Description

Technical Field [0001] The present invention relates to a device and a method for manufacturing a nutrient solution for hydroponic cultivation,

TECHNICAL FIELD The present invention relates to a nutrient solution for cultivating a crop or a plant during hydroponic cultivation, and relates to an apparatus and a method for producing a nutrient solution for hydroponic cultivation, which is adapted to produce a nutrient solution having optimal growth conditions for growing crops or plants.

In general, the spread of production technology of environmentally friendly crops through hydroponic cultivation has recently been greatly expanded in Korea. In particular, the government (Rural Development Administration) has been able to cultivate clean ginseng high-speed production technology, which was developed in July of last year, as a hydroponic cultivation technology, It has been reported that the business is very high.

In addition, the hydroponic cultivation method using the nutrient solution is a method for cultivating a crop using a nutrient solution in which essential elements required for the growth of a crop (or a plant) are dissolved at an appropriate concentration according to the absorption rate thereof. It is a scientific farming technology that cultivates crops by artificially controlling the nutrient solution and medium conditions so that they can be cultivated.

Such hydroponic cultivation methods are used not only for small crops such as vegetables but also for cultivation of large crops such as flower crops and fruit trees.

Such hydroponic cultivation is carried out by providing a cultivation vessel in which crops are planted and a feeding device for continuously supplying the nutrient solution to the cultivation vessel. In addition, the hydroponic cultivation is additionally provided with an illuminating device and an air conditioning device for cultivating the environment so that the crop absorbs the nutrient solution and smooth the growth, and an auxiliary facility for sterilizing and disinfecting the nutrient solution.

In hydroponic cultivation, the amount of solar radiation, temperature, and humidity are basically important factors. However, most of the water used is ground water, so that the water contained in the water can be classified into electrical conductivity (or total soluble solid), pH, And the hardness component, etc., and in the composition of the nutrient solution, it causes salt and the like depending on water, and has a great influence on the concentration.

Here, the nutrients used for hydroponic cultivation were prepared so that the EC (Electrical Conductivity) of the nutrients and the nutrients that helped the standard growth of each crop were kept constant. In addition, this nutrient solution was prepared by mixing nitrogen and water-soluble phosphoric acid, water-soluble glycols, water-soluble gods and water-soluble calcium at a certain ratio and adding trace elements.

However, such a conventional nutrient solution for hydroponic cultivation usually has a low alkaline value because it is ground water as a solution, and is not suitable for growing a crop, and has a very low content of nitrogen, which is a necessary factor for growth.

This ensures that the nitrogen is continuously supplied, the supplied nitrogen is dissolved evenly in the nutrient solution, and the circulating nutrient solution and the supplied air bubbles touch the roots of the crop to shake and induce the exercise to sufficiently absorb the nutrients in the nutrient solution.

In addition, although the supply of nitrogen is continuously performed because various minerals are dissolved in the raw water, a trace amount of minerals may be added to the nutrient solution stored in the cultivation vessel 500, if necessary.

<Modifications>

Fig. 5 is a plan view showing a modified example for the circulation of the nutrient solution in the manufacturing apparatus of Fig. 1, and Fig. 6 is a sectional view taken along line A-A of Fig.

5 and 6, a water flow guide member 800 is provided at the edge of the cultivation vessel 500 to change the circulation direction of the nutrient solution by changing the arrangement of the water flow generator 600, and to assist the circulation of the nutrient solution 1 is different from the embodiment of Fig. Therefore, the same reference numerals will be assigned to the same components as those of the first embodiment, and a brief description thereof will be given below. The water flow generator 600 and the water flow guide member 800 will be mainly described.

The water flow generator 600 includes a circulation motor 610, a discharge pipe 630, and an inlet pipe 620.

5, a plurality of discharge holes 631 are formed in the longitudinal direction, and through the discharge holes 631, the nutrient solution is discharged through the discharge pipe 630, To be discharged from several places. As a result, the flow of the raw water is formed in the counterclockwise direction, which is formed in the longitudinal direction of the supply pipe 720 and below the stored raw water as shown in FIG.

The inlet pipe 620 is open at its end and is spaced apart from the outlet pipe 630 by a predetermined distance, and the raw water is introduced into the circulating motor 610 through the end.

<Method>

7 is a flowchart showing a method of producing a nutrient solution using the manufacturing apparatus of FIG. Hereinafter, for the sake of convenience, the raw water is introduced into the cultivation vessel 500 from the raw water storage tank 100, the state up to just before the crop is disposed after being circulated is expressed as raw water, and the state after the crop is placed is expressed as a nutrient solution. That is, a series of processes until a crop is placed is a process of converting raw water to nutrient solution.

First, the raw water is supplied to the fluid crusher 200 (S10). Raw water such as ground water, tap water, hydrogen water, or anion water stored in the raw water storage tank 100 is supplied to the fluid crusher 200. Of course, the supply of raw water and the supply per hour are controlled through motors, valves, and the like.

Next, raw water is pulverized in the fluid pulverizer 200 and converted into alkaline water having an increased amount of dissolved oxygen (S11). At this time, the raw water is finely pulverized while passing between the fixed blade 270 and the rotating blade 230. Also, the rotating blade 230 is converted into alkaline water whose dissolved oxygen amount is increased as the raw water is crushed while being compressed and relaxed through the axial reciprocating movement of the rotating flange 220 formed by opening and closing the outlet 251. In addition, the water temperature rises while being crushed, and the ammonia contained in the raw water is volatilized and removed.

Next, the magnetic flux is passed through the magnetizing device 300 to be converted into magnetized water (S12). The alkaline water with the increased dissolved oxygen amount is passed through the magnetizing device 300 to make it magnetized.

Next, in the pH adjustment tank 400, it is converted into weak alkaline water (S13). The alkaline water with the increased amount of dissolved oxygen with magnetization is converted into weak alkaline solution with pH of 7.5 ~ 8.5 by adding neutralizing agent.

Next, the raw water stored in the cultivation vessel 500 is circulated together with the air introduction (S14). The alkaline water with the increased amount of dissolved oxygen with magnetization is stored in the cultivation vessel 500 and the air is circulated through the air supply unit 700 and the water flow generator 600 while supplying air to the raw water. At this time, the air supplied from the blower 710 is continuously supplied to the raw water through the supply pipe 720, and the raw water introduced into the supply inflow pipe 620 by the circulation motor 610 is discharged to the discharge pipe 630, . The circulating raw water circulates smoothly by the partition wall 520 and the water flow guide member 800 mounted on the cultivation vessel 500.

The raw water is converted into nutrient solution through the above process.

Thereafter, even after the crop is placed in the cultivation vessel 500, the nutrient circulating by the water flow guide member 800 is directed to the root of the crop, In addition, allow sufficient absorption of nutrients through the roots.
