AI Technical Summary
When the existing ring hair dryer is produced above 300D varieties, the wire strips are unevenly cooled, resulting in poor drying of the original wire strips, more hairs, and low AA rate, which affects the production quality.
The design is to have air outlets arranged on the upper part of the inner cylinder and a conical air guide on the upper part of the outer cylinder. The angle between the busbar and the axis of the conical air guide is 4° to 6°, which increases the uniformity of air outlets. A filter is installed on the inner side of the inner cylinder to improve the purity of air outlets and keep the equipment structure unchanged.
It achieves the improvement of air uniformity without changing the equipment structure, improves the cooling effect and quality of the original silk strips, reduces the wool silk, and the AA rate reaches 98%.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical fiber spinning equipment, in particular to an improved structure of a ring blowing cylinder. Background Art
[0002] In the production of chemical fiber spinning, when the filament is just extruded from the spinneret, the temperature of the filament is relatively high at this time and its structure is still unstable. For the newly formed filament fiber, the cooling step is a key process link to ensure its excellent performance, and the ring blowing cylinder cooling system is the equipment used in this key process link. Through the high-speed air flow blown out from the ring blowing cylinder, the temperature of the newly formed fiber is quickly reduced to room temperature, and the structure and performance of the fiber are stabilized. The existing ring blowing cylinder adopts a parallel design of the inner and outer cylinders. When producing products below 200D, since the air volume required for filament cooling is not large, the design margin of the air volume of the ring blowing cylinder is relatively large, and the cooling requirements of the process can be fully met during production, and the product quality is stable. However, when producing products above 300D, due to the uneven air outlet speed of the inner cylinder of the ring blowing cylinder, the produced raw filament has large dry difference and many hairiness, and the AA rate of the raw filament has never been able to reach 97%, and the post-processing state is not ideal, and the AA rate of the post-processed finished product has been below 90%. Therefore, in order to avoid the disadvantages existing in the prior art, it is necessary to make improvements to the prior art. Summary of the Utility Model
