Description

Technical Field

[0001] This utility model relates to the field of fluorite flotation, and more specifically, it relates to a self-cleaning fluorite flotation machine. Background Technology

[0002] Fluorite is an important non-metallic mineral that is widely used in metallurgy, chemical industry, building materials and other fields. Flotation is a mineral processing method that uses the differences in the physical and chemical properties of mineral surfaces to separate them. Its core is to separate the target mineral from the ore through bubbles, and then collect the foam with attached fluorite.

[0003] The patent with publication number CN217550077U discloses a mixed concentrate flotation machine, including a flotation machine body, a scraper on the flotation machine body, and rotating mounting seats symmetrically fixed on the left and right sides of the upper surface of the flotation machine body. The left and right ends of the scraper are rotatably mounted in the rotating mounting seats on the same side. A protective edge structure is pasted and fixed on the front side of the upper surface of the flotation machine body, and a collection tank with a self-cleaning function is fixedly mounted on the front wall of the flotation machine body.

[0004] The flotation machine in the above scheme has a self-cleaning collection tank installed on the front wall of the flotation machine body to collect accidentally overflowing foam and liquid. The collected foam and liquid are sprayed for unified collection and cleaning, ensuring a clean working environment. However, during the process of discharging foam from the surface of the slurry, some foam will stick to the surface of the scraper, causing the scraper to come into contact with dust in the air, resulting in a layer of condensate adhering to the scraper surface. This condensate will affect the subsequent fluorite flotation work and effect, requiring staff to stop the machine regularly for cleaning, which is very inconvenient.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

The collector feed pipe and the foaming agent feed pipe both pass through the fixed plate to the upper side of the temporary storage frame.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] A self-cleaning fluorite flotation machine, such as Figures 1-5As shown, the machine includes a body 1 and a feed inlet 2 on the body 1. A fixed plate 3 is fixedly connected to the body 1, and a stirring rod 4 is rotatably connected to the fixed plate 3. A limiting roller 5 is fixedly connected to one end of the stirring rod 4. A motor 6 is fixedly connected to the outer wall of the body 1. A limiting roller 7 is fixedly connected to the output shaft of the motor 6. The limiting roller 5 and the limiting roller 7 are connected by a belt 8. The body 1 is equipped with an aeration assembly for aerating the slurry. The body 1 is also equipped with a flotation mechanism for flotating fluorite. The aeration assembly includes an aeration frame 9 fixedly connected to the fixed plate 3, several one-way valves 10 fixedly connected to the aeration frame 9, and a connecting pipe 11 fixedly connected to the body 1. The one-way valves 10 can prevent the slurry from entering the aeration frame 9 and clogging it. The connecting pipe 11 is fixedly connected to the aeration frame 9 and is interconnected with it.

[0023] like Figures 1-5 As shown, before flotation, the external slurry conveying pipe is connected to the feed inlet 2, and then the slurry is conveyed into the machine body 1 through the external slurry conveying pipe. Then, the external air conveying pipe is connected to the connecting pipe 11, and the air enters the air-inflating frame 9 through the connecting pipe 11 and is then ejected from each one-way valve 10. Then, the motor 6 is turned on, and the motor 6 drives the limiting roller 7 to rotate. The limiting roller 7 then drives the limiting roller 5 to rotate through the belt 8. At this time, the stirring rod 4 will be driven by the limiting roller 5 to rotate, so that a large number of bubbles will appear in the slurry. Then, the flotation mechanism is started to scrape off the foam containing fluorite. During the flotation process, the flotation mechanism will perform self-cleaning to avoid a layer of coagulation adhering to the surface. Collectors and frothers can also be added evenly to the slurry during flotation so that fluorite can adhere to the bubbles faster and easier.

[0024] like Figures 1-5 As shown, the flotation mechanism includes a motor 12 fixedly connected to the outer wall of the body 1, a positioning rod 13 rotatably connected to the body 1, flotation plates 14 fixedly connected to both sides of the positioning rod 13, and cleaning rods 15 slidably connected to both sides of the flotation plates 14. The output shaft of the motor 12 is fixedly connected to the positioning rod 13. The body 1 and the stirring rod 4 are provided with homogenizing components for uniformly mixing the collector and frother with the slurry. The homogenizing components include a collector feed pipe 16 fixedly connected to the body 1 and a frother feed pipe fixedly connected to the body 1. 17. A temporary storage frame 18 and a discharge head 19 are fixedly connected to the stirring rod 4. The discharge head 19 and the temporary storage frame 18 are interconnected. The collector inlet pipe 16 and the foaming agent inlet pipe 17 both pass through the fixed plate 3 to the upper side of the temporary storage frame 18. The fixed plate 3 is provided with a delaying component for delaying the discharge speed of the collector and the foaming agent. The delaying component includes several connecting rods 20 fixedly connected to the fixed plate 3 and several blocking frames 21 fixedly connected to the connecting rods 20. Several through holes 22 are opened on the blocking frame 21.

[0025] like Figures 1-5 As shown, before starting the flotation mechanism, the external collector delivery pipe is connected to the collector feed pipe 16, and the external frother delivery pipe is connected to the frother feed pipe 17. The collector is then transported into the collector feed pipe 16 through the external collector delivery pipe. The collector then flows into the baffle frame 21. At this time, the motor 6 is still running and will drive the stirring rod 4 to rotate. The stirring rod 4 will then drive the temporary storage frame 18 to rotate. When the discharge head 19 on the temporary storage frame 18 rotates to correspond with the through hole 22 on the baffle frame 21, the collector in the baffle frame 21 will enter the discharge head 19 and then flow into the slurry from the discharge head 19. Because the discharge head 19 rotates with the temporary storage frame 18, the collector in the discharge head 19 will be thrown out and more evenly sprinkled on the slurry. Then, with the stirring rod 4... Stirring allows for uniform contact and reaction with the slurry, making it easier for fluorite to combine with air bubbles and float to the surface of the slurry. After the collector and slurry are mixed, the frother can be transported to the collector and frother through an external frother delivery pipe. The frother will then be mixed into the slurry and react, promoting the generation and stabilization of air bubbles, which facilitates the adhesion of fluorite to the air bubbles. Once the collector and frother are mixed with the slurry, motor 12 can be started. Motor 12 then drives the positioning rod 13 and the flotation plate 14 to rotate. At this time, the flotation plate 14 can scrape out the air bubbles to complete the flotation. When the flotation plate 14 rotates, the cleaning rod 15 will slide on the flotation plate 14 due to gravity. When the cleaning rod 15 slides, it can clean the surface of the flotation plate 14 to prevent a layer of condensate from adhering to the surface of the flotation plate 14.

[0026] like Figures 1-2 As shown, sliding rods 23 are slidably connected to both sides of the fixed plate 3. Fixed blocks 24 and scraping rods 25 are fixedly connected to both ends of the sliding rods 23, respectively. A spring 26 is sleeved between the fixed plate 3 and the fixed blocks 24. When the flotation plate 14 contacts the scraping rod 25, the spring 26 is in a deformed state. When the flotation plate 14 rotates, it will contact the scraping rod 25. Then, the flotation plate 14 continues to rotate and can press down the scraping rod 25. When the scraping rod 25 is pressed down, the spring 26 is in a deformed state. Then, the flotation plate 14 continues to rotate and no longer contacts the scraping rod 25. The spring 26 will then reset, driving the scraping rod 25 to reset, ready for the next scraping. By repeating this process, the scraping rod 25 can scrape off the air bubbles attached to the side wall of the machine body 1, preventing the air bubbles from overflowing from the side wall of the machine body 1.

[0027] like Figures 1-2 As shown, a baffle 27 is detachably connected to the body 1 to prevent bubbles from overflowing from both sides of the flotation plate 14 when the flotation plate 14 scrapes out bubbles.

[0028] Working principle: Before flotation, the external slurry conveying pipe is connected to the feed inlet 2, and then the slurry is conveyed into the machine body 1 through the external slurry conveying pipe. Then, the external air conveying pipe is connected to the connecting pipe 11, and the air enters the air-inflating frame 9 through the connecting pipe 11, and then is ejected from each one-way valve 10. Then, the motor 6 is turned on, and the motor 6 drives the limiting roller 7 to rotate. The limiting roller 7 then drives the limiting roller 5 to rotate through the belt 8. At this time, the stirring rod 4 will be driven to rotate by the limiting roller 5, thereby causing a large amount of slurry to appear in the slurry. Bubbles are generated, and then the flotation mechanism is started. Before starting the flotation mechanism, the external collector delivery pipe is connected to the collector feed pipe 16, and the external frother delivery pipe is connected to the frother feed pipe 17. Then, the collector is transported into the collector feed pipe 16 through the external collector delivery pipe. The collector will then flow into the blocking frame 21. At this time, the motor 6 is still running and will drive the stirring rod 4 to rotate. The stirring rod 4 will then drive the temporary storage frame 18 to rotate. When the discharge head 19 on the temporary storage frame 18 rotates to the through hole 22 on the blocking frame 21... Correspondingly, the collector in the blocking frame 21 enters the discharge head 19 and then flows into the slurry. Because the discharge head 19 rotates with the temporary storage frame 18, the collector in the discharge head 19 is thrown out, spreading more evenly onto the slurry. Then, with the stirring rod 4, it can react evenly with the slurry, allowing fluorite to more easily combine with air bubbles and rise to the surface of the slurry. After the collector and slurry are mixed, the frother can be transported to the collector frother through the external frother delivery pipe. The frother will then... Similarly, when mixed into the slurry and reacted, it can promote the generation and stabilization of bubbles, making it easier for fluorite to adhere to the bubbles. After the collector and frother are mixed with the slurry, motor 12 can be started. Motor 12 then drives the positioning rod 13 and the flotation plate 14 to rotate. At this time, the flotation plate 14 can scrape out the bubbles to complete the flotation. When the flotation plate 14 rotates, the cleaning rod 15 will slide on the flotation plate 14 due to gravity. When the cleaning rod 15 slides, it can clean the surface of the flotation plate 14 to prevent a layer of condensate from sticking to the surface of the flotation plate 14.

[0029] When the flotation plate 14 rotates, it will contact the scraping rod 25. Then, as the flotation plate 14 continues to rotate, it will press down the scraping rod 25. When the scraping rod 25 is pressed down, the spring 26 is in a deformed state. Then, as the flotation plate 14 continues to rotate, it will no longer contact the scraping rod 25, and the spring 26 will reset, driving the scraping rod 25 to reset, ready for the next scraping. By repeating this process, the scraping rod 25 can scrape off the air bubbles attached to the side wall of the machine body 1, preventing the air bubbles from overflowing from the side wall of the machine body 1.
