Description

Technical Field

[0001] This invention relates to the field of glass recycled aggregate impurity removal technology, specifically a fine sorting and impurity removal device for glass recycled aggregate used in substations. Background Technology

[0002] A large amount of waste glass components are generated during substation renovation, expansion, equipment maintenance, and operation and maintenance upgrades. These mainly include glass insulators, tempered protective glass, equipment translucent glass, and insulating protective glass. After crushing and coarse filtration, this type of waste glass can be processed into recycled glass aggregate, which can replace traditional sand and gravel in substation site hardening, cable trench grouting, and civil engineering repairs. This effectively realizes the resource utilization of power solid waste, reduces the construction and operation and maintenance costs of substations, and aligns with the green and low-carbon development concept of the power industry.

[0003] Currently, existing glass recycled aggregate sorting and impurity removal equipment has several substantial shortcomings in the processing of aggregates for substations. Firstly, traditional equipment often uses direct feeding and conveying, resulting in uneven material accumulation and buildup during transport. Fine metallic impurities are easily encapsulated and buried within the glass aggregate, leading to low impurity exposure and significant blind spots, making precise impurity removal impossible. Secondly, most existing impurity removal devices only employ a single permanent magnet iron removal structure, capable of removing only ferromagnetic metallic impurities. They cannot effectively separate non-magnetic conductive micro-impurities such as copper, aluminum, and stainless steel. Residual conductive particles mixed within the aggregate significantly reduce the insulation performance of the substation's civil engineering concrete, easily causing safety hazards such as leakage and grounding short circuits, failing to meet the safety standards for substation electrical equipment foundations.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-11This invention provides a technical solution: a fine sorting and impurity removal device for recycled glass aggregate in substations, comprising an impurity removal box 1, a smoothing and conveying assembly installed inside the impurity removal box 1, a magnetic metal removal assembly installed inside the impurity removal box 1, a conductive metal removal assembly installed inside the impurity removal box 1, a feeding cylinder 5 installed inside the impurity removal box 1, a pick-and-place plate 6 fixedly installed on the outer side of the top of the feeding cylinder 5, a screening screen 55 fixedly installed inside the feeding cylinder 5, and a reduction motor 2, a reduction motor 3, and a reduction motor 4 fixedly installed on one side of the impurity removal box 1. A collection frame 8 is slidably installed inside one end of the waste bin 1. Two partitions 12 are symmetrically fixed inside the collection frame 8. The conductive metal removal assembly includes a second conveyor belt 9 and an outer sleeve 32. Two drive rollers 10 are movably installed inside the second conveyor belt 9. One end of the first conveyor belt 44 is located at the top of one end of the second conveyor belt 9, and the two drive rollers 10 are rotatably installed inside the waste bin 1. One end of one drive roller 10 is fixedly connected to the output end of a second reduction motor 3. Two flat plates 11 are fixedly installed inside the waste bin 1. The second 11 contacts the top and bottom of the inner cavity of the second 9 conveyor belt, respectively. A fixing connecting plate 33 is fixedly installed on the outer side of the outer sleeve 32, and the end of the fixing connecting plate 33 away from the outer sleeve 32 is fixedly connected to the inner side of the impurity removal box 1. An end cover plate 40 is bolted to one side of the outer sleeve 32, and a motor mounting base 30 is fixedly installed on one side of the end cover plate 40. A drive motor 29 is fixedly installed inside one side of the motor mounting base 30. A transmission wheel 31 is fixedly installed at the output end of the drive motor 29, and the end of the transmission wheel 31 away from the drive motor 29 rotates. An inner rotating post 39 is fixedly installed on the through end cover plate 40. A fixing collar 41 is fixedly installed on the outer side of one end of the inner rotating post 39. A plurality of assembly rods 38 are fixedly installed on one side of the fixing collar 41. Outer S-class arc magnets 37 and outer N-class arc magnets 36 are installed at intervals on the outer side of the plurality of assembly rods 38. Assembly slots 35 are opened inside the outer S-class arc magnets 37 and outer N-class arc magnets 36, and the assembly rods 38 are inserted into the inner side of the assembly slots 35. A threaded ring 34 is threadedly connected to the end of the inner rotating post 39 away from the transmission wheel 31.

[0030] The working principle of the above technical solution is as follows: Crushed and coarsely filtered substation glass recycled aggregate is fed into the feeding cylinder 5. The screening screen 55 inside the feeding cylinder 5 performs secondary pre-screening of the aggregate, further intercepting large uncrushed particles, hard lumps, and coarse impurities, achieving material pre-treatment and purification. After being processed by the smoothing and conveying component and the magnetic metal removal component, the aggregate falls onto the conductive metal removal component's conveyor belt 9. The reduction motor 3 drives the transmission roller 10 to rotate, causing the conveyor belt 9 to transport the material. The flat plate 11 ensures the smoothing and conveying of the material. The conveyor belt 29 runs smoothly and without vibration. The output end of the drive motor 29 drives the inner rotating column 39 to rotate at high speed inside the fixed outer sleeve 32. The inner rotating column 39 is alternately equipped with the outer S-class arc magnet 37 and the outer N-class arc magnet 36 through the fixed collar 41 and the assembly rod 38. During the high-speed rotation, a high-frequency alternating magnetic field is formed. When the aggregate passes through the magnetic field area, non-magnetic conductive micro-impurities such as copper, aluminum, and stainless steel are induced to generate eddy currents, generate a reverse magnetic field, and are subjected to lateral repulsive force, causing trajectory deviation and complete separation from the insulating glass aggregate, thus achieving precise removal of non-magnetic conductive impurities.

[0031] In another implementation scheme, such as Figures 1-11 As shown, the smoothing and conveying assembly includes a conveyor belt 52. Drive rollers 53 are movably mounted inside both ends of the conveyor belt 52. One end of one drive roller 53 is fixedly connected to the output end of a reduction motor 4. Baffle plates 18 are installed at both ends of the conveyor belt 52, and the two drive rollers 53 are rotatably mounted between the two baffle plates 18. Fixed connecting plates 17 are fixedly installed on opposite sides of the baffle plates 18, and sealing plates 51 are fixedly installed on opposite sides of the baffle plates 18. The bottom of the sealing plates 51 contacts the top of the conveyor belt 52. A flat plate 50 is fixedly installed on the opposite side, and the distance between the bottom of the flat plate 50 and the top of the conveyor belt 3 52 is two centimeters. The end of the fixed connecting plate 2 17 away from the baffle plate 2 18 is fixedly connected to both sides of the inner cavity of the impurity removal box 1. Two flat plates 3 54 are fixedly installed on the opposite side of the baffle plate 2 18, and the two flat plates 3 54 are in contact with the top and bottom of the inner side of the conveyor belt 3 52, respectively. The bottom of the feeding cylinder 5 is in contact with the top of the sealing plate 51, the flat plate 50 and the two baffle plates 2 18, and the bottom of the feeding cylinder 5 is located between the sealing plate 51 and the flat plate 50.

[0032] The crushed and coarsely filtered recycled glass aggregate from the substation is fed into the feeding cylinder 5. The screening screen 55 inside the feeding cylinder 5 performs secondary pre-screening of the aggregate, further intercepting large uncrushed particles, hard lumps, and coarse impurities, thus achieving material pre-treatment and purification. After passing through the filter screen, the material falls onto the conveyor belt 3 52 of the smoothing and conveying component. The geared motor 3 4 drives the transmission roller 3 53 to rotate, causing the conveyor belt 3 52 to transport the material at a uniform speed. The baffle plate 2 18 and the sealing plate 51 form a closed feeding area to prevent material spillage and dust leakage. The flat spreading plates 50 with fixed intervals scrape and spread the accumulated aggregate, and together with the flat plate 3 54, support the inner side of the conveyor belt 3 52 to ensure that the material is transported in a uniform thin layer, preventing material stacking and impurity accumulation, laying the foundation for subsequent precise impurity removal.

[0033] In another implementation scheme, such as Figures 1-11As shown, the magnetic metal removal assembly includes a conveyor belt 44 and a mounting frame 16. Two drive rollers 48 are mounted on the inner side of the conveyor belt 44. One end of one drive roller 48 is fixedly connected to the output end of a reduction motor 2. Baffle plates 13 are mounted on both sides of the conveyor belt 44, and the two drive rollers 48 are rotatably mounted between the two baffle plates 13. Two flat plates 49 are fixedly mounted on opposite sides of the baffle plates 13, and the two flat plates 49 contact the top and bottom of the inner side of the conveyor belt 44, respectively. Sliding grooves 14 are provided on the inner sides of both baffle plates 13. A cleaning magnet 42 is fixedly installed at the bottom of the mounting frame 16. Multiple gap combs 43 are also fixedly installed at the bottom of the mounting frame 16. A sliding straight bar 15 is fixedly installed on one side of the mounting frame 16. A sliding U-shaped bar 47 is fixedly installed on the side of the mounting frame 16 away from the sliding straight bar 15. Elliptical blocks 27 are fixedly installed at both ends of the sliding U-shaped bar 47. The bottom of the gap combs 43 contacts the top of the conveyor belt 44. The sliding U-shaped bar 47 and the sliding straight bar 15 are slidably installed inside two sliding grooves 14. A fixed connecting plate 45 is fixedly installed at the bottom of the baffle plate 13. Both ends of 45 are fixedly connected to the inner side of the impurity removal box 1. One end of the conveyor belt 3 52 is located at the top of one end of the conveyor belt 1 44. Two bracket blocks 19 are fixedly installed on one side of the impurity removal box 1, and rotating rods 24 are movably installed inside the two bracket blocks 19. Two rotating protrusions 20 are installed on the outer side of the rotating rods 24, and the two rotating protrusions 20 are in opposite positions. A transmission wheel 1 21 is fixedly installed on the outer side of the rotating rods 24. A transmission belt 22 is driven to the outer side of the transmission wheel 1 21 and the transmission wheel 2 31. A rectangular groove 23 is opened on one side of the impurity removal box 1, and the transmission wheel 1 21 is located inside the rectangular groove 23. On one side of the impurity removal box 1, two limiting sleeves 56 are fixedly installed, and sliding blocks 25 are slidably installed on the inner side of each limiting sleeve 56. A top block 26 is fixedly installed on the top of each sliding block 25. A sliding groove 28 is opened on one side of the impurity removal box 1, and the end of the sliding U-shaped strip 47 is slidably installed on the inner side of the sliding groove 28. The outer side of the top block 26 is in contact with the outer side of the elliptical block 27. The positions of the rotating protrusion 20 and the sliding block 25 are corresponding. A protective cover 7 is fixedly installed on one side of the impurity removal box 1. The protective cover 7 is located outside the rotating rod 24, the sliding block 25, the top block 26 and the elliptical block 27.

[0034] The flattened aggregate is conveyed to the end by conveyor belt 352 and falls onto conveyor belt 144 of the magnetic metal removal component. Gear motor 12 drives transmission roller 148 to rotate, causing conveyor belt 14 to feed the aggregate at a uniform speed. Flat plate 149 provides inner support for conveyor belt 144 to ensure smooth conveying. Mounting frame 16 is slidably mounted inside the sliding groove 14 of baffle plate 13 via sliding straight bar 15 and sliding U-shaped bar 47. The impurity removal magnet 42 at the bottom continuously generates a static magnetic field, adsorbing magnetically conductive impurities such as iron filings and iron inserts from the aggregate. The densely arranged gap combs 43 at the bottom connect with conveyor belt 14... 4. The surface is well-fitted, which can comb and disperse the aggregate, avoid material accumulation, improve the coverage of magnetic impurity removal, and thoroughly remove the fine magnetic metal impurities buried inside the aggregate. During the rotation of the rotating rod 24, the rotating protrusion 20 in the opposite position periodically pushes the sliding block 25, so that the sliding block 25 slides vertically along the limiting sleeve 56, which drives the pushing block 26 to reciprocate to press the elliptical block 27, and drives the sliding U-shaped strip 47 to slide back and forth in conjunction with the mounting frame 16, thereby driving the impurity removal magnet 42 and the gap comb 43 to move dynamically, avoiding the accumulation and adsorption of magnetic impurities and clogging of the comb teeth, realizing automatic impurity removal and ensuring continuous impurity removal effect.

[0035] In another implementation scheme, such as Figures 1-11 As shown, two combing plates 46 are symmetrically fixedly installed at the bottom of the fixed connecting plate 45, and one side of the combing plate 46 is in contact with one end of the conveyor belt 9.

[0036] At the same time, the combing plate 46 at the bottom of the fixed connecting plate 45 separates the aggregate and conductive metal at the discharge end of the conveyor belt 9, effectively preventing the backflow and mixing of conductive metal impurities after offset separation, further enhancing the sorting accuracy, and thoroughly distinguishing pure glass aggregate from non-ferrous metal impurities.

[0037] Working principle: The crushed and coarsely filtered substation glass recycled aggregate is fed into the feeding cylinder 5. The screening screen 55 inside the feeding cylinder 5 performs secondary pre-screening of the aggregate, further intercepting large uncrushed particles, hard lumps and coarse impurities, realizing material pre-treatment and purification. After passing through the filter screen, the material falls above the conveyor belt 3 52 of the smoothing and conveying component. The geared motor 3 4 drives the transmission roller 3 53 to rotate, driving the conveyor belt 3 52 to convey the material at a uniform speed. The baffle plate 2 18 and the sealing plate 51 form a closed feeding area to prevent material spillage and dust leakage. The flat spreading plate 50 with fixed spacing scrapes and spreads the accumulated aggregate, and together with the flat plate 3 54 supports the inner side of the conveyor belt 3 52, ensuring that the material is conveyed in a uniform thin layer, eliminating material stacking and impurity accumulation, laying the foundation for subsequent precise impurity removal. The flattened aggregate is conveyed to the end by the three-conveyor belt 52 and falls onto the conveyor belt 44 of the magnetic metal removal component. The geared motor 2 drives the transmission roller 48 to rotate, which drives the conveyor belt 44 to feed the aggregate at a uniform speed. The flat plate 49 provides inner support for the conveyor belt 44 to ensure smooth conveying. The mounting frame 16 is slidably installed inside the sliding groove 14 of the baffle plate 13 through the sliding straight bar 15 and the sliding U-shaped bar 47. The impurity removal magnet 42 at the bottom continuously generates a static magnetic field to adsorb magnetic conductive impurities such as iron filings and iron inserts in the aggregate. The densely arranged gap comb 43 at the bottom is attached to the surface of the conveyor belt 44 to comb and disperse the aggregate, avoid material accumulation, improve the magnetic impurity removal coverage, and thoroughly remove the fine magnetic metal impurities buried inside the aggregate. After the magnetic impurities are removed, the aggregate falls from the end of the first conveyor belt 44 onto the second conveyor belt 9 of the conductive metal removal component. The second reduction motor 3 drives the second transmission roller 10 to rotate, which in turn drives the second conveyor belt 9 to transport the material. The second flat plate 11 ensures that the second conveyor belt 9 runs smoothly and without shaking. The drive motor 29 drives the rotating rod 24 to rotate through the second transmission wheel 31, the transmission belt 22, and the first transmission wheel 21. The inner rotating column 39 rotates at high speed inside the fixed outer sleeve 32. The inner rotating column 39 is alternately equipped with the outer S-class arc magnet 37 and the outer N-class arc magnet 36 through the fixed collar 41 and the assembly rod 38. During the high-speed rotation, a high-frequency alternating magnetic field is formed. When the aggregate passes through the magnetic field area, non-magnetic conductive micro-impurities such as copper, aluminum, and stainless steel are induced to generate eddy currents, generate a reverse magnetic field, and are subjected to lateral repulsive force, causing trajectory deviation and complete separation from the insulating glass aggregate, thus achieving precise removal of non-magnetic conductive impurities. During the rotation of the rotating rod 24, the rotating protrusion 20 in opposite positions periodically pushes the sliding block 25, causing the sliding block 25 to slide vertically along the limiting sleeve 56. This drives the jacking block 26 to reciprocate to press the elliptical block 27, which in turn drives the sliding U-shaped strip 47 to slide back and forth along the entire mounting frame 16. This causes the impurity removal magnet 42 and the gap comb 43 to move dynamically, preventing magnetic impurities from accumulating and clogging the comb teeth, thus achieving automatic impurity removal and ensuring continuous impurity removal effect. At the same time, the combing plate 46 at the bottom of the fixed connecting plate 45 separates the aggregate and conductive metal at the discharge end of the conveyor belt 9, effectively preventing the backflow and mixing of conductive metal impurities after offset separation, further enhancing the sorting accuracy, and thoroughly distinguishing pure glass aggregate from non-ferrous metal impurities. Finally, the pure glass aggregate that has undergone double impurity removal is transported to the end of the impurity removal box 1 and falls into the sliding collection frame 8. The internal partition 12 achieves classified collection, completing the entire set of fine sorting and impurity removal operations. The outer protective cover 7 of the device provides closed protection for the transmission and sliding structure, preventing dust and materials from interfering with the operation of the equipment.
