[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1-7 As shown, a multi-layer screening device includes a device body 1; a base 2 is provided at the bottom end of the device body 1, and a screening and material handling mechanism is provided between the device body 1 and the base 2.

[0027] The screening and material handling mechanism includes a screening plate 10, which is respectively set at the upper and lower ends of the device body 1. The left and right ends of the screening plate 10 are welded together to the inner wall of the device body 1. The front and rear ends of the top of the screening plate 10 are also welded together to a baffle plate 11. The left and right sides of the device body 1 are also provided with discharge holes 12. The left and right sides of the device body 1 are also provided with moving plates 13 near the discharge holes 12. The left and right ends of the device body 1 are also glued together to a fixing plate 26. The front and rear ends of the bottom of the fixing plate 26 are welded together to a second magnetic block 27. The front and rear ends of the top of the moving plate 13 are also glued together to a first magnetic block 25. The moving plate 13 is square in design.

[0028] During operation, porous carbon raw material is fed into the device body 1 through the top of the device body 1, and falls onto the surface of the screening plate 10 located above the device body 1. At the same time, the vibration motor 31 at the top of the base 2 is started to vibrate, so that the porous carbon raw material will move downward along the surface of the screening plate 10 located above the device body 1, and be vibrated and screened. It will then fall onto the surface of the screening plate 10 located below the device body 1. The baffle plate 11 at the top of the screening plate 10 can be used to block the porous carbon raw material. The moving plate 13 is pushed upward, which drives the slider 14 to move along the sliding groove 16 opened on the side of the first fixed block 15 until the first magnetic block 25 at the top of the moving plate 13 contacts the second magnetic block 27 at the bottom of the fixed plate 26. The moving plate 13 will be fixed in position by magnetic attraction to one side.

[0029] Furthermore, sliders 14 are also fixedly connected to the left and right sides of the movable plate 13, and the front and rear ends of the left and right ends of the device body 1 are also fixedly connected to the first fixing block 15. A groove 16 is opened at one end of the first fixing block 15, and the slider 14 is slidably connected to the groove 16. Both the slider 14 and the groove 16 are T-shaped designs.

[0030] During operation, the movable plate 13 is pushed upward, causing the slider 14 to move along the groove 16 opened on the side of the first fixed block 15.

[0031] Furthermore, a fixed base 17 is fixedly connected to one side of the movable plate 13, and a rotating plate 18 is rotatably connected to the outside of the fixed base 17. A second fixed block 19 is also fixedly connected to the front and rear ends of one side of the rotating plate 18, and the inner wall of the rotating plate 18 is circular.

[0032] During operation, the rotating plate 18 flips upward, and the top of the rotating plate 18 rotates along the outside of the fixed base 17.

[0033] Furthermore, a fixing rod 20 is fixedly connected to one end of the second fixing block 19, a movable insert 21 is slidably connected to the outside of the fixing rod 20, a pressing block 24 is fixedly connected to one side of the movable insert 21, a third fixing block 22 is slidably connected to the movable insert 21, and a device body 1 is fixedly connected to one side of the third fixing block 22. The movable insert 21 has a square design.

[0034] During operation, press the two pressing blocks 24 on both sides simultaneously towards the middle position, causing the moving insert 21 to move along the inside of the third fixing block 22 towards the middle second fixing block 19 until it is completely disengaged from the inside of the third fixing block 22. When the moving insert 21 moves, it will move along the outside of the fixing rod 20.

[0035] Furthermore, a first return spring 23 is sleeved on the outside of the fixing rod 20. One end of the first return spring 23 is fixedly connected to a second fixing block 19, and the other end of the first return spring 23 is fixedly connected to a third fixing block 22.

[0036] During operation, the movement of the movable plug 21 will compress the first return spring 23 and cause it to retract.

[0037] Furthermore, a vibration motor 31 is fixedly connected to the middle position of the top of the base 2, and the bottom of the device body 1 is fixedly connected to the top of the vibration motor 31. A sleeve rod 29 is also fixedly connected to the top of the base 2 near the corner. A moving rod 28 is slidably connected inside the sleeve rod 29. The top of the moving rod 28 is fixedly connected to the device body 1, and one end of the second return spring 30 is fixedly connected to the bottom of the moving rod 28. The other end of the second return spring 30 is fixedly connected to the bottom of the sleeve rod 29. Both the moving rod 28 and the sleeve rod 29 are circular in design.

[0038] During operation, the vibration motor 31 at the top of the base 2 is started to vibrate, so that the porous carbon raw material will move downward along the surface of the screening plate 10 at the upper position of the main body 1 of the device, and be vibrated and screened at the same time, and fall onto the surface of the screening plate 10 at the lower position inside the main body 1 of the device. The baffle plate 11 at the top of the screening plate 10 can be used to block the porous carbon raw material. During the vibration, the moving rod 28 is driven to move up and down back and forth along the inside of the sleeve rod 29, while squeezing and stretching the second return spring 30.

[0039] Working principle: When screening is required, the porous carbon raw material is first fed into the device body 1 through the top of the device body 1, thus falling onto the surface of the screening plate 10 at the top of the device body 1. At the same time, the vibration motor 31 at the top of the base 2 is started to vibrate, so that the porous carbon raw material will move downward along the surface of the screening plate 10 at the top of the device body 1, and be vibrated and screened. It then falls onto the surface of the screening plate 10 at the bottom of the device body 1. The baffle plate 11 at the top of the screening plate 10 can be used to block the porous carbon raw material. During the vibration, the moving rod 28 moves back and forth up and down along the sleeve rod 29, while squeezing and stretching the second return spring 30. After screening is completed, the pressing blocks 24 on both sides are pressed towards the middle position, driving the... The movable insert 21 moves along the inside of the third fixed block 22 towards the middle second fixed block 19 until it is completely detached from the inside of the third fixed block 22. When the movable insert 21 moves, it will move along the outside of the fixed rod 20. At the same time, the movement of the movable insert 21 will compress the first return spring 23 and retract it. Then, the rotating plate 18 will be flipped upward, and the top of the rotating plate 18 will rotate along the outside of the fixed seat 17. Then, the movable plate 13 will be pushed upward, causing the slider 14 to move along the slide groove 16 opened on the side of the first fixed block 15 until the first magnetic block 25 at the top of the movable plate 13 contacts the second magnetic block 27 at the bottom of the fixed plate 26. The movable plate 13 will be fixed in position by magnetic attraction on one side. Then, the screened raw material will be discharged through the discharge hole 12.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
