Description

Technical Field

[0001] The invention relates to a drying device for fabric dyeing and finishing, belonging to the technical field of printing and dyeing equipment. Background Art

[0002] Many processes in the printing and dyeing production process require drum dryers to achieve flat-width drying. Currently, all drum dryers are vertical, consisting of columns, drying drums, transmission mechanisms, steam inlet and drainage systems, etc. They are often used in conjunction with some related unit machines. When in use, the drying drum uses water vapor as the heat source, and the flat-width wet fabric is tightly attached to each actively rotating hot drum surface with a certain wrap angle. During the operation, the heat energy conducted by the drum surface is absorbed to vaporize the moisture to achieve the drying of the fabric. After the water vapor in the drum is cooled by heat conduction, condensed water will be formed. The condensed water will form a water film on the inner surface of the drying drum as the drying drum rotates at high speed, affecting the heat conduction. For this reason, a turbulator is installed in the drying drum. The turbulator includes It includes multiple external connecting rings and multiple spoiler rods. The multiple connecting rings need to be coaxially arranged in the drying cylinder. Multiple spoiler rods in contact with the inner wall of the drying cylinder are radially evenly distributed and fixed on the outer edges of the multiple connecting rings. In order to make the turbulators smoothly stick to the inner wall of the drying cylinder, the connecting rings adopt a retractable and expandable structure. After the turbulators with the contracted connecting rings are put into the drying cylinder, the workers enter the drying cylinder to expand each connecting ring to achieve the fitting installation on the inner wall of the drying cylinder. Due to the limited space in the drying cylinder, it is very troublesome for the workers to enter the drying cylinder to operate. During the operation, each connecting ring is expanded front and back, which may cause uneven expansion of each connecting ring due to uneven force front and back, resulting in improper installation. Summary of the invention
