Problems solved by technology
In the teaching process and on-site operation, there is currently no instrument or equipment that can quantitatively determine the characteristics of the flotation bubbles. The qualitative characteristics of the bubbles are obtained by the human naked eye, which makes students unable to correctly understand the theoretical knowledge of flotation, and also has a negative effect on the actual operation. come error
[0003] At present, the characteristics of flotation bubbles can only be described qualitatively in classroom teaching, and no specific physical characteristics can be seen. Due to the lack of experimental conditions and environment for students to measure the characteristics of bubbles, the quality and effect of teaching are seriously affected, which is not conducive to Students' understanding of flotation expertise and the cultivation of innovative thinking ability

The invention discloses a teaching experiment platform for flotation bubble feature extraction and belongs to the technical field of mineral processing engineering. The teaching experiment platform for flotation bubble feature extraction mainly solves the problem that because existing floatation classroom teaching lacks an experiment platform, it is difficult for students to understand the flotation bubble generation and mineralization principle, and then the teaching quality is seriously affected. The teaching experiment platform for flotation bubble feature extraction is characterized in that the teaching experiment platform comprises a bubbler, a stainless steel conduit, a hydrophone, an audio signal acquisition module, a computer, a bubble pressing plate, a water tank, crossed clips and a support, the bubbler is connected with the stainless steel conduit, the stainless steel conduit is placed in the water tank, the bubbler and the stainless steel conduit are fixed to the support through the crossed clips, the hydrophone is connected with the audio signal acquisition module, the audio signal acquisition module is connected with a USB port of the computer, and sound wave data analysis software is installed on the computer. The teaching experiment platform for flotation bubble feature extraction has the advantages of being visualized, low in cost, easy to operate, capable of achieving both fundamentality and innovativeness and applicable to flotation classroom teaching and innovative experiment research on flotation.
Description
technical field [0001] The invention belongs to the technical field of mineral processing engineering, relates to an experiment platform, and further relates to a teaching experiment platform for feature extraction of flotation bubbles. Background technique [0002] Flotation is the process of separating mineral particles by using the difference in physical and chemical properties of the mineral surface. It is the most widely used mineral processing method. It has been used as an industrialized mineral separation for more than 100 years. Almost all ores can be separated by flotation. . Therefore, flotation is one of the main compulsory courses for mineral processing engineering majors in colleges and universities. The selective adhesion of various ore particles to air bubbles during flotation is determined by the physical and chemical properties of the three-phase interface composed of ore particles, water, and air bubbles. The flotation effect is mainly determined by four ...
