Embodiment 1
[0052] see Figure 1-10 , a drying method suitable for high-shrinkage polyester chips, S1. transporting high-shrinkage polyester chips from a hopper to a conveying device in advance;
[0053] S2. The conveying device puts the high-shrinkage polyester chips into the fluidized bed for pre-crystallization treatment;
[0054] S3. At this time, the hot air blowing device 2 blows hot air into the fluidized bed, and makes the wind-moving isolation shaking ball 5 float in the fluidized bed, and acts on the high-shrinkage polyester chips together with the hot air;
[0055] S4. Intermittently increase the pressure of the hot air blowing device 2 into the fluidized bed, so that the shaker telescopic one-way tube 10 drives the same polarity vibrating bubble ball 11 to act on the telescopic protective foam 8, so that the telescopic protective foam 8 produces intermittent Shaking, bouncing high-shrinkage polyester chips;
[0056] S5. After the pre-crystallization treatment is completed, t...
Embodiment 2
[0061] see Figure 1-10 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 2 and embodiment 1 is: please refer to Figure 2-5 , the fluidized bed includes a fluidized bed body 1, the lower end of the fluidized bed body 1 is fixedly installed with a hot air blowing device 2 connected with it, the fluidized bed body 1 is fixedly connected with a sliced boiling net plate 3, and the sliced boiling net plate 3 is fixed inside A plurality of isolated ventilating boxes 4 are connected, and a plurality of blasting flexible telescopic tubes 6 connected with the hot air blowing device 2 are fixedly connected in the isolated ventilating box 4, and the upper end of the blasting flexible telescopic tubes 6 extends to the outside of the isolated ventilating box 4 , see ima...
Embodiment 3
[0065] see Figure 1-10 , wherein the same or corresponding components as those in Embodiment 2 use the corresponding reference numerals as in Embodiment 2, and for the sake of simplicity, only the differences from Embodiment 2 are described below. The difference between this embodiment 3 and embodiment 2 is: please refer to Figure 9 The outer end of the telescopic protective bubble 8 is fixedly connected with a plurality of homopolar magnetic bubbles 9, the homopolar magnetic bubbles 9 are filled with a plurality of homopolar vibrating particles 901, and the homopolar vibrating bubble ball 11 is filled with homopolar vibrating particles 901. Coordinated homopolar tension magnetic material 1101. Due to the mutual cooperation of homopolar tension magnetic materials 1101 and homopolar vibrating particles 901, due to the principle of homopolar repulsion, when the homopolar vibration ball 11 is close to the homopolar magnetic bubble 9, the volume of the homopolar magnetic bubble...
