Abstract

The invention relates to a granularity detection device which comprises a laser diffraction system, a sample injection system and a dispersion system, wherein the laser diffraction system comprises a laser system, a receiving system and a test region; the laser system and the receiving system are respectively mounted at the two ends of the base; the laser system is connected with the receiving system through a cable; a test region is an opening region arranged between the laser system and the receiving system. By adoption of modular design, before test, the dispersion system and the sample injection system are used for dispersing a sample, so that the sizes of tested particles are representative, and the obtained result is reliable and accurate; moreover, the three modules are combined, so that movement and assembling are facilitated; by adoption of an optical theory, detection and analysis of the granularity distribution of emulsion, suspension, aerosol, powder and particles are realized in a fastest way; the granularity detection device is high in test speed, wide in test range, high in repetitiveness and authenticity and easy and convenient to operate.

Description

technical field [0001] The invention relates to a particle size detection device. Background technique [0002] The laser particle size analyzer is an instrument that analyzes the particle size through the diffraction of particles or the spatial distribution of scattered light. It measures the particle size distribution based on the physical phenomenon that particles can cause laser light to scatter. Because the laser has good monochromaticity and strong directionality, a beam of parallel laser light will irradiate to infinite distance in an infinite space without hindrance, and there is little divergence during the propagation process. The existing laser particle size analyzer has a complicated structure and is difficult to operate, and the particles to be tested are not dispersed, resulting in poor authenticity of the measured particle size. Contents of the invention [0003] The technical problem solved by the present invention is to provide a particle size detection d...
