Technical Field
[0001] This utility model relates to the technical field of synthetic diamond production equipment, specifically to a synthetic diamond circulating acid washing device. Background Technology
[0002] After synthetic diamonds are synthesized under high temperature and pressure, graphite, catalyst metals and other impurities will adhere to their surface. These impurities need to be removed by acid washing process to improve purity.
[0003] However, existing pickling devices mostly use a single pickling tank for batch processing, resulting in insufficient contact between the acid and diamond, low pickling efficiency, and the need for repeated pickling. Furthermore, the acid is directly discharged after use, resulting in low utilization and serious environmental pollution. In addition, there is a lack of targeted stratification treatment, making it difficult to efficiently remove different types of impurities. Therefore, we propose a circulating pickling device for artificial diamond. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a circulating acid pickling device for synthetic diamonds, which solves the problems of existing acid pickling devices, which mostly use a single acid pickling tank for batch processing, resulting in insufficient contact between the acid and diamond, low acid pickling efficiency, the need for repeated acid pickling, and direct discharge of acid after use, which has low utilization rate and causes serious environmental pollution. At the same time, there is a lack of targeted stratification treatment, making it difficult to efficiently remove different types of impurities.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A circulating acid pickling device for synthetic diamond includes an ultrasonic cleaning chamber, an acid buffer chamber, and a neutralization washing chamber.
