Embodiment 1

[0033] A particle size measurement device comprising:

[0034] The sample pool 6 is used to contain the samples to be tested.

[0035] The sample circulation system communicates with the sample pool 6 and is used to keep the sample to be tested in the sample pool 6 in a flowing state.

[0036] Wherein, the sample circulation system includes a dispersion container and a peristaltic pump, and the two ends of the peristaltic pump communicate with the dispersion container and the sample pool 6 through connecting pipes respectively.

[0037] A dispersing container and two peristaltic pumps can also be used, and the two ends of the two peristaltic pumps are respectively communicated with the dispersing container and the sample pool 6 through connecting pipes, so as to form a system for circulating samples.

[0038] An electric stirring head and an ultrasonic device are arranged in the dispersing container, and both the electric stirring head and the ultrasonic device are electrical...

Abstract

The invention belongs to the technical field of particle size measurement, and relates to a particle size measurement device and method. The particle size measurement device comprises a sample pool and a sample circulation system communicated with the sample pool; a diaphragm, a collimating lens, a spatial filter and a laser are sequentially arranged on one side of the sample pool; a Fourier lensand a photoelectric detector are sequentially arranged on the other side of the sample pool; incident light emitted by the laser is expanded and collimated by the spatial filter, the collimating lensand the diaphragm to form parallel light beams, and the parallel light beams enter the sample pool, are scattered by the sample pool and then are emitted from the other side of the sample pool to sequentially irradiate the Fourier lens and the photoelectric detector; a data acquisition circuit is electrically connected with the photoelectric detector; and a data processing module is electrically connected with the data acquisition circuit and is used for acquiring an electric signal and processing the electric signal to obtain particle size distribution information of a tested sample. According to the invention, the particle size interval corresponding to the detection area of a receiver can be dynamically divided, and the spatial resolution of particle size measurement is improved.

Description

technical field [0001] The invention belongs to the technical field of particle size measurement, and in particular relates to a particle size measurement device and method based on the Mie scattering theory. Background technique [0002] Particles are particles with a specific geometric shape ranging from millimeters to nanometers, such as powdery substances that are often seen in life, fog droplets in the air and bubbles in water, all of which can be called particles. Usually, we define the particle size as the particle size of the particle. In the particle population, the percentage of particles of different sizes in the total particle population is defined as the particle size distribution. [0003] With the advancement of science and technology, tiny particulate matter plays an increasingly important role in daily life and industrial production. In some fields, in order to understand the impact of particles on product performance indicators, the requirements for the m...
