The auger conveying rod 5 rotates to stir the raw materials in the heating chamber 3, and at the same time, the raw materials in the heating chamber 3 are conveyed by the rotation of the auger conveying rod 5. The raw materials conveyed by the auger conveying rod 5 enter the inner side of the guide pipe 8 from the heating chamber 3. After the raw materials enter the inner side of the guide pipe 8, the auger conveying rod 5 continuously squeezes the raw materials entering the inner side of the guide pipe 8, so that the raw materials that meet the standards are filtered by the filter screen 11 and then enter the discharge port 9 and are sprayed on the surface of the workpiece, while the impurities that do not meet the standards are intercepted by the filter screen 11 on the inner side of the guide pipe 8.
