[0034] A connecting plate 12 is movably disposed below the positioning plate 10, and the positioning plate 10 and the connecting plate 12 are engaged in abutment. Several arc-shaped plates 13 are perforated on the peripheral wall of the connecting plate 12, with arc-shaped plates 11 and 13 engaging in abutment.

[0036] In using this invention, the flotation tailings of magnesite, carrying foam, enter the defoaming tank 1 through the feed inlet 2. The defoaming paddle 6 rotates at high speed driven by the motor 5, while the rotating rod 4 drives the guide vane 7 to rotate, causing the foam liquid to flow downwards through the guide pipe 8 onto the defoaming paddle 6. During the rotation of the defoaming paddle 6, the paddle generates shearing and impact forces on the foam, causing the foam liquid film to rupture and gas to escape, thus achieving defoaming. The defoamed liquid diffuses through the pipe formed by the combination of arc-shaped plate 11 and arc-shaped plate 13 to the inner wall around the defoaming tank 1, thereby achieving circulation and defoaming. To improve defoaming efficiency, the liquid level sensor 19 monitors the liquid level in real time. When the liquid level reaches the set height, the control signal can adjust the tailings feeding speed to ensure that the defoaming process is carried out within a suitable liquid level range, so that the height of the diversion pipe 8 is below the liquid surface. The defoamed tailings then flow out through the discharge port 3 and enter the subsequent tailings treatment process, such as tailings concentration and dewatering. This defoaming device helps to improve the efficiency and quality of tailings treatment and reduce problems such as equipment blockage and reduced processing capacity caused by excessive foam. It has important application value in the magnesite beneficiation industry.
