Rainwater purification device for roof garden

Abstract

The invention discloses a rainwater purification device for a rooftop garden. The rainwater purification device comprises a base, wherein a purification tank is arranged on one side of the top of thebase; a reservoir is arranged on one side of the purification tank and is internally provided with a quartz sand layer; an activated carbon layer is arranged at the bottom of the quartz sand layer; astirring roller is arranged at the bottom of the activated carbon layer; the surface of the stirring roller is provided with stirring blades; a bearing is connected to one end of the stirring roller and a stirring motor is connected to the other end of the stirring roller; a motor support is arranged at the bottom of the stirring motor; the top of the reservoir is provided with an water inlet andone side of the bottom of the purification tank is provided with a water outlet. According to the rainwater purification device disclosed by the invention, by arranging the stirring roller and puttingpurifying agents such as alum from the water inlet, rainwater is fully mixed with the alum, and further the mixing efficiency is improved; the reservoir is used for storing purified rainwater, so that greater convenience in use is realized.

Description

technical field [0001] The invention relates to the technical field of rainwater purification equipment, in particular to a rainwater purification device for roof gardens. Background technique [0002] In rainy weather, a lot of rainwater will fall to the ground, and it may seep below the surface to form a storage of surface water, or it will flow into lakes and seas, and fall again with the next precipitation, forming a cycle that repeats itself. Some will collect the rainwater that falls naturally for irrigation to save resources at home, but the existing collected rainwater has more impurities, which is not conducive to use. [0003] Therefore, it is necessary to invent a kind of roof garden rainwater purification device to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a rainwater purification device for roof gardens to solve the problems raised in the above-mentioned background technology. [0005] In o...
