Description
Technical field
The utility model relates to drip irrigation filter technology field, is a kind of cheek formula filter.
Background technology
China is one of country of lack of water in the world, and per capita water resources quantity is merely 1/4 of world average level, and the water resources quantity that the unit cultivated area occupies is equivalent to 2/3 of world average level.Present situation year, water supply capacity was about 5,600 hundred million m
3, wherein about 4,000 hundred million m3 of agricultural water amount account for 70% of national total water amount, and the efficiency of water application of agricultural water are merely 40%～45%.Agricultural water inefficiency and shortage of water resources and to deposit be the key constraints that further promotes China's overall productivity in agriculture.Drip irrigation is a state-of-the-art irrigation technique on the our times, has that water saving, saving of labor, water conservation, guarantor are fertile, energy-conservation, the remarkable result of raising the output, promotes the development of agricultural production.But; Drip irrigation requires not contain dirt and the impurity that causes douche to stop up in the irrigation water, and in fact any water source all contains various impurity, if the water source is not carried out sedimentation and filtration; Will certainly cause obstruction in various degree to drip irrigation system, even cause scrapping of whole drip irrigation system.So it is the key that guarantees the normal operation of drip irrigation system that irrigation water is carried out purified treatment.Drip irrigation system can utilize filter to remove dirt and impurity in the irrigation water, and drip irrigation can be described as the heart of whole drip irrigation system with filter.
The filter that at present drip irrigation system is commonly used generally has granular membrane, 4 kinds of the husky separator (centrifugal type filter) of spiral-flow type water, sand filter and laminated filters.(1), granular membrane: nylon or stainless (steel) wire are fixed on the support, and mesh size generally is no more than water dropper water stream channel diameter 10% to 20%.This filter is applicable to the filtering inorganic material, and organic substance and biological impurities are prone to stop up.When some build up of dirt after on the screen cloth, can significantly descend through the pressure of filter, at this moment tackle filter screen and implement flushing; (2) the husky separator (centrifugal type filter) of spiral-flow type water: pressure flow is tangentially flowed into circle or conical filtering jar, rotate, under centrifugal action, the impurity heavier than water sinks around shifting to gradually, and clear water rises, the water sand separation.Sandrock filter can the continuous filtration high sediment concentration dripping irrigation water, but the impurity close or lighter with water proportion, filtration is not obvious.Therefore have only when the proportion that is divided particle is higher than water and be only effectively.This kind equipment is generally as the first order treatment facility of filtration system; (3) sand filter: in filtering tank, put 1.5 millimeters sand gravels, when water flows, remove foreign material in gravel to 4 millimeters thick.This filter mainly is applicable to the filtration of organic impurities, be characterized in having the ability of very high removal dirt, but this equipment is more expensive, to having relatively high expectations of management; (4) lamination filter: generally be the stack of the disk of trough of belt to be compressed form, remove impurity when water flows in lamination slot.And can unclamp lamination and remove cleaning impurity.This filter is applicable to organic and poly-doped impurity filters.Above-mentioned four kinds of irrigation systems filter commonly used is mainly used in well water, Ku Shui, water in a canal, river and opens wide the water filtration that contains the grains of sand, organic matter, mud scum, mud in the water surface.The various filters aperture of using in traditional irrigation system is stopped up and big this problem of the loss of flood peak in order to solve; The general sandstone filter and the husky separator of spiral-flow type water or well strainer of adopting is arbitrarily made with combined type sandstone filter, to adapt to different spray drip irrigation requirements.At present, the drip irrigation filter plant mainly is to be main with the centrifugal combination of screens formula filter that adds, but this type filter exists complex structure, hydraulic loss greatly with, the more high deficiency of price.
