An air duct is arranged inside the first material frame, and a blower is installed on one side outside the first material frame. The air outlet of the blower is communicated with the air duct; a second material frame is integrally formed at the bottom of the first material frame. One end of the second material frame is connected with a connecting pipe, and a waste discharge pipe is connected to the bottom of the connecting pipe. In the utility model, the cylinder drives the connecting plate and the limiting frame to move left and right reciprocally as a whole, so that the water flow in the first material frame and the second material frame can shake rapidly. At the same time, the blowing position of the air guide hose will also be changed, thereby further improving the aeration effect of the device to improve the flotation efficiency of copper ore; the funnel-shaped second material frame can accumulate waste residues at its bottom. Under the action of the connecting pipe, the waste discharge pipe, the motor and the auger, the convenience of discharging the waste residues can be improved.

[0028] In this embodiment, during aeration, through the arranged driving motor 3, when in use, it drives the aeration component 4 to rotate in the flotation barrel 1, and at the same time injects gas into the flotation barrel. When injecting gas, it can fully inject gas into the flotation barrel 1 to prevent dead angles, and at the same time stir the water, which is convenient for the foaming agent to be fully fused with the water during flotation, more effectively and quickly generate bubbles, increasing the flotation efficiency. At the same time, during stirring, the aeration component 4 will not be damaged due to long-term rotation, thus increasing the service life during aeration.

[0029] Referring to Figures 1 - 3 , the aeration component 4 includes a notch 6. The notch 6 is opened in the middle of the top side of the bearing plate 2. The width of the notch 6 is smaller than the width of the output end face of the driving motor 3. A sealing cover 7 is fixedly installed in the notch 6. The bottom side of the sealing cover 7 is hermetically connected to the bottom side of the notch 6 through a sealing ring. Wherein the output shaft of the driving motor 3 passes through the sealing cover 7 and extends into the flotation barrel 1 and is horizontally installed with a connecting shaft 8. And the output shaft of the driving motor 3 is hermetically connected to the sealing cover 7 through a dynamic sealing ring. The output shaft of the driving motor 3 is installed with a hollow shaft 9 through the connecting shaft 8.
