[0039] Please see Figure 1-6 In this embodiment of the invention, a plastic granule dehydration device includes a conveying box 1. The top of the conveying box 1 is fixed with a discharge port 2 that communicates with the interior of the conveying box 1. The discharge port 2 is used to provide feeding guidance for the material. One end of the conveying box 1 is fixed with a drive motor 3, which is used to provide power for conveying the material. The other end of the conveying box 1 is connected to a drying box 4. A drying mechanism 5 and a discharge mechanism 6 are distributed on the conveying box 1 and the drying box 4. The drying mechanism 5 is used to dry the material, and the discharge mechanism 6 is used to provide power for conveying and discharging the material.

[0040] The discharge mechanism 6 consists of a discharge unit and a vibration unit;

[0041] The discharge unit is used to scoop up some of the material in the drying chamber 4 and separate it from most of the material in the drying chamber 4, thereby improving drying efficiency.

[0042] The vibration unit is used to provide vibration force to the retrieved material, causing some of the material to flip and increasing the contact area with hot air.

[0043] The drying mechanism 5 includes a hot air pipe 501, an air outlet 502, and a material outlet 503;

[0044] Hot air duct 501 is fixed to the outer wall of drying oven 4. Hot air duct 501 is connected to an external hot air blower and is used to provide input guidance for external hot air.

[0045] The air outlet 502 is located on the top outer wall of the drying oven 4. The air outlet 502 is used to provide an outlet for the incoming hot air, thereby removing water vapor.

[0046] The discharge port 503 is fixed to one end of the outer wall of the drying box 4 and is connected to the drying box 4. The discharge port 503 is used to guide the discharge of the dried material.

[0047] The discharge unit includes a screw feed rod 601, a rotating rod 602, a connecting rod 603, and a scooping plate 604;

[0048] The screw feed rod 601 is rotatably installed inside the conveyor box 1, and one end of the screw feed rod 601 is connected to the output end of the drive motor 3 through a rotating shaft and a coupling. The screw feed rod 601 is used to provide thrust for the movement of materials.

[0049] The rotating rod 602 is axially sleeved on one end of the screw feed rod 601. The rotating rod 602 in the rotating state is used to drive the connecting rod 603 to rotate.

[0050] Multiple connecting rods 603 are circumferentially fixed to the outer wall of the rotating rod 602. The connecting rods 603 in the rotating state are used to drive the retrieval plate 604 to rotate.

[0051] The lifting plate 604 is fixed to one end of the connecting rod 603. The rotating lifting plate 604 is used to lift the material upward.

[0052] The vibration unit includes a first positioning block 605, a rotating block 606, a first positioning groove 607, a second positioning block 608, and a second positioning groove 609;

[0053] The first positioning block 605 is fixed to the outer wall of the rotating rod 602, and the first positioning block 605 is used to provide guidance for the movement of the rotating rod 602.

[0054] The rotating block 606 is rotatably installed inside the drying oven 4, and the rotating block 606 is used to provide support for the rotation of the rotating rod 602;

[0055] The first positioning groove 607 is formed on the inner side of the rotating block 606, and the first positioning groove 607 is used to provide guidance for the movement of the first positioning block 605.

[0056] The second positioning block 608 is fixed on the outer wall of the rotating rod 602. The first positioning block 605 and the second positioning block 608 are located at the two ends of the rotating rod 602 respectively. The second positioning block 608 cooperates with the second positioning groove 609 to drive the rotating rod 602 to rotate.

[0057] The second positioning groove 609 is formed at the end of the spiral feed rod 601, and the inner sides of the second positioning groove 609 and the first positioning groove 607 are the same.

[0058] When using this plastic granule dewatering device, the material to be dried is manually poured into the inside of the feed inlet 2 at once. The material enters the inside of the conveying box 1 through the feed inlet 2. By starting the drive motor 3, the drive motor 3 drives the spiral feed rod 601 to rotate. The rotating spiral feed rod 601 pushes the material inside the conveying box 1 to move. The residual water will flow out through the filter screen at the bottom of the conveying box 1, thus achieving one dewatering of the material until the material gradually enters the drying box 4. At the same time, the hot air fan connected to the hot air pipe 501 is started to blow hot air into the drying box 4 and the inside of the conveying box 1 through the hot air pipe 501 to dry the material.

[0059] During the rotation of the screw feeder 601, the rotating rod 602, which is axially sleeved at one end of the screw feeder 601, will also rotate with the rotation of the screw feeder 601. The rotation of the rotating rod 602 will drive the connecting rod 603 fixed on its outer wall to rotate, thereby driving the scooping plate 604 at the end of the connecting rod 603 to rotate circumferentially around the rotating rod 602. During the rotation, the scooping plate 604 will scoop up the material that has entered the drying chamber 4, so that the material moves circumferentially with the rotation of the scooping plate 604, so that some of the material is separated from other materials, which is convenient for hot air to dry the material.

[0060] During the rotation of the rotating rod 602, the first positioning block 605 on the outer wall of the rotating rod 602 will rotate along with the rotating rod 602. When the first positioning block 605 rotates to the predetermined position, the friction between the first positioning block 605 and the movable groove of the first positioning groove 607 cannot overcome the gravity. The first positioning block 605 will drive the rotating rod 602 to move along the inner side of the movable groove of the first positioning groove 607, so that the rotating rod 602 contacts the bottom of the inner side of the rotating block 606 again from above, generating an impact force. The impact force is transmitted to the inner side of the scooping plate 604. Some of the material jumps up and flips under the vibration, increasing the contact area with the hot air. Some of the dried and dehydrated material slides down the inner inclined surface of the scooping plate 604 at the highest position of the scooping plate 604 to the inner side of the discharge port 503, completing the automatic discharge operation of the dried material.

[0061] exist Figure 1-6In the first positioning groove 607, a circular central groove and a vertical movable groove are combined. The vertical movable groove is distributed around the periphery of the circular central groove. The second positioning block 608 has the same size as the first positioning groove 607. The inner diameter of the first positioning groove 607 is larger than the outer diameter of the rotating rod 602. When the lowest point of the rotating rod 602 is at the lowest point of the inner diameter of the first positioning groove 607, the end of the first positioning block 605 away from 602 is in the movable groove of the first positioning groove 607. Multiple scooping plates 604 and connecting rods 603 are provided. Multiple scooping plates 604 and connecting rods 603 are distributed in a ring around the rotating rod 602 on the outer wall of the rotating rod 602. There is a height difference between the two ends of the inner side of the scooping plate 604. The tilt angle is such that the side closer to the conveyor box 1 is the higher end, which is used to better convey the dried material.

[0062] When this plastic granule dewatering device is in use, the rotating rod 602 vibrates as it returns to its original position under the rotation of the first positioning block 605 and the rotating block 606. The different positions of the scooping plate 604 produce different effects. To guide the material inside the scooping plate 604 at the highest point, the material will jump up and turn over under vibration, increasing the contact area with hot air. The material moved to the scooping plate 604 at the highest position will enter the inside of the discharge port 503 and slide down along the discharge port 503 to the outside, collecting the dried material. It should be noted that the rotation speed of the rotating rod 602 is the same as the rotation speed of the screw feed rod 601, but the screw feed rod 601 needs to rotate more slowly so that the material inside the drying box 4 has more time to contact the hot air.

[0063] exist Figure 1-6 In the middle: the bottom of the conveying box 1 is formed with a filter screen for filtering water, and a collection tank for collecting filtered water is formed below the filter screen.

[0064] When this plastic granule dewatering device is in use, the material is pushed by the screw feeder 601, and the water in the material will flow out through the filter screen formed at the bottom of the conveying box 1. There is no need for manual water filtration, which reduces the working steps and further improves the working efficiency.

[0065] The working principle of this invention is as follows: The material to be dried is manually poured into the inlet 2 at once, entering the inner side of the conveying box 1 through the inlet 2. By starting the drive motor 3, the drive motor 3 drives the spiral feed rod 601 to rotate. The rotating spiral feed rod 601 pushes the material inside the conveying box 1 to move. Residual water will flow out through the filter screen at the bottom of the conveying box 1, achieving a first dehydration of the material until the material gradually enters the drying box 4. At the same time, the hot air pipe 501 is connected to the outside. The hot air blower blows hot air into the drying chamber 4 and the conveying chamber 1 through the hot air pipe 501 to dry the materials. During the rotation of the screw feeder 601, the rotating rod 602, axially sleeved at one end of the screw feeder 601, also rotates. The rotation of the rotating rod 602 drives the connecting rod 603 fixed to its outer wall to rotate, thereby causing the scooping plate 604 at the end of the connecting rod 603 to rotate circumferentially around the rotating rod 602. During the rotation of the scooping plate 604… The material entering the drying chamber 4 is scooped up, causing it to move circumferentially as the scooping plate 604 rotates, separating some material from others to facilitate drying with hot air. During the rotation of the rotating rod 602, the first positioning block 605 on the outer wall of the rotating rod 602 rotates accordingly. When the first positioning block 605 rotates to a predetermined position, and the friction between the first positioning block 605 and the movable groove of the first positioning groove 607 cannot overcome gravity, the first positioning block 605 will... The rotating rod 602 moves along the inner side of the movable groove of the first positioning groove 607, causing the rotating rod 602 to contact the bottom of the inner side of the rotating block 606 again from above, generating an impact force. The impact force is transmitted to the inner side of the scooping plate 604, and some of the material jumps up and flips over under the vibration, increasing the contact area with the hot air. Meanwhile, some of the dried and dehydrated material slides down the inclined inner side of the scooping plate 604 at the highest position of the scooping plate 604 to the inner side of the discharge port 503, completing the automatic discharge operation of the dried material.

[0066] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
