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 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 adopts potter's clay material more, aperture is very small, if process bad filtration problem, very easily stop up, cause systemic breakdown, because the power of Negative pressure irrigation comes from the suction of soil, the loss of flood peak of filtration system has very big impact to irrigation system, and the filtration problem of therefore resolving Negative pressure irrigation has great significance to improving applying of Negative pressure irrigation.
Summary of the invention:
The object of this invention is to provide a kind of inherent filtration Negative pressure irrigation device that can effectively 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: water source container be attached with a gas collecting jar with ground-on cover plate, on the nozzle of gas collecting jar with ground-on cover plate bottom, with gasket seal and clamp connection, there is a cartridge filter, a side bottom at cartridge filter leads to an outlet pipe, outlet pipe outer end is parallel with many tube connectors, on each tube connector, be separately installed with at least two negative pressure water supply devices, between gas collecting jar with ground-on cover plate upside and water source container, be connected with suction hose, suction hose is provided with solenoid electric valve, on gas collecting jar with ground-on cover plate top cover, be separately installed with a negative pressure pressure switch and an exhaust tube.Cartridge structure is to be provided with fin on the inwall of cylinder, is placed with a filter stand on fin, is filled with porous filter material in filter stand, is provided with handle on filter stand.
The present invention is supplied to plant root the water lower than negative pressure water supply device by controlling the negative pressure of gas collecting jar with ground-on cover plate under the effect of atm difference, realizes the accurate control of soil moisture content is continued to supply water, and water-saving result is good, saving is artificial, is with a wide range of applications.
Accompanying drawing explanation:
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.
Embodiment:
Describe by reference to the accompanying drawings embodiment in detail, the present invention is the gas collecting jar with ground-on cover plate 6 that is attached with at water source container 1, on the nozzle of gas collecting jar with ground-on cover plate bottom, with gasket seal 8 and clip 7, be connected with a cartridge filter 11, a side bottom at cartridge filter leads to an outlet pipe 12, outlet pipe outer end is parallel with many tube connectors 13, on each tube connector, be separately installed with at least two negative pressure water supply devices 14, between gas collecting jar with ground-on cover plate upside and water source container, be connected with suction hose 2, suction hose is provided with solenoid electric valve 3, on gas collecting jar with ground-on cover plate top cover, be separately installed with a negative pressure pressure switch 4 and an exhaust tube 5.Cartridge structure of the present invention is on the inwall of cylinder, to be provided with fin 16, is placed with a filter stand 15 on fin, is filled with porous filter material 10 in filter stand, is provided with handle 9 on filter stand.The present invention waters to crop with the negative pressure water supply device that is vertically embedded in crop root zone in the system of a sealing, while 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 overflowing, be full of water slowly to before system operation each negative pressure water supply device, discharge intrasystem air, when soil is relatively drier, just from negative pressure water supply device, absorb water, 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, while being elevated to the higher limit of setting, solenoid electric valve cuts out, the water that enters gas collecting jar with ground-on cover plate enters negative pressure water supply device through filter cylinder is laggard, in water, larger particles is filtered in filter cylinder, because water flow in pipeline is slow, impact on filter is little, during this, in water, contained air just collects in an internal upper part, when cylinder internal gas pressure reaches the higher limit of negative pressure pressure switch signal, air extractor is extracted unnecessary air out through exhaust tube, when gas collecting jar with ground-on cover plate internal gas pressure drops to the lower limit of negative pressure pressure switch signal, bleed and stop, so repeatedly, can make to irrigate normal operation.Reach purpose of design.
