By performing magnetic attraction and demagnetization operations on the iron filings in the waste copper, the iron filings are separated from the waste copper.

Description

Technical Field

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

[0002] Copper is one of the earliest metals used by mankind and is an important resource. Copper is mostly used in electrical, light industry, machinery manufacturing, construction industry, and defense industry. In order to reduce the waste of resources, scrap copper is recycled. In the process of scrap copper recycling, it is particularly important to remove magnetic metal impurities such as iron from the scrap copper.

[0003] Utility model patent CN223381699U discloses a crushing device for recycling waste copper, including a shell. Support feet are fixedly connected to the bottom of the shell, and a feed trough is fixedly connected to the top of the shell. A pressure roller is rotatably connected to the inner wall of the shell, and a gear is fixedly connected to one end of the pressure roller. A first motor is fixedly connected to the surface of the shell. Discharge ports are opened on both sides of the shell near the bottom. An mounting plate is snapped onto the surface of the shell, and bolts are threaded through the surface of the mounting plate. A magnetic cylinder is fixedly connected to the inner wall of the mounting plate. A roller is rotatably connected inside the shell. A second motor is fixedly connected to the surface of the shell. A sliding column is slidably installed inside the shell, and a scraper is fixedly connected to one side of the sliding column. First, an appropriate amount of raw material is fed into the trapezoidal feed trough 3. The first motor 6 is started by an external power source. The first motor 6 drives the gear 5 to drive two pressure rollers 4 to rotate inward, crushing the raw material. The crushed material falls onto the surface of the roller 14, where an inclined plate 7 limits the material. The second motor 13 is started by an external power source, controlling the roller... As the drum 14 rotates, copper material falls onto one side of the ramp 8 under the conveyor of the drum 14 and is discharged from the discharge port 9 on one side. Iron filings and other waste materials are attracted to the surface of the drum 14 by the magnetic cylinder 12. When the iron filings on the surface of the drum 14 rotate to a suitable position, and the influence of the magnetic cylinder 12 on the iron filings is minimal, the iron filings are scattered to the other side of the ramp 8 and discharged from the discharge port 9 on the other side. The scraper 16 is supported by the spring 17, causing the sliding column 15 to slide within the outer casing 1. The scraper 16 adheres to the surface of the drum 14, effectively blocking and scraping away the scattered iron filings. In this patent… Iron filings in scrap copper are attracted by a magnetic cylinder. Under the attraction of the magnetic cylinder, the iron filings rotate with the drum. When the iron filings rotate to the scraper, the iron filings on the outer wall of the drum are pushed by the scraper towards the discharge port of the scrap copper. Due to the action of the magnetic cylinder, the iron filings are continuously attracted and accumulated on the surface of the drum. As the scraper removes them, the iron filings at the bottom of the drum will accumulate more and more. The increased thickness of the iron filings will reduce the adsorption efficiency of iron filings in the pile of scrap copper, resulting in iron filings mixed in with the scrap copper. Furthermore, as the thickness of the iron filings increases, some of the iron filings are easily pushed by the scraper to the scrap copper discharge port and remixed with the scrap copper.

[0004] The main objective of this invention is to provide a magnetic separation device for waste copper impurities, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a magnetic separation device for waste copper impurities, comprising: The machine casing has a material distribution chamber inside; the top and bottom of the machine casing are respectively provided with a material inlet and a material outlet communicating with the material distribution chamber; The magnetic separator assembly includes two sets of transmission components spaced apart within a material distribution chamber and a drive component located outside the casing. A material discharge chamber is formed between the two sets of transmission components. Adsorption components are spaced apart on the transmission components. The two ends of the material discharge chamber are connected to a feed inlet and a discharge outlet, respectively. A magnetic suction component is located inside the transmission component near the material discharge chamber. The magnetic suction component contacts and engages with the adsorption component. The magnetic suction component extends from the material discharge chamber along both ends of the transmission components and forms a chip removal area on the opposite side of the material discharge chamber. The drive component is connected to the transmission components. A chip guide plate is inclinedly arranged within the material distribution chamber, located in the chip removal area. The end of the chip guide plate contacts and connects to the end face of the transmission component. A chip discharge port is located at the bottom end of the chip guide plate on the casing.

[0006] As a further improvement of this utility model, the transmission component includes a transmission wheel rotatably mounted on the housing and two sets of transmission belts mounted on the transmission wheel; a material discharge chamber is formed between the two sets of transmission belts at intervals.

[0007] As a further improvement of this utility model, the driving component includes a drive motor mounted on the housing and a drive gear connected to the drive motor; the transmission wheel is provided with a first driven gear and a second driven gear meshing with each other; the drive gear meshes with the first driven gear; the driving component rotates under the action of external force, thereby driving the two sets of transmission belts to move towards the feed inlet.

[0008] As a further improvement of this utility model, the adsorption element includes adsorption plates spaced apart on the transmission belt; the end face of the adsorption plate is flush with the end face of the transmission belt.

[0009] As a further improvement of this utility model, the magnetic suction component includes a magnetic suction strip installed inside the housing; the magnetic suction strip uses neodymium magnets; the magnetic suction strip includes a vertical section near the material discharge chamber and an arc-shaped section located on the transmission wheel side.

[0011] As a further improvement of this utility model, the end of the chip guide plate is provided with a cleaning brush; the cleaning brush is in contact with the transmission belt.

[0012] The beneficial effects of this utility model are reflected in: By setting a discharge chamber inside the casing to guide the scrap copper downwards along the discharge chamber, and driven by the drive component, the two sets of transmission components move upwards toward the feed inlet. The movement direction of the two sets of transmission components is opposite to the movement direction of the scrap copper, which can increase the contact time between the adsorption component, the magnetic component and the scrap copper, thereby improving the adsorption efficiency of the adsorption component for iron filings in the scrap copper. The adsorption component carries the iron filings and moves with the transmission component to the chip removal area, loses the magnetic attraction and falls onto the chip guide plate, and is discharged along the chip discharge port. The scrap copper after impurity removal is discharged along the discharge port. By performing magnetic attraction and demagnetization operations on the iron filings in the scrap copper, the iron filings are separated from the scrap copper, thus preventing the separated iron filings from mixing with the scrap copper again.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0015] In one embodiment, see Figure 1 ,3 The present invention relates to a magnetic separation device for waste copper impurities, comprising a housing 1 and a magnetic separation component.

[0016] The casing 1 has a material distribution chamber 2 inside, and the top and bottom of the casing 1 are respectively provided with a feed inlet 3 and a discharge outlet 4 communicating with the material distribution chamber 2. The magnetic separation component includes two sets of transmission components 5 spaced apart in the material distribution chamber 2 and a drive component 6 located outside the casing 1. A dropping chamber 7 is formed between the two sets of transmission components 5. Adsorption components 8 are spaced apart on the transmission components 5. The two ends of the dropping chamber 7 are respectively connected to the feed inlet 3 and the discharge outlet 4. A magnetic suction component 9 is provided in the interior of the transmission component 5 near the dropping chamber 7. The magnetic suction component 9 contacts and cooperates with the adsorption component 8. The magnetic suction component 9 extends from the dropping chamber 7 along both ends of the transmission component 5 and forms a chip removal area 10 on the opposite side of the dropping chamber 7. The drive component 6 is connected to the transmission component 5. A chip guide plate 11 located in the chip removal area 10 is inclinedly provided in the material distribution chamber 2. The end of the chip guide plate 11 contacts and connects with the end face of the transmission component 5. A chip discharge outlet 12 located at the bottom end of the chip guide plate 11 is provided on the casing 1.

[0017] Preferably, the housing 1 is a hollow rectangular body, and a support frame 13 is provided at the bottom of the housing 1. The hollow interior of the housing 1 forms a material distribution chamber 2.

[0018] Further, see Figure 3 , 4 The transmission component 5 includes a transmission wheel 501 rotatably mounted on the housing 1 and two sets of transmission belts 502 mounted on the transmission wheel 501. The two sets of transmission belts 502 are spaced apart to form a material discharge chamber 7.

[0019] Preferably, the housing 1 is provided with mounting holes, and bearings are provided in the mounting holes. The inner ring of the bearings is provided with rotating shafts 503. There are four sets of rotating shafts 503. Four sets of transmission wheels 501 are provided and are installed on the rotating shafts 503 in pairs. A set of transmission belts 502 is connected to two sets of transmission wheels 501.

[0020] Further, see Figure 2 , 3 The driving component 6 includes a drive motor 601 mounted on the housing 1 and a drive gear 602 connected to the drive motor 601. The transmission wheel 501 is provided with a first driven gear 603 and a second driven gear 604 meshing with each other. The drive gear 602 meshes with the first driven gear 603. The driving component 6 rotates under the action of external force, thereby driving the two sets of transmission belts 502 to move towards the feed port 3.

[0021] Preferably, the drive motor 601 adopts an existing structure. The drive motor 601 is bolted to the housing 1. The first driven gear 603 and the second driven gear 604 are respectively mounted on the rotating shaft 503 connected to the two sets of transmission belts 502. The drive gear 602, the first driven gear 603, and the second driven gear 604 are provided with protective covers 14. The drive motor 601 is connected to an external power supply through wires and is equipped with a switch. After the drive motor 601 is powered on and rotates counterclockwise, the drive gear 602 rotates and drives the first driven gear 603 to rotate clockwise, thereby driving the set of transmission belts 502 connected to the first driven gear 603 to move upward toward the feed inlet 3. The first driven gear 603 meshes with the second driven gear 604, driving the second driven gear 604 to rotate counterclockwise, thereby driving the transmission belt 502 meshing with the second driven gear 604 to move upward toward the feed inlet 3.

[0022] Further, see Figure 4 The adsorption component 8 includes adsorption plates spaced apart on the transmission belt 502, with the end face of the adsorption plate flush with the end face of the transmission belt 502.

[0023] Preferably, the transmission belt 502 has a groove, the adsorption plate is located in the groove, the adsorption plate has a connecting screw hole, and the side of the transmission belt 502 away from the groove has a fixing plate with a through hole. A screw is used to pass through the through hole and connect to the connecting screw hole, thereby connecting the adsorption plate and the transmission belt 502. The adsorption plate, the fixing plate, and the screw are all made of metal iron.

[0024] Further, see Figure 3 The magnetic suction component 9 includes a magnetic suction strip installed inside the housing 1. The magnetic suction strip uses neodymium magnets and includes a vertical section 901 on the side adjacent to the material discharge chamber 7 and an arc-shaped section 902 on the side of the transmission wheel 501.

[0025] Preferably, two sets of transmission wheels 501 are spaced apart on each set of rotating shafts 503, thereby forming a space between the two sets of transmission wheels 501 for the installation of magnetic strips. When installing magnetic strips, support rods 15 are bolted to the housing 1. Support rods 15 are provided with locking studs 16 that rotate upwards. Magnetic strips are provided with screw holes. By connecting the locking studs 16 with the screw holes, magnetic strips can be installed inside the housing 1. The outer side of the magnetic strip is in contact with the inner side of the transmission belt 502.

[0026] In the above setup, the crushed scrap copper enters from the feed inlet 3 and moves down along the discharge chamber 7. During the downward movement of the scrap copper, the drive motor 601 rotates and drives the transmission belt 502 to move upward toward the feed inlet 3. The direction of movement of the transmission belt 502 is opposite to the direction of the scrap copper's fall. The neodymium magnet transmits the magnetic force to the adsorption plate through the fixed plate. The adsorption plate adsorbs the iron filings in the scrap copper. The iron filings move upward with the transmission belt 502 and move to the vicinity of the chip guide plate 11.

[0027] Further, see Figure 3 Inside the housing 1, baffle rods 17 are arranged alternately from top to bottom within the material discharge chamber 7.

[0028] Preferably, the baffle rod 17 is a cylindrical rod, with both ends of the baffle rod 17 welded to the inner wall of the housing 1. After the crushed waste copper enters the discharge chamber 7, the baffle rod 17 blocks the discharge direction of the waste copper, and the waste copper is thrown and dispersed towards the transmission belt 502, so that the iron filings mixed in the waste copper can fully contact the adsorption plate, thereby improving the collection efficiency of iron filings in the waste copper.

[0029] Further, see Figure 3 The chip guide plate 11 is provided with a cleaning brush 18 at its end, and the cleaning brush 18 is in contact with the transmission belt 502.

[0030] Preferably, the chip guide plate 11 is welded to the inner wall of the housing 1, and the plane of the end of the chip guide plate 11 near the transmission belt 502 is higher than the end of the chip guide plate 11 connected to the housing 1.

[0031] Preferably, discharge pipes 19 are provided at the four discharge ports.

[0032] Preferably, the top of the housing 1 is provided with a feed hopper 20 that communicates with the feed inlet 3, and the two sides of the transmission belt 502 are fitted with the inner wall of the housing 1 with a clearance.

[0033] In the above configuration, as the transmission belt 502 drives the adsorption plate to move upward, it adsorbs the iron filings in the waste copper and drives them to the distribution chamber 2 on the side away from the discharge chamber 7. As the transmission belt 502 moves, the adsorption plate is separated from the magnetic strip and reaches the chip removal area 10. At this time, the iron filings on the adsorption plate are no longer affected by the magnetic strip and begin to fall onto the chip guide plate 11. The cleaning brush 18 cleans the iron filings on the magnetic strip again, so that the iron filings fall onto the chip guide plate 11 and are discharged along the chip discharge port 12.

[0034] In this embodiment, the crushed scrap copper enters from the feed inlet 3 and falls down along the discharge chamber 7. The size of the feed inlet 3 is smaller than the size of the discharge chamber 7. A guide plate 21 can be provided on the top of the housing 1 so that the scrap copper enters the discharge chamber 7. After the scrap copper enters the discharge chamber 7, the drive motor 601 drives the transmission belt 502 to move upward toward the feed inlet 3, so that the transmission belt 502 moves in the opposite direction to the scrap copper. The adsorption plate on the transmission belt 502 adsorbs the iron filings in the scrap copper and transfers them to the chip removal area 10. After the iron filings lose their magnetic adsorption in the chip removal area 10, they fall onto the chip guide plate 11 and are discharged along the chip discharge port 12. The scrap copper with the iron filings removed is discharged from the discharge port 4.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
