Description

Technical Field

[0001] This utility model relates to an auxiliary equipment for textile equipment, and more particularly to a TEG automatic cleaning furnace for cleaning spinnerets. Background Technology

[0002] In the textile and chemical fiber production process, spinnerets need to be cleaned regularly to ensure the quality of the produced fibers. Current cleaning processes generally include triethylene glycol (TEG) cleaning, water washing, alkaline washing, ultrasonic cleaning, bubbling testing, and preheating and drying. TEG cleaning furnaces are used for TEG cleaning, leveraging the dissolving and cleaning capabilities of TEG to clean various industrial equipment and materials, such as chemical fiber machinery, spinnerets, and screw dies. However, existing TEG cleaning furnaces have low automation levels. When loading and unloading spinnerets in batches, manual handling and stacking are required, which is not only labor-intensive and resource-intensive but also inefficient. Therefore, it is necessary to design an automated TEG cleaning furnace for spinnerets that can enhance the automation of the TEG cleaning process, reduce manual intervention, and effectively improve cleaning efficiency.
