[0026] In one embodiment, the top of the bracket 4 is provided with a hydraulic oil storage pot 10, and the two sides of the hydraulic oil storage pot 10 are respectively provided with a first pneumatic booster pump 3 and a second pneumatic booster pump 26. The top of the second pneumatic booster pump 26 is provided with an upper pressure chamber action hydraulic electromagnetic valve 5. The oil outlet of the first pneumatic booster pump 3 is communicated with a connecting oil delivery pipe 8. The connecting oil delivery pipe 8 is communicated with the oil inlet of the second pneumatic booster pump 26. The oil outlet of the second pneumatic booster pump 26 is communicated with an upper pressure chamber down pressure oil delivery pipe 6. The outer side wall of the upper pressure chamber down pressure oil delivery pipe 6 is provided with a down pressure cylinder pressure sensor 12. The oil inlets of twelve upper pressure chamber down pressure oil cylinders 14 and four upper pressure chamber lifting oil cylinders 15 are respectively provided with a pressure chamber oil cylinder distributor 16. The output end of the pressure chamber oil cylinder distributor 16 is communicated with a hydraulic oil pipe 17. The oil inlet of the second pneumatic booster pump 26 is communicated with a second upper pressure chamber lifting oil delivery pipe 9. The outer side wall of the second upper pressure chamber lifting oil delivery pipe 9 is communicated with a first upper pressure chamber lifting oil delivery pipe 7. The outer side walls of the first upper pressure chamber lifting oil delivery pipe 7 and the second upper pressure chamber lifting oil delivery pipe 9 are respectively communicated with corresponding pressure chamber oil cylinder distributors 16 of the four upper pressure chamber lifting oil cylinders 15. The twelve upper pressure chamber down pressure oil cylinders 14 and the four upper pressure chamber lifting oil cylinders 15 are respectively communicated with the corresponding pressure chamber oil cylinder distributors 16 to realize synchronous movement.

[0027] In one embodiment, the top of the upper pressure chamber 1 is communicated with a sewage inlet pipe 13. The outer side of the sewage inlet pipe 13 is provided with a pressure chamber pressure sensor 11. The inner side of the sewage inlet pipe 13 is provided with a check valve. The bottom of the upper pressure chamber 1 is provided with a sealing ring 27. The pressure in the upper pressure chamber 1 is detected by the pressure chamber pressure sensor 11 to determine whether the dust and dirt filtered by the filter paper is saturated. The inner side of the sewage inlet pipe 13 is provided with a check valve to prevent sewage from being discharged from the sewage inlet pipe 13.

[0028] In one embodiment, the bottom of the lower pressure chamber 2 is communicated with a sewage discharge pipe 24. The filtered sewage is discharged through the sewage discharge pipe 24.

[0029] In one embodiment, the upper surface of the lower pressure chamber 2 is provided with a filter material bracket 18. When the high-pressure sewage in the upper pressure chamber 1 enters the front of the filter paper to support the strong pressure, the filter paper is prevented from being damaged by the filter material bracket 18.

[0031] In operation, this invention works as follows: The first pneumatic booster pump 3 and the second pneumatic booster pump 26 draw hydraulic oil from the upper pressure chamber lifting cylinder 15 through the first upper pressure chamber lifting oil supply pipe 7 and the second upper pressure chamber lifting oil supply pipe 9, causing the upper pressure chamber lifting cylinder 15 to lift the upper pressure chamber 1. Then, the winding motor 23 drives the filter material winding roller 22 to rotate, moving the filter material on the filter material unwinding roller 20, so that the filter material moves between the upper pressure chamber 1 and the lower pressure chamber 2. Then, the first pneumatic booster pump 3 and the second pneumatic booster pump 26 draw hydraulic oil from the hydraulic oil reservoir 10, which is then discharged into the hydraulic oil pipe 17 through the upper pressure chamber lower pressure oil supply pipe 6, and then into the pressure chamber cylinder distributor 16. The pressure chamber cylinder distributor 16 synchronizes the twelve upper pressure chamber lower pressure cylinders 14, causing the upper pressure chamber to lift. The pressure chamber lowering cylinder 14 drives the upper pressure chamber 1 to press down, pressing the filter media. The sealing ring 27 on the upper pressure chamber 1 improves the sealing between it and the lower pressure chamber 2. Then, the sewage enters between the upper pressure chamber 1 and the lower pressure chamber 2 through the sewage inlet pipe 13 and is filtered by the filter media. After filtration, it is discharged through the sewage outlet pipe 24. The pressure in the upper pressure chamber 1 is detected to determine whether the filter paper is saturated with the dust and dirt filtered out. If the pressure reaches the detection value, it means that the filter paper is saturated and needs to be replaced. The upper pressure chamber lifting cylinder 15 drives the upper pressure chamber 1 to lift up. Then, the winding motor 23 drives the filter media winding roller 22 to rotate, which moves the filter media on the filter media unwinding roller 20, so that the filter media moves between the upper pressure chamber 1 and the lower pressure chamber 2. The upper pressure chamber lowering cylinder 14 drives the upper pressure chamber 1 to press down. This process is repeated to achieve automated filtration of sewage.
