Be provided with perspective window 12 and valve 13 in the header bottom.Externally also can check the situation of machine intimate at any time, also can take out the rainwater sample that flows in the machine in case of necessity.
The bottom of the top and header of settler is communicated with, and also is communicated with the bottom of filter.Other all is an airtight casing.The perspective window 12 of the setting on the header, valve 13, inlet valve 141 also are in the casing of an integral body 14.Fix with screw with upper-part.As long as unclamping screw so just can separate settler.
In working order down, the early-stage rainwater by header is along with the continuous rising of water level, will flow in the filter 40 and filter pure water pipe 50 outflows by being connected with offlet 20 then.
Be provided with the constant current plate 311 that a lot of openings 312 form in settler 30 inside, several constant current plates 311 intersect has in length and breadth formed the constant current parts.Because the constant current parts are provided with a lot of openings, the rainwater of Liu Ruing just can intersect the multi-faceted constant current plate 311 that flows through in length and breadth like this, thereby has controlled the flow velocity of water and made suspended solid obtain better precipitation.Numerous materials when so also just having avoided early-stage rainwater to flow into stop up the phenomenon of filter 40.Along with the continuous inflow of rainwater, water level rises gradually, and hydraulic pressure constantly raises, and will flow in the filter through sedimentary rainwater and filter.
Side below settler 30 is provided with water port 32, and the inner water-break pipe 33 that aperture 332 is set by certain distance has been installed on the water port.When rainfall amount reduces or after rainfall stops, rainwater will be discharged by water-break pipe 33 when remaining in settler.Water port 32 lower ends are connecting the water-break flexible pipe 35 that is connected with offlet 20.
Certainly such design can make the sub-fraction of the rainwater that flows into settler directly flow out by the water-break pipe, but because the diameter of aperture is very little, the effusive rainwater of filtered is and a few part, can impact environment.
For prevent throw out with water level raise may block water-break hole 331 in the indoor design of water-break pipe 33 buoyancy aid 34 that is interconnected of each water-break hole, be provided with eradicator 341 on the buoyancy aid.Buoyancy aid carries out lifting with the change of level of rainwater in the water-break pipe, the eradicator that the buoyancy aid outside is provided with carries out lifting together with water-break hole 331, just suspended solid has been got rid of in lifting process, thereby has been made the work of carrying out that the water-break pipe can continue.
The water-break pipe of telling about above 33 also can be installed 2-3 according to length, and recombinant gets up to use.
For example the water-break pipe has been installed 3 groups situation, and is shown in Figure 5: the first water-break pipe 33a with water port connects, the second water-break pipe 33b is installed in the above again, and the 3rd water-break pipe 33c is installed again.And in the inside of each water-break pipe, the inside in water-break hole 331 is provided with the buoyancy aid 34 that a plurality of eradicators 341 are formed.
After being made up of 3 groups of water-break pipes like this, no matter the withdrawal nozzle in which water-break pipe of 1-3 produces and stops up, and rainwater can also be discharged residual water by other holes that are communicated with it.
In addition, upper middle position at the 3rd filtering layer 43 is provided with bracket 431, mid-way at the cap 44 of the superiors is provided with lead screw 45, drags between seat and the lead screw to couple together, and is the phenomenon generation of floating and overturning with the rising of water level for the filtrate that prevents 1-3 like this.
In addition, be provided with absorption rainwater smeary adsorption element 60 at the middle portion of header, as shown in Figure 6.
It is to concentrate to central authorities for the rainwater that makes inflow that adsorption element is designed to upper coarse and lower fine shape, has so not only controlled the speed of water but also has made the suspended solid in the rainwater be adsorbed net 62 absorption parts.The seston that can also prevent simultaneously bottom when water level is too high is again on the adverse current.
And this adsorption element also is arranged in the water shoot, because when the rainwater water level raise, some can flow in the water shoot, will directly not discharge if the adsorption element rainwater is installed, and pollutes.
The machine of forming by above each parts of the present invention like this, after directly connecting with the road surface drainage pipe, rainwater flows into by header during rainfall, and the restriction that is controlled plate can be directly from the water shoot outflow, thus suitable header flows down.By the absorption of adsorption element, flow into again and carry out constant current and precipitation in the settler, because the constant current plate has a lot of holes,, also can carry out good constant current and abundant precipitation even the water yield is big like this.
Along with the continuous inflow of rainwater, water level raises like this, and hydraulic pressure raises, and will make all contaminations obtain removing successively through the filtration of 1-3 filtering layer in the filter through sedimentary rainwater.Purifying waste water after the filtration flows in the water shoot by pure water pipe discharges.
If rainfall continues always, make water level reach the topmost of water shoot, rainwater will spill out by water shoot, because early-stage rainwater has passed through precipitation and has filtered, the pollution substance content of later stage rainwater reduces greatly, also can not cause too big influence to environment even directly discharge by water shoot.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; though but on its shape or structure, do any variation, every have identical with a utility model or akin technical scheme, all within its protection domain.
