BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nozzle for generating vortex,

The present invention relates to a nozzle for vortex formation, and more particularly, to a vortex nozzle for vortex formation, in which at least one water-jet nozzle having a different diameter is provided in a water tank to form a vortex in the center of a water tank to circulate or stir the water, And an object of the present invention is to provide a nozzle for water retention for forming a vortex so that organic matter in the water tank can be rotated and removed.

In general, aquaculture by seawater can be broadly divided into a marine aquarium and a marine cage. The marine aquaculture is a method of transferring a target organism to an aquarium so that the habitat is artificially controlled. It is easy to exchange seawater and water treatment and mass production, but it is greatly affected by environmental change.

On-shore aquaculture is a way to protect aquatic life from environmental changes and form a suitable environment for aquaculture by installing water tanks on the land to fill aquaculture water and then raising aquatic creatures in aquarium so that they can produce aquatic life safely and effectively. have.

Breeding water used in conventional aquaculture tanks is collected from seawater through the main pipe and fed into the farm. The breeding water supplied to the water tank is supplied to each tank with the main pipe extending to the inside of the farm and supplied to the water tanks, and a discharge hole in the form of a through hole is formed on either the bottom surface of the water tank or the water tank, So that the cleanliness of the aquaculture water stored in the water tank can be maintained.

However, in the case of onshore farms, organic pollutants such as excreta and feed residue accumulate in aquaculture tank, unlike the sea cage farms, because they are limited in the aquarium space and the yield. In the aquaculture farm, if the ammonia or other pollutants accumulated on the floor are artificially removed or not returned to clean water, the quality of the farm water will deteriorate with time.

In addition, when a large amount of fish is stored at a high density compared to the area of the aquaculture tank, the dissolved oxygen contained in the aquaculture water is rapidly consumed, and at the same time, various floating matters, proteins, ammonia and nitrogen Can accumulate at a high concentration in a short time.

When the water quality deteriorates, ammonia or hydrogen sulfide is generated in the summer when the water temperature is high, and not only the bad odor is generated but also viruses and pathogenic microorganisms are proliferated and the lethal amount is increased. Antibiotics may be added to farms to increase viral resistance, but the aquatic products to which antibiotics are administered can cause harm to human health due to residual antibiotic problems.

In order to maintain the water quality of the breeding water at a certain level, it is frequently changed to fresh seawater in the nearby sea, or the filter material such as gravel, sand, or sponge is laid on the bottom of the fish tank and the breeding water is filtered for a certain period. There is a way to use it again.

However, the supply of fresh breeding water can not be applied in the inland region, which is far from the coastal area, because of the heavy transportation cost and labor cost due to the transportation of seawater. Not only is the ability to purify by the filter medium very low, but also various bacteria can be generated in the process of protein and floating matter being accumulated in the filter medium and being corrupted, and it is very troublesome to take out and clean the filter medium.

In order to solve such a problem, a device such as a rotating impeller is installed according to the operation of a motor to generate an aeration by stirring the water for breeding, or by installing a breeze to increase the amount of dissolved oxygen in the water for breeding, Stirring and rotating the water tank, the feed residue or contaminants gathered on the bottom of the water tank are flowed without stagnation, thereby making it possible to maintain constant water quality without spoiling the water inside the water tank.

The above devices are a method of dropping the breeding water in a water tank and discharging congested pollutants by taking the circulation power of the breeding water by the force of falling water of breeding water. It is a problem that the pollutant can not be efficiently discharged .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a specific configuration of a vortex spraying nozzle according to the present invention will be described in detail with reference to the accompanying drawings.

1 shows a perspective view of a water tank equipped with a spray nozzle for vortex formation according to the present invention. The vortex spraying nozzle of the present invention comprises a water tank (10) having a bottom portion and a water tank outer wall having a predetermined height; At least one injection pipe is formed in the injection pipe 40 in the vertical direction in the injection pipe 40 which is provided at the inner side wall of the water tank of the water tank and has the injection pipe of a predetermined diameter in the downward direction of the water tank. A fine regulating pipe 20 provided on the injection pipe and a fine regulating valve formed on the fine regulating pipe.

The water tank 10 is integrally connected to the outer wall of the water tank, and is installed in such a manner that the upper part of the water tank is opened. It is possible to feed the breeding water through the water tank opening and to stock the fish inside the water tank. The water tank is made of fiber-reinforced plastic (FRP), polypropylene (PP), etc. It is most preferable to use a material that does not cause corrosion, and it has durability that can withstand water pressure when feeding water. Do.

A breeding water supply unit (90) is provided in the upper opening of the water tank to supply clean water to the inside of the water tank. The bottom portion of the water tank is formed of a circular or polygonal shape having a predetermined area and a drain is formed at the bottom of the water tank. The injection pipe 40 is installed in the water tank through the upper opening in the form of a straight pipe in the vertical direction on the inner side wall of the water tank. The injection pipe is connected vertically with an air pressurizing unit 50 installed outside and a breeding water supply pipe, and is introduced into the water tank and formed in the injection pipe, and is installed vertically with different nozzle diameters.

A fine regulating pipe (20) and a fine regulating valve are formed in the upper part of the injection pipe so that a certain amount of feeding water flows into the water tub while the feeding water and air are mixed into the injection pipe and supplied to the injection pipe. Since the fine regulating pipe 20 located on the injection pipe and the fine regulating valve formed on the fine regulating pipe are immersed in the water inside the water tank and it is not known whether the water is supplied, It is used as an effect.

Therefore, it is necessary to control the amount of water flow with the fine regulating valve so that a certain amount of breeding water flows through the fine regulating pipe according to the water pressure and the air pressure which the injection pipe receives.

One of the openings of the injection pipe can be connected to the pressurizing portion. The pressurizing portion not only feeds the air to the injection pipe but also injects the breeding water through the injection pipe at a proper water pressure, thereby circulating the water in the water tank.

The spray tube has a first spray tube in the downward direction at the upper part of the water tank, a second spray tube at the middle part, and a third spray tube at the lower part in order, and the diameter of the spray tube gradually decreases .

In other words, when the same air pressure is supplied to the spray pipe together with the feeding water, the pressure difference is generated according to the nozzle diameter of the spray pipe as the feeding water and the air pressure discharged through the spray pipe fall down to the vertical lower portion. The smaller it is, the faster the flow.

In the spray tube formed with nozzle diameters of different sizes depending on the height, the amount of water and pressure of the water sprayed from each spray tube are different. In the first spray tube having the largest diameter, a large amount of water is discharged in a certain direction at a slow speed, The smaller the nozzle diameter and the smaller the diameter of the nozzle, the less the discharge amount of the circulating water, the higher the pressure, and the faster the water flow is formed in the lower part where the nozzle diameter is relatively small.

Therefore, as the water pressure decreases from the lower part of the spray pipe to the upper part, the swirl water that rotates at the lower speed from the lower part causes vortex in the water tank as it goes up to the upper part, and the vortex causes the debris, And can be discharged with high efficiency in a short period of time.

The spray pipe connected to the pressurizing portion adjusts the rotational speed of the vortex for discharging the debris by adjusting the air pressure and the water pressure according to the amount of the debris accumulated in the water tank. In addition, it is appropriate to install the ejector apparatus by the ejector apparatus. When it is installed by the ejector apparatus, ambient air is sucked into the spray pipe when spraying the water in the water tank and sprayed into the water tank, The oxygen amount can be homogenized. Therefore, it is possible to replace various devices and structures used for supplying dissolved oxygen, thereby eliminating complicated structure obstacles such as an oxygen supplier installed in a water tank.

As the breeding water is stirred and rotated, feed residue or contaminants collected on the bottom of the water tank are not stagnated and rotate in a certain direction, so that the water in the breeding water can be kept constant without decaying.

FIG. 2 is a perspective view of a spray tube of a spray nozzle for vortex formation according to the present invention. FIG. The nozzle body of the high-pressure spray nozzle constitutes the entire frame of the nozzle, and the jet part, the oxygen supply part, and the breeding water supply part are fixed to supply oxygen, breeding water or the like to the water tank or supply high-pressure air.

An appropriate amount of oxygen and feed water controlled by an external spray controller is transferred to the oxygen supply unit and the breeding water supply unit through the oxygen supply pipe and the breeding water supply pipe, respectively.

The oxygen supply unit 80 should be connected to the compressor so as to receive the oxygen supply pipe 81 and to correspond to the diameter and supply the high pressure air to the connection unit. The breeding water supply unit 90 has a diameter that can correspond to the breeding water supply pipe 91. A filter member having a predetermined diameter for mounting and separating the breeding water supply pipe is provided in the opening corresponding to the breeding water supply unit, The foreign matter mixed with the water can be filtered before it is moved to the connection part.

The breeding water and the nutrients that have moved from the breeding water supply part to the connection part are mixed with the high pressure air supplied from the oxygen supply part and moved to the jet part 70 so that the breeding water of the controlled pressure can be injected into the water tank.

Fig. 3 shows the splitting portion of the spray nozzle of the spray nozzle for vortex formation of the present invention. The jetting section 70 may have a hollow structure such as a pipe, and may have a structure in which an opening corresponding to the connection portion and a hole having a through-hole shape serving as a passage through which the oxygen moved from the connection portion and the feeding water are injected into the water tank are formed.

The injection opening portion and the connection portion corresponding to the connection portion may be provided with threads on the corresponding portions so as to be fixed by a principle such as a bolt and a nut, but the method is not limited thereto. In addition, the rubber packing is inserted in the corresponding part of the jetting part and the connecting part, so that the breeding water and the air can be prevented from leaking.

In the jetting unit 70, a moving pipe 71 through which the feed water and nutrients can move can be installed at the connecting part, and a plurality of through holes can be formed in the moving pipe from the connecting part to the jetting part. Rubber packing is provided on the outer side of the moving pipe to increase the fixing force of the moving part and the inside of the jetting part, and air and the breeding water can be prevented from leaking to the moving pipe from the connecting part.

Figure 4 shows a perspective view of a water tank equipped with a modified dispensing nozzle for the vortex formation of the present invention and Figure 5 shows a perspective view of a modified dispensing nozzle for the vortex formation of the present invention. 4 to 5, when the injection angle of the spray tube is changed by installing the spray tube holder on one side where the spray tube is installed, the position of the spray angle is changed when the high-pressure water is sprayed And the fixation force capable of maintaining the injection angle can be increased.

The nozzle body is provided with three protruding openings composed of an oxygen supply corresponding portion, a breeding water supply corresponding portion, and a jetting portion corresponding portion, and a fixing device is provided inside the component corresponding to the outside of the opening, It can be facilitated.

Figure 6 illustrates the principle of vortex formation of the dispensing nozzle for vortex formation of the present invention. The injection angle of the spray tube can be easily adjusted. When supplying the breeding water to the water tank, it is appropriate to adjust the spraying angle in the direction of the spraying pipe and in the straight direction, and to adjust the spraying angle of the spraying pipe in the range of 0 to 60 ° Do.

The spraying pipe connected to the pressurizing portion can regulate the rotating speed by adjusting the air pressure according to the concentration of the residue in the breeding tank. As the feeding water is stirred and rotated, feed residue or contaminants collected on the bottom of the water tank are not stagnated and rotate in a certain direction, so that the feeding water in the feeding water can be kept constant without being decayed.
