Description
Technical field
The present invention relates to agricultural irrigation technologies, are specifically related to a kind of method that drop irrigation filter realizes self-cleaning.
Background technique
China's distribution of water resources is extremely unbalanced, and few, the Dong Duoxi few situation in the more north in south is geographically presented, presents on the time
Spring and summer is more, and other times are few, brings uncertain influence to the agricultural production in China.
In the area of some water resources shortages, many arable lands are in the condition of anhydrous irrigation, therefore rational utilization of water resources
It is the developing direction of agricultural water.
Trickle irrigation is that water is sent to plant root by aperture on diameter about 10mm hollow billet or drip head using plastic conduit
The technology of localized irrigation is carried out, it is a kind of most effective Water Saving Irrigation Mode, and the utilization rate of water is filled up to 95%, and with other
Irrigating mode and comparing has higher water-saving and yield-increasing effect, while can improve one times of fertilizer efficiency or more in conjunction with fertilising.Drip irrigation technique is existing
It is being suitable for a variety of occasions, is being especially suitable for water resources shortage area crop irrigation.Trickle irrigation is insufficient compared with other irrigation methods
Place be that drip head is easy to block because of solid impurity in water or dirt, if filter effect is undesirable, impurity and dirt hold
Easily entering pipe-line system, the water outlet of clogging drip irrigation head influences being normally carried out for trickle irrigation, especially influences the service life of drip irrigation pipe,
Therefore reply water source is filtered processing.
Existing trickle irrigation filter is mostly well strainer, i.e., is filtered by internal filter screen, is using one
After the section time, full impurity can be accumulated on filter screen, it is necessary to clean filtrate in filter screen or replacement filter screen, existing cleaning side
Method is to shut down artificial cleaning, and this cleaning way is extremely complex, and needs manually to carry out, laborious time-consuming, current self-cleaning side
There are mainly two types of formulas, and it is brush that one is motor drivens, and another kind is hydro powered suction type.
Motor driven brush type filter needs to configure motor, and retarder, structure is complicated, at high cost, and reliability is low, using not
It is convenient；Hydro powered suction type filter is using the impurity on suction type element kit removal strainer, and structure is increasingly complex, filtering
Effect needs to be further improved, and scavenging period is long, and element kit is expensive, once damage, replacement trouble is existing in a word
Self-cleaning be that filter is primarily present the problems such as structure is complicated, at high cost, reliability is low.
Summary of the invention
To solve current filter, there are self-stripping unit, structure is complicated, the low technical problem of reliability, public affairs of the invention
The method opened a kind of structure of drop irrigation filter and realized self-cleaning.
To reach above-mentioned purpose, the technical solution adopted by the present invention are as follows:
A kind of the step of method that drop irrigation filter realizes self-cleaning, self-cleaning are as follows:
S1: starting water pump, water flow into filter from water inlet；
S2: starting ultrasonic transducer；
S3: deflection cone is encountered into the water in drop irrigation filter and point is flowed around；
S4: the space between shell and filtering body is divided quickly by water filling around；
S5: enter drop irrigation filter water pressure head effect under, water along filtering body surface spiral shape water conservancy diversion
The spiral space flowing that piece is formed, the flowing in space of the water between shell and filtering body are in swirl shape；
S6: in spiral space flow process of the water along the spiral vane formation on filtering body surface, most of water is logical
It crosses filtering body to enter drip tray and then flow out drop irrigation filter through outlet pipe, the carrying of fraction water cannot pass through the solid of filtering body
Impurity and dirt enter filtering body lower space under the water conservancy diversion of spiral vane, then flow out irrigation filtering by return pipe
Device is discharged into water source or in swag.
In above process, the solid impurity under the collective effect of the pressure head of water and ultrasonic transducer, in water
With dirt under the drive in swirl shape flowing water, it is not easy deposition and is attached in filtering body, and between shell and filtering body
Space is larger, and filtering body lower space is also larger, the return pipe of the connection be also at most under position, volume phase can be passed through
Biggish solid impurity and dirt are compared, avoids solid impurity and dirt in conventional filter that from can only being attached to ten in filtering body
The susceptible to plugging problem of partial volume, makes filtering body be not easy to be blocked, and ensure that the long-time service of drop irrigation filter.
The drop irrigation filter realizes the method for self-cleaning, and there are one recoil methods: when necessary, can by outlet pipe water pump,
Water inlet pipe and return pipe do return pipe, start ultrasonic transducer, can further clean up the filtration core of filtering body.
A kind of drop irrigation filter produced according to the method described above, including shell, filtering body and ultrasonic transducer, it is described outer
Shell is in cylindrical body, including barrel-shaped shell and end cap, and the end cap central is welded with water inlet pipe, and the water inlet pipe passes through the end cap,
It is deep into internal a part, position horizontal direction of the barrel-shaped shell close to bottom is provided with a return pipe, and the filtering body is in
Cone, top sub-fraction are deflection cone, and other parts are filtration core, and conical drip tray, drip tray central portion are arranged at bottom
Position is welded with outlet pipe outward, and the outlet pipe passes through barrel-shaped shell bottom centre, and welds together with barrel-shaped shell bottom, described
Filtering external surface is provided with spiral vane, and the surrounding of the barrel-shaped shell is provided with the ultrasonic transducer, it is described into
Water pipe connects water pump, and the outlet pipe connects droping irrigating pipe, and the return pipe leads to water source or swag.The irrigation filtering uses
When should place vertically, i.e., for water inlet above, water outlet is below.
The filtered water flowed out of the water outlet pipe is used for trickle irrigation, to ensure that drip head is not blocked, drip head is permanent
It uses.
