[0027] The liquid spraying assembly 5 includes a stirring shaft 52 which is inserted and arranged at the center of the cylinder cover 3, and the stirring shaft 52 is rotatably installed on the cylinder cover 3 through a bearing. A driving structure 51 is installed on the top of the cylinder cover 3, and the driving structure 51 is used to drive the stirring shaft 52 to rotate. A row of discharge holes are provided on both sides of the outer wall of the stirring shaft 52, and a nozzle component 53 is installed at the position of the stirring shaft 52 facing the discharge hole. A material channel connected to the discharge hole is provided on the top of the stirring shaft 52.
[0028] The outer wall of the stirring shaft 52 and below each nozzle 53 are sleeved with stirring blades A54 , and the bottom of the stirring shaft 52 is installed with stirring blades B55 .
[0029] The nozzle component 53 includes a liquid outlet pipe 531 welded to the stirring shaft 52, a one-way valve 532 is installed at the discharge end of the liquid outlet pipe 531, a nozzle seat 534 is installed at the discharge port of the one-way valve 532, and spray holes 533 are opened through the four sides of the arc-shaped outer wall of the nozzle seat 534 and the center of the outer side of the nozzle seat 534.
[0030] The driving structure 51 includes a driving motor 511 installed on the top of the barrel cover 3 . A driving gear 513 is installed on the driving end of the driving motor 511 . A transmission gear 512 meshing with the driving gear 513 is sleeved on the outer wall surface of the stirring shaft 52 .
[0031] When adding acid and alkaline solutions to the inside of the regulating cylinder 1, the solutions directly enter the material channel inside the stirring shaft 52 and are dispersed into the inside of each nozzle component 53. The nozzle components 53 are vertically distributed and spray the acid and alkaline solutions outward while rotating, which is conducive to making the acid and alkaline distribution inside the regulating cylinder 1 more comprehensive and uniform.
