Description

Technical Field

[0001] This utility model relates to the field of stirring structure technology, and in particular to a stirring structure for a reaction vessel during the production of PVB resin powder. Background Technology

[0002] Most existing reactors with stirring structures use a fixed structure, which limits the stirring effect of the reactor's rotation and results in limited stirring efficiency.

[0003] A Chinese patent discloses a "reaction vessel stirring structure" (application number CN202420116524.6). Through the meshing of a central gear, micro gears, and a fixed gear ring, the spiral stirring blades can achieve both circumferential and rotational movement, resulting in more thorough mixing of chemical raw materials inside the reaction vessel and a smaller dead zone. The filter plate effectively removes impurities generated during the reaction process. Furthermore, the cleaning scraper, along with protrusions and a vibration spring, causes intermittent vibration of the filter plate, preventing clogging of the through-holes and improving filtration efficiency. However, this reaction vessel structure lacks multi-dimensional rotation capabilities, limiting its stirring efficiency. Utility Model Content
