Description

technical field [0001] The invention relates to a type selection and classification device for diamond micropowder, which belongs to the field of artificial diamond processing machinery. Background technique [0002] In the production of artificial diamond and as raw material processing operations, it is necessary to select and classify the diamond powder according to the particle size of the artificial diamond. The current diamond selection equipment often uses a sorting disc in a single electromagnetic vibration or Driven by the ultrasonic oscillation equipment, the surface of the diamond powder flowing through the surface of the sorting disc is oscillated at high frequency, so that the diamond powder is driven by the vibration force, and the diamond powder of different particle sizes is driven by its own gravity to achieve the purpose of sorting, although it can be certain To a certain extent, it meets the needs of diamond micropowder sorting operations, but on the one ha...

[0002] In the production of artificial diamond and as raw material processing operations, it is necessary to select and classify the diamond powder according to the particle size of the artificial diamond. The current diamond selection equipment often uses a sorting disc in a single electromagnetic vibration or Driven by the ultrasonic oscillation equipment, the surface of the diamond powder flowing through the surface of the sorting disc is oscillated at high frequency, so that the diamond powder is driven by the vibration force, and the diamond powder of different particle sizes is driven by its own gravity to achieve the purpose of sorting, although it can be certain To a certain extent, it meets the needs of diamond micropowder sorting operations, but on the one hand, there are defects of relatively single equipment structure and insufficient adjustment ability, which results in the relatively insufficient flexibility and versatility of the current selection equipment when performing diamond micropowder selection operations, and The type selection discs of the currently used selection equipment are processed by pressure sandblasting and other methods, and under the action of external force, a number of uniformly distributed pits are processed on the disc surface, and the diamond powder is guided and sorted through the pits. Although it can meet the needs of the type selection operation, this processing method also causes relatively poor control accuracy of the processing structure of the pit, which seriously affects the accuracy and efficiency of the fine steel stone powder type selection operation, and also leads to the current type selection. The equipment can only basically meet the needs of type selection for ordinary round crystal, continuous crystal and other structures of diamond powder, while diamond powder with special structure such as square crystal and spinel cannot meet the needs of type selection and separation, which seriously affects the selection The accuracy of the operation and the efficiency of selection, on the other hand, in the selection of diamond powder, the automation of the loading of diamond raw materials and the collection of diamond powder to complete the selection is relatively poor, resulting in the current diamond powder selection equipment. The operation efficiency is relatively low, and the operation labor intensity is relatively high. In addition, the current diamond powder selection equipment also has insufficient integration and modular design, which leads to the failure repair operation and discharge operation efficiency of the current diamond selection equipment. Low, which seriously affects the continuity and reliability of the operation of the selected equipment
