[0035] like Figures 1-6 As shown, it illustrates a clean plastic sheet dehydrator according to an embodiment of the present disclosure, comprising:
[0036] The frame 1 and the outer shell 2 are fixed to one side of the frame 1;
[0037] The feeding hood 3 and the separation component 5 are provided. The feeding hood 3 is located on the top of the outer shell 2, and the separation component 5 is located in the feeding hood 3 and the frame 1.
[0038] The drive motor 4 and the air drying component 6 are installed inside the frame 1.
[0039] The separation component 5 includes a conveying auger 5-1, which is located inside the outer shell 2. An inner cavity 5-2 is formed on the surface of the outer shell 2. An air inlet elongated hole 5-3 is formed on the inner surface of the inner cavity 5-2. A first centrifugal fan 5-4 is set on the top of the frame 1. The output end of the first centrifugal fan 5-4 is connected to the inner cavity 5-2. A separation hole 5-5 is formed on the bottom of the outer shell 2. A collection box 5-6 is set on the side surface of the frame 1. The collection box 5-6 is located directly below the separation hole 5-5. A drainage pipe 5-7 is set on the bottom of the collection box 5-6. A discharge port 5-8 is formed on the side surface of the outer shell 2.
[0040] In some examples, a separation component 5 is designed to achieve the effect of initial moisture separation. A conveying auger 5-1 is set inside the outer shell 2 to push the plastic. The top of the outer shell 2 has an inner cavity 5-2 and an air inlet 5-3. The top of the frame 1 is equipped with a first centrifugal fan 5-4, which can send air into the inner cavity 5-2. The air inlet 5-3 can blow air into the outer shell 2. The bottom of the outer shell 2 has a separation hole 5-5 for separating moisture outward. The side surface of the frame 1 is equipped with a collection box 5-6 and a drain pipe 5-7. The collection box 5-6 can collect the blown water and discharge it outward through the drain pipe 5-7. The side of the outer shell 2 has a discharge port 5-8, which can put plastic into the frame 1.
[0041] like Figures 1-6 As shown, this embodiment proposes a drying assembly 6 including a rotating cylinder 6-1, which is located at the output end of the drive motor 4. One end of the rotating cylinder 6-1 is rotatably connected to the side surface of the frame 1. The surface of the rotating cylinder 6-1 is provided with several turning plates 6-2, and the surface of the rotating cylinder 6-1 is provided with several air jets 6-3, which are located at intervals between the turning plates 6-2. A second centrifugal fan 6-4 is provided on the side surface of the frame 1, and a connecting pipe 6-5 is provided at the output end of the second centrifugal fan 6-4. The connecting pipe 6-5 is rotatably fitted inside the rotating cylinder 6-1, and multiple heating tubes 6-6 are installed inside the connecting pipe 6-5, with one end of each heating tube 6-6 located inside the rotating cylinder 6-1.
[0042] In some examples, to further dry the plastic, a drying assembly 6 is designed. A rotating cylinder 6-1 is installed at the output end of the drive motor 4, and multiple flipping plates 6-2 are installed on its surface. When the rotating cylinder 6-1 rotates, it can receive the falling plastic through the flipping plates 6-2 and flip the plastic outward. A second centrifugal fan 6-4 and a connecting pipe 6-5 are installed on one side of the frame 1. The connecting pipe 6-5 is rotatably fitted in the rotating cylinder 6-1 and will not rotate with the rotating cylinder 6-1. Multiple heating tubes 6-6 are installed in the connecting pipe 6-5 and located in the rotating cylinder 6-1 to heat the blown air. An air jet vent 6-3 is opened on the surface of the rotating cylinder 6-1 to spray the heated gas into the plastic to achieve the drying effect.
[0043] For example, such as Figure 4 As shown, the inner surface of the frame 1 has an arc-shaped transition structure, and the end face of the flipping plate 6-2 slides and fits against the inner surface of the frame 1.
[0044] In some examples, the curved structure, combined with the rotation path of the flipping plate 6-2, ensures that all the falling plastic enters the flipping plate 6-2.
[0045] For example, such as Figure 3 As shown, the cross-section of collection box 5-6 has a V-shaped structure.
[0046] In some examples, the V-shaped structure helps to concentrate water, making it easier to drain.
[0047] For example, such as Figure 4 As shown, a pair of baffles 7 are installed inside the feeding hood 3, and the baffles 7 are fixed at an inclined angle.
[0048] In some examples, by setting an inclined baffle 7, some of the gas can be blocked from being blown out of the feeding hood 3.
[0049] When dehydration is required, the plastic is put into the feeding hood 3, and then the conveying auger 5-1 is started to push the plastic in the outer shell 2. At the same time, the first centrifugal fan 5-4 is started to blow air into the inner cavity 5-2. The air is blown into the outer shell 2 through the air inlet 5-3. The air blows off the water on the plastic. The blown-off water flows into the collection box 5-6 through the separation hole 5-5, and then is discharged out through the drain pipe 5-7. The separated plastic falls into the frame 1. The drive motor 4 is started to control the rotating drum 6-1 to rotate. The plastic is flipped up by the tipping plate 6-2. The second centrifugal fan 6-4 and the heating tube 6-6 are started. The heated air is blown out through the jet nozzle 6-3 to dry the plastic. Finally, the plastic slides out through the tilt angle of the tipping plate 6-2.
[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
