AI Technical Summary
The intermediate bearing of the stirring shaft in large fermenters is prone to wear and misalignment, affecting the stirring effect, and existing technologies are unable to effectively solve this problem.
A clean intermediate bearing structure for large fermenters is designed, including a coupling structure, a support assembly, and a sealing assembly. An adjustable clamping mechanism and a support rod are used to achieve stable connection and sealing of the bushing through the cooperation of a guide column and a nut. The length of the support rod is adjustable to adapt to fermenters with different inner diameters.
It improves the stability and sealing effect of the bearing, ensures the stable operation of the stirring shaft, reduces wear, facilitates maintenance, adapts to the needs of fermenters with different inner diameters, and enhances the cleanliness and service life of the equipment.
