Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate Accompanying drawing describes in detail as follows:
Referring to Fig. 1~Fig. 3, a kind of rain water on roof vertical filter unit, including overflowing of being arranged on outdoor rain standpipe 1 Flow tube 3, filter 5 and autocontrol valve 4;Described outdoor rain standpipe 1 is provided be sequentially arranged from top to bottom overflow Mouth and overflow inlet are put in flow export, filter;Being provided with filtering bodies 12 in described filter 5, described filter 5 is provided with into water Mouth 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 Filter with described outdoor rain standpipe 1 is put mouth and is connected, and the outlet of described filter 5 is positioned at the top of described filtering bodies 12, The outlet of described filter 5 connects and has 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, described autocontrol valve 4 be positioned at described filter put mouth and Between described overflow inlet;The entrance of described overflow pipe 3 and described overflow outlet is connected, the outlet of described overflow pipe 3 and Described overflow inlet connects, and 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 described filtering bodies The top of 12.Described filtering bodies 12 is the quartz sand using particle diameter to be 0.5-1.2mm or activated carbon formation.Described overflow The entrance of pipe 3 is connected by the overflow connecting tube 9 being obliquely installed with described overflow outlet, entering of described overflow connecting tube 9 Mouth is relatively low, exports higher, and the inclination angle of described overflow connecting tube 9 is 45 °.It is provided with support in the lower section of described filtering bodies 12 Net 13, described support net 13 is supported by supporting ring flat-plate 14, is arranged over fixing net 11, institute in described filtering bodies 12 State fixing net 11 and described support ring flat-plate 14 is fixed on the housing of described filter 5.
Use of the present utility model: being in open mode at rainy initial stage autocontrol valve 4, rainwater passes through rain Water pipe 1 enters city planting ductwork.After rainwater continues for some time, autocontrol valve 4 cuts out, and rainwater is through outdoor rain Standpipe 1 enters in filter 5, then carries out reverse filtration in filtering bodies 12, and the rainwater after purification is through discharge purified water Pipe 7 enters in water storage module or water tank.When running into heavy rain, rainwater instantaneous velocity, flow are very big, and outdoor rain is stood Water level in pipe 1 can uprise, and causes the surface of filtering bodies 12 to produce the biggest pressure.For protecting the safety of filtering bodies, in mistake Filter 5 is provided above an overflow pipe 3, and the peak level in the outer rain leader downspout 1 of control room, overflow connecting tube 9 is designed to When upwards the purpose of 45 ° is to prevent normal precipitation, rainwater is drained by overflow pipe, when the minimum threshold force, exceedes overflow and goes out The rainwater of open height is directly discharged from overflow pipe 3, enters city planting ductwork.Overflow pipe 3 is provided above vent valve 2 and prevents shape Become siphon, by whole filtration system and atmosphere.After rainfall stops, autocontrol valve 4 can be opened, and now filters Water above body 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 by spiral shell Bolt is fixed on the housing of filter.When needing manual flushing filtering bodies 12 through some cycles, first by flowing water Valve 6 Closing, 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.Use between crown cap 10 and filter Ring flange connects, and as changed filtering bodies 12, is opened by crown cap 10.
Although preferred embodiment of the present utility model being described above in conjunction with accompanying drawing, but this utility model not office Being limited to above-mentioned detailed description of the invention, above-mentioned detailed description of the invention is only schematically, is not restrictive, this The those of ordinary skill in field, under enlightenment of the present utility model, is being protected without departing from this utility model objective and claim In the case of the scope protected, it is also possible to make a lot of form, within these belong to protection domain of the present utility model.
