[0002] Nanomaterials are a general term for ultrafine particle materials with at least one dimension in the nanoscale range in three-dimensional space. With the development of science and technology, nanomaterials are widely used in various fields. After the production of nanomaterials, there is a phenomenon of non-uniform particle size, and some nanomaterials have different properties under different particle sizes, while some nanomaterials can improve the performance of the product when the particle size is uniform. Therefore, it is necessary to automatically detect and control the particle size after the nanomaterials are produced. There are many ways to automatically detect and control. The most convenient way is to screen the nanomaterials, so as to screen out nanomaterials within a certain particle size range. This can not only realize automatic detection within the range of nanomaterials, but also control the particle size of nanomaterials within a certain range, effectively improving the use effect of nanomaterials.

However, during the airflow screening process, the nanomaterials with different particle sizes will collide with each other, and the nanomaterials after the collision will deviate during the sedimentation process and fall into the inappropriate collection container, which will reduce the accuracy of particle size control. However, the pneumatic control method is prone to errors, which makes it impossible to accurately measure the particle size range of the nanomaterial, reducing the accuracy of the nanomaterial particle size measurement.
