Description

Technical Field

[0001] This utility model relates to the field of melt filter technology, specifically a textile melt filter. Background Technology

[0002] Textile melt filters are devices used in the textile industry to filter polymer melts. In the production of synthetic fibers, polymers such as polyester (PET) and polyamide (PA) need to be heated and melted into a molten state before spinning. However, during this process, the melt may contain impurities, such as incompletely melted polymer particles, catalyst residues, and dust. The function of a textile melt filter is to remove these impurities through a filter medium, ensuring the purity of the melt and thus improving the quality of spinning and the performance of the fibers.

[0003] Chinese patent (authorization announcement number: CN2370939Y, authorization announcement date: March 29, 2000) discloses a melt filter. The patent is characterized by a housing containing several filter elements, each filter element housing a filter cartridge, an operating mechanism on the housing, and several pressure caps on the housing for filter cartridge replacement. This utility model features a simple structure, reliable sealing, multiple position switching capabilities, and a long maintenance cycle, making it an ideal device for filtering polymer melts.

[0004] Existing melt filters are inconvenient to clean and maintain. Cleaning and maintenance require replacing the filter element, which requires a lot of manpower to disassemble and clean. In addition, the traditional filter element structure is relatively fixed and not easy to disassemble, making it inconvenient to replace the filter element in a timely manner. To address this, we propose a textile melt filter. Utility Model Content

Then, the third motor 84 drives the flipping shaft 85 to rotate, thus flipping the filter mechanism 5 clamped between the moving rollers 89. Then, the fourth motor 88 drives the moving rollers 89 to rotate, thus raising and lowering the filter mechanism 5, thus facilitating its further movement above the cleaning nozzle 4, so that the filter element housing 52 can be sprayed with water for cleaning in all directions through the cleaning nozzle 4. This allows one filter mechanism 5 to operate while the other filter mechanism 5 is automatically maintained, saving manpower and improving production efficiency.
