[0001] The utility model relates to the technical field of production and processing of plastic particles, in particular to a drying and dehumidifying device for production and processing of plastic particles. Background Art

[0002] In the subsequent processing of plastic pellets, such as injection molding and extrusion, there are strict requirements on the moisture content of plastic pellets. Excessive moisture content will cause many problems in the processing process. During injection molding, moisture will turn into water vapor at high temperature, causing defects such as bubbles and silver streaks in plastic products, seriously affecting the appearance and quality of the products. During the extrusion process, moisture will cause instability of the plastic melt, resulting in uneven size of the extrudate and even broken strips. Therefore, a drying and dehumidification device for the production and processing of plastic pellets is needed.

[0003] The existing drying and dehumidifying device for producing and processing plastic particles has the problems of being unable to evenly stir the plastic particles, having poor drying and dehumidifying effects, and being unable to prevent dust during operation. Therefore, a drying and dehumidifying device for producing and processing plastic particles is urgently needed. Utility Model Content

[0006] The inner wall of the cover plate is installed with a breathable net, the inner wall of the heating chamber is installed with a storing chamber, the top of the support frame is installed with an air duct, the outer wall of the air duct is installed with an air pressure pump, the outer wall of the air duct is installed with a sedimentation chamber, and the bottom of the support frame is installed with a dustproof plate.

[0007] A temperature controller is installed on the side wall of the heating chamber, a limiting frame is installed on the bottom of the heating chamber, a power motor is installed on the bottom of the limiting frame, and a fan blade is installed on the top of the power motor.

[0008] Preferably, the support frame and the stirring blade are movably connected, and the inner wall of the stirring blade is of open-hole design.

By starting the air pressure pump, the dust is drawn into the sedimentation bin through the breathable net and the air duct for sedimentation and centralized treatment. The dust-proof plate is provided to block and seal the dust, thereby preventing dust from being raised and workers from inhaling a large amount of dust, which may lead to pneumoconiosis. At the same time, the cleanliness of the on-site processing environment is improved.

[0016] 3. The utility model is equipped with a temperature controller, a limit frame, a power motor and fan blades. The temperature controller controls the interior of the heating chamber to reach an appropriate temperature.
