Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a spiral ribbon stirring device. Background Art

[0002] Since conventional agitators produce almost no vertical flow, the mixing effect in the center of the container is poor. This disadvantage is particularly evident when used with high-viscosity fluids. Ribbon agitators can generate a flow that is primarily vertical and horizontal, providing better mixing throughout the container, making them suitable for stirring medium and high viscosity fluids.

[0003] The existing spiral ribbon stirring blades are fixed by multiple sets of bolts on the support rod of the stirring shaft. When the stirring blades are stirred with chemical viscosity fluids for a long time, the connection between the stirring blades is easily corroded and damaged, making it inconvenient, time-consuming and labor-intensive to disassemble and assemble the multiple sets of fixing bolts on the stirring blades. Therefore, we propose a spiral ribbon stirring device. Utility Model Content
