Multifunctional sample tank device of laser particle analyzer and control method

Abstract

The invention discloses a multifunctional sample tank device of a laser particle analyzer and a control method, and particularly relates to the field of material detection. The device comprises a sample tank, a laser particle analyzer stirrer, an electric control module and an ultrasonic system, wherein the laser particle analyzer stirrer is arranged in the sample tank, the sample tank is providedwith a liquid inlet and a liquid outlet, the electric control module is in signal connection with the laser particle size analyzer stirrer and the ultrasonic system and is used for controlling the laser particle size analyzer stirrer and the ultrasonic system to turn on and turn off, and the ultrasonic system is connected with the sample tank and is used for emitting ultrasonic waves into the sample tank. In the testing process, the multifunctional sample tank device of the laser particle size analyzer can perform high-power ultrasonic treatment without adopting external ultrasonic treatment,is simple and convenient to operate, and can further perform high-power ultrasonic treatment when residual impurities in the sample tank are removed, and impurities are removed.

Description

technical field [0001] The invention relates to the field of material detection, in particular to a multifunctional sample pool device and control method for a laser particle size analyzer. Background technique [0002] Laser particle size analyzer is an instrument for analyzing particle size by detecting the diffraction of particles or the spatial distribution of scattered light. It has been widely used in the fields of powder processing, application and research. It is characterized by fast test speed, wide test range, and Good repeatability and authenticity, etc. [0003] However, when using a laser particle size analyzer to test the particle size, it is necessary to replace the dispersion medium in the beaker several times to clean the pipeline, add a dispersion medium (deionized water, absolute ethanol, isopropanol, etc.) The medium is relatively frequent, the operation is inconvenient, and it is time-consuming; when using ultrasonic testing, the ultrasonic intensity o...
