Description
Technical field
The utility model is related to agricultural irrigation filter plant technical field, is a kind of fine deposit fine filtering device and anti-stifled formula drop
Fill system.
Background technology
Agricultural irrigation mode generally can be divided into traditional surface irrigation, common sprinkling irrigation and slight irrigation.Traditional surface irrigation bag
Border irrigation is included, irrigates through furrow, basin irrigation and flood irrigation, but often water consumption is big, water utilization rate is relatively low for this kind of irrigation method, is that a class does not conform to very much
The agricultural irrigation mode of reason.In addition, commonly sprinkler irrigation technique is irrigation method more universal during Chinese agriculture is produced.But common sprinkling irrigation
The utilization ratio of the water of technology is not also high.The micro- irrigation technique of modern agriculture includes microspray irrigation, drip irrigation, infiltrating irrigation etc..These irrigate skill
The general water-saving performance of art is good, water utilization rate is high compared with traditional irrigation pattern.Wherein, drip irrigation is by the drop on hollow billet
Arrow, water dropper, drip irrigation zone or other outlet type douches drop by drop, uniformly and slowly instill water near crop root zone
Form of pouring water in soil.It is small due to the flow that drips, and slowly infiltrates, and mainly acts on and spreading by capillary pulling power, is to save the most
One of water and effective irrigation method.
Agricultural irrigation water mainly includes underground water and surface water, and it all contains more impurity, it is impossible to directly use it for
Drip irrigation, generally requires to carry out before this filtration treatment to prevent clogging drip irrigation system, but existing filtering technique is by multiple differentiation
Alternate, although preferable effect is achieved in the filtering of underground water, but for the increasingly complex surface water of impurity composition,
The problem of its meeting clogging drip irrigation system can not be still overcome at present.For the filtration treatment of surface water, commonly use in the prior art
Have the different mode of following four：
1）Centrifugal filter and the well strainer using Manual-cleaning are installed additional after pump, wherein for the mud in underground water
Sand grain is highly effective, but the web-roll core of well strainer is easily damaged, and web-roll core needs to tear open web-roll core in replacing and cleaning
Installed again after going out, it is cumbersome, waste time and energy；When it is used for surface water, because the water quality of surface water is increasingly complex, after it is filtered
Still more thin mud sand grain is contained in water, and the use process of drip irrigation system is intermittent process, is stagnated in drip irrigation system
During state, thin mud sand grain will be deposited, so that clogging drip irrigation system；
2）Sandrock filter and the well strainer using Manual-cleaning are installed additional after pump, for the organic matter in surface water

Also there is filtrate and easily run sand in stone filter, filtrate needs annual replacing, and floor space is especially big, and the pressure loss is at 7 meters to 10
Rice between, the web-roll core of well strainer is easily damaged, and web-roll core need to split out web-roll core in replacing and cleaning after install again,
It is cumbersome, waste time and energy；
3）Install the well strainer of energy automatic back-washing additional after pump, its floor space is small, and crushing is within 5 meters, water after filter
For drip irrigation system effect preferably, but still there is thin mud sand grain and can deposit, so that the phenomenon of clogging drip irrigation system；And it is right
Frequent backwash occurs in the water quality rich in silt, non-silt impurity, causes blowdown flow rate excessive, then causes drip irrigation system can not
Normally use；
4）Installed additional before pump can automatic back-washing well strainer, the irrigation water rich in non-silt impurity is served compared with
Good filter effect, and crushing can be reduced, but for still helpless rich in silt water quality, however it remains frequent backwash,
Thin mud sand grain can be deposited, so that the phenomenon of clogging drip irrigation system.
