A torsion spring (not shown) is provided between the push plate 16 and the transmission disc 12. A sliding seat 17 is arranged in the hydraulic passage 15. One side of the sliding seat 17 is connected with a stirring rod 18. The sliding seat 17 and the transmission disc 12 are internally connected with a first spring 19.
In addition, in designing the present device, it is necessary to make the pressure F ρ ghs of water larger than the spring force F Kx of the first spring 19 in a state where the water tank 11 is filled with water. Wherein x is the maximum displacement of the first spring 19, and s is the area of the sliding seat.
The related structures of the transmission disc 12 are at least two and are respectively arranged at two sides of the transmission seat 7.
Correspondingly, a communication water pipe 20 is connected between the water inlet channel 13 and the water injection tank 11, and the communication water pipe 20 enables water in the water injection tank 11 to enter the water inlet channel 13 along the communication water pipe 20, and simultaneously, a liquid level difference is formed, so that the pressure of the water in the water inlet channel 13 is improved.

Then, the pressing plate 10 moves upwards to ensure that the water outlet is not communicated with the water injection tank 11 any more, the water pump 26 continues injecting water, the transmission disc 12 moves downwards in the reverse direction to rotate, and the activated carbon is stirred and sewage is sprayed. Repeating the steps to ensure that the sewage is fully adsorbed and treated;
5. the sewage after the active carbon treatment enters the disinfection filter screen 5 through the active carbon filter screen 6, thereby disinfecting the sewage, finally filtering the sewage which is discharged through the water outlet pipe 2 at the rear part through the micro filter screen 4, and recycling the sewage.
Has the beneficial effects that:
1. according to the invention, the transmission seat 7 is rotated and moved by utilizing the hydraulic pressure of sewage during sewage treatment, and the stirring rod 18 is driven to penetrate through the transmission seat to stir the activated carbon, so that the stirring effect on the activated carbon and the rotating spraying effect of the sewage centrifugal force can be realized without an additional electric driving device in the whole process, the contact area of the sewage and the activated carbon is increased, compared with the activated carbon in a static state, the treatment mode prolongs the sewage treatment speed, but achieves a very good effect on the aspect of energy conservation and environmental protection, the distribution positions of the activated carbon in the filter frame 1 are changed, so that all the activated carbons can participate in the sewage treatment process, the utilization rate of the activated carbon is increased, and the sewage treatment effect is improved.
2. After the water outlet is arranged, the pressing plate 10 can move up and down, so that the stirring rod 18 rotates back and forth, and sewage is discharged in a rotating spraying mode while the activated carbon is fully stirred. In addition, the sewage flowing out of the water outlet can also fall onto the transmission disc 12 and fall into the activated carbon under the action of centrifugal force for treatment, so that the sewage treatment speed is further improved;
3. the floating block 21 is adopted to seal the water pipe 20, so that the stirring rod 18 is positioned inside the transmission disc 12 when the transmission disc 12 initially moves downwards, and the resistance of the transmission disc 12 entering the activated carbon is reduced.
