[0002] In the production and application of synthetic diamond micron powder, its particle size uniformity directly determines the product quality in downstream diamond tool manufacturing, precision polishing, and other scenarios. Therefore, it is necessary to achieve precise separation of micron powders of different particle sizes through grading and screening. Existing high-efficiency grading and particle size screening devices for synthetic diamond micron powder cannot quickly disassemble and clean or replace the screen when problems such as clogging or wear occur, resulting in increased equipment downtime for maintenance and reduced maintenance convenience. Furthermore, the feed inlet cannot be closed during the screening process, and the micron dust generated inside the screening box due to vibration and airflow can easily escape from the feed inlet, causing a large amount of internal dust to diffuse outward, resulting in low environmental adaptability.

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 protection scope of the present utility model.
[0029] Reference Figures 1-5 An embodiment of this utility model is provided: a high-efficiency grading particle size screening device for synthetic diamond micro powder, including a screening box 1, a feed inlet 14 fixedly connected to the top of the screening box 1, a dustproof component 15 for improving environmental adaptability connected to the outside of the feed inlet 14, and a detachable multi-stage screening component 2 for improving maintenance convenience connected inside the screening box 1.
[0030] The detachable multi-stage screening assembly 2 includes a first screen 3 and a mounting plate 7. A second screen 4 is located below the first screen 3, and a third screen 5 is located below the second screen 4. The apertures of the three screens decrease sequentially to screen out micro powders of different particle sizes. Mounting blocks 6 are fixedly connected to one side of each of the first screen 3, the second screen 4, and the third screen 5 to provide a sliding mounting base. Multiple sets of mounting plates 7 are provided, and the outer sides of each set of mounting plates 7 are fixedly connected to the inner side of the screening box 1. Mounting grooves 8 are opened on the inner side of each set of mounting plates 7. The mounting blocks 6 slide inside the mounting grooves 8 to achieve indirect connection between the first screen 3, the second screen 4, and the third screen 5 and the screening box 1.
[0031] Multiple through slots 9 are provided on one side of the screening box 1. One end of the first screen 3, the second screen 4, and the third screen 5 slides inside the through slot 9, providing an installation channel. One end of the first screen 3, the second screen 4, and the third screen 5 is fixedly connected to a connecting block 10. One end of the connecting block 10 is fixedly connected to a fixing plate 11. A sealing strip 12 is fixedly connected to the inner side of the fixing plate 11 to enhance the sealing of the through slot 9 and prevent internal micro powder from leaking out of the through slot 9. A handle 13 is fixedly connected to the outer side of the fixing plate 11 for easy operation by the operator. The dustproof component 15 includes a dust cover 16 and a limiting plate 17. The dust cover 16 slides outside the feed inlet 14 to prevent dust from escaping. A metal plate 19 is fixedly connected to the bottom of the dust cover 16. The limiting plate 17 is fixedly sleeved outside the feed inlet 14. A strong magnetic plate 18 is fixedly connected to the top of the limiting plate 17. The strong magnetic plate 18 and the metal plate 19 are magnetically connected to keep the dust cover 16 tight. The dust cover 16 is sealed by a tight-fitting limiting plate 17. A handle 21 is fixedly connected to the top of the dust cover 16 for easy lifting by the operator. A sealing ring 20 is fixedly connected to the top of the dust cover 16 to further enhance the sealing of the feed inlet 14 and reduce dust leakage. Both the sealing ring 20 and the sealing strip 12 are made of rubber. Multiple sets of micro vibration motors 22 are provided at the bottom of the first screen 3, the second screen 4 and the third screen 5. The multiple sets of micro vibration motors 22 are fixedly installed inside the screening box 1 by bolts to improve screening efficiency and reduce clogging. A controller 23 is fixedly installed on the outside of the screening box 1 by bolts to control the start and stop and vibration frequency of the micro vibration motors 22. The controller 23 and the micro vibration motors 22 are electrically connected. Multiple sets of discharge ports 24 are opened on the other side of the screening box 1 away from the through channel 9 to realize material distribution and collection. Each set of discharge ports 24 is hinged with a baffle 25.
[0032] Working principle: During operation, the dust cover 16 is first lifted by the handle 21, at which point the strong magnetic plate 18 separates from the metal plate 19. The synthetic diamond powder to be screened is then poured into the screening box 1 through the feed inlet 14. The dust cover 16 is then lowered, allowing the strong magnetic plate 18 and metal plate 19 to reconnect magnetically. The dust cover 16 is then tightly fitted to the feed inlet 14 via the sealing ring 20. Simultaneously, the fixing plate 11 seals the through groove 9 via the sealing strip 12, ensuring a sealed environment inside the screening box 1. Next, the micro vibration motor 22 is started by the controller 23, generating vibration that is transmitted to the first screen 3, the second screen 4, and the third screen 5. The micro powder moves along the first screen 3, second screen 4, and third screen 5 under vibration, achieving the grading of micro powder of different particle sizes. After sieving, the baffles 25 at each discharge port 24 are opened, and micro powder of different particle sizes is discharged and collected from the corresponding discharge port 24. If the first screen 3, second screen 4, and third screen 5 become clogged or worn, the operator can pull the fixing plate 11 with the handle 13 to make it slide the mounting block 6 along the mounting groove 8 and the through groove 9 to complete the cleaning or replacement. After maintenance, it can be reset and used again, which improves the convenience of maintenance.
