tray, reset it, and then clean the temporary receiving tray.

[0021] S5: The eddy current separator screens the mine waste. The particles on the receiving frame fall onto the sorting conveyor belt. After being transported through the permanent magnetic roller in the sorting conveyor belt, the particles with greater repulsion will be thrown into the fourth collection box. The particles with greater magnetic attraction will be adsorbed and transported to the lower end of the sorting conveyor belt. Under the action of gravity, they fall off the sorting conveyor belt and are screened into the second collection box. The particles that are not affected by repulsion and magnetism will fall on the inclined surface of the inclined block due to inertia and slide into the third collection box.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, through the setting of the sorting box assembly, the device can effectively intercept and collect the mine waste that is sorted by the magnetic separator and the eddy current separator, covering multiple types of minerals such as magnetic and non-magnetic, high conductive and low conductive minerals, broadening the sorting range, ensuring the comprehensive sorting of various valuable minerals in the mine waste, and fully tapping the diversified resource value in the mine waste.

[0024] 2. In the present invention, in the sorting box assembly, the receiving assembly can support the magnetic metal particles that are collaboratively sorted by the magnetic separator and the eddy current separator, thereby achieving smooth, flexible guidance and uniform distribution of the materials. The intercepting assembly can buffer the impact of the materials and pre-treat the materials, thereby enhancing the sorting effect of complex materials. The protective assembly can effectively disperse and buffer the impact force generated when the materials fall or move, reducing the direct impact of the materials on other components, thereby extending the service life of the equipment, preventing the materials from deviating from the preset path due to impact, and indirectly ensuring the stability of the sorting process. The receiving tray and the temporary receiving tray can achieve efficient collection of impurities separated from the materials.

[0025] 4. In the present invention, the arc-shaped setting of the rotating plate, the elastic support of the folding spring, and the rolling support surface of the rotating rod assembly enable the material to be evenly spread in the sorting box, reducing accumulation and blockage. The ingenious combination of the elastic inflatable bellows tube, sealing plug block, and PE line in the rotating rod assembly can further promote the reconstruction of the material accumulation shape, avoid uneven sorting caused by local accumulation, flexibly adjust the flow state of the material, and prevent material accumulation or overflow.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0053] See also Figures 1-16 , the present invention provides a technical solution:

[0054] A garbage sorting system and control method based on magneto-electric cooperation, comprising a crusher 1, a vibrating feeder 2, a magnetic separator 3 and an eddy current separator 4, the discharge port of the crusher 1 is connected to the feeding area of ​​the vibrating feeder 2, the bottom end of the discharge area of ​​the vibrating feeder 2 is fixedly connected to the magnetic separator 3, the eddy current separator 4 is placed on the side of the magnetic separator 3 away from the vibrating feeder 2, a sorting box assembly 5 is placed between the magnetic separator 3 and the eddy current separator 4, the sorting box assembly 5 comprises a box unit 51, a receiving tray 52 is slidably provided in the box unit 51, a temporary receiving tray 53 is slidably provided in the box unit 51, a receiving assembly 54 is installed in the box unit 51, an intercepting assembly 55 is bonded and fixed to the inner wall of the box unit 51 on the side away from the magnetic separator 3, a protective assembly 56 is snap-fitted and installed in the box unit 51, and the box unit 51 comprises a sorting The sorting box body 511 has a vertical partition 514 fixedly connected to the sorting box body 511, and a support block 515 is fixedly connected to the right side of the vertical partition 514. The receiving component 54 includes a hinge 541, and a rotating shaft 542 is inserted and rotated in the hinge 541. The two ends of the rotating shaft 542 are fixedly connected to a rotating plate 543, and the lower end of the rotating plate 543 is fixedly connected to a folding spring 544. The upper end of the rotating plate 543 is bonded and fixed with a rubber 545. An inter-plate groove 546 is provided on the inner side of the rotating plate 543, and a rotating rod assembly 547 is provided in the inter-plate groove 546. A sleeve 548 is embedded and installed on the inner side of the hinge 541. The magnetic separator 3 and the eddy current separator 4 cooperate to sort mine waste of various components and improve the comprehensiveness of sorting. The sorting box component 5 cooperates with the magnetic separator 3 to optimize the sorting accuracy, reduce material mixing, and improve the recovery rate of metal resources.

[0055] As a further implementation of this solution, the magnetic separator 3 includes a roller support frame 31, a hydraulic rod 32 is welded and fixed on the upper end of the roller support frame 31, and a magnetic drum 33 is fixed to the upper end of the roller support frame 31 by bolts. A first collecting box 34 is placed under the magnetic drum 33, and the upper end of the hydraulic rod 32 supports the vibrating feeder 2. The magnetic field strength of the magnetic drum 33 is 800Oe~1500Oe. The vibrating feeder 2 is supported by the hydraulic rod 32, which provides a certain stability and helps to maintain the coordination of the entire feeding and magnetic separation process. The magnetic field strength of the magnetic drum 33 can avoid energy waste and excessive adsorption of non-target impurities while ensuring effective adsorption of target magnetic substances, thereby ensuring sorting accuracy. At the same time, moderate magnetic field strength can also reduce the energy loss of the magnetic drum 33 to a certain extent, as well as reduce the friction between the material and the magnetic drum 33, slow down its surface wear, and reduce the operating cost of the equipment.

[0056] As a further implementation of this solution, the eddy current separator 4 includes a machine frame 41, a material receiving frame 42 is welded and fixed on the upper end of the machine frame 41, a sorting conveyor belt 43 is installed on the inner side of the machine frame 41, and a bevel block 44 is fixedly connected to the side of the machine frame 41 away from the material receiving frame 42. The bevel block 44 is horizontally projected into a triangle. A second collecting box 45 is placed under the sorting conveyor belt 43, and a third collecting box 46 is placed on the side of the second collecting box 45 that is consistent with the conveying direction of the sorting conveyor belt 43. A fourth collecting box 46 is placed on the side of the third collecting box 46 away from the second collecting box 45. Box 47, the second collection box 45 can allow some materials containing residual magnetic metals to be adsorbed by the sorting conveyor belt 43 and then thrown into it, the third collection box 46 can allow some materials without metals to slide along the inclined surface of the inclined block 44 to the third collection box 46 after being thrown away by the sorting conveyor belt 43, and the fourth collection box 47 is used to collect high-conductivity materials containing high non-ferrous metal content, which are subject to the strongest eddy current force and are ejected the farthest. Such a setting can effectively avoid the mixing of materials of different properties, which is conducive to the subsequent targeted treatment, recycling and reuse of different types of materials.

[0057] As a further implementation of this solution, a temporary receiving tray 53 is arranged below the receiving tray 52. ​​The temporary receiving tray 53 and the receiving tray 52 are parallel to each other. There are two receiving components 54 and two protective components 56, and the positions of the two correspond one to one. The upper end surface of the intercepting component 55 and the upper end surface of the box unit 51 are on the same horizontal plane. When there is excessive material on the receiving tray 52, the receiving tray 52 can be taken out for cleaning. At this time, the temporary receiving tray 53 can temporarily replace the receiving tray 52 for receiving. The design that there are two receiving components 54 and two protective components 56 and the positions correspond one to one enables the two to work together better to guide the material into the designated area and prevent the material from running off or accidentally overflowing.

[0058] As a further implementation of this solution, the four corner areas at the bottom of the sorting box body 511 are connected to foot cups 512, and the front and rear sides of the sorting box body 511 are installed with lifting rings 513. A transverse partition 516 is provided in the sorting box body 511, and the transverse partition 516 is provided between the receiving tray 52 and the temporary receiving tray 53. A plurality of strip grooves are provided in the transverse partition 516. Auxiliary pulleys 517 are provided in the sorting box body 511, and the auxiliary pulleys 517 are provided in groups of two. A total of several groups of two groups of auxiliary pulleys 517 are provided. The foot cup 512 can be adjusted in height by rotation, which can easily cope with the problem of uneven ground and ensure that the sorting box body 511 always remains horizontal and stable. At the same time, the contact area between the foot cup 512 and the ground is small, which can reduce friction resistance when moving the equipment, making it convenient for short distances. From the adjusted position, the installation of the lifting ring 513 can provide a stable force point when the sorting box body 511 needs to be transported, hoisted or shifted as a whole, avoiding damage to components during transportation, and improving the safety and convenience of movement. The setting of the cross partition 516 not only supports the receiving tray 52, but also allows the dust above the receiving tray 52 to fall into the temporary receiving tray 53 when the receiving tray 52 is moved. The multiple sets of auxiliary pulleys 517 can convert the sliding friction between the receiving tray 52 and the temporary receiving tray 53 and the sorting box body 511 into rolling friction when they are moved, greatly reducing the resistance between components, avoiding jamming, reducing wear and extending the service life of the sorting box body 511.

[0059] As a further implementation of this solution, the side of the rotating plate 543 close to the folding spring 544 is arc-shaped, and the lower end of the folding spring 544 is fixedly connected to the support block 515. The rubber 545 is bonded and fixed to the side of the sorting box body 511 close to the hinge 541. There are several rotating rod assemblies 547, and the multiple rotating rod assemblies 547 are parallel to each other and evenly and equidistantly distributed in the inter-plate groove 546. The arc edge can reduce the friction resistance and jamming risk when contacting with other components compared to right angles or acute angles. The folding spring 544 has a retractable and buffered elastic property, and the support block 515 fixed at its lower end provides a stable force foundation. When the rotating plate 543 carries a lot of material, it can compress the folding plate 543. The stacked spring 544 changes its own angle so that the carried material can be evenly spread on the rotating plate 543. The design of the rubber 545 bonded to the sorting box body 511 near the hinge 541 forms a flexible sealing structure. When the rotating plate 543 rotates around the hinge 541, the rubber 545 can deform synchronously with the plate body to fill the gap between the rotating plate 543 and the sorting box body 511. Multiple rotating rod assemblies 547 are arranged in parallel and evenly in the inter-plate groove 546 to form a regular "rolling support surface". When the material moves in the inter-plate groove 546, the rolling of the rotating rod assembly 547 can convert sliding friction into rolling friction, greatly reducing the movement resistance and allowing the material to be better spread on the rotating plate 543.

[0060] As a further implementation of this solution, the interception component 55 includes a rubber sheet 551. The side of the rubber sheet 551 that is not in contact with the sorting box body 511 is bonded and fixed with a steel plate 552. The side of the steel plate 552 away from the sorting box body 511 is fixedly connected with a number of crushing blocks 553. The bottom end of the steel plate 552 is fixedly connected with a receiving net 554. The side of the receiving net 554 away from the steel plate 552 is fixedly connected with a vertical partition 514. The rubber sheet 551 has good elasticity and flexibility. As the contact body between the interception component 55 and the sorting box body 511, the rubber sheet 551 has good elasticity and flexibility. 51 can cushion the impact force by deformation, which can not only prevent the material from being broken and worn due to hard collision, but also some materials with low magnetic metal content will fly into the sorting box body 511 and impact the steel plate 552. The crushing blocks 553 on the outside of the steel plate 552 will collide and squeeze the materials. The raised structure of the crushing blocks 553 can initially crush or disperse the materials mixed with metals and ores, and pre-process them for re-sorting. The grid structure of the receiving net 554 can filter out impurities falling from the surface of the materials, leaving slightly larger particles that still need further processing.

[0061] As a further implementation of this solution, the protective component 56 includes a cover tile 561, and the bottom end of the cover tile 561 is fixedly connected to a supporting elastic sheet 562, and a spring strip 563 is provided between the cover tile 561 and the supporting elastic sheet 562. The two ends of the spring strip 563 are respectively fixedly connected to a first clamping block 564, and the bottom end of the supporting elastic sheet 562 is fixedly connected to a second clamping block 565. The first clamping block 564 and the second clamping block 565 are exactly the same in shape. The first clamping block 564 and the second clamping block 565 are simultaneously clamped on the upper end of the vertical partition 514. The cover tile 561, the supporting elastic sheet 562 and the spring strip 563 are all arc-shaped. The cover tile 561 is at the outermost layer of the protective component 56. Its arc structure can effectively disperse and buffer the impact force generated when the material falls or moves, reduce the direct impact of the material on other components, play a good protective role, thereby extending the service life of the equipment, and the supporting elastic sheet 562 is connected to the cover tile 561. When the cover tile 561 is in the state of being moved, the spring strip 563 is inserted between the cover tile 561 and the supporting elastic sheet 562. This elastic supporting structure can not only further absorb the impact energy of the material, but also enable the cover tile 561 to quickly return to its original position after being impacted, thereby maintaining the stability and integrity of the protective assembly 56. The design of the first clamping block 564 and the second clamping block 565 enables the various components of the protective assembly 56 to be easily connected and fixed. During installation, it is only necessary to align and clip the corresponding first clamping block 564 and the second clamping block 565 into the fixed position of the corresponding vertical partition 514 in the sorting box body 511 to quickly complete the installation, thereby improving the installation efficiency and convenience. The arc profile of the cover tile 561, the supporting elastic sheet 562 and the spring strip 563 can fit the movement trajectory of the material more closely, reducing the hard contact between the material and the protective component, and avoiding the material from bouncing off the preset path after hitting the protective assembly 56, thereby indirectly ensuring the stability of the sorting process.

[0062] As a further implementation of this solution, the rotating rod assembly 547 includes a roller core 5471, a strip hole 5472 is opened on the inner side of the roller core 5471, an air hole 5473 is opened in the roller core 5471, a sealing plug 5474 is slidably connected to the inner side of the strip hole 5472, and a PE line 5475 is fixedly connected to one side of the sealing plug 5474. A rotating sleeve roller 5476 is rotatably connected to the outer side of the roller core 5471, and one end of the rotating sleeve roller 5476 is fixedly connected to an elastic inflatable corrugated tube 5477. Both ends of the roller core 5471 are fixedly connected to a rotating plate 543 at the same time. The strip hole 5472 is connected to the sleeve 548, and the inner side of the elastic inflatable corrugated tube 5477 is connected to the strip hole 5472 through the air hole 5473. The outer side of the sealing plug 5474 is tightly attached to the inner side of the strip hole 5472, and the PE line 5475 is slidably inserted in the sleeve 548. The end of 75 that is not connected to the air hole 5473 is fixedly connected to the box unit 51, and two rotating rollers 5476 are fixedly connected to both ends of the elastic inflatable corrugated tube 5477. The sealing plug 5474 slides in the strip hole 5472, and its outer side is tightly attached to the inner side of the strip hole 5472 to form a seal. At the same time, the elastic inflatable corrugated tube 5477 is connected to the strip hole 5472 through the air hole 5473, so that the sealing plug 5474 can move flexibly in the strip hole 5472, and the sealing is guaranteed. When the PE line 5475 is pulled in the roller core 5471, the air pressure of the elastic inflatable corrugated tube 5477 can be controlled by the sealing plug 5474. The internal air pressure of the elastic inflatable corrugated tube 5477 drops, and its supporting force on the material is weakened, so that the shape of the material deposit is reconstructed and the position is migrated. The change in flow conditions enables the material to be evenly spread.

[0063] Workflow: receiving and crushing the original mine waste, and then transporting the crushed mine waste: the mine waste is fed into the crusher 1, which starts and performs the crushing operation according to the preset waste processing capacity and crushing particle size requirements. The crushed mine waste will fall from the discharge port of the crusher 1 into the feeding area of ​​the vibrating feeder 2. When the vibrating feeder 2 is powered on, the conveying mechanism on it starts, and at the same time, its feeding trough generates periodic vibration to transport the crushed particles;

[0064] The magnetic separator 3 performs screening operations on the mine waste: the crushed particles are transported to the upper end of the magnetic separator 3 by the vibrating feeder 2 and fall from top to bottom onto the magnetic drum 33. The magnetic field around the magnetic drum 33 attracts the crushed particles with a high magnetic metal content or composed entirely of magnetic metal. As the magnetic drum 33 rotates, the attracted crushed particles are transported to an area with a weaker magnetic field. Under the action of gravity, they fall off the surface of the magnetic drum 33 and fall into the first collection box 34. The crushed particles with a low magnetic metal content or no magnetic metal at all are thrown into the receiving frame 42 as the magnetic drum 33 rotates.

[0065] The sorting box assembly 5 supplements the screening work of the magnetic separator 3: Under the action of the magnetic field of the magnetic drum 33, some of the crushed particles containing magnetic metals are not thrown into the receiving frame 42 with the rotation of the magnetic drum 33, nor are they transported to the area with weaker magnetic field with the rotation of the magnetic drum 33 and then fall into the first collecting box 34. Instead, they will be thrown into the box unit 51. Some particles are intercepted by the receiving assembly 54 close to the magnetic separator 3, some particles are intercepted by the receiving assembly 54 far away from the magnetic separator 3, and some particles are intercepted by the intercepting assembly 55.

[0066] The sorting box assembly 5 neatly stores and collects particles: the particles come into contact with the receiving assembly 54 and roll downward on the rotating rod assembly 547 provided in the inter-plate groove 546 along the tilting direction of the rotating plate 543, and are then intercepted by the rubber 545. When the rotating plate 543 is subjected to pressure from particles exceeding a certain limit, the hinge 541 rotates within the rotating shaft 542 and causes the fixedly connected rotating plate 543 to rotate downward, squeezing the spring folding spring 544. When the rotating plate 543 rotates, the sleeve 548 embedded inside is displaced. At this time, the PE line 5475 in the sleeve 548 is displaced relative to it, and the sealing plug 5474 is pulled to slide in the strip hole 5472. At this time, a portion of the air in the elastic inflatable corrugated tube 5477 enters the strip hole through the air hole 5473. In 5472, as the air pressure inside the elastic inflatable bellows 5477 drops, its supporting force weakens, causing the particles in contact with it to undergo morphological reconstruction and position migration. The dust on the surface of the particles will fall from the gaps between the multiple rotating rod assemblies 547 and fall into the receiving tray 52. ​​The particles will contact the interception assembly 55, and the particles falling on the steel plate 552 will collide with the crushing blocks 553 provided on the steel plate 552 and break. They will then be received by the receiving net 554, and the dust on the surface will pass through the receiving net 554 and fall into the receiving tray 52. ​​If the receiving tray 52 is full of dust, the receiving tray 52 can be pulled out of the sorting box body 511. At this time, the dust will pass through the strip grooves provided in the transverse partition 516 and fall into the temporary receiving tray 53. After the receiving tray 52 is cleaned and reset, the temporary receiving tray 53 is then cleaned.

[0067] The eddy current separator 4 performs screening operations on the mine waste; the particles on the receiving frame 42 fall onto the sorting conveyor belt 43, and are transported through the permanent magnetic roller in the sorting conveyor belt 43. The particles with greater repulsion will be thrown into the fourth collection box 47, and the particles with greater magnetic attraction will be adsorbed and transported to the lower end of the sorting conveyor belt 43. Under the action of gravity, they fall off the sorting conveyor belt 43 and are screened into the second collection box 45. The particles that are not affected by repulsion and magnetism will fall on the inclined surface of the inclined block 44 due to inertia and slide into the third collection box 46.

[0068] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

10. A control method for a garbage sorting system based on magneto-electric coordination according to any one of claims 1 to 9, characterized in that: S1: Receiving and crushing the original mine waste, and subsequently transporting the crushed mine waste: the mine waste is put into the crusher (1), and the crusher (1) starts and performs the crushing operation according to the preset waste processing volume and crushing particle size requirements. The crushed mine waste will fall from the discharge port of the crusher (1) into the feeding area of ​​the vibrating feeder (2). After the vibrating feeder (2) is powered on, the conveying mechanism on it starts, and at the same time, its feeding trough generates periodic vibration to transport the crushed particles; S2: The magnetic separator (3) performs screening operations on the mine waste: the crushed particles are transported to the upper end of the magnetic separator (3) by the vibrating feeder (2) and fall from the top to the bottom on the magnetic roller (33). The magnetic field around the magnetic roller (33) will attract the crushed particles with a high magnetic metal content or composed entirely of magnetic metals. As the magnetic roller (33) rotates, the adsorbed crushed particles will be transported to an area with a weaker magnetic field. Under the action of gravity, they will separate from the surface of the magnetic roller (33) and fall into the first collection box (34). The crushed particles with a low magnetic metal content or no magnetic metal at all will be thrown into the receiving frame (42) as the magnetic roller (33) rotates. S3: The supplementary part of the screening work of the magnetic separator (3) by the sorting box component (5): a part of the crushed particles containing magnetic metals are not thrown into the receiving frame (42) with the rotation of the magnetic drum (33) under the action of the magnetic field of the magnetic drum (33), nor are they transported to the weak magnetic field area with the rotation of the magnetic drum (33) and then fall into the first collecting box (34). They will be thrown into the box unit (51), some particles are intercepted by the receiving component (54) close to the magnetic separator (3), some particles are intercepted by the receiving component (54) far away from the magnetic separator (3), and some particles are intercepted by the intercepting component (55); S4: The sorting box assembly (5) neatly stores and collects particles: the particles contact the receiving assembly (54) and roll downward on the rotating rod assembly (547) provided in the inter-plate groove (546) along the tilting direction of the rotating plate (543), and are then intercepted by the rubber (545). When the rotating plate (543) is subjected to the pressure of the particles exceeding a certain limit, the hinge (541) rotates in the rotating shaft (542) and causes the fixed rotating plate (543) to rotate downward, squeezing the spring folding spring (544). When the rotating plate (543) rotates, the sleeve (548) embedded in the inner side is driven to move. At this time, the PE line (5475) in the sleeve (548) moves relative to it and pulls the sealing plug (5474) to slide in the strip hole (5472). At this time, a part of the air in the elastic inflatable corrugated tube (5477) enters through the air hole (5473). In the strip hole (5472), as the internal air pressure of the elastic gas-filled bellows (5477) decreases, its supporting force weakens, causing the particles in contact with it to undergo morphological reconstruction and position migration. The dust on the surface of the particles will fall from the gaps between the multiple rotating rod components (547) and fall into the receiving plate (52). The particles will come into contact with the interception component (55). The particles that fall on the steel plate (552) will react with the crushing blocks (553) set on the steel plate (552). The dust collides and breaks, and is then received by the receiving net (554). The dust on the surface passes through the receiving net (554) and falls into the receiving tray (52). If the receiving tray (52) is full of dust, the receiving tray (52) can be pulled out of the sorting box body (511). At this time, the dust passes through the strip groove opened in the transverse partition (516) and falls into the temporary receiving tray (53). After cleaning the receiving tray (52), it is reset and the temporary receiving tray (53) is cleaned. S5: The eddy current separator (4) performs screening operations on the mine waste; the particles on the receiving frame (42) fall on the sorting conveyor belt (43), and are transported through the permanent magnetic roller in the sorting conveyor belt (43). The particles with greater repulsive force will be thrown into the fourth collection box (47), and the particles with greater magnetic attraction will be adsorbed and transported to the lower end of the sorting conveyor belt (43). Under the action of gravity, they fall off the sorting conveyor belt (43) and are screened into the second collection box (45). The particles that are not affected by repulsive force and magnetic force will fall on the inclined surface of the inclined block (44) due to inertia and slide into the third collection box (46).
