Description

Technical Field

[0001] This utility model relates to the field of plastic granule cooling and drying technology, and in particular to a cooling and drying device for a plastic granule extrusion granulator. Background Technology

[0002] A plastic granulator is a mechanical device that processes plastic raw materials (such as waste plastics, plastic powders, or plastic granules) into uniform plastic granules through processes such as heating, melting, extrusion, cooling, and pelletizing. This equipment is widely used in plastic recycling, modified plastics production, and raw material preparation for plastic products, and is a key piece of equipment for achieving the recycling and efficient processing of plastic resources. The cooling and drying system is an important component of the plastic granulator, directly affecting granule quality and production efficiency. By rationally selecting cooling and drying methods and optimizing equipment parameters, efficient, energy-saving, and stable granule production can be achieved.

[0003] A drying and cooling mechanism for a twin-screw granulator, with application number CN201922346270.9, includes a mounting plate with a U-shaped structure. Mounting mechanisms are located on both sides of the mounting plate. A drying and cooling box is positioned above the mounting plate, and a support mechanism connects the drying and cooling box to the mounting plate. The drying and cooling box contains a storage slot and a cooling chamber. A power supply and a cooling fan are respectively located within the storage slot and cooling chamber. A switch is fixed to the upper end of the drying and cooling box and is electrically connected to the power supply. The output of the power supply is electrically connected to the input of the cooling fan. Two clamping mechanisms are located on both sides of the cooling fan. A slot communicating with the cooling chamber is located at the upper end of the drying and cooling box. This drying and cooling mechanism for the twin-screw granulator is easy to install and disassemble, improving efficiency. It also provides good vibration damping, preventing the cooling fan from vibrating and loosening during operation, thus improving the stability of the cooling fan.

[0004] This device significantly improves efficiency thanks to its excellent shock absorption performance and efficient operating mechanism. However, in practical applications, its internal material handling process is cumbersome, its operating mode lacks flexibility, its adjustment mechanism is unable to meet diverse functional requirements, and it is difficult to adapt to complex and ever-changing production scenarios, exhibiting obvious shortcomings in practicality and versatility.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1-6 As shown, this embodiment provides a cooling and drying device for a plastic granule extrusion granulator, including a cooling and drying cylinder 1, which serves as the core main body of the device and provides space for cooling and drying plastic granules. A flow-guiding funnel 2 is provided at the lower end of the cooling and drying cylinder 1 to collect the cooled and dried plastic granules for subsequent collection and discharge operations. A drive mounting chamber 3 is fixedly installed on the outside of the flow-guiding funnel 2 to accommodate and support the operation of the exhaust structure 4. The exhaust structure 4 is rotatably installed inside the drive mounting chamber 3, and its main function is to promote gas exchange between the inside of the device and the outside. A vortex electric heater 5 is designed inside the drive mounting chamber 3 to play an auxiliary heating role in the cooling and drying process of plastic granules. An input funnel 6 is fixedly welded to the upper end of the cooling and drying cylinder 1 to facilitate the smooth pouring of hot and humid plastic granules into the cooling and drying cylinder 1. At the same time, its shape design also helps to guide the plastic granules to be evenly distributed in the cooling and drying cylinder 1, improving the uniformity of cooling and drying. A flow control structure 7 is provided on the outside of the input funnel 6 to control the airflow effect at the upper end of the device.

[0023] The drainage funnel 2 is fixedly welded to the lower end of the cooling and drying cylinder 1. The outer side of the drainage funnel 2 is evenly provided with exhaust drainage holes. When the exhaust structure 4 is in operation, it provides an additional channel for gas flow inside the device. On the one hand, this helps to accelerate the discharge of water vapor and volatile gases generated during the cooling and drying process, improving exhaust efficiency and making the air inside the device drier, which is beneficial for further drying of the plastic granules. On the other hand, the evenly distributed exhaust drainage holes allow the gas to form a relatively uniform airflow around the drainage funnel 2, preventing the plastic granules from accumulating or clogging at the drainage funnel 2 due to uneven airflow, ensuring that the plastic granules can be smoothly discharged through the drainage funnel 2.

[0024] The drive installation chamber 3 is located on the lower side of the drainage funnel 2. The lower side of the drive installation chamber 3 is evenly designed with protective vent holes. The drive installation chamber 3 provides a stable installation space for the exhaust structure 4, ensuring that the exhaust structure 4 can rotate and work stably. The evenly distributed vent holes can ensure air circulation inside and outside the drive installation chamber 3, so that the airflow generated by the exhaust structure 4 can be smoothly discharged, while fresh air from the outside can also enter, maintaining the freshness and suitable temperature of the air inside the drive installation chamber 3.

[0025] The exhaust structure 4 includes an exhaust fan blade 401, which is rotatably engaged with the output end of the drainage funnel 2. A spiral gear ring 402 is fixedly welded to the outer side of the exhaust fan blade 401. A drive linkage hole is opened on one side of the drive mounting chamber 3. An exhaust motor 403 is embedded in the drive linkage hole. A power gear is fixedly installed at the output end of the exhaust motor 403. The power gear meshes with the spiral gear ring 402. During the cooling and drying process of the plastic granules, the exhaust motor 403 continuously drives the exhaust fan blade 401 to rotate, generating a strong airflow to quickly expel water vapor, volatile gases, etc. from inside the device. At the same time, by adjusting the speed of the exhaust motor 403, the exhaust volume can be controlled according to the actual production needs to adapt to the cooling and drying requirements of different plastic granules.

[0026] The flow control structure 7 includes flow control holes 701, which are evenly distributed on the outer side of the flow funnel 2. A regulating shell 702 is rotatably mounted on the outer side of the flow funnel 2. The inner surface of the regulating shell 702 is in contact with the outer surface of the flow funnel 2. A regulating threaded ring 703 is fixedly welded to the upper end of the regulating shell 702. The output end of the flow funnel 2 is designed with a positioning thread. The regulating threaded ring 703 and the positioning thread are threadedly connected to each other. During the cooling and drying process of the plastic granules, the flow control structure 7 is adjusted in real time according to the actual situation. If the particle size, humidity and other parameters of the plastic granules change during the production process, the opening degree of the flow control holes 701 should be adjusted in time to ensure the stable flow of the plastic granules and improve the cooling and drying effect.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
