Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a drying device for the production of modified plastic particles. Background Technology

[0002] Plastic drying is a crucial step in plastic processing. Its purpose is to remove moisture from plastic granules, preventing defects such as bubbles, silver streaks, and shrinkage cavities from occurring during subsequent molding processes. This ensures the quality and performance of plastic products. Drying effectively removes moisture from plastic granules, ensuring the stability of subsequent molding processes and product quality.

[0003] When drying plastics, a drying oven is often used for heating and drying. The plastics are transported through the drying oven by a conveyor belt to achieve the purpose of drying. The drying oven is usually a long and narrow structure, which occupies a large area. Furthermore, the drying in the drying oven mainly uses high temperature to evaporate the moisture on the surface of the plastic. There is no heat recovery structure. Heating equipment is needed to continuously maintain the internal temperature in order to operate stably, which consumes relatively a lot of energy. Utility Model Content

[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: it includes a disc drying box 1, which has an annular cavity. The annular cavity is divided into a feeding area 11, a drying area 12, and a discharge area 13. A discharge trough 4 is provided at the bottom of the annular cavity and at a position corresponding to the discharge area 13. A mesh plate 33 is fixed in the annular cavity and at a position corresponding to the feeding area 11 and the drying area 12. A heating rod 32 is fixed in the annular cavity and below the mesh plate 33. An installation hole 3 is provided at the bottom of the annular cavity and at a position corresponding to the drying area 12. A fan 31 is fixed in the installation hole 3. A pushing component is provided in the annular cavity and above the mesh plate 33. An upper cover 2 is fixed at the top of the disc drying box 1. A heat recovery component is provided between the upper cover 2 and the bottom of the disc drying box 1. A feeding hopper 9 is fixed at the top of the upper cover 2 and at a position corresponding to the feeding area 11. A support frame 14 is fixed around the bottom of the disc drying box 1.

[0018] The feeding assembly includes a rotating plate 5 and a pusher plate 51. The rotating plate 5 is rotatably connected to the middle position inside the disc drying box. The inner side of the pusher plate 51 is fixed on the rotating plate 5 and located above the screen plate 33. The bottom of the pusher plate 51 is connected to the upper end of the screen plate 33. A drive motor 52 is fixed at the bottom of the disc drying box 1, and the output end of the drive motor 52 is fixed at the bottom of the rotating plate 5.

[0019] A temperature sensor is fixed inside the annular groove and located at the position of the drying zone 12. A control box is fixed outside the disc drying box 1. The temperature of the drying zone can be monitored by the temperature sensor to ensure that the temperature is within the predetermined range, thereby achieving the purpose of thorough drying. The heat recovery component includes an upper frame 6, a bottom frame 7 and a connecting pipe 8. The upper frame 6 is fixed to the upper end of the upper cover 2 and aligned with the exhaust hole above the drying zone 12. The bottom frame 7 is fixed to the bottom of the disc drying box 1 and aligned with the mounting hole 3. The connecting pipe 8 is fixed between the upper frame 6 and the bottom frame 7, and a desiccant filter element is installed inside the connecting pipe 8.

[0020] Working principle: First, connect the entire device to an external power source. Then, place the damp plastic raw material into the feeding hopper 9, allowing it to fall into the feeding area 11 within the annular cavity and onto the mesh plate 33. The output of the drive motor 52 then drives the rotating plate 5 to rotate, causing the pusher plate 51 to rotate circumferentially within the annular cavity. This pushes the plastic material onto the mesh plate 33. Upon entering the drying zone 12, the heating rod 32 raises the temperature of the drying zone 12. Finally, the fan 31 drives the airflow to quickly pass over the plastic surface, removing the moisture. The material evaporates rapidly to achieve the purpose of drying. Finally, the material is continuously pushed by the pusher plate 51 into the discharge area 13 and discharged through the discharge hole. The common long strip drying structure is designed as a disc conveyor, which can reduce the overall space occupation of the equipment. During the drying process, hot air and water vapor will enter the upper frame 6, and then pass through the connecting pipe 8 into the bottom frame 7, and finally be dried again by blowing air. When passing through the connecting pipe 8, the desiccant filter inside absorbs water vapor, ensuring that the dried hot air is recycled and reused, thus achieving the purpose of energy saving.
