Description

Technical Field

[0002] Phosphate ore flotation is a key step in mineral processing. Its purpose is to effectively separate the target phosphate minerals from gangue minerals by adding flotation reagents, thereby obtaining high-grade phosphate concentrate. The type, dosage, timing, and method of adding flotation reagents are all important considerations. Therefore, flotation reagents are generally added using an additive device.

[0003] However, existing devices still have some problems in practical use. For example, some devices often require operators to manually add flotation reagents to the device. This method makes it difficult to ensure that the dosage of reagents added each time is accurate and consistent. It is easily affected by the operator's experience, attention and the addition environment, resulting in fluctuations in reagent concentration, which in turn affects the stability and repeatability of the flotation effect. Secondly, manual operation is labor-intensive, especially when it is necessary to add reagents frequently or in multiple ways, which is inefficient. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 2-5This utility model provides an embodiment of an automatic addition device for phosphate rock flotation reagents, comprising a housing 1, a flotation tank 2 fixedly connected to the top of the inner wall of the housing 1, a pouring port 20 fixedly connected to the front end of the flotation tank 2, an addition box 5 fixedly connected to the front end of the pouring port 20, a detector 15 fixedly connected to the top of the addition box 5, a second motor fixedly connected to the inner wall of the detector 15, a gear 6 fixedly connected to the drive end of the second motor, a sliding assembly provided on the outer wall of the gear 6, the sliding assembly including a connecting rod 7 fixedly connected to the outer wall of the gear 6, and a second toothed plate 10 and a first toothed plate 8 respectively meshing with the left and right ends of the connecting rod 7. A connecting rod 9 is fixedly connected to one end of both the toothed plate 10 and the first toothed plate 8. The outer wall of the connecting rod 9 slides on the inner wall of the adding box 5. The bottom end of the connecting rod 9 is rotatably connected to the tilting chamber 21. The outer wall of the tilting chamber 21 is rotatably connected to the sliding rod 11. The outer wall of the sliding rod 11 slides on the inner wall of the adding box 5. Sliding grooves 22 are provided on both the left and right sides of the inner wall of the adding box 5. The sliding rod 11 slides in the sliding grooves 22. The bottom end of the gear 6 rotates on the top end of the inner wall of the adding box 5. The bottom end of the adding box 5 is fixedly connected to the top end of the outer wall of the box body 1. A second feed port 19 is fixedly connected to the front side of the top end of the adding box 5. The second feed port 19 is used to add the medicine into the adding box 5.

[0019] Specifically, the required flotation reagents are quantitatively added to the addition tank 5 through the second feed inlet 19. Then, the first motor 3 is started, driving the stirring rod 18 below it to rotate at high speed. Simultaneously, the phosphate rock to be flotated is fed into the flotation tank 2 through the first feed inlet 13, along with an appropriate amount of water. The rotation of the stirring rod 18 not only promotes uniform mixing of the slurry but also further crushes and refines larger phosphate rock particles, creating favorable conditions for the subsequent flotation reaction. Next, the second motor is started, driving the connected gear 6 to rotate. The rotation of gear 6 then moves the connecting rod 7. The movement of the connecting rod 7 is further transmitted to the first toothed plate 8 and the second toothed plate 10, causing them to float relative to each other. This motion is then transmitted to the upper tilting chamber 21 via the connecting rod 9, causing the connecting rod 9 to pull the tilting chamber 21 to move synchronously up and down. When the tilting chamber 21 moves downwards, it scoops out the flotation reagent from the addition tank 5. Then, with the assistance of the sliding rod 11, the tilting chamber 21 carrying the reagent begins to slide horizontally in the groove 22 inside the addition tank 5, transporting the reagent to a predetermined position. When the sliding rod 11 slides to the top of the groove 22, it causes the sliding rod 11 to slide outwards. This action, linked to the connecting rod 9, causes the tilting chamber 21 to rotate, allowing it to accurately and evenly pour the collected flotation reagents into the operating flotation tank 2 through the tilting port 20 below. This allows the reagents to quickly mix with the slurry and begin the flotation process on the phosphate rock. During flotation, the target phosphate rock particles become hydrophobic due to the reagents, preferentially adhering to the bubbles generated in the slurry and rising to the water surface with the bubbles, forming a foam layer rich in the target minerals. Simultaneously, the detector 15 monitors the concentration of the slurry or flotation indicators inside the flotation tank 2 in real time. Once the detection results are available... Once the flotation effect has reached the preset concentration standard or processing requirements, the detector 15 will automatically instruct the second motor to shut down and stop the addition of reagents. At the same time, the continuous rotation of the stirring rod 18 not only ensures the suspension of the slurry and the uniformity of the reagent reaction, but also drives the scraper fixed on it to rotate repeatedly on the inner wall of the flotation tank 2. This allows the scraper to promptly and efficiently scrape up the foam layer rich in target ore that has been successfully floated to the water surface and guide it into the discharge pipe 4 above. Through the discharge pipe 4, these selected ores are continuously discharged and can be collected or further processed in subsequent dewatering, drying and other processes.

[0020] Reference Figures 1-3A water storage tank 12 is fixedly connected to the top left side of the tank body 1. A connecting pipe 16 is fixedly connected to the top of the water storage tank 12. The right end of the connecting pipe 16 passes through the inner wall of the flotation tank 2 and is rotatably connected to a stirring rod 18. A water inlet is fixedly connected to the top left side of the water storage tank 12. A spray groove is opened on the outer wall of the stirring rod 18 to spray out the water entering the stirring rod 18. A scraper is fixedly connected to the outer wall of the stirring rod 18 and rotates on the inner wall of the flotation tank 2. A first feed is fixedly connected to the top right side of the flotation tank 2. The first feed inlet 13 is used to add phosphate rock into the flotation tank 2. The bottom end of the flotation tank 2 is fixedly connected to the liquid outlet valve 14, which is used to discharge waste and reacted phosphate rock. The rear end of the flotation tank 2 is fixedly connected to the discharge pipe 4, which is used to discharge the flotated ore. The right end of the flotation tank 2 is fixedly connected to the first motor 3. The drive end of the first motor 3 penetrates the inner wall of the flotation tank 2 and is fixedly connected to the stirring rod 18. The front side of the top end of the stirring rod 18 is corresponding to the pouring port 20.

[0021] Specifically, by opening the outlet valve 14 at the bottom of the flotation tank 2, the remaining waste liquid and the tailings that failed to float are completely discharged from the tank. After emptying, to prevent the residue from drying and scaling, which would affect the next use and the life of the equipment, internal cleaning is required. At this time, clean water or a special cleaning solution can be injected into the water storage tank 12 at the bottom. The water pump 17 is then started, and the water pump 17 draws the cleaning medium from the water storage tank 12 through the connecting pipe 16. The medium is then transported into the internal channel of the stirring rod 18 through the connecting pipe 16. After the cleaning fluid is injected into the interior of the stirring rod 18, it will be evenly sprayed out through the pre-designed spray grooves on the wall of the stirring rod 18, directly washing the inner wall surface of the flotation tank 2. At the same time, the stirring rod 18 drives the scraper to rotate, so that the scraper can effectively scrape off the stubborn impurities and residual reagents attached to the inner wall during the rotation. After such thorough rinsing and scraping, the inner wall of the device is cleaned, and all cleaning waste liquid is finally discharged through the liquid outlet valve 14 at the bottom, completing the cleaning process of the entire device and preparing for the next flotation operation.

[0022] Working principle: Flotation reagents are added to the addition tank 5 through the second feed inlet 19. Then, the first motor 3 is started, driving the stirring rod 18 to rotate. The phosphate rock to be floated is then added to the flotation tank 2 through the first feed inlet 13, along with water. The stirring rod 18 further crushes the phosphate rock. Then, the second motor is started, driving the gear 6 to rotate. The gear 6 drives the connecting rod 7 to rotate left and right, causing the first toothed plate 8 and the second toothed plate 10 to float up and down relative to each other. The reciprocating up and down movement of the first toothed plate 8 and the second toothed plate 10 drives the corresponding connecting rod 9 to enter the flotation tank. The connecting rod 9 moves up and down, causing the tilting chamber 21 to move up and down. The tilting chamber 21 collects the flotation reagent from the addition box 5 and slides in the addition box 5 with the help of the sliding rod 11. Then, the sliding rod 11 slides to the top of the slide chute 22 in the addition box 5 and slides outward, causing the tilting chamber 21 to rotate with the help of the sliding rod 11 and the connecting rod 9. The tilting chamber 21 pours the reagent into the flotation tank 2 through the tilting port 20 to perform flotation treatment on the phosphate rock, so that the required ore floats to the surface of the water. At the same time, the second motor is turned off after the concentration in the flotation tank 2 is detected by the detector 15 and meets the standard. Meanwhile, the rotation of the stirring rod 18 causes the scraper to rotate within the flotation tank 2. The scraper lifts the ore floating on the water surface and sends it into the discharge pipe 4 for collection or further processing. After flotation is complete, the liquid outlet valve 14 is opened to discharge the waste liquid and waste material from the flotation tank 2. Water or cleaning solution is then added to the water storage tank 12, and the water pump 17 is started. The water pump 17 draws water or cleaning solution from the water storage tank 12 through the connecting pipe 16 and discharges it into the stirring rod 18. The rotation of the stirring rod 18 causes the water or cleaning solution to be sprayed through the spray channels on the stirring rod 18 onto the inner wall of the flotation tank 2. The rotation of the stirring rod 18 drives the scraper to rotate, cleaning the impurities and residual reagents adhering to the inner wall of the flotation tank 2 before discharging them through the liquid outlet valve 14.
