Description
Technical field
The present invention relates to water-treatment technology field more particularly to a kind of rainwater filtration treaters.
Background technology
It is Tough questions that the current whole world faces that freshwater resources are in short supply, and freshwater resources are paid much attention to be subject to every country.
Rainwater is a kind of good freshwater resources, and natural rain water quality is good, and during the rainfall, rainwater is dropped in earth's surface, over the ground
Table is washed away, therefore containing substantial amounts of pollutant in the rainwater at initial stage, with the continuity of rainfall, pollutant contains in rainfall runoff
Amount is gradually reduced and tends towards stability.Using this rule, generally use rainwater flow-discarding device in rain processing system at present, to first
The more rainwater of phase pollutant is given it up, and middle and later periods rainwater-collecting is got up for domestic water.Rain water drainage fills at present
It is to carry out mechanical abandoned stream by the smaller principle of initial rainwater flow to put, however common flow abandoning apparatus can not be to the middle and later periods
Pollutant in rainwater is filtered processing, is also needed to after abandoned stream follow-up again to dmp filter processing.
The content of the invention
The present invention provides a kind of rain water drainage, dmp filter to solve the existing above problem of the prior art
The rainwater filtration treater of integrated form can realize rain water drainage, can also realize dmp filter.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of rainwater filtration treater, including cartridge filter, precipitation cylinder, the bottom of the cartridge filter is equipped with abandoned stream pipe, described
It is connected between cartridge filter, precipitation cylinder by diversion pipe, one end in cartridge filter is located on the diversion pipe and is equipped with filter screen, it is described
The side of cartridge filter is equipped with water inlet pipe, and the side of the precipitation cylinder is equipped with outlet pipe, and the water inlet pipe, outlet pipe are above leading
Flow tube；Bearing plate is equipped in the cartridge filter, the top surface of the bearing plate is connected by the side wall of three springs and cartridge filter, institute
The inner end for stating water inlet pipe is equipped with water outlet sleeve, and towards the top surface of bearing plate, the center of the bearing plate is set the opening of the water outlet sleeve

Lower end be equipped with for the abandoned stream seal of tube weighted spherical ball.
When not intaking in cartridge filter, position is top under the action of the spring for bearing plate, and spacing ball pulls slide bar to cause at this time
Weighted spherical ball is separated with abandoned stream pipe, and abandoned stream pipe is in opening state；The initial stage of raining, rainwater enter from water inlet pipe in cartridge filter, due to
Initial stage water is smaller (silt impurity is more in initial rainwater), and the water flowed out at water outlet sleeve is smaller to the impact of bearing plate, abandons
Flow tube is in opening state, and the high rainwater of impurity content directly exhausts at abandoned stream pipe；With the progress of rainfall, water inlet pipe enters
Water increase and keep stable, bearing plate receives larger rain-impact power, generates downward displacement, at this time weighted spherical ball decline
Abandoned stream pipe is closed, the water in cartridge filter enters from diversion pipe in precipitation cylinder, by strainer when rainwater passes through diversion pipe
Filtering, filters out large granular impurity in rainwater, still also has little particle impurity into the water in precipitation cylinder, and little particle impurity sinks
It forms sediment to the bottom of precipitation cylinder, the rainwater of relative clean is discharged from water outlet pipe part is used for domestic water；Rain stopping time, the water in water inlet pipe
The impact of bearing plate is reduced, bearing plate moves up a distance under the action of the spring, so as to moving slide-bar by weighted spherical ball
It is promoted, abandoned stream pipe is in opening state, so as to which the impurity for remaining in cartridge filter bottom be exhausted.

Structure, the sealing column and abandoned stream ligament coordinate, and taper choke is equipped at the inner wall of the water outlet sleeve, when piston is to moving up
After dynamic a distance, spacing ball is sealed with taper choke, sealing column is separated with abandoned stream pipe.Strainer is in filter process, impurity
Mesh can be blocked, is reduced so as to cause the flow in diversion pipe, the liquid level in cartridge filter constantly raises, so as to promote piston upward
It is mobile, when piston moves extension rod, slide bar is driven synchronously to move up, sealing column is gradually extracted out of abandoned stream pipe, when spacing ball enters
When at the taper choke of water outlet sleeve (water outlet sleeve is substantially at the state of closed state or water yield very little), sealing column is from abandoned stream
Extracted completely in pipe, abandoned stream pipe is in opening state, at this time the water in precipitation cylinder be back to by diversion pipe in cartridge filter and from
It exhausts, so as to carry out backward erosion once to strainer, while the impurity of cartridge filter bottom is exhausted together, with mistake at abandoned stream pipe
The discharge of water in filter cylinder, the liquid level in cartridge filter decline, and piston moves down, and sealing column reinserts abandoned stream pipe interior sealing, goes out
Water jacket is opened completely, then normal operation；After a period of time, when strainer is blocked again, above-mentioned action can be repeated automatically, from
And automatically cleaning is carried out to strainer.
