Description

Technical Field

[0001] This utility model belongs to the field of plastic granule processing technology, specifically relating to a drying and dehumidification device for plastic granule production and processing. Background Technology

[0002] In the subsequent processing of plastic granules, such as injection molding and extrusion, the moisture content of the raw materials is strictly limited. Excessive moisture content can lead to a series of processing defects: during injection molding, residual moisture vaporizes at high temperatures, causing problems such as silver streaks and bubbles on the surface of the product, severely affecting its appearance and mechanical properties; during extrusion, moisture causes melt fluctuations, unstable extrudate dimensions, and even breakage, reducing production efficiency. Therefore, effective drying and dehumidification treatment must be performed on plastic granules before processing.

[0003] A commonly used drying device employs external air circulation combined with mechanical stirring to accelerate drying. However, during the rapid drying and stirring process, a large amount of plastic dust is easily generated. These fine particles diffuse into the workshop environment with the exhaust airflow, not only polluting the air quality but also endangering the respiratory health of the operators.

[0004] Chinese utility model patent CN223223681U discloses a drying and dehumidifying device for plastic granule production and processing, belonging to the field of plastic granule production and processing technology. The device includes a heating chamber with a cover plate installed on top. This utility model utilizes a rotary motor, a stirring blade, and a holding chamber. The rotary motor drives the stirring blade to rotate at a uniform speed, stirring the plastic granules inside the holding chamber to prevent them from accumulating and sticking together, thus preventing internal moisture from evaporating. The outer wall of the holding chamber has fine perforations, allowing excess moisture to drain. A temperature controller, a limit frame, a power motor, and fan blades are included. The temperature controller controls the internal temperature of the heating chamber to reach a suitable level, while the power motor drives the fan blades to rotate rapidly, accelerating air circulation within the heating chamber. This rapid circulation of hot air quickly dries and dehumidifies the plastic granules, improving processing efficiency. Although the dust filter can filter the dust generated during the drying process, it cannot filter all the dust. Moreover, as the usage time increases, the effectiveness of the dust filter weakens, causing dust to be blown into the processing workshop, resulting in a decline in the air quality in the processing workshop and endangering the health of workers. Utility Model Content

[0005] The purpose of this invention is to provide a drying and dehumidification device for the production and processing of plastic granules, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drying and dehumidification device for plastic granule production and processing, comprising a frame, on which a dust filter, a compressor dehumidifier, and a heating device are fixedly installed. The dust filter is connected to the compressor dehumidifier via a first pipe, and the compressor dehumidifier is connected to the heating device via a second pipe. A sealing shell is fixedly installed on the frame, and the sealing shell has a processing window. A sealing door is movably installed on the processing window via a first hinge. A stirring mechanism, an air inlet connection mechanism, and an exhaust connection mechanism are fixedly installed on the frame. The stirring mechanism includes a motor, a first roller shaft, a second roller shaft, and a stirring tank. The drive end of the motor is connected to the first roller shaft and the second roller shaft via a belt drive. The stirring tank is movably disposed between the first roller shaft and the second roller shaft. Ventilation plates are provided at both ends of the stirring tank. The stirring tank has a material inlet, and a material gate is fixedly installed on the material inlet. The air inlet connection mechanism is connected to the heating device via an air inlet pipe, and the exhaust connection mechanism is connected to the dust filter via an exhaust pipe.

[0007] Preferably, the intake connection mechanism and the exhaust connection mechanism are the same mechanism, both including a horn connector, a movable sleeve, a moving platform and a drive cylinder. The moving platform is movably mounted on the frame via a guide rail, and the moving platform is fixedly connected to the movable sleeve via a support plate.

[0008] Preferably, a baffle plate is fixedly installed inside the mixing tank.

[0009] Preferably, the material gate is fixedly connected to a connecting plate, and the connecting plate is fixedly connected to the mixing tank by quick-release bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] In this invention, the mixing tank of the mixing mechanism is used to hold the plastic granules to be dried. Ventilation plates are provided at both ends of the mixing tank, and are fixed by a first roller shaft and a second roller shaft. A motor drives the first and second roller shafts to rotate via a belt, thereby rotating the mixing tank and causing the plastic granules to be dried inside to tumble thoroughly, thus improving drying efficiency.

[0012] Hot air is generated by a heating device, delivered to the air inlet connection mechanism via an air inlet pipe, and then enters the mixing tank through a ventilation plate on one side to dry the plastic granules. The humid, hot air generated during the drying process is discharged from the ventilation plate on the other side of the mixing tank, enters the exhaust connection mechanism, and then is guided through an exhaust pipe to a dust filter for filtration. The filtered humid air enters a compressed dehumidifier for dehumidification, and then is sent back to the heating device for reheating, forming a closed-loop drying system.

[0013] In addition, the frame is equipped with a sealed shell to effectively prevent dust from escaping into the workshop. The system uses an internal air circulation method to process plastic granules, avoiding the emission of plastic dust into the processing workshop and ensuring a clean air environment.

[0021] 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.

[0022] Example 1:

[0023] This utility model provides a drying and dehumidification device for plastic granule production and processing, including a frame 1. The frame 1 is fixedly equipped with a dust filter 2, a compressor dehumidifier 3, and a heating device 4. The dust filter 2 is connected to the compressor dehumidifier 3 via a first pipe 5, and the compressor dehumidifier 3 is connected to the heating device 4 via a second pipe 6. A sealing shell 7 is fixedly installed on the frame 1, and the sealing shell 7 has a processing window 8. A sealing door 10 is movably installed on the processing window 8 via a first hinge 9. A stirring mechanism 11, an air inlet connection mechanism 12, and an exhaust connection mechanism are also fixedly installed on the frame 1. The mixing mechanism 11 includes a motor 14, a first roller 15, a second roller 16, and a mixing tank 17. The drive end of the motor 14 is connected to the first roller 15 and the second roller 16 via a belt 18. The mixing tank 17 is movably disposed between the first roller 15 and the second roller 16. Ventilation plates 19 are provided at both ends of the mixing tank 17. The mixing tank 17 has a material inlet 20, and a material gate 21 is fixedly installed at the material inlet 20. The air inlet connection mechanism 12 is connected to the heating device 4 via an air inlet pipe 22, and the exhaust connection mechanism 13 is connected to the dust filter device 2 via an exhaust pipe 23. The air inlet connection mechanism 12 and the exhaust connection mechanism 13 are the same mechanism, both including a horn connector 24, a movable sleeve 25, a moving platform 26, and a drive cylinder 27. The moving platform 26 is movably mounted on the frame 1 via a guide rail 28, and the moving platform 26 is fixedly connected to the movable sleeve 25 via a support plate 29. A lever 30 is fixedly installed inside the mixing tank 17. The material gate 21 is fixedly connected to a connecting plate 31, and the connecting plate 31 is fixedly connected to the mixing tank 17 by quick-release bolts 32.

[0024] Through the above technical solution, the mixing tank 17 of the mixing mechanism 11 of this utility model is used to hold dried plastic granules. Both ends of the mixing tank 17 are provided with ventilation plates 19. The first roller shaft 15 and the second roller shaft 16 cooperate to fix the mixer. The motor 14 drives the first roller shaft 15 and the second roller shaft 16 to rotate, thereby driving the mixing tank 17 to rotate, so that the dried plastic granules in the mixing tank 17 tumble, improving the drying efficiency. Hot air is generated from the heating device 4 and blown into the air inlet connection mechanism 12 through the air inlet pipe 22. The air inlet connection mechanism 12 is connected to the ventilation plate 19 on one side of the mixing tank 17, and the hot air enters from the ventilation plate 19. Inside the mixing tank 17, the plastic granules are dried. The hot air containing moisture is then blown into the exhaust connection mechanism 13 from the other side of the mixing tank 17, and enters the dust filter device 2 through the exhaust pipe 23. After being filtered, the hot air containing moisture enters the compressor dehumidifier 3 for dehumidification. The dehumidified air then enters the heating device 4 for heating, and the heated air is then reintroduced into the mixing tank 17. This cycle of drying continues. A sealing shell 7 is installed outside the frame 1 to prevent dust from escaping into the workshop. The internal air circulation method is used to dry the plastic granules, preventing plastic dust from being blown into the processing workshop and preventing air pollution in the workshop.

[0025] Example 2:

[0026] In this embodiment, the frame 1 serves as the overall support structure, and a dust filter 2, a compressor dehumidifier 3, and a heating device 4 are fixedly installed thereon. The dust filter 2 is connected to the compressor dehumidifier 3 via a first pipe 5, and the compressor dehumidifier 3 is connected to the heating device 4 via a second pipe 6, forming a basic airflow processing path. A sealing shell 7 is fixed to the outside of the frame 1. The sealing shell 7 has a processing window 8, and a sealing door 10 is movablely installed in the processing window 8 via a first hinge 9, facilitating operators to enter the equipment for maintenance or adjustment. The design of the sealing shell 7 effectively isolates the internal working environment from the external workshop, preventing dust and moisture leakage.

[0027] The mixing mechanism 11 is mounted on the frame 1 and includes a motor 14, a first roller 15, a second roller 16, and a mixing tank 17. The drive end of the motor 14 is connected to the first roller 15 and the second roller 16 via a belt drive system 18, enabling them to rotate synchronously. The mixing tank 17 is movably positioned between the first roller 15 and the second roller 16. The rotation of the rollers drives the mixing tank 17 to rotate itself, thereby causing the plastic granules inside the tank to tumble evenly and improving drying efficiency. Ventilation plates 19 are provided at both ends of the mixing tank 17 to allow hot air to enter and moisture to escape. The mixing tank 17 is provided with a feed inlet 20, and a feed gate 21 is fixedly installed on the feed inlet 20 to facilitate the loading and unloading of plastic granules.

[0028] The air intake connection mechanism 12 and the exhaust connection mechanism 13 are fixed to the frame 1 and are connected to the heating device 4 and the dust filter device 2 respectively through the air intake pipe 22 and the exhaust pipe 23. The air intake connection mechanism 12 is responsible for delivering heated dry air to the ventilation plate 19 on one side of the mixing tank 17, so that it enters the tank to heat and dehumidify the plastic granules. The exhaust connection mechanism 13 collects air containing moisture and dust from the ventilation plate 19 on the other side of the mixing tank 17 and guides it back to the dust filter device 2 through the exhaust pipe 23. When it is necessary to remove the mixing tank 17 for cleaning or replacement, the air intake connection mechanism 12 and the exhaust connection mechanism 13 can be retracted and separated from the mixing tank 17 for easy operation.

[0029] When the entire device is in operation, hot air is generated from the heating device 4, enters the mixing tank 17 through the air inlet pipe 22 and the air inlet connection mechanism 12, and dries the plastic granules. Moisture and dust generated during the drying process enter the dust filter device 2 through the exhaust connection mechanism 13 and the exhaust pipe 23. After the dust is filtered out, the humid air enters the compressed dehumidifier 3 for dehumidification, and then is sent back to the heating device 4 for heating, forming a closed-loop system. This design avoids the emission of plastic dust into the workshop environment, ensuring clean air quality. Simultaneously, the rotation of the mixing tank 17 and the circulation of hot air achieve a highly efficient and uniform drying effect.

[0030] Example 3:

[0031] In this embodiment, the air intake connection mechanism 12 and the exhaust connection mechanism 13 have the same structure, both including a horn connector 24, a movable sleeve 25, a moving platform 26, and a drive cylinder 27. A guide rail 28 is mounted on the frame 1, and the moving platform 26 is slidably connected via the guide rail 28. The moving platform 26 is fixedly connected to the movable sleeve 25 via a support plate 29. One end of the horn connector 24 of the air intake connection mechanism 12 is connected to the air intake pipe 22, and one end of the horn connector 24 of the exhaust connection mechanism 13 is connected to the exhaust pipe 23. The other end of the horn connector 24 is designed to dock with the movable sleeve 25. During device operation, the drive cylinder 27 extends, pushing the moving platform 26 to move along the guide rail 28, causing the movable sleeve 25 to tightly dock with the ventilation plate 19 of the mixing tank 17, thereby forming a closed airflow channel and achieving internal circulation airflow for drying the plastic particles. After the drying operation is completed, the drive cylinder 27 retracts, pulling the moving table 26 to move in the opposite direction, so that the movable sleeve 25 is separated from the ventilation plate 19 of the mixing tank 17, making it easier for the operator to remove the mixing tank 17 from the device for subsequent operations.

[0032] In this embodiment, the stirring mechanism 11 includes a motor 14, a first roller shaft 15, a second roller shaft 16, and a stirring tank 17. The motor 14 drives the first roller shaft 15 and the second roller shaft 16 to rotate synchronously via a belt 18. The stirring tank 17 is positioned between the first roller shaft 15 and the second roller shaft 16, and the rotation of the roller shafts drives the stirring tank 17 to rotate. Ventilation plates 19 are provided at both ends of the stirring tank 17 for airflow. A material inlet 20 is provided on the stirring tank 17, and an openable and closable material gate 21 is installed to facilitate the loading and unloading of plastic granules. The entire stirring mechanism 11 is mounted on the frame 1 and works in conjunction with the air inlet connection mechanism 12 and the exhaust connection mechanism 13 to achieve uniform drying of the plastic granules.

[0033] During the drying and dehumidification process, the hot air generated by the heating device 4 is delivered to the air inlet connection mechanism 12 through the air inlet pipe 22, and then enters the interior of the mixing tank 17 through the connection between the movable sleeve 25 and the ventilation plate 19 on one side of the mixing tank 17, heating and drying the plastic granules. The mixing tank 17 rotates continuously under the drive of the motor 14, causing the plastic granules inside the tank to tumble fully, improving the uniformity and efficiency of drying. The hot and humid airflow generated during drying is discharged from the ventilation plate 19 on the other side of the mixing tank 17, enters the exhaust pipe 23 through the exhaust connection mechanism 13, and then is introduced into the dust filter device 2 for dust filtration.

[0034] The filtered humid air enters the compressor dehumidifier 3 for dehumidification. After removing moisture from the air, it is then sent back to the heating device 4 for heating, forming a complete internal circulation drying system. This closed-loop design effectively prevents plastic dust leakage and ensures the air quality of the production environment. The sealing shell 7 on the outside of the frame 1 further enhances the dustproof effect. The processing window 8 on the sealing shell 7 is fitted with a sealing door 10 via a hinge, facilitating equipment maintenance and operation.

[0035] This drying and dehumidifying device achieves efficient drying of plastic granules through the organic combination of an internal circulating airflow system and mechanical stirring, while effectively controlling dust pollution during the production process. The air inlet connection mechanism 12 and the exhaust connection mechanism 13 adopt the same modular design, simplifying the equipment structure and improving its reliability and ease of maintenance. The entire device operates stably, with significant drying effects, meeting the stringent requirements for raw material moisture content in plastic granule production and processing.

[0036] Example 4:

[0037] In this embodiment, a dust filter 2, a compressor dehumidifier 3, and a heating device 4 are fixedly installed on the frame 1. The dust filter 2 is connected to the compressor dehumidifier 3 via a first pipe 5, and the compressor dehumidifier 3 is connected to the heating device 4 via a second pipe 6. A sealing shell 7 is also fixedly installed on the frame 1. The sealing shell 7 has a processing window 8, and a sealing door 10 is movably installed on the processing window 8 via a first hinge 9. A stirring mechanism 11, an air inlet connection mechanism 12, and an exhaust connection mechanism 13 are fixedly installed on the frame 1. The stirring mechanism 11 includes a motor 14, a first roller shaft 15, a second roller shaft 16, and a stirring tank 17. The drive end of the motor 14 is driven to connect the first roller shaft 15 and the second roller shaft 16 via a belt 18. The stirring tank 17 is movably disposed between the first roller shaft 15 and the second roller shaft 16. Ventilation plates 19 are provided at both ends of the stirring tank 17, and the stirring tank 17 has a material inlet 20, on which a material gate 21 is fixedly installed. The air inlet connection mechanism 12 is connected to the heating device 4 via the air inlet pipe 22, and the exhaust connection mechanism 13 is connected to the dust filter device 2 via the exhaust pipe 23. The material inlet 20 facilitates the feeding or removal of plastic granules into the mixing tank 17. The air inlet connection mechanism 12 and the exhaust connection mechanism 13 are used to mate with the ventilation plates 19 at both ends of the mixing tank 17. When it is necessary to remove the mixing tank 17, they retract and separate from the mixing tank 17.

[0038] In this embodiment, a baffle plate 30 is fixedly installed inside the mixing tank 17. The motor 14 drives the first roller shaft 15 and the second roller shaft 16 to rotate, which in turn rotates the mixing tank 17. The baffle plate 30 inside the mixing tank 17 rotates accordingly, lifting the plastic granules. As it rotates, the baffle plate 30 tilts, and the plastic granules fall from one side of the baffle plate 30, improving drying efficiency. The design of the baffle plate 30 ensures that the plastic granules are continuously tumbled and lifted within the mixing tank 17, preventing granule accumulation and adhesion, ensuring that hot air can evenly contact the granule surface, and accelerating moisture evaporation. The tilt angle and rotation speed of the baffle plate 30 can be adjusted according to the type and humidity of the plastic granules to achieve the best drying effect. Through the continuous movement of the baffle plate 30, the plastic granules form a circulating flow within the mixing tank 17, which not only improves heat exchange efficiency but also prevents localized overheating or uneven drying.

[0039] During the drying process, hot air is generated by the heating device 4, delivered to the air inlet connection mechanism 12 through the air inlet pipe 22, and then enters the drum 17 through the ventilation plate 19 on one side to dry the plastic granules. The humid hot air generated during drying is discharged from the ventilation plate 19 on the other side of the mixing drum 17, enters the exhaust connection mechanism 13, and then is introduced into the dust filter device 2 for filtration through the exhaust pipe 23. The filtered humid air enters the compressor dehumidifier 3 for dehumidification, and after removing moisture, it is sent back to the heating device 4 for heating, forming a closed-loop drying system. This circulation method not only saves energy but also avoids the emission of plastic dust into the workshop environment, ensuring the air quality in the operating area.

[0040] The design of the sealed shell 7 further enhances the dustproof performance of the device, preventing dust from escaping during the drying process. The structure of the processing window 8 and the sealed door 10 facilitates the insertion and removal of plastic granules by operators, while ensuring that the device remains closed during the drying process. The stable operation of the stirring mechanism 11 relies on the coordinated work of the motor 14, the first roller 15, and the second roller 16, ensuring the smooth rotation of the stirring tank 17 and the effective agitation of the plastic granules by the turntable 30. The entire device integrates dust filtration, dehumidification, and heating functions, achieving efficient and environmentally friendly plastic granule drying, and is suitable for various plastic processing scenarios.

[0041] Example 5:

[0042] In this embodiment, the material gate 21 is fixedly connected to the connecting plate 31, and the connecting plate 31 is fixedly connected to the mixing tank 17 via quick-release bolts 32. This structural design makes the installation and disassembly of the material gate 21 simple and quick, facilitating cleaning or maintenance of the interior of the mixing tank 17 by operators. During the drying process of plastic granules, the mixing tank 17 needs to be opened periodically to load raw materials or remove finished products; the application of quick-release bolts 32 significantly improves the efficiency of this step. The connecting plate 31, as a transition component between the material gate 21 and the mixing tank 17, ensures the stability and sealing of the connection structure, preventing material leakage or dust leakage during the mixing process.

[0043] The quick-release bolt 32 works as follows: when the material gate 21 needs to be opened, the operator only needs to loosen the bolt to remove the material gate 21 along with the connecting plate 31; when closing, the operation is reversed: align the connecting plate 31 with the installation position of the mixing tank 17 and tighten the bolt to complete the fixation. This design avoids the tedious process of traditional bolts requiring multiple rotations, reducing operation time and labor intensity. In the drying process of plastic granules, the mixing tank 17 needs to be opened and closed frequently to match the production rhythm. The quick-release structure can effectively adapt to this requirement and ensure the continuity of the production process.

[0044] In this embodiment, the connection between the connecting plate 31 and the material gate 21 is fixedly connected by welding or integral molding to ensure no relative displacement between them, thereby maintaining the structural integrity of the material gate 21 during the mixing process. The quick-release bolts 32 are standard parts with anti-loosening function and can remain tight under vibration. When the mixing tank 17 rotates by the roller under the drive of the motor 14, the material gate 21 needs to withstand the impact and friction of the internal material. The reinforcing effect of the connecting plate 31 and the reliable fixation of the quick-release bolts 32 together ensure the durability of the material gate 21 in long-term use.

[0045] From a functional perspective, the material gate 21 achieves a modular design through the combination of the connecting plate 31 and the quick-release bolts 32. This facilitates the individual replacement or maintenance of the material gate 21 components without affecting the overall structure of the mixing tank 17. During the operation of the drying device, the mixing tank 17 needs to remain sealed to maintain the pressure balance of the hot air circulation system. The quick-release connection ensures sealing while providing necessary flexibility. After the plastic granules have finished drying, the operator can quickly open the material gate 21 to unload the material and close it promptly to prepare for the next batch, effectively shortening the equipment's downtime.

[0046] The material gate 21 connection structure in this embodiment also considers safety factors. The quick-release bolts 32 can be operated without special tools, reducing the risk of accidents caused by improper tool use. During maintenance, the disassembled material gate 21 and connecting plate 31 can be cleaned or inspected as independent units, avoiding interference with other components of the mixing tank 17. The overall design demonstrates how to improve operational convenience and maintenance efficiency in plastic granule drying equipment through simple mechanical connections, without sacrificing the core performance of the equipment.
