Technical Field
[0001] This utility model relates to the field of diamond preparation technology, specifically to a preparation device for long-term, high-quality growth of CVD single-crystal diamond. Background Technology
[0002] Single-crystal diamond is a diamond composed of a single continuous crystal. It has a highly ordered atomic arrangement and a grain boundary-free structure, which makes it excellent in physical, chemical and optical properties. The characteristics of single-crystal diamond are hardness and wear resistance. With a Mohs hardness of 10, it is the hardest known natural material and has extremely strong wear resistance. CVD single-crystal diamond needs to be screened by a screening device during preparation.
[0003] The patent CN213435700U discloses a screening device for the preparation of functional large-particle diamond single crystals. This patent discloses a technical solution to improve screening efficiency and solves the problem that diamonds are easily stuck on the screening mesh in existing screening devices, blocking the screening holes on the mesh and preventing diamonds from passing through. If a large number of diamonds are stuck on the screening mesh, the screening speed will be reduced.
[0004] When in use, the device uses a vibrating motor to drive the screen plate to vibrate, which avoids material blockage and improves screening efficiency. However, the material trapped inside the screening chamber tends to accumulate inside the chamber, making it difficult to discharge and reducing the screening effect. Therefore, a device for preparing CVD single crystal diamond with long-term high-quality growth is proposed to solve the above problems. Utility Model Content
