Because of its high hardness and good wear resistance, it is an ideal raw material for grinding and polishing high-hardness materials such as cemented carbide, ceramics, gemstones, and optical glass. During the processing of single-crystal diamond, more magnetic substances will be introduced. In order to avoid the influence of more magnetic substances on the quality of diamond, it is necessary to magnetically separate the magnetic substances in the diamond single crystal through a magnetic separation device. Usually, the diamond single crystal to be magnetically separated is conveyed to the magnetic separation box through a conveyor belt, and then the magnetic substances in the diamond single crystal will be adsorbed by the electromagnetic ring.

[0003] After the existing diamond single crystals are conveyed by the conveyor belt and enter the magnetic separation box, they will be in a static state, resulting in that some magnetic substances located inside and at the bottom of the diamond single crystals cannot fully contact the electromagnetic ring, making the magnetic separation of the magnetic substances not thorough.

The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present invention.

[0022] Refer to Figures 1 - 4 , a magnetic separation device for preparing large-grain diamond single crystals, including a body 1. Two pairs of mounting blocks are fixedly installed on the upper surface of the body 1. A rotating shaft is horizontally rotatably installed between each pair of mounting blocks. A rotating roller is fixedly sleeved on the rotating shaft. A conveyor belt 2 is wound around the two rotating rollers. A drive motor 3 is fixedly installed on the surface of one of the mounting blocks. The output shaft of the drive motor 3 is fixedly connected to one of the rotating shafts. The side wall of the body 1 is fixedly installed with a magnetic separation box 4 through a connecting component. The connecting component includes a plurality of connecting rods 18 fixedly installed on the side wall of the body 1. The end of the connecting rod 18 away from the body 1 is fixedly connected to the surface of the magnetic separation box 4. A spiral electromagnetic ring 5 is fixedly installed on the inner wall of the magnetic separation box 4. A rotating rod 6 is vertically rotatably installed in the magnetic separation box 4 through a mounting component. The mounting component includes a rotating ring 14 rotatably sleeved on the rotating rod 6 and two symmetrically fixedly installed support rods 15 on the outer wall of the outer ring of the rotating ring 14. One end of the support rod 15 is fixedly connected to the inner wall of the magnetic separation box 4. A plurality of stirring rods 7 are fixedly installed on the surface of the rotating rod 6.

[0023] The surface of the magnetic separation box 4 is fixedly installed with an L-shaped mounting plate. The surface of the mounting plate is horizontally rotatably installed with a reciprocating lead screw 8. A slider 9 is threadedly sleeved on the reciprocating lead screw 8. The slider 9 is fixedly installed with a rack bar 10 through a connecting rod. A gear 11 meshed with the rack bar 10 is fixedly sleeved on the rotating rod 6. The slider 9 is restricted from rotating by a restricting member. The restricting member includes a restricting rod 16 fixedly installed on the surface of the mounting plate. The slider 9 is slidably sleeved on the restricting rod 16. Sprockets 12 are fixedly sleeved on the output shaft of the driving motor 3 and the reciprocating lead screw 8. A chain 13 is meshed and wound around the two sprockets 12. The bottom end of the magnetic separation box 4 is fixedly installed with a discharge pipe 19. An electric control valve is provided in the discharge pipe 19.

[0024] First, the electromagnetic ring 5 is powered on. Then, the diamond single crystals to be magnetically separated are placed on the conveyor belt 2, and the driving motor 3 is started to control the operation of the conveyor belt 2 to convey the diamond single crystals into the magnetic separation box 4. During the operation of the conveyor belt 2, at this time, under the driving action of the two sprockets 12 and the chain 13, the reciprocating lead screw 8 will rotate together with the output shaft of the driving motor 3. The slider 9 threadedly sleeved on the reciprocating lead screw 8 will drive the rack bar 10 to perform horizontal reciprocating movement under the restricting action of the restricting rod 16. During the movement, the gear 11 meshed with the rack bar 10 will drive the rotating rod 6 to perform reciprocating rotation. The multiple stirring rods 7 will stir the diamond single crystals located in the magnetic separation box 4, so that the diamond single crystals are no longer in a static state during magnetic separation. The magnetic substances in the diamond single crystals can fully contact the electromagnetic ring 5 and be magnetically attracted, improving the integrity of magnetic separation, and no additional electric driving device is required, so no additional power cost will be generated.

[0025] After magnetic separation, at this time, the electric control valve in the discharge pipe 19 is opened to open the discharge pipe 19. Then, the magnetically separated diamond single crystals will fall from the discharge pipe 19, while the magnetic substances will be attracted by the electromagnetic ring 5. After collecting the falling diamond single crystals, the electromagnetic ring 5 is powered off. At this time, the magnetic substances will also fall from the discharge pipe 19 and then can be collected.

[0026] The upper surface of the magnetic separation box 4 is fixedly installed with an inclined U-shaped guide plate 17. The top opening of the guide plate 17 corresponds to the discharge end of the conveyor belt 2.

[0027] After the diamond single crystals conveyed by the conveyor belt 2 are removed from the discharge end of the conveyor belt 2, they will fall onto the guide plate 17 and slide down along the inclined surface of the guide plate 17 to enter the magnetic separation box 4. The guide plate 17 can play a role in guiding the material, avoiding the diamond single crystals conveyed by the conveyor belt 2 from failing to smoothly enter the magnetic separation box 4.

[0028] In the present utility model, first, the electromagnetic ring 5 is powered on. Then, the diamond single crystals to be magnetic separated are placed on the conveyor belt 2, and the driving motor 3 is started to control the operation of the conveyor belt 2 to convey the diamond single crystals into the magnetic separation box 4. During the operation of the conveyor belt 2, at this time, under the driving action of the two sprockets 12 and the chain 13, the reciprocating lead screw 8 will rotate together with the output shaft of the driving motor 3. The slider 9 threadedly sleeved on the reciprocating lead screw 8 will drive the rack bar 10 to move horizontally back and forth under the limiting action of the limiting component. During the movement, the gear 11 meshed with the rack bar 10 will drive the rotating rod 6 to rotate reciprocally, and multiple stirring rods 7 will stir the diamond single crystals located in the magnetic separation box 4, so that the diamond single crystals are no longer in a static state during magnetic separation. The magnetic substances in the diamond single crystals can fully contact the electromagnetic ring 5 and be magnetically attracted, improving the integrity of magnetic separation, and no additional electric driving device is required, so no additional power cost will be generated.

[0029] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation" and the like shall be understood in a broad sense.

[0030] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
