Description

Technical Field

[0001] The utility model relates to the field of textile manufacturing, in particular to a steam circulation device for a cashmere drying machine. Background Art

[0002] Textile manufacturing refers to the production activities of cotton, chemical fiber, wool, linen and silk textile products. Cashmere textiles need to be dried during the manufacturing process. Generally, the raw cashmere is dried by electric heating inside the dryer. Steam is generated during the drying process of cashmere. The drying process is completed after the steam is discharged. However, this drying method cannot completely convert the water in the raw material into steam, and some condensed water remains in the dryer, which leads to incomplete drying and low drying efficiency. In view of the above situation, external heated air is transported to the dryer. During the drying process of the raw material, the moisture in the raw material is taken out to form steam and output to the outside, thereby completing the drying. Since the heated air continuously enters and the steam formed is continuously discharged, the residual moisture can be greatly reduced and the drying effect is good. However, in this method, the steam discharged from the dryer is usually discharged directly into the air, and after air cooling, it becomes water droplets and falls down, which greatly wastes the heat in the steam and causes a waste of resources. Summary of the invention
