Description
Technical field
The utility model relates to a kind of cultivation apparatus without soil, particularly a kind of culture solution circulating device for soilless culture.
Background technology
The culture fluid of soilless culture need not arrhea moving to increase the root system mass exchange of being cultivated plant.At present, the EGR of known soilless culture culture fluid be adopt circulating pump with culture fluid from culture fluid feeder pump to the culture fluid supply side, so that culture fluid does not stop to circulate.The device of such soilless culture culture fluid circulation has following shortcoming: 1, and circulating pump need power or adopt internal combustion engine that energy is provided, the use cost height, and open-air power supply is not too convenient sometimes.2, the complex structure of circulating pump, cost cost height.
Summary of the invention
The purpose of this utility model is that the EGR that overcomes existing soilless culture culture fluid needs circulating pump, mechanism's complexity, the deficiency that use cost is high, the device that provides a kind of soilless culture culture fluid to circulate, the device of this soilless culture water circulation does not need circulating pump, and use cost is low.
The technical scheme that its technical problem that solves the utility model adopts is: culture solution circulating device for soilless culture, the culture tank that one bottom angled is arranged, its low side links to each other with accumulator tank by filter screen, be provided with the netted cultivation holder that parallels with the culture tank bottom in the culture tank, the sidewall of accumulator tank is provided with the culture fluid spacing hole, the bottom of accumulator tank is provided with the hole, the below in hole communicates with a high-end side of culture tank by recovery tube, the top in hole is provided with a nozzle, nozzle is connected with valve, and the valve other end is connected with the culture fluid supply pipe.
The hole of accumulator tank described in the utility model bottom is a funnel-form, leaves the gap between nozzle and hole, and the below, hole is connected by the high-end side of culture tank of recovery tube with netted cultivation holder below.
Nozzle described in the utility model is installed on the fixed mount that can regulate its height, and fixed mount is installed on the accumulator tank.
Culture fluid in the culture fluid supply pipe has enough pressure.Supply nozzle after culture fluid is by culture fluid supply pipe process valve regulated pressure, and from nozzle, spray at a high speed, culture fluid is punched in the hole of accumulator tank bottom under effect of inertia, in the hole, form certain pressure, culture fluid overcomes the resistance that gravity etc. forms under pressure, be transported to the higher end in culture tank bottom by recovery tube, under action of gravity, culture fluid flows through the culture tank inclined bottom, culture fluid is in flowing through culture tank below the netted cultivation holder in the process of tilting bottom, absorb because of volatilization with by Object of Development root system in the netted cultivation holder and to lose part, remaining culture liq flow into accumulator tank after by filter screen filtering solid sundries.Culture fluid flow velocity height between nozzle and the recovery tube, pressure is little, culture fluid flow velocity in the accumulator tank is low, the pressure height, therefore, culture fluid in the accumulator tank can be transported in the culture tank entering into recovery tube by the gap between nozzle and the hole recovery tube under the effect of pressure, thereby realizes circulating of culture fluid.Culture fluid unnecessary in the accumulator tank can be discharged from the culture fluid spacing hole.Control valve can be controlled the additional speed that realizes fresh medium, can control to adjust the circulation rate of culture fluid by the gap between fixed mount adjusting nozzle and hole recovery tube.
The beneficial effects of the utility model are, do not need circulating pump can realize circulating of culture fluid, invest little, save the energy, use cost is low, does not have mechanical fault, be convenient to safeguard, can be widely used in the culture fluid circulation of soilless cultures such as vegetables, and be suitable for the occasion of unregulated power supplies such as field.
Description of drawings
Fig. 1 is a vertical section structure schematic diagram of the present utility model.
Among the figure, culture tank 1 is cultivated holder 2, filter screen 3, accumulator tank 4, nozzle 5, fixed mount 6, valve 7, culture fluid supply pipe 8, gap 9, hole 10, recovery tube 11, culture fluid spacing hole 12.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further specified.
Referring to Fig. 1, culture solution circulating device for soilless culture of the present utility model, the culture tank 1 that one bottom angled is arranged, its low side links to each other with accumulator tank 4 by filter screen 3, be provided with the netted cultivation holder 2 that parallels with culture tank 1 bottom in the culture tank 1, the sidewall of accumulator tank 4 is provided with culture fluid spacing hole 12, the bottom of accumulator tank 4 is provided with hole 10, the below in hole 10 communicates with a high-end side of culture tank 1 by recovery tube 11, the top in hole 10 is provided with a nozzle 5, nozzle 5 is connected with valve 7, and valve 7 other ends are connected with culture fluid supply pipe 8.Culture fluid in the culture fluid supply pipe 8 has enough pressure.Supply nozzle 5 after culture fluid is regulated pressure by culture fluid supply pipe 8 through valve 7, and at a high speed from nozzle during 5 ejections, culture fluid is punched in the hole 10 of accumulator tank 1 bottom under effect of inertia, in hole 10, form certain pressure, culture fluid overcomes the resistance that gravity etc. forms under pressure, be transported to the higher end in culture tank 1 bottom by recovery tube 11, under action of gravity, culture fluid flows through culture tank 1 inclined bottom, culture fluid is in the process that flows through culture tank 1 tilting bottom, because of volatilization with cultivated in the holder 2 the Object of Development root system and absorb and lose part, remaining culture liq flow into accumulator tank 4 after by filter screen 3 filtering solid sundries.Culture tank 1 is rectangle or other shape of bottom angled, be provided with netted cultivation holder 2 in culture tank 1 inner bottom face near inclination, the card of netted cultivation holder 2 parallels with culture tank 1 bottom angled face, filter screen 3 is vertically set on the lower position of culture tank 1, and the opposite side of filter screen 3 is accumulator tank 4.The hole 10 of accumulator tank 4 bottoms is a funnel-form, the back cut diameter of its funnel is more than or equal to the diameter of nozzle 5 mouths, be convenient to make the nozzle 5 and 10 in the hole that are in the top to leave gap 9, culture fluid flow velocity height between nozzle 5 and the recovery tube 11, pressure is little, culture fluid flow velocity in the accumulator tank 4 is low, the pressure height, therefore, culture fluid in the accumulator tank 4 can enter into recovery tube 11 by the gap 9 between nozzle 4 and hole 10 recovery tubes 11 under the effect of pressure, be transported in the culture tank 1, thereby realize circulating of culture fluid.The openings of sizes of control valve 7 can be controlled the additional speed that realizes fresh medium, and culture fluid unnecessary in the accumulator tank 4 can be discharged from culture fluid spacing hole 12.10 belows, hole ask culture tank 1 a high-end side of 2 belows to be connected by recovery tube 11 and netted cultivation, make culture fluid ask 2 belows to flow through from netted cultivation, are convenient to realize under lower pressure circulating of culture fluid.For ease of the location and the adjusting of nozzle 5, nozzle 5 can be installed on the fixed mount 6 that can regulate its height, fixed mount 6 is installed on the accumulator tank 4.Regulate between nozzles 5 and hole 10 recovery tubes the circulation rate that 11 gap 9 can control to adjust culture fluid by fixed mount 6.
