Abstract
The utility model relates to a capsule type chemical fertilizer pot for a drip irrigation system, in which a capsule in arranged to separate the chemical fertilizer and the water for pressing out the chemical fertilizer solution in the capsule by utilizing the differential pressure between an inlet and an outlet for fertilizing a drip irrigation system.
Description
The utility model relates to a kind of drip irrigation system that is used for, and discharges the device of fertilizer solution in pipeline at the hinge place.
Existing design has three classes:
(1) simply differential.The fertilizer solution jar respectively has an inlet tube and outlet tube, links to each other with the drip irrigation water main by valve, and regulating the valves makes water inlet pressure greater than water outlet pressure, and fertilizer solution flows into main slowly in jar under this pressure reduction.Its shortcoming is that the earlier dense back of solution is rare, and rate of fertilizer application is inhomogeneous.
(2) main suction-type.Make the local section flip-flop on main, pipeline dwindles section part, and flow velocity produces negative pressure greatly, utilizes this negative pressure with fertilizer pot solution suction main.Its shortcoming is to have increased the loss of flood peak on the main.
(3) water pump adding pressure type.In fertilizer pot and main junction, fertilizer pot solution is pumped into main by a little pump.Obviously, this has increased equipment investment.
In the fertilizer pot that China uses at present, the overwhelming majority belongs to first type, and is poor because of result of use, throws aside mostly.
Consider the deficiency of above-mentioned all kinds of design, the utility model has adopted in the chemical fertilizer tank body method that fertilizer solution and water is separated with rubber capsule, utilize the pressure reduction of water inlet pipe and water outlet pipe, solution in the capsule is extruded, make solution concentration not change in time, to guarantee the degree of uniformity of fertilising, do not increase extra power simultaneously yet and cause the excessive loss of flood peak in the main.
Be further elaborated below in conjunction with accompanying drawing.Figure is a capsule-type fertilizer pot longitudinal diagram.
With reference to figure, 1. novel this capsule-type fertilizer pot that comprises of the design has a metal case, and rubber capsule 2..
The dress fertilizer solution is water between capsule and the metal case in the capsule, 4. 5. is connected with the main of drip irrigation system by valve.
4. and 6. by regulating the valves 3.,, make fertilizer solution in the capsule by different release rate, enter main slowly 5..(seeing accompanying drawing)
Claims (1)
- The fertilizer pot that is used for drip irrigation system is characterized in that being equipped with in the jar capsule of containing fertilizer solution, and water and solution are separated, and utilizes the pressure reduction of intake-outlet, and solution in the capsule is extruded.
