Description

Technical Field

[0001] This utility model relates to the technical field of diamond processing equipment, specifically to a grading and screening device for artificial single crystal diamond. Background Technology

[0002] Synthetic single-crystal diamonds have wide applications in industrial production, scientific research, and other fields. Different applications have strict requirements on parameters such as particle size and shape of synthetic single-crystal diamonds. During the production of synthetic single-crystal diamonds, grading and screening are necessary to meet the needs of different customers. Traditional synthetic single-crystal diamond grading and screening devices have many drawbacks. For example, they have low screening accuracy, failing to accurately separate diamond particles of different size ranges, resulting in inconsistent product quality; low screening efficiency and long production cycles make it difficult to meet the needs of large-scale production; moreover, some devices have complex structures and are difficult to operate, often using eccentric hammers to generate vibrations for screening, causing significant wear and tear on the screening screen or other mechanisms, resulting in high equipment maintenance costs. Therefore, developing a high-efficiency, precise, and structurally simple synthetic single-crystal diamond grading and screening device is of significant practical importance. Utility Model Content

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.

[0015] This utility model provides a new technical solution: a grading and screening device for artificial single-crystal diamond, comprising: Screening box 1, wherein the top of the screening box 1 is provided with an installation port; A screening unit is detachably installed inside the screening box 1 via an installation port. The screening unit includes: a first screening cylinder 2, a second screening cylinder 3, a third screening cylinder 4, a rotary bearing 5, and a centrifugal assembly 6. The first screening cylinder 2 is detachably installed inside the second screening cylinder 3, and the second screening cylinder 3 is detachably installed inside the third screening cylinder 4. The third screening cylinder 4 is connected to the screening box 1 via the rotary bearing 5. The inner ring of the rotary bearing 5 is located on the outer periphery of the third screening cylinder 4, and the outer ring of the rotary bearing 5 is detachably installed in the screening box 1. The centrifugal assembly 6 is located at the bottom of the screening box 1 and is used to drive the screening unit to rotate.

[0017] In this embodiment, the first screening cylinder 2, the second screening cylinder 3, and the third screening cylinder 4 are all detachably connected by snap fasteners 7.

[0018] In this embodiment, a top cover 201 is hinged to the top of the first screening cylinder 2, and the top cover 201 is provided with a top cover handle 202 for opening the top cover 201.

[0019] In this embodiment, the centrifugal assembly 6 includes: a base 601, a turntable 602, and an electromagnet 603. The base 601 is disposed at the bottom of the screening box 1, the turntable 602 is rotatably disposed inside the base 601, and the electromagnet 603 is disposed on the surface of the turntable 602.

[0020] In this embodiment, the longitudinal section of the base 601 is U-shaped.

[0021] Working Principle: In use, single-crystal diamonds are placed into the screening unit through the top cover 201. The electromagnet 603 is turned on and fixed by the adsorption metal block 401. The turntable 602 is started, and the screening unit is rotated in the screening box 1 through the set rotating bearing 5. The centrifugal force generated by the screening unit causes smaller single-crystal diamonds to pass through the primary screening hole 203 of the first screening cylinder 2 and enter the second screening cylinder 3.
