Technical field
The utility model relates to rainwater treatment device, especially relates to a kind of rain water drainage filter.
Background technology
The rain early-stage split-flow device being applied in Rainwater collection system is intended to remove the pollutant in early-stage rainwater, rubbish such as the higher organic pollution of the contained concentration of rainfall early-stage rainwater, suspension.Rain early-stage split-flow device filter effect is directly connected to the quality of the collected rainwater quality of whole rain water collecting system.
And current rain early-stage split-flow device is comparatively complicated in structure design, with actuating unit in the situation that, will inevitably produce corresponding energy consumption, this is uneconomical and unacceptable for user.And also there is functional more single problem in initial Split-flow device.
Utility model content
The purpose of this utility model is exactly in order to address the above problem, and a kind of have initial Split-flow and pre-filter function, simple in structure and unpowered and realize the rain water drainage filter of zero energy consumption are provided.
To achieve these goals, the utility model adopts following technical scheme:
Rain water drainage filter, it has one and limits the working cavity forming and the entery and delivery port (1 communicating with this working cavity by housing (10), 2), it is characterized in that, described working cavity is provided with the screen pack (5) between entery and delivery port, described working cavity bottom has a sewage draining exit (6) and communicates with sewage draining exit and supply the movable blowdown chamber (8) of sealed spheroid (3), this blowdown chamber is connected in blow-off pipe (7), and described sewage draining exit place is provided with the annular chinampa (4) being connected with sealed spheroid.
As further improvement of the utility model is, described blowdown chamber is a diminishing undergauge structure of bore near sewage draining exit place.
As further improvement of the utility model is, the curved structure of described screen pack.
As further improvement of the utility model is, described sewage draining exit and entery and delivery port drop are less than 30cm.
As further improvement of the utility model is, described sealed spheroid is hemisphere.
As further improvement of the utility model is, described entery and delivery port coaxial arrangement.
As further improvement of the utility model is, described blowdown chamber is a taper blowdown chamber.
The utlity model has following beneficial effect:
(1) in housing, be provided with arc screen pack, can realize on-line filtration function.
(2) annular chinampa is positioned at housing middle part, and buoyancy is large, and centre can overcurrent, and fluid trafficability characteristic is good.
(3) housing embedded with conical blowdown chamber, places semicircle sealed spheroid in chamber, bell and ball sealer physical efficiency seal completely.
(4) sealed spheroid is hemisphere, lightweight, is not only beneficial to sealing but also can steadily rests in blowdown well floor.
(5) sewage draining exit and Inlet and outlet water drop are less than 30cm, are convenient to discharge dirt.
Accompanying drawing explanation
Fig. 1 is rain water drainage filter top view.
Fig. 2 is rain water drainage filter cut-away view one.
Fig. 3 is rain water drainage filter cut-away view two.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figures 1 to 3, rain water drainage filter (hereinafter to be referred as " device "), its have one by housing 10 limit the working cavity that forms and with entering that this working cavity communicates, delivery port 1, 2, whole device has a base 9, described working cavity is provided with between entering, screen pack 5 between delivery port, after rainwater enters working cavity, the horizontal plane of rainwater can bleeder due to intake-outlet coaxial arrangement, now, the lower edge of screen pack at least will there be rainwater horizontal plane, just there will not be rainwater inherent filtration portion off the net process and cannot realize filtering function completely, described working cavity bottom has a sewage draining exit 6 and communicates with sewage draining exit and supply the blowdown chamber 8 of sealed spheroid 3 activities, this blowdown chamber is connected in blow-off pipe 7, blow-off pipe is directly by dirt discharging device, described sewage draining exit place is provided with the annular chinampa 4 being connected with sealed spheroid, between sealed spheroid and annular chinampa, can be connected with flexible attachment components, also can connect with the parts that are rigidly connected, here select floating ball rod 11 to connect.
Owing to need to completing the shutoff of sealed spheroid for sewage draining exit, described blowdown chamber is a diminishing undergauge structure of bore near sewage draining exit place, when rising to sewage draining exit place, sealed spheroid directly whole blowdown chamber and working cavity are isolated, comparatively it is desirable to, described blowdown chamber is a taper blowdown chamber.
Because the working cavity of whole device is a cylindrical-shaped structure, so, the curved structure of described screen pack, arcuate structure can effectively filter rainwater, and it is maximum that filter area reaches.
For ease of blowdown, described sewage draining exit and entery and delivery port drop are less than 30cm.
Consider weight issue, described sealed spheroid is hemisphere, and the buoyancy on annular chinampa need be greater than the gravity of sealed spheroid, and sealed spheroid is made and all can with flexible material or metal material.
During work, rainwater flows in flow abandoning apparatus housing 10 from water inlet 1, and the serious rainwater of precontamination flows in taper blowdown chamber 8 from sewage draining exit 6, then emits through blow-off pipe 7.Flow abandoning apparatus annular chinampa 4, sealed spheroid 3 are along with taper blowdown chamber 8, the interior water level of housing 10 improve and rise, when sealed spheroid 3 rises to the top in taper blowdown chamber 8, close flow abandoning apparatus sewage draining exit 6, after sewage draining exit 6 is closed, water (flow) direction changes, rainwater flows to delivery port 2 through arc screen pack 5 and enters collection conduit, complete the abandoned stream to the serious rainwater of precontamination, after rainfall finishes, flow abandoning apparatus annular chinampa 4, sealed spheroid 3 be along with taper blowdown chamber 8, the interior water level of housing 10 decline and decline, thereby get back to original state before rainfall.
The foregoing is only preferred embodiment of the present utility model, protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvement of carrying out under the prerequisite that does not depart from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
