AI Technical Summary
In the existing reaction vessel, during the preparation of trimethylbenzoic acid by stirring, the raw materials tend to settle at the bottom of the vessel, resulting in incomplete reaction and affecting production efficiency.
A stirring assembly including a transmission rod, stirring blades, adjusting screw, and a bottom-turning plate was designed. The transmission rod drives the stirring blades to stir the upper raw materials, while the adjusting screw drives the bottom-turning plate to rise and fall vertically, thereby turning over the raw materials at the bottom of the vessel and preventing sedimentation.
This improved the mixing efficiency of raw materials, ensuring thorough mixing and enhancing the production efficiency of trimethylbenzoic acid.
