[0025] As described in the background section, before using existing magnetic separators to screen materials, uneven feeding of materials causes materials to easily accumulate on the outer side of the magnetic drum, while the outermost material is subject to less magnetic force and therefore cannot be adsorbed, affecting the screening effect.

[0026] To solve this technical problem, this utility model provides a novel magnetic separator, which is applied to the screening of magnetic materials;

[0027] The system includes a base plate 1, a base frame 2 fixed to the outer side of the base plate 1, a top plate 3 fixed to the inner side of the upper end of the base frame 2, a guide baffle 5 fixed to the bottom end of the top plate 3, support plates 6 on both sides of the guide baffle 5, a feeding hopper 10 at the lower end of the guide baffle 5, first L-shaped supports 11 fixed at the four corners of the bottom end of the feeding hopper 10, and a second L-shaped support 13 fixed at the center of the bottom end of the feeding hopper 10.

An outer cylinder skin 23 is rotatably connected to the outer side of the semi-magnetic roller 22. A drive assembly is provided on the inner side of the base frame 2 between the second L-shaped support 13 and the outer cylinder skin 23.

[0028] The novel magnetic separator provided by this utility model, through its overall structural design, allows the material to be shaken and vibrated by the feeding hopper 10 in conjunction with the drive assembly before it falls to the outside of the semi-magnetic drum 22 for screening, effectively improving the uniformity of feeding and ensuring the screening effect.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Example 1:

[0032] Please refer to Figure 1-7 A novel magnetic separator includes a base plate 1, a base frame 2 fixed to the outer side of the base plate 1, a top plate 3 fixed to the inner side of the upper end of the base frame 2, a feed hopper 4 fixed to the upper end of the top plate 3 for easy feeding, the top plate 3 and the feed hopper 4 are connected, and a guide baffle 5 fixed to the bottom end of the top plate 3 for guiding the material flow.

[0033] A feeding hopper 10 is provided at the lower end of the flow guide 5. In order to support the feeding hopper 10, a first L-shaped support 11 is fixed at each of the four corners of the bottom of the feeding hopper 10. Support plates 6 are provided on both sides of the flow guide 5. The support plates 6 are fixed to the top plate 3. A first connecting rod 12 is rotatably connected to the outside of each first L-shaped support 11. The upper ends of the four first connecting rods 12 are rotatably connected to the two support plates 6 respectively.

[0034] A semi-magnetic roller 22 is fixed inside the base frame 2, and an outer cylinder skin 23 is rotatably connected to the outside of the semi-magnetic roller 22. In order to facilitate the rotation of the outer cylinder skin 23 and thus screen the material, and to facilitate the vibration of the feeding hopper 10 so that the material is fed evenly before screening, a second L-shaped support 13 is fixed at the center of the bottom end of the feeding hopper 10. A drive assembly is provided inside the base frame 2 and between the second L-shaped support 13 and the outer cylinder skin 23.

[0035] Specifically, a first bearing seat 7 and a second bearing seat 8 are fixed to the inner side of the base frame 2 and at the lower end of the feeding hopper 10, respectively. The drive assembly includes a drive motor 14. The drive motor 14 is fixed to the inner side of the base frame 2. A first transmission disc 15 is fixed to the output end of the drive motor 14. A rotating shaft 16 is rotatably connected between the first bearing seat 7 and the second bearing seat 8. A second transmission disc 17 and a fourth transmission disc 25 are fixed to the outer side of the rotating shaft 16, respectively. A first transmission belt 18 is connected between the first transmission disc 15 and the second transmission disc 17. A third transmission disc 24 is fixed to one side of the outer cylinder skin 23. A second transmission belt 26 is connected between the third transmission disc 24 and the fourth transmission disc 25. An eccentric shaft 19 is also fixed to the side of the rotating shaft 16 near the first bearing seat 7. A second connecting rod 20 is rotatably connected between the eccentric shaft 19 and the second L-shaped support 13.

[0036] All of the above electrical components are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail here.

[0037] Example 2:

[0038] The novel magnetic separator provided in Example 1 has been further optimized, specifically, as follows: Figure 5-7 As shown, when the material is uniformly fed into the outside of the semi-magnetic drum 22 through the feeding hopper 10, a screen front baffle 21 is provided at one end of the feeding hopper 10 in order to facilitate the blocking of splashed material. The screen front baffle 21 is fixed to the base frame 2.

[0039] During the screening process of the material through the rotation of the outer cylinder skin 23, in order to facilitate the flow and reception of magnetic materials, a screen guide plate 9 is provided at the upper end of one end of the bottom plate 1, and the screen guide plate 9 is fixed to the base frame 2.

[0040] Self-locking casters are installed at the four corners of the bottom of the base plate 1, which facilitates flexible movement of the equipment.

[0041] The novel magnetic separator provided by this utility model is used as follows: Before screening begins, the drive motor 14 is started to drive the first transmission disk 15 to rotate. The first transmission belt 18 and the second transmission disk 17 are used to drive the rotating shaft 16 to rotate, which in turn drives the eccentric shaft 19 and the fourth transmission disk 25 fixed to the rotating shaft 16 to rotate.

[0042] When the fourth transmission disc 25 rotates, the transmission of the second transmission belt 26 and the third transmission disc 24 drives the outer cylinder skin 23 of the semi-magnetic drum 22 to rotate, which facilitates the screening of materials that fall to the outside of the semi-magnetic drum 22. When the eccentric shaft 19 rotates, the second connecting rod 20 is used to reciprocate to lift the second L-shaped support 13. With the support of the four first connecting rods 12, the feeding hopper 10 is driven to repeatedly bounce and vibrate, which makes it easier to feed the material guided inside the feeding hopper 10 evenly.

[0043] Then, the material is conveniently fed into the feeding hopper 10 through the feed hopper 4 and the guide baffle 5 to start the screening. The material is evenly fed to the outside of the rotating outer cylinder skin 23 by the vibration of the feeding hopper 10. The magnetic material in the material is attracted by the magnetic force of the semi-magnetic roller 22 and rotates with the outer cylinder skin 23 to the upper end of the screen guide plate 9. At this time, due to the semi-magnetic setting in the semi-magnetic roller 22, the magnetic material loses its attraction and falls to the upper end of the screen guide plate 9. It is then guided by the screen guide plate 9 to the upper end of the bottom plate 1 for accumulation and collection. When the non-magnetic material falls to the outside of the semi-magnetic roller 22, it is directly thrown out to the outside of the equipment by the rotation of the outer cylinder skin 23 to achieve the separation effect and complete the screening.
