[0002] The working principle of a flotation machine is based on the difference in contact and adhesion between mineral particles and air bubbles in the flotation cell. In the flotation machine, the slurry treated with reagents is agitated and aerated, causing some mineral particles to selectively adhere to the air bubbles, float to the surface of the slurry, and be scraped off to form a froth product, while the rest remain in the slurry, thus achieving the purpose of separating minerals.

[0003] The power consumption of a flotation machine is affected by a combination of factors. Some advanced flotation machines can reduce power consumption by optimizing their structure and improving equipment efficiency; for example, the power consumption of some flotation machines can be less than [amount missing].

[0004] The power consumption is 1.5 kW·h / t coal (including the power consumption of auxiliary equipment), while the power consumption of traditional flotation machines may be higher. Utility Model Content

The power unit is connected to the flotation column 2 via a transmission connection. The flotation column 2 includes a feed pipe 21, a bearing 22, an impeller 23, a power wheel 24, and an energy-saving device 25. One end of the bearing 22 is connected to the power wheel 24, and the other end passes through the feed pipe 21 and is connected to the impeller 23. The energy-saving device 25 is connected to... One end of the feed pipe 21 is connected to the bearing 22; the energy-saving device 25 includes an upper housing 26, a lower housing 27, a rotating plate 28, a sealing ring 29, a power blade 210, an air inlet 212, and an air outlet 213. The upper housing 26 and the lower housing 27 are fastened together. The sealing ring 29 is disposed between the upper housing 26 and the lower housing 27. Both the upper housing 26 and the lower housing 27 have annular semi-circular grooves. The rotating plate 28 is connected to the bearing 22 and disposed between the upper housing 26 and the lower housing 27. Several blades are used. The power blade 210 is connected to the circumferential surface of the rotating plate 28 and is disposed in an annular semi-circular groove. The upper housing 26 and the lower housing 27 respectively have an air inlet duct 212 and an air outlet duct 213 communicating with the annular semi-circular groove. Air pipe connectors 211 are connected to both the air inlet duct 212 and the air outlet duct 213. Airtight bearings are connected between the upper housing 26 and the lower housing 27 and the bearing 22.

The power blade 210 drives the rotating plate 28, which in turn drives the bearing 22 to rotate, thereby reducing the power required for the power wheel 24 to drive the bearing 22. The gas is then discharged through the outlet duct 213 and enters through the connecting hose. The gas is introduced into the flotation column 2 through the gas outlet pipe and mixed with the slurry for foaming.

The gap between the upper and lower sides of the rotating plate 28 and the upper shell 26 and lower shell 27 is controlled between 0.01mm and 0.05mm to prevent a large amount of gas from flowing out through the gap and reduce the speed of the gas-driven power blades 210. The gas is evenly introduced into the annular semi-circular groove through several air inlets 212 and then discharged through the air outlet 213, so that the power blades 210 are evenly thrust by the gas.
