A device for measuring bubble capture efficiency and monitoring bubble merger process

Abstract

A device for measuring the capture efficiency of bubbles on particles and monitoring the merger process between bubbles, comprising a bubble moving device, a bubble generating regulator group, an observation room, an image acquisition device and a processing terminal; the observation room includes a solution holding area, a float The particle holding area and the collection area are selected; the bubble generating regulator group is installed on the bubble moving device, and the bubble generating end faces the observation chamber; the bubble moving device drives the bubble generating adjustment group to be placed in the The solvent holding area, the flotation particle holding area and the collection area move back and forth; the image acquisition device is electrically connected to the processing terminal, and its monitoring area covers the observation chamber; the present invention generates air bubbles The regulator realizes the precise adjustment of the size of the bubbles, and through the bubble moving device, the relative position of the particles and the bubbles is precisely adjustable, and the image acquisition device directly collects the data of the bubble capture results and the bubble merger process.

Description

technical field [0001] The invention relates to the field of flotation, in particular to a device for measuring bubble capture efficiency and monitoring bubble merger process. Background technique [0002] Flotation is a technical method that uses bubbles as a carrier to separate useful minerals and gangue minerals by using the difference in physical and chemical properties of the particle surface. It has the advantages of large processing capacity, high sorting accuracy, and simple operation and maintenance. It is widely used in fine particles Mineral sorting, sewage treatment, waste paper pulp deinking and other fields. [0003] The interaction between particles and bubbles is the basis of flotation, and the interaction process between the two directly affects the results of flotation. The emerging microscopic model points out that the successful capture of useful particles by bubbles can be divided into three sub-processes: (1) collision of particles and bubbles; ②Partic...

AI Technical Summary

Problems solved by technology

[0006] The flotation process is a very complex physical and chemical process, and there are many factors that affect flotation. At present, the research on the capture efficiency of bubbles to particles and the mutual merger process between bubbles mostly uses indirect methods, while the research on the relationship between particles and bubbles, bubbles and bubbles The study of interaction behavior is slow due to the lack of necessary equipment
