[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0018] according to Figure 1 、 2 As shown in Figure 3, this embodiment proposes a flotation device for mineral processing, including a box body 1, a fixed frame 2 and a hollow shaft 3. The top of the box body 1 is fixedly connected to the fixed frame 2, and one side of the fixed frame 2 is rotatably connected to the hollow shaft 3. The hollow shaft 3 is provided with a stirring mechanism, the outer side of the box body 1 is provided with an air filling mechanism, and one side of the bottom of the box body 1 is provided with a stagnation mechanism. A storage bin 6 is fixedly connected to one side of the box body 1, and the ground ore is poured into the interior of the box body 1, and then the regulator, collector and other reagents are poured into the box body. 1, the stirring mechanism stirs the ore and the reagent to form a vortex and mix them to form a slurry, and the inflation mechanism delivers air into the slurry, so that bubbles are generated in the slurry. The useful mineral particles come into contact with the bubbles and adhere to the surface of the bubbles. Since the useful minerals have poor adhesion, they easily form buoyancy with the bubbles, thereby floating to the upper part of the box 1 and then flowing into the storage bin 6. The waste rock particles, due to their strong adhesion, cannot combine with the bubbles and sink to the bottom of the flotation tank and are discharged to the outside through the stagnation mechanism.

[0019] The stirring mechanism includes a vent cylinder 4, an exhaust port 5, a pulley 11, a No. 1 motor 12 and a belt 13. The bottom end of the hollow shaft 3 is fixedly connected to the vent cylinder 4, and the bottom end of the vent cylinder 4 is fixedly connected to the exhaust port 5. One side of the fixed frame 2 is fixedly installed with a No. 1 motor 12. The output end of the No. 1 motor 12 is fixedly connected to the top end of the hollow shaft 3 with a pulley 11. The two pulleys 11 are connected to each other by a belt 13. The No. 1 motor 12 can drive the pulley 11 at its output end to rotate. The two pulleys 11 are connected by a belt 13, and the other pulley 11 is connected to the top end of the hollow shaft 3, so that the No. 1 motor 12 can drive the hollow shaft 3 to rotate on the fixed frame 2. The hollow shaft 3 is connected to the exhaust port 5 through the vent cylinder 4, so as to drive the exhaust port 5 to rotate at the bottom of the box body 1, thereby forming a vortex at the bottom of the box body 1, and then the ore and the reagent are mixed with each other from bottom to top to form a slurry.

[0020] The inflation mechanism includes a fan 8, an air pipe 9 and a filter element 10. The fan 8 is installed on the outside of the box body 1.

[0022] The fan 8 cooperates with the air pipe 9 to transport air into the interior of the hollow shaft 3. The hollow shaft 3 then transports the air into the vent 4 and sprays it into the interior of the slurry through the exhaust port 7, so that multiple bubbles are formed on the top of the slurry. The filter element 10 and the permeable membrane both play an isolating role, preventing dust in the air from entering the interior of the device, and preventing the slurry from invading the interior of the exhaust port 7 and causing blockage.

[0023] A slope is provided on one side of the box body 1, one end of the slope is in contact with the storage bin 6, and a scraper mechanism is provided above the slope, which includes a rotating shaft 14, a scraper 15 and a No. 2 motor 16.

One side of the scraper 15 is in contact with the slope, and a No. 2 motor 16 is installed on the outside of the box body 1. The output end of the No. 2 motor 16 is fixedly connected to one end of the rotating shaft 14. The liquid level at the top of the slurry is parallel to the height of the slope. The output end of the No. 2 motor 16 can drive the rotating shaft 14 to rotate, and the scraper 15 is fixed to the rotating shaft 14 as a whole. The No. 2 motor 16 can drive the scraper 15 to rotate, and the useful minerals floating on the slope are moved to the inside of the storage bin 6.

[0024] The sludge removal mechanism includes a pump body 17 and a discharge pipe 18. The pump body 17 is installed on one side of the bottom of the box body 1. The input end of the pump body 17 is connected to one side of the bottom of the box body 1, and the output end of the pump body 17 is connected to the discharge pipe 18. The pump body 17 and the discharge pipe 18 cooperate to generate suction to extract the waste rock and slurry remaining at the bottom of the box body 1 to the outside of the box body 1.

[0025] In this mineral processing flotation device, a No. 1 motor 12 can drive a pulley 11 at its output end to rotate. The two pulleys 11 are connected by a belt 13, and the other pulley 11 is connected to the top of the hollow shaft 3, so that the No. 1 motor 12 can drive the hollow shaft 3 to rotate on the fixed frame 2. The hollow shaft 3 is connected to the exhaust port 5 through the vent 4 to drive the exhaust port 5 to rotate at the bottom of the box 1, thereby forming a vortex at the bottom of the box 1, and then causing the ore and reagent to mix with each other from bottom to top to form a slurry.
