Description

Technical Field

[0001] The invention relates to the technical field of hank drying, and in particular to a multi-layer hank drying system with high efficiency and low energy consumption. Background Art

[0002] Drying is an essential step in the weaving and dyeing process. The existing hank yarn dryer is usually a continuous hank yarn dryer, which includes a transport mechanism and a drying mechanism, wherein the drying mechanism includes a housing and a heating tube arranged in the housing, the transport mechanism includes a conveyor belt passing through the drying mechanism, a yarn hanging rod is arranged on the conveyor belt, and the housing is provided with a yarn inlet and a yarn outlet according to the running direction of the conveyor belt.

[0003] When in use, steam is passed into the heating tube to heat the internal space of the casing. The operator at the yarn inlet hangs the wet skein on the yarn hanging rod and starts the conveyor belt to dry the skein through the internal space of the casing. After drying, the operator at the yarn outlet removes the skein from the yarn hanging rod. Due to site limitations, traditional skein dryers can only dry a small amount of skein at a time, and often need to be dried in boxes multiple times, which wastes manpower and makes it difficult to control the drying quality of different batches or even the same batch. In order to improve the drying effect, the existing skein dryers need to increase the heating temperature to increase the amount of steam, which consumes more energy and creates a hot production environment, which is not operator-friendly.

[0004] Most of the existing hank dryers adopt a closed box design, in which a heating source is arranged, and the heating source is used to increase the temperature of the air in the box, thereby converting the moisture in the hank into a gaseous form to achieve the purpose of drying. However, the closed box is not conducive to the discharge of water vapor, and the air circulation in the dryer is poor. The continuous drying of the hank will cause the moisture in the hank to evaporate, which will gradually increase the humidity of the air in the box. When the temperature in the box is lowered or the hank is taken out, the moisture is easy to condense into water and re-wet the hank, thereby deteriorating the drying effect and reducing the efficiency of drying the hank.
