One) safety is high: compared to other rainwater filtering device, the purpose of design overflow pipe is exactly when meeting with rough sledding, it is ensured that the normal operation of filter, it is to avoid hydraulic pressure is excessive washes out filter body.
Two) good filtration effect: the rainwater that this filter filters is the rain water on roof after initial Split-flow, and pollution level itself is not high, can be selected for the quartz sand of little particle diameter or activated carbon in the selection of filter medium, makes effluent quality good.
Three) simple in construction: the control of the ingenious utilization automatic valve of this system, rain early-stage split-flow and backwash spoil disposal utilize outdoor rain standpipe to realize, and reduce construction cost, and achieve initial Split-flow, filtration and backwash integration.
Four) maintenance is installed convenient: this device adopts commercially available pipe fitting tubing, easy maintenance is installed.Water meeting auto-flushing filtering bodies owing to the present invention adopts reverse filtration, after rainfall stops, above filtering bodies, it is not necessary to often carry out artificial backwash.When through certain filter cycle, it is necessary to during artificial backwash, water pipe can be accessed the flushing valve on filter top, rinse directly down, save man power and material, can effectively reduce use cost.
In sum, the present invention is arranged on outdoor rain standpipe, mainly in rain water on roof, carrying early-stage rainwater stream abandoning function and backwashing function, good filtration effect, it is easy to rinses, clear up, it is simple to construction and installation.

Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example, and it be as follows to coordinate accompanying drawing to describe in detail:
Referring to Fig. 1～Fig. 3, a kind of rain water on roof vertical filter unit, including the overflow pipe 3 being arranged on outdoor rain standpipe 1, filter 5 and autocontrol valve 4；Described outdoor rain standpipe 1 is provided with the overflow being sequentially arranged from top to bottom export, filter and put mouth and overflow inlet；It is provided with filtering bodies 12 in described filter 5, described filter 5 is provided with water inlet and outlet, the water inlet of described filter 5 is positioned at the lower section of described filtering bodies 12, the water inlet of described filter 5 is put mouth with the filter of described outdoor rain standpipe 1 and is connected, the outlet of described filter 5 is positioned at the top of described filtering bodies 12, the outlet of described filter 5 is connected to discharge purified water pipe 7, described discharge purified water pipe 7 is provided with flowing water Valve 6；Described autocontrol valve 4 is arranged on described outdoor rain standpipe 1, and described autocontrol valve 4 is put between mouth and described overflow inlet in described filter；The entrance of described overflow pipe 3 is connected with described overflow outlet, and the outlet of described overflow pipe 3 is connected with described overflow inlet, is provided with bleeder pipe 2 at the top of described overflow pipe 3.
In the present embodiment, described filter 5 is additionally provided with flushing valve 8, and described flushing valve 8 is positioned at the top of described filtering bodies 12.Described filtering bodies 12 is the quartz sand adopting particle diameter to be 0.5-1.2mm or activated carbon formation.The entrance of described overflow pipe 3 is connected by the overflow connecting tube 9 being obliquely installed with described overflow outlet, and the entrance of described overflow connecting tube 9 is relatively low, exports higher, and the inclination angle of described overflow connecting tube 9 is 45 °.Being connected with support net 13 in described filtering bodies 12, described support net 13 is supported by supporting ring flat-plate 14, is arranged over fixing net 11 in described filtering bodies 12, and described fixing net 11 and described support ring flat-plate 14 are fixed on the housing of described filter 5.
The use of the present invention: being in open mode at rainy initial stage autocontrol valve 4, rainwater passes through rain pipe 1 and enters city planting ductwork.After rainwater continues for some time, autocontrol valve 4 cuts out, and rainwater enters in filter 5 through outdoor rain standpipe 1, then carries out reverse filtration in filtering bodies 12, and the rainwater after purification enters in water storage module or water tank through discharge purified water pipe 7.When running into heavy rain, rainwater instantaneous velocity, flow are very big, and the water level in outdoor rain standpipe 1 can uprise, and cause that the surface of filtering bodies 12 produces very big pressure.For protecting the safety of filtering bodies; it is provided above an overflow pipe 3 at filter 5; peak level in the outer rain leader downspout 1 of control room; overflow connecting tube 9 is designed to the purpose of upwards 45 ° when being prevent normal precipitation; rainwater is drained by overflow pipe; when the minimum threshold force, the rainwater exceeding overflow outlet height is directly discharged from overflow pipe 3, enters city planting ductwork.Overflow pipe 3 is provided above vent valve 2 and prevents from forming siphon, by whole filtration system and atmosphere.After rainfall stops, autocontrol valve 4 can be opened, and now the water above filtering bodies 12 can serve as backwashing water automatically.
Filter 5 includes crown cap 10, fixing net 11, filtering bodies 12 and support net 13.When installing filtering bodies 12, being placed on by support net 13 on support ring flat-plate 14, top uses fixing net 11 to fix filtering bodies 12, and fixing net 11 is bolted on the housing of filter.When needing manual flushing filtering bodies 12 through some cycles, first being closed by flowing water Valve 6, open the flushing valve 8 of filter top, inserted by water pipe and rinse from the top down, manual flushing is very convenient.Water and pollutant after flushing can enter city planting ductwork through outdoor rain standpipe 1.It is connected with ring flange between crown cap 10 and filter, as filtering bodies 12 need to be changed, crown cap 10 is opened.
Although the preferred embodiments of the present invention being described above in conjunction with accompanying drawing; but the invention is not limited in above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is merely schematic; it is not restrictive; those of ordinary skill in the art is under the enlightenment of the present invention; when without departing from present inventive concept and scope of the claimed protection, it is also possible to making a lot of form, these belong within protection scope of the present invention.
