[0002] Small granular substances made from various raw materials (such as waste rubber, plastic resin, etc.) through specific processes are called plastic granules. Plastic granules can be transformed into various industrial and household products through various plastic processes, making them suitable for manufacturing a variety of industrial and household products. During the production process, plastic granules are usually placed in water for cooling. After cooling, the surface of the plastic granules is covered with a large amount of water, which needs to be removed using evaporation equipment.

[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0034] The present invention provides the following preferred embodiments:

[0035] Example 1, as Figures 1-10 As shown, a plastic pellet moisture evaporation device includes two support frames 1, as well as a feeding mechanism, a spreading mechanism and a drying mechanism;

[0036] The slab spreading mechanism includes a heat-conducting box 3, a drive assembly, and two sliding assemblies. The two sliding assemblies are both arranged between two support frames 1. The heat-conducting box 3 is arranged above the two sliding assemblies. The heat-conducting box 3 is made of heat-conducting material. The drive assembly is arranged on one side of the heat-conducting box 3.

[0037] The drying mechanism includes a drying chamber 4, an air inlet assembly, and a transfer assembly. The drying chamber 4 is located above the heat conduction box 3, the air inlet assembly is located above the drying chamber 4, and the transfer assembly is located between the drying chamber 4 and the heat conduction box 3.

[0038] The feeding mechanism includes a feed inlet 2 and a rotating assembly. The rotating assembly is installed above the drying chamber 4, and the feed inlet 2 is installed on top of the rotating assembly.

[0039] like Figures 1-10As shown, the rotating assembly includes a feed cylinder 5, a first motor 6, a rotating shaft 7, and multiple fan blades 8. The feed cylinder 5 is fixedly installed on the top of the drying chamber 4, the first motor 6 is fixedly installed on one side of the feed cylinder 5, the rotating shaft 7 is rotatably installed inside the feed cylinder 5, and one end of the rotating shaft 7 passes through the feed cylinder 5 and is fixedly connected to the output end of the first motor 6. Multiple fan blades 8 are all installed on the outer wall of the rotating shaft 7.

[0040] When plastic granules need to be dried, the plastic granules are poured into the feed inlet 2. The plastic granules entering the feed inlet 2 first enter the rotating assembly. The first motor 6 drives the rotating shaft 7 and multiple fan blades 8 to rotate, feeding the plastic granules in segments. This prevents the plastic granules from accumulating above the heat conduction box 3 when they fall into the heat conduction box 3, thus preventing a large number of plastic granules from piling up together and sticking together, which would affect the drying effect.

[0041] like Figures 1-10 As shown, each sliding component includes a slide rod 9, two U-shaped frames 10 and multiple rotating wheels 11. The slide rod 9 is fixedly installed between two support frames 1. The two U-shaped frames 10 are fixedly installed below the heat conduction box 3. Each pair of rotating wheels 11 is located on one side of the slide rod 9. The two rotating wheels 11 located at the same end are rotatably installed in one U-shaped frame 10.

[0042] The heat-conducting box 3 is guided by the slide rod 9, causing it to move back and forth under the traction of the connecting rod 16 and the guidance of the slide rod 9. This shakes and flattens the plastic granules above the heat-conducting box 3, making the plastic granules evenly dispersed and effectively improving the drying effect of the drying mechanism on the plastic granules.

[0043] like Figures 1-10 As shown, the drive assembly includes a mounting plate 12, a second motor 13, a turntable 14, a rotating rod 15, a connecting rod 16, and a mounting bracket 17. The mounting bracket 17 is fixedly installed on one side of the heat conduction box 3. The mounting plate 12 is fixedly installed between two sliding rods 9. The second motor 13 is fixedly installed above the mounting plate 12. The turntable 14 is fixedly installed at the output end of the second motor 13. The rotating rod 15 is fixedly installed on the side of the turntable 14 away from the second motor 13. The two ends of the connecting rod 16 are rotatably connected to the rotating rod 15 and the mounting bracket 17, respectively.

[0044] The second motor 13 rotates, driving the turntable 14 and the rotating rod 15 to rotate. Since the two ends of the connecting rod 16 are rotatably connected to the rotating rod 15 and the mounting bracket 17 respectively, when the rotating rod 15 rotates on the turntable 14, it will drive the connecting rod 16 to move. The connecting rod 16 will drive the heat conduction box 3 to move through the mounting bracket 17. The heat conduction box 3 slides on the slide rod 9 through multiple rotating wheels 11 installed below. The slide rod 9 guides the heat conduction box 3, causing it to move back and forth under the traction of the connecting rod 16 and the guidance of the slide rod 9. This shakes and flattens the plastic granules above the heat conduction box 3, making the plastic granules evenly dispersed and facilitating the drying of the plastic granules.

[0045] like Figures 1-10 As shown, the air intake assembly includes an air pump 18, a heating box 19, an air supply pipe 20, three connecting pipes 21, and multiple nozzles 22. The air pump 18 is located above the drying box 4, the heating box 19 is located to one side of the air pump 18, and the air supply pipe 20 is located on the side of the heating box 19 away from the air pump 18. Each connecting pipe 21 passes through the drying box 4 and is connected to the air supply pipe 20. Multiple nozzles 22 are evenly installed on the three connecting pipes 21.

[0046] Specifically, the output end of the air pump 18 is connected to the input end of the heating box 19, and the output end of the heating box 19 is connected to one end of the air supply pipe 20;

[0047] When drying plastic granules, firstly, outside air is introduced into the input end of the heating box 19 by the air pump 18. The heating box 19 heats the air and then sends the heated air into the air supply pipe 20 through the output end. The hot air entering the air supply pipe 20 will enter the three connecting pipes 21. The three connecting pipes 21 will spray the hot air evenly through the nozzles 22 to dry the plastic granules above the heat conduction box 3. Specifically, the heating box 19 is equipped with heating wires for heating the gas entering the heating box 19.

[0048] like Figures 1-10 As shown, the transmission assembly includes two air outlets 23, a fixed frame 24, a third motor 25, a belt 28, two pulleys 26, two drive shafts 29, two sealing shells 30, two fans 31, and two connecting pipes 32. The two air outlets 23 are both located on one side of the drying chamber 4. Each sealing shell 30 is installed on one side of one air outlet 23. The fixed frame 24 is installed on one side of one sealing shell 30. The third motor 25 is fixedly installed on the side of the fixed frame 24 away from the sealing shell 30. Each drive shaft 29 is rotatably mounted on one sealing shell 30. The two pulleys 26 are respectively fixedly mounted on the two drive shafts 29. Each fan 31 is located inside one sealing shell 30 and is fixedly connected to one drive shaft 29. The output end of the third motor 25 is fixedly connected to one of the drive shafts 29. The belt 28 is sleeved between the two pulleys 26.

[0049] After drying, the hot air flows into the drying chamber 4. At this time, the controller controls the third motor 25 to rotate. The third motor 25 drives a drive shaft 29 to rotate. When the drive shaft 29 rotates, it drives a pulley 26 and a fan 31 to rotate. Through the belt 28, it drives another pulley 26 to rotate, which in turn drives another fan 31 to rotate. The two fans 31 generate suction when they rotate, which draws the hot air inside the drying chamber 4. The hot air is introduced into the sealed shell 30 through the air outlet 23 on the surface of the drying chamber 4 and guided through the two connecting pipes 32. As the hot air enters the heat-conducting box 3, due to its lower density, it rises as it enters the lower end of the box, spreading throughout a large area and heating the box evenly. This raises the temperature of the box, allowing it to heat and dry the plastic granules above it. The multiple nozzles 22 on the top of the drying box 4 further dry the granules. Finally, the air is exhausted through the exhaust port 35 on the higher side of the box. This design effectively utilizes the hot air, saving energy in the factory.

[0050] like Figures 1-10 As shown, the slide bar 9, the heat conduction box 3 and the drying box 4 are all inclined, and multiple exhaust holes 35 are opened on the higher side of the heat conduction box 3;

[0051] By tilting the box, the plastic granules above the heat-conducting box 3 can be discharged through the discharge port 33 opened at the lower end of the heat-conducting box 3.

[0052] like Figures 1-10 As shown, the top of the heat conduction box 3 is provided with a discharge port 33, and a limit plate 34 is installed above the discharge port 33;

[0053] By installing a V-shaped limiting plate 34 on the top of the heat conduction box 3, the plastic granules above the heat conduction box 3 are gathered, making it easier for the plastic granules to enter the discharge port 33 for discharge.
