Description

Technical Field

[0001] This utility model relates to the field of plastic granule production technology, specifically a dehumidification device for plastic granule production. Background Technology

[0002] As is well known, removing moisture from plastic granules is a crucial step in the production process. Traditional methods for dehumidifying plastic granules typically involve static drying ovens or simple stirring drying equipment.

[0003] Static drying ovens lack effective stirring devices, resulting in uneven heating of plastic granules during the drying process, which affects the dehumidification effect. This is especially true for plastic granules that are prone to clumping, which can create localized wet areas and affect the quality of the final product. Although simple stirring drying equipment can partially solve the clumping problem, insufficient stirring may still result in some areas of undried plastic granules, leading to low dehumidification efficiency. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dehumidification device for plastic granule production, comprising a processing box, a dehumidification cylinder, and a stirring device. Support legs are installed at the four corners of the bottom of the processing box. The dehumidification cylinder is rotatably installed inside the processing box. A feed pipe is installed at the top of the processing box. A feed inlet is opened at the top of the dehumidification cylinder. A discharge pipe is installed at the bottom of the dehumidification cylinder. Several filter holes are arranged in a ring on the outer wall of the dehumidification cylinder. Three sets of air outlet rings are installed on the inner wall of the processing box, and the three sets of air outlet rings are connected by a connecting pipe. Multiple air outlets are installed on the inner wall of each air outlet ring. An air inlet pipe is installed on the side wall of the processing box. An air heater is installed on the outer wall of the air inlet pipe, and a fan is installed at the end of the air inlet pipe. The stirring device includes a first motor, a stirring shaft, spiral blades, an eccentric shaft, a turntable, and a drive device. The first motor is installed on the top wall of the inner cavity of the processing box. The output end of the first motor is connected to the top wall of the dehumidification cylinder through a bearing and extends into its inner cavity to install the stirring shaft. The spiral blades are installed on the outer wall of the stirring shaft. The eccentric shaft is fixedly installed at the top of the dehumidification cylinder. An annular groove is opened at the top of the processing box. The turntable is fixedly installed through the annular groove at the top of the eccentric shaft. The turntable is driven by the drive device.

[0008] To facilitate the rotation of the turntable, this utility model is improved by including a driven bevel gear, a driving bevel gear, and a second motor in the driving device. The driven bevel gear is fixedly installed at the top of the turntable, and the driving bevel gear is meshed with one side of the driven bevel gear. The second motor is installed at the end of the driving bevel gear away from the driven bevel gear.

[0009] To ensure the stable installation of the second motor, this utility model is improved by installing a support block on the top of the processing box to support the second motor.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4A dehumidification device for plastic granule production includes a processing box 1, a dehumidification cylinder 2, and a stirring device. Support legs 3 are installed at the four corners of the bottom of the processing box 1. The dehumidification cylinder 2 is rotatably mounted inside the processing box 1. A feed pipe 4 is installed at the top of the processing box 1. A feed inlet 5 is opened at the top of the dehumidification cylinder 2. A discharge pipe 6 is installed at the bottom of the dehumidification cylinder 2. A plurality of filter holes 7 are arranged in a ring on the outer wall of the dehumidification cylinder 2. Three sets of air outlet rings 8 are installed on the inner wall of the processing box 1, and the three sets of air outlet rings 8 are connected by connecting pipes 9. Multiple air outlets 10 are installed on the inner wall of each air outlet ring 8. An air inlet pipe 11 is installed on the side wall of the processing box 1, and an air heater is installed on the outer wall of the air inlet pipe 11. The device 12 has a fan 13 installed at the end of the air inlet pipe 11. The stirring device includes a first motor 14, a stirring shaft 15, a spiral blade 16, an eccentric shaft 17, a turntable 18, and a drive device. The first motor 14 is installed on the top wall of the inner cavity of the processing box 1. The output end of the first motor 14 is connected to the top wall of the dehumidification cylinder 2 through a bearing and extends into its inner cavity to install the stirring shaft 15. The spiral blade 16 is installed on the outer wall of the stirring shaft 15. The eccentric shaft 17 is fixedly installed at the top of the dehumidification cylinder 2. An annular groove 19 is opened at the top of the processing box 1. The turntable 18 is fixedly installed at the top of the eccentric shaft 17 through the annular groove 19. The turntable 18 is driven by the drive device. In this embodiment, during operation, the material (plastic granules) enters the processing tank 1 through the feed pipe 4 at the top of the processing tank 1, and then enters the dehumidification cylinder 2 through the feed port 5 at the top of the dehumidification cylinder 2 (there is a small gap between the feed pipe 4 and the feed port 5, which does not affect the rotation of the dehumidification cylinder 2, but allows the material to enter the dehumidification cylinder 2 smoothly). The fan 13 draws in outside air through the air inlet pipe 11, and after being heated by the air heater 12, the hot air is evenly blown into the dehumidification cylinder 2 through multiple air outlets 10 on the three sets of air outlet rings 8 to dry the material. Then, the first motor 14 is started. After the first motor 14 starts, it drives the stirring shaft 15 to rotate. The spiral blades 16 installed on the outer wall of the stirring shaft 15 rotate accordingly, drying the material entering the dehumidification cylinder. The material inside the dehumidifier cylinder 2 is stirred to ensure even distribution. Simultaneously, the drive device rotates the eccentric shaft 17 at the top of the dehumidifier cylinder 2 in both forward and reverse directions, causing it to rotate along with the turntable 18. During rotation, the plastic granules are continuously exposed to fresh hot air, enhancing the heat exchange efficiency between the granules and the hot air and accelerating the evaporation of moisture. The rotation of the dehumidifier cylinder 2 reduces dead zones in the material, ensuring that all plastic granules receive the same treatment conditions and preventing the dehumidification effect from being affected by localized material accumulation. While the material is dried by hot air inside the dehumidifier cylinder 2, fine impurities in the plastic granules are filtered into the processing box 1. The dried material is then discharged through the discharge pipe 6 at the bottom of the dehumidifier cylinder 2.

[0025] In practical use, to further facilitate the rotation of the turntable 18, in this embodiment, the driving device includes a driven bevel gear 20, a driving bevel gear 21, and a second motor 22. The driven bevel gear 20 is fixedly installed at the top of the turntable 18. The driving bevel gear 21 is meshed with one side of the driven bevel gear 20. The second motor 22 is installed at the end of the driving bevel gear 21 away from the driven bevel gear 20. The second motor 22 serves as a power source. When it starts, it generates a rotational torque. The power of the second motor 22 is transmitted to the driving bevel gear 21 fixedly connected to it through its output shaft. The driving bevel gear 21 starts to rotate. The rotation of the driving bevel gear 21 will drive the driven bevel gear 20 meshing with it to rotate synchronously. The driven bevel gear 20 is fixedly installed at the top of the turntable 18. Therefore, when the driven bevel gear 20 rotates, it will drive the entire turntable 18 to rotate together, realizing the rotation operation of the turntable 18.

[0026] In actual use, to further ensure the stable installation of the second motor 22, in this embodiment, a support block 23 is installed on the top of the processing box 1 to support the second motor 22. The support block 23 can provide a stable foundation, making the second motor 22 more stable during operation and reducing displacement or shaking caused by vibration or movement.

[0027] In actual use, the plastic granules are further stirred. In this embodiment, multiple sets of stirring rods 24 are fixedly installed at both ends of the stirring shaft 15. Multiple sets of stirring rods 24 can increase the opportunity to contact the plastic granules, making the mixing between the granules more uniform and preventing insufficient mixing in some areas. The rapid rotation of the stirring rods 24 can effectively break the aggregation between the granules, so that each granule has the opportunity to come into contact with the hot air and improve the drying efficiency.

[0028] In actual use, to further ensure the stability and accuracy of the operation of the first motor 14 and the second motor 22, in this embodiment, both the first motor 14 and the second motor 22 are servo motors. Servo motors can control position, speed and torque with high precision. Servo motors adopt closed-loop control, which has good stability and can avoid problems such as stalling and vibration, thus ensuring the stability and accuracy of the operation of the first motor 14 and the second motor 22.

[0029] In actual use, to further facilitate the normal discharge of material from the discharge pipe 6, in this embodiment, the discharge pipe 6 extends through the bottom wall of the processing box 1, which facilitates the normal outward output of dried plastic granules from the discharge pipe 6.

[0030] In practical use, to further facilitate the discharge of filtered impurities, in this embodiment, a discharge pipe 25 is installed on the bottom wall of one end of the treatment box 1. The discharge pipe 25 can conveniently discharge impurities and waste generated during the filtration process from the treatment box 1, and the cleaning work can be completed without disassembling the entire device, saving time and labor.

[0031] In actual use, the feeding of materials is further guided. In this embodiment, a guide box 26 is installed at the top of the feed pipe 4. The guide box 26 can serve as a guide device for the material to enter the feed pipe 4, so that the material can enter the feed pipe 4 more smoothly. This can improve the feeding speed and ensure that the material can enter the processing stage quickly and smoothly.
