[0002] Polyester fiber, which we commonly call "polyester", is a synthetic fiber made of organic dibasic acids and diols through chemical condensation. It is a kind of high molecular compound and is now the most important type of synthetic fiber. Polyester fiber has many advantages. First, it has excellent wrinkle resistance and shape retention. The clothes made from it are not easy to wrinkle during wearing and can maintain the original shape of the clothes. Secondly, polyester fiber has high strength and elastic recovery ability, which makes the woven fabric strong and durable, and can quickly restore to its original shape. In addition, polyester fiber also has the characteristics of wear resistance and non-stickiness, making the fabric look neater.

At the same time, the dryer has high power consumption and high cost, which needs to be improved. Therefore, the technicians in this field provide a dryer for producing high-strength and high-modulus polyethylene fibers to solve the problems raised in the above background technology.

[0027] Specifically, a heat dissipation cylinder 12 is provided inside the dryer 1, and a plurality of heat dissipation holes 14 are inlaid on the surface of the heat dissipation cylinder 12. The heat dissipation holes 14 evenly dissipate the heat inside the heat dissipation cylinder 12, and a rotating rod 13 is connected to the outside of the heat dissipation cylinder 12. The rotating rod 13 rotates through the heat dissipation cylinder 12 to stir the fibers inside the dryer 1, so that the fibers are located inside the dryer 1, avoiding the fibers from piling up, and quickly dissipating the moisture inside the fibers, thereby accelerating the drying speed of the fibers.

[0028] An equipment box 2 is installed on the side of the dryer 1, and a moisture collector 3 is installed on the top of the dryer 1. The moisture collector 3 includes: a device tube 31, which is connected to the bottom of the moisture collector 3, and a mounting screw 32 is installed below the device tube 31; a separator 33, which is arranged below the mounting screw 32; the separator 33 is arranged above the inside of the dryer 1, and the moisture collector 3 is obliquely installed above the dryer 1 through the device tube 31, and the moisture collector 3 can collect moisture inside the dryer 1.

[0029] Specifically, the moisture collector 3 is disposed above the dryer 1 through the collector pipe 31 and the mounting screws 32 , and the moisture collector 3 can collect and discharge the moisture inside the dryer 1 .
