Description

Technical Field

[0001] The present invention relates to a fluorite powder flotation device, and more particularly to a fluorite powder flotation cell with a self-cleaning function. Background Art

[0002] Fluorite, also known as fluorspar, is the main source of fluorine in industry and is one of the more than 20 important non-metallic mineral raw materials in the world. Pure, colorless and transparent fluorite can be used as optical materials, and brightly colored fluorite can also be used as gemstones and raw materials for arts and crafts carving. Fluorite is also the basic raw material for the fluorine chemical industry, and its products are widely used in fields such as aerospace, aviation, refrigeration, medicine, pesticides, anti-corrosion, fire extinguishing, electronics, electric power, machinery, and atomic energy. With the continuous development of technology and the national economy, fluorite has become an important mineral raw material in modern industry, and many developed countries reserve it as an important strategic material. During the flotation process in a flotation device, the pulp treated with reagents is agitated and aerated, causing some of the mineral particles to selectively adhere to the bubbles and float to the surface of the pulp to be scraped out to form a foam product, while the rest remains in the pulp to achieve the purpose of separating minerals. Traditional fluorite powder flotation machines generally have a square structure, and natural dead corners are formed at the four corners of the bottom of the flotation cell. During flotation, the ore powder is likely to deposit at the four corners of the bottom of the flotation cell. After long-term accumulation, the flotation ability of the flotation cell will decline, affecting the flotation accuracy of fluorite powder. Summary of the Invention

The stirring paddle provided on the rotating shaft is driven by a motor to rotate at a high speed for stirring. The gear A sleeved on the rotating shaft drives the rotation of gear B and gear C, and then drives the relatively large-diameter inner gear rings A and B to rotate at a low speed. The scraping bar scrapes the foam on the surface of the pulp at the mouth of the circular tank to form a foam product. The "U"-shaped scraper makes it difficult for the heavier tailings to deposit at the bottom of the cavity, realizing the function of simultaneously solving high-speed rotation stirring and low-speed rotation scraping with the rotating shaft of the motor.

[0020] To implement the fluorite powder flotation tank with self-cleaning function of the present invention, connect the motor 6 to the switch and the power supply respectively. The fluorite powder ore pulp added with reagents enters the sleeve 21 along the feed pipe 27. Turn on the motor 6. The motor 6 drives the rotating shaft 26 to rotate at a high speed, and then drives the stirring paddle 33 to rotate at a high speed. Under the action of centrifugal force, the air in the air inlet pipe 17 is drawn into the sleeve 21 and mixed with the fluorite powder ore pulp added with reagents. The fluorite powder adheres to the foam and surges out from the lower end of the diameter-expanding cylinder 34 and floats to the surface of the ore pulp; the rotation of the rotating shaft 26 drives the gear A8 sleeved on the rotating shaft 26 to rotate at a high speed. The high-speed rotation of the gear A8 drives the gear B10 meshing with the gear A8 to rotate at a high speed. Since the gear B10 is arranged at the upper end of the rotating rod 18 and the rotating rod 18 is rotatably connected in the rotating ring 16, the high-speed rotation of the gear B10 drives the rotating rod 18 to rotate at a high speed, and then drives the gear C24 connected to the lower end of the rotating rod 18 to rotate at a high speed; Since the internal gear ring A3 is sleeved outside the gear A8 and the gear B10 and is rotatably connected to the inner wall of the circular trough 31, the rotation speed of the internal gear ring A3 meshing with the gear B10 is significantly lower than the rotation speed of the gear B10. Therefore, the internal gear ring A3 drives the scraper bar 4 connected to the top of the internal gear ring A3 to rotate at a low speed. The low-speed rotating scraper bar 4 effectively scrapes the floating foam on the surface of the ore pulp at the mouth of the circular trough 31 to the floating foam collection ring groove 14 to form a fluorite powder foam product; Since the internal gear ring B30 is sleeved outside the gear C24 and the sleeve 21 and is rotatably connected to the inner wall of the circular groove body 31, the rotation speed of the internal gear ring B30 meshing with the gear C24 is significantly reduced relative to the rotation speed of the gear C24. Therefore, the internal gear ring B30 drives the "U"-shaped scraper 32 connected to the bottom of the internal gear ring B30 to rotate at a low speed. The "U"-shaped scraper 32 rotating at a low speed effectively scrapes up the heavier tailings deposited at the bottom of the cavity 35, enabling the tailings to flow out along the slurry discharge pipe 25 together with the slurry, achieving the function of simultaneously solving high-speed rotation stirring and low-speed rotation scraping with the rotating shaft of the motor.

For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
