Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 ~ Fig. 3, a kind of dmp filter accumulation device, comprise and be arranged on catch-basin on both sides, road surface or ground, greenery patches 1, described catch-basin is provided with water inlet pipe 3, outlet pipe 7 and well lid 2, the partition wall 11 that bottom is unsettled is provided with in described catch-basin, described catch-basin is divided into collecting well 4 and filter well 8 by described partition wall 11, capping 6 is provided with at described filter well 8 top, the flow channels 12 being communicated with described collecting well 4 and described filter well 8 is formed below described partition wall 11, the bottom of described filter well 8 is reduce gradually to the bottom of described flow channels 12 from its borehole wall domatic 13, described outlet pipe 7 is positioned on the borehole wall of described filter well 8, described water inlet pipe 3 is positioned on the borehole wall of described collecting well 4, filtration is provided with on the top of described filter well 8, described filtration is positioned at the below of described outlet pipe 7, be connected with mud pipe 10 bottom the borehole wall of described collecting well 4, described mud pipe 10 is provided with gate valve 9.
In the present embodiment, described filtration comprise multiple from top to bottom successively arrange filter 14, each described filter 14 comprises the screen frame 14-1 be fastened on mount pad 15, upper strata gauze wire cloth 14-2, the filter membrane 14-3 and lower floor gauze wire cloth 14-4 that set gradually from top to bottom are housed in described screen frame 14-1 inner clip, between described screen frame 14-1 and described mount pad 15, be provided with rubber seal, described mount pad 15 is formed on the borehole wall of described filter well.Filter 14 surrounding adopts rubber seal rings for seal, and prevent permeable, filter membrane 14-3 is clipped in the middle by upper and lower two-layer gauze wire cloth, can avoid it in filter process because flow action deforms.Filter 14 arranges 3-4 layer.
Described filtration is obliquely installed.Can enlarge active surface, strengthen filter effect, secondly also can reduce the distance of filtration to well head, convenient cleaning and replacing filter membrane.The lower end of described screen frame 14-1 and described mount pad 15 adopt hinge 16 hinged, between the upper end and described mount pad 15 of described screen frame 14-1, be formed with closing component structure.To facilitate the fixing of filter 14 and cleaning.The filter area of multiple described filter 14 increases from bottom to up successively, convenient rotation during to ensure successively to rinse.The membrane filtration hole of multiple described filter 14 reduces from the bottom to top successively.To meet work principle of filter, reach good filter effect.In the present embodiment, filter membrane 14-3 adopts filter cotton to be formed, and the thickness of filter cotton is 0.03-0.05m.Conveniently safeguard, the borehole wall of described collecting well 4 and described filter well 8 is all provided with and marks time 5.
When said apparatus uses, rainwater flows into collecting well 4 by water inlet pipe 3 or well lid 2, due to atmospheric pressure and law of connected vessels, current can oppositely flow into filter well 8 by the bottom of collecting well 4, and after filtration 14, clear water is flowed out by outlet pipe 7, silt and pollutant are trapped, fall the bottom of filter well, along domatic landing in collecting well, regularly discharge from mud pipe 10.
After use after a while, for preventing filtration 14 from blocking, can closing component structure between opened filter disc 14 and mount pad 15, layering is upwards turned over filter disc 14, carries out backwash.Arrive after application life, because filtration 14 is comparatively near apart from well head, staff 5 can enter filter well 8 and changes filter membrane 14-3 by marking time.Also 5 can enter catch-basin and carry out periodic test by marking time at ordinary times.
Although be described preferred embodiment of the present utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model aim and claim protect, can also make a lot of form, these all belong within protection domain of the present utility model.
