Description

Technical Field

[0001] The utility model relates to the field of polymerization reaction accessory equipment, in particular to a co-directional parallel three-axis differential transmission mechanism. Background Art

[0002] Currently, discontinuous tank reactors are commonly used in polymer polymerization and high-solvent devolatilization, with some using continuous tubular reactors (which have process limitations). High-solvent devolatilization in solution polymerization utilizes a wet process or multiple dry devolatilization units in series, resulting in lengthy processes and high overall energy consumption.

[0003] With the continuous development of new materials in the petrochemical and medical chemical industries, especially those requiring continuous polymerization reactions and high-solvent devolatilization, horizontal biaxial continuous polymerization and high-solvent devolatilization equipment has recently been developed and applied. However, factors such as the equipment's volume ratio, heat exchange area, and reaction time limit its application to materials requiring short polymerization times, low production capacities, or processes requiring low-volume solvent devolatilization. This limits the promotion and application of horizontal reactors in high-volume projects.

[0004] To address the issues of smaller working volume and heat exchange area in dual-axis reactors, our company has developed a new triaxial reactor. Compared to conventional dual-axis reactors, this new triaxial reactor not only offers the same continuous production method and self-cleaning capabilities, but also boasts a larger working volume and heat exchange area under the same rotor specifications. This allows the equipment's aspect ratio to be reduced while increasing the working volume and heat exchange area, thereby reducing the design and processing difficulty of large-scale equipment. Furthermore, the additional axis provides an additional set of meshing areas, resulting in superior interface renewal and mixing and dispersion capabilities, further improving reaction or devolatilization efficiency. The innovatively optimized new large-diameter triaxial reactor is a more efficient, high-capacity continuous polymerization reaction and high-solvent devolatilization equipment, with broad application prospects in related industries such as polymer synthesis, chemical synthesis, pharmaceuticals, and food processing. The core technology of the triaxial reactor is the co-directional, differentially rotating rotors, so a high-torque transmission system that provides rotor rotation has become a key research and development area.
