Description

Technical Field

[0001] This invention relates to the field of waste steel ball recycling technology for ball mills, specifically a waste steel ball recycling system for ball mills. Background Technology

[0002] Ball mills are a commonly used grinding equipment in industries such as mining, cement, building materials, and chemicals. They use steel balls as grinding media to crush and grind materials. During the use of a ball mill, the steel balls gradually shrink due to wear and impact, eventually forming waste steel balls.

[0003] Traditional waste steel ball processing involves transporting the waste steel balls to a centralized processing area. However, these waste steel balls are usually mixed with ground materials (such as iron minerals), and the accumulated iron minerals amount to a considerable quantity. To save resources and costs, it is necessary to screen and recycle the iron minerals and waste steel balls. However, the quantity of waste steel balls is particularly large, and manual screening requires a significant investment of manpower, resulting in a slow recycling rate and high costs. When using screening machinery, the large input of waste steel balls can easily cause blockages, leading to slow processing, poor screening effect, and an inability to completely separate the waste steel balls from the iron minerals. Therefore, a waste steel ball recycling system for ball mills is needed. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide a waste steel ball recycling system for ball mills, which splits the material into two parts for processing, and the two parts complement each other, thereby improving screening efficiency and achieving a high iron ore recovery rate.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a waste steel ball recycling system for a ball mill, comprising a feeding module, a conveying module, a screening module, a storage box, and a recycling box. A mixture of waste steel balls and iron ore is fed from the feeding module to the conveying module for conveying. After preliminary screening by the conveying module, the mixture enters the screening module for complete screening. The waste steel balls are stored in the storage box, and the iron ore is recycled in the recycling box.

[0006] In some embodiments, the feeding module includes a first support frame, on which a feeding hopper is mounted. Two spring hooks are provided on each side of the feeding hopper, and the four spring hooks are connected to a discharge trough. A connection port is provided on the discharge trough, and the connection port is rotatably connected to the feeding hopper. A vibrator is mounted on the feeding hopper, and a spiral auger is provided near the connection port of the feeding hopper.

[0007] In some embodiments, a rotating plate is rotatably connected inside the discharge trough, and a handle is slidably connected to the end of the rotating plate. A plurality of support plates are provided at one end of the discharge trough near the conveying module, and the support plates cooperate with the handle to fix the rotating plate.

[0008] In some embodiments, the conveying module includes a second support frame and a motor. A conveyor belt is mounted on the second support frame. The conveyor belt includes a drive roller and a driven roller. The motor is connected to the drive roller of the conveyor belt. The driven roller is a magnetic roller. Baffles are provided on both sides of the conveyor belt. The second support frame is connected to the screening module. The surface of the conveyor belt is provided with multiple grooves.

[0009] In some embodiments, the screening module includes four spring connecting rods, which are connected together to a first screen. A second screen is slidably connected to the first screen. A baffle is connected to the end of the second screen near the feeding module via a torsion spring. A guide plate is installed on the first screen, located between the first screen and the second screen. A separation plate is bolted to the end of the second screen away from the baffle. The separation plate is connected to the conveying module. A cleaning brush is provided on the end of the guide plate, and the cleaning brush contacts the separation plate.

[0010] In some embodiments, the first screen includes a first screen frame, with grooves on both sides of the first screen frame and a first mounting plate at the end of the first screen frame near the separating plate. The second screen includes a second screen frame, with a sliding rod at the end of the second screen frame near the baffle, the sliding rod being slidably connected to the grooves. Protective plates are provided on both sides of the second screen frame, and a second mounting plate is provided at the end of the second screen frame away from the baffle. A vibration motor is mounted on the side of the second screen frame.

[0011] In some embodiments, the mesh size of the second wire frame is larger than that of the first wire frame, and the mesh diameter of the second wire frame is larger than that of the scrap steel ball.

[0012] In some embodiments, the baffle includes a connecting shaft, with a clapper fixedly connected to the upper end of the connecting shaft and a ramming plate fixedly connected to the lower end.

[0013] In some embodiments, the diameter of the separating plate is smaller than the diameter of the guide plate, and limit plates are provided on both sides of the separating plate. The separating plate is formed by connecting two inclined straight plates. An arc-shaped part is provided at one end of the guide plate near the separating plate. Two guide strips are provided on the guide plate, and the two guide strips are arranged in a figure-eight shape. The distance between the two guide strips at their closest ends is the same as the length of the impact plate.

[0014] In summary, the present invention has the following beneficial effects:

[0015] I. This invention utilizes the magnetic force of the separating plate of the screening module and the driven roller of the conveying module to initially separate iron minerals and waste steel balls, allowing waste steel balls with a large amount of iron minerals to be adhered to and to be processed separately from waste steel balls without a large amount of iron minerals.

[0016] Second, a baffle is installed, with a clapper inside the baffle blocking waste steel balls with a large amount of iron minerals adhering to them. The vibration caused by the obstruction causes the adhering iron minerals to fall off, achieving a separation effect. At the same time, waste steel balls without a large amount of iron minerals adhering to them are guided by a guide plate to collide with a striking plate. During the collision, not only are their own iron minerals shaken off, but the entire baffle also swings. The clapper inside the swinging baffle knocks the waste steel balls, after the iron minerals have been separated, off the first mesh frame and onto the guide plate. The iron minerals are scraped off by the first mesh frame and shaken off by the impact when in contact with the guide plate, achieving a thorough separation. Finally, all the steel balls slide through the second mesh frame into the recycling bin, while the iron minerals are screened into the storage bin, achieving a thorough separation. The screening effect is strong, improving the recovery efficiency of iron minerals. Attached Figure Description

A plurality of grooves 26 are provided on the surface of the conveyor belt 23.

[0029] In some embodiments, the screening module 3 includes four spring connecting rods 31, which are connected together to a first screen 32. A second screen 33 is slidably connected to the first screen 32. The end of the second screen 33 near the feeding module 1 is connected to a second baffle 36 by a torsion spring. A guide plate 34 is bolted to the first screen 32 and is located between the first screen 32 and the second screen 33. A separation plate 35 is bolted to the end of the second screen 33 away from the second baffle 36. The separation plate 35 is connected to the conveying module 2.

[0030] In some embodiments, the first screen 32 includes a first screen frame 321, with sliding grooves 322 on both sides of the first screen frame 321, and a first mounting plate 323 at the end of the first screen frame 321 near the separating plate 35. The second screen 33 includes a second screen frame 331, with a sliding rod at the end of the second screen frame 331 near the second baffle 36, the sliding rod being slidably connected to the sliding groove 322. Protective plates 332 are provided on both sides of the second screen frame 331, and a second mounting plate 333 is provided at the end of the second screen frame 331 away from the second baffle 36. A vibration motor 38 is mounted on the side of the second screen frame 331.

[0031] In some embodiments, the mesh size of the second mesh frame 331 is larger than that of the first mesh frame 321, and the mesh diameter of the second mesh frame 331 is larger than that of the scrap steel ball.

[0032] In some embodiments, the second baffle 36 includes a connecting shaft 361, with a clapper 362 welded to the upper end and a ramming plate 363 welded to the lower end of the connecting shaft 361.

[0033] In some embodiments, the diameter of the separating plate 35 is smaller than the diameter of the guide plate 34, and the separating plate 35 is provided with limit plates 351 on both sides. The separating plate 35 is formed by connecting two inclined straight plates. The guide plate 34 is provided with an arc-shaped part 341 at one end near the separating plate 35. The guide plate 34 is provided with two guide strips 342, and the two guide strips 342 are arranged in a figure-eight shape. The distance between the two guide strips 342 at their closest ends is the same as the length of the impact plate 363.

[0034] Working principle: During operation, the operator pours the material into the feeding hopper 12. The material is then conveyed from the feeding hopper 12 through the discharge chute 14 to the conveyor belt 23. During the feeding process, the vibrator 15 drives the feeding hopper 12 to vibrate, and the discharge chute 14 also vibrates under the action of the spring hook 13, thereby accelerating the feeding speed. If a blockage occurs in the discharge chute 14, the operator can swing the turntable 16 up and down to allow the material to be conveyed to the conveyor belt 23 more quickly. When the material is conveyed on the conveyor belt 23, the groove 26 helps the scrap steel balls in the material to be conveyed more stably, and the first baffle 25 can also limit the material to prevent it from falling. When the material is conveyed to the driven roller 24, the conveyor belt 23 and the screening module 3 are all tilted. The system is designed to allow scrap steel balls and iron ores to slide smoothly. Influenced by the magnetic force of the driven roller 24, most of the iron ores are affected and fall from the side of the separating plate 35 near the second screen 33. As they pass the second screen 33, they fall onto the guide plate 34, and finally slide from the guide plate 34 to the first screen 32, before falling into the storage box 4. Simultaneously with the iron ores falling from the side of the separating plate 35 near the second screen 33, some scrap steel balls with a significant amount of iron ores adhering to them will also slide down onto the second screen 33 due to the magnetic influence of the iron ores on their surface, impacting the striking plate 362. The striking plate 362, restrained by a torsion spring, effectively blocks the scrap steel balls with a significant amount of iron ores adhering to them, causing the iron ores on the surface of the scrap steel balls with a significant amount of iron ores to be impacted. The steel balls fall onto the guide plate 34, achieving separation. These steel balls, now free of iron ore, are temporarily stored at the impact plate 362. Most of the steel balls without significant iron ore adhesion fall from the side of the separation plate 35 away from the second screen 33. As they fall, they are obstructed by the cleaning brush 37, causing them to slide intermittently down the guide plate 34. Simultaneously, the cleaning brush 37 removes any remaining iron ore adhering to the surface of these steel balls, ensuring complete iron ore recovery. Then, batches of steel balls gain acceleration from the arc-shaped portion 341 of the guide plate 34 and plunge downwards. Guided by the two figure-eight shaped guide strips 342, they impact the impact plate 363, causing the impact plate 363 and the impact plate 362 to collide. The 62 swings around the connecting shaft 361, further vibrating off the iron minerals adhering to its surface. Then, the slapping plate 362 slaps the scrap steel balls temporarily stored on the slapping plate 362. The mesh diameter of the second mesh frame 331 is slightly larger than the diameter of the scrap steel balls, temporarily supporting the scrap steel balls with a large amount of adhering iron minerals, preventing them from falling off the second mesh frame 331. After being slapped by the slapping plate 362, these scrap steel balls fall from the second mesh frame 331 onto the guide plate 34. During this process, the vibration of the mesh of the second mesh frame 331 and the impact of falling onto the guide plate 34 remove the adhering iron minerals. Finally, all the scrap steel balls and the separated iron minerals enter the first mesh frame 321 from the guide plate 34.Scrap steel balls slide down the first mesh frame 321 into the recycling bin 5, while iron ore passes through the first mesh frame 321 into the storage bin 4 for collection, thus completing the complete screening and collection of scrap steel balls and iron ore. Throughout the process, the vibrating motor 38 is in operation, helping to accelerate the movement of the scrap steel balls and iron ore.
