[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0026] like Figures 1 to 6 As shown:

[0027] The prior art in this embodiment has the following problems: The inventors have found the following defects in the prior art: 1. During the long-term stockpiling of slag, plastic waste is easily mixed into the slag pile. The device does not have a mechanism to clean out the waste. This plastic waste may get stuck inside the crushing device during the subsequent crushing process, leading to accidents; 2. During the stockpiling and transportation of slag, soil will adhere to the surface of the slag. The device does not have a corresponding cleaning mechanism for this soil. After long-term operation, soil will accumulate on the surface of the device, reducing the service life of the device and polluting the working environment; 3. The slag contains a large amount of associated pyrite. The device does not separate and recover these minerals, resulting in resource waste.

[0028] Therefore, the inventor provides a mining slag treatment device, including a cleaning device, a recycling device, and a control cabinet. The cleaning device is located above the recycling device, and the control cabinet (not shown in the figure) is located outside the cleaning device and the recycling device and is electrically connected to the cleaning device and the recycling device. The cleaning device also includes a waste cleaning mechanism 1 and a washing mechanism 2. The waste cleaning mechanism 1 is located above the washing mechanism 2 on the left side, and the lower outlet of the waste cleaning mechanism 1 is connected to the left inlet of the washing mechanism 2 through a pipe. The recycling device also includes a crushing roller 3, a conveyor belt device 4, and a magnetic separation mechanism 5. The crushing roller 3 is located below the right outlet of the washing mechanism 2, the conveyor belt device 4 is located below the crushing roller 3, and the magnetic separation mechanism 5 is located above the conveyor belt device 4.

[0029] Using the above method, the slag is poured in from above the waste cleaning mechanism 1. Plastic waste is removed from the slag in the waste cleaning mechanism 1. The cleaned slag falls downward into the washing mechanism 2, where the mud attached to the surface of the slag is washed away. It then falls to the right into the crushing roller 3 to be crushed and refined. After that, it falls onto the conveyor belt device 4 and is conveyed to the right above the magnetic separation roller 21. The magnetic separation roller 21 adsorbs and separates the pyrite particles in the slag. After that, they are collected and recycled. The remaining slag is conveyed to the next processing step to complete the slag processing. Example 2

[0030] like Figures 1 to 6 As shown:

[0031] Furthermore, the garbage cleaning mechanism 1 also includes a housing a6, a mounting plate 7, a rack 8, a gear 9, a drive motor a10, and a cleaning rod 11. The mounting plate 7 is respectively disposed on the left and right sides of the housing a6 and is slidably connected to the housing a6. The rack 8 is respectively disposed on the upper and lower sides of the mounting plate 7 located on the right side. The gear 9 is disposed between the racks 8 and meshes with the upper and lower racks 8. The drive motor a10 is disposed on the right side of the gear 9 and its output end is connected to the gear 9. The cleaning rod 11 is disposed between the mounting plates 7 on the left and right sides of the housing a6.

[0032] Furthermore, cleaning support rods 12 are also provided between the cleaning rods 11;

[0033] In this process, after the slag is poured into the waste cleaning mechanism 1, the drive motor a10 drives the gear 9 to rotate, causing the rack 8 to slide the mounting plate 7 on the box a6. As the slag falls, the cleaning rod 11 and the cleaning support rod 12 repeatedly push the slag apart. The strip-shaped plastic waste in the slag is left on the cleaning rod 11 under the pushing action of the cleaning rod 11. This automatic cleaning of plastic waste in the slag saves time and effort, avoids extra workload, protects the subsequent equipment, and extends the service life of the equipment. Afterward, the pushed-apart slag falls downward through the pipe into the cleaning mechanism 2. Example 3

[0034] like Figures 1 to 6 As shown:

[0035] Furthermore, the cleaning mechanism 2 also includes a housing b13, a drive motor b14, a rotating shaft 15, a cleaning drum 16, a draining drum 17, and a spiral blade 18. The housing b13 is located on the lower right side of the garbage cleaning mechanism 1, the drive motor b14 is located on the left side of the housing b13, the rotating shaft 15 is located at the right output end of the drive motor b14 and is rotatably connected to the housing b13, the cleaning drum 16 with perforations on its surface (not shown in the figure) is located inside the housing b13 and is connected to the rotating shaft 15, the draining drum 17 with perforations on its surface (not shown in the figure) is connected to the right side of the cleaning drum 16 through a section of cone, and the spiral blade 18 is located inside the cleaning drum 16, the cone, and the draining drum 17.

[0036] Furthermore, the housing b13 also includes a washing chamber 19 and a draining chamber 20. The washing chamber 19 is located below the washing roller 16, and an inlet pipe and a drain pipe a26 are provided on the rear side of the washing chamber 19. The draining chamber 20 is located below the cone on the right side of the washing roller 16 and the draining roller 17. The washing roller 16 and the housing b13 are rotatably sealed together, and a drain pipe b27 is provided on the rear side of the draining chamber 20.

[0037] In this process, the slag from the plastic waste removal process enters the washing drum 16 through the left-side pipe. The drive motor b14 drives the rotating shaft 15 to rotate the washing drum 16, the cone, and the draining drum 17. The control cabinet controls the water inlet pipe to add water to the washing chamber 19. As the slag rolls in the washing drum 16, the surface dirt and dust are washed away. Wastewater is discharged through the drain pipe a26. As the washing drum 16 rotates, the slag passes through the spiral blades 18 and enters the draining drum 17 through the cone to drain the water. The drained water is discharged from the draining chamber 20 through the drain pipe b27. The washed material is discharged downward into the crushing roller 3. This process removes the dirt from the surface of the slag, preventing dirt from adhering to the surface of the device during subsequent processing, extending the service life of the device, and avoiding dirt contamination of the working environment of the device. Example 4

[0038] like Figures 1 to 6 As shown:

[0039] Furthermore, the magnetic separation mechanism 5 also includes a magnetic separation roller 21 and a cleaning mechanism, the cleaning mechanism being disposed above the magnetic separation roller 21 and slidably connected to the magnetic separation roller 21;

[0040] Furthermore, the cleaning mechanism also includes a lead screw guide rail 22, a cleaning plate 23, and a recycling box 24. The lead screw guide rail 22 is located above the magnetic separation roller 21, the cleaning plate 23 is located on the slider below the lead screw guide rail 22 and the cleaning plate 23 is slidably connected to the magnetic separation roller 21, and the recycling box 24 is located below the rear side of the magnetic separation roller 21.

[0041] Furthermore, the rear side of the magnetic separator 21, located above the recycling bin 24, is not equipped with a magnetic assembly;

[0042] In this process, the slag, after being washed and drained, is crushed by the crushing roller 3 and falls downwards onto the conveyor belt device 4. It is then conveyed to the right by the conveyor belt device 4. When it reaches the area below the magnetic separation roller 21, the magnetic minerals such as pyrite in the crushed slag are adsorbed and separated by the magnetic separation roller 21. The magnetically separated slag continues to be conveyed to the right to the next process. The minerals accumulated on the surface of the magnetic separation roller 21 can be pushed backwards along the surface of the magnetic separation roller 21 by the lead screw guide 22, which drives the cleaning plate 23 to move backwards. This pushes the minerals on the surface of the magnetic separation roller 21 onto the recovery box 24. The minerals above the recovery box 24 lose their magnetic attraction and fall downwards into the recovery box 24 to complete the recovery. In this way, the magnetic minerals in the slag can be recovered, improving the resource utilization efficiency.

[0043] The working principle of this utility model:

[0044] The slag is poured in from above the waste cleaning mechanism 1. The drive motor a10 drives the gear 9 to rotate, causing the rack 8 to slide the mounting plate 7 on the box a6. As the slag falls, the cleaning rod 11 and the cleaning support rod 12 repeatedly push the slag apart. The strip-shaped plastic waste in the slag is left on the cleaning rod 11 under the pushing action of the cleaning rod 11. This automatically cleans the plastic waste in the slag, saving time and effort, avoiding extra workload, protecting the subsequent equipment, and extending the service life of the equipment.

[0045] The slag from the plastic waste removal process enters the washing drum 16 through the left-side pipe. The drive motor b14 drives the rotating shaft 15 to rotate the washing drum 16, the cone, and the draining drum 17. The control cabinet controls the water inlet pipe to add water to the washing chamber 19. As the slag rolls in the washing drum 16, the surface dirt and dust are washed away. The wastewater is discharged through the drain pipe a26. As the washing drum 16 rotates, the slag passes through the spiral blades 18 and enters the draining drum 17 through the cone to drain the water. The drained water is discharged through the drain pipe b27 in the draining chamber 20. The washed material is discharged downward into the crushing roller 3. This process removes the dirt from the surface of the slag, preventing dirt from adhering to the surface of the device during subsequent processing, extending the service life of the device, and avoiding dirt contamination of the working environment of the device.

[0046] After being washed and drained, the slag is crushed by the crushing roller 3 and falls downwards onto the conveyor belt device 4. It is then conveyed to the right by the conveyor belt device 4. When it reaches the area below the magnetic separation roller 21, the magnetic minerals such as pyrite in the crushed slag are adsorbed and separated by the magnetic separation roller 21. The magnetically separated slag continues to be conveyed to the right to the next process. The minerals accumulated on the surface of the magnetic separation roller 21 can be pushed backwards along the surface of the magnetic separation roller 21 by the lead screw guide 22, which drives the cleaning plate 23 to move backwards. This pushes the minerals on the surface of the magnetic separation roller 21 onto the recovery box 24. The minerals above the recovery box 24 lose their magnetic attraction and fall downwards into the recovery box 24 to complete the recovery. In this way, the magnetic minerals in the slag can be recovered, improving the resource utilization efficiency.

[0047] This concludes the description of the working principle of the device.
