Finally, the raw materials will be hot-melted into molten iron by high temperature in the kiln body 3 and flow out through the discharge hole of the kiln body 3 at the lower part of the left support frame 2. The molten iron will pass through the first filter screen 20 and enter the cooling mold 19. The substances that are not easy to melt in the molten iron will be filtered out by the first filter screen 20. In this way, the hot melting of the raw materials is completed, and the subsequent processing can be carried out after cooling and solidifying in the cooling mold 19. The exhaust gas produced when the raw materials are hot-melted will be discharged by the exhaust fan 21 and enter the exhaust pipe 22. The exhaust gas entering the exhaust pipe 22 will be filtered through the second filter screen 23 and then discharged into the air. At this time, the hot melting of the raw materials is completed, and the power of the device is turned off after the work is completed.
