[0002] In the production process of diamond micro powder, in order to ensure the consistency of the same national standard or industry standard particle size, semi-finished slurries of the same particle size selected by different sorting machines are usually batched together. In the traditional mixing process, manual mixing is used for mixing, and the mixing efficiency is extremely low. Some existing projects use diaphragm pumps for suction and mixing, which improves the degree of production automation and batching efficiency.

[0003] However, the existing self-priming pump needs to filter the slurry when in use to prevent the slurry from containing too large particles, which affects the product quality. However, depending on the product type, the particle size required in the process is different, resulting in the need to frequently replace the filter during production, which seriously affects the slurry production efficiency and degree of automation. In addition, since the diamond slurry contains a certain concentration of sodium silicate or hydrochloric acid, it is corrosive and can easily corrode the skin during operation. Therefore, an automatic device for extracting diamond micropowder semi-finished product slurry is needed to solve the above problems. Summary of the invention
