Description

Technical Field

[0001] The utility model relates to the field of chitosan fiber preparation, and more specifically to a dissolving kettle for preparing chitosan fiber. Background Art

[0002] To prepare chitosan fibers, the chitosan raw material must first be dissolved in an appropriate solvent to form a chitosan solution with a certain degree of fluidity and plasticity. This ensures smooth processing, such as spinning. As the primary equipment for dissolving chitosan, the dissolving vessel plays a key role in the chitosan fiber preparation process.

[0003] In existing dissolving kettles, the drive motor coupling is often exposed to the elements without proper shielding or protection. This can lead to operators accidentally touching the coupling during operation, potentially causing safety incidents. Some welding kettles use nets or straps to shield the coupling, but this is cumbersome and unsightly. While some shielding mechanisms can provide adequate protection, they are complex to disassemble and inconvenient when inspecting and maintaining the coupling. Utility Model Content
