Abstract
A kind of roof rain water retracting device with backwashing system.Layer of sand, metalling and collection water pipe are laid in the gutter of both sides, roof, and rainwater flows through layer of sand, metalling filtration treatment along the gradient on roof, after the rainwater after filtration is collected by the aperture on bottom collection water pipe, flow into aqua storage tank through collector pipe and water-main；After running 10 15 days, when layer of sand, metalling have impurity to block, close water-main valve, open backwash bypass valve and backwashing pump, the water of aqua storage tank is transported to roof through water-main and collects water pipe, aperture ejection from collector pipe, carries out backwash to layer of sand, metalling, and waste water is discharged by roof drainage system.After backwash 15 minutes, turn off backwash bypass valve and backwashing pump, open water-main valve simultaneously, restart to filter rainwater.This device collection roof rain water collecting, processing, be stored in one, the most effectively, install, easy to use, operating cost is low, applied range, can be that city and rural area provide domestic water and municipal water use, saving water resource.
Description
(1) technical field:
Patent of the present invention relates to a kind of roof rain recovery system, particularly to a kind of roof rain with backwashing system
Apparatus for recovering.
(2) background technology:
China's water resource per capita and shortage thereof, hydropenia become serious restriction Chinese society economic development " bottleneck " it
One.Originating for city and rural water, essentially from subsoil water and rivers and lakes, the water resource of some areas is the most withered
Exhausting, water supply cost increases.Therefore find a kind of technology that existing rainwater resource is recycled and just seem increasingly important.China ground
Territory is wide, and rainwater resource enriches, and rainwater-collecting is done scientific disposal, is available for resident and makees domestic water and municipal water use, also reduce
Urban ground runoff, alleviates sewer discharge pressure.Roof and other platform rainfalls recycle before illustrating wide application
Scape, has included multinational research range in.Chinese patent (CN20506289 U) discloses a kind of roof rain water collecting processing system.Should
Rainwater is entered rainwater-collecting tank by collection bucket by device, plant carries out after being filtered spraying and irrigates.This device is received
All being delivered to irrigate case after the rainwater treatment of collection, and use water pump power conveying, there is application single, installation cost is high, place
Reason high in cost of production problem.
(3) summary of the invention:
The technical problem to be solved is: provide a kind of roof rain water retracting device with backwashing system.
Layer of sand 1, metalling 2 and collect water pipe 3 and be laid in the gutter of both sides, roof, rainwater flows through layer of sand 1, broken along the gradient on roof
Rock layers 2 filtration treatment, after the rainwater after filtration is collected by the aperture on bottom collection water pipe 3, flows through collector pipe 3 and water-main 4
Enter aqua storage tank 6；When layer of sand 1, metalling 2 have impurity to block, close water-main valve 5, open backwash bypass valve 7 with anti-
Flushing pump 8, is transported to roof by the water of aqua storage tank 6 through water-main 4 and collects water pipe, and the aperture ejection from collector pipe 3, to layer of sand
1, metalling 2 carries out backwash；After backwash terminates, close backwash bypass valve 7 and backwashing pump 8, open water-main valve
Door 5, restarts to filter rainwater.
Further, after a kind of roof rain water retracting device with backwashing system runs 10-15 days, layer of sand 1, rubble
When layer 2 has impurity clogging, needing layer of sand 1, metalling 2 are carried out backwash 1-5 minute, backwashing water is from roof drainage system
System flows out；Layer of sand 1 should be expanded 20-30% by backwash hydraulic pressure, to reach backwash effect.
Further, described water-main 4 a diameter of 100-150 millimeter；Collect water pipe 3 a diameter of 50-80 millimeter, collect water
Having the circular hole of a diameter of 1.5-2 millimeter on pipe 3, percent opening is 5-10%.
Further, the thickness of described layer of sand 1 is 400-500 millimeter, and sand grains size is 3-5 millimeter.
Further, the thickness of metalling 2 is 200-300 millimeter, and rubble size is 20-50 millimeter.
Compared with existing rain collector, this patent collection and treatment device is arranged in the roof gutter being seen everywhere,
Device is simple, easy for installation；Rainwater first passes around sandstone and rubble gravity filtration, removes in rainwater large granular impurity and various outstanding
Float matter etc.；Rainwater after filtration enters aqua storage tank through collecting pipe and water-main, and the volume of aqua storage tank can stop 1 day with rainwater
Time calculates.Abnormal flavour and antibacterial can be removed with disinfection in aqua storage tank, after precipitation, can make through water system
For resident living water and municipal water use.This device collection roof rain water collecting, process, be stored in one, the most effectively, install,
Easy to use, operating cost is low, applied range, can be that city and rural area provide domestic water and municipal water use, save water
Resource, has the biggest Social and economic benef@.
(4) accompanying drawing explanation
Fig. 1 is a kind of roof rain water retracting device structural representation with backwashing system.
In Fig. 1: 1: layer of sand, 2: metalling, 3 collection water pipes, 4: water-main, 5: water-main valve, 6: aqua storage tank, 7: recoil
Wash bypass valve, 8: backwashing pump.
(5) specific embodiments
Below in conjunction with patent of the present invention accompanying drawing, the detailed description of the invention of patent of the present invention is further described.
On rainy day, rainwater first flows through, along the gradient on roof, the layer of sand that thickness is 500 millimeters, and sand grains size is 3-5 millimeter,
Being 300 millimeters of metallings subsequently into thickness, rubble size is 20-40 millimeter, and rainwater after filtering is 80 by base diameter
Millimeter is collected the aperture on water pipe and is collected, and hole diameter is 1.5 millimeters, and percent opening is 5-10%；Rainwater is collected by collector pipe
Aqua storage tank, a diameter of 100 millimeters of water-main is flowed into by water-main.Rainwater can stop 1 day time at aqua storage tank, at aqua storage tank
In add disinfectant and process, remove abnormal flavour and antibacterial in water, after precipitation, can be through water system, as resident living water and city
Political affairs water.When, after plant running 15 days, when layer of sand, metalling have impurity to block, rainwater is not dirty smooth, now, closes water-main
Valve, then opens backwash bypass valve and backwashing pump and the water of aqua storage tank is transported to roof collection water pipe, through collector pipe
On aperture ejection, layer of sand, metalling are carried out backwash, waste water is discharged by roof drainage system.After backwash 2 minutes, then
Close backwash bypass valve and backwashing pump, open water-main valve simultaneously, restart to filter rainwater.
