[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figures 1 to 6 shown, the present utility model provides a diamond micropowder magnetic separation device, including a frame 1, a conveyor belt 2 is installed on the frame 1, a magnetic separation assembly 3 is arranged outside the conveyor belt 2, a feed hopper 4 is fixedly connected to the position near the left end of the top of the frame 1, and a material pushing assembly 5 is installed on the top of the frame 1;

[0032] The magnetic separation assembly 3 includes an attaching conveyor belt 31 which is arranged on the outer side of the conveyor belt 2. The middle position of the inner wall of the attaching conveyor belt 31 is fixedly connected to the conveyor belt 2 through an annular support belt 32. Cavities 33 are formed on both sides of the annular support belt 32. Permanent magnets 34 are arranged in the cavities 33 and are fixed on the outer side of the conveyor belt 2. A magnetic shielding plate 35 is fixedly connected to the inner wall of the frame 1. The magnetic shielding plate 35 is made of a metal with high magnetic permeability, such as permalloy, iron-nickel alloy, etc. These materials can effectively guide magnetic field lines, confine the magnetic field of the permanent magnet inside, reduce the influence on external magnetic substances, or adopt a shielding structure composed of multiple layers of materials with different magnetic permeabilities. Through the gradual attenuation and guidance of the magnetic field by different layers of materials, the shielding effect is enhanced. The magnetic shielding plate 35 extends into the cavity 33, placing the permanent magnet 34 on the outer side of the conveyor belt 2. By adsorbing magnetic materials with the permanent magnet 34, energy loss is reduced. The magnetic shielding plate 35 is used to shield the magnetic adsorption between the permanent magnet 34 and the magnetic materials, so that the magnetic materials leave the attaching conveyor belt 31 to circularly adsorb magnetic materials, and it is not easy for magnetic materials to accumulate and affect the adsorption effect.

[0033] Specifically, support legs 6 are fixedly connected to the positions of the four corners at the bottom of the frame 1, and support feet are arranged at the bottoms of the support legs 6.

[0034] Furthermore, the conveyor belt 2 includes a primary motor 21. The primary motor 21 is connected to a driving roller 22 through a motor shaft. The driving roller 22 is connected to a driven roller 24 through a transmission belt 23. The permanent magnets 34 are evenly distributed on the outer surface of the transmission belt 23.

[0035] Still further, the material deflecting assembly 5 includes a gantry 51. A secondary motor 52 is installed on the gantry 51. The output end of the secondary motor 52 is connected to a rotating rod 53. A material deflecting plate 54 is arranged on the rotating rod 53. By deflecting the materials with the material deflecting plate 54, the magnetic materials can fully contact the attaching conveyor belt 31 to adhere thereto, so as to facilitate full magnetic separation and is beneficial to the use of the diamond micropowder magnetic separation device.

[0036] It should be noted that a baffle plate 7 is fixedly connected to the position near the edge of the outer surface of the attaching conveyor belt 31, and the magnetic shielding plate 35 is located between the permanent magnet 34 and the attaching conveyor belt 31.

[0037] It should be noted that a blanking hopper 8 is arranged at the position corresponding to the magnetic shielding plate 35 at the bottom of the frame 1.

[0038] It should be introduced that a scraper 9 is fixed inside the frame 1, and the position of the scraper 9 corresponds to that of the magnetic shielding plate 35.

[0039] Among them, the primary motor 21 and the secondary motor 52 are prior arts and will not be elaborated here; at the same time, the present utility model also includes a power supply, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated here.

[0040] Working principle and process: Start the primary motor 21 of the conveyor belt 2. Then, the driving roller 22 drives the driven roller 24 through the conveyor belt 23. The conveyor belt 23 drives the attached conveyor belt 31 to rotate through the annular support belt 32. The permanent magnet 34 of the magnetic separation assembly rotates together with the conveyor belt 23. Pour the diamond micropowder into the feeding hopper 4, and then it falls on the attached conveyor belt 31 of the magnetic separation assembly 3 through the feeding hopper 4. Under the magnetic force adsorption of the permanent magnet 34, the magnetic materials will adhere to the attached conveyor belt 31. As the materials are conveyed, when passing through the material deflecting assembly 5, start the secondary motor 52. Then, the rotating rod 53 drives the deflecting plate 54 to rotate to turn the materials on the attached conveyor belt 31, so that the magnetic materials on the upper layer can adhere to the attached conveyor belt 31. The non-magnetic materials leave from the right end as the attached conveyor belt 31 rotates, while the magnetic materials will adhere to the outer surface of the attached conveyor belt 31. When reaching the magnetic shielding plate 35, the magnetic shielding plate 35 is located between the permanent magnet 34 and the magnetic materials at this position. The magnetic materials are no longer subjected to the magnetic force adsorption of the permanent magnet 34 and can then fall under the action of gravity and be discharged through the discharging hopper 8 to complete the magnetic separation work of the diamond micropowder.
