Description

Technical Field

[0001] The invention relates to the technical field of fluorite flotation, in particular to a flotation device for processing fluorite concentrate. Background Art

[0002] ‌‌Fluorite concentrate refers to a fine powder product obtained through professional means such as filtering, fine grinding, layer color grading, and screening. Its main component is calcium fluoride, and it contains a small amount of impurities such as rare earth elements such as Y and Ce, Fe2O3, SiO2, and trace amounts of Cl, O3, He, etc. Fluorite concentrate is widely used in glass, ceramics, metallurgy, chemical industry, new energy and other fields. For example, it is used as a flux in steel smelting to reduce slag viscosity and improve steel quality; in the chemical industry, fluorite concentrate is an important raw material for the production of hydrofluoric acid, which is used to manufacture fluorine-containing polymers and new refrigerants. The production process of fluorite concentrate includes ore crushing, ore grinding, flotation, dehydration, drying and other process flows. During flotation, a flotation device is required to effectively separate the useful minerals from the gangue minerals in the fluorite ore to produce fluorite concentrate products that meet market demand, thereby improving flotation efficiency. Flotation device is a mechanical equipment used to extract high-purity fluorite concentrate from fluorite ore. Flotation device plays a vital role in the fluorite beneficiation process. It is the key equipment in the entire beneficiation production line. Flotation device flotation machine separates fluorite from gangue minerals by physical and chemical methods, thereby extracting high-purity fluorite concentrate. Flotation device uses bubbles to separate the target mineral (fluorite) from gangue minerals. By adjusting the pH value of the slurry and adding appropriate reagents, effective separation of minerals is achieved. The flotation device commonly used in the market for fluorite concentrate processing has low efficiency in the collision and combination of bubbles and mineral particles in traditional flotation devices, and the slurry and bubbles in the device are only in contact in the vertical direction. The contact time between bubbles and minerals is short, and the formed mineral-bubble combination cannot be destroyed. In addition, the bubbles in the foam zone are unevenly distributed, and the foam layer structure is unstable. The flotation separation efficiency and processing capacity of the device cannot be achieved at the same time. Summary of the invention

[0003] The disclosed embodiment relates to a flotation device for processing fluorite concentrate, wherein a motor controls a central axis and a guide plate to rotate together, so that a spiral channel is formed between a plurality of guide plates. After a bubble generator generates bubbles, the bubbles enter the spiral channel, and driven by the rotation of the guide plates, the bubbles change from vertical ascent to spiral ascent motion, and secondary eddy currents are generated at the same time. This special motion mode prolongs the contact time between the bubbles and the slurry, increases the chance of collision and combination, changes the motion trajectory of the bubbles in traditional flotation, overcomes the problem of low efficiency of collision and combination between bubbles and mineral particles in traditional flotation equipment, and thereby increases the probability of combination between the bubbles and hydrophobic minerals.

[0009] The present invention provides a flotation device for processing fluorite concentrate, which has the following beneficial effects: The motor controls the central shaft and the guide plates to rotate together, so that a spiral channel is formed between the multiple guide plates. After the bubble generator generates bubbles, they enter the spiral channel. Driven by the rotation of the guide plates, the bubbles change from vertical rise to spiral rise, and secondary vortexes are generated at the same time.

The large bubbles are first broken by the cutting edge of the outer ring component, and then fully dispersed by the vortex generated by the auxiliary block at the position of the middle ring component. Finally, a uniform bubble flow is formed through the guiding effect of the auxiliary groove of the inner ring component. The size of the bubbles is uniform and the movement trajectory is optimized through the three-level grading structure. The central shaft drives the fixed sleeve to rotate together at the same time, so that the top moving part pushes the force block up and down, and the swing plate swings back and forth in the foam area. The uniform distribution of foam is achieved through the screening effect of the circular hole and the staggered movement of the four groups of swing plates, which solves the technical problem of uneven distribution of bubbles in the foam area and realizes a stable foam layer structure.
