Description
Technical field
The utility model relates to water environment environment protection fields, and in particular to a kind of rain dirt separation structures.
Background technique
With the continuous development of society with the raising of human living standard, the black smelly outstanding problem of urban water-body seriously affected
The life of resident, the common people are to the demand in " clean river " and thirst for further strong.
City moisture to be treated is nature rainwater and two kinds of municipal sewage, and the pollution of natural rainwater is small, can directly arrange
Enter urban river system, the pollution of municipal sewage is big, and being directly discharged into river will cause pollution, needs to be collected into sewage treatment
System carries out certain processing just and can be carried out discharge.And when the rainy day, rainwater can also enter sewage collection system, due to rainwater
It is not required to be handled, flowing into sewage disposal system will increase processing cost, therefore city needs a kind of effective rain sewage diversion (rain
Dirt shunts, and is a kind of run-off system, refers to and separate rainwater and sewage, respectively with a pipeline, carries out discharge or subsequent place
The blowdown mode of reason.Rainwater can be exhausted directly to river by Storm Sewer Network and be sent to after sewage needs to collect by sewage network
Sewage treatment plant is handled, and is discharged in river again after water quality reaching standard, can prevent river contaminated in this way.) measure come to from
Right rainwater and municipal sewage are separated, to be respectively processed.
The main reason for black and odorous water formation, is precisely due to rain dirt mixed flow is discharged into pollution caused by river.In most cities
City, to confluence of rainwater and sewage status there is no shunting measure is implemented, although few area is provided with part flow arrangement to confluence of rainwater and sewage pipe,
Electric floating movable valve is set still without tackling the problem at its root, such as in cutting dirty flow abandoning apparatus, electric floating movable valve is long-term
Damage is easily caused in Sewage Environment, repair cost is very high；And generally in season fine or short of rain, electric floating movable valve is not
It needs repairing；And in plum rain season, electric floating movable valve spoilage is higher, at this time inconvenient maintenance again, and device occur cannot play
It is the phenomenon that its function affect, this to be completely dependent on automatically controlled device reliability and substantially reduce.

Detailed description of the invention
Fig. 1 is one figure of the embodiments of the present invention state；
Fig. 2 is two figure of the embodiments of the present invention state；
Fig. 3 is three figure of the embodiments of the present invention state；
In the figure, it is marked as collecting-tank 1；Grid 2；Desilting zone 3；Drainage area 4；Confluence of rainwater and sewage water inlet pipe 5；Drainpipe 6；Blowdown
Pipe 7；Sewage pipe water inlet 8；Floating drum 9；Floating valve 10；Settling pit 11；Slope 12；Well lid 13；
Specific embodiment
The utility model is further described below in conjunction with attached drawing.
As shown in Figure 1, a kind of rain dirt separates structures, including collecting-tank 1, grid 2, confluence of rainwater and sewage water inlet pipe 5, drainpipe
6, sewage pipe 7, sewage pipe water inlet 8 and the floating closed component for closing sewage pipe water inlet 8；The grid 2 is arranged
It is divided into the desilting zone 3 and drainage area 4 that left and right is separated by the inside of collecting-tank 1, and by 1 inner space of collecting-tank, the rain dirt is closed
The setting of water pipe 5 is flowed into 3 side wall of desilting zone, the setting of drainpipe 6 is being drained in 4 side wall of drainage area, the setting of sewage pipe 7
4 side wall of area and it is lower than 6 position of drainpipe, the sewage pipe water inlet 8 is arranged in 4 bottom of drainage area.
The floating closed component includes floating drum 9 and the floating valve 10 for connecting 9 bottom of floating drum, the floating valve 10
It is arranged in the sewage pipe water inlet 8.
Embodiment state one
As shown in Figure 1, sewage flows into collecting-tank 1 along confluence of rainwater and sewage water inlet pipe 5 when not having rainwater there was only municipal sewage,
Floating valve 10 is sunk to the bottom at this time, and sewage pipe water inlet 8 is in open state, and sewage flows into sewage pipe 7 through sewage pipe water inlet 8, after
Sewage treatment plant is sent by pipeline.Wherein grid 2 can filter off in sewage it is biggish suspension or floating material with anti-clogging sewage pipe
7, the silt in sewage is collected into settling pit 11, and the later period is facilitated to clear up.
Embodiment state two
As shown in Fig. 2, rainwater flows into collecting-tank 1 along confluence of rainwater and sewage water inlet pipe 5 when encountering water flow big row's Pluvial,
Because water flow is big, floating drum 9 and floating valve 10 float under the action of buoyancy, and floating valve 10 blocks sewage pipe water inlet 8,
Sewage pipe water inlet 8 is in closed state, and rainwater flows out collecting-tank through drainpipe 6.Wherein grid 2 can filter off biggish in sewage
It suspends or floating material is with anti-clogging sewage pipe 7, the silt in sewage is collected into settling pit 11, and the later period is facilitated to clear up.
Embodiment state three
As shown in figure 3, the liquid level in drainage area 4 gradually decreases, the buoyancy of rainwater is not enough to overcome floating closed component
Floating drum 9 and floating valve 10 gravity when, the floating valve 10 of floating closed component can drop to draining under the effect of gravity
4 bottom of area, sewage pipe water inlet 8 is in open state at this time, and the water in collecting-tank 1 flows into sewage pipe 7 through sewage pipe water inlet 8,
Sewage treatment plant is sent by pipeline afterwards.Wherein grid 2 can filter off in sewage it is biggish suspension or floating material with anti-clogging blowdown
Pipe 7, the silt in sewage are collected into settling pit 11, the later period are facilitated to clear up.
The working principle of this rain dirt separation structures is:
When rainfall is smaller, floating drum and floating valve drop by gravity, and floating valve opening, sewage is arranged from sewage pipe
Out；When rainfall is larger, the pit level that catchments rises, and floating drum is floated by buoyancy, and floating valve is closed, and rainwater is from draining
Pipe discharge.After rainfall, liquid level is by floating drum floating to drainpipe lower edge in collecting-tank, and floating valve and sewage draining exit enter water at this time
There is gap between mouthful, the water of collecting-tank flow to sewage pipe through sewage draining exit water inlet, and liquid level is gradually reduced, and floating drum declines with liquid level,
Restore to blowdown state.
The above is only the better embodiment of the utility model, not makees any form to the utility model
On limitation be not intended to limit the utility model although the utility model is disclosed above in a preferred embodiment thereof, it is any
Heat knows professional and technical personnel, is not departing within the scope of technical solutions of the utility model, when the method using the disclosure above
And technology contents make a little change or are modified to the equivalent implementations of equivalent variations, but all without departing from the utility model
The content of technical solution, according to the technical essence of the utility model to any simple modification made by embodiment of above, equivalent
Variation and modification, are still within the scope of the technical solutions of the present invention.
