[0013] Compared with the prior art, in the PVC particle plastic drying device provided by this solution, the oven, as the core container of the entire drying system, provides a closed heating environment for the PVC particle plastic, ensuring the stability and controllability of the drying process. The optimization of its internal structure, such as the setting of the material guiding mesh plate, helps the uniform distribution of hot air and the uniform heating of the particles, thereby improving the drying efficiency. The material guiding mesh plates are fixedly installed on the inner wall of the oven. These material guiding mesh plates not only play a role in supporting the PVC particle plastic but also effectively prevent uneven drying caused by particle accumulation. Their layout and design contribute to the penetration of hot air and the tumbling of particles, further promoting the drying effect. The inclined plate is installed on the inner wall of the bottom of the oven. Through the design of its inclination angle, it can guide the dried PVC particle plastic to smoothly slide out of the oven, facilitating subsequent collection and processing. This design reduces manual intervention and improves the degree of production automation. The hot air mechanism located at the bottom of the oven is responsible for injecting hot air into the oven interior to provide the necessary heat for drying the PVC particle plastic. By precisely controlling the temperature, air volume, and air velocity of the hot air, precise regulation of the drying process can be achieved, ensuring the drying quality of the PVC particle plastic. The movable support mechanism installed at the bottom of the oven provides stable support for the oven and also has a movable function. It drives the oven and multiple material guiding mesh plates to vibrate horizontally with the vibration mechanism. The vibration mechanism drives the oven and multiple material guiding mesh plates to vibrate horizontally, which helps the PVC particle plastic to continuously roll downward along the multiple material guiding mesh plates. The harmful gas adsorption mechanism installed on the top of the oven adsorbs and processes the harmful gases that may be generated during the drying process of the PVC particle plastic. This environmental protection design effectively reduces the environmental pollution during the drying process and protects the health and safety of production personnel;

[0014] In summary, the PVC particle plastic drying device in the present invention achieves efficient and environmentally friendly drying effects through its unique structure and design, improves production efficiency and product quality, and at the same time reduces the impact on the environment.
