Description

Technical Field

[0001] The utility model belongs to the field of fiber production equipment, and in particular relates to a novel full-volume drying roller for fiber raw yarn production. Background Art

[0002] When producing fiber raw yarn, the yarn ejected by the spinneret needs to be washed in a water washing tank after being drawn, and then dried using a drying roller. Figure 1 As shown, the return pipe 1 of the existing drying roller is arranged in the steam pipe 8, and the steam is passed through the interlayer between the steam pipe 8 and the return pipe 1, and input into the spool 2 in the roller body of the drying roller. The steam outlets on both sides of the spool 2 are connected to the braided tube 4 through the direct connector 3, and the steam is transported to the roller body 5 of the drying roller through the braided tube 4. The return port at the end of the spool 2 is connected to the collecting tank 7 through the reducing short wire 6 and the braided tube, and the condensed water after the steam condenses is discharged into the return pipe 1 through the collecting tank 7 and the braided tube. Since this structure needs to fix the braided tube and the condensed water recovery unit inside, it can only be designed as a semi-volumetric type, that is, the conical area near the outside of the roller body of the drying roller cannot be passed through, which results in that the amount of steam near the outside of the roller body of the drying roller is significantly less than the amount of steam near the inside of the roller body of the drying roller, and the steam is unevenly distributed, the cellulose on the drying roller is unevenly heated, and the condensed water is not smoothly collected due to the uneven heating.
