Description

Technical Field

[0001] The present invention relates to the technical field of flotation machines, and particularly to a flotation machine for the production of high-purity fused silica powder and a flotation method thereof. Background Art

[0002] A flotation machine is short for a flotation separator, referring to the mechanical equipment for completing the flotation process. In the flotation machine, after the pulp is treated with chemicals, through agitation and aeration, some of the mineral particles are selectively fixed on the bubbles, float to the surface of the pulp and are scraped out to form a foam product, while the rest remains in the pulp to achieve the purpose of separating minerals. There are many structural forms of flotation machines, and the most commonly used is the mechanical agitation type flotation machine. Fused silica powder also needs to be flotation-treated by a special flotation machine during the production and processing process.

[0003] However, the existing flotation machines for fused silica powder have the following problems during use: after the minerals attached to the bubbles are floated out by the flotation machine, it is necessary to cooperate with a scraping mechanism to strip the bubbles on the surface of the pulp and transfer them to a special container. However, when the existing scraping mechanism performs rotary scraping, it is easy to damage the bubbles, resulting in the scattering of the floated minerals, affecting the flotation effect, and a large amount of pulp may be incorporated into the scraping mechanism during flotation, affecting the flotation purity. The externally-guided rotary scraping method is not conducive to the separation of minerals far from the scraping mechanism. Therefore, corresponding technical solutions need to be designed to solve the existing technical problems. Summary of the Invention

However, when the existing scraping mechanism performs rotary scraping, it is easy to damage the bubbles, resulting in the scattering of the floated minerals, affecting the flotation effect, and a large amount of pulp may be incorporated into the scraping mechanism during flotation, affecting the flotation purity.
