Description
Technical field
The present invention relates to agricultural drop irrigation technology, especially a kind of for effectively filtering agricultural drop irrigation water in drip irrigation system and the filter of self-cleaning can being realized.
Background technology
Drip irrigation utilizes plastic conduit that water is about aperture on 10mm hollow billet or water dropper by diameter to deliver to crop root and carry out localized irrigation.It is the most effective a kind of Water Saving Irrigation Mode of current drought and water-scarce area, and the utilization rate of water can reach 95%.Drip irrigation is comparatively sprayed and is had higher water-saving and yield-increasing effect, in conjunction with fertilising, can improve fertilizer efficiency more than one times simultaneously.Be applicable to fruit tree, vegetables, industrial crops and warmhouse booth to irrigate, also can be used for field crop irrigation in the place of drought and water shortage.Its weak point is the easy fouling of water dropper and blocking, if filter effect is undesirable, impurity and dirt easily enter pipe-line system, the delivery port of blocking dropping head, affect normally carrying out of drip irrigation work, particularly affect the service life of drip irrigation pipe, therefore tackle water source and carry out strict filtration treatment.
Filter is the key equipment that drip irrigation system normally works, mostly filter conventional is at present well strainer, namely filtered by inner cylindrical filtration, after a long time use screen pack can amass full impurity, just need cleaning or more offer the same old stuff but with a different label, and mostly the method for present cleaning or replacing is to cut off all power supplys, is opened by the cover of filter, screen pack take out cleaning or change, this manual mode seem very bother, time-consuming.
There is the filter solved the problem in prior art, as CN104815470A discloses a kind of spray drop filling cage type filter and using method thereof, comprised filter frame, screen pack, screen pack be placed in filter frame, also comprise backwash casing.Above-mentioned disclosed technology contents is in fact set up back purge system on the basis that existing top filters net cage, by backwash casing, regular backwash is carried out to screen pack, although this structure can regularly can be cleaned screen pack, solve screen pack impurity too much, reduce the problem of drip irrigation pipeline blocking, but structure too complex, adds Productive statistics cost.
In addition, CN203494294U discloses a kind of drop irrigation filter, comprise tank body, in the upper and lower that the mutually isolated only middle part of tank body part communicates, its middle and upper part is provided with screen pack, upper portion side wall is provided with delivery port, wherein bottom is positioned at the place of communicating and is provided with centrifuge tube, lower sides is provided with water inlet, the bottom of described tank body is connected with desilting tank, main shaft is provided with hairbrush by connecting wall, and the brush of hairbrush and the inwall of described screen pack contact, and the part that described main shaft is positioned at outside cover is connected with handwheel.Said structure is the hairbrush having installed handwheel drive in screen pack, utilize and rotate handwheel realization to the cleaning of filtering meat, although this rotating brush can clean screen pack at any time, but, people can not judge when effectively clean exactly, can not realize automatic cleaning, more can not accurately judge time length, automaticity is too low.
