Description

Building rainwater recycling filter reuse device

Technical field

The utility model relates to a water-saving and environment-friendly device, in particular capable of storing and utilizing rainwater.

Background technique

At present, the known building rainwater is discharged to the street through the building rainwater drain pipe, and then drained through the municipal drainage pipe network, which wastes water resources, and even if secondary treatment is performed, the cost is increased.

Contents of the invention

In order to overcome the problem that the prior art cannot collect and utilize rainwater, the utility model provides a rainwater recovery and reuse device for buildings. The device can not only collect rainwater, but also reduce urban water accumulation in rainy seasons.

The technical scheme adopted by the utility model to solve the technical problem is: the water inlet of the water tank is connected with the rainwater discharge pipe of the building, the water outlet pipe of the water tank is connected with the water use ground, the sedimentation sewage pipe is arranged at the lower part of the water pipe, and the water level control pipe of the water tank is arranged according to the water level.

When there is rainfall, the rainwater flows into the water tank through the building drain pipe under the action of the water level difference. When the collected rainwater exceeds the water level control nozzle, the excess rainwater is discharged to the street through the water level control pipe. Filtration process: Under the action of gravity, the impurity sediment in the rainwater in the water tank enters the sedimentation sewage pipe through the main joint door and the water pipe, and the cleaner rainwater flows into the water use through the water pipe branch, and the dirt can be drained after the rainwater in the water tank Or regularly open the outlet of the sediment drain pipe to remove the sediment when the main joint door is closed.

The beneficial effect of the utility model is that it can collect and utilize rainwater, which is natural reclaimed water, can reduce urban water accumulation in rainy seasons, provide emergency water sources, and has a simple structure and easy maintenance.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a structural diagram of the utility model.

Fig. 2 is a structural diagram of the first embodiment of the rainwater recovery and reuse device for buildings.

Fig. 3 and Fig. 4 are the structural diagram of the second embodiment of the rainwater recovery and reuse device for buildings.

Among the figure 1. water tank, 2. building rainwater discharge pipe, 3. water level control pipe, 4. general joint door, 5. water pipe, 6. sedimentation sewage pipe.

Detailed ways

In Fig. 1, the water tank (1) is arranged in the spare space above the top floor stairwell in the building, the building drainpipe, (2) is connected with the water tank (1) through the wall, and the water level control pipe (3) controls the water level and leads to On the outdoor ground, the water pipe (5) is connected to the bottom of the water tank through the general joint door (4), and the sediment discharge pipe (6) is installed at the lower end of the water pipe, so that the high water level drop of the water tank can be used to directly supply water to the branch users of the water pipe.

In the embodiment shown in Fig. 2, a large water tank (1) is supplied with rainwater by a plurality of building drain pipes (2), and the water tank (1) is provided with both inside and outside the building, and the water tank is arranged as high as possible within the allowable range, both To ensure that the drain pipe (2) utilizes the drop to supply the rainwater to the water tank (1), and also take into account the water level drop in the water tank for the user, the water level control pipe (3) can be arranged in the water tank, or can be installed on the side of the water tank (1), and Multiple root arrangements are possible.

In another embodiment shown in Fig. 3 and Fig. 4, a plate or a gutter can be installed on a building without a rainwater drainpipe, and a water tank can be connected to collect rainwater, and other structures are the same as above.

Claims (5)
