[0022] The crushing assembly includes a first rotating rod 17 rotatably mounted on a support rod 5 via a bearing. The lower end of the first rotating rod 17 extends to the lower interior of the crushing cylinder 13. Crushing blades 18 are fixed at equal intervals on the bottom outer wall of the first rotating rod 17.

A synchronous belt 7 connects the first synchronous pulley 8, the second synchronous pulley 6 and the third synchronous pulley 4.

[0025] The first servo motor 3 drives the third synchronous pulley 4 to rotate, and then transmits the power to the first rotating rod 17 and the second rotating rod 11 through the synchronous belt 7, so that the first rotating rod 17 and the second rotating rod 11 rotate, and the powdered additive is put into the crushing cylinder 13. The first rotating rod 17 drives the crushing blade 18 to rotate and break up the lumps in the powdered additive, ensuring that the additive falling into the mixing tank 2 is all in powder form, so as to improve the rapid and uniform mixing of the additive with the fluid in the mixing tank 2.

A storage bin 9 is fixed to the top of the end of the conveying pipe 10 near the second servo motor 14.

[0027] The storage bin 9 is used to store powdered additives. The screw conveyor 16 is driven to rotate by the second servo motor 14, which can stably transport the powdered additives in the storage bin 9 to the crushing cylinder 13, so as to achieve uniform addition of additives.
