The present invention relates to a pipe connection system used in the pond purification device for improving the water quality of the pond, more specifically, when supplying the gas (O₂, O₃) useful for water quality management with the chemical solution, is released as it is not mixed with water The present invention relates to a pipe connection system of a pond purifier, which reduces gas waste and prevents waste of gas and enables more effective water quality management of the pond.

Ponds are rich in algae nutrients, and if oxygen is not supplied enough to oxidize the nutrients, algae will thrive excessively and cause red tide, which leads to severe eutrophication. .

Accordingly, when the amount of dissolved oxygen decreases, turbidity increases, resulting in a vicious cycle of breeding, growth, and extinction of algae.

In addition, when there is no oxygen or a low anaerobic environment, anaerobic microorganisms generate hydrogen sulfide or methane gas, causing odors, especially in the absence of fluidity with ponds or reservoirs. As such, it is necessary to forcibly supply the pond with a gas (O2, O3, etc.) or a liquid (PH regulator, algae, photosynthetic blocker, flocculant, etc.) useful for water quality control.

1 is a plan view for explaining a pond purification apparatus used in the present invention, the pond purification apparatus is shown in Figures 1 to 3, the intake port 5 located in the deep portion of the pond (1), A suction pipe 3 connected between the intake port 5 and the pump P and a long connection along the pond edge line 2 to supply the chemical liquid supplied from the pump P evenly over the entire pond. An end portion is connected to a closed chemical liquid supply pipe 4, a plurality of nozzle connection pipes 9 branched inwardly at predetermined intervals from the chemical liquid supply pipe 4, and a tip of the nozzle connection pipe 9. The center is composed of a venturi nozzle (7) connected to the air intake pipe (6) which is in communication with the atmosphere.

That is, a plurality of nozzle connecting pipes 9 are branched to the chemical liquid supply pipe 4 at predetermined intervals, and each of the nozzle connecting pipes 9 ends is provided with an air suction pipe 6 exposed out of the water surface by a certain height. The venturi nozzle 7 is installed to supply oxygen in the air through the air suction pipe 6 to increase the amount of dissolved oxygen.

In addition, the present invention may include a chemical solution injection device 8 for separately supplying a microbial culture medium and a chemical solution (pond clarifier, etc.) useful for water quality control of the water returned to the pond along the chemical solution supply pipe (4), the chemical solution injection The device 8 is connected between the discharge port of the pump P and the chemical liquid supply pipe 4.

Since the intake port 5 absorbs the water of the pond and the venturi nozzle 7 discharges the chemical liquid, the fluid flow is formed as shown by the arrow (see FIG. 1).

On the other hand, since the chemical liquid supply pipe (4) is formed long along the pond edge line (2), the overall configuration is similar to the shape of the pond, the pump (P) is a venturi nozzle connected to the end of the chemical liquid supply pipe (4) Also in (7), it is to be designed to create a sufficient pressure to eject the chemical liquid.

In addition, the intake port 5 should be installed in the deep portion of the pond so that the water intake is easy by water pressure, and the nozzle connecting pipe 9 and the venturi nozzle 7 are air connected to the middle of the venturi nozzle 7. The tip of the suction pipe 6 is preferably installed in a relatively upper portion so as to be easily exposed to the atmosphere, and the outlet of the venturi nozzle 7 should be installed so as to face the center of the pond.

First, as shown in FIG. 4, when the nozzle connecting pipe 19 is connected higher than the chemical supply pipe 4, if only the liquid is mixed into the chemical solution, there is no problem, but as shown in the illustrated embodiment, the liquid 41 and the gas 42 are When mixed together and divided into upper and lower parts, the gas 42 is positioned on the nozzle connecting pipe 19 coupled with the venturi nozzle 7, and thus may be discharged as long as it is not dissolved in the chemical solution. Therefore, in this case, there is a problem that the waste of the gas is severe when the gas containing the gas useful for water quality management, such as O2, O3.

On the contrary, when the nozzle connecting pipe 19 'is connected lower than the chemical supply pipe 4 as shown in FIG. 5, the liquid 41 is combined with the venturinozzle 7 even when the liquid and gas are mixed together in the chemical solution. Since it is located toward the nozzle connecting pipe 19 ', the gas 42 cannot be discharged in a state in which it is not dissolved in the chemical liquid. Therefore, since the gas contained in the chemical liquid is not wasted, economical use is possible as compared with FIG. 4.

By the way, when connecting the pipe used in the pond purification device first arranges the chemical liquid supply pipe 4 along the pond edge line (2), and then a plurality of nozzle connecting pipes 19 are fixed to each other in the chemical liquid supply pipe (4) When the nozzle connector 19 'is positioned lower than the chemical supply pipe 4, as shown in FIG. 5, the nozzle connection 19 is connected to the lower side of the chemical supply pipe 4 as shown in FIG. There was a problem because the work is inconvenient and inefficient.

The present invention is to solve this problem, and when supplying the gas (O₂, O₃) useful for water quality management with the chemical solution, by reducing the amount of emissions released as it is not mixed with water to prevent the waste of the gas and water quality management of the pond It is an object of the present invention to provide a piping connection system of a pond purifier to make it more effective.

That is, in the present invention, the gas loss is minimized when gas is injected into the chemical liquid, and the gas and liquid can be supplied by one device, thereby greatly reducing the device installation cost and maintenance cost. will be.

In addition, in the present invention, by configuring the pipe connection system in consideration of the ease of operation, there is another object to make the work efficient without being inconvenient.

In order to achieve the above object, in the present invention, the nozzle connecting pipe is configured to connect to the upper portion of the chemical liquid supply pipe, but the nozzle connecting pipe is extended from the connecting portion to the inside of the chemical liquid supply pipe so that it is always located in the liquid inside the chemical liquid supply pipe. This ensures that the gas cannot escape out of the venturi nozzle through the nozzle connection without dissolving the gas in the liquid.
