Description

Technical Field

[0001] This utility model relates to the field of mineral processing technology, and more specifically, to a flotation device for treating coarse phosphorus tailings. Background Technology

[0002] Phosphate tailings are waste materials left over after the beneficiation process of phosphate rock. They mainly contain phosphate minerals, carbonate minerals, silicate minerals, etc., and have a complex chemical composition. They contain a certain amount of useful elements and harmful elements. However, the coarse-grained part of phosphate tailings has a low content of harmful elements and can be used as aggregate to prepare backfill materials to solve the environmental and land occupation problems caused by tailings storage.

[0003] Currently, flotation equipment is commonly used for screening coarse phosphate tailings. Current flotation equipment, such as flotation machines, involves adding reagents to treat the slurry, stirring and aerating it, causing some mineral particles to selectively adhere to the air bubbles, float to the surface of the slurry and be scraped off to form a froth product, while the rest remain in the slurry, thus achieving the purpose of separating minerals.

[0004] The froth product is scraped off by the scraper of the flotation equipment to achieve the flotation function. However, in actual use, the foam and the mineral particles inside the foam are relatively wet. When the scraper is scraped off, some foam and mineral particles will stick to the scraper and return to the pulp with the scraper, resulting in poor discharge efficiency. Therefore, it is necessary to improve and optimize it. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a flotation device for treating coarse phosphorus tailings, which has the advantage of good discharge effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flotation device for treating coarse phosphorus tailings, comprising a flotation cell, wherein a feed inlet is provided on the right side of the flotation cell, and discharge outlets are provided on both the front and rear sides of the flotation cell;

[0007] Fixed plates are fixedly installed on both the left and right sides of the discharge ports on both the front and rear sides. A rotating shaft is rotatably installed between the two sets of fixed plates. A discharge plate is fixedly installed on the outer wall of the rotating shaft. A guide groove is opened on the side of each set of fixed plates facing the inside of the flotation cell. A guide wheel is movably installed inside the guide groove. A scraper is rotatably installed between the guide wheels on both sides. The number of scrapers is the same as the number of blades on the discharge plate. The scraper is movably sleeved on the outer wall of the discharge plate. The scraper is used to scrape off foam and mineral particles on the discharge plate. A blower shell is fixedly installed inside the flotation cell. A fan blade is rotatably installed inside the blower shell. A hollow cylinder is fixedly installed on the top of the blower shell.

[0008] As a preferred technical solution of this utility model, a first gear is rotatably installed on the top of the hollow cylinder, and the first gear is rotatably installed on the top inner wall of the flotation cell.

[0009] A drive motor is fixedly installed at the top of the flotation cell. The output shaft of the drive motor passes through the interior of the flotation cell and is fixedly connected to the first gear. A drive rod is fixedly installed at the bottom of the first gear. The bottom of the drive rod passes through the interior of the blower housing and is fixedly connected to the fan blade.

[0010] As a preferred embodiment of this utility model, a first transmission wheel is rotatably mounted on the outer wall of the fixed plate on the right side, and the first transmission wheel is fixedly connected to the rotating shaft.

[0011] As a preferred embodiment of this utility model, a discharge motor is fixedly installed on the top of the flotation cell, and a second transmission wheel is rotatably installed on the top of the flotation cell.

[0012] As a preferred technical solution of this utility model, air intake ports are provided on the front and rear outer walls of the hollow cylinder, and the air intake ports are located above the discharge port to prevent slurry from entering the air intake port.

[0013] As a preferred embodiment of this utility model, a fixed shell is fixedly installed on the top of the inner wall of the flotation cell. The fixed shell is located outside the first gear, and teeth are provided inside the fixed shell.

[0014] As a preferred embodiment of this utility model, the teeth are provided with two sets of second gears inside, wherein one end of the second gear meshes with the teeth, the other end of the second gear meshes with the first gear, and a stirring rod is fixedly installed at the bottom of the second gear.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses the operation of a drive motor to enable the fan blades to provide agitation and air blowing for the slurry, creating a layer of foam on the surface of the slurry.

[0025] 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.

[0026] like Figures 1 to 6 As shown, this utility model provides a flotation device for treating coarse phosphorus tailings, including a flotation cell 1, a feed inlet 2 on the right side of the flotation cell 1, and discharge outlets 3 on both the front and rear sides of the flotation cell 1.

[0027] Fixed plates 4 are fixedly installed on both the left and right sides of the discharge ports 3 on both the front and rear sides. A rotating shaft 5 is rotatably installed between the two sets of fixed plates 4. A discharge plate 8 is fixedly installed on the outer wall of the rotating shaft 5. A guide groove 11 is opened on the side of the two sets of fixed plates 4 facing the inside of the flotation cell 1. A guide wheel 12 is movably installed inside the guide groove 11. A scraper 13 is rotatably installed between the guide wheels 12 on the left and right sides. The number of scrapers 13 is the same as the number of blades on the discharge plate 8. The scrapers 13 are movably sleeved on the outer wall of the discharge plate 8. The scrapers 13 are used to scrape off the foam and mineral particles on the discharge plate 8. A blower shell 14 is fixedly installed inside the flotation cell 1. A fan blade 15 is rotatably installed inside the blower shell 14. A hollow cylinder 17 is fixedly installed on the top of the blower shell 14.

[0028] When screening phosphorus tailings is required, the workers first inject the prepared slurry into the flotation cell 1 through the feed inlet 2. Then, they start the drive motor 20. The output shaft of the drive motor 20 drives the first gear 19 to rotate. The rotation of the first gear 19 drives the drive rod 16 to rotate. The drive rod 16 then drives the fan blade 15 to rotate. The rotation of the fan blade 15 agitates the slurry inside the flotation cell 1. Since the hollow cylinder 17 is hollow, the fan blade 15 draws in external gas through the air intake 18 as it rotates, thus achieving the aeration and agitation function. After a long reaction period, a layer of foam will float on the surface of the slurry inside the flotation cell 1. At this time, the staff starts the discharge motor 9, which drives the second transmission wheel 7 to rotate. The second transmission wheel 7 and the first transmission wheel 6 are connected by a belt 10, which causes the first transmission wheel 6 to drive the discharge plate 8 to rotate through the rotating shaft 5. The rotation of the discharge plate 8 will scrape the foam on the surface of the slurry from the discharge port 3. During the scraping operation of the discharge plate 8, due to the setting of the scraper 13, the scraper 13 will rotate with the discharge plate 8. However, the two ends of the scraper 13 are restricted by the guide groove 11. When the scraper 13 rotates to the front end, it will slowly move from the root of the discharge plate 8 to the top of the discharge plate 8, thereby scraping away the ore and foam, making the discharge more thorough.

[0029] The operation of the drive motor 20 causes the fan blades 15 to provide agitation and air blowing for the slurry, resulting in a layer of foam product on the surface of the slurry. Then, the operation of the discharge motor 9 causes the discharge plate 8 to discharge the foam. While the discharge plate 8 is discharging the foam, the scraper 13 scrapes off the foam and ore from the outer wall of the discharge plate 8. Compared with traditional devices, this device can completely discharge the ore remaining on the outer wall of the discharge plate 8 while discharging the foam product, through the displacement of the scraper 13, preventing material residue, improving discharge efficiency, and shortening the flotation time.

[0030] The hollow cylinder 17 is rotatably mounted on the top of a first gear 19, which is rotatably mounted on the top inner wall of the flotation cell 1.

[0031] A drive motor 20 is fixedly installed on the top of the flotation cell 1. The output shaft of the drive motor 20 passes through the interior of the flotation cell 1 and is fixedly connected to the first gear 19. A drive rod 16 is fixedly installed on the bottom of the first gear 19. The bottom of the drive rod 16 passes through the interior of the blower housing 14 and is fixedly connected to the fan blade 15.

[0032] When the first gear 19 rotates to discharge material and blow air, the rotation of the first gear 19 will drive the second gear 23 to rotate due to the setting of the fixed shell 21. One end of the second gear 23 and the fixed shell 21 are meshed with each other through the teeth 22, so that the two sets of second gears 23 begin to revolve around the first gear 19 while rotating on their own axis. Furthermore, the two sets of stirring rods 24 begin to assist in the stirring operation, thereby improving the stirring effect.

[0033] By setting up the fixed shell 21 and the second gear 23, when the first gear 19 rotates, the two sets of second gears 23 will revolve around the first gear 19 and rotate on their own axis at the same time, further enabling the stirring rod 24 to perform all-round stirring operations. Compared with the traditional device, this device can start to assist in stirring through the two sets of stirring rods 24 while the fan blade 15 is stirring and aerating, through the transmission of the first gear 19, shortening the time required for foam generation and improving the flotation efficiency.

[0034] The first transmission wheel 6 is rotatably mounted on the outer wall of the right-side fixed plate 4, and the first transmission wheel 6 is fixedly connected to the rotating shaft 5.

[0035] The top of the flotation cell 1 is fixedly equipped with a discharge motor 9, and the top of the flotation cell 1 is rotatably equipped with a second transmission wheel 7. The output shaft of the discharge motor 9 and the second transmission wheel 7 are fixedly connected, and the first transmission wheel 6 and the second transmission wheel 7 are connected by a belt 10.

[0036] The staff starts the discharge motor 9, which drives the second transmission wheel 7 to rotate. The second transmission wheel 7 and the first transmission wheel 6 are connected by a belt 10, so that the first transmission wheel 6 drives the discharge plate 8 to rotate through the rotating shaft 5.

[0037] The hollow cylinder 17 has air intake ports 18 on its front and rear outer walls. The air intake ports 18 are located above the discharge port 3 to prevent slurry from entering the air intake ports 18.

[0038] The air intake 18 is used to draw outside air into the hollow cylinder 17, thereby generating bubbles inside the slurry.

[0039] The top of the inner wall of the flotation cell 1 is fixedly installed with a fixed shell 21, which is located outside the first gear 19. The fixed shell 21 has teeth 22 inside.

[0040] The fixed shell 21 and the first gear 19 fix the second gear 23 to prevent the second gear 23 from being misaligned.

[0041] The tooth 22 has two sets of second gears 23 inside. One end of the second gear 23 meshes with the tooth 22, and the other end of the second gear 23 meshes with the first gear 19. A stirring rod 24 is fixedly installed at the bottom of the second gear 23.

[0042] The rotation of the first gear 19 will drive the second gear 23 to rotate. One end of the second gear 23 and the fixed shell 21 are meshed with each other through teeth 22, so that the two sets of second gears 23 begin to revolve around the first gear 19 while rotating on their own axis.

[0043] Working principle and usage process of this utility model:

[0044] When screening phosphorus tailings is required, the workers first inject the prepared slurry into the flotation cell 1 through the feed inlet 2. Then, they start the drive motor 20. The output shaft of the drive motor 20 drives the first gear 19 to rotate. The rotation of the first gear 19 drives the drive rod 16 to rotate. The drive rod 16 then drives the fan blade 15 to rotate. The rotation of the fan blade 15 agitates the slurry inside the flotation cell 1. Since the hollow cylinder 17 is hollow, the fan blade 15 draws in external gas through the air intake 18 as it rotates, thus achieving the aeration and agitation function. After a long reaction period, a layer of foam will float on the surface of the slurry inside the flotation cell 1. At this time, the staff starts the discharge motor 9, which drives the second transmission wheel 7 to rotate. The second transmission wheel 7 and the first transmission wheel 6 are connected by a belt 10, which causes the first transmission wheel 6 to drive the discharge plate 8 to rotate through the rotating shaft 5. The rotation of the discharge plate 8 will scrape the foam on the surface of the slurry from the discharge port 3. During the scraping operation of the discharge plate 8, due to the setting of the scraper 13, the scraper 13 will rotate with the discharge plate 8. However, the two ends of the scraper 13 are restricted by the guide groove 11. When the scraper 13 rotates to the front end, it will slowly move from the root of the discharge plate 8 to the top of the discharge plate 8, thereby scraping away the ore and foam, making the discharge more thorough.
