Technical Field

The application relates to the field of rainwater collection, in particular to a house rainwater recovery device.

Background

With the rapid development of economy and the acceleration of urbanization process, the problem of shortage of fresh water resources is more prominent. The rainwater recycling can save a large amount of water cost for users, reduce the urban rain and flood damage and relieve the situation of urban water resource shortage, has good economic benefit, social benefit and environmental benefit, and is an important means for sustainable utilization of water resources. The quality of the rainwater is obviously better than the quality of the water which is recovered generally, and the rainwater can be directly applied to the aspects of flower and plant irrigation, landscape water, road cleaning and the like. When the rainwater in a roof, a hardened ground, a lawn and other rainwater collecting media can be collected, the initial rainwater can contain impurities, such as bird droppings, paper scraps, leaves, oil stains and other easily-polluted substances.

Chinese patent publication No. CN209412942U discloses a house rainwater recovery device, which comprises a siphon drainage system arranged on a roof and a sewer pipe connected with the siphon drainage system, wherein the sewer pipe is connected with a settling tank, a spray component capable of spraying a flocculating agent is arranged above the settling tank, a stirring device for stirring sewage in the settling tank is arranged on the side wall of the settling tank, one side of the settling tank far away from the sewer pipe is connected with a water outlet pipe, the water outlet pipe is connected with a safety filter, the safety filter is connected with a disinfection device, the other end of the disinfection device is connected with a water return pipe, the water return pipe extends into the house, and the water return pipe is connected with a water return pump.

When raining, the rainwater enters into the downcomer through hydrocone type drainage system, rainwater in the downcomer enters into the sedimentation tank through gravity, and back spray subassembly sprays the flocculating agent towards in the sedimentation tank, suspended particles and floater in the rainwater sink into the bottom of sedimentation tank, at the in-process that the spraying subassembly sprayed the flocculating agent, agitating unit work stirs the rainwater, in order to accelerate the sedimentation rate of sedimentation tank, after the rainwater subsides in the sedimentation tank and accomplishes, the return water pump work, the rainwater that will subside and accomplish enters into the wet return, then the rainwater enters into and carries out the precision filtration in the security type filter, rethread degassing unit filters the rainwater, carry the user with the rainwater at last.

In view of the above-mentioned related art, the inventor believes that, since the rainwater is not primarily filtered, so that the amount of impurities flowing into the settling basin is large, the filtering strength of the cartridge filter is increased, and the filtering effect of the cartridge filter can be ensured only by frequently cleaning the filter element in the cartridge filter.
