[0002] Fluorite tailings are the residues or wastes left after extracting fluorite from fluorite ore, usually containing a certain amount of unextracted fluorite, other metal minerals and impurities. In order to effectively process and recover the useful components therein, the tailings are usually subjected to flotation treatment, and flotation treatment is a commonly used mineral separation technology, which realizes separation through the characteristic differences of different mineral particles. For fluorite tailings, they may contain unextracted fluorite ore particles, and through flotation treatment, these valuable minerals can be further extracted, reducing resource waste and environmental pollution.

[0021] Figure 1 Schematically shows a tailings flotation device of the present utility model, including a tank body 1. A tank cover 12 is in contact with the top of the tank body 1. A foam discharge port 13 is provided on one radial side of the tank body 1. A discharge port 14 is opened at the bottom of the tank body 1. An aeration pipe 15 is provided on one side of the tank body 1 away from the foam discharge port. A support frame 16 is fixedly installed on the surface of the tank body 1. Support legs 17 integrally formed with the support frame 16 are provided at the bottom of the support frame 16. A fixed column 18 is provided on one side of the tank body 1. The fixed column 18 passes through the support frame 16 and is fixedly installed. The fixed column 18 is of a hollow structure. A movable column 19 is provided inside the fixed column 18. A lifting device 2 is provided inside the fixed column 18 and the movable column 19. The movable column 19 is slidably connected to the fixed column 18 through the lifting device 2. The top of the movable column 19 is fixedly connected to the tank cover 12. A stirring device 3 is provided on the top of the tank cover 12. Rounded corners 4 are opened at the sharp corners of the tank body 1. The rounded corners 4 can effectively reduce the damage caused by bumps and can also avoid scratching the user. Mounting blocks 5 are fixedly installed at the bottoms of the support legs 17. A plurality of mounting holes 51 are opened on the surface of the mounting blocks 5. The device can be fixedly installed by setting fixing tools such as bolts in the mounting holes 51. An observation window 6 is opened on the top of the tank cover 12. The observation window 6 can be made of transparent materials such as glass or acrylic board, which is convenient for observing the situation inside the tank body 1.

[0022] As Figure 2Figure 3 The lifting device 2 shown includes a threaded hole 21, which is opened in the movable column 19. A threaded rod 22 is threadedly connected in the threaded hole 21. The bottom of the threaded rod 22 is rotatably connected to the bottom of the inner wall of the fixed column 18. A worm gear 23 is fixedly installed on the outer wall of the bottom end of the threaded rod 22. A worm 24 is rotatably connected to one side of the worm gear 23. One end of the worm 24 passes through the fixed column 18 and is fixedly connected to a first motor 25.

[0023] In specific implementation, just start the first motor 25. The rotation of the first motor 25 will drive the rotation of the worm 24, and the rotation of the worm 24 will drive the rotation of the worm gear 23. The rotation of the worm gear 23 will drive the threaded rod 22 to rotate in the threaded hole 21, thereby driving the movement of the movable column 19. The movement of the movable column 19 will drive the tank cover 12 and the stirring device 3 to move. Thus, the lifting of the tank cover 12 can be controlled by controlling the forward and reverse rotation of the first motor 25.

[0024] Such as Figure 2 Figure 4 The stirring device 3 shown includes a second motor 31. A support frame 32 is fixedly installed on the surface of the second motor 31. Support columns 33 integrally formed with the support frame 32 are provided at the four corners of the bottom of the support frame 32. The rotor part of the second motor 31 is fixedly connected to a transmission column 34. The transmission column 34 passes through the tank cover 12 and enters the tank body 1. A stirring block 35 is fixedly installed at the bottom end of the transmission column 34. A magnetic coupling 7 is fixedly installed at the connection between the rotor part of the second motor 31 and the transmission column 34. The transmission column 34 is fixedly connected to the second motor 31 through the magnetic coupling 7. The magnetic coupling 7 can adopt models such as HSFO8. This model can disconnect the connection when the load is too large, thereby protecting the second motor 31.

[0025] In specific implementation, just start the lifting device 2 to open the tank cover 12, then pour the materials into the tank body 1, and then start the lifting device 2 again to close the tank cover 12. At this time, air can be injected into the tank body 1 through the air injection pipe, and then start the second motor 31. The rotation of the second motor 31 will drive the rotation of the transmission column 34, and the rotation of the transmission column 34 will drive the rotation of the stirring block 35, thereby stirring the materials in the tank body 1 to generate foam. The continuous stirring of the stirring block 35 will continuously generate foam, so that the foam accumulates together in the tank body 1. The accumulation of the foam together will gradually become higher, thereby driving the raw materials to rise. When the foam in the tank body 1 accumulates to a certain height, it will be discharged from the foam discharge port 13, thereby completing the flotation.
