[0035] How it works

[0036] Before activating the rainwater interception and sewage return system for rainwater interception and sewage return treatment, the system should be inspected. Check whether the safety measures are in place, ensure that the connections between the various components are intact and effective, ensure the sealing and airtightness of the system, and ensure that the system can operate normally.

[0037] Before activating the rainwater sewage interception and return system for rainwater sewage interception and return treatment, the garbage collection frame 25 is placed in the garbage collection trough 27. At this time, the garbage collection frame 25 presses the sealing pressure piston 40 to press the hydraulic oil in the hydraulic groove 41 into the sealing slide groove 39. The hydraulic oil entering the sealing slide groove 39 pushes the sealing piston 38 to move upward. During the upward movement of the sealing piston 38, it drives the pressure door 37 to open the sewage outlet 23.

[0038] At this time, the isolation plate 24 is in a vertical downward position, the sliding sleeve 36 is located above the vibrating member 34 in the sliding groove 32 , the scraper 35 is located on the upper side of the filter plate 14 , and the sedimentation tank 17 is located at the uppermost side of the sealing sliding groove 15 .

[0039] When rainwater mixed with silt and other garbage enters the rainwater sewage interception and return system, the water flows into the first shell 10 from the water inlet 11, and first falls on the filter plate 12. Larger solid waste falls on the filter plate 12 and is retained on the filter plate 12, while fine silt is carried down by the water flow into the sedimentation tank 17.

[0040] When a large amount of solid waste falls on the filter plate 12, the filter plate 12 drives the sliding sleeve 36 to move downward along the sleeve rod 33. During the downward movement of the sliding sleeve 36, the vibration member 34 is continuously pushed to swing, driving the sliding sleeve 36 and the filter plate 12 to vibrate slightly, so that the solid waste on the filter plate 12 falls into the sewage outlet 23 along the ramp. The solid waste entering the sewage outlet 23 pushes the isolation plate 24 to deflect along the torsion spring assembly 42, so that the solid waste falls into the garbage collection frame 25.

[0041] The solid waste entering the garbage collection frame 25 contains a small amount of water, which falls into the filter pool 21 through the water filter hole 22 at the bottom of the garbage collection frame 25. The water falling into the filter pool 21 falls into the sewage pipe 18 through the downpipe 20 and the one-way valve 19.

[0042] At the same time, some toxic and harmful gases may be generated in the solid waste entering the garbage collection frame 25. The generated gases enter the activated carbon filter chamber 30 through the air inlet 29, and are discharged to the outside through the exhaust port 28 after being adsorbed and filtered by the high-efficiency activated carbon in the activated carbon filter chamber 30.

[0043] The water entering the sedimentation tank 17 first falls on the sedimentation plate 16, and the silt settles on the sedimentation plate 16. The water passes through the filter plate 14 and enters the return pipe 13 and is discharged outward through the return pipe 85. Some pollutants floating on the water surface are adsorbed on the filter plate 14 and are scraped into the water by the scraper 35 driven by the sliding sleeve 36 when it moves downward.

[0044] As the sedimentation plate 16 continues to accumulate, the sedimentation plate 16 is continuously pressed downward, and finally the sedimentation plate 16 deflects downward along the rotating assembly 44 near the sewage pipe 18, and the sedimentation plate 16 and the polluted water are flushed into the sewage pipe 84 through the sewage pipe 18 and discharged.

[0045] After a period of use or when no water flows into the system, the garbage in the garbage collection frame 25 is cleaned out in time, and damaged parts or parts with poor functional effects are replaced.

Any equivalent structure or equivalent process transformation made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
