| titleOfInvention | Nutrient solution supply system having multiple mixing tanks |
| abstract | The present invention relates to a nutrient solution supply system having multiple mixing tanks, a raw water pump in which an accommodating space is formed inside, water supplied from the outside through a water pump is accommodated inside, and the water accommodated inside is formed by a metering pump In addition to being spaced apart from the raw water tank and the raw water tank, a plurality of spaces are formed inside each to accommodate a plurality of tanks, and C (carbon), O (oxygen), H (hydrogen) are provided on the inside of each of the raw water tanks. ), N (nitrogen), P (phosphorus), K (potassium), Ca (calcium), Mg (magnesium), S (sulfur), Fe (iron), Mn (manganese), Cu (copper), Zn (zinc) ), B (boron), Mo (molybdenum), Cl (chlorine), any one or two or more of the liquid ratio is provided with a selectively mixed liquid ratio, and the liquid ratio formed with different components in each acceptable space A plurality of liquid fertilizer tanks each accommodated therein, spaced apart from the liquid fertilizer tank, and provided with an accommodating space inside, an acid liquid tank in which an organic acid liquid is accommodated, and a plurality of liquid fertilizer tanks spaced apart from the raw water tank are provided inside, is provided with each accommodating space, inside each receiving water from a raw water tank and from a plurality of liquid fertilizer tanks, any two or more selected from among liquid fertilizers having different components, each supplied with an organic acid liquid from the acid liquid tank and mixed to form a nutrient solution with different components and concentrations, and optionally any one or two or more types from the group consisting of a bubble generator, a stirring device, and a heater for smooth mixing of water, liquid fertilizer, and organic acid solution on each inner side A plurality of mixing tanks, each connected to the mixing tank to receive the nutrient solution, each of which is formed by a metering pump to supply the nutrient solution inside the mixing tank to the outside or to recirculate the supplied nutrient solution to the inside of the mixing tank A pump, a pH sensor and an EC sensor respectively provided on a pipe to which the mixing tank and the nutrient solution pump are connected to measure the pH concentration of the nutrient solution and the inorganic nitrogen concentration of the nutrient solution, and the nutrient solution pump are connected to each other to receive the nutrient solution In addition, foreign substances contained in the nutrient solution A bag filter that is provided to filter and filters suspended substances having a particle size of more than 1 μm or polyamide, polyethylene, polypropylene, polyvinylidene fluoride, polysulfone, cellulose acetate, Teflon, alumina , zirconia and titania, a microfiltration membrane with a pore size of 1 μm or less is used, and the microfiltration membrane is made of titanium oxide, zinc oxide, tin oxide, tungsten oxide and cadmium sulfide. A plurality of filters formed by coating one or more photocatalysts selected from the group consisting of, and connected to the filters to receive a nutrient solution having different components and concentrations, respectively, is supplied to the inside, and the mutual growth state or variety is different inside each A plurality of beds in which any selected one of the crops is grown, a plurality of drainage tanks each connected to the beds to receive and collect drainage that the crops cannot absorb, and each of the drainage collection tanks receiving drainage from each and receiving it inside A plurality of drainage tanks, a UV sterilizer provided to receive the drainage from the drainage tank and sterilize the bacteria contained in the drainage, and each connected to the UV sterilizer to receive the sterilized drainage inside each In addition, each of a plurality of drainage material treatment tanks provided to supply drainage to the mixing tank, the raw water tank, the liquid fertilizer tank, the acid liquid tank, the mixing tank, the nutrient solution pump, the bed, the drainage tank, the drainage tank, the UV sterilizer, the drainage material A plurality of connection pipes respectively connected to the treatment tank and provided to flow a fluid inside, a plurality of valves respectively provided on the connection pipes and provided to control the fluid flowing inside each of the connection pipes; A control unit that is connected to a feed water pump, a raw water pump, a nutrient solution pump, a pH sensor, an EC sensor, a UV sterilizer, and a valve to receive a signal and control each operation, the liquid fertilizer tank, the acid solution tank, and the mixing tank , are provided on the drainage tank and the drainage ash processing tank, respectively, and transmit a signal to the control unit. A plurality of float valves for opening and closing the valve, a light quantity measuring sensor provided at the upper part spaced apart from the bed to transmit the measured light quantity to the control unit, and the concentration of inorganic ions in the mixed nutrient solution on the mixing tank An ion sensor for detecting the nutrient solution, a nitrate sensor for detecting the nitrogen component in the nutrient solution, a potassium sensor detecting the concentration of potassium component in the nutrient solution, and a temperature sensor for detecting the temperature of the mixed nutrient solution are installed. |
