s3, when the first rotating shaft (406) rotates forwards and backwards, the first movable sleeve rod (407) and the second movable sleeve rod (408) are driven to move back and forth on the first rotating shaft (406), and because the rotating directions of the second thread and the third thread are opposite, the first movable sleeve rod (407) and the second movable sleeve rod (408) rotate in opposite directions, and then the first stirring rod (409) on the first movable sleeve rod (407) and the second movable sleeve rod (408) are driven to rotate in different directions;

s4, the stirring box (401) moves downwards by starting the electric telescopic push rod (6), so that the disinfection liquid disinfects the solid waste in the stirring box (401), and the disinfection lamps (8) on the two sides ensure that the disinfection effect is better;

s5, disinfectant is added into the operation box (1), the first liquid box (501) and the second liquid box (502), a second motor (504) is started to drive a second rotating shaft (505) to rotate, the rotation of the second rotating shaft (505) drives a spiral blade (506) to rotate, the second rotating shaft (505) and the spiral blade (506) drive liquid to rapidly rotate to form a vortex in the middle of the second liquid box (502), according to Bernoulli' S law, the higher the flow rate of the fluid, the lower the relative pressure, the vortex is the fluid with higher flow rate, the lower the surrounding pressure, so that the liquid on the vortex side can be sucked, the liquid in the operation box (1) is sucked into the first liquid box (501) through a liquid inlet pipe (503), the liquid in the first liquid box (501) is sucked into the second liquid box (502) through a circulating liquid pipe (508), and the liquid is conveyed to a separation plate (509) through the circulating liquid pipe (508), the liquid is impacted, so that the medicine powder in the liquid is better mixed, and the disinfectant is brought into the first liquid tank (501) through the liquid outlet pipe (507), thereby forming a liquid circulation ring.
