[0021] Working principle: When in use, the external water pump injects water into the cleaning cylinder 11 through the water injection pipe 17, and injects raw material particles into the cleaning cylinder 11 through the feed pipe 14. The first motor 133 drives the first screw 135 to rotate counterclockwise through the first transmission shaft 134. When the first screw 135 rotates, it drives the water inside the cleaning cylinder 11 to rotate and stir the raw materials. The raw materials are cleaned inside the cleaning cylinder 11 to remove dust on the surface of the raw materials. Then, the first solenoid valve 151 is opened, and the water inside the cleaning cylinder 11 flows out from the first water outlet pipe 15. The small particles pass through the first filter plate 16 and flow into the recovery device from the first water outlet pipe 15. Then, the first motor 133 drives the first screw 135 to rotate clockwise through the first transmission shaft 134. The particles are transported to the upper end of the first transport cylinder 13 by the first screw 135. The third motor 27 drives the third rotating shaft 271 to rotate through the third rotating shaft 271. The particles at the upper end of the first transport cylinder 13 enter the interior of the drying cylinder 21. The second screw 272 transports the particles to move inside the drying cylinder 21. When the particles pass through the filter plate 22, the second motor 25 3 drives the fan blades 254 to rotate, so that the outside air passes through the second filter plate 251 into the hot air frame 25, and flows toward the inside of the drying cylinder 21. When the air flows, it is heated by the heating plate 255, and the hot air passes through the water filter plate 22 into the drying cylinder 21, heats the raw materials, removes the moisture on the surface of the raw materials, and the moisture evaporates into water vapor. The water vapor follows the air through the water filter plate 22 at the lower end into the water accumulation frame 23, and enters the cleaning cylinder 11 along the second water outlet pipe 24. The water vapor is liquefied inside the cleaning cylinder 11, thereby Most of the moisture is recovered and the raw materials are dried. The materials fall from the first discharge pipe 28 into the collecting frame 31. The fourth motor 34 drives the fixed cylinder 342 to rotate through the fourth rotating shaft 341. The fixed cylinder 342 drives the stirring arm 343 to rotate, and the particles in the collecting frame 31 are stirred, so that the particles can evenly enter the second discharge pipe 35, and then enter the melting equipment through the second discharge pipe 35. After being buffered by the collecting frame 31, the materials can continuously enter the melting equipment, thereby ensuring the stability of feeding.
