Detailed Description

The utility model will be described in detail below with reference to the following figures: as shown in fig. 1-3, a rainwater collecting and purifying device, the device 1 includes a plurality of collectors 2, the collectors 2 are connected to a water tank 4 through a pipeline 3, the rear of the water tank 4 is connected with an anaerobic zone 5, an aerobic zone 6 and a nanofiltration zone 7 through pipelines in sequence, and is finally connected to a reservoir 8 for storage, an aeration pipe 9 is arranged in the aerobic zone 6, a multi-layer nanofiltration membrane 11 with a membrane frame 10 is arranged in the nanofiltration zone 7, the top diameter of the collectors 2 is larger than the bottom diameter to form a water receiving port with an inverted trapezoid cross section, one end of the top of the collectors 2 is fixed, the other end of the collectors 2 is provided with a foldable cover plate 12, a foldable grid plate 13 is arranged below the cover plate 12 for blocking large leaves, a plurality of grid frames 15 arranged from top to bottom and provided with filter screens 14 are arranged in the collectors 2, the mesh sizes of the filter screens 14 on the grid frames 15 gradually decrease from top to bottom, two sides of the grid frame 15 are respectively fixed in clamping holes 22 on the inner side wall of the collector 2, the filter screen 14 is detachably mounted on the grid frame 15 in a rivet 16 mode, and if the filter screen 14 is replaced, the rivet 16 is detached and the filter screen 14 is replaced.

Two sides of the grid frame 15 are respectively placed on a stepped inner ledge 23 arranged on the inner side wall of the collector 2, the filter screen 14 is fixedly arranged on the grid frame 15, and the grid frame 15 can be taken out and integrally replaced if the filter screen 14 is replaced.

Aeration pipe 9 is last to be equipped with the aeration branch pipe 17 of arranging with aeration pipe 9 looks vertically to be equipped with aeration head 18 on aeration branch pipe 17, aeration pipe 9's air feed is by the oxygen machine 19 air feed of one side, the outside of water tank 4 is equipped with a direct pipeline 20 of irrigating and toilet flushing direct use, can use the rainwater not through filtering, domestic pipeline 21 is connected at 8 backs of cistern, can be used to domestic water.

The rainwater collecting device is simple in structure, collected rainwater is stored in the water tank, when only irrigation or toilet flushing and other water is needed, the rainwater is directly used through the straight-through pipeline on the outer side of the water tank, when the requirement on water quality is high, the collected rainwater is treated through the anaerobic zone, the aerobic zone and the nanofiltration zone through the water tank, and then domestic water is supplied through the domestic pipeline behind the water storage tank. This design can be based on actual need and select the water supply mode, and is more nimble and convenient. When the weather is sunny, the collector is closed by the cover plate, so that rainwater collected in the collector is prevented from evaporating; when the weather is rainy or cloudy, the collector opens the cover plate, closes the grating plate, prevents large leaves or large particles from falling into the collector, prevents the occurrence of the condition of pipeline blockage, greatly prolongs the service life of the device, is very convenient to replace the filter screen on the grating plate, can simply replace the filter screen by 2 modes, has low price, and can filter finer particles by the filter holes which are gradually decreased layer by layer.
