Embodiment Construction

[0014] The implementation method takes the method of microfiltration and disinfection device for microirrigation as an example. This method has four stages of filtering:

[0015] One is to pass the water entered by the water inlet pipe 3 through the filter net box 1 to achieve the first stage of filtration;

[0016] The ozone generated by the filtered water through the ozone sterilizer 4 is inhaled by the water pump unit 8, and the water body is pre-sterilized and sterilized; the water inlet pipe 3 is connected to the check valve 2 to prevent the backflow of the liquid medicine after the machine is shut down; Add water pipe and valve 7 to the fertilizer medicine tank 6, and stir; open the fertilizer medicine pipe and valve 5, use the negative pressure of the water pump inlet pipe to inhale the fertilizer medicine liquid, and the mouth of the fertilizer medicine nozzle is also equipped with a filter cover to trap the liquid. Granules, in a system with a large control area, two...

Abstract

The present invention relates to a fine-filtering and sterilizing device for micro-irrigation and a method thereof. The device comprises a filtering net cage, an ozone disinfector, a fertilizing device assembly, a water pump assembly, a sand-rock filter, a lamination type filter and a membrane filter. The essential point of designing is that the purpose of fine-filtering and sterilizing for micro-irrigation through the organic combination of the components and assemblies. The method of the invention is provided with a four-stage filtering and is available. The fine-filtering and sterilizing device of the invention has the advantages of lower manufacturing and application cost, water resource saving for more than 50%, promotion to the high yield and high quality of crop, and facility for being generalized in countryside. The fine-filtering and sterilizing device of the invention is one of advanced facilities applying sprinkling irrigation, fine sprinkling irrigation and trickle irrigation for developing high-efficient ecological agriculture.

Description

technical field [0001] The invention belongs to the fields of agricultural scientific irrigation and water-saving irrigation, and is a filter and disinfection device for micro-irrigation, including micro-spray irrigation and drip irrigation systems, for purifying water. technical background [0002] Practices at home and abroad have proved that advanced facilities such as sprinkler irrigation, micro-sprinkler irrigation, and drip irrigation must be used in the construction of modern agriculture and the development of efficient ecological agriculture. % above water resources. Micro-sprinkler irrigation and drip irrigation are simple and reliable techniques for increasing farmers' income, and they are also water-saving measures with the greatest potential. [0003] However, due to the small aperture of micro-irrigation nozzles and drip irrigation drippers (about 1mm), the requirements for water purification are very high. At present, general treatment equipment cannot meet th...
