Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, be the Venturi tube sprinkler irrigation fertilization apparatus structure schematic diagram of the utility model embodiment, present embodiment comprises: Development of Venturi Fertilizer Applicator 1, control valve, the fertile jar of storage, inlet channel 4, outlet conduit 5, trunk line 6 and moisturizing pipeline 7.
Wherein, hickey is all adopted in the import of Development of Venturi Fertilizer Applicator 1 and exit, so that be connected with outlet conduit 5 with inlet channel 4; Development of Venturi Fertilizer Applicator 1 is provided with a fertilzer sucking pipe 11; Control valve comprises the valve 21 that is arranged on the trunk line 6, be arranged on the valve 22 on the inlet channel 4, be arranged on valve 23 and the valve 24 that is arranged on the moisturizing pipeline 7 on the outlet conduit 5, valve 21 is used for regulating the fluid flow of trunk line 6, valve 22 and 23 is used to regulate the flow pressure of the import and export of Development of Venturi Fertilizer Applicator 1, to reach the different purposes of inhaling fertile flow of adjusting, valve 24 is used to regulate liquid is entered the fertile jar 3 of storage by moisturizing pipeline 7 flow.
Again as shown in Figure 2, it is the secondary jar structure schematic diagram of the utility model embodiment, the fertile jar of the storage of present embodiment comprises main jar 31 and secondary jar 32, main jar 31 is one not have the hydrostatic column of end face, its height is less than the bottom surface diameter, such as highly can being about 1/2～1/3 of bottom surface diameter, and the bottom surface diameter can be in 1m～1.5m scope; The hydrostatic column that does not have end face that is a height greater than the bottom surface diameter for secondary jar 32, such as highly being 1.2～1.6m, the bottom surface diameter is about 1/3～1/4 of a height, material can be common plastics; Secondary jar of 32 top offer a moisturizing hole 321 far from about the 0.1m of top, and secondary jar 32 is connected with moisturizing pipeline 7 by moisturizing hole 321, can receive liquid in the moisturizing pipeline 7 to replenish the liquid in the fertile jar of storage; On the moisturizing hole 321 screen pack is installed, be used for impurity screening and do not have the dissolving fertilizer; Position apart from about the secondary jar of 32 bottom 0.05m has out axisymmetric two holes, wherein is connected with fertilzer sucking pipe 11, be used for receiving Development of Venturi Fertilizer Applicator 1 fertilizer be referred to as to inhale fertile hole 322; What non-return valve was installed is referred to as recovery holes 323, recovery holes 323 can only be used in the fertilising later stage water by secondary jar 32 of main jar 31 inflow, the water in master's jar 31 is introduced secondary jar 32 avoid waste, need equally screen pack to be installed, be used for the fertilizer that impurity screening and not have dissolves at opening part.The material of main jar 31 and secondary jar 32 can be plastic material, metal material or the like, only otherwise get final product with the fertilizer chemically reactive.
When using sprinkler irrigation fertilization device of the present utility model to carry out sprinkler irrigation fertilization, first valve-off 22 and valve 23 are opened valve 21, carry out the clear water sprinkling irrigation, can remove other remaining fertilizer of possibility in the pipeline simultaneously, to avoid chemical reaction, reduce fertilizer efficiency; Add water-soluble fertilizer liquid or liquid fertilizer then in secondary jar 32, the amount of adding tries not to surpass 4/5 of main jar 31 volumes, can add several times if amount is many; Open the valve 24 (being a control valve) on the moisturizing pipeline 7 then, make water pass through secondary jar 32 and flow in main jar 31, as calculated as can be known, the fluid flow that flows through in trunk line 6 is 35-50m
3During/h, the fertilizer-sucting quantity of Development of Venturi Fertilizer Applicator 1 is 3-4m
3/ h, so control valve 21 makes flow of inlet water remain on 4m
3About/h; When filling for main jar 31, open valve 22 and 23, begin to inhale fertile by fertilzer sucking pipe 11; Owing to inlet pressure, inhale parameter such as solution face height and all remain unchanged, so fertilizer-sucting quantity tends towards stability, and at this moment, but the aperture of appropriate change valve 24 is regulated rate of water make-up, makes water overflowing to main jar 31 from secondary jar 32 slowly; Can also change fertilizer-sucting quantity according to the fertilising needs by the aperture of control valve 21,22 and 23, can carry out coarse adjustment by the aperture that changes valve 21, the aperture that changes valve 22 and valve 23 can be finely tuned.After fertilizer-sucting quantity changed, suitably control valve 24, the balance of the liquid level that makes it to keep to apply fertilizer, and what exceed again overflows to main jar 31; When the water in secondary jar 32 becomes limpid, illustrate that fertilizer is sucked by major part, this moment, valve-off 24 stopped moisturizing, when secondary jar 32 liquid levels drop to a certain degree, main jar 31 water enters secondary jar 32 by recovery holes, and the water and the fertilizer that overflow like this in main jar 31 have obtained recovery; After fertilising finished, valve-off 22 and 23 got final product, and reply is at last cleaned for main jar 31 and secondary jar 32.
As can be seen from the above embodiments, the Venturi tube sprinkler irrigation fertilization device that the utility model provides, be set to main jar and secondary jar by storing up fertile jar, moisturizing pipeline and fertilzer sucking pipe are worked simultaneously and can be made the height of secondary jar liquid surface constant, and remain on a higher value, thereby the throat pressure of Development of Venturi Fertilizer Applicator is increased, inhaling fertile pressure reduces, easier suction is fertile, and operating mode can keep relative stability, and has also reduced the cavitation coefficient, cavitation factor, Toma coefficient of device; The excessive simultaneously water in main jar can be recovered to by non-return valve in the secondary jar in the fertilising later stage, had improved fertilizer utilization ratio, had reduced waste, helped the stable of operating mode.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
