Unpowered rainwater split-flow sewage intercepting device
The invention provides an unpowered rainwater split-flow sewage intercepting device. The device comprises a split-flow chamber, a water inlet pipe is arranged on the side, close to the top, of the split-flow chamber, the water inlet pipe conveys rainwater downward to a hopper-shaped coarse filtration device through a centrifuge device, the edge of a large upper port of the hopper-shaped coarse filtration device is attached to the inner wall of the split-flow chamber closely, a small lower port of the hopper-shaped coarse filtration device is provided with a connecting pipe, the connecting pipe is provided with a water outlet pipe with a fine filtration device, a floating ball device is arranged under the connecting pipe, when water volume reaches a certain degree, a floating ball of the floating ball device blocks the bottom of the connecting pipe, a gap is formed between the floating ball device and the side wall of the split-flow chamber, a water flow reduction device is arranged at the bottom of the split-flow chamber, and the aperture of the water flow reduction device is larger than that of the hopper-shaped coarse filtration device. The device has a dual effects of split-flow and filtration; the rainwater flow is utilized to conduct automatic adjustment, power is not needed, the reliability is high, and maintenance is not needed; two layers of filter screens are adopted, a hopper-shaped filter screen blocks impurities with large particle sizes, and an outlet filter screen further conducts fine filtration; the split-flow chamber can be emptied automatically, and the occupied area is small.
