Description

Technical Field

[0001] This invention relates to waste recycling and treatment, and in particular to a device for recycling magnetic core burrs, belonging to the field of magnetic material recycling technology. Background Technology

[0002] The magnetic core burr waste recycling device is a specialized piece of equipment used to process the burrs and debris generated during the grinding or cutting processes of magnetic cores (such as ferrite). By centrally collecting and uniformly processing the magnetic waste scattered on the production line, it effectively reduces raw material waste and lowers production costs, making it a key piece of equipment for achieving clean production and a circular economy in the magnetic materials industry.

[0003] In traditional recycling processes, conventional methods mainly rely on mechanical screening. However, the mixed waste generated during magnetic core processing is complex, often containing various impurities, such as dust fragments from angle grinder discs, iron filings from equipment wear, and even copper wire fragments and solder residues. Therefore, a separation process is required for the magnetic core waste. Although cyclone separators are a common separation method, traditional methods typically only directly introduce the separated dust-laden airflow into a bag filter for simple filtration in subsequent processing. While this mode can achieve basic magnetic powder collection, it cannot effectively separate and recover the fine powder of lightweight magnetic materials mixed in the airflow, resulting in the waste of some valuable resources along with ordinary dust, causing resource loss.

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1-11 As shown, this embodiment of the invention provides a magnetic core burr waste recycling device, including a frame 1 and a cyclone separator 2, wherein the frame 1 and the cyclone separator 2 are integrated with; Exhaust gas magnetic powder capture and recovery mechanism; connected to the gas output end of cyclone separator 2, used to efficiently capture and intercept magnetic powder particles carried in the airflow, preventing them from entering the subsequent dust removal system with light dust, thereby significantly improving the overall recovery rate and collection purity of magnetic materials. Multi-stage impurity sorting mechanism; This mechanism is integrated before the cyclone sorting process and is used to effectively separate non-magnetic impurities from other conductive metal impurities in the burr waste, so as to realize rapid pre-sorting or fine sorting of magnetic core burr waste and improve the purity of the final product.

[0025] like Figure 4 , 9 As shown, in one embodiment, a bag filter 3 is installed on the frame 1, and a connecting hose 5 is connected to the cyclone separator 2, which is connected to the bag filter 3 via the connecting hose 5. An induced draft fan 4 is also installed on the frame 1, with its induced draft end connected below the bag filter 3. An air inlet channel 30 is tangentially connected to the upper part of the cyclone separator 2's cylinder, and a discharge valve 60 is connected to the lower part of its cylinder. Utilizing the stable negative pressure generated by the induced draft fan 4 below the bag filter 3, the airflow carries the material sequentially through the cyclone separator 2 and the bag filter 3, achieving efficient centrifugal separation and dust collection of the material (magnetic core and impurities).

[0026] like Figure 9-10 As shown, in one embodiment, the exhaust gas magnetic powder collection and recovery mechanism is located in the middle section of the connecting hose 5. It includes a support plate 6 installed on the bag filter 3, a servo motor 7 installed below the support plate 6, a mounting frame 8 installed at the output end of the servo motor 7, a frame plate 9 installed on the mounting frame 8, two annular frames 10 installed on the frame plate 9, a collection groove 11 opened on the inner wall of the frame plate 9 and a magnetic plate 12 embedded therein, a groove plate 13 also installed inside the frame plate 9, a slider 14 slidably installed inside the groove plate 13, a guide post 15 and an extension plate 16 installed on the slider 14, the extension plate 16 slidably passes through the groove plate 13 and a partition plate 17 is installed at its end, a rotating plate 18 is rotatably installed inside the annular frame 10 via a bearing, a guide groove 19 opened inside the rotating plate 18, an arc-shaped block 20 installed on the rotating plate 18, and each annular frame 10 rotatably installs a magnetic plate 18 rotatably through the groove plate 13 and a magnetic plate 12 embedded therein. The frame 10 is provided with arc grooves 21, and arc blocks 20 are slidably disposed in the arc grooves 21. The upper and lower arc blocks 20 are connected to a connecting rod 22. The mounting frame 8 is equipped with a support arm 23, and the end of the support arm 23 is hinged to a telescopic cylinder 24. The output end of the telescopic cylinder 24 is hinged to the connecting rod 22. The bag filter 3 is equipped with a trough cylinder 25. Two opposing threaded blocks 26 are slidably disposed in the trough cylinder 25, and a connecting sleeve 27 is installed on each of the two threaded blocks 26. The connecting sleeves 27 are respectively installed at the two ends of the segmented cut-off connecting hose 5. A bidirectional threaded rod 28 is rotatably installed in the trough cylinder 25. A first drive motor 29 is installed above the trough cylinder 25. The bidirectional threaded rod 28 is installed at the output end of the first drive motor 29. The frame 1 is also equipped with a feeding plate 59. By driving the connecting sleeve 27 to separate and engage, the entire collection unit consisting of the frame plate 9 and the partition plate 17 can be connected to or disconnected from the airflow channel, thereby realizing online switching and maintenance of the collection unit and improving the continuity and operability of magnetic powder recovery operations.

[0027] like Figure 9-11 As shown, in one embodiment, the guide post 15 is disposed within the guide groove 19, and the partition 17 is adapted to the receiving groove 11. When the partition 17 is located within the receiving groove 11, it covers the surface of the magnetic plate 12, causing the magnetic powder to be adsorbed onto the surface of the partition 17 under the action of the magnetic field rather than directly adhering to the magnetic plate 12. This protects the magnetic plate 12 from direct contamination and wear by dust, helps maintain the long-term stability of the magnetic field of the magnetic plate 12, and extends its service life.

[0028] like Figure 9 As shown, in one embodiment, flange rings extend from both ends of the frame plate 9, and an annular groove matching the shape of the flange rings is provided on the inner side of the connection port of the connecting sleeve 27 to achieve an airtight connection. This not only ensures a strong connection but also provides good sealing performance, effectively preventing airflow short-circuiting or dust escape from the connection point, thus guaranteeing the effectiveness of the exhaust gas magnetic powder collection process.

[0029] like Figure 5 , 6 As shown, in one embodiment, the frame 1 is further provided with a crushing mechanism, including a crushing chamber 31 installed on the frame 1, a crushing motor 32 installed below the crushing chamber 31, a connecting column 33 installed at the output end of the crushing motor 32, a connecting plate 34 installed on the connecting column 33, a scraper 35 installed on the connecting plate 34, a connecting arm 36 installed at the top of the connecting column 33, a crushing roller 37 rotatably installed below the connecting arm 36, a grinding table 38 installed on the inner wall of the crushing chamber 31, and a blowing pipe 39 connected tangentially below the cylinder body; a blower 40 is also installed on the frame 1, and the air supply end of the blower 40 is connected to the blowing pipe 39; a cavity 41 is connected above the crushing chamber 31, a second drive motor 43 is installed above the cavity 41, the output end of the second drive motor 43 passes through the cavity 41 and is installed with a sorting cylinder 42; a connecting air pipe 44 is connected to the cavity 41 and is connected to the air inlet channel 30 through the connecting air pipe 44. The rising airflow generated by the blower 40 and the blower duct 39 carries the pulverized fine powder to the cavity 41. The rotating sorting cylinder 42 inside the cavity 41 uses centrifugal force to perform preliminary classification of the gas-solid mixture.

[0030] like Figure 6 As shown, in one embodiment, a feed inlet is provided on the side wall of the crushing chamber 31. The feed inlet is provided on the side wall of the crushing chamber 31 and is connected to the inclined path of the guide plate 58 at the front end, providing a direct and smooth entry point for the magnetic core material that has undergone preliminary impurity screening.

[0031] like Figure 7 , 8As shown, in one embodiment, the multi-stage impurity sorting mechanism includes a connecting frame 45, a guide plate 58 mounted on the connecting frame 45, a telescopic rod 46 mounted on the connecting frame 45, a material distribution plate 47 mounted above the telescopic rod 46, a spring 48 sleeved on the telescopic rod 46, a vibration motor 49 mounted below the material distribution plate 47, and a first sorting belt conveyor 50 and a second sorting belt conveyor 51 mounted on the connecting frame 45. The first sorting belt conveyor 50 is located upstream of the material receiving end of the second sorting belt conveyor 51, and the roller shaft of the first sorting belt conveyor 50 near the end of the second sorting belt conveyor 51 is a magnetic separator roller 52; the roller shaft of the second sorting belt conveyor 51 near the end of the guide plate 58 is a hollow roller 53, a third drive motor 55 is mounted on the side of the second sorting belt conveyor 51, and a magnetic roller 54 is mounted on the output end of the third drive motor 55. The magnetic roller 54 is rotatably installed inside the hollow roller 53. The continuous sorting unit, which combines vibratory material handling, magnetic separation for iron removal, and eddy current separation for conductive impurities, enables automated and precise separation of impurities of different properties in magnetic core burr waste.

[0032] like Figure 7 , 8 As shown, in one embodiment, the connecting frame 45 is equipped with an iron impurity collection bin 56 and a non-magnetic conductive material collection bin 57. The iron impurity collection bin 56 is located below the first sorting belt conveyor 50 and the second sorting belt conveyor 51, and is used to collect iron impurities separated by the magnetic separator roller 52. The non-magnetic conductive material collection bin 57 is located on the side of the guide plate 58 and is used to collect non-magnetic conductive impurities ejected after being sorted by the magnetic roller 54. By precisely arranging the iron impurity collection bin 56 and the non-magnetic conductive material collection bin 57 below the landing point of the force trajectory of the two-stage sorting, it is ensured that different impurities are collected efficiently and directionally.

[0033] like Figure 7 , 8 As shown, in one embodiment, one end of the spring 48 abuts against the lower part of the material distribution plate 47, and the other end abuts against the upper part of the connecting frame 45. The spring 48 provides stable and uniform elastic support and reset for the vibration system, ensuring that the material is evenly dispersed on the material distribution plate 47.

[0034] In operation, the present invention first places the burr waste material of the magnetic core to be processed into the multi-stage impurity sorting mechanism. The material is poured onto the distribution tray 47, and the vibration motor 49 drives the distribution tray 47 to generate high-frequency micro-amplitude vibration. Under the buffering and reset action of the spring 48, the material is evenly dispersed. Subsequently, the material falls onto the first sorting belt conveyor 50 and is conveyed. When the material reaches the end of the belt conveyor, the magnetic separator roller 52 below it generates a strong magnetic field, which adsorbs and carries away the ferrous magnetic impurities (such as iron filings) in the mixed waste from the main material flow. Finally, after leaving the magnetic field area, the material falls into the iron impurity collection bucket 56, thus completing the initial separation of iron impurities. The remaining material after removing the ferrous impurities falls onto the second sorting belt conveyor 51 for continued conveying. During this process, the third drive motor 55 is started, and the magnetic roller 54 located inside the hollow roller 53 begins to rotate at high speed, generating a high-frequency alternating magnetic field. When non-magnetic conductive metals (such as copper and tin) in the material pass through the magnetic field area, eddy currents are generated inside and they are subjected to electromagnetic repulsion, thus being ejected from the belt and falling into the non-magnetic conductive material collection bucket 57 on the side. The magnetic core material, which has been separated from the main metal impurities after these two stages of sorting, is concentrated and guided along the guide plate 58 and enters the feed inlet of the crushing chamber 31 along the inclined direction.

[0035] Next, the crushing motor 32 starts, driving the connecting column 33 to rotate. The connecting column 33 simultaneously drives the connecting plate 34, scraper 35, connecting arm 36, and crushing roller 37 to rotate together. During this process, the scraper 35 has an inclined angle, which quickly scoops up the waste material at the bottom and transports it to the same height as the crushing gap between the crushing roller 37 and the grinding table 38. The rotating crushing roller 37 and the grinding table 38 cooperate with each other to crush and grind the material to a finer and more uniform particle size. At the same time, the blower 40 starts, and the airflow enters the bottom of the crushing chamber 31 tangentially through the blower pipe 39. On the one hand, it carries the fine powder upward, and on the other hand, it forms a rotating airflow field, which helps to separate light and heavy materials. Finer materials carried by the airflow enter the cavity 41. At this time, the second drive motor 43 drives the sorting cylinder 42 to rotate at high speed, thereby applying centrifugal force to the rising material-containing gas, further dispersing the material and promoting airflow mixing. The mixed airflow is then introduced into the air inlet channel 30 of the cyclone separator 2 through the connecting air duct 44. Under the negative pressure generated by the induced draft fan 4, it is sucked into the cyclone separator 2. The mixed airflow of material and air enters tangentially along the upper part of the cylinder, forming a high-speed rotating vortex. During this process, the magnetic core particles with a higher specific gravity are thrown against the cylinder wall under the action of centrifugal force and spiral down along the wall surface, and are finally discharged through the discharge valve 60 at the bottom. The extremely light dust is carried by the internal swirling upward airflow and enters the exhaust gas treatment stage through the connecting hose 5.

[0036] When the exhaust gas carrying trace amounts of magnetic powder passes through the exhaust gas magnetic powder collection and recovery mechanism, the powder is adsorbed and trapped on the surface of the partition plate 17, preventing it from entering the subsequent bag filter 3. When magnetic powder collection is required, the first drive motor 29 first drives the bidirectional threaded rod 28 to rotate. Under the action of the thread, the two threaded blocks 26 and the connecting sleeve 27 move towards each other, causing the connecting hose 5 to break in the middle. Then, the servo motor 7 drives the two collectors above to rotate simultaneously. After rotating 180 degrees, the positions of the two collectors are interchanged. The collector that collects magnetic powder is now located above the feed plate 59, while the other collector is located at the connection section of the connecting hose 5. First, the collector located at the connection section of the connecting hose 5 is connected. The first drive motor 29 is started and, under the action of the thread, drives the two connecting sleeves 27 to move closer to the collector simultaneously. At the same time, the flange rings at both ends of the frame plate 9 are precisely embedded in the annular grooves on the inner side of the connecting sleeve 27 to form a sealed connection, and the collector is inserted into the airflow channel.

[0037] Next, the magnetic powder is fed into the collector located above the feed plate 59. First, the telescopic cylinder 24 is activated, pushing the connecting rod 22 to drive the arc-shaped block 20 to slide along the arc-shaped groove 21, thereby causing the rotating plate 18 to rotate. When the rotating plate 18 rotates, the guide groove 19 inside interacts with the guide post 15, forcing the slider 14 to move the extension plate 16, and causing the partition plate 17 to smoothly extend from the collection groove 11 on the inner wall of the frame plate 9. As the partition plate 17, carrying the adsorbed magnetic powder, moves away from the magnetic plate 12, the distance between the two increases, and the attraction of the magnetic field generated by the magnetic plate 12 to the magnetic powder on the surface of the partition plate 17 is significantly weakened. Under the action of gravity, the magnetic powder loses its magnetic adsorption, peels off from the surface of the partition plate 17, and falls vertically onto the feed plate 59 below, where it is collected.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
