[0028] The cooling mechanism includes a collecting box 2 located between the installation box 1 and the drying box 3. A discharge pipe is connected to one side of the outer wall of the collecting box 2, and is connected to the external cooling pool through the discharge pipe through the heat exchanger to fully utilize the heat energy of the plastic particles.

[0029] The inner wall of the rotary drum 4 is fixedly connected with a spiral blade 13. When the delivery pipe 7 is connected to an external water source, a nozzle 12 on the delivery pipe 7 sprays and cools the plastic particles in the rotary drum 4. When the rotary drum 4 rotates between the installation box 1 and the drying box 3, the plastic particles in the rotary drum 4 are fully cooled.

[0030] A fixed plate 20 is fixedly connected to the lower surface of the connecting plate 6, and a fan-shaped tooth plate 17 is movably connected to the surface of the fixed plate 20. An arc tube 18 that penetrates the delivery pipe 7 is fixedly installed on the surface of the fan-shaped tooth plate 17. A plurality of spaced nozzles 19 are penetrated and connected on the outer contour of the arc tube 18. Evenly distributed filtering holes are opened on the outer contour of the rotary drum 4 located on the inner side of the vertical plate 5. An output pump 10 is fixedly installed on the connecting plate 6. The output end of the output pump 10 is connected to the delivery pipe 7, and the input end of the output pump 10 is connected to the external cooling pool.

[0031] The output pump 10 located on the connecting plate 6 is started, and the output pump 10 sprays the water of the external cooling pool into the rotary drum 4 and onto the filter holes of the outer wall of the rotary drum 4 through the nozzle 1 12 and the nozzle 2 19 respectively, so as to cool the plastic particles located in the rotary drum 4 and at the same time flush the plastic particles adhered to the inner wall of the rotary drum 4 to make them fall, and at the same time fully cool the plastic particles attached to the inner wall of the rotary drum 4.

[0032] An electric push rod 15 is fixedly installed on one side of the outer wall of the vertical plate 5. The telescopic end of the electric push rod 15 is fixedly connected with a rack 16, which is meshed with a fan-shaped toothed plate 17. A connecting pipe 22 is connected between the arc tube 18 and the conveying pipe 7. An arc strip 21 that fits the inner wall of the fan-shaped toothed plate 17 is fixedly connected to the surface of the fixed plate 20. The fixed plate 20 is provided with a limiting groove for the horizontal movement of the rack 16. A slider located in the limiting groove is fixedly connected to the back of the rack 16.

[0033] A receiving hopper 11 is fixedly connected to the top of the installation box 1. The receiving hopper 11 passes through the installation box 1 and is connected with a discharge pipe 14. The discharge pipe 14 is bent and extends into the rotary drum 4. The receiving hopper 11 is connected to the discharge port of the plastic granulator, which can facilitate the transportation of the plastic granules into the rotary drum 4 and realize rapid cooling of the plastic granules.

[0034] A gear ring 8 is fixedly connected to the outer contour of the rotating drum 4, and the gear ring 8 is meshed with a gear 9. A connecting seat 30 is fixedly connected to one side of the bottom of the installation box 1, and a reduction motor for driving the gear 9 to rotate is fixedly installed on the connecting seat 30. When the reduction motor is started, the rotating drum 4 can be driven to rotate. Through the rotation of the rotating drum 4 and the coordinated spiral blades 13, the plastic particles located in the rotating drum 4 can be transported, and the plastic particles are discharged along the rotating drum 4 from the end away from the discharge pipe 14.

[0035] A mounting seat 25 is fixedly installed on the upper surface of the connecting seat 30, and the mounting seat 25 is rotatably connected to two support rollers 26 that support the rotating drum 4. The connecting seat 30 and the mounting seat 25 are provided with two support rollers 26 that are respectively located on both sides of the collecting box 2. The support rollers 26 are rotatably connected to the rotating drum 4 to reduce the friction when driving the rotating drum 4 to rotate, so that the rotating drum 4 can rotate stably, which is convenient for conveying the plastic particles located in the rotating drum 4.

[0036] Example 2: Please refer to Figure 1-Figure 7 As shown, a rotary plastic particle discharging and cooling device of the present embodiment has filter holes on its outer contour located in the drying box 3, a cavity is provided in the drying box 3, a hot air blower 23 is fixedly installed on the outer wall of the drying box 3, and a vent 24 is fixedly installed on the side of the outer wall of the drying box 3 away from the hot air blower 23. The vent 24 is started to blow hot air into the rotary drum 4, so as to dry the plastic particles in the rotary drum 4 and evaporate the moisture on the surface of the plastic particles, so as to facilitate the subsequent collection and treatment thereof;

[0037] There are multiple ventilation holes 24, and the rotary drum 4 in the drying box 3 has a sufficient length, so as to ensure that the plastic particles in the rotary drum 4 have enough time to be dried. Compared with the traditional drying on the conveyor belt, the plastic particles are stationary or move relatively slowly, and the contact between the hot air and the material is not sufficient, resulting in low drying efficiency or uneven drying. The rotary drum 4 is used for conveying, and the plastic particles are constantly tumbling and moving in the rotary drum 4, which further enables the hot air to evenly contact various parts of the material, which helps to improve the drying efficiency and ensure the uniformity of the material drying.

[0038] A diverter box 27 is fixedly connected to the inner wall of the drying box 3. A connection port 29 connected to the output end of the hot air blower 23 is provided on the surface of the diverter box 27. A plurality of partition plates 28 are fixed in the connection port 29. The partition plates 28 are distributed in a fan shape. An opening is provided at one end of the diverter box 27 away from the hot air blower 23. The hot air blown out of the diverter box 27 can be dispersed toward the rotary drum 4 through the opening, so that the hot air is distributed more evenly, thereby ensuring the rapid drying operation of the plastic particles in the rotary drum 4 after cooling.

[0039] Combining the first and second embodiments, it can be known that by setting a cooling mechanism, the rotation of the rotary drum 4 cooperates with the spiral blades 13 inside it, the plastic particles continuously roll and move in the rotary drum 4, and cooperate with the conveying pipe 7 and the arc tube 18 for conveying and spraying. The nozzle 12 and the nozzle 2 19 are respectively sprayed on the filter holes in the rotary drum 4 and the outer wall of the rotary drum 4, so as to cool the plastic particles in the rotary drum 4, thereby achieving sufficient cooling of the plastic particles;

[0040] After cooling, the plastic particles enter the drying box 3 for drying operation, realizing continuous processing of cooling and drying and improving production efficiency. The diverter box 27 and the partition plate 28 arranged in the drying box 3 further optimize the distribution of hot air, so that the hot air is evenly dispersed in the diverter box 27 and blown toward the rotating drum 4 through the opening, ensuring that the hot air can evenly contact various parts of the plastic particles, improving the drying efficiency and uniformity. At the same time, the plastic particles continue to roll and move in the rotary drum 4, further enabling the hot air to evenly contact various parts of the material, helping to improve the drying efficiency and ensure the uniformity of material drying.
