Description
Technical field：
The invention belongs to drip irrigation equipment technical field, more particularly to a kind of filter for drip irrigation water process.
Technical background：
Drip irrigation is according to crop water requirement, by pipe-line system and the douche on hollow billet, by water and crop
The irrigation method that the nutrient needed is instilled in the soil of crop root zone dropwise.Drip irrigation does not destroy soil texture, soil Nei Shui, fertilizer, gas,
The hot good condition for often keeping being suitable for plant growth, evaporation loss is small, does not produce surface runoff, almost no deep layer is oozed
Leakage, is a kind of irrigation method of water-saving, is adapted to promote in the area of the unsuitable normal irrigation mode such as water shortage, hillside fields.
Due in drip irrigation equipment water dropper it is small-sized, when in the water for flowing through dropper band contain granule foreign when, water dropper pole
Easily block, cause water dropper to fail；Therefore drip-irrigation water needs to carry out filtration treatment before pumping, prevents particulate matter from being set into drip irrigation
It is standby.In existing equipment, generally filtered only with laminated filtering device, still there is calcium in water, magnesium ion fouling and clogging
The possibility of water dropper, it is such as simple that calcium and magnesium removal is carried out using ion exchange resin, then easily cause sodium in water, potassium content liter
Height, long-term use can cause the salinization of soil, and such as water body is carried out using pellicle to remove salt treatment, cost and treatment effeciency completely
It is difficult to meet drip irrigation needs.
The content of the invention：
A kind of laminated filtering device goal of the invention for drip irrigation equipment of the invention：There is provided one kind can low cost go water removal
The laminated filter of middle calcium, magnesium ion, prevents drip irrigation emitter from being failed caused by fouling and clogging.
A kind of laminated filtering device for drip irrigation equipment, including housing, inner support disk, filter core；Wherein, housing is closing
Tubular transparent shell, lower side taps into water pipe, bottom and outputs the mouth of a river；Inner support disk is arranged in housing, its central openings
And outlet pipe is downwardly extending through delivery port；Filter core is clamped between inner support disk and case top；It is symmetrical centered on filter core
Multilayer barrel structure, it includes cultivating aperture plate, inactivating device, the first laminated filtering layer, amberlite lipid layer and the from outside to inside
Two laminated filterings layer；Inactivating device is made up of shadow shield and the multiple uviol lamps being centrosymmetrically arranged.
During work, water is injected by lower housing portion water inlet pipe, in interior support plate lower zone unhurried current preliminary sedimentation rear steering
On, pass sequentially through after cultivation aperture plate, extinguishing device, the first laminated filtering layer, amberlite lipid layer and second lamination filter layer
Inner support Pan Zhongyangkaikongchu is imported, is drawn by outlet pipe.
In said process, uniform algae on aperture plate is cultivated, because the growth of algae needs illumination, carbon dioxide
And mineral ion, in the case where housing uses transparent material and ensures that illumination is sufficient, it can absorb a part of calcium ions and magnesium ions simultaneously
Effectively gas concentration lwevel in reduction water, reduces bicarbonate ion concentration, and then form remaining calcium ions and magnesium ions in water
Calcium carbonate, magnesium carbonate solid particle, are filtered out in follow-up two layers of laminated filter；Remaining a small amount of calcium ions and magnesium ions are by ion in water
Exchanger resin processing replaces with sodium potassium ion, so as to realize the complete softening to hard water, realization prevents follow-up drip irrigation pipeline, water dropper
The function of middle fouling and clogging.The cooperation of uviol lamp and shadow shield can be cultivated at aperture plate in the case of algae to first not damaging
The biology adhered on laminated filtering layer is inactivated, and prevents the first laminated filtering layer working face from biological pollution occur.
It is preferred that, case top is provided with ring cover, cultivates aperture plate, uviol lamp, amberlite lipid layer and is separately mounted to
Ring cover bottom, it is possible to removed upwards with ring cover, it is convenient to cultivating aperture plate, algae, uviol lamp and amberlite
The replacing maintenance work of fat.
It is preferred that, to prevent uviol lamp accidental damage, and inactivation region is fixed, filter core also includes Central Symmetry cloth
The multiple uviol lamp pillars put, are fixedly mounted between case top and inner support disk, and each uviol lamp of shade is corresponded to respectively.
It is preferred that, filter core also includes the husky laminated filtering layer of resistance, and resistance sand laminated filtering layer is arranged on filter core outermost, used
Light transmissive material makes, and prevents little particle solid dirt infringement configuration aperture plate.
It is preferred that, shadow shield is venetian blind type shadow shield, and its blade profile is L-type.
A kind of beneficial effect of laminated filtering device for drip irrigation equipment of the invention：By being set for laminated filtering device
The post processing structure such as structure and inactivation, ion exchange resin is cultivated, the water demineralization of low cost is realized, and reduce soil salt
Alkalize possibility.
