Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separation equipment, in particular to a magnetic separation equipment for environmentally friendly recycling of waste electronic components. Background Art

[0002] Waste electronic devices, commonly known as "e-waste", refer to electrical or electronic equipment that is no longer used and is discarded. It mainly includes obsolete electronic technology products such as refrigerators, air conditioners, washing machines, televisions, and communication electronic products such as computers. E-waste needs to be handled with caution. In some developing countries, the phenomenon of e-waste is very serious, and the environmental pollution caused threatens the health of local residents.

[0003] After searching, it was found that the publication number is CN212493460U, and the name is a magnetic separation device for environmentally friendly recycling of waste electronic components. The application proposes that when waste electronic components are processed, the useful metals inside them need to be magnetically separated and extracted before they can be incinerated or buried. The existing magnetic separation equipment has a single structure and is only adsorbed by magnet bars, which makes metal impurities easy to accumulate and fall, and the collection effect is poor. The metal impurities in the waste are adsorbed by the grid structure, and the scraper can reciprocate to scrape the metal impurities on the metal rod, so that the metal impurities can be scraped to the upper side of the second discharge barrel, and the relay controls the electromagnet By intermittently cutting off the power, the metal impurities can be discharged. Compared with the traditional magnetic separation equipment, an automatic scraping mechanism is added to avoid the accumulation and falling of metal impurities, and the metal components in the electronic devices can be collected and reused. However, this application needs to be intermittently cut off during use. When the power is off, magnetic separation cannot be performed, resulting in discontinuous operation and low efficiency. At the same time, this application uses a variety of electrical equipment such as motors and electromagnets, which have a complex structure and require frequent power outages. The operation is troublesome, and the grille is prone to blockage, resulting in poor stability in use. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0027] According to an embodiment of the utility model, a magnetic separation device for environmentally friendly recycling of waste electronic components is provided.

[0028] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4As shown, according to an embodiment of the utility model, a magnetic separation device for environmentally friendly recycling of waste electronic components includes a magnetic separation cylinder 1 and a discharge port 3. The discharge ports 3 are opened on both sides of the magnetic separation cylinder 1, and a mounting frame 4 is fixedly mounted inside the discharge port 3, and a roller frame 11 is fixedly mounted on the top surface of the mounting frame 4.

When magnetic separation of waste electronic components is performed, the crushed waste electronic components can be put into the magnetic separation cylinder 1 from the top opening of the magnetic separation cylinder 1.

The components slide down and hit the conveyor belt 14, and the strong magnetic block 8 generates magnetic force. The magnetic force penetrates the conveyor belt 14 and absorbs the magnetic metal materials in the waste electronic components. The magnetic metal materials can adhere to the surface of the conveyor belt 14. At the same time, the driving motor 16 drives the driving roller 10 to rotate, and then drives the conveyor belt 14 to rotate upward. The magnetic metal materials attached to the surface of the conveyor belt 14 can move upward to the discharge port 3. As the conveyor belt 14 flips over to the top of the mounting frame 4, when the magnetic metal materials move between the fixing plate 7 and the mounting frame 4, the magnetic metal materials are out of the magnetic force range of the strong magnet and fall to the mounting frame 4. The top surface of the mounting rack 4 slides down the mounting rack 4 to the discharge port 5, while other waste electronic components pass through the magnetic separation cylinder 1 and are discharged along the bottom of the magnetic separation cylinder 1. The device can continuously and automatically complete the magnetic separation of waste electronic components, with high working efficiency and simple and convenient use. At the same time, the device generates magnetic force through the strong magnetic block 8 and the magnetic cylinder 12 to magnetically separate the waste electronic components, and only uses the driving motor 16 as the driving source. The structure is very simple and the control and use are very convenient. At the same time, the opening gap between the conveying belts 14 is large, and no clogging will occur, thereby improving the smoothness of the magnetic separation and the stability of the work.

[0029] In one embodiment, the driving roller 10 is rotatably connected to the roller frame 11 through the roller shaft 13, and a motor frame 15 is fixedly installed on the surface of one side of the roller frame 11, and a driving motor 16 is fixedly installed on the other end of the motor frame 15, and the output end of the driving motor 16 is fixedly connected to one end of the roller shaft 13.

[0033] In one embodiment, the roller shaft 13 is rotatably connected to the roller frame 11 via a bearing, which is a common installation structure.

[0034] Working principle:

[0035] When magnetic separation of waste electronic components is performed, the crushed waste electronic components can be put into the magnetic separation cylinder 1 from the top of the magnetic separation cylinder 1. After being diverted and guided by the herringbone plate 2, the waste electronic components slide down and hit the conveyor belt 14. The strong magnetic block 8 generates magnetic force, and the magnetic force penetrates the conveyor belt 14 to absorb the magnetic metal materials in the waste electronic components. The magnetic metal materials can be attached to the surface of the conveyor belt 14. At the same time, the driving motor 16 drives the driving roller 10 to rotate, thereby driving the conveyor belt 14 to rotate upward, and the magnetic metal materials attached to the surface of the conveyor belt 14 can move upward to the discharge port 3. As the conveyor belt 14 turns over to the top of the mounting frame 4, when the magnetic metal materials move to the fixing plate 7 When the magnetic material is between the strong magnetic block 8 and the mounting frame 4, the magnetic metal material escapes the magnetic force range of the strong magnet, falls to the top surface of the mounting frame 4, slides down the mounting frame 4 to the discharge port 5, and other waste electronic components pass through the magnetic separation cylinder 1 and are discharged along the bottom of the magnetic separation cylinder 1. The device can continuously and automatically complete the magnetic separation of waste electronic components, with high working efficiency and simple and convenient use. At the same time, the device generates magnetic force through the strong magnetic block 8 and the magnetic cylinder 12 to magnetically separate the waste electronic components, and only uses the driving motor 16 as the driving source. The structure is very simple and the control and use are very convenient. At the same time, the opening gap between the conveying belts 14 is large, and no clogging will occur, thereby improving the smoothness of the magnetic separation and improving the stability of the work.
