The first chamber 101 conducts drying treatment on the waste, the second chamber 102 conducts pyrolysis reaction on the dried waste, the third chamber 103 conducts gasification reaction on the waste after the pyrolysis reaction, and the arrangement from high to low can reduce the use of the transmission device and lower the device cost. During the operation and treatment process of the first chamber 101, the second chamber 102, and the third chamber 103, the top cover 105 seals the upper end of the first chamber 101, and at the same time, the top cover 105 supports and fixes the first driving motor 106. During the waste treatment process, the first driving motor 106 is started to operate, thereby driving the first shaft seat 107 to rotate. At the same time, due to the linkage of the first shaft seat 107, the second shaft seat 108, the third shaft seat 109, the fourth shaft seat 110, the first shaft rod 111, the second shaft rod 112, and the third shaft rod 113, each auger blade 114 rotates.

During the closing process, the telescopic electric cylinder 118 contracts to drive the closing plate 119 to move outward until the closing plate 119 contacts the inner side of the cavity 115 to achieve the closing effect. During the blanking process, the telescopic electric cylinder 118 extends to drive the closing plate 119 to move inward, so that the closing plate 119 is embedded inside the cavity seat 116.

The cavity seat 116 is embedded into the interior of the cavity 115, and the cavity 115 supports the cavity seat 116. The support frame installs and supports the telescopic electric cylinder 118, and at the same time, the telescopic electric cylinder 118 drives the movement of the closing plate 119. During the closing process, the telescopic electric cylinder 118 contracts to drive the closing plate 119 to move outward until the closing plate 119 contacts the inner side of the cavity 115 to achieve the closing effect. During the feeding process, the telescopic electric cylinder 118 extends to drive the closing plate 119 to move inward, so that the closing plate 119 is embedded into the interior of the cavity seat 116. At the same time, a feeding port is opened between the cavity seat 116 and the cavity 115. Driven by the screw blade 114, the processed waste is fed through the feeding port. The cavity seat 116 is embedded into the interior of the cavity 115, and the cavity 115 supports the cavity seat 116. The support frame installs and supports the telescopic electric cylinder 118, and at the same time, the telescopic electric cylinder 118 drives the movement of the closing plate 119. During the closing process, the telescopic electric cylinder 118 contracts to drive the closing plate 119 to move outward until the closing plate 119 contacts the inner side of the cavity 115 to achieve the closing effect. During the feeding process, the telescopic electric cylinder 118 extends to drive the closing plate 119 to move inward, so that the closing plate 119 is embedded into the interior of the cavity seat 116.Meanwhile, a discharge opening is opened between the cavity base 116 and the cavity 115, and the processed waste is discharged through the discharge opening driven by the auger blade 114. When starting for the first time, untreated waste is added to the first chamber 101 for drying treatment. After the drying treatment is completed, the waste enters the second chamber 102 for pyrolysis treatment. The first chamber 101 is closed and untreated waste is added again for drying treatment. When the treatment of the first chamber 101 and the second chamber 102 is completed, first open the second chamber 102 to discharge the waste after pyrolysis treatment into the third chamber 103, and at the same time close the second chamber 102. Then discharge the waste after drying treatment in the first chamber 101 into the second chamber 102, and then close the first chamber 101 again. Add untreated waste to the first chamber 101 again. When the treatment of the first chamber 101, the second chamber 102 and the third chamber 103 is completed, first discharge the waste in the third chamber 103, then discharge the waste in the second chamber 102 into the third chamber 103, and then discharge the waste in the first chamber 101 into the second chamber 102.
