Embodiment 1:
As shown in Figure 1, the embodiments of the present invention 1 provide a kind of rainfall runoff pollution cutting device, including main box 1, Filter screen 2,3, two installation lids 4 of screen pipe and outlet pipe 5;
The upper end of the main box 1 offers access hole 11, and partition 12, the partition 12 are provided in the main box 1 The main box 1 is divided into gathering ground 13 and filtering area 14, water inlet 15, institute are offered on the side wall of the gathering ground 13 It states water inlet 15 to be connected to external inlet for stom water, gap 16 is offered on the partition 12, the filter screen 2 is horizontally placed on It is detachably connected in the gathering ground 13 and with the inner wall of the gathering ground 13, the height of the filter screen 2 is higher than the water inlet The height of mouth 15, and it is lower than the height of the gap 16, the gap 16 passes through overflow pipe 161 and the screen pipe 3 Side wall connection, two installation lids 4 are removably covered on the both ends of the screen pipe 3, set on the side wall of the screen pipe 3 Multiple filter hole 31 are equipped with, the screen pipe 3 is set in the filtering area 14, and the bottom of the filtering area 14 offers water conservancy diversion Slot 17 offers the water outlet 18 being connected to the diversion trench 17 on the side wall of the filtering area 14, and the outlet pipe 5 is set to The main box 1 is outer and is connected to the water outlet 18, and the outlet pipe 5 extends towards waters to be discharged.
Rainfall runoff pollution cutting device provided by the utility model, the course of work are as follows: rainwater is passed through by external inlet for stom water Rain pipe 6 enters gathering ground 13, and water level increases gradually in gathering ground 13, when being increased to filter screen 2, filter screen 2 to rainwater into Row filtering, by pollutant intercept in filter screen 2 hereinafter, rainwater pass through filter screen 2 be increased at gap 16 again, pass through overflow pipe 161 enter in screen pipe 3, and the filter hole 31 on screen pipe 3 is for re-filtering to rainwater, and filtered rainwater enters filtering area It in 14, and is flow at water outlet 18 by diversion trench 17, is expelled in waters to be discharged finally by outlet pipe 5.Use process In, it needs periodically to clear up pollutant.When clearing up the pollutant in gathering ground 13, filter screen 2 is disassembled, Then it is cleared up, having cleared up again will be in the installation to gathering ground 13 of filter screen 2.When clearing up filtering area 14, it will pacify Capping 4 is opened, and the pollutant in screen pipe 3 is dug out, then installation lid 4 is covered.
Specifically, water inlet 15 is connected to by water pipe 6 with external inlet for stom water, so that the rainwater in inlet for stom water is introduced collection Pool 13, inlet for stom water are the structures for collecting surface runoff, it is the The Small Well for being set to underground, and upper part and ground are flat, are had On it, rainfall runoff enters well room by the gap on rain grid to rain grid lid, and inlet for stom water uses in the utility model Existing construction, the utility model are not related to the improvement to inlet for stom water.
Rainfall runoff pollution cutting device provided by the utility model, is provided with filter screen 2 and screen pipe 3 filters twice, filtering Effect is good, and it is strong to cut dirty effect.Meanwhile filter screen 2 is horizontally disposed, prevents compared to being vertically arranged, horizontally disposed mode is not easy to send out Raw pollutant blocking, avoids pollution the blocking of object blocking filter screen 2, influences filter effect and efficiency.The same level of screen pipe 3 is set It sets, and is provided with multiple filter hole 31 on the side wall of screen pipe 3, the blocking of pollutant can be equally prevented, because of pollutant It usually can be only piled up in the bottom of screen pipe 3, the filter hole 31 of 3 top of screen pipe still may be implemented to filter.Furthermore gathering ground 13 and filtering area 14 all there is memory action for rainwater, simple precipitation can be carried out to rainwater, reinforce cutting a dirty effect, avoid simultaneously Rainwater can not be discharged in time cause surface gathered water too much, guarantee the patency of rainwater flowing.The utility model can guarantee to cut On the basis of dirty effect, guarantees to cut dirty efficiency, avoid surface gathered water phenomenon.
Preferably, as shown in Figure 1, being provided with oil suction medium 7 in the gathering ground 13.
The grease that oil suction medium 7 is sucked out in rainwater is set, on the one hand rainwater is purified, on the other hand prevents grease pair In the damage of filter screen 2 and screen pipe 3.It needs to be replaced regularly for oil suction medium 7 to guarantee oil absorbing effect.
Preferably, as shown in Figure 1, the aperture of the filter hole 31 is less than the aperture of mesh 21 on the filter screen 2.
Mesh 21 on filter screen 2 is larger, carries out by-pass filtration to rainwater, and filter hole 31 is smaller, carries out second level to rainwater Filtering.
Preferably, as shown in Figure 1, the bottom of the filtering area 14 is set as skewed, the one of the separate water outlet 18 End is higher than close to one end of the water outlet 18.
It sets skewed for the bottom of filtering area 14, helps to be expelled in waters rapidly after dmp filter is complete, avoid Rainwater results in blockage in filtering area 14, causes the refluence of rainwater.Preferably, strainer can be also set at gap 16, prevented Pollutant flows backward to gathering ground 13 from filtering area 14.
Preferably, as shown in Figure 1, the screen pipe 3 is supported in the filtering area 14 by support pier 8.
Screen pipe 3 is supported by support pier 8, so that the filtering surface of screen pipe 3 is bigger.Preferably, the filtering Hole 31 is uniformly distributed along the circumferential direction of the screen pipe 3, so that all directions of screen pipe 3 can be filtered.
Preferably, as shown in Figure 1, the quantity of the access hole 11 is two, two access holes 11 are respectively arranged at The gathering ground 13 and the top of filtering area 14 are covered with cover board 19 on two access holes 11.
Cover board 19 is set on access hole 11, can prevent the pollutant in air from floaing and cause secondary pollution into main box, Meanwhile it can prevent pedestrian from accidentally falling into main box, it is ensured that pedestrains safety.
Preferably, the quantity of the water inlet 15 be it is multiple, multiple water inlets 15 respectively from the rain of different outsides Mouth of a river connection.
Multiple water inlets 15 are set, so that the rain pipe of different directions can enter main box 1 and carry out cutting dirty operation.
Preferably, as shown in Figure 1,14 bottom of the gathering ground is placed with the sludge collecting box 9 of upper end opening, the sludge collecting box 9 On offer the inlet opening 91 being connected to the water inlet 15, be provided on the sludge collecting box 9 described for pulling out sludge collecting box 9 Gathering ground 13 reels bar 92.
For the ease of quickly transporting the pollutant in gathering ground 14, sludge collecting box 9 is set, and filter screen 2 carried out rainwater When filter, pollutant concentration is accommodated in sludge collecting box 9, when needing to clear up pollutant, under filter screen 2 is dismantled out of gathering ground 13 Come, pulling reels bar 92, and sludge collecting box 9 is pulled out, is then cleaned up pollutant from sludge collecting box 9, the collection that will finally empty Dirty case 9 is put back into gathering ground 13, and filter screen 2 is reinstalled in gathering ground 13.Since sludge collecting box 9 fills pollutant When heavier-weight, therefore can be pulled it by hoisting apparatus, such as crane.
Specific embodiment of the present utility model described above does not constitute the restriction to scope of protection of the utility model. Any other various changes and modifications that any technical concept according to the present utility model is made should be included in practical In novel scope of protection of the claims.
