The cleanliness of the spinneret hole has an important impact on production and use. If there are many impurities or slurry in the spinneret hole, it cannot be put into production and use normally, or the spinneret hole pass rate does not meet the use requirements during the test, which will cause production abnormalities when it is put into production and use, and needs to be replaced again, which affects production efficiency in the process and causes related energy loss. Therefore, it is particularly important to improve the cleanliness of the spinneret.

[0003] Since the spinneret aperture is very small and difficult to clean, it is difficult to clean it thoroughly by ordinary cleaning methods. In order to clean the spinneret more thoroughly, improve production efficiency and reduce energy consumption, a spinneret boiling and cleaning device is urgently needed. Utility Model Content
