[0031] The dispersion mechanism includes a static disk 2 fixedly mounted on the first end of the negative pressure dispersion chamber 1 and a dynamic disk 5 rotatably mounted on the second end of the negative pressure dispersion chamber 1. A static gear ring 3 is provided on the side of the static disk 2 facing the dynamic disk 5, and a dynamic gear ring 6 is provided on the side of the dynamic disk 5 facing the static disk 2. The static gear ring 3 and the dynamic gear ring 6 cooperate with each other. A feed through hole is provided on the static disk 2, and a motor 13 is connected to the dynamic disk 5.

[0032] The feed pipe 8 is connected to the first end of the negative pressure dispersion chamber 1 , and is provided with a first branch pipe 9 for liquid feed and a second branch pipe 10 for powder feed. Both the first branch pipe 9 and the second branch pipe 10 are provided with regulating valves 11 .

[0033] The discharge pipe 12 is connected to the side wall of the negative pressure dispersion chamber 1. Figure 6As shown, a discharge port 121 is provided along the tangential direction of the side wall of the negative pressure dispersion chamber 1, and the discharge pipe 12 is connected to the discharge port 121.

[0034] As a preferred embodiment, the radial clearance between the stationary gear ring 3 and the movable gear ring 5 is not greater than 0.05 mm. Figure 1 and Figure 6 As shown, the radial clearance is a, then a≤0.05mm, so that the powder can be ground more finely.

[0035] As a preferred implementation, Figure 2 and Figure 3 As shown, there are multiple stationary gear rings 3, and the multiple stationary gear rings 3 are coaxially arranged and distributed at intervals in the radial direction.

[0036] As a preferred implementation, the stationary teeth 4 of adjacent stationary gear rings 3 are staggered.

[0037] As a preferred embodiment, the static teeth 4 are in the shape of a helical tooth structure.

[0038] As a preferred implementation, Figure 4 and Figure 5 As shown, there are multiple movable gear rings 6, and the multiple movable gear rings 6 are coaxially arranged and distributed at intervals in the radial direction.

[0039] As a preferred embodiment, the movable teeth of adjacent movable gear rings 6 are radially distributed.

Figure 7 As shown, in the second embodiment, the outermost movable gear ring 6 of the movable plate 5 is arranged on the outer side of the outermost stationary gear ring 3 of the stationary plate 2 .

[0040] As a preferred embodiment, the first end of the negative pressure dispersion chamber 1 is provided with a through hole for the feed pipe 8 to pass through, and the through hole 8 is connected to the feed through hole, so that the powder in the feed pipe 8 can enter the negative pressure dispersion chamber 1 through the feed through hole of the static plate 2.
