Description

Technical Field

[0001] This utility model relates to the field of phosphate rock flotation technology, specifically to a mineral processing device for preventing phosphate rock accumulation. Background Technology

[0002] Phosphate rock is an important chemical mineral raw material, widely used in industries such as agriculture, medicine, matches, dyes, sugar refining, food, textiles, glass, ceramics, and national defense. In the beneficiation process of phosphate rock, flotation is one of the commonly used beneficiation methods. Its principle is to separate fine-grained minerals by utilizing the differences in the physicochemical properties of the mineral surface.

[0003] In current mineral processing equipment, the slurry tends to accumulate at the bottom of the flotation tank due to gravity, resulting in insufficient contact between some mineral particles and reagents, affecting the mixing effect. Furthermore, the foam generated during flotation tends to accumulate near the inner wall of the flotation tank, affecting foam discharge and separation efficiency. In addition, the separated slurry may contain small particles that are not fully separated, and direct discharge would result in resource waste. Therefore, a mineral processing device for phosphate ore beneficiation with anti-accumulation design is proposed to solve the problems mentioned above. Utility Model Content

This technical solution solves the problems mentioned in the background section, where current mineral processing devices tend to accumulate at the bottom of the flotation tank due to gravity, resulting in insufficient contact between some mineral particles and reagents, affecting the mixing effect. Furthermore, the foam generated during flotation tends to accumulate near the inner wall of the flotation tank, affecting foam discharge and separation efficiency. In addition, the separated slurry may contain insufficiently separated small-sized particles, and direct discharge would lead to resource waste.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Reference Figures 1-4As shown, a phosphate ore beneficiation device for preventing accumulation includes a frame 1. A flotation box 2 and a secondary beneficiation box 3 are fixedly connected to the upper end of the frame 1. The secondary beneficiation box 3 is fixedly connected to the right side of the flotation box 2. An installation groove 4 is provided on the left inner wall of the flotation box 2. A first motor 5 is fixedly installed at the lower end of the flotation box 2. The output end of the first motor 5 passes through the lower end of the flotation box 2 and is fixedly connected to a rotating shaft 6. Several evenly distributed stirring plates 7 are fixedly connected to the outer surface of the rotating shaft 6. Several inclined bottom-lifting plates 8 are fixedly connected to the outer surface of the rotating shaft 6 near the inner bottom of the flotation box 2. A lower guide block 9 and an upper guide block 10 are fixedly connected to the inner bottom and inner top of the installation groove 4, respectively. The left inner wall of the installation groove 4... An airflow plate 11 is fixedly connected. The right end of the airflow plate 11 is connected to several evenly distributed gas nozzles 12. The left end of the gas nozzles 12 is connected to an air pipe 13. The other end of the air pipe 13 passes through the left end of the flotation box 2 and extends to the left side of the flotation box 2. A drive shaft 14 is rotatably connected between the inner walls of the front and rear sides of the flotation box 2. Several evenly distributed scrapers 15 are fixedly connected to the outer surface of the drive shaft 14. A laser rangefinder 16 is installed at the top inner side of the flotation box 2. Expansion grooves 18 are opened on the inner walls of the left and right sides of the secondary flotation box 3. A spring 19 is fixedly connected to the bottom inner side of the expansion groove 18. A screen plate 17 is fixedly connected to the upper end of the spring 19. A vibration motor 30 is fixedly installed at the lower end of the screen plate 17.

[0021] Furthermore, a second motor 29 for driving the drive shaft 14 to rotate is fixedly installed at the front end of the flotation box 2. A dosing pipe 24 is connected to the left end of the flotation box 2, and a feed pipe 25 is connected to the front end of the flotation box 2. The phosphate ore slurry enters the flotation box 2 through the feed pipe 25, and the mineral processing reagents enter the flotation box 2 through the dosing pipe 24.

[0022] Furthermore, the first motor 5 drives the rotating shaft 6 to rotate, which in turn drives the stirring plate 7 to stir the slurry in the flotation box 2, so that the mineral particles and reagents in the slurry are fully mixed. At the same time, it can drive the bottom-scooping plate 8 to scoop up the slurry at the bottom of the flotation box 2 and transport it upward, preventing the slurry from accumulating at the bottom of the flotation box 2.

[0023] Furthermore, the air pipe 13 is connected to an external air source, which can deliver high-pressure gas to the gas nozzle 12. The airflow ejected by the gas nozzle 12 pushes the foam floating in the flotation box 2, causing it to move in the direction of the scraper 15, preventing the foam from accumulating near the left inner wall of the flotation box 2, and ensuring that the foam can be fully delivered by the scraper 15.

[0024] Furthermore, baffles 21 are fixedly connected to the upper end of the sieve plate 17 near the left side of the telescopic groove 18 and the lower end of the sieve plate 17 near the two telescopic grooves 18. Several evenly distributed sieve holes 20 are opened through the upper end of the sieve plate 17 between the two telescopic grooves 18.

[0025] Furthermore, a discharge port 22 is provided through the right end of the secondary selection box 3, and a guide block 23 is fixedly connected to the right end of the sieve plate 17.

[0026] Furthermore, the rear end of the secondary selection box 3 is connected to a conveying pipe 26, and the other end of the conveying pipe 26 is fixedly connected to a conveying pump 27. The conveying pump 27 is fixedly connected to the upper end of the frame 1, and the output end of the conveying pump 27 is fixedly connected to a return pipe 28. The other end of the return pipe 28 is connected to the rear end of the flotation box 2.

[0027] Furthermore, the foam entering the secondary selection box 3 will fall onto the screen plate 17. The vibrating motor 30 drives the screen plate 17 to vibrate, causing the material to jump on the screen plate 17 and be screened through the screen holes 20. The qualified material remains on the screen plate 17 and is discharged through the discharge port 22. The slurry with smaller particle size will leak from the screen holes 20 of the screen plate 17 into the inner bottom of the secondary selection box 3, and be transported back to the flotation box 2 through the conveying pump 27 and the conveying pipe 26, forming a circulation loop of slurry, so that the material that is not fully separated can re-enter the flotation box 2 for separation.

[0028] Working principle: Phosphate ore slurry enters flotation tank 2 through feed pipe 25, while mineral processing reagents are added to flotation tank 2 through reagent addition pipe 24. The first motor 5 starts, driving the rotating shaft 6 to rotate. The stirring plate 7 agitates the slurry, ensuring thorough mixing of the slurry and reagents. The bottom scoop plate 8 scoops up the slurry from the bottom and conveys it upwards, preventing bottom accumulation. An external air source delivers high-pressure gas to the gas nozzle 12 through the air pipe 13. The airflow from the gas nozzle 12 pushes the floating foam in flotation tank 2, moving it towards the scraper 15 to prevent foam accumulation near the left inner wall of flotation tank 2 and ensuring that the foam is fully conveyed out by the scraper 15. The laser rangefinder 16 monitors the slurry in flotation tank 2 in real time. The height of the slurry and the thickness of the deposits on the inner wall are monitored. When the thickness of the deposits exceeds the set value, a signal is sent to the control system to start the second motor 29, which drives the drive shaft 14 to rotate. The scraper 15 scrapes away the floating foam in the flotation box 2, allowing it to enter the secondary selection box 3 and fall onto the screen plate 17. The vibrating motor 30 drives the screen plate 17 to vibrate, causing the material to jump on the screen plate 17 and be screened through the screen holes 20. The qualified material remains on the screen plate 17 and is discharged through the discharge port 22. The slurry with smaller particle size will leak from the screen holes 20 of the screen plate 17 into the inner bottom of the secondary selection box 3, and be transported back to the flotation box 2 for separation through the conveying pump 27 and the conveying pipe 26, forming a circulating mineral processing process.
