Description

Technical Field

[0001] The utility model relates to the technical field of rainwater recycling, in particular to a building rainwater filtering and recycling device. Background Art

[0002] Rainwater is an important freshwater resource. The recycling and reuse of rainwater can effectively save water resources. At present, recycling rainwater on building roofs is a common rainwater recycling measure. However, since rainwater will adhere to dust in the air, when it falls on the roof of a building, it will carry mud and sand and flow down. Therefore, a filtering and recycling device is needed to recycle rainwater.

[0003] The Chinese patent number CN212731345U discloses a rainwater recycling filter device for underground buildings, including a frame, a purification mechanism is installed on the surface of the frame, and the interior of the purification mechanism includes a water inlet, and the water inlet is opened on the surface of the frame. In the utility model, under the action of the purification mechanism, rainwater flows into the conduit through the water inlet, passes through the primary filter layer, filters the rainwater, and then flows to the inside of the frame through the water outlet, and is filtered and discharged through the third filter layer inside the second diversion port for recycling. When the water level inside the conduit is located at the pressure relief port, the rainwater flows to the inside of the frame through the pressure relief port, and then is filtered and discharged through the second diversion port. When the water level inside the frame is located at the first diversion port, the rainwater is filtered and discharged through the second filter layer inside the first diversion port for recycling, effectively avoiding the situation that the rainwater is not smooth due to the small gap in the filter layer, and even causes the rainwater to flow back, thereby improving the filtering efficiency of the rainwater.

[0004] Although the above-mentioned device can filter and recycle rainwater, the filter material is prone to clogging after long-term use, the rainwater flow is not smooth, and the filtering performance will decrease. However, the filter layer used is located inside the device, which is inconvenient to remove and replace. In addition, the height of the rainwater recovery pipe is fixed, which is inconvenient to adjust according to the height of the building drainage point. Therefore, improvement is urgently needed.
