The power is transmitted from the stirring rod 40 to the gear ring 43 through gear 1 41 and gear 2 42, which drives the gear ring 43 to rotate at a slower speed than the stirring rod 40. This drives the scraper 44 to move and scrape off the raw materials adhering to the inner wall of the heat preservation cylinder 21. After the stirring and mixing is completed, the electronically controlled valve of the reactor body 12 can be opened to discharge the corrosion and scale inhibitor inside the reactor body 12.

Then, constant-temperature liquid is introduced through pipe 23 into the sealed jacket formed by insulation cylinder 21, pipe 22, and vessel 12, maintaining the raw materials inside vessel 12 at a constant temperature. To prevent the raw materials from denaturing at high temperatures, the motor 33 and hydraulic cylinder 37 are turned on. The motor 33 provides power, which is transmitted through the reducer 32, pulley 34, and belt 35 to drive the stirring rod 40 to rotate. The hydraulic cylinder 37 provides power to drive the stirring rod 40 to move up and down while rotating.

The power is transmitted from the stirring rod 40 to the gear ring 43 through gear 1 41 and gear 2 42, which drives the gear ring 43 to rotate at a slower speed than the stirring rod 40. This drives the scraper 44 to move and scrape off the raw materials adhering to the inner wall of the insulation cylinder 21. After the stirring and mixing are completed, the electronically controlled valve of the reactor body 12 is opened to discharge the corrosion and scale inhibitor inside the reactor body 12.
