Description

Technical Field

[0001] This utility model relates to the field of mineral processing foam tank technology, specifically a mineral processing foam tank for flotation workshops. Background Technology

[0002] A mineral processing froth tank mainly consists of a tank body, a stirring mechanism, an aeration device, and a froth scraping mechanism. The tank body is the container that holds the slurry and carries out the flotation process; it is usually made of wear-resistant and corrosion-resistant materials. The stirring mechanism generally consists of a motor, a stirring shaft, and an impeller, which agitates the slurry at high speed to fully disperse the ore particles. The aeration device is responsible for introducing air into the slurry, generating a large number of tiny bubbles. The froth scraping mechanism is used to scrape the froth enriched with the target mineral out of the tank body. Its working principle is based on the differences in the physicochemical properties of the mineral surface. During the froth flotation process, various flotation reagents, such as collectors and flotation initiators, are first added to the slurry in the mineral processing froth tank. Foaming agents, such as collectors, selectively adsorb onto the surface of target minerals, making their surface hydrophobic; foaming agents reduce the surface tension of water, promoting the formation of stable bubbles after aeration. The stirring mechanism thoroughly mixes the slurry, reagents, and bubbles. Target mineral particles adhere to the bubbles and float to the surface of the slurry, forming a foam layer. Finally, the foam scraping mechanism scrapes off the foam layer, thereby achieving the separation of target minerals from gangue minerals. By adjusting parameters such as stirring intensity, aeration volume, and reagent addition, the mineral processing foam tank can adapt to ores of different properties, effectively improving the recovery rate and grade of target minerals. It is an important guarantee for achieving efficient mineral processing in the mineral processing industry.

[0003] An investigation revealed a Chinese utility model patent (CN221965656U) disclosing a mineral processing froth tank for a flotation workshop. The tank includes a housing, a foam generator fixedly mounted at the top, an extension plate fixedly mounted on one side, a motor fixedly mounted at the top of the extension plate, a movable shaft fixedly mounted at the motor's output end, and several blades fixedly mounted on the outer side of the movable shaft. In use, the housings are arranged side-by-side, the movable shafts are aligned, and then a limiting rod is moved along a limiting groove until it passes into an adjacent limiting groove until a limiting ring is tightly against the outer side of the movable shaft. Then, a screw is rotated, moving it downwards along a screw hole until it is tightly against the outer side of the limiting rod, fixing its position and preventing further movement along the limiting groove. This allows adjacent movable shafts to connect. Installation and connection are simple, convenient, and quick. One motor can drive multiple movable shafts, saving power and facilitating subsequent maintenance.

[0004] When used by users, the aforementioned patents employ a single method of motor fixing, often using simple bolts. This lacks a symmetrical fixing structure and shaft adaptation design, making the motor prone to shaking and vibration during long-term high-speed operation. This not only affects the mixing effect of the mixing plate on the slurry and reduces the uniformity of mineral mixing, but also accelerates the wear of the motor and transmission components, shortening the service life of the equipment. Furthermore, most existing foam tanks do not have a dedicated heat dissipation structure or are only equipped with a few heat dissipation holes, which is insufficient to meet the heat dissipation requirements of the motor during long-term continuous operation. When the motor operates in a high-temperature environment, it is prone to performance degradation and increased failure rate, which in turn affects the continuity and stability of the entire mineral processing process, resulting in large fluctuations in mineral processing recovery rate and grade.
