The linkage ring 1646 is provided with teeth, which can be engaged with the rotating disk 3 1510. When the rotating disk 3 1510 rotates, the linkage ring 1646 can be pulled to rotate, thereby pulling the stirring piece 1642 to rotate, and the picking piece 1644 can scrape up the calcium zincate on the screening net 17. The scraped calcium zincate can be thrown into the stirring piece 1642 with the rotation of the stirring part 164, and gathered in the corresponding blocking piece 1645 area. While the blocking plate 1645 rotates to the top, the gathered calcium zincate falls onto the dispersion unit 2 163 and is then processed, so that the calcium zincate is repeatedly crushed and dispersed, thereby achieving the required calcium zincate particle size. A disc 16410 is installed at one end of the stirring plate 1642 close to the linkage ring 1646, and a through hole 1647 is reserved in the central area of ​​the disc 16410. The rotating rod 1633 of the dispersion unit 2 163 protrudes from the through hole 1647.

[0031] During use, after calcium zincate is put into the injection shell 12, it moves to the receiving chamber through the shielding portion 13 for dispersion. When the motor 152 is working, it pulls the power member 153 to rotate, and the power member 153 pulls the linkage member 155 to rotate through the linkage portion 154, and the linkage member 155 pulls the rotating disk 156 to rotate, so that the rotating disk 156 pulls the rotating disk 2 157 to rotate counterclockwise, and the linkage member 2 158 also rotates with the rotation of the rotating disk 156, and pulls the linkage member 3 159 to rotate through the linkage portion 2 151, and the linkage member 156 pulls the rotating disk 2 157 to rotate counterclockwise. The moving part 3 159 pulls the rotating disk 3 1510 to rotate, so that the rotating rolling dispersion module 1 and the rotating rolling dispersion module 2 rotate in different directions. The rotating disk 3 1510 pulls the stirring part 164 to rotate, and the dispersion unit 162 assembled on the stirring part 164 rotates accordingly. The dispersion unit 162 cuts the calcium zincate in the input hole 135 area of ​​the shielding part 13, so that the calcium zincate can be cut for the first time and the calcium zincate can be prevented from being blocked in the input hole 135 area. The rotating rolling dispersion module 1 and the rotating rolling dispersion module 2 strengthen the zincate. The calcium zincate that meets the treatment standard will pass through the screening net 17 and be discharged from the discharge channel 142, while the calcium zincate that does not meet the treatment standard will be scraped up by the picking piece 1644 and thrown into the stirring piece 1642 as the stirring part 164 rotates, and is gathered in the corresponding blocking piece 1645 area. As the stirring part 164 rotates, while the blocking piece 1645 rotates to the top, the gathered calcium zincate falls onto the dispersion unit 2 163 and is then processed. In this way, the calcium zincate is repeatedly dispersed to achieve the required size. Then The calcium zincate falling from the breaking part 16 and the discharge channel 142 falls onto the screen 118. The elastic cloth 1110 is installed to ensure that the calcium zincate will not float between the outer shell 111 and the screening shell 113. The telescopic rod 116 is operated, and the movable end of the telescopic rod 116 pulls the sheet 117 to move. The sheet 117 pulls the arc bar 114 to swing, so that the calcium zincate falling onto the screen 118 is pulled back and forth, which is helpful for the screening of the calcium zincate and the deeper classification of the calcium zincate with different particle sizes, and then it can be taken out from the screening shell 113.
