Technical Field
[0001] The utility model belongs to the technical field of chemical smelting and relates to an ultrasonic atomization multi-stage deep-layer high-pressure dosing device. Background Art
[0002] Flotation is a method based on the difference in physical and chemical properties of mineral surfaces. After the action of flotation reagents, the wettability of the surfaces of various minerals in the slurry changes, thereby expanding the difference in hydrophilicity and hydrophobicity between useful minerals and gangue, making them better separated and achieving the purpose of improving the recovery rate. The addition of reagents is crucial to the role of flotation.
[0003] The traditional dosing method is to let the reagents contact the slurry on the upper part of the mixing tank liquid surface by gravity flow through the dosing pipe, and through the stirring action of the agitator, the surface of the ore particles contacts the reagents, so as to achieve mass transfer and adsorption between the suspended ore particles and the reagent particles; the slurry flow rate in the mixing tank is fast, the reagents and the surface of the ore particles have a short action time and the stirring is uneven, which affects the flotation reagents to play their due role in time, resulting in the inability to effectively recover useful metals, and reducing the concentrate grade and recovery rate. In response to the above problems, the utility model provides a new ultrasonic atomization multi-stage deep high-pressure dosing technology, which enables better mass transfer and adsorption between the reagents and the suspended ore particles, and better enables the flotation reagents to play their role. Utility Model Content
[0004] The utility model aims to provide an ultrasonic atomization multi-stage deep high-pressure dosing device to solve the problems of the conventional dosing method, such as large waste of reagents, poor mass transfer and adsorption effect between suspended ore particles and reagent particles, and inability of flotation reagents to function quickly and well.

[0009] The beneficial effects of the utility model are:
[0010] The utility model can inject the reagent into different depths of the ore pulp in the stirring tank after atomization and pressurization, greatly reducing the mass transfer and adsorption time between the flotation reagent and the suspended ore particles, significantly improving the flotation foaming phenomenon, and significantly improving the concentrate grade and metal recovery rate.
