[0002] As we all know, the core task of the winding process is to remove defects in the yarn, such as long defects, short defects, different-colored fibers, lint, etc. Every time the winding machine removes a defect, it will use the air twisting system to twist the yarn. If the compressed air contains substances such as oil and water, it will directly affect the quality of the yarn, thereby affecting the company's benefits.

[0003] After searching, it was found that the application number is CN202221707146.6, and the name is a compressed air dehydration and deoiling purification device for spinning. The application proposes a method of separation using a cyclone separator. However, the cyclone separator has a low removal efficiency for droplets with a particle size of less than 300 microns, and the working efficiency can be further improved. At the same time, the liquid collection box at the bottom of the cyclone separator needs to be cleaned and drained regularly, which is also more troublesome and can be further improved.

The plate 14 moves through the slot, and the compressed air enters the condenser 3 through the first air pipe 2.

The moisture and oil droplets are absorbed by the absorbent cotton 17, and the clean compressed air is discharged along the outlet pipe 10 to complete the dehydration and deoiling operation. The stepper motor 9 starts at regular intervals, driving the unsaturated absorbent cotton 17 to rotate between the second air pipe 4 and the outlet pipe 10 for uninterrupted dehydration and deoiling. The saturated absorbent cotton 17 rotates to the extrusion plate 14. On the other hand, the hydraulic rod 12 extends, pushing the squeezing plate 14 upward, and the squeezing plate 14 squeezes the absorbent cotton 17. The oil and water inside the absorbent cotton 17 are squeezed out, pass through the filter hole 18 into the bottom box 11, and are discharged along the drain pipe 13, completing automatic cleaning, eliminating the trouble of frequent manual cleaning and improving the convenience of use. At the same time, the absorbent cotton 17 can adjust the filtration and separation efficiency by customizing the gap size.

The moisture and oil droplets are absorbed by the absorbent cotton 17, and the clean compressed air is discharged along the outlet pipe 10, completing the dehydration and oil removal operation. The stepper motor 9 is started at intervals to drive the unsaturated absorbent cotton 17 to rotate between the second air supply pipe 4 and the outlet pipe 10 for uninterrupted dehydration and oil removal. The saturated absorbent cotton 17 rotates above the squeezing plate 14, and the hydraulic rod 12 extends to push the squeezing plate 14 upward. The squeezing plate 14 squeezes the absorbent cotton 17, and the oil and water inside the absorbent cotton 17 are squeezed out and pass through the filter holes 18 into the bottom box 11 and are discharged along the drain pipe 13, completing automatic cleaning, eliminating the trouble of frequent manual cleaning and improving the convenience of use.
