Figure 3 for Figure 1 Enlarged view at point A. Figure 4 This is a schematic diagram of the main structure of the grid bars in the water turbulence mechanism of the air flotation machine of the present invention. Figures 1 to 4 As shown, the water turbulence distribution mechanism includes a support frame 4 and a turbulence fence 5. The support frame 4 is threadedly connected to the bottom of the traveling frame 3 near the end of the traveling direction. Exemplarily, a positioning hole plate is provided on the surface of the traveling frame 3 near the traveling direction. Bolt studs are welded to the top of the support frame 4, and the support frame 4 is threadedly connected to the positioning hole plate via the bolt studs. The turbulence fence 5 is clamped to the support frame 4 to facilitate disassembly and cleaning of the turbulence fence 5. The turbulence fence 5 is provided with a bar group 51, which is composed of a plurality of parallel bars 511. Exemplarily, the bar group 51 also includes a plurality of support bars 512. The plurality of parallel bars 511 are welded longitudinally at intervals to the surface of the support bars 512 at the end away from the traveling direction. The turbulence fence 5 is clamped to the support frame 4 via the support bars 512. The bars 511 are provided with a plurality of hole groups 5113. The hole groups 5113 are composed of a plurality of holes 51131 spaced longitudinally along the bars 511.

[0030] like Figures 1-2As shown, further, the water distribution turbulence mechanism of the flotation machine also includes a clean water baffle frame 6, which is welded to the end of the support frame 4 away from the walking direction, and the water distribution pipe 2 extends into the clean water baffle frame 6. Exemplarily, the clean water baffle frame 6 includes a first baffle 61, a second baffle 62, a third baffle 63 and a fourth baffle 64. The first baffle 61 is suspended on the bottom surface of the flotation pool 1. The second baffle 62 is an arc-shaped baffle with the center of the circle being the center of the flotation pool 1. It is arranged at the top of the first baffle 61, close to the center of the flotation pool 1. The third baffle 63 is an arc-shaped baffle with the center of the circle being the center of the flotation pool 1. It is arranged at the top of the first baffle 61, close to the edge of the flotation pool 1. The fourth baffle 64 is arranged at the top of the first baffle 61, on the outside of the water distribution pipe 2 away from the walking direction.

If the water distribution turbulence mechanism of the flotation machine is used in the textile and printing and dyeing fields, the textile fibers can pass through the plurality of hole groups 5113 formed on the bars 511, which can reduce the textile fibers from hooking on the turbulence grid 5, reduce the equipment failure rate, and improve work efficiency.
