Although polycrystalline diamond can meet the requirements of size, dimension and shape, it still cannot replace single crystal diamond in many cases. During the processing of single crystal diamond, it is screened by screening device to separate diamonds of different particle sizes.

[0004] However, the screening device for preparing functional diamond single crystals mentioned above still has some shortcomings. During the processing of single crystal diamonds, magnetic debris such as iron filings will be mixed in. The magnetic debris will not be screened out first, thereby reducing the quality of the diamond. Although multi-stage screening is possible, the screening effect is poor, which reduces the screening efficiency. Therefore, we propose a screening device for preparing functional diamond single crystals to solve the above problems. Utility Model Content

Because two rows of electromagnetic rods 10 are arranged above and below, and the upper and lower electromagnetic rods 10 are arranged crosswise, the magnetic debris in the diamond single crystal can be better adsorbed on the corresponding electromagnetic rods 10, so that the effect of removing magnetic debris is better.

[0027] In the utility model, two grooves 12 are provided on the inner walls on both sides of the screening box 1. The shaking screening assembly includes two return springs 13, a contact plate 15 fixedly connected to the screen plate 14, a driving motor 7 fixedly connected to one side of the screening box 1, and a turntable 17 rotatably connected to the inner wall of one side of the screening box 1. One end of the two return springs 13 are respectively fixedly connected to the inner wall of one side of the corresponding groove 12, and the other ends of the two return springs 13 are respectively fixedly connected to one side of the screen plate 14. A worm 19 is fixedly connected to the output shaft of the driving motor 7, and a worm wheel 18 is fixedly connected to the front side of the turntable 17. The worm 19 is meshed with the worm wheel 18. The top and bottom of the turntable 17 are fixedly connected with toggle rods 16, and the two toggle rods 16 are respectively movably abutted against one side of the corresponding contact plate 15. The sieve hole diameter of the upper screen plate 14 is larger than the sieve hole diameter of the lower screen plate 14.

[0028] The working principle is as follows: the worm 19 is driven to rotate by the driving motor 7, and the worm 19 drives the worm wheel 18 and the turntable 17 to rotate, and the turntable 17 drives the two toggle rods 16 to rotate. When the toggle rod 16 abuts against the upper contact plate 15, it will drive the upper contact plate 15 and the screen plate 14 to move right and squeeze the upper return spring 13. When it abuts against the lower contact plate 15, it will drive the lower contact plate 15 and the screen plate 14 to move left and squeeze the lower return spring 13. When the toggle rod 16 is not in contact with the contact plate 15, at this time, under the action of the return spring 13, the upper screen plate 14 quickly moves to the left and resets, while the lower screen plate 14 quickly moves to the right and resets, thereby forming a left and right reciprocating shaking of the two screen plates 14.

The diamond single crystals with the largest particles are discharged from the upper discharge pipe 11, the diamond single crystals with the middle particles are discharged from the lower discharge pipe 11, and the diamond single crystals with the smallest particles fall into the collecting box 2 for collection and processing.

[0032] In the utility model, when in use, the diamond single crystal is poured from the feed hopper 8 into the screening box 1. When the diamond single crystal flows through the pores between the electromagnetic rods 10, the magnetic impurities in the diamond single crystal are adsorbed on the electromagnetic rods 10. Since two rows of electromagnetic rods 10 are arranged above and below, and the upper and lower electromagnetic rods 10 are arranged crosswise, the magnetic impurities in the diamond single crystal can be better adsorbed on the corresponding electromagnetic rods 10, so that the effect of removing the magnetic impurities is better. When the screening is completed, the screw 6 can be loosened so that the screw 6 is separated from the card slot 9 without being aligned with the magnetic impurities. The slide plate 4 is fixed, and the installation frame 3 can be pulled out at this time, and the electromagnetic rod 10 is powered off to make it lose its magnetism, and the magnetic debris falls naturally for collection and treatment. When the cleaning is completed, the installation frame 3 and the slide plate 4 are pushed into the slide groove 5, and the screws 6 are tightened so that the screws 6 are screwed into the card groove 9, and the installation frame 3 can be fixed. The diamond single crystal after impurities removal falls onto the upper screen plate 14. At this time, the worm 19 is driven by the driving motor 7 to rotate, and the worm 19 drives the worm wheel 18 and the turntable 17 to rotate, and the turntable 17 The two toggle rods 16 are driven to rotate.

When the toggle rod 16 contacts the lower contact plate 15, the lower contact plate 15 and the screen plate 14 will be driven to move left and squeeze the lower return spring 13. When the toggle rod 16 does not contact the contact plate 15, under the action of the return spring 13, the upper screen plate 14 quickly moves left and resets, while the lower screen plate 14 is Rapid rightward reset causes the two screen plates 14 to rock back and forth. During the rocking, not only the blockage of the diamond single crystal screen plate 14 is avoided, but also the screening effect is improved, thereby improving the screening efficiency. Because the sieve holes of the upper screen plate 14 are larger than the sieve holes of the lower screen plate 14, the diamond single crystals with the largest particles are discharged from the upper discharge pipe 11, the diamond single crystals with middle particles are discharged from the lower discharge pipe 11, and the diamond single crystals with the smallest particles fall into the collection box 2 for collection and processing.
