Description

Technical Field

[0001] This utility model relates to the technical field of quartz flotation equipment, specifically a small flotation machine for laboratory use. Background Technology

[0002] Quartz flotation is a separation technology based on the differences in the physicochemical properties of mineral surfaces. By adding modifiers (such as pH adjusters) to the quartz ore, the slurry environment is changed, optimizing the surface charge of quartz (quartz is negatively charged under alkaline conditions and easily combines with cationic collectors). Inhibitors (such as starch and water glass) suppress the flotation of gangue minerals. Hydrophobic quartz particles collide with and adhere to the introduced air bubbles, forming a mineralized foam layer. After being scraped off, the concentrate is obtained, while the hydrophilic gangue minerals remain in the slurry and are discharged as tailings. For example, a fused quartz flotation device disclosed in Chinese Patent Application No.: CN202122355996.6 is a large-scale quartz flotation device. It is impossible to observe the addition of reagents in real time and cannot screen out quartz concentrate. At the same time, the flotation equipment is large in size. Industrial flotation machines are usually designed with cubic meter-level volume and need to process large amounts of slurry, while laboratory research requires small-batch, high-frequency experiments. Existing equipment is difficult to match the miniaturization requirements. Furthermore, large-scale equipment consumes a lot of energy and occupies a large area, increasing the operating costs of laboratories. Traditional flotation cells are mostly closed or semi-closed structures, making it impossible to directly observe key kinetic processes such as bubble-particle adhesion and reagent dispersion in the slurry. This leads to reliance on indirect indicators (such as concentrate recovery rate and grade) for flotation mechanism research, making it difficult to dynamically optimize reagent formulations and operating parameters. Industrial equipment relies on mechanical stirring to achieve reagent dispersion, but laboratories need to precisely control the timing and mixing uniformity of trace reagent additions (such as collectors and inhibitors). Existing equipment, due to fixed stirring intensity and uneven flow field, is prone to problems such as local overload of reagents or insufficient reaction, affecting experimental reproducibility.

[0003] Therefore, we propose a small flotation machine for laboratory use. Utility Model Content

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: The stirring motor is started, and the stirring impeller is rotated through the transmission shaft to stir the quartz ore slurry in the flotation cell. The scraper motor is started, and its output shaft is connected to a rocker arm. The scraper motor drives the scraper to rotate through the rocker arm. Simultaneously, the foam situation is observed, and the scraper motor rotation is adjusted. The scraper speed is controlled, and the inhibitor is adjusted. The quartz concentrate floats to the surface under the adsorption of reagents and foam. Subsequently, the amount of inhibitor added is adjusted according to the process. The color and texture of the foam obtained through the scraper are observed. The slurry and foam situation in the flotation cell are observed in real time, and reagent adjustments are made accordingly. The concentrate is scraped out by the scraper and falls onto the placement tray through the discharge pipe, ultimately yielding the concentrate.
