Description
Technical Field
The invention belongs to the technical field of synthetic fiber production equipment, and particularly relates to a U-shaped annular air blast cooling device for short fiber melt spinning.
Background
Typical examples of the melt spinning of the staple fibers are spun polyphenylene sulfide staple fibers (abbreviated as PPS in English) which are suitable for use in high temperature environments because they have high strength, high temperature resistance and excellent flame retarding effects. However, the polyphenylene sulfide staple fiber is critical to the process requirements during the production process, and specifically, the cooling effect, such as the uniformity of air-blown cooling, is extremely strict after the filaments are extruded from the spinneret orifices on the spinneret.
At present, the air cooling systems used for the polyphenylene sulfide melt-spun staple fibers are circular air-blowing cooling systems, and specific structures can be seen in the following patent documents without limitation: CN202925169U (circular air blast cooling device), CN103820868a (a circular air blast device for producing ultra-fine denier, high quality spinning), CN203923476U (a circular air blast cooling device), CN202809026U (a novel circular air blast device), CN105177738B (circular air blast cooling device for melt spinning), CN106048753a (a central circular air blast device for melt spinning) and CN106192029B (gradient circular air blast cooling device for ultra-high speed spinning of polylactic acid short fiber), and the like.
As is clear from a reading of patent documents not limited to the above, during the circular blowing, cooling air is blown perpendicularly to the filaments from the periphery of the disk-shaped spinneret plate, and the filaments are cooled to form fibers, so that the filaments are prevented from being bonded to each other.
In recent years, as spinning productivity increases, the diameter of the spinneret plate used becomes larger and larger, and the annular air blast cooling device in the prior art including the above-mentioned patents is severely exposed to the shortage that the uniform air blast cooling effect is obtained for the filaments located in the central region of the spinneret plate and the edge region of the spinneret plate, that is, the deviation of the cooling uniformity between the filaments located in the middle of the spinneret plate and the filaments located at the edge of the spinneret plate increases with the increase of the diameter of the spinneret plate, thereby affecting the quality of the fibers. Therefore, the technical solution to be described below is to create a reasonable balance between increasing the diameter of the spinneret and ensuring that the filaments coming out of the spinneret are uniformly cooled.
