Abstract
The invention relates to a bottom aeration system of a flotation machine, which comprises: the aeration pipe is U-shaped, has a lower height at one end and enters the impeller cavity from the bottom of the flotation machine tank body; the other end is higher than the liquid level of the flotation machine; the regulating valve is used for regulating the air quantity of the gas in the gas-filled pipe and controlling the switch, is arranged at the higher end of the gas-filled pipe and is higher than the liquid level of the flotation machine; and the non-return device is arranged at the upper part of the lower end of the gas charging pipe, allows gas to pass through the gas charging pipe outwards, and does not allow ore pulp to pass through the gas charging pipe inwards. When the invention is used, air directly enters the impeller cavity through the inflation pipeline without passing through the bearing body, and the sealing element in the bearing body only has the functions of oil sealing and dust prevention without preventing the leakage of pressurized air, thereby greatly reducing the sealing difficulty between the bearing body and the main shaft and improving the operation reliability of equipment. Meanwhile, a hollow main shaft is not needed, the diameter of the main shaft, a bearing, a sealing element and a bearing body can be greatly reduced, and the processing difficulty and the manufacturing cost of equipment are greatly reduced.
