AI Technical Summary
In existing agitation devices, the shear heat at the blade tip cannot dissipate in time during the agitation process, resulting in a local temperature rise of 15–20 ℃. High temperature combined with shear will promote micro-hydrolysis of TCP, generating acidic phosphate esters and free cresol, increasing the acid value, turning the color yellow, and corroding the shaft seal.
The system employs a linkage assembly and coating mechanism. Air is discharged through the negative pressure hole inside the high-strength stirring rod to create a negative pressure state. The piston plate and coating layer are used to coat and evaporate the coolant. The movement of the piston plate is automatically adjusted to achieve continuous cooling. At the same time, the anti-sloshing assembly prevents the coolant from sloshing and affecting the stirring stability.
It effectively prevents TCP micro-hydrolysis caused by high-temperature shearing, avoids acid value increase and yellowing, reduces shaft seal corrosion, and improves stirring stability and batch consistency.
