The dmp filter clarifier
Technical field
The utility model relates to water treatment, especially a kind of dmp filter clarifier.
Background technology
In the vast rural area of China, hundreds of millions of peasant that also living does not mostly also set up reliable running water feed system.And along with being widely used of chemical fertilizer, agricultural chemicals, herbicide, the surface water that some are local and underground water are all polluted, and ensure that the safety of drinking water exceedes the difficulty of feeling sleepy.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of dmp filter clarifier, and it collects natural rainfall, through filtration, purification, provides the clean water that can drink safely.
The technical scheme that its technical problem that solves the utility model adopts is: from top to bottom, pipeline is passed through in the catchment covers bottom, water intaking valve is communicated with the top of filter, pipeline is passed through in the filter bottom, outlet valve is communicated with storage tank top, by being close to siphunculus, near valve is with the pipeline on water intaking valve top and the pipeline communication on outlet valve top, blow-off pipe, the pipeline communication on blowoff valve and filter top, exhaust-valve is equipped with in the storage tank bottom, clean water valve is equipped with at the middle part, the built-in two-layer filter medium of filter, lower floor is crushed stone, the upper strata is husky, 20~50 millimeters of the particle diameters of crushed stone, the built-in filter screen of catchment covers.
The beneficial effects of the utility model are that simple in structure, heavily fortified point is durable for a long time, only depend on flow by gravity, need not extra power, rainwater can be become drinkable clean water through behind the multiple filtration, and energy backwash blowdown, be particluarly suitable for lacking the vast rural area use of clean water.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
In the embodiment shown in fig. 1, from top to bottom, catchment covers 1 bottom is by pipeline 2, water intaking valve 3 is communicated with the top of filter 4, filter 4 bottoms are by pipeline 2, outlet valve 7 is communicated with storage tank 8 tops, by being close to siphunculus 5, near valve 6 is communicated with the pipeline 2 on water intaking valve 3 tops with the pipeline 2 on outlet valve 7 tops, blow-off pipe 14, blowoff valve 13 is communicated with the pipeline 2 on filter 4 tops, exhaust-valve 9 is equipped with in the bottom of storage tank 8, clean water valve 10 is equipped with at the middle part, filter 4 built-in two-layer filter mediums, lower floor is crushed stone 11, the upper strata is husky 12,20~50 millimeters of the particle diameters of crushed stone 11, catchment covers 1 built-in filter screen 15.
During normal the use, water intaking valve 3, outlet valve 7 are opened, near valve 6, exhaust-valve 9, clean water valve 10, blowoff valve 13 are closed, rainwater enters catchment covers 1, by flow by gravity, filters rear water via pipeline 2 by filter screen 15, water intaking valve 3 enters filter 4, through sand 12, crushed stone 11 is filtered again, and last clean water flows into storage tanks 8 by pipeline 2, outlet valve 7 discharge filters 4.Backwash blowdown operation: close water intaking valve 3, outlet valve 7, open near valve 6, blowoff valve 13, rainwater enters catchment covers 1, after filter screen 15 filtrations, water is via being close to siphunculus 5, and near valve 6 enters filter 4 bottoms, and water is again via crushed stone 11, the clear Xian's deposit of husky 12 reverse flow, sewage flows out from filter 4 tops, finally by being discharged by blow-off pipe 14, blowoff valve 13.
