Problems solved by technology

Due to the powder characteristics determined by the process method, such as particle size, particle size distribution, powder geometry, etc., it is difficult to meet the requirements for the use of high-performance powders in certain fields
In the patent of CN 209189103U "Ultrasonic Nebulizer", a new type of ultrasonic nebulizer is provided, which mainly includes an outer shell and an atomization generating unit. However, this device cannot continuously atomize the atomized liquid, nor can it adjust the amount of atomization
The ultrasonic atomization and classification device provided in the announcement number CN109647639A "A Submicron Powder Ultrasonic Atomization and Classification Device and Its Application" cannot effectively control the liquid level of the ultrasonic suspension, and cannot adapt to suspensions of different concentrations
The minimum particle size of traditional powder classification is generally in the micron range, and there is still a lack of submicron particle classification technology

Abstract

The invention relates to a double-layer continuous ultrasonic atomization classification device and method. The classification device comprises a first container; the bottom of the first container isconnected with one end of an atomization pipe; the other end of the atomization pipe is connected to a second container; the second container is connected to the first container through a circulatingpipe; the atomization pipe is provided with a horizontal section, and multiple piezoelectric ceramic ultrasonic atomizers are arranged inside in the horizontal direction; the horizontal section of theatomization pipe is connected with a water mist conveying pipe through multiple communicators; one end of the water mist conveying pipe is a gas inlet end, and the other end is connected with a gas-liquid separator; and water level overflowing devices are arranged in the atomization pipe at the downstream of the multiple communicators. The double-layer continuous ultrasonic atomization classification method is higher in classification precision to meet the classification requirements of sub powder particles, and can perform continuous ultrasonic atomization classification to achieve sub-micron classification precision and high production efficiency.

Description

technical field [0001] The invention relates to the technical field of powder classification equipment, in particular to a double-layer continuous ultrasonic atomization classification device and a classification method. Background technique [0002] As an important class of industrial raw materials, fine powder is increasingly used in light industry, food, chemical industry, energy, aerospace and other fields. With the gradual increase in the performance requirements of fine powder materials in terms of particle size, purity, and morphology, the powder preparation technology is promoted to develop in the direction of narrow particle size, high precision, low cost and submicron level. [0003] Ultrasonic atomization is the process of using ultrasonic energy to make the liquid form fine droplets in the gas phase. The ultrasonic atomization method is to dissolve the ultrafine powder target body in a specific solvent, and prepare a certain concentration of mother liquor, and th...
