[0035] Embodiment

[0036] Please refer to Figure 1-7, the present invention provides a technical solution: a magnetic substance recovery device for solid waste treatment, including a frame 1. On one side of the top of the frame 1, a feeding bin 2 for feeding solid waste is fixed. The feeding bin 2 takes into account the smooth addition of materials. A screen 11 is fixed to the inner wall of the feeding bin 2. The function of the screen 11 is to preliminarily screen the added solid waste, remove large impurities, ensure uniform particle size of the materials, facilitate subsequent processing, and at the same time control the feeding flow rate to avoid material accumulation or blockage. Inside the frame 1, a first rotating roller 12, a magnetic roller 14, and a second rotating roller 15 are respectively rotated. The number of the second rotating rollers 15 is two. A second conveyor belt 16 located below the feeding bin 2 is sleeved on the outside of the two second rotating rollers 15. A first conveyor belt 13 located on one side of the top of the discharge end of the second conveyor belt 16 is sleeved on the outside of the first rotating roller 12 and the magnetic roller 14. The first rotating roller 12, the magnetic roller 14, and the second rotating roller 15 are connected to the inner wall of the frame 1 through bearings to ensure smooth and stable rotation. The magnetic roller 14 is internally provided with a strong magnetic field. When the materials pass through, the magnetic particles therein will be effectively adsorbed to the surface of the roller or the conveyor belt.

[0037] A motor 6 is installed on one side of the frame 1. The motor 6 can be a variable-frequency motor to adjust the speed according to needs, thereby controlling the conveying speed and processing efficiency of the materials. When the motor 6 is started, the magnetic roller 14 will also rotate accordingly, generating a strong magnetic field for adsorbing the magnetic particles in the materials. Two first belt pulleys 7 are fixed to the output shaft end of the motor 6. One of the first belt pulleys 7 is connected to a second belt pulley 8 through a belt, and the other first belt pulley 7 is connected to a third belt pulley 9 through a belt. The rotational power of the motor 6 is transmitted to the second rotating roller 15 through the belt pulleys and belts, driving its rotation, and then driving the second conveyor belt 16 to move to realize the conveying of the materials.

[0038] One end of the axis of the magnetic roller 14 is connected to one end of the axis of the second belt pulley 8, and one end of the axis of one of the second rotating rollers 15 is connected to one end of the axis of the third belt pulley 9. A protective cover is provided outside the first belt pulley 7, the second belt pulley 8, and the third belt pulley 9. A vibration motor 10 is fixed to one side of the feeding bin 2. A first discharge port for discharging non-magnetic substances is opened at the bottom of the frame 1, and a second discharge port for discharging magnetic substances is opened on one side of the frame 1. When the materials are processed by the magnetic roller 14, the non-magnetic substances will directly be discharged from the first discharge port and enter the next processing link or the collection container, making the discharge of non-magnetic substances more convenient and efficient.

[0039] On one side of the frame 1, there is a scraper 4 slidably connected to the outside of the first conveyor belt 13. On one side of the frame 1, there is also a second discharge port for discharging magnetic substances. When the magnetic roller 14 adsorbs magnetic particles, the magnetic substances are scraped off from the surface of the roller or the conveyor belt by the scraper 4 and collected in the collection container at the second discharge port. In this way, the magnetic substances are effectively recycled and utilized. On one side of the scraper 4, there is a connection assembly 5. On one side of the feeding bin 2, there is a feeding assembly 3 for adjusting the feeding speed of solid waste treatment;

[0040] The feeding assembly 3 includes a connecting plate 31. On one side of the top of the connecting plate 31, there is a baffle 36. On the surface of the baffle 36, there are scale lines 35. The scale lines 35 on the surface of the baffle 36 are not only used to indicate the position of the baffle 36, but also enable the operator to directly adjust the feeding speed according to the scale lines 35 without relying on additional measuring tools or empirical judgments;

[0041] On one side of the frame 1, there is a screw rod 32 rotatably connected. The outside of the screw rod 32 is threadedly connected to one side of the connecting plate 31. In order to ensure that the screw rod 32 and the connecting plate 31 can maintain a fixed position, a self-locking nut is installed at the end of the screw rod 32 and cooperates with the connecting plate 31. When the handwheel 33 stops rotating, the self-locking nut will lock the screw rod 32 to prevent it from rotating due to gravity or other external forces, so as to maintain the fixed positions of the connecting plate 31 and the baffle 36. One end of the screw rod 32 is fixed with a handwheel 33. On one side of the frame 1, there is a sliding column 34 fixedly passing through one side of the connecting plate 31. One end of the sliding column 34 is fixed with a limiting block. The outside of the baffle 36 passes through the frame 1 and is seamlessly inserted into one side of the feeding bin 2; when the baffle 36 moves to the left, the feeding speed of the feeding bin 2 is reduced, and when the baffle 36 moves to the right, the feeding speed of the feeding bin 2 is increased.

[0042] The connection assembly 5 includes a fixing frame 51. Inside the fixing frame 51, there are a limiting groove 54 and a sliding groove 59 respectively. Inside the sliding groove 59, there is a sliding plate 53 slidably connected. Inside the limiting groove 54, there is a limiting rod 57 inserted. When the sliding plate 53 is pulled to one side, the locking rod 55 leaves the locking groove 56. At this time, the scraper 4 can be taken off by pulling it obliquely upward. The top of the limiting rod 57 is fixed with a fixing plate 58, and the top of the fixing plate 58 is fixed to the bottom side of the scraper 4. The outside of the fixing frame 51 is fixed to one side of the frame 1. Between one side of the sliding plate 53 and the inside of the sliding groove 59, there is a spring 52 connected. One side of the sliding plate 53 is fixed with a locking rod 55. On one side of the limiting rod 57, there is a locking groove 56. When the locking rod 55 is inserted into the inside of the locking groove 56, the scraper 4 is in the installed state, and when the locking rod 55 leaves the inside of the locking groove 56, the scraper 4 is in the disassembled state. When installing a new scraper 4, only need to insert the limiting rod 57 into the inside of the limiting groove 54, make the locking rod 55 inserted into the inside of the locking groove 56, and the spring 52 presses the locking rod 55 to ensure the stable operation of the scraper 4.

[0043] Working principle: When magnetic substances need to be separated from the solid waste materials to be processed, only need to feed the solid waste materials into the feeding bin 2 through the top feeding port. The built-in screen 11 preliminarily screens the materials, disperses large pieces of materials and controls the feeding flow rate. The vibration motor 10 vibrates to promote the flow of materials and prevent blockage. At the same time, it assists the screen 11 to separate impurities, so that large pieces of solid waste are blocked at the top of the screen 11. Workers crush the waste blocked at the top of the screen 11 again and add it to the inner side of the feeding bin 2;

[0044] The output shaft of the control motor 6 drives two first belt pulleys 7 to rotate. The two first belt pulleys 7 respectively drive the second belt pulley 8 and the third belt pulley 9 to rotate through belts. The second belt pulley 8 and the third belt pulley 9 respectively drive the second rotating roller 15 and the magnetic roller 14. Driven by the two second rotating rollers 15, the solid waste is conveyed from the feeding bin 2 to the magnetic roller 14. The non-magnetic substances directly fall to the first discharge port at the bottom of the frame 1 and are discharged. Driven by the first rotating roller 12 and the magnetic roller 14, the magnetic substances are adsorbed and conveyed upward. The strong magnetic field of the magnetic roller 14 adsorbs the magnetic particles to the belt surface. The scraper 4 scrapes off the magnetic substances adsorbed on the belt surface of the first conveyor belt 13 and discharges them through the second discharge port on the side of the frame 1;

[0045] When the contact part between the scraper 4 and the first conveyor belt 13 is worn and the scraper 4 needs to be replaced, only need to pull the slide plate 53 to one side, so that the locking rod 55 leaves the locking groove 56. At this time, pull the scraper 4 obliquely upward to remove it. When a new scraper 4 needs to be installed, only need to insert the limiting rod 57 into the inner side of the limiting groove 54, so that the locking rod 55 is inserted into the inner side of the locking groove 56, and the spring 52 presses the locking rod 55 to ensure the stable operation of the scraper 4;

[0046] When it is necessary to adjust the feeding speed of the solid waste materials, only need to rotate the handwheel 33. The handwheel 33 drives the lead screw 32, drives the connecting plate 31 to move linearly along the sliding column 34. The connecting plate 31 moves and inserts into the inside of the feeding bin 2. The left side of the connecting plate 31 moves to reduce the area of the feeding port, thereby reducing the feeding speed. The right side of the connecting plate 31 moves to increase the feeding port and improve the feeding speed. The scale line 35 provides a reference for the insertion distance of the connecting plate 31.

[0047] In summary, through the preliminary screening of the materials by the screen 11, large pieces of materials can be dispersed and the feeding flow rate can be controlled, so that the materials enter the subsequent treatment links more evenly. The motor 6 drives the first belt pulley 7, the second belt pulley 8 and the third belt pulley 9 to rotate, and then drives the second rotating roller 15 and the magnetic roller 14, realizing the continuous and stable conveying of the materials. The strong magnetic field of the magnetic roller 14 can effectively adsorb the magnetic particles to the belt surface, while the scraper 4 is responsible for scraping off the magnetic substances adsorbed on the first conveyor belt 13 and discharging them through the second discharge port, realizing the effective recovery of the magnetic substances, avoiding the residue and accumulation of the magnetic substances in the equipment, and improving the utilization rate of resources.

[0048] By pulling the slide plate 53 to one side, the locking rod 55 is disengaged from the locking groove 56, and then the scraper 4 can be easily removed by pulling it obliquely upward, simplifying the replacement process and reducing the time and labor required for replacing the scraper 4. When installing a new scraper 4, the limiting rod 57 is inserted into the limiting groove 54, and the locking rod 55 is inserted into the locking groove 56, and the locking rod 55 is pressed by the spring 52, ensuring the stability of the scraper 4 after installation.

[0049] By rotating the handwheel 33 to drive the lead screw 32, the connecting plate 31 is driven to move linearly along the sliding column 34, and the depth of insertion of the connecting plate 31 into the feeding bin 2 can be controlled, thereby flexibly adjusting the area of the material discharge port, enabling the material discharge speed to be adjusted in real time according to actual requirements, meeting the material discharge requirements under different working conditions. The setting of the scale line 35 provides an intuitive reference for the insertion distance of the connecting plate 31, enabling the operator to accurately understand the current material discharge port area and the corresponding material discharge speed, improving the accuracy of adjusting the material discharge speed.
