Description

Technical Field

[0001] The utility model relates to the technical field of metal waste separation, and specifically relates to an eddy current separator for metals. Background Technique

[0002] Eddy current separation is an effective method for recycling non-ferrous metals. When the shredded electronic waste containing non-magnetic conductor metals (such as lead, copper, zinc, etc.) passes through an alternating magnetic field at a certain speed, induced eddy currents will be generated in these non-magnetic conductor metals. Since there is a relative movement speed between the material flow and the magnetic field, there will be a thrust on the metal sheets and blocks that generate eddy currents. Using this principle, some non-ferrous metals can be separated from the mixed material flow, and it can separate some non-ferrous metals from electronic waste.

[0003] Generally, an ordinary eddy current separator can only screen non-ferrous metals and cannot remove iron. After iron enters the eddy current separator, smaller iron blocks will fly out together with non-ferrous metals, affecting the separation effect of non-ferrous metals. Larger iron blocks will adsorb on the conveyor belt, and long-term adsorption will generate high temperature under the action of eddy currents, causing damage to the conveyor belt. For this reason, we propose an eddy current separator for metals. Content of the Utility Model

Inside the eddy current separator body 1, a multi-stage magnetic roller 2 is fixedly installed. A conveyor belt 3 is arranged between the multi-stage magnetic rollers 2. An electric motor 4 for driving the magnetic roller 2 to move is arranged outside the eddy current separator body 1. Inside the eddy current separator body 1, a primary material separation structure 5 for separating large iron blocks and a primary-secondary material separation structure 6 for separating small iron blocks are provided. A sorting plate 7 is fixedly installed inside the eddy current separator body 1, and the sorting plate 7 is arranged at the outlet of the conveyor belt 3.

[0024] The following will be a detailed description of some embodiments of the present application with reference to the accompanying drawings:

[0025] Please refer to Figures 1-4 Figure. By setting a primary material separation structure 5 at the outlet of the conveyor belt 3, non-metals and larger iron blocks adhered to the conveyor belt 3 are separated. By setting a primary-secondary material separation structure 6, non-ferrous metals and smaller iron blocks are separated, and the iron blocks in the original waste are removed.

[0026] Among them, the primary material separation structure 5 includes a first iron suction roller 8. The first iron suction roller 8 is rotatably arranged inside the eddy current separator body 1. The first iron suction roller 8 is arranged below the conveyor belt 3 and behind the outlet of the conveyor belt 3. A first scraper 9 is fixedly installed inside the eddy current separator body 1. The top of the first scraper 9 is in contact with the outer side of the first iron suction roller 8. A first collection box 10 is slidably arranged inside the eddy current separator body 1. The first collection box 10 is located below the first iron suction roller 8. A belt box 11 is fixedly installed outside the eddy current separator body 1. The electric motor 4 is fixed on the outer side of the belt box 11. The electric motor 4 drives the conveyor belt 3 and the first iron suction roller 8 to move through the belt box 11. A partition 12 is fixedly installed inside the eddy current separator body 1. The top of the partition 12 is fixedly connected to the bottom of the sorting plate 7. A second collection box 13 is arranged between the partition 12 and the first collection box 10. The second collection box 13 is slidably arranged inside the eddy current separator body 1. Non-metals and larger iron blocks are separated. The first scraper 9 is arranged directly above the first collection box 10. The bottom of the first scraper 9 is in contact with the top opening of the first collection box 10. The iron blocks that can be separated from the outer side of the magnetic roller 2 on the conveyor belt 3 are adsorbed on the first iron suction roller 8, and then the iron blocks are scraped into the first collection box 10 by the first scraper 9.

[0027] In addition, the primary and secondary material separation structure 6 includes a guiding plate 14 and a second magnetic roller 15. The guiding plate 14 is fixed inside the eddy current separator body 1, and the second magnetic roller 15 is rotatably arranged inside the eddy current separator body 1. The motor 4 drives the second magnetic roller 15 to rotate through a belt box 11. The second magnetic roller 15 is arranged outside the bottom of the opening between the guiding plate 14 and the sorting plate 7. A second scraper 16 is fixedly arranged inside the eddy current separator body 1. One end of the second scraper 16 is fixed to the partition plate 12, and the other end is in contact with the second magnetic roller 15. A third collection box 17 and a fourth collection box 18 are slidably arranged inside the eddy current separator body 1. The third collection box 17 and the fourth collection box 18 are respectively arranged on both sides of the second magnetic roller 15. The third collection box 17 is located at the bottom of the second scraper 16, and the fourth collection box 18 is located at the bottom of the guiding plate 14, which is used to separate non-ferrous metals and smaller iron blocks. A stop bar 19 is fixed on one side of the sorting plate 7 close to the second magnetic roller 15. The bottom of the stop bar 19 is in contact with the second magnetic roller 15 to prevent non-ferrous metals and iron blocks from falling to the other side of the rotation direction of the second magnetic roller 15.

[0028] It should be noted that the first scraper 9 is inclined and arranged outside the first magnetic roller 8, and the inclination direction of the first scraper 9 is opposite to the rotation direction of the first magnetic roller 8. The second scraper 16 is inclined and arranged outside the second magnetic roller 15, and the inclination direction of the second scraper 16 is opposite to the rotation direction of the second magnetic roller 15, which can better scrape off the iron blocks adsorbed on the first magnetic roller 8 and the second magnetic roller 15. Both the first scraper 9 and the second scraper 16 are made of aluminum alloy material and will not be affected by the magnetic force of the first iron block and the second iron block.

[0029] Furthermore, a plurality of placement openings are arranged outside the eddy current separator body 1. The first collection box 10, the second collection box 13, the third collection box 17, and the fourth collection box 18 are respectively fitted and arranged in the placement openings, which is convenient for replacing the first collection box 10, the second collection box 13, the third collection box 17, and the fourth collection box 18.

[0030] The waste material is sent to the outlet of conveyor belt 3 through conveyor belt 3. Affected by eddy current, non-ferrous metals and smaller iron blocks fly out and fly above sorting plate 7, and then fall onto the second magnetic iron roller 15 through the opening between guiding plate 14 and sorting plate 7. The second magnetic iron roller 15 adsorbs the iron blocks among them, and the non-ferrous metals fall into the fourth collection box 18 after the rolling of the second magnetic iron roller 15. The iron blocks on the second magnetic iron roller 15 rotate with the second magnetic iron roller 15, and finally fall off the second magnetic iron roller 15 under the scraping of the second scraper 16 and fall into the third collection box 17; non-metals are not affected by eddy current and directly fall at the outlet of conveyor belt 3 and fall into the second collection box 13; the larger iron blocks are adsorbed on conveyor belt 3 due to the action of magnetic roller 2 and move with conveyor belt 3 until they move out of the magnetic force area of magnetic roller 2. After that, the larger iron blocks are adsorbed by the first magnetic iron roller 8 and rotate with the first magnetic iron roller 8 until they are scraped off by the first scraper 9 and fall into the first collection box 10 for collection, removing the iron blocks in the original waste material and efficiently separating the iron blocks, non-metals and non-ferrous metals.

[0031] The first scraper 9 and the second scraper 16 are made of aluminum alloy, which can prevent the first scraper 9 and the second scraper 16 from being magnetized under the magnetic force of the first magnetic iron roller 8 and the second magnetic iron roller 15, and thus prevent the scraped iron blocks from being adsorbed on the first scraper 9 or the second scraper 16.
