AI Technical Summary
Existing polymer material mixing devices have low stirring efficiency and amplitude, which causes raw materials to easily adhere to the inner wall of the equipment during the mixing process, affecting the mixing effect and material uniformity.
The mixing assembly, including a drive motor, bevel gear transmission, and T-shaped rotating shaft, combined with an arc-shaped fixing rod and spiral blades, is used for staggered and directional mixing of materials inside the reactor, breaking up the hierarchical structure and improving the uniformity of mixing.
It effectively improves mixing uniformity and flowability, reduces material aggregation and sedimentation, enhances reaction rate and efficiency, and facilitates equipment disassembly and cleaning, thereby reducing safety hazards.
