Different types of plastics have different molecular structures and properties. Plastic processing air dryer is a device used to remove moisture or volatile organic compounds from plastic products. It is widely used in the plastic production and processing industry to ensure the quality of finished products, reduce energy consumption and improve production efficiency.

The utility model includes an air-drying barrel and an electric control box, the air-drying barrel is provided with a polarization mechanism inside, the polarization mechanism includes a sieve plate, a mounting box is provided on one side of the air-drying barrel, a motor is provided inside the mounting box, a polarization rod is provided at the output end of the motor, and a polarization block is provided on the polarization rod. The utility model uses the sieve plate, the motor, the polarization rod and the polarization block. First, plastic particles are put into the air-drying barrel through the feed port, and then the fan and the motor are started. The motor drives the polarization rod and the polarization block to rotate, and the collision of the polarization block with the sieve plate causes the plastic particles on the sieve plate to vibrate, so as to avoid the consequences of the plastic particles melting and sticking due to excessive temperature. At the same time, the heating efficiency of the air-drying machine can be improved, the temperature in the air-drying barrel can be increased, and the evaporation of water on the surface of the plastic particles can be accelerated. However, this patent only solves the problem of passing through a sieve plate, a motor, a polarization rod and a polarization block. First, the plastic particles are placed into the air-drying barrel through the feed port, and then the fan and the motor are started. The motor drives the polarization rod and the polarization block to rotate, and the collision of the polarization block with the sieve plate causes the plastic particles on the sieve plate to vibrate, thereby avoiding the consequences of the plastic particles melting and sticking together due to excessive temperature. At the same time, the heating efficiency of the air dryer can be improved, the temperature in the air-drying barrel can be increased, and the evaporation of moisture on the surface of the plastic particles can be accelerated. However, the problem that vibration cannot evenly heat each bucket of the plastic particles can be solved, so that some plastics cannot be completely dried, affecting the drying efficiency of the plastic processing air dryer.

The U-shaped bracket 8 is attached to the inner wall of the drying barrel 1 to break up the corner plastic. Since the inclined plate 9 is inclined inside the drying barrel 1, it can also break up the plastic in the middle part. Then, the solenoid valve 12 can be opened to discharge the plastic through the discharge port 11.
