Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 to 5 shown, the PET plastic scrap dehydration device in this embodiment includes a dehydrator 1. A feeding port 2 is installed at the front end of the dehydrator 1. Through the feeding port 2, materials can be put into the interior of the dehydrator 1. Multiple sets of vertical conveying pipelines 4 are installed inside the dehydrator 1. The multiple conveying pipelines 4 are on the same horizontal line. The upper ends of the conveying pipelines 4 penetrate through the dehydrator 1 and extend upward. Part of the length of the conveying pipelines 4 is located above the dehydrator 1 and not inside the dehydrator 1. A plurality of through slots 7 are arrayed and opened on the surface of the conveying pipelines 4 located inside the dehydrator 1. Through the through slots 7, the conveying pipelines 4 and the dehydrator 1 can be connected and communicated together. The materials inside the dehydrator 1 will enter the interior of the conveying pipelines 4 through the through slots 7. A conveying box 6 is installed at the upper end of the dehydrator 1 at a position outside the multiple conveying pipelines 4. A first spiral auger 3 is rotatably connected inside the conveying pipeline 4. The materials entering the interior of the conveying pipeline 4 will be conveyed upward by the first spiral auger 3. The lower end of the first spiral auger 3 is connected with a driving device. The driving device is a common servo motor on the market and can drive the first spiral auger 3 to rotate. The upper end of the first spiral auger 3 and the upper end of the conveying box 6 are on the same horizontal line. A discharging structure 5 is installed at both the front and rear ends of the conveying box 6. The materials conveyed to the uppermost end of the conveying pipeline 4 will enter the interior of the conveying box 6 and be discharged through the discharging structure 5.

[0022] Specifically, the upper surface of the conveying box 6 and the upper ends of the conveying pipelines 4 are on the same horizontal line. Slopes 12 are provided at both the front and rear ends of the conveying box 6. Through holes 11 are opened at positions adjacent to the lower ends of the slopes 12 on the inner wall of the conveying box 6. The materials entering the interior of the conveying box 6 will slide down through the slopes 12 on both sides and pass through the through holes 11.

[0023] Further, the conveying pipeline 4 includes a dehydration pipeline 401 and a feeding pipeline 402. The position of the conveying pipeline 4 inside the dehydrator 1 is the feeding pipeline 402. Through grooves 7 are formed on the surface of the feeding pipeline 402. The dehydration pipeline 401 is arranged at the position above the dehydrator 1 at the upper end of the feeding pipeline 402. The materials inside the feeding pipeline 402 will be mixed with clear water and cannot be dehydrated. During the continuous upward conveying process, the materials will enter the inside of the dehydration pipeline 401, and the clear water cannot enter the inside of the dehydration pipeline 401. The water adhering to the surface of the materials will also slide off under the action of gravity, achieving the dehydration effect.

[0024] Further, a water outlet pipeline 8 is installed on the lower side of one end surface of the dehydrator 1. A filter membrane is arranged inside the water outlet pipeline 8 and is detachably arranged. By controlling the opening of the water outlet pipeline 8, the water inside the dehydrator 1 can be discharged. Through multiple filter membranes, relatively fine crushed materials can be retained inside the dehydrator 1. After repeated use for many times, some relatively fine fragments will remain inside the dehydrator 1 and cannot be discharged. At this time, manual cleaning is required.

[0025] Further, a cover 9 is installed at the upper end of the dehydrator 1. A fan group 10 is installed at the upper end of the cover 9. The fan group 10 and the multiple conveying pipelines 4 are in the same vertical plane. By continuously drying the multiple conveying pipelines 4 through the fan group 10, the air flow inside the conveying pipelines 4 can be accelerated, and the water on the surface of the materials inside the conveying pipelines 4 can be accelerated to fall off.

[0026] Furthermore, the discharging structure 5 includes a discharging box 501. A feeding hole 503 matching the through hole 11 is formed at one end of the discharging box 501. A discharging port 504 is formed at the lower end of the discharging box 501. A second spiral auger 502 is rotatably connected inside the discharging box 501. One end of the second spiral auger 502 is connected with a driving device. The materials inside the conveying box 6 will enter the inside of the discharging box 501 through the through hole 11 and the feeding hole 503 and are horizontally conveyed by the second spiral auger 502, and finally discharged through the discharging port 504 with the opening facing downwards.

[0027] The usage method of this embodiment is as follows: The materials and clear water are put into the inside of the dehydrator 1 through the feeding port 2. The plastic crushed materials inside will enter the inside of the conveying pipeline 4 through the through grooves 7 during the water flow process. The driving motor will drive the first spiral auger 3 to rotate. During the rotation of the first spiral auger 3, the materials entering the inside of the conveying pipeline 4 will be conveyed upwards. When the materials are conveyed to the uppermost end, they will enter the inside of the conveying box 6, enter the two discharging structures 5 through the conveying box 6, and be output through the discharging structures 5.
