AI Technical Summary
In existing esterification reactors, the stirring range is small when mixing materials and catalysts, which results in insufficient contact between the upper material and the catalyst, affecting the reaction efficiency.
It adopts a multi-layer stirring structure, including a rotating shaft, a support plate, a connecting column and a horizontal shaft. The drive assembly drives multiple stirring blades to perform compound motion, increasing the stirring range and tumbling effect.
This ensures thorough mixing of materials and catalyst, improving reaction efficiency and avoiding efficiency loss due to uneven mixing.
