By adopting the technological process and reagent system of this research, most of the high-quality ilmenite concentrates can be recovered, and the discharge amount of iron - selected tailings and the storage capacity pressure of the tailing pond can be reduced.

[0003] In the process of realizing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. During use, traditional full - size ilmenite flotation devices are directly connected to a gas pipe to allow gas to automatically enter the inside of the flotation device, which slows down the speed of gas entering the flotation body. The flotation body is prone to incomplete flotation of full - size ilmenite due to low ventilation efficiency. Moreover, the air - blowing impeller cannot rotate simultaneously and at the same speed as the first pulley, so the speed of gas entering the flotation body cannot be automatically adjusted according to the speed of full - size ilmenite flotation. Therefore, a new technical solution needs to be designed to solve this problem. Content of the Utility Model

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a full - size ilmenite flotation device to solve the technical problems that current full - size ilmenite flotation devices are directly connected to a gas pipe to allow gas to automatically enter the inside of the flotation device, which slows down the speed of gas entering the flotation body, the flotation body is prone to incomplete flotation of full - size ilmenite due to low ventilation efficiency, and the air - blowing impeller cannot rotate simultaneously and at the same speed as the first pulley, so the speed of gas entering the flotation body cannot be automatically adjusted according to the speed of full - size ilmenite flotation.

[0005] To achieve the purpose of the present utility model, the technical solution adopted by the present utility model is: design a full - size ilmenite flotation device, including a flotation body. A bearing seat is fixedly installed at the top of the flotation body. One end of the bearing seat is rotatably connected to a first pulley.

The third pulley is connected to an air - blowing impeller through a driving shaft. The air - blowing impeller is connected to an air - blowing cover through an adapter bearing. A through - slot is opened at the bottom of the air - blowing cover. The periphery of the through - slot is connected to a gas pipe through an air - gathering cover.

[0006] Preferably, one end of the second belt is sleeved outside the second pulley, and the other end of the second belt is sleeved outside the third pulley.

At this time, the first pulley drives the second pulley and the components in the bearing seat to rotate at the same time. Then the second pulley drives the third belt to rotate through the second belt, and then the third belt drives the air-blowing impeller to rotate through the driving shaft. At this time, the air-blowing impeller conveys the gas in the air-blowing cover to the air-gathering cover through the through groove, and then the air-gathering cover conveys the gas to the inside of the flotation column through the air guide pipe, so as to achieve aeration of the ilmenite of all particle sizes in flotation, accelerate the speed of gas entering the flotation body, and avoid the phenomenon that the ilmenite of all particle sizes is not completely floated due to low aeration efficiency of the flotation body;

[0019] The present utility model will be further described below with reference to the accompanying drawings and embodiments:

[0020] Embodiment 1: A full-size ilmenite flotation device, see Figures 1 to 3 , including a flotation machine body 1, a bearing seat 11 is fixedly installed at the top of the flotation machine body 1, one end of the bearing seat 11 is rotatably connected to a first pulley 12, and the top of the first pulley 12 is fixedly connected to a second pulley 13. By installing the second pulley 13 at the top of the first pulley 12, the air-blowing impeller 17 can rotate simultaneously and at the same speed as the first pulley 12, so that the speed of gas entering the flotation machine body 1 can be automatically adjusted according to the speed during the full-size ilmenite flotation;

[0021] The second pulley 13 is connected to a third pulley 15 through a second belt 14. One end of the second belt 14 is sleeved outside the second pulley 13, and the other end of the second belt 14 is sleeved outside the third pulley 15. The third pulley 15 is connected to a blast impeller 17 through a driving shaft 16. One end of the driving shaft 16 is fixedly connected to the bottom end of the third pulley 15, and the other end of the driving shaft 16 is fixedly connected to the top end of the blast impeller 17. The inner ring of the connecting bearing 18 is fixedly connected to the other end of the blast impeller 17, and the outer ring of the connecting bearing 18 is fixedly connected to the bottom of the blast hood 19. The blast impeller 17 is connected to the blast hood 19 through the connecting bearing 18. A through groove 20 is provided at the bottom of the blast hood 19. The periphery of the through groove 20 is connected to an air duct 22 through an air-gathering hood 21. One end of the air-gathering hood 21 is hermetically connected to the bottom of the blast hood 19, and the other end of the air-gathering hood 21 is hermetically connected to one end of the air duct 22. The other end of the air duct 22 is hermetically connected to the outside of the flotation column 23 and is in communication with its interior. When the flotation device floats all-size ilmenite, the drive motor 27 drives the fourth pulley 26 to rotate, and then the fourth pulley 26 drives the first pulley 12 to rotate through the first belt 25. At this time, the first pulley 12 drives the second pulley 13 and the components inside the bearing block 11 to rotate simultaneously. Then the second pulley 13 drives the third belt to rotate through the second belt 14, and then the third belt drives the blast impeller 17 to rotate through the driving shaft 16. At this time, the blast impeller 17 conveys the gas in the blast hood 19 to the air-gathering hood 21 through the through groove 20, and then the air-gathering hood 21 conveys the gas to the interior of the flotation column 23 through the air duct 22, so as to achieve aeration of the all-size ilmenite being floated, accelerate the speed of gas entering the flotation machine body 1, and avoid the phenomenon that the all-size ilmenite is not completely floated due to low aeration efficiency of the flotation machine body 1.

[0022] It should be noted that, referring to Figure 2 , the flotation column 23 is fixedly connected to the other end of the bearing block 11. The other end of the flotation column 23 is rotatably connected to a guiding impeller 24. When the first pulley 12 rotates, the bottom end of the first pulley 12 drives the guiding impeller 24 at the bottom end of the flotation column 23 to rotate through the components inside the bearing block 11, so as to achieve the guiding of the all-size ilmenite flotation.

[0023] It is worth introducing that, referring to Figure 2 , the first pulley 12 is drivingly connected to a fourth pulley 26 through the first belt 25. The bottom end of the fourth pulley 26 is fixedly connected to a drive motor 27. When the flotation device floats all-size ilmenite, the drive motor 27 drives the fourth pulley 26 to rotate, and then the fourth pulley 26 drives the first pulley 12 to rotate through the first belt 25, so as to achieve the transmission effect.
