Open your mind and let’s discuss a question
Thread Content
We have an old plant extraction production line; the extraction tanks have a diameter of 4 meters and a height of over 2 meters, with wall thicknesses of only 8 millimeters. No mixing device is installed, but the process requires uniform mixing. Currently, manual air tube stirring and manual turning of the material are being used. Use your imagination to think of other ways to reduce manual labor. (The tank has too large a diameter and too thin walls, resulting in poor mixing.)
Add a stirrer; ensure that the stirrer does not put stress on the device itself, so install a bracket and place the stirrer on it.
Add a ring pipe at the bottom with an opening downward. The mixing state is maintained through the adjustment of air volume and pressure. Add appropriate baffles to the tank wall to improve the flow pattern of the material.

Are baffles on the large-diameter tank walls not very effective? What I plan to do is use compressed air blown in a tangential direction to rotate the liquid material; I’m not sure if that will work.
Is the medium in the extraction tank liquid or solid? Solid particles? This is very important for clearing up doubts! !
Solid-liquid mixture, with solids resembling wood chips (typically with a diameter of 2-7 mm)
Add a return pipeline and a mixer on it; mixing is achieved through reflux, or two layers of air pipes can be installed in the tank with small holes drilled in them to facilitate mixing via aeration.
The opening in the ring tube is for inflating air, while the opening at the bottom is to prevent blockage of the ring tube
If using tangential inlet, it is still recommended to add baffles in order to achieve a stirring effect
