Description

양액재배용 양액 자동 공급장치{Nutrient automatic feeding device for nutrient solution cultivation}Technical Field [0001] The present invention relates to a nutrient solution feeding apparatus for nutrient solution cultivation,

본 고안은 토양 없이 배양액만으로 식물을 재배하는 양액재배에 있어서 양액을 적절하게 혼합하여 자동으로 공급하는 양액 공급장치에 관한 것으로, 좀 더 구체적으로는 액비와 액산을 각각 개별적으로 콘트롤 되는 인버터제어 소형 고압펌프를 통하여 공급토록 함으로써 정밀하고 균일한 혼합 및 양액 공급장치 구성을 간단화 할 수 있도록 개선한 것이다.The present invention relates to a nutrient solution feeding apparatus for automatically feeding a nutrient solution mixed with a nutrient solution in a nutrient solution cultivation in which a plant is cultivated without a soil and more specifically, Pump to provide a precise and uniform mixing and simplification of nutrient supply configuration.

주지된 바와 같이 양액재배(養液栽培)는 토양을 이용하지 않는 재배 방법으로 생육에 필요한 영양 성분을 적절하게 흡수할 수 있도록 알맞은 농도로 조절된 배양액에 식물을 심어 산소를 공급해 주며 재배하는 방법을 말하는 것으로, 물만으로 재배하기 때문에 ‘수경 재배(水耕栽培)' 또는 ‘용액 재배(Solution Culture)’라고도 한다. 대체로 오이, 토마토, 방울토마토, 고추, 상추, 미나리, 장미, 카네이션 등을 재배하는데 이용되는 방법이다.As is well known, nutrient cultivation is a cultivation method that does not use the soil. It is a method of cultivating the plant by planting it in the culture medium adjusted to the proper concentration so that the nutrient component necessary for growth can be suitably absorbed. It is also said to be called 'hydroponics' or 'solution cultivation' because it is cultivated only by water. It is generally used to grow cucumbers, tomatoes, tomatoes, peppers, lettuce, buttercups, roses, carnations and the like.

이러한 양액재배는 단기간에 많은 양의 작물을 수확할 수 있고 토양재배와 비교하여 자연환경의 지배를 훨씬 덜 받기 때문에 농경이 불가능한 곳에서도 재배가 가능한 장점이 있으나, 작물에 대한 세심한 영양관리가 필요하다.This nutrient solution cultivation can harvest a large amount of crops in a short period of time and is much less subject to natural environment than soil cultivation, so it is possible to cultivate even in places where farming is impossible, but careful nutrition management of crops is necessary .

양액재배에 사용되는 양액은 통상 자동공급장치를 이용하여 공급하고 있는데, 일반적으로 2~3개 정도의 액비탱크에 액상비료가 준비되고 1개의 액산탱크에는 산도(ph)를 조절하기 위한 액산이 준비되며, 이를 펌프를 통해 공급되는 원수(原水)에 혼합되도록 하는 구성이다.Nutrient solution used for nutrient solution cultivation is usually supplied by automatic feeding device. In general, two to three liquid tanks are prepared with liquid fertilizer, and one liquid tank is provided with liquid acid for adjusting pH And is mixed with the raw water supplied through the pump.

상기 액비와 액산을 원수에 혼합하는 종래의 구성을 살펴보면, 원수펌프를 이용하여 원수를 혼합통에 공급하고 별도의 혼합펌프를 구성하여 혼합통 내의 원수를 다시 혼합통에 순환시키는 과정의 관로에 벤츄리관을 연결하여 액비와 액산을 혼합통에 공급하는 것으로, 이러한 방식의 공급은 원수의 순환에 의해 액비와 액산이 벤츄리 원리에 의해 빨려들어가는 방식이고 제어는 솔레노이드 밸브의 ON/OFF에 의존하므로 액비와 액산의 공급정도를 정확히 조절하는 것이 어려우면서 혼합 또한 충분하고 신속하게 이루어지지 않는 단점이 있었다.In the conventional structure in which the liquid and the liquid are mixed in the raw water, raw water is supplied to the mixing cylinder using a raw water pump and a separate mixing pump is used to circulate the raw water in the mixing cylinder back to the mixing cylinder. The supply of liquid and liquid is supplied to the mixing cylinder by connecting the pipes. The supply of this type is sucked by the venturi principle of the liquid and the liquid by the circulation of the raw water. Since the control depends on the ON / OFF of the solenoid valve, It is difficult to precisely control the supply amount of the liquid acid, and the mixing is also insufficient and can not be performed quickly.

또한 종래의 공급방식에 의하면 원수에 액비와 액산이 공급된 후 적절한 혼합량과 산도를 맞추기 위하여 별도의 혼합탱크를 구비하였어야하며, 원수를 혼합탱크에 공급하는 원수펌프와 양액을 혼합시키기 위한 혼합펌프 그리고 혼합탱크의 양액을 재배시설에 공급하는 공급펌프 등 3개의 펌프를 설치하여야 하므로 구성이 복잡해지고 양액 자동 공급장치의 제조시간과 제조비용이 많이 소요되는 단점이 있었다.In addition, according to the conventional feeding method, a separate mixing tank should be provided to suit the mixing amount and acidity after the liquid and liquid acid are supplied to the raw water, and a raw water pump for supplying the raw water to the mixing tank and a mixing pump for mixing the nutrient solution, It is necessary to install three pumps such as a feed pump for supplying the nutrient solution of the mixed tank to the cultivation facility, which complicates the construction and requires a lot of manufacturing time and manufacturing cost of the nutrient solution supply device.

이러한 본 고안에 의하면, 인버터 제어방식의 소형 고압펌프를 이용하여 액비와 액산을 각각 직접 원수에 혼합시켜 곧바로 재배시설에 공급가능토록 구성함으로써 소요되는 펌프의 숫자가 줄고 라인이 단순화되는 등 간단한 구성과 저렴한 제조비용으로 양액기의 제공이 가능하도록 되며, 아울러 정확한 공급량의 제어가 가능함에 의해 양액재배 식물의 품질과 생산성을 향상시키게 되는 유용한 고안이라 할 수 있다.According to the present invention, it is possible to mix the liquid and the liquid directly with the raw water by using the small-sized high-pressure pump of the inverter-controlled system, and to supply the liquid and the liquid directly to the cultivation facility. It is possible to provide a fluid machine with a low manufacturing cost and to control the amount of supply accurately, which is a useful tool for improving the quality and productivity of a nursery plant.

The liquid and the liquid are supplied from the liquid tanks 20 and 20 ' And a small-sized high-pressure pump (24) are provided in a connection pipe (22) connected to the high-pressure pump (12). The small high-pressure pump 24 is capable of inverter control.

상기 액비와 액산을 공급하는 위치 이후의 공급라인(12)에는 액비와 액산이 좀더 균일하게 혼합되도록 혼합통(14)을 설치한 후, 농도센서(15)와 산도센서(16)를 설치하여 액비의 농도와 산도를 측정할 수 있도록 구성한 다음 재배시설(30)로 연결되도록 한 것이다.A mixing cylinder 14 is installed in the supply line 12 after the position where the liquid and the liquid are supplied so that the liquid and the liquid acid are more uniformly mixed. Thereafter, the concentration sensor 15 and the acidity sensor 16 are provided, And then connected to the cultivation facility 30.

본 고안의 양액 공급장치를 컨트롤하는 제어부(1)는 온도, 습도, 식물의 생장 정도 등의 외부 조건을 양액 공급 정도와 농도 등에 적용하고, 입력부(2)를 통하여 공급되는 양액의 혼합비율, 산도 등을 설정하면, 이를 원수를 공급하는 공급펌프(10)와 액비 및 액산을 공급하는 소형 고압펌프(24)를 통하여 제어할 수 있도록 하며, 이러한 과정에서 농도센서(15)와 산도센서(16)의 감지 정도를 감안하여 추가적으로 공급펌프(10)와 소형 고압펌프(24)의 작동을 제어하여 공급량을 조절토록 하는 것이다.The control unit 1 for controlling the nutrient solution supply device of the present invention applies external conditions such as temperature, humidity, and plant growth degree to the nutrient solution supply level and concentration, and controls the mixing ratio of the nutrient solution supplied through the input unit 2, The concentration sensor 15 and the pH sensor 16 can be controlled by the feed pump 10 for supplying raw water and the small high pressure pump 24 for supplying liquid and liquid, The operation of the supply pump 10 and the small high-pressure pump 24 is controlled in order to control the supply amount.

이와 같이 구성되는 본 고안의 작용을 살펴보면 다음과 같다.Hereinafter, the operation of the present invention will be described.

액비탱크(20)(20')와 액산탱크(21)에 각각 액비와 액산을 투입하고 작동을 시작하는데, 작동 전 입력부(2)를 통하여 작물의 종류나 기타 여건에 따르는 공급조건을 제어부(1)에 설정하며, 공급펌프(10)를 작동시키면 원수흡입관(11)을 통하여 원수가 공급펌프(10)를 통하여 공급라인(12)으로 공급된다.The liquid level and the liquid acid are supplied to the liquid tank 20 (20 ') and the liquid liquid tank 21, respectively, and operation is started. The supply condition according to the kind of the crop and other conditions is inputted through the input unit (2) When the feed pump 10 is operated, the raw water is supplied to the feed line 12 through the feed pump 10 through the raw water suction pipe 11.

이러한 과정에서 액비와 액산의 공급작용이 동시에 이루어지는데, 제어부(1)의 설정과 작동 신호에 의하여 소형 고압펌프(24)를 작동시켜 연결관(22)을 통해 액비와 액산을 공급하게 된다. 이러한 과정에서 소형 고압펌프(24)는 인버터제어가 가능하므로 필요에 따라 공급량을 제어할 수 있으므로 항상 필요한 만큼의 액산과 액비를 정확하게 조절하면서 공급할 수 있는 것이다. 순간유량계(23)는 시각적으로 액비와 액산의 공급상태를 확인할 수 있게 해준다.In this process, the operation of supplying the liquid and the liquid is performed at the same time. The small high-pressure pump 24 is operated by the setting and operation signal of the control unit 1 to supply the liquid and the liquid through the connection pipe 22. In this process, the small high-pressure pump 24 can control the inverter so that the supply amount can be controlled according to the need, so that the liquid acid and liquid ratio can be always adjusted while being precisely controlled. The instantaneous flow meter 23 allows visually checking the supply status of the liquid and liquid.

상기 공급에 의해 액비와 액산이 원수에 혼합된 상태에서 혼합통(14)을 거치면서 한번 더 균일하게 액비와 액산이 혼합되고, 혼합된 양액이 곧바로 재배시설(30)로 공급되는 것이며, 공급 직전에 농도센서(15)와 산도센서(16)에 의해 액비의 농도와 산도를 측정하여 상기 측정데이터에 의해 정상적인 범위 내에 농도와 산도가 측정되지 아니하면, 제어부(1)가 소형 고압펌프(24)에 신호를 보내 공급량을 조절하도록 작동하는 것이다.The liquid and the liquid acid are once more uniformly mixed through the mixing cylinder 14 while the liquid and the liquid acid are mixed with the raw water by the supply and the mixed nutrient solution is immediately fed to the cultivation facility 30, The control unit 1 measures the concentration and the acidity of the liquid slurry by the concentration sensor 15 and the acidity sensor 16 and measures the concentration and acidity of the liquid slurry in the small high- To adjust the supply amount.
