[0027] according to Figure 1-Figure 3 and Figure 8 As shown, the hot air blower 5 is electrically connected to the controller 4, the air outlet end of the connecting pipe 6 is fixedly passed through the lower side of the tank body 1, the electric valve 7 is electrically connected to the controller 4, the annular block 13 is located between two rubber rings 14, and the motor 8 is electrically connected to the controller 4, which can drive the round rod 201 to rotate with the cooperation of the controller 4 and the motor 8.

[0028] according to Figure 1-Figure 5 and Figure 8 As shown, the porous shell 10 is located inside the tank body 1, the top of the porous shell 10 is in contact with the bottom of the tank cover 9, the inner walls of the two rubber rings 14 are in contact with the outer wall of the porous shell 10, the water inlet end of the guide hole 15 is located above one of the rubber rings 14, and the water outlet end of the guide hole 15 is located below the other rubber ring 14, so that the water above one of the rubber rings 14 can be conveniently diverted away under the action of the guide hole 15.

[0029] according to Figure 1-Figure 9 As shown, the two stirring plates 11 are both inside the porous shell 10, the output end of the motor 8 is installed with the bottom end of the round rod 201, the bottom end of the round rod 201 is movable through the bottom of the inner wall of the porous shell 10, and the one-way valve 12 is between the tank body 1 and the porous shell 10. Under the action of the one-way valve 12, the water inside the tank body 1 can be prevented from flowing into the inside of the connecting pipe 6.

[0030] according to Figure 1-Figure 9 As shown, the bottom end of the round rod 201 movably passes through the bottom of the inner wall of the tank body 1, the bottom end of the first round tube 203 movably embeds in the bottom of the inner wall of the porous shell 10, and two card slots 205 are both opened at the bottom of the inner wall of the porous shell 10, so that the porous shell 10 can be driven to rotate inside the tank body 1 with the cooperation of the two card slots 205, the two card blocks 206, the rotating first round tube 203, the second bearing and the annular block 13.

[0031] The effect achieved by the whole mechanism is as follows: when the PET bottle flakes need to be dried, the controller 4 is first connected to the external power supply, and then the tank cover 9 is removed, and then a proper amount of PET bottle flakes are placed inside the porous shell 10, and then the tank cover 9 is reset to its original position, and then the prepared collection bucket is placed directly below the electric valve 7, and then the valve of the electric valve 7 is opened by the controller 4, and finally the motor 8 is started by the controller 4. At this time, the started motor 8 will drive the round rod 201 to rotate, and the rotating round rod 201 will drive the first round tube 203 to rotate under the cooperation of the T-shaped hole 207, the cylindrical hole 208 and the fixing bolt 209, and at the same time, the rotating first round tube 203 will drive the two blocks 206 to rotate, and the two rotating The movable block 206 will drive the porous shell 10 to rotate inside the tank body 1 under the cooperation of the two slots 205, the second bearing and the annular block 13. At this time, the rotating porous shell 10 can dehydrate the PET bottle flakes inside it. When the rotating porous shell 10 dehydrates the PET bottle flakes inside it, the water thrown out by the rotating porous shell 10 will flow along the inner wall of the tank body 1 to the bottom of the inner wall of the tank body 1 under the action of its own gravity. At this time, part of the thrown out water will flow directly to the bottom of the inner wall of the tank body 1, and the other part of the water will accumulate above one of the rubber rings 14, and then flow to the bottom of the inner wall of the tank body 1 with the cooperation of the guide hole 15, and then flow to the bottom of the inner wall of the tank body 1. The water will flow into the collection bucket with the cooperation of the electric valve 7 that opens the valve. At the same time, under the action of the one-way valve 12, the water flowing to the bottom of the inner wall of the tank body 1 will not flow into the connecting pipe 6. When the PET bottle pieces inside the porous shell 10 complete the dehydration operation and the water inside the tank body 1 flows into the collection bucket, the electric valve 7 is first closed by the controller 4, and then the motor 8 is turned off by the controller 4. At this time, the closed motor 8 will stop the porous shell 10 from rotating with the cooperation of the above-mentioned components. When the porous shell 10 stops rotating, the tank cover 9 is first removed, and then the second round tube 204 is manually rotated until the insides of the two sets of threaded holes 211 are connected, and then the fixing bolts are tightened with the cooperation of the prepared tools and the auxiliary holes 210. 209 is taken out, and then the hand-tightening bolt 202 is removed, and then a force is applied to the second round tube 204 to make it move vertically upward. At this time, the second round tube 204 that moves vertically upward will drive the two stirring plates 11 to move together, and at the same time, the second round tube 204 that moves vertically upward will drive the first round tube 203 to move vertically upward with the cooperation of the first bearing, and the first round tube 203 that moves vertically upward will drive the two clamping blocks 206 to move together. When the top of the second round tube 204 and the top of the round rod 201 are on the same horizontal plane, the movement of the second round tube 204 is stopped first. At this time, the second round tube 204 that stops moving will stop the two clamping blocks 206 from moving with the cooperation of the above-mentioned components, and at the same time, the two clamping blocks 206 are separated from the corresponding clamping grooves 205.Then, the hand-tightening bolt 202 is reset to its original position, that is, the round rod 201, the first round tube 203 and the second round tube 204 can be fixed together by using the cooperation of the two groups of threaded holes 211 and the reset hand-tightening bolt 202 (the threaded end of the reset hand-tightening bolt 202 will be located between the two groups of threaded holes 211), and then the tank cover 9 is reset to its original position, and then the motor 8 and the hot air blower 5 are started by the controller 4. At this time, the started hot air blower 5 will transport the hot air to the inside of the connecting pipe 6, and then with the cooperation of the one-way valve 12, it will be transported to the inside of the tank body 1. At the same time, the hot air transported to the inside of the tank body 1 will dry the PET bottle flakes inside the porous shell 10 with the cooperation of the tank body 1, the tank cover 9 and the porous shell 10, and then the hot air will exchange heat with the water on the PET bottle flakes, and then the water on the PET bottle flakes will turn into water vapor and be removed from the air outlet of the tank cover 9. At the same time, the started motor 8 will bring The movable round rod 201 rotates, and the rotating round rod 201 will drive the two stirring plates 11 to rotate inside the porous shell 10 under the cooperation of the four threaded holes 211, the hand-tightening bolts 202, the second round tube 204 and the first round tube 203, so as to stir the PET bottle flakes inside the porous shell 10 and improve the drying efficiency of the PET bottle flakes inside the porous shell 10. When the PET bottle flakes inside the porous shell 10 are dried, the controller 4 is used to turn off the hot air blower 5 and the motor 8, and then the dried PET bottle flakes are removed from the porous shell 10. Then, the reverse operation is performed according to the above operation steps, so that the two blocks 206 and the fixing bolts 209 are reset to their original positions (if the two blocks 206 are aligned with the two slots 205, the porous shell 10 can be manually rotated), and then the above operation steps can be performed to dry the remaining PET bottle flakes.

[0032] Among them, the first bearing and the second bearing are both common parts in real life.

[0033] Among them, the controller 4 (PLC controller), the hot air blower 5, the motor 8, the one-way valve 12 and the electric valve 7 are all existing technologies, and their working principles are all public technologies. Their models can be selected according to actual conditions and no excessive explanation is given here.
