The rotation of the stirring shaft 3 will drive the stirring blades 15 to stir the silica sol. During the distillation process, the arc scraper 5 installed at the end of the fixed rod 4 will continue to contact the inner wall of the distillation kettle body 1. The arc scraper 5 will push and clean the silica sol material stuck on the inner wall of the distillation kettle body 1 to prevent the silica sol from excessively sticking to the inner wall of the distillation kettle body 1 and causing a decrease in the output of the distillation product. The rotation speed of the stirring shaft 3 is accelerated, and the centrifugal force of the movable rod 7 and the arc brush plate 8 will drive the arc brush plate 8 to stick to the inner wall of the distillation kettle body 1.
