[0025] The working principle of this utility model:
[0026] First, wastewater is injected into the mixing tank 2 through the inlet 9. Then, the motor 67 is controlled to operate, causing the motor 67 to drive the drive rod 68, which is fixedly connected to its output shaft, to rotate. When the drive rod 68 rotates, it drives the drive gear 717, which is fixedly connected to it, to rotate. This causes the drive gear 717 to drive the driven gear 716, which meshes with it, to rotate. When the driven gear 716 rotates, it drives the transmission rod 713, which is fixedly connected to it, to rotate. This causes the transmission rod 713 to drive the drive wheel 712, which is fixedly connected to it, to rotate. When the drive wheel 712 rotates, it drives... The driven wheel 710 is driven to rotate by the belt 711, which in turn drives the rotating shaft 78 fixedly connected to it to rotate. When the rotating shaft 78 rotates, it drives the fan blade 79 fixedly connected to it to rotate, which causes the fan blade 79 to input high-speed gas into the venturi tube 74. At this time, the narrower part in the middle of the venturi tube 74 forms a negative pressure, which causes the feed pipe 73 to draw the liquid and drug mixture in the inner cavity of the box 71 into the venturi tube 74. After the gas input by the fan blade 79 vigorously mixes the liquid and drug mixture, it is injected into the inner cavity of the mixing tank 2.
[0027] Simultaneously, when the drive rod 68 rotates, it drives the gear 610, which is fixedly connected to it, to rotate. This causes the gear 610 to drive the full-tooth gear ring 611, which meshes with it, to rotate. The full-tooth gear ring 611, in turn, drives the rotating ring 612, which is fixedly connected to it, to rotate. The rotating ring 612, in turn, drives the residual-tooth gear ring 613, which is fixedly connected to it, to rotate. The residual-tooth gear ring 613, in turn, drives the gear 66, which meshes with it, to rotate. This causes the gear 66 to drive the rotating rod 64, which is fixedly connected to it, to rotate. When rotating, it will drive the cam 65, which is fixedly connected to it, to rotate, thereby causing the cam 65 to push the movable plate 5 downward. At this time, the movable plate 5 will drive the stirring device 8 to flip under the action of the ball joint 3 and the connecting seat 4, thereby avoiding the formation of a stirring dead zone. When the residual tooth ring 613 disengages from the gear 66, the coil spring 63 will drive the rotating rod 64 to reverse due to the elastic force, thereby moving the cam 65 to the initial position for the next use. After the sewage treatment in the inner cavity of the stirring tank 2 is completed, the water in the inner cavity of the stirring tank 2 is discharged through the outlet 10.
