(2) And (3) operation of the stirring mechanism: firstly, the transmission device 3011 is started, a transmission shaft of the transmission device 3011 drives the cam 3012 to rotate, when a protruding end of the cam 3012 contacts with one force-bearing body 309, one force-bearing body 309 is pushed to move in a direction away from the transmission device 3011, and through the arrangement that two connecting rods a308 are connected with each other, the other force-bearing body 309 is pulled to move in a direction close to the transmission device 3011, so that the connecting rod a308 drives the piston a307 to slide in the output body a306, wherein the piston a307 sliding in a direction away from the transmission device 3011 pumps hydraulic oil in the hydraulic cylinder 301 on one side into the output body a306, and the piston a307 sliding in a direction close to the transmission device 3011 presses hydraulic oil in the output body a306 on the other side into the hydraulic cylinder 301, thereby realizing staggered extension and retraction of the two hydraulic cylinders.

(3) Operation a of the aeration mechanism 4: after oxygen in the air in the water tank 201 with the filling belt is absorbed by the desulfurization wastewater, redundant air is accumulated above the water tank 201, and after certain air concentration is reached, the air pressure pushes the hole plugging body 404 to be unfolded out of the air hole 7 and then to be discharged.

(4) Operation B of the aeration mechanism 4: when the connecting rod A308 reciprocates, the connecting rod B407 is driven to reciprocate together, then the connecting rod B407 drives the piston B406 to reciprocate in the output body B405, when the piston B406 slides in a direction close to the transmission device 3011, negative pressure is generated in the output body B405, the negative pressure pulls the piston C4013 in the movable cylinder 4012 to slide downwards through the closed air guide body 408, after the piston C4013 slides downwards, the left movable plate 4011 is separated from the joint with the connecting rod C4014 and is unfolded through the pulling of the connecting software 4015, so that the output body B405 sucks air from the outside through the left side of the air guide body 408, when the piston B406 slides in a direction away from the transmission device 3011, the piston B406 fills the air in the output body B405 into the air guide body 408 and pushes the piston C4013 to slide upwards, the piston C4013 drives the connecting rod C4014 to slide upwards and pulls the right movable plate 4011 to unfold, so that the air is filled into the water tank 201 through the air guide body 408, when the protruding end of the cam 3012 is separated from the, the link B407 stops sliding, the telescopic body B4016 rebounds to drive the link C4014 to return to the initial position, and the movable plate 4011 is closed.

(5) Stirring of the desulfurization wastewater B: when desulfurization waste water stirs in water tank 201, prevent that the 205 atress of precipitate promotes sliding body 204 and slides in spout A5 for prevent that precipitate 205 stirs desulfurization waste water through sliding, and prevent that precipitate 205 side receives desulfurization waste water and strike the back, can get up the suspended solid separation, then receive desulfurization waste water at the opposite side and strike the back, utilize the sieve mesh to enlarge rivers pressure.
