Description

Pipe for measuring waste liquid of nutrient solution cultivation {Pipe for measuring waste liquid of nutrient solution culture}

The present invention relates to a piping for measuring nutrient solution culture waste, and in particular, nutrient solution culture waste fluid that can easily and quickly measure the electrical conductivity (EC) and hydrogen ion concentration (pH) of the waste fluid flowing out to a drain through a bed on which crops are planted. It's about measuring piping.

In general, nutrient solution culture is a room in which crops are supported or fixed in a medium without soil by various methods, and crops are grown with a culture medium in which essential elements necessary for crop growth are dissolved in appropriate concentrations according to their absorption rates.

Such nutrient solution cultivation can increase productivity even in a small cultivation area, and with the development of technology, automated cultivation and year-round cultivation are possible, so many farms have installed / operated nutrient solution cultivation facilities in recent years.

In nutrient solution culture, crops are planted on an artificial medium installed on a bed, and culture medium is periodically supplied to the crops planted on the artificial medium. At this time, the waste liquid supplied to the crops and drained is discharged along the bottom surface of the bed through a drain hose provided at a drain port at one end of the bed and flows into a drain pipe buried underground.

In nutrient solution cultivation, the electrical conductivity (EC) and hydrogen ion concentration (pH) of the nutrient solution supplied to crops have a great influence on the growth, quantity and quality of crops. It is important to supply the culture medium to control the electrical conductivity (EC) and hydrogen ion concentration (pH) inside the medium.

Since the drainage meter (nutrient solution analysis device) that automatically measures the water quality of the waste liquid is expensive, it is difficult to install due to the cost. Methods for measuring electrical conductivity and hydrogen ion concentration are mainly adopted. However, when using this measurement method, it takes a considerable amount of time to collect the waste liquid flowing out of each bed in a farmhouse operating several beds, and when a long time elapses, hardening of the drain hose progresses, making it difficult to collect waste liquid. There is a problem that measurement cannot be performed due to missing the measurement timing.

We propose a piping for measuring the waste liquid of nutrient solution cultivation, characterized in that

The scope of the present invention is not limited to the embodiments described below, and can be variously modified and implemented by those skilled in the art within the scope of not departing from the technical gist of the present invention.

Hereinafter, a piping for measuring nutrient solution culture waste of the present invention will be described in detail with reference to FIGS. 1 to 10 attached.

As shown in FIGS. 1 to 6, the pipe (A) for measuring the waste liquid of nutrient solution cultivation according to the present invention includes a supply pipe 100, a discharge pipe 200, and a measurement pipe 300 connecting the supply pipe 100 and the discharge pipe 200. While including, the drainage hole 11 of the bed 10 in which the crops for nutrient solution cultivation are installed, and the drainage hole 11 installed underground or on the ground, a part toward the bed 10 from the ground near the drainage hole 11 By connecting the protruding drain pipe 20, it basically serves to send the waste liquid escaping through the drain hole 11 to the drain pipe 20. As shown in Figure 2, the bed 10 of the present invention is installed at a predetermined height from the ground, and it is assumed that one end at which the drain 11 is formed is installed lower than the other end. In addition, the waste liquid in the present invention refers to the nutrient solution supplied to and drained from the crops as well as the culture solution remaining after being supplied to the crops planted in the artificial medium of the bed 10.

The supply pipe 100 has one end connected to the drain 11 installed in the bed 10 and the other end connected to communicate with the measurement pipe 300. One end of the supply pipe 100 connected to the drain 11 is preferably formed in an expanded pipe shape having a larger diameter than the rest of the supply pipe 100 as shown in FIGS. 3 to 6 . Accordingly, since the drain 11 is connected to be inserted into one end of the supply pipe 100, it is preferable to prevent the waste liquid discharged from the drain 11 from flowing into the supply pipe 100 and from coming out.

And the supply pipe 100 includes a portion disposed vertically while including one end connected to the drain hole 11 . The other end of the vertically disposed portion of the supply pipe 100 may be connected in communication with the measurement pipe 300 as well as communicated with other parts of the bent supply pipe 100. For example, the supply pipe 100 has one end connected to the drain port 11 and a first supply pipe part 110 vertically connected, and one end connected to the first supply pipe part 110, as shown in FIGS. 3 to 6. It may include a second supply pipe part 120 disposed orthogonally to the first supply pipe part 110 while communicating with the other end and communicating with the measurement tube 300 at the other end. As in the above-described example, the supply pipe 100 may be formed to have a structure bent at least once, and considering that the waste liquid is collected near the other end of the supply pipe 100, the collected waste liquid is directed to the supply pipe 100. This is to prevent backflow.

The discharge pipe 200 has one end connected to the drain pipe 20 protruding from the ground toward the bed 10, and the other end connected to communicate with the measurement pipe 300. At this time, the other end of the discharge pipe 200 is connected to a position lower than the other end of the supply pipe 100 connected to the measurement pipe 300, so that the waste liquid introduced through the supply pipe 100 moves downward along the measurement pipe 300. After being introduced into the discharge pipe (200).

The discharge pipe 200 in the present invention is configured such that the waste liquid moved downward along the measurement pipe 300 is moved upward and then moved downward to be discharged through the drain pipe 20 . To this end, the discharge pipe 200 is formed to be bent at least twice. As a result, a space is formed in the discharge pipe 200 and the measurement pipe 300 in which the waste liquid is stagnant.

As a specific example, as shown in FIGS. 3 to 6 , the discharge pipe 200 has one end communicating with the measurement pipe 300 and disposed orthogonally to the flow of waste fluid in the portion of the measurement pipe 300 that communicates with the first one. While one end communicates with the discharge pipe part 210 and the other end of the first discharge pipe part 210, one end of the first discharge pipe part 210 is disposed upward in parallel with the flow of waste liquid in the portion of the measurement pipe 300 in communication With the second discharge pipe part 220, one end communicates with the other end of the second discharge pipe part 220 and the third discharge pipe part 230 arranged horizontally, one end communicates with the other end of the third discharge pipe part 230 Including the fourth discharge pipe portion 240 disposed vertically, it may be formed to achieve a structure bent three times.

As such, in the discharge pipe 200 including the first discharge pipe part 210 to the fourth discharge pipe part 240, a certain amount of waste liquid is always gathered up to a point corresponding to the height at which the other end of the supply pipe 100 is located while the waste liquid flows. achieve a state That is, for example, as shown in FIG. 8, when the other end of the first discharge pipe part 210 corresponds to the height at which the other end of the supply pipe 100 is located, the waste liquid is always collected in the first discharge pipe part 210. achieve In addition, the waste liquid is always collected between one end of the supply pipe 100 and one end of the first discharge pipe part 210 of the measurement pipe 300 .

And when the waste liquid continuously flows in through the supply pipe 100, the waste liquid collected between one end of the supply pipe 100 and one end of the first discharge pipe part 210 and in the first discharge pipe part 210 among the measurement pipes 300 , as shown in FIG. 8, a portion is replaced with newly introduced waste liquid, and after a portion moves upward through the first discharge pipe portion 210 and the second discharge pipe portion 220, the third discharge pipe portion 230 After passing through, it moves downward through the fourth discharge pipe part 240 and is discharged to the drain pipe 20.

One end of the discharge pipe 200 connected to the drain pipe 20 is preferably formed in an expanded pipe shape having a larger diameter than the rest of the discharge pipe 200, as shown in FIGS. 3 to 6 . Accordingly, the drain pipe 20 is connected to be inserted into one end of the discharge pipe 200, and the waste liquid discharged from the discharge pipe 200 cannot flow into the drain pipe 20 and is primarily prevented from coming out. can

In addition, a discharge induction path 241 may be provided at one end of the discharge pipe 200 so that the waste liquid discharged from the discharge pipe 200 can be completely introduced into the drain pipe 20 . For example, on the inside of the fourth discharge pipe part 240 vertically disposed while including one end of the discharge pipe 200, the upper side adjacent to the drain pipe 20 inserted inside while forming a funnel shape as shown in FIG. A discharge guideway 241 extending downward from the drain pipe 20 may be provided.

Since at least the lower portion of the discharge induction passage 241 is located within the drain pipe 20, the waste liquid discharged through one end of the discharge pipe 200 can be completely blocked from flowing out of the drain pipe 20. In addition, a discharge guide groove 242 in the form of a screw thread is recessed into the inner surface of the discharge guideway 241, so that a vortex is formed so that the waste liquid can be discharged more smoothly.

The measuring pipe 300 is configured such that the other end of the supply pipe 100 communicates with it and the other end of the discharge pipe 200 communicates with it at a lower position than the other end of the supply pipe 100 . The measurement pipe 300 is specifically, as shown in FIGS. 3 to 6, a stagnation pipe portion 310 connecting a point where the other end of the supply pipe 100 communicates with a point where the other end of the discharge pipe 200 communicates, It includes a measuring pipe part 320 formed upward from the stagnant pipe part 310.

A structure in which the other end of the discharge pipe 200 communicates with the other end of the supply pipe 100 is located lower than the communication end of the supply pipe 100, and the discharge pipe 200 includes a structure in which waste liquid can move upward, As shown in FIG. 8 , a certain amount of waste liquid is always collected in the pipe part 310 while the waste liquid flows. A simple measuring device 30 may be inserted into the measuring pipe 320 as shown in FIGS. 8 and 9 to measure the water quality of the waste liquid collected in the stagnant pipe 310 . At this time, the simple measuring device 30 means an instrument capable of measuring electrical conductivity (EC) or / and hydrogen ion concentration (pH) of the waste liquid. And the other end of the measuring tube 320, one end of which is in communication with one end of the stagnant tube 310, is formed open so that the simple measuring instrument 30 can be inserted. A stopper 321 may be coupled to the other end of the measuring pipe 320 to prevent the inflow of foreign substances through the other end of the measuring pipe 320 .

As a first embodiment, as shown in FIGS. 3 to 6, the stagnant pipe 310 is formed in a straight line shape and may be disposed inclined downward while forming an acute angle from the ground, and the measuring pipe 320 is the stagnant pipe 310 From one end of the stagnant tube portion 310 and the same angle may be formed extending upward. As a second embodiment, the stagnant pipe part 310 may be formed in an 'L' shape including a horizontal part and a vertical part, and the measuring pipe part 320 is in communication with a point of the horizontal part of the stagnant pipe part 310 and is horizontal It may be formed extending upward so as to be orthogonal to the portion.

In addition, the measurement pipe 300 may further include a stagnant waste fluid discharge pipe 330 capable of discharging the waste fluid collected in the stagnant fluid pipe 310 to the outside. The stagnant waste liquid discharge pipe 330, for example, is formed downward from the other end of the stagnant pipe 310 as shown in FIGS. It can be configured to be able to control the external discharge. Therefore, by closing the valve 331 to block a point of the stagnant waste liquid discharge pipe 330, the waste liquid can be collected in the stagnant pipe 310, and if necessary, as shown in FIG. 10, the valve 331 By opening the stagnant waste fluid discharge pipe 330 to communicate with the outside, the waste fluid collected in the stagnant fluid discharge pipe 310 can be discharged to the outside, thereby preventing foreign substances contained in the waste fluid from being deposited.

As described above, in the pipe (A) for measuring waste liquid in nutrient solution cultivation according to the present invention, the flow of waste liquid in the measurement tube 300 is changed upward by the discharge pipe 200 and then discharged to the drain pipe 20, so that the supply pipe 100 The waste liquid introduced through the stagnation tube 310 is always collected, and the simple measuring instrument 30 is inserted through the measuring tube 320 to measure the electrical conductivity (EC) of the waste liquid collected in the stagnant tube 310 and Since the hydrogen ion concentration (pH) can be measured easily, the time for measuring waste water quality can be remarkably shortened, and labor saving effect can be obtained.
