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

The invention discloses a device for measuring the capturing efficiency of bubbles on particles and monitoring the merging process of the bubbles. The device comprises a bubble moving device, a bubble generation regulator group, an observation chamber, an image acquisition device and a processing terminal. The observation chamber comprises a solution containing area, a flotation particle containing area and a collecting area. The bubble generation regulator group is mounted on the bubble moving device, and a bubble generation end faces the observation chamber. The bubble moving device drives the bubble generation regulator group to sequentially move in the solvent containing area, the flotation particle containing area and the collecting area in a reciprocating mode. The image acquisition device is electrically connected with the processing terminal, and a monitoring area of the image acquisition device covers the observation chamber. According to the invention, the size of bubbles can be accurately adjusted through the bubble generation regulators, the relative positions of particles and bubbles can be accurately adjusted through the bubble moving device, and data acquisition is directly carried out on a bubble capture result and a bubble merging process through the image acquisition device.
Description
technical field [0001] The invention relates to the field of flotation, in particular to a device for measuring the bubble capture efficiency and monitoring the bubble merger process. Background technique [0002] Flotation is a technical method that uses air 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 separation accuracy, and simple operation and maintenance. It is widely used in fine particle Mineral separation, sewage treatment, waste paper pulp deinking and other fields. [0003] The interaction between particles and air bubbles is the basis of flotation. The interaction process between the two directly affects the flotation results. The emergence microscopic model points out that the successful capture of useful particles by air bubbles can be divided into three sub-processes: ① particle and air bubble col...
