Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In this embodiment: the ilmenite flotation device is mainly divided into three parts: a flotation tank 1, a grouting pipe 29 and a cross frame 16. When the device is working, firstly, the slurry containing ilmenite is input into the flotation tank 1 through the external device and the grouting pipe 29, and then the swing motor 26 and the feeding motor 11 are started. When the external device injects high-speed slurry into the grouting pipe 29, the external air enters the air injection pipe 36 under the action of the fluid pressure difference. At this time, a part of the air enters the mixing cylinder 32 through the branch pipe 1 37 to fully mix with the slurry, and the mixed slurry hits the bottom of the flotation tank 1 at a high speed through the injection cylinder 34 at the bottom. Due to the circulation pressure difference, the slurry inside the flotation tank 1 will enter the injection cylinder 34 again through the stirring port 35 to fully stir and mix with the slurry. Another part of the air is sprayed to the vicinity of the stirring port 35 through the branch pipe 2 38. This design can further increase the slurry flow rate at the stirring port 35, and can also mix and aerate it again before entering the injection cylinder 34. When the swing fan 23 swings counterclockwise to the left, the second driving arm 25 drives the second shift block 21 to the left, and the cross frame 16 and the arc portion 17 swing counterclockwise to the left along the arc seat 9. When the swing fan 23 swings clockwise to the right, the first driving arm 24 drives the first shift block 20 to the right, and the cross frame 16 and the arc portion 17 swing clockwise to the right along the arc seat 9. When the unloading motor 11 drives the two sets of linkage gears 12 to rotate outward, the tipping bucket 10 will transport the foam to the foam discharge trough 2. When the two sets of linkage gears 12 mesh and rotate with each other, the spiral shaft 7 cleans the slag under the drive of the linkage belt 15.

[0030] See attached Figure 1 and attached Figure 3 A foam discharge pipe 3 is provided at the bottom of the foam discharge groove 2, and a control valve 6 is provided at the outlet of the slag discharge pipe 5.

In order to control the opening and closing of the slag discharge pipe 5, a control valve 6 is designed.

[0032] See attached Figure 1 and attached Figure 4 Two sets of mutually meshing linkage gears 12 are rotatably arranged on the front side of the flotation tank 1. A feeding motor 11 is also installed on the front side of the flotation tank 1. The feeding motor 11 is connected to one set of linkage gears 12 through a first belt 13. The linkage gears 12 are connected to the tipping bucket 10 on the same side through a second belt 14.

[0033] In this embodiment, during operation, the flotation ore will adhere to the foam and float on the surface of the slurry. When the unloading motor 11 drives the two sets of linkage gears 12 to rotate outward, the tipping bucket 10 will transport the foam to the foam discharge tank 2.

[0034] See attached Figure 1 and attached Figure 3 -Attached Figure 4 An observation window 8 is provided on the outer wall of the flotation tank 1 , and the spiral shaft 7 is connected to one set of linkage gears 12 through a linkage belt 15 .

[0035] In this embodiment, the slag in the slurry after flotation will accumulate in the sedimentation bin 4. If it is not cleaned in time, it will affect the subsequent flotation work. When the two sets of linkage gears 12 are meshed and rotated with each other, in order to clean the slag through the spiral shaft 7, the spiral shaft 7 is connected to one set of linkage gears 12 through a linkage belt 15.

[0036] See attached Figure 1 -Attached Figure 2 and attached Figure 4 A first shift block 20 and a second shift block 21 cooperating with the swing fan 23 are fixedly arranged on the outer wall of the arc-shaped portion 17; a swing motor 26 is also installed on the outer wall of the flotation tank 1, and a short swing arm 27 is connected to the output end of the swing motor 26, and a long swing arm 28 is movably connected to the end of the short swing arm 27, and the short swing arm 27 is movably connected to the middle part of the swing fan 23 through the long swing arm 28.

[0037] In this embodiment, the swing motor 26 drives the short swing arm 27 to rotate. When the swing fan 23 swings counterclockwise to the left, the second driving arm 25 drives the second shift block 21 to the left, and the cross frame 16 and the arc portion 17 swing counterclockwise to the left along the arc seat 9. When the swing fan 23 swings clockwise to the right, the first driving arm 24 drives the first shift block 20 to the right, and the cross frame 16 and the arc portion 17 swing clockwise to the right along the arc seat 9.

[0038] See attached Figure 2 -Attached Figure 5 A track 18 is arranged on the top of the arc seat 9, and a groove 19 cooperating therewith is opened inside the arc portion 17.

[0039] In this embodiment, when the cross frame 16 swings back and forth along the arc seat 9, in order to further improve the stability during the swinging, a track 18 and a groove 19 structure that cooperate with each other are designed.

[0040] See attached Figure 4 -Attached Figure 6A plurality of gas injection pipes 36 are also provided on the horizontal frame 16 , and a branch pipe 1 37 and a branch pipe 2 38 are provided on the gas injection pipe 36 . The branch pipe 1 37 is connected to the mixing bin 33 , and the outlet end of the branch pipe 2 38 is tilted and faces the stirring port 35 .

[0041] In this embodiment: when the external equipment injects high-speed slurry into the grouting pipe 29, the external air enters the air injection pipe 36 under the action of the fluid pressure difference. At this time, a part of the air enters the mixing barrel 32 through the branch pipe 1 37 to be fully mixed with the slurry, and the mixed slurry hits the bottom of the flotation tank 1 at high speed through the injection barrel 34 at the bottom. Due to the circulation pressure difference, the slurry inside the flotation tank 1 will enter the injection barrel 34 again through the stirring port 35 to be fully stirred and mixed with the slurry. Another part of the air is sprayed to the vicinity of the stirring port 35 through the branch pipe 2 38. This design can further increase the slurry flow rate at the stirring port 35, and can also mix and aerate it again before entering the injection barrel 34.

[0042] See attached Figure 4 -Attached Figure 5 The tops of the grouting pipes 29 are connected to each other through a connecting pipe 39, and the connecting pipe 39 is connected to an external grouting device through a hose.

[0043] In this embodiment, when the cross frame 16 drives the multiple groups of injection cylinders 34 to swing back and forth, in order to ensure that the grouting pipe 29 maintains a communication state with an external device (not shown), it is connected to the grouting device through a hose.

[0044] See attached Figure 1 and attached Figure 4 A grouting pump 30 is also installed on the outer wall of the grouting pipe 29, and a plurality of supporting legs 22 are fixedly arranged at the bottom of the flotation tank 1.

[0045] In this embodiment, in order to ensure that the injection speed of the slurry is increased, thereby further improving the mixing effect with air, a grouting pump 30 is designed.

[0046] Working principle of the present invention: When the device is working, firstly, the slurry containing ilmenite is input into the flotation tank 1 through the external device and the grouting pipe 29, and then the swing motor 26 and the feeding motor 11 are started. When the external device injects high-speed slurry into the grouting pipe 29, the external air enters the air injection pipe 36 under the action of the fluid pressure difference. At this time, a part of the air enters the mixing cylinder 32 through the branch pipe 1 37 to be fully mixed with the slurry, and the mixed slurry hits the bottom of the flotation tank 1 at a high speed through the injection cylinder 34 at the bottom. Due to the circulation pressure difference, the slurry inside the flotation tank 1 will enter the injection cylinder 34 again through the stirring port 35 to be fully stirred and mixed with the slurry. Another part of the air is sprayed to the vicinity of the stirring port 35 through the branch pipe 2 38. This design can further increase the slurry flow rate at the stirring port 35, and can also mix and aerate it again before entering the injection cylinder 34. When the swing fan 23 swings counterclockwise to the left, the second driving arm 25 drives the second shift block 21 to the left, and the cross frame 16 and the arc portion 17 swing counterclockwise to the left along the arc seat 9. When the swing fan 23 swings clockwise to the right, the first driving arm 24 drives the first shift block 20 to the right, and the cross frame 16 and the arc portion 17 swing clockwise to the right along the arc seat 9. When the unloading motor 11 drives the two sets of linkage gears 12 to rotate outward, the tipping bucket 10 will transport the foam to the foam discharge trough 2. When the two sets of linkage gears 12 mesh and rotate with each other, the spiral shaft 7 cleans the slag under the drive of the linkage belt 15.
