[0040] Working principle: sewage enters the interior of the barrel body 1 through the pipe on the left side of the barrel body 1, and after being filtered by the filter frame 4, it will fall into the bottom end of the barrel body 1. At this time, the heater 2 is started to heat the sewage in the barrel body 1. After the sewage is heated, the evaporated water vapor will be discharged through the pipe on the right side of the barrel body 1. During this period, the motor 6 is started to drive the driving sleeve 7, and the driving sleeve 7 drives the rotating column 8 to rotate. The rotating column 8 will be driven to drive the stirring piece 13 to rotate through the connecting seat 14, thereby driving the stirring piece 13. The stirring piece 13 will stir the sewage in the barrel body 1 and accelerate the evaporation efficiency of the sewage. When the stirring piece 13 rotates, the pushing spring 10 pushes the sliding sleeve 11, thereby driving the pushing piece 12, and the pushing piece 12 pushes the stirring piece 13 to fit tightly with the inner wall of the barrel body 1, thereby cleaning the inner wall of the barrel body 1. While the stirring piece 13 stirs the sewage in the barrel body 1, the pushing spring 10 pushes the sliding sleeve 11, thereby pushing the pushing piece 12. The pushing piece 12 will push the stirring piece 13 and the inner wall of the barrel body 1 to scrape and clean, avoiding dirt accumulation affecting heat transfer, reducing heat waste, and improving evaporation efficiency. When it is necessary to clean the garbage filtered in the filter frame 4, manually rotate the driving column 20 and the rotating piece 21 to drive the pushing block 22 so that the pushing block 22 no longer squeezes the roller 18, thereby separating the card plate 17 from the card slot 15. At this time, the barrel cover 5 can be opened to clean the dirt accumulated on the filter frame 4. By driving the pushing block 22, the pushing block 22 pushes and leaves the roller 18, driving the card plate 17 to engage and separate with the card slot 15, thereby quickly cleaning the filter frame 4, shortening the cleaning process, and improving the efficiency of cleaning the filter frame 4.
