Description

Technical Field

[0001] This utility model relates to the field of waste fragment recycling technology, specifically to a waste fragment magnetic separation device. Background Technology

[0002] In the waste recycling process, it is often necessary to separate and recover ferromagnetic materials from waste fragments to achieve resource reuse. Currently, traditional separation methods mostly rely on manual screening, which is not only costly in terms of manpower and resources but also inefficient, making it difficult to meet the needs of large-scale waste treatment. Furthermore, manual screening suffers from incomplete screening and large errors, affecting the quality of ferromagnetic material recovery. Utility Model Content

[0003] In view of the problems existing in the above-mentioned waste fragment magnetic separation device, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a magnetic separation device for waste fragments, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A magnetic separation device for waste fragments includes a base plate and a rotating drum. The rotating drum is positioned above the base plate. Multiple partitions are arranged in a circular array around the center of the rotating drum on its inner wall. Vertical plates are fixedly installed on both sides of the upper surface of the base plate. One end of the rotating drum has an opening, and a tubular electromagnet passes through the inner side of the opening. One end of the tubular electromagnet is fixedly connected to a non-magnetic tube, and one end of the non-magnetic tube is fixedly connected to a corresponding side plate. The end of the tubular electromagnet away from the non-magnetic tube is rotatably connected to the inner wall of the rotating drum. A first transmission mechanism for driving the rotating drum to rotate is located in the middle of the upper surface of the base plate. A scraper ring is slidably sleeved on the outer wall of the tubular electromagnet. A second transmission mechanism for driving the scraper ring to move is located inside the tubular electromagnet.

[0007] Preferably, the first transmission mechanism includes a first gear and a second gear. The two first gears are fixedly sleeved on the outer walls of both ends of the rotating cylinder. Two side plates are fixedly disposed in the middle of the upper surface of the base plate. A crossbar is rotatably disposed between the two side plates. The two second gears are fixedly sleeved on both ends of the crossbar. The two first gears are meshed with the corresponding second gears. A first motor is fixedly disposed on the outer wall of one side plate. The output end of the first motor is fixedly connected to one end of the crossbar.

[0008] Preferably, the second transmission mechanism includes a lead screw and a slider. The lead screw is sleeved in the middle of the tubular electromagnet, and both ends of the lead screw are rotatably connected to the corresponding vertical plates. The tubular electromagnet and the non-magnetic tube are both provided with a strip-shaped opening on their lower sides. The slider is slidably disposed inside the strip-shaped opening. The lower side of the slider is fixedly connected to the inner wall of the scraper ring, and the upper side of the slider is threadedly sleeved with the lead screw. A second motor is fixedly disposed on the outer wall of one side of the vertical plate, and the output end of the second motor is fixedly connected to one end of the lead screw.

[0009] Preferably, a receiving box is placed on the upper surface of the base plate and below the non-magnetic tube.

[0010] Preferably, both the front and rear sides of the slider abut against the inner wall of the strip opening.

[0011] Preferably, the surface of the slider and the inner wall of the strip-shaped opening are coated with a wear-resistant coating.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. In this utility model, a first motor drives a crossbar to rotate, which in turn drives a second gear to rotate a first gear, thereby causing a rotating drum to rotate. The rotating drum repeatedly pours waste fragments onto the surface of a tubular electromagnet, which can magnetically attract iron from the waste fragments, thus achieving efficient iron separation.

[0014] 2. In this utility model, the second motor drives the lead screw to rotate, causing the slider to slide inside the strip-shaped opening. This causes the scraper ring to slide along the outer wall of the tubular electromagnet, thus pushing the iron adsorbed on the surface of the tubular electromagnet to the outside of the rotating cylinder opening. When it reaches the outer wall of the non-magnetic tube, the iron loses its magnetic attraction and falls into the collection box, thus achieving automatic collection of iron.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] This utility model discloses a magnetic separation device for waste fragments.

[0023] Example 1

[0024] Reference Figure 1-3 A magnetic separation device for waste fragments includes a base plate 1 and a rotating cylinder 5. The rotating cylinder 5 is positioned above the base plate 1. Multiple partitions 7 are arranged in a circular array around the center of the rotating cylinder 5 on its inner wall. Vertical plates 2 are fixedly installed on both sides of the upper surface of the base plate 1. One end of the rotating cylinder 5 has an opening, and a tubular electromagnet 4 passes through the inner side of the opening. One end of the tubular electromagnet 4 is fixedly connected to a non-magnetic tube 3, and one end of the non-magnetic tube 3 is fixedly connected to the corresponding vertical plate 2. The end of the tubular electromagnet 4 away from the non-magnetic tube 3 is rotatably connected to the inner wall of the rotating cylinder 5. A collection box 16 is placed on the upper surface of the base plate 1 and below the non-magnetic tube 3 to facilitate the recycling of separated iron. A first transmission mechanism for driving the rotating cylinder 5 to rotate is provided in the middle of the upper surface of the base plate 1. A scraper ring 14 is slidably sleeved on the outer wall of the tubular electromagnet 4, and a second transmission mechanism for driving the scraper ring 14 to move is provided inside the tubular electromagnet 4.

[0025] Example 2

[0026] Reference Figure 1-3 The first transmission mechanism includes a first gear 6 and a second gear 10. The two first gears 6 are fixedly sleeved on the outer walls of both ends of the rotating cylinder 5. Two side plates 8 are fixedly installed in the middle of the upper surface of the bottom plate 1. A crossbar 9 is rotatably installed between the two side plates 8. The two second gears 10 are fixedly sleeved on both ends of the crossbar 9. The two first gears 6 are meshed with the corresponding second gears 10. A first motor 11 is fixedly installed on the outer wall of one side plate 8. The output end of the first motor 11 is fixedly connected to one end of the crossbar 9.

[0027] Example 3

[0028] Reference Figure 1-3The second transmission mechanism includes a lead screw 12 and a slider 15. The lead screw 12 is sleeved in the middle of the tubular electromagnet 4. The two ends of the lead screw 12 are rotatably connected to the corresponding vertical plates 2. The tubular electromagnet 4 and the non-magnetic tube 3 are both provided with strip-shaped openings on their lower sides. The slider 15 is slidably disposed inside the strip-shaped openings. The lower side of the slider 15 is fixedly connected to the inner wall of the scraper ring 14. The upper side of the slider 15 is threadedly sleeved with the lead screw 12. A second motor 13 is fixedly disposed on the outer wall of one side of the vertical plate 2. The output end of the second motor 13 is fixedly connected to one end of the lead screw 12. The front and rear sides of the slider 15 abut against the inner wall of the strip-shaped opening, so that the slider 15 can slide stably in the strip-shaped opening. The surface of the slider 15 and the inner wall of the strip-shaped opening are coated with a wear-resistant coating to improve the wear resistance of the slider 15 and the inner wall of the strip-shaped opening.

[0029] In this invention, when in use, waste fragments are poured into the rotating drum 5, and the first motor 11 and the tubular electromagnet 4 are started. The first motor 11 drives the crossbar 9 to rotate. The crossbar 9 is driven by the meshing of the second gear 10 and the first gear 6, which drives the rotating drum 5 to rotate slowly around the tubular electromagnet 4. The partition 7 inside the rotating drum 5 rotates with the drum body, continuously lifting the waste fragments and pouring them onto the outer wall of the tubular electromagnet 4. The ferromagnetic substances in the fragments are attracted to the surface of the tubular electromagnet 4 under the magnetic force of the tubular electromagnet 4, while the non-magnetic substances fall to the bottom inner wall of the rotating drum 5 under the action of gravity.

[0030] When a certain amount of ferromagnetic material is adsorbed on the surface of the tubular electromagnet 4, the second motor 13 is started. The second motor 13 drives the lead screw 12 to rotate. The lead screw 12 drives the slider 15 to slide along the strip opening towards the non-magnetic tube 3. The slider 15 drives the scraper ring 14 to move synchronously. The scraper ring 14 scrapes off the ferromagnetic material on the surface of the tubular electromagnet 4. When the scraper ring 14 moves to the area of ​​the non-magnetic tube 3, since the non-magnetic tube 3 is non-magnetic, the scraped ferromagnetic material falls into the collection box 16 below under the action of gravity to complete the collection.

[0031] After collection is completed, the second motor 13 reverses, driving the scraper ring 14 to return to the initial position of the tubular electromagnet 4, and continues to adsorb new ferromagnetic materials. The fit design of the slider 15 and the strip-shaped opening ensures that the scraper ring 14 moves smoothly, and the wear-resistant coating extends the service life of both. The partition plate 7 enhances the contact probability between the scrap and the tubular electromagnet 4, improving the magnetic separation efficiency. The whole process realizes the automatic separation and recycling of ferromagnetic materials without manual intervention, which greatly improves the processing efficiency of waste scrap.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
