Description
Technical field
The present invention relates to water-treatment technology field, more particularly to a kind of rainwater filtration treater.
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 by every country.
Rainwater is a kind of good freshwater resources, and natural rain water quality is good, and in rainfall, rainwater is dropped in earth's surface, over the ground
Table is washed away, therefore contains substantial amounts of pollutant in the rainwater at initial stage, and with the continuity of rainfall, pollutant contains in rainfall runoff
Amount is gradually reduced and tended 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 less principle of early-stage rainwater flow to put, but common flow abandoning apparatus can not be to the middle and later periods
Pollutant in rainwater carries out filtration treatment, is also needed to after abandoned stream follow-up again to dmp filter processing.
The content of the invention
The present invention is in order to solve existing above mentioned problem of the prior art, there is provided a kind of rain water drainage, dmp filter
The rainwater filtration treater of integrated form, rain water drainage can be realized, 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 provided with abandoned stream pipe, described
Connected between cartridge filter, precipitation cylinder by mozzle, one end on the mozzle in cartridge filter is provided with screen pack, described
The side of cartridge filter is provided with water inlet pipe, and the side of the precipitation cylinder is provided with outlet pipe, and described water inlet pipe, outlet pipe are above leading
Flow tube；Bearing plate is provided with 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 for stating water inlet pipe is provided 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 provided with for the abandoned stream seal of tube weighted spherical ball.
When not intake in cartridge filter, position is top under the action of the spring for bearing plate, and now spacing ball pulls slide bar to cause
Weighted spherical ball separates with abandoned stream pipe, and abandoned stream pipe is in open mode；The initial stage of raining, rainwater enter in cartridge filter from water inlet pipe, due to
Initial stage, water was smaller (silt impurity is more in early-stage rainwater), and impact of the water flowed out at water outlet sleeve to bearing plate is smaller, abandons
Flow tube is in open mode, and the high rainwater of impurity content is directly drained 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, produces downward displacement, and now weighted spherical ball declines
Abandoned stream pipe is closed, the water in cartridge filter enters in precipitation cylinder from mozzle, by filter screen when rainwater passes through mozzle
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
Form sediment to the bottom of precipitation cylinder, the rainwater of relative clean and discharged from water outlet pipe part for domestic water；Rain stopping time, the water in water inlet pipe
Impact to bearing plate reduces, and bearing plate moves up a segment distance under the action of the spring, so as to moving slide-bar by weighted spherical ball
Lifting, abandoned stream pipe are in open mode, so as to which the impurity for remaining in cartridge filter bottom be drained.

After a dynamic segment distance, spacing ball seals with taper choke, sealing column separates with abandoned stream pipe.Filter screen is in filter process, impurity
Mesh can be blocked, so as to cause the flow in mozzle to reduce, the liquid level in cartridge filter constantly raises, so as to promote piston upward
It is mobile, drive extension rod, slide bar synchronously to move up when piston moves, 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 mode or water yield very little), sealing column is from abandoned stream
Extracted completely in pipe, abandoned stream pipe is in open mode, now the water in precipitation cylinder be back to by mozzle in cartridge filter and from
Drain, so as to carry out backward erosion once to filter screen, while the impurity of cartridge filter bottom is drained 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, gone out
Water jacket is opened completely, then normal operation；After a period of time, when filter screen is blocked again, above-mentioned action can be repeated automatically, from
And automatically cleaning is carried out to filter screen.
