Detailed Description

As shown in fig. 1 to 6, the returning slurry is impacted when it is returned to the reaction tank 1 through the return pipe 2, resulting in a large amount of foam. Therefore, an inverted cup body 3 can be arranged around the return pipe 2, the inverted cup body 3 is integrally cup-shaped and is inverted around the return pipe 2 by taking the return pipe 2 as a center. The depth of the pouring cup body 3 is determined according to the liquid level height of the return material in the reaction tank 1, and the lower part of the pouring cup body 3 is ensured to extend below the liquid level. The inverted cup body 3 can be fixed through a bracket and can be adjusted relatively. A limiting ring can be formed by the inverted cup body 3, and foam formed by the return pipe 2 is gathered in the limiting ring.

The lower end of the inverted cup body 3 is provided with a floating plate 4 in a sliding manner, the floating plate 4 comprises a plate body 4-1, the lower end of the plate body 4-1 is provided with a conical part 4-2, the edge of the plate body 4-1 is provided with a lantern ring 4-3, the lantern ring 4-3 penetrates through the inverted cup body 3, and the outer end of the lantern ring is connected with a plurality of floating balls 4-4. A plurality of limiting blocks 13 are circumferentially arranged on the lantern ring 4-3, and the limiting blocks 13 penetrate through clamping grooves 14 on the inverted cup body 3 and are connected with the plate body 4-1.

The floating ball 4-4 is upward and higher than the plate body 4-1, so that the plate body 4-1 and the conical part 4-2 are partially submerged in water, and the floating plate 4 is driven to fluctuate along with the change of the liquid level. The provision of the tapered portion 4-2 contributes to further enhancing foam concentration. The limiting block 13 is favorable for the floating plate 4 to move directionally along the inverted cup body 3.
