AI Technical Summary
In existing batch-type polyester thickening mixing tanks, the material cannot adhere tightly to the tank wall during the mixing process, resulting in poor mass and heat transfer. Furthermore, the material tends to accumulate on the mixing shaft, affecting the mixing effect.
A stirring shaft structure with baffles, an upper spiral plate, a lower spiral plate, and an anchor-type stirring paddle was designed to allow the material to be scraped and scraped onto the vessel wall and in close contact with the heat source. The baffles disperse the fluid and prevent the material from accumulating on the stirring shaft.
It improves mass and heat transfer efficiency, prevents material adhesion, ensures stirring effect, promotes the release of light components and allows materials to fall back to the bottom of the vessel, thus enhancing the overall performance of the batch-type polyester thickening stirring vessel.
