Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to a stirring device for a bio-based dispersant. Background Technology

[0002] In the field of bio-based materials, the efficient preparation of dispersants plays a crucial role in product performance. In the production of bio-based dispersants, traditional single-axis stirring blades can only form a local flow field. Due to the high viscosity of bio-based dispersants, agglomeration is prone to occur, resulting in uneven particle size distribution, weak axial mixing ability, and large differences in material residence time. This affects the uniform shearing and dispersion effect of the dispersant molecular chains. Bio-based materials are sensitive to temperature and are prone to overheating, leading to material denaturation. After solidification, bio-based dispersants have strong adhesion, and residues on the inner wall of traditional stirring devices are difficult to remove, reducing production efficiency. Existing devices cannot achieve selective discharge of particle size, and the finished dispersant often contains undispersed large particles >100μm, requiring additional sieving processes and increasing production costs.

[0003] Therefore, to address the above issues, a graded discharge system and a synergistic design of efficient stirring and heat exchange are used to achieve high-quality, low-energy preparation of bio-based dispersants, meeting the production needs of environmentally friendly materials.
