Diamond automatic type selection equipment

Abstract

One or more embodiments of the specification provide automatic diamond type selection equipment which comprises a sorting cylinder, the sorting cylinder is provided with multiple layers of sorting parts at intervals from top to bottom, each sorting part comprises a sorting disc with a center and a sorting table spirally ascending around the periphery of the sorting disc, and a sorting net is laid on each sorting table; meshes of the sorting nets are used for corresponding to the shapes and the sizes of diamond materials to be sorted, the hole diameters of the meshes of the sorting nets are sequentially reduced from top to bottom, the diamond materials to be sorted are vibrated and dispersed on the sorting disc and are spirally fed at the lower position of the sorting table along with the sorting nets, and the materials which are not matched in shape or too large in size or temporarily not vibrated and clamped into the meshes of the sorting nets are separated. The material returning part in the middle of the sorting table is used for abutting against and pushing materials which are not clamped into the meshes of the sorting net to be returned, the discharging part is arranged at the high position of the sorting table in a connected mode, and the materials which are successfully sorted, fed and clamped are used for abutting against the materials in the meshes of the sorting net to be discharged.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of diamond sorting equipment, and in particular to an automatic diamond selection equipment. Background technique [0002] Diamond is a variant of carbon that is very low in ash and is a very pure substance. The most common crystal forms of synthetic diamond are hexahedron, hexahedron, octahedron, and irregular joints. Synthetic diamond abrasives are synthesized under high temperature and ultra-high pressure conditions. The pressure and temperature conditions in the high-pressure chamber are not completely consistent, and the grown diamonds are not the same, so their properties are also different. Studies have shown that the strength and crushing performance of diamond abrasive grains mainly depend on its crystal shape and its regularity, internal defects and impurity content and distribution form. [0003] The purpose of grading and sorting treatment is to make the mixture o...

Problems solved by technology

[0004] At present, the single method of vibration selection is mainly used in China to sort according to the shape of single crystals. The dispersion of product indicators is still large, the efficiency is not high, and the technology is obviously insufficient. Especially in domestic medium and high-end diamond products, some low-value materials cannot Exclusion is always a major problem in the precision sorting of synthetic diamond products
