[0003] In the prior art, an arc-shaped baffle movable up and down is arranged at the edge of the circular froth tank, and the froth thickness is adjusted by changing the height of the top of the baffle relative to the top of the froth tank. However, the following problems exist: 1. The froth tank and the baffle are both circular, and the two are connected by slot bolts. It is difficult to accurately align the bolt holes in the circumferential direction during processing and manufacturing. The spacing between the bolt holes is difficult to guarantee, and there is an error. It is difficult to ensure that the cooperation between each bolt and the slot is ideal. 2. Adjusting the relative height of the baffle and the froth tank is complex. Due to the characteristics of the baffle moving up and down along the slot, slight displacement can cause significant changes in concentricity, increase the friction between the baffle and the froth tank, and make the adjustment process not smooth. It is difficult to accurately control the displacement of the baffle, which reduces the accuracy and stability of the adjustment. 3. After adjusting the height of the baffle, tightening the bolt can cause the baffle to displace again due to uneven torque. Therefore, improvement is needed. SUMMARY
