Description

Technical Field

[0001] The utility model relates to the technical field of diamond pickling, in particular to a diamond pickling device for preventing material precipitation. Background Art

[0002] Synthetic diamonds are produced by applying high temperature and high pressure to a graphite core in a high-pressure mold using a six-sided hydraulic press. After synthesis, impurities such as graphite, silica, and alumina particles adhere to the surface of the synthetic diamond. To improve the purity of synthetic diamonds, the synthesized diamonds need to be cleaned. The commonly used cleaning method is to first clean the synthetic diamonds with a mixture of nitric acid and sulfuric acid to oxidize the carbon on the diamond surface to carbon dioxide. The diamonds are then boiled and washed with heated sodium hydroxide to remove the silica and alumina particles.

[0003] Currently, common artificial diamond pickling equipment mainly consists of two parts: a pickling tank and a stirring device. When in use, artificial diamonds are directly thrown into the pickling tank and stirred and pickled by the stirring device. However, the existing stirring device uses an ordinary stirring slurry for stirring. When a large number of diamonds need to be cleaned, due to the weight of the diamonds themselves, they are easily deposited at the bottom of the pickling tank, resulting in incomplete cleaning effect. Therefore, it is necessary to propose a diamond pickling device that prevents material sedimentation to solve the above-mentioned problems. Utility Model Content
