Description

Technical Field

[0001] This utility model relates to the field of mineral flotation technology, specifically to an environmentally friendly mineral flotation device. Background Technology

[0002] Mining flotation devices, also known as flotation equipment, are mechanical devices used in mining to separate ores from impurities. They effectively separate target minerals from waste materials by utilizing differences in the surface properties of minerals, thereby extracting high-purity minerals.

[0003] Chinese patent (authorization announcement number: CN 218190293 U, authorization announcement date: 2023.01.03) proposes a flotation device for mineral processing. From top to bottom, the right side of the mineral processing box is equipped with a first bearing, a first mounting plate, a second bearing, a second mounting plate, and a first connecting pipe. A support plate is fixedly connected to the top of the rear end of the mineral processing box, and a baffle is fixedly installed at the top of the support plate. A guide channel is connected to the front side of the mineral processing box, and a collection box is fixedly installed at the front end of the guide channel. A first motor is installed at the upper end of the first mounting plate, and a first motor shaft is connected to the left end of the first motor. An installation rod is connected to the left end of the first motor shaft. In this flotation device, a locking rod is installed in the first through hole and the insertion hole to fix the first motor shaft and the installation rod together. Starting the first motor drives the installation rod to rotate. A knob is fixedly installed at the upper end of the screw. Rotating the knob raises and lowers the scraper, allowing adjustment of the scraper height according to the height of the slurry foam, thus improving the efficiency of scraping off the foam from the slurry surface.

[0004] However, the above-mentioned device only has one set of scrapers, which results in a very slow scraping speed of the mineralized froth layer, thus greatly reducing production efficiency. In addition, the above-mentioned device only performs flotation on the slurry once, which cannot guarantee that most of the minerals in the slurry will be adsorbed. This leads to low utilization of mineral raw materials and failure to obtain higher economic benefits. Furthermore, waste with high mineral content is difficult to handle and can easily have an impact on the environment. In order to improve the utilization rate of mineral raw materials, accelerate the flotation speed of the slurry, and reduce the environmental impact of mineral flotation, we propose an environmentally friendly mineral flotation device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an environmentally friendly mineral flotation device. By setting up a first flotation chamber, a second flotation chamber, and a third flotation chamber on the base, and connecting the flotation chambers via a feed pipe, the slurry first passes through the first flotation chamber for flotation. The flotated slurry then enters the second and third flotation chambers for further flotation. This three-stage flotation process effectively improves the utilization rate of mineral raw materials, reduces the mineral content in waste, and thus minimizes the environmental impact of mineral flotation. The feed guiding component consists of three sets of feed guide plates, which greatly improves the scraping speed of the mineralized froth layer and solves the background problem.

Three sets of guide components, each consisting of three guide plates, are fixedly fitted on the long rod. An aeration mechanism is installed inside each of the first, second, and third flotation chambers. A fixing frame and mounting plate are fixedly installed on each of the first, second, and third flotation chambers.

[0025] Please see Figure 1-6This utility model provides a technical solution: an environmentally friendly mining flotation device, including a base 1, on which a first flotation chamber 3, a second flotation chamber 4, and a third flotation chamber 5 are fixedly installed. The first flotation chamber 3 and the second flotation chamber 4, and the second flotation chamber 4 and the third flotation chamber 5 are connected by several guide pipes 13. Several feed pipes 6 are fixedly connected to the lower right side of the first flotation chamber 3, and several discharge pipes 7 are fixedly connected to the upper left side of the third flotation chamber 5. A long rod 9 is rotatably installed on the first flotation chamber 3, and the long rod 9 rotatably passes through... Three sets of material guiding components 10 are fixedly mounted on the long rod 9 on the second flotation chamber 4 and the third flotation chamber 5. Each material guiding component 10 consists of three sets of material guiding plates. An aeration mechanism 14 is installed in the first flotation chamber 3, the second flotation chamber 4 and the third flotation chamber 5. A fixing frame 11 and a mounting plate 12 are fixedly installed on the first flotation chamber 3, the first flotation chamber 3 and the third flotation chamber 5. A drive motor 8 is fixedly installed on the first flotation chamber 3. The drive shaft of the drive motor 8 is fixedly connected to the long rod 9. A material loading rack 2 is fixedly installed on the base 1.

[0026] In operation, coal slurry enters the first flotation chamber 3 through the feed pipe 6. When the coal slurry reaches a certain depth, the aeration mechanism 14 in the first flotation chamber 3 is activated to aerate the coal slurry. At the same time, the drive motor 8 is activated, and the drive shaft of the drive motor 8 drives the long rod 9 and the three sets of material guiding components 10 to rotate. When the mineralized foam layer reaches a certain position, the three sets of material guiding plates in the material guiding components 10 begin to scrape the mineralized foam layer into the loading rack 2. The flotated slurry enters the bottom of the second flotation chamber 4 through the material guiding pipe 13 for secondary flotation, and then enters the third flotation chamber 5 for a third flotation. Finally, the tailings are discharged through the discharge pipe 7. The three-stage flotation effectively improves the utilization rate of mineral raw materials, reduces the mineral content in waste, and thus reduces the environmental impact of mineral flotation.

[0027] The aeration mechanism 14 includes a hollow sleeve 20, which is fixedly connected to the mounting plate 12. An air guide pipe 21 is fixedly connected to the hollow sleeve 20. A transmission rod 19 is rotatably mounted on the hollow sleeve 20. An air guide hood 24 is installed at the bottom of the hollow sleeve 20. The air guide hood 24 has several through holes. A stator 26 is fixedly mounted at the bottom of the air guide hood 24. A rotor 25 is installed inside the stator 26. The rotor 25 is fixedly connected to the transmission rod 19. The transmission rod 19 is rotatably connected to the stator 26. The aeration mechanism 14 also includes a stirring motor 15, which is fixedly mounted on a corresponding mounting bracket 11. A transmission pulley 16 is fixedly fitted on the rotating shaft of the stirring motor 15. A driven pulley 17 is fixedly fitted on the upper end of the transmission rod 19. A belt 18 is tensioned between the driven pulley 17 and the transmission pulley 16. Several guide plates 22 are fixedly installed in the first flotation chamber 3, the second flotation chamber 4, and the third flotation chamber 5.

[0028] When in use, start the stirring motor 15. The drive shaft of the stirring motor 15 drives the drive pulley 16 to rotate. Under the action of the belt 18, the driven pulley 17 and the drive rod 19 start to rotate. The drive rod 19 then drives the rotor 25 to rotate. Then, the air guide pipe 21 introduces air into the bottom of the hollow sleeve 20. Then, under the action of the air guide hood 24, the stator 26 and the guide plate 22, the air is stirred into bubbles by the rotor 25 and moves upward evenly to aerate the coal slurry. The slurry and air bubbles come into full contact, forming mineralized bubbles that float to the surface, and finally forming a mineralized foam layer.

[0029] Several limiting brackets 23 are fixedly installed inside the hollow sleeve 20. The limiting brackets 23 are fixedly connected to the transmission rod 19. The limiting brackets 23 can improve the stability of the transmission rod 19 when it rotates.

[0030] Working principle: During use, coal slurry enters the first flotation chamber 3 through the feed pipe 6. When the coal slurry reaches a certain depth, the stirring motor 15 in the first flotation chamber 3 is started. The drive shaft of the stirring motor 15 drives the drive pulley 16 to rotate. Under the action of the belt 18, the driven pulley 17 and the drive rod 19 start to rotate. The drive rod 19 then drives the rotor 25 to rotate. Then, the air guide pipe 21 introduces air into the bottom of the hollow sleeve 20. Then, under the action of the air guide hood 24, the stator 26 and the guide plate 22, the air is stirred into bubbles by the rotor 25 and moves upward evenly to aerate the coal slurry. The slurry and the air bubbles come into full contact to form mineralized bubbles that float to the surface and finally form a mineralized foam layer. The limiting frame 23 in the hollow sleeve 20 can improve the stability of the drive rod 19 when it rotates.

[0031] At the same time, the drive motor 8 is started. The drive shaft of the drive motor 8 drives the long rod 9 and the three sets of material guiding components 10 to rotate. When the mineralized foam layer reaches a certain position, the three sets of material guiding plates in the material guiding components 10 begin to scrape the mineralized foam layer into the loading rack 2. The slurry after flotation enters the bottom of the second flotation chamber 4 through the material guiding pipe 13 for secondary flotation, and then enters the third flotation chamber 5 for a third flotation. Finally, the tailings are discharged through the discharge pipe 7. The three-stage flotation effectively improves the utilization rate of mineral raw materials, reduces the mineral content in the waste, and thus reduces the environmental impact of mineral flotation.
