Abstract
The invention discloses a self-filtering negative-pressure irrigation device. The self-filtering negative-pressure irrigation device comprises a water source container, an air collection cylinder is arranged nearby the water source container, the bottom opening of the air collection cylinder is connected with a filter cartridge through a sealing gasket and a clamp, a water outlet pipe is led out of the bottom of one side of the filter cartridge, the outer end of the water outlet pipe is connected with a plurality of connection pipes in parallel, each connection pipe is provided with at least two negative-pressure water feeders, a water suction pipe is connected between the upper side of the filter cartridge and the water source container and provided with an electromagnetic control valve, and a top cover of the air collection cylinder is provided with a negative-pressure switch and an air suction pipe respectively. According to the self-filtering negative-pressure irrigation device, water lower than the negative-pressure water feeders is supplied to roots of plants under the action of an atmospheric pressure difference by controlling negative pressure of the air collection cylinder, accurate control of the soil water content and continuous water supply are achieved, the water saving effect is good, manpower is saved, and the self-filtering negative-pressure irrigation device has wide application prospect.
Description
Technical field:
The present invention relates to and water, particularly a kind of Negative pressure irrigation device with inherent filtration function.
Background technology:
Negative pressure irrigation technology is the method for economizing on water most at present, negative pressure water supply device many employings potter's clay material, aperture is very small, if process bad filtration problem, very easily block, cause systemic breakdown, the power because of Negative pressure irrigation comes from the suction of soil, the loss of flood peak of filtration system has extreme influence to irrigation system, and the filtration problem therefore resolving Negative pressure irrigation has great significance to applying of Negative pressure irrigation of raising.
Summary of the invention:
The object of this invention is to provide a kind of inherent filtration Negative pressure irrigation device that effectively can solve Negative pressure irrigation filtration problem.
Technical scheme of the present invention completes as follows, a kind of inherent filtration Negative pressure irrigation device, it includes a water source container, it is characterized in that: a gas collecting jar with ground-on cover plate is installed near water source container, bottom gas collecting jar with ground-on cover plate, nozzle there is a cartridge filter with gasket seal and clamp connection, an outlet pipe is led at a side bottom of cartridge filter, outlet pipe outer end is parallel with many tube connectors, each tube connector is separately installed with at least two negative pressure water supply devices, suction hose is connected with on the upside of gas collecting jar with ground-on cover plate and between water source container, suction hose is provided with solenoid electric valve, gas collecting jar with ground-on cover plate top cover is separately installed with a negative pressure pressure switch and an exhaust tube.Cartridge structure is provided with fin on the inwall of cylinder, fin is placed with a filter stand, is filled with porous filter material, on filter stand, is provided with handle in filter stand.
The present invention is supplied to plant root the water lower than negative pressure water supply device by the negative pressure of domination set inflator under the effect of atm difference, realizes continuing to supply water to the accurate control of soil moisture content, and water-saving result is good, saving is artificial, is with a wide range of applications.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention; Fig. 2 is the partial sectional view of gas collecting jar with ground-on cover plate.
Detailed description of the invention:
Describe embodiment in detail by reference to the accompanying drawings, the present invention is provided with a gas collecting jar with ground-on cover plate 6 near water source container 1, bottom gas collecting jar with ground-on cover plate, nozzle is connected with a cartridge filter 11 with gasket seal 8 and clip 7, an outlet pipe 12 is led at a side bottom of cartridge filter, outlet pipe outer end is parallel with many tube connectors 13, each tube connector is separately installed with at least two negative pressure water supply devices 14, suction hose 2 is connected with on the upside of gas collecting jar with ground-on cover plate and between water source container, suction hose is provided with solenoid electric valve 3, gas collecting jar with ground-on cover plate top cover is separately installed with a negative pressure pressure switch 4 and an exhaust tube 5.Cartridge structure of the present invention is provided with fin 16 on the inwall of cylinder, fin is placed with a filter stand 15, is filled with porous filter material 10 in filter stand, be provided with handle 9 on filter stand.The present invention waters to crop with the negative pressure water supply device being vertically embedded in crop root zone in the system of a sealing, when watering, water in water source container or liquid manure solution are through suction hose, solenoid electric valve, gas collecting jar with ground-on cover plate, cartridge filter and outlet pipe, each tube connector flows into each negative pressure water supply device, because gas collecting jar with ground-on cover plate is higher than negative pressure water supply device, can be convenient to collect the gas overflowed, be full of water slowly to before system cloud gray model each negative pressure water supply device, discharge intrasystem air, just absorb water from negative pressure water supply device when soil is drier, gas collecting jar with ground-on cover plate middle water level is declined, pressure reduces, when being reduced to the lower limit of negative pressure pressure switch signal of setting, solenoid electric valve is opened, because atm difference water just flows into gas collecting jar with ground-on cover plate from water source container, along with entering of current, in gas collecting jar with ground-on cover plate, water level rises, pressure starts again to raise, when being elevated to the higher limit of setting, solenoid electric valve cuts out, the water entering gas collecting jar with ground-on cover plate through filter cylinder laggard enter negative pressure water supply device, in water, larger particles is filtered in filter cylinder, because water flow in pipeline is slow, little on the impact of filter, air contained in water during this just collects in an internal upper part, when cylinder internal gas pressure reaches the higher limit of negative pressure pressure switch signal, unnecessary air is extracted out through exhaust tube by air extractor, when gas collecting jar with ground-on cover plate internal gas pressure drops to the lower limit of negative pressure pressure switch signal, stopping of bleeding, so repeatedly, can make irrigation normally run.Reach purpose of design.
