Ultrasonic micro-powder cleaning disperser and dispersion method thereof

Abstract

The invention discloses an ultrasonic micro-powder cleaning disperser. The disperser comprises a cleaning groove and a plurality of ultrasonic dispersers mounted in the cleaning groove, wherein a moving gap is reserved between the ultrasonic dispersers and the inner wall of the cleaning groove, an opening for facilitating micro-powder placement is arranged at the top of the cleaning groove, a support frame convenient for installation of the ultrasonic dispersers is further arranged above the cleaning groove, a driving mechanism used for driving the ultrasonic dispersers to reciprocate in the cleaning groove is mounted on the support frame, and the ultrasonic dispersers comprise dispersion boxes and a plurality of ultrasonic transducers fixedly mounted in the dispersion boxes. The disperseris reasonable in design, the dispersion method of a chemical reagent is replaced by utilizing a mechanical physical method, the dispersion effect is several times of that of the common chemical reagent, the micro powder achieves the optimal dispersion effect, and meanwhile, the pollution to the micro powder is reduced to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of micropowder production and processing, in particular to an ultrasonic micropowder cleaning disperser, and also relates to a dispersing method for the ultrasonic micropowder cleaning disperser. Background technique [0002] At present, in the process of micro-powder processing, there are often small particles below 2 μm, and the number exceeds the detection ratio. The particles are adsorbed on the surface of the basic particles. During the washing process, although a dispersant is added to improve the dispersibility of the basic particles, there are still many small nano-sized particles adsorbed on the surface of the basic particles. , After cleaning, flash drying, airflow classification and other processes, the finished products still cannot meet the requirements of foreign customers for the 3μm fine powder rate to be below 5%. Contents of the invention [0003] The technical problem to be solved by th...
