Specific embodiment mode
As shown in Figure 3, the plastic dryer in the present invention mainly includes a frame 2, a box 20 is provided on the outer cover of the frame 2, a drying cylinder 3 is provided in the frame 2, and a drying cylinder 3 is provided in the drying cylinder 3. The magnetron 4 is connected to the drying cylinder 3 through a communicating tube 40. Among them, one end of the connecting pipe 40 is provided with an air filter 41, the air filter 41 is provided with an air inlet 42, the other end of the connecting pipe 40 is connected with an air guide pipe 43, and a cone is provided near the inside of the drying cylinder 3 A storage cylinder 31 is provided below the drying cylinder 3, and an air filter 32 and a material guide tube 33 are respectively connected to the bottom of the storage cylinder 31, and a feeding material is provided above the drying cylinder 3. Tube 5, the feed tube 5 is provided with a feed tube 50 and an air guide tube 51, and an exhaust tube 6 is provided above the drying tube 3, and an exhaust hole is provided on the wall of the exhaust tube 6 60. One end of the exhaust pipe 6 is connected with a dust collector 61, and one side of the drying cylinder 3 is provided with an electric heating pipe 7, and the lower end of the electric heating pipe 7 is provided with a connecting pipe 70, and the connecting pipe 70 is connected to the drying cylinder At the bottom of 3, the connecting pipe 70 is provided with a thermometer 71, and a windmill 72 is connected above the electric heating tube 7. The air inlet 73 of the windmill 72 is connected to the air duct 43 of the magnetron 4, and the electric heating tube 7 A control box 74 is provided on the side of the device. The control circuit inside the control box 74 is an existing technology, and no detailed description is given here.
In use, as shown in Figure 4, first install a windmill 80 in the frame 2, connect the other end of the air guide tube 51 of the inlet tube 5 to the windmill 80, and connect the inlet tube 5 The feed pipe 50 is connected to the plastic tube 81, and the windmill 80 is additionally provided with an air guide tube 82, which is connected to the barrel 90 of the injection molding machine 9, and connects one end of the guide tube 33 of the storage barrel 31 to On the barrel 90 of the injection molding machine 9; put the undried plastic in the plastic barrel 80, start the windmill 80, attract the plastic from the plastic barrel 81 to the inlet barrel 5, and the plastic falls from the inlet barrel 5 to In the drying cylinder 3, at the same time, the electric heating switch and its windmill 72 are activated, the electric heating tube 7 starts to heat to the set temperature, and the windmill 72 starts to transfer the external cold air from the air inlet 42 of the air filter 41 through the magnetron 4 The connecting pipe 40 is attracted to the air guide pipe 43, and then discharged into the electric heating pipe 7 by the windmill 72. The air is heated in the electric heating pipe 7, and the hot air is discharged into the drying cylinder 3 by the connecting pipe 70, and will be placed in the drying cylinder 3. The plastic inside is blown up, forming a downward-to-up tumbling state. When the plastic is blown higher than the magnetron 4, the magnetron 4 starts to generate microwave heating. Using the microwave heating principle of the magnetron 4, Quickly evaporate the water molecules of the plastic, so that the plastic can be dried quickly, greatly saving drying time, and the drying effect is excellent. The moisture formed by microwave heating can be discharged by the exhaust hole 60 on the wall of the exhaust pipe 6 provided above the drying cylinder 3 to keep the inside of the drying cylinder 3 dry. In addition, the dust generated by the plastic during drying can be collected by the dust collector 61, so as to keep the air in the workshop clean, and the suction force of the windmill 72 sucks the external cold air from the air inlet 42 into the communicating pipe 40. The cold air can reduce the high temperature of the magnetron 4 due to heating, reduce the damage rate of the magnetron 4 due to long-term operation at high temperature, and can increase its service life, and passes through the magnetron 4 in the communicating tube 40 The air is guided by the air guide tube 43 to the windmill 72, and then heated and guided by the electric heating tube 7 to the drying cylinder 3 for use. The resources can be reused. The electromagnetic waves generated by the heating of the magnetron 4 pass through the drying cylinder 3 The barrier and the barrier of the box 20 outside the rack can reliably block electromagnetic waves in the box 20, and it is extremely safe to use. The above-mentioned dried plastic falls into the storage barrel 31 for storage. When the plastic in the barrel 90 of the injection molding machine 9 drops to a low position, the windmill 80 is started, and the dried plastic is removed from the storage barrel with the help of the guide tube 33 31 is guided to the barrel 90 of the injection molding machine 9 for injection molding by the injection molding machine 9. In this way, the method of drying the plastic by means of the microwave heating of the magnetron 4 does save time and power, and the drying effect is better than the general method of drying the plastic by heating with hot air.
In summary, the plastic dryer in the present invention can indeed achieve the intended purpose and effect, and is more ideal than traditional plastic dryers.
