After smelting for a period of time, the first solenoid valve 12 is opened to allow the copper liquid to enter the screening box 20. The copper liquid will pass through the filter screen 25 and fall to the bottom of the screening box 20, while the unmelted debris will remain on the filter screen 25. The second motor 31 will operate regularly, so that the ball screw 32 rotates, and the scraper 34 at the bottom of the movable plate 33 sweeps the debris on the filter screen 25, so that the debris enters the return pipe 41 from the guide pipe 23. After that, the movable plate 33 is reset, and the first motor 44 is operated to allow the debris to enter the smelting cylinder 10 again through the conveying pipe 42 through the conveying auger 43 for smelting until the debris is completely smelted and passes through the filter screen 25. Finally, the second solenoid valve 24 is opened to discharge the smelted copper liquid for subsequent air conditioning and refrigeration copper pipe processing.
