[0049] The working process is as follows:

[0050] S1, in use, the ore pulp is added into the flotation tank 1 and the bubble generating device 2 is started, so that the ore-containing foam appears in the flotation tank 1;

[0051] S2, then the second driving member 31 is started, the second driving member 31 drives the second belt wheel 331 to rotate through the second transmission belt 32, the second belt wheel 331 drives the second connecting frame 34 through the third connecting pipe 33, and the second connecting frame 34 drives the bubble pushing plate 35 to rotate around the third connecting pipe 33;

[0056] S7, at the same time of blowing the airflow, the bubble pushing plate 35 moves to the third connecting pipe 33 in the connecting frame 341 due to gravity, and the airflow blown out from the gas outlet 343 cleans the ore-containing foam attached to the bubble pushing plate 35 during the movement of the bubble pushing plate 35, avoiding the situation that the ore-containing foam attached to the bubble pushing plate 35 causes corrosion or affects the subsequent bubble pushing effect of the bubble pushing plate 35.
