Description
Technical Field
[0001] The present invention relates to the technical field of eddy current separators, and particularly to a combined eddy current separator. Background Art
[0002] An eddy current separator is an effective method for recovering non-ferrous metals from solid waste. That is, when materials containing non-magnetic metals (such as copper and aluminum) pass through an alternating magnetic field at a certain speed, an induced eddy current will be generated at this time, generating a separation thrust with a certain angle with the direction of the magnetic field. They leave at a certain speed, and the movement trajectory is different from that of non-ferrous metals, achieving the purpose of separation. The existing eddy current separators can screen non-magnetic materials such as copper and aluminum, but cannot collect metals such as ferroalloys, iron, cobalt, and nickel. For this reason, we propose a combined eddy current separator. Summary of the Invention

Detailed implementation manners
[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0025] Referring to Figures 1 to 8 , the present invention provides a technical solution: a combined eddy current separator, including a mounting frame 16, and a plurality of support legs 20 are provided at the bottom of the mounting frame 16, and the support legs 20 are supported on the ground.
[0026] An eddy current separation device is provided at the top of the mounting frame 16. As Figure 1 and Figure 4 shown, the eddy current separation device includes a second conveyor belt 12 located above the mounting frame 16. A magnetic roller 13 is provided inside one end of the second conveyor belt 12. The magnetic roller 13 needs to be arranged at the end of the mounting frame 16. Both ends of the magnetic roller 13 are rotatably connected to the mounting frame 16, and one end of the magnetic roller 13 is driven to rotate by a driving mechanism. The driving mechanism includes a first motor 22 provided below the end of the mounting frame 16. Pulley wheels are provided on the rotating shaft of the first motor 22 and one end of the magnetic roller 13, and the two pulley wheels are connected by a belt;
[0027] At the other end of the second conveyor belt 12, a first support roller 26 is provided inside. The first support roller 26 and the magnetic roller 13 support the second conveyor belt 12 at the same time, keeping the second conveyor belt 12 in a taut state. During installation, the two ends of the first support roller 26 are rotatably installed inside the first adjustment seat 24. Chutes (not labeled in the figure) are provided at both the upper and lower ends of the first adjustment seat 24. The first adjustment seat 24 is respectively placed inside the rectangular frame 25. Bar-shaped limit blocks 37 are provided on the upper and lower sides inside the rectangular frame 25. The bar-shaped limit blocks 37 are movably placed inside the chutes, and the rectangular frame 25 is installed on the installation frame 16. In this way, the first adjustment seat 24 can slide reciprocally along the bar-shaped limit blocks 37, so as to adjust the distance between the first support roller 26 and the magnetic roller 13, and the tension of the second conveyor belt 12 can be adjusted.
[0028] On one side of each of the first adjustment seats 24, a first adjustment screw 23 is provided. The first adjustment screw 23 is movably placed inside the rectangular frame 25, and the first adjustment screw 23 is fastened to the rectangular frame 25 through a fastener. Here, the fastener is a nut provided on the first adjustment screw 23. Therefore, by adjusting the nut, the first adjustment screw 23 can be driven to expand and contract inside the rectangular frame 25, thereby pulling the first support roller 26 to move.
[0029] During actual operation, the material to be screened is conveyed from one end of the second conveyor belt 12 towards the magnetic roller 13. When the material passes through the magnetic roller 13, the non-ferrous metals (such as aluminum, copper, zinc, silver, etc.) in the material can jump up. In order to collect the jumping non-ferrous metals, a material distribution chute 14 is provided obliquely downward at one end of the second conveyor belt 12 close to the magnetic roller 13. Both sides of the material distribution chute 14 are connected to the installation frame 16 through fixing frames, so the non-ferrous metals will fall on the material distribution chute 14. There is a discharge gap between the top of the material distribution chute 14 and the second conveyor belt 12, which can allow the remaining material to fall from the end of the second conveyor belt 12. An inclined downward first guide chute 15 is provided below the discharge gap, and the first guide chute 15 is installed and connected to the support leg 20.
[0030] Furthermore, a bar-shaped support frame 11 is provided above the eddy current separation device. The bar-shaped support frame 11 is connected to the installation frame 16 through a frame body, as Figure 1 and Figure 6As shown in the figure, the frame body includes two parallel U-shaped machine frames 8 with their openings facing downward, and the strip-shaped support frame 11 is located inside the U-shaped machine frames 8. The two U-shaped machine frames 8 are respectively installed on both sides of the top of the installation frame 16. The tops of the two U-shaped machine frames 8 are connected by a connecting beam 6. A hydraulic cylinder 7 is installed in the middle of the connecting beam 6. The bottom of the hydraulic cylinder 7 is connected to a U-shaped connecting frame 19 with its opening facing downward. The two ends of the U-shaped connecting frame 19 are respectively connected to both sides of the top of the strip-shaped support frame 11. On both sides inside each U-shaped machine frame 8, there are respectively provided first guide rails 21. Each first guide rail 21 is connected to the strip-shaped support frame 11 through a slider. Therefore, when the hydraulic cylinder 7 expands and contracts, it can drive the strip-shaped support frame 11 to move stably up and down along the first guide rails 21;
[0031] A strip-shaped magnetic adsorption device is provided inside the strip-shaped support frame 11. The magnetic adsorption device and one end of the strip-shaped support frame 11 extend outside the eddy current separation device. As Figure 6 and Figure 7 shown, the strip-shaped magnetic adsorption device includes a strip-shaped box 36 installed inside the strip-shaped support frame 11. At the bottom inside the strip-shaped box 36, there is a strong magnet or an electromagnet. One end of the strip-shaped box 36 extends outside the eddy current separation device. The bottom of the strip-shaped box 36 is a flat surface. The suction force generated by the strong magnet or the electromagnet can make the flat surface at the bottom of the strip-shaped box 36 adsorb metals such as ferroalloys, iron, cobalt, and nickel;
[0032] At both ends below the strip-shaped support frame 11, there are respectively rotatably provided driving rollers 34. One of the driving rollers 34 is driven to rotate by a driving device. Here, the driving device includes a second motor 35 provided at one end of the strip-shaped support frame 11. Sprockets are provided on the rotating shafts of the second motor 35 and the driving roller 34. The two sprockets are connected by a chain. A first conveyor belt 9 is connected between the two driving rollers 34, and the strip-shaped magnetic adsorption device is located inside the first conveyor belt 9;
[0033] At one end of the top of the strip-shaped support frame 11, there is rotatably provided a second support roller 33. At the other end of the top of the strip-shaped support frame 11, there is a tensioning roller 29. Both the second support roller 33 and the tensioning roller 29 are located inside the first conveyor belt 9. The two ends of the tensioning roller 29 are respectively rotatably connected to sliding seats 31. The sliding seats 31 are slidably arranged on the second guide rails 30. The second guide rails 30 are installed on the top of the strip-shaped support frame 11. As Figure 7 shown, at one end of each sliding seat 31, there is provided a second adjusting screw 28. One end of the second adjusting screw 28 is movably placed inside a second adjusting seat 32, and the second adjusting seat 32 is installed on the strip-shaped support frame 11. The second adjusting screw 28 and the second adjusting seat 32 are fastened by a fastening member. Here, the fastening member is a nut provided on the second adjusting screw 28. By adjusting the nut, the telescopic movement of the second adjusting screw 28 inside the second adjusting seat 32 can be adjusted, so as to adjust the distance between the tensioning roller 29 and the driving roller 34, and thus make the tensioning roller 29 tighten the first conveyor belt 9.
[0034] Further, as Figure 1 shown, an inclined upward shaking trough 5 is provided above one end of the second conveyor belt 12 away from the magnetic roller 13. At least two connecting seats 27 are respectively provided on both sides of the shaking trough 5. The bottoms of the connecting seats 27 are all installed on the top of the support frame 1 through the support springs 18. The bottom of the support frame 1 is fixed on the installation frame 16. A vibration motor 10 is provided at the bottom of the shaking trough 5. During use, the material to be screened passes through the shaking trough 5. Since the shaking trough 5 is driven by the vibration motor 10 to shake, the material passing through the shaking trough 5 is scattered, so that the material falling on the second conveyor belt 12 can be evenly spread out, avoiding accumulation on the second conveyor belt 12;
[0035] Immediately afterwards, a material equalizing hopper 3 is provided at one end of the installation frame 16 away from the shaking trough 5. A hoist 4 is provided below the material equalizing hopper 3. The hoist 4 is inclined upward and its top is placed above the top of the shaking trough 5. Both sides of the hoist 4 are respectively connected to the installation frame 16 through brackets 2. As Figure 1 and Figure 2 shown, the material equalizing hopper 3 is arranged at a low position, which is convenient for manual pouring of the material to be screened into the material equalizing hopper 3. Then the material falls on the hoist 4, and the hoist 4 drives the material to be sent into the shaking trough 5.
[0036] Based on the above embodiments, the specific working process is as follows: Pour the material to be screened into the material equalizing hopper 3, and the hoist 4 drives the material to be sent into the shaking trough 5. The material passing through the shaking trough 5 is scattered, and then the material evenly falls on the second conveyor belt 12. As the second conveyor belt 12 gradually advances forward, when the material passes under the first conveyor belt 9, since the bottom surface of the strip-shaped box 36 in the first conveyor belt 9 continuously generates electromagnetic force, metals such as ferroalloy, iron, cobalt, and nickel in the material will be adsorbed on the first conveyor belt 9, and these metals will move with the first conveyor belt 9 to the outside of the second conveyor belt 12;
[0037] It should be noted that although one end of the strip-shaped box 36 extends outside the second conveyor belt 12, as Figure 6 and Figure 7 shown, there is still a certain distance between the strip-shaped box 36 and the driving roller 34. Therefore, the magnetic force at the bottom of the strip-shaped box 36 disappears before reaching the end of the strip-shaped support frame 11. So when the metal moves with the first conveyor belt 9 to the end of the strip-shaped support frame 11, it falls, thereby collecting metals such as ferroalloy, iron, cobalt, and nickel. As Figure 2 shown, a second material guiding trough 17 is provided on one side of the installation frame 16 and inclines downward. The second material guiding trough 17 is located under the first conveyor belt 9. A container can be placed below the second material guiding trough 17 for collection;
[0038] When the materials first screened by the first conveyor belt 9 move to the magnetic roller 13 along with the second conveyor belt 12, the non-ferrous metals in the materials can jump up and fall on the material distribution chute 14, and the remaining materials fall from the end of the second conveyor belt 12 and finally fall from the first material guide chute 15, and containers can be placed below the first material guide chute 15 and the material distribution chute 14 respectively for collection.
[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
