Description

Ultrasound - aquaculture parasite removal system including microbubble system

The present invention relates to a plant parasiticidal removal system including an ultrasound-microbubble system, and more particularly, to an ultrasound-microbubble system capable of removing minute substances to be removed using ultrasonic waves and microbubbles, The present invention relates to a cleaning device including a cleaning device.

Ultrasonic wave means a sound having a frequency higher than an audible frequency (20 to 20,000 Hz), which is a frequency of a human audible sound, and a mechanical deformation occurs in which a piezoelectric material is expanded and contracted by applying a voltage, To generate ultrasonic waves.

These ultrasonic waves are vibration sound waves that attenuate in the air but propagate far away in water or oil. The higher the Hz is, the higher the bioabsorption rate is, and the lower frequency (1 MHz) penetrates deeply and the shape of the fetus and the medical image , Ultrasonic collapse, washing, etc., and high frequency (3 MHz) is used for skin care by surface penetration.

In particular, ultrasonic cleaning can generate ultrasonic waves of high frequency in water to remove microscopic dust and pesticide residues of fruits and vegetables by vibration of water molecules, and can be used for kitchen utensils such as tableware, cutlery, scissors, glasses, toothbrush, It has a merit that it can be washed in a short time to a place between the minute gaps where the inside is not visible or the hand can not reach, so that it is easily used for cleaning for skin care.

On the other hand, microbubbles are ultrafine bubbles which can not be recognized by eyes having a diameter of 10 to 50 μm or less, and are 1 / 2,000 of a normal bubble, which refers to fine air particles smaller than the skin pores (25 μm).

These microbubbles rise at a very slow rate of 0.1 cm / sec to the water surface due to low buoyancy, while normal bubbles rise in the water to rupture on the surface, but microbubbles generate energy before they rise to the surface, Ultrasound generation, high sound pressure of 140 db, instantaneous high heat generation of 4,000 ~ 6,000 ℃.

In addition, it has excellent skin regeneration and sterilization effect and is used in skin cleansing. It is utilized in various fields due to physical and chemical properties such as gas dissolving effect, magnetic pressure effect, and electrification effect.

This results in sterilization in the course of stabilization of the microbubble water, and it is possible to sterilize the pollutants by generating shock waves at a temperature of 4,000 ~ 6,000 ℃ and a pressure of 500 atm, at a moment of 1 millionth of a second, In addition, the amount of dissolved oxygen is increased by 40% compared to existing tap water, so that the adsorption cleaning effect of pollutants, vibration wave generation through bubble rupture, negative ion generation and hot spot are formed.

The micro-bubble generation method is a pressurization type dissolution apparatus, a pressurization dissolution type, and an upstream-revolution type. In general, the pressurization dissolution method is used. However, the pressurization dissolution method is used at the time of generation of a microbubble having a low flow rate and a high concentration. There is a problem in that a large and constant-sized bubble is not continuously generated. Recently, a pressure swirl method is widely used.

On the other hand, in the prior art relating to a cleaning device using ultrasonic waves or microbubbles, a publicly known utility model publication 1998-027960 (Aug. 5, 1998) discloses a technique relating to an ultrasonic dishwasher, 10-2008-0092750 (Oct. 16, 2008) discloses an oxygen micro bubble supplying device for bathtubs.

However, in the practical application of the conventional ultrasonic cleaning apparatus, there are problems such as temperature, dissolved gas, output, frequency, etc. that deteriorate the characteristics of the ultrasonic wave, and thus the cleaning effect is deteriorated.

On the other hand, fish farms, especially farmed salmon, feed on antibiotics, insecticides, and various carcinogens. Therefore, the content of mercury and heavy metals is high, so that the environmental hormone (PCB) is 7 times higher than that of natural wild salmon, The probability of water parasitism increases by more than 30 times, and as a result, there is a risk that salmon will be killed by sea lice.

As a method for removing parasites such as water and the like, removal by a chemotherapeutic agent should be avoided because it causes drug resistance, toxicity, and environmental pollution. Secondary pollution problem does not occur, and environmentally friendly and less toxic This is a situation that needs to be removed.

As a result, the Thermolicer developed by the Norwegian Veterinary Academy in partnership with the aquaculture has no damage to the fish body by the heat treatment method and can reduce the number of motility water by about 75% However, in recent years, the effect has been drastically decreasing to more than 10 hours. In addition, there is an inconvenience that it is necessary to confirm whether or not it is removed visually after the treatment, and the product which can replace the thermolicer has not been developed so far, and is being used continuously.

Accordingly, there is a continuing need to develop a cleaning device capable of improving the above problems and maximizing the cleaning effect of fish.

The main object of the present invention is to provide a cleaning device for aquaculture including an ultrasonic-microbubble system capable of removing parasites and fine substances to be removed and having excellent cleaning power.

According to one embodiment, the cleaning device can clean the fish by first irradiating ultrasonic waves and irradiating secondary microbubbles.

Also, according to one embodiment, the ultrasonic generator may use a low power high frequency.

In addition, according to one embodiment, the cleaning device may further include one or more suctions in the cleansing tube for sucking and removing parasites and micro-materials off fish.

Also, according to one embodiment, the cleansing tube of the cleaning device may have a diameter to allow passage of one to five fish.

According to an embodiment of the present invention, a funnel-shaped conical tube is further connected between the inlet and the washing tub connected to one side of the farm, a portion connected to the farm is formed larger than the diameter of the washing tub, May be formed to be equal to or smaller than the diameter of the tubular tube.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In general, the nomenclature used herein is well known and commonly used in the art.

Throughout this specification, when an element is referred to as " including " an element, it is understood that the element may include other elements as well, without departing from the other elements unless specifically stated otherwise.

The present invention relates to a cleaning device for generating ultrasonic waves and microbubbles inside a farm to clean fish stored in the farm. The cleaning device according to the present invention is characterized in that an inlet is formed at one side of the farm and an outlet is formed at the other side Three - way tube; At least one ultrasonic generator for generating ultrasonic waves into the tub; And at least one microbubble generator for generating a plurality of microbubbles in the tub, wherein the ultrasonic generator and the microbubble generator are sequentially formed from the inlet of the tub, - A cleaning device for aquaculture comprising a microbubble system.

1 is a conceptual view of a cleaning apparatus for aquaculture including a sound wave microbubble system according to an embodiment of the present invention. Referring to FIG. 1, an inlet 11 connected to one side of a farm 10, Shaped ultrasonic wave generating device 30 for generating ultrasonic waves inside the washing tub 20 and an ultrasonic wave generating device 30 for generating ultrasonic waves inside the washing tub 20, And at least one microbubble generator (40) for generating a plurality of microbubbles into the body cavity.

Further, in the cleaning device, the ultrasonic wave generator is located in front of the micro bubble generator with respect to the traveling direction of the fish in the cleaning pipe, so that the fishes to be cleaned are firstly irradiated with ultrasonic waves and irradiated with micro bubbles The fish can be washed.

Here, when the ultrasonic wave is irradiated first, the parasites outside the fish can be stunned and removed from the surface of the fish. After the ultrasonic irradiation, the parasites removed from the surface of the fish by stunning by the minute bubbles during the microbubble operation, It can be floated up and removed.

In addition, microbubbles can be generated at the same time in the primary ultrasonic irradiation position. At this time, the microbubbles can be operated at a point where the intensity of the ultrasonic waves after the primary ultrasonic wave irradiation is one fifth to one twentieth .

Therefore, when the fish is washed using the cleaning apparatus according to the present invention, the fish is first introduced into the washing tub 20, the ultrasonic wave is firstly irradiated using the ultrasonic generator 30, By generating microbubbles using the microbubble generator 40, the parasites 50, fine substances, and the like attached to the outside of the fish can be removed and removed.

Here, the fish may be preferably salmon, and the parasite is a species mainly parasitic to salmon, such as Lepeophtherius salmonis, Caligus regercresseyi, Caligus spp. But are not limited thereto.

Further, the cleaning device for aquaculture including the ultrasonic-microbubble system of the present invention is capable of cleaning within a short time to a place where the inside of the object to be washed is invisible, can easily remove bacteria and foreign matter, It has an effect that it can be cleaned eco-friendly even if it is not used.

On the other hand, ultrasonic cleaning is a basic principle in which a sound wave vibrates water several times a second several times to remove foreign substances attached to the surface of the object, and cavitation occurs in the ultrasonic waves.

When a strong ultrasonic wave is irradiated in the liquid, the ultrasonic wave becomes a pressure wave, and the compressive force (static pressure) and the inflating force (negative pressure) are repeatedly shown as shown in Fig. 3, and bubbles are generated centering on minute foreign substances in the liquid at the time of negative pressure, This bubble will disappear at the next compression cycle.

The process of removing the contamination by cavitation is shown in FIG. 4, and cavitation bubbles are exploded as shown in FIG. 3 (a) to make a gap between the pollutants, and bubbles penetrate into the gap as shown in (b) To remove contaminants.

On the other hand, the microbubbles have a self-pressurizing effect, and the self-pressurizing effect is a phenomenon in which the bubbles staying in the water rupture by themselves in the water when they are compressed and pressurized by the external pressure.

In a short time of one millionth of a second, the chain reaction of compression and rupture is repeated. This is because the surface tension inside the bubble having spherical interface is generated by the force of compressing the gas, and the shock wave including the ultrasonic wave at the bubble burst, (140 dB of sound waves), and when released into the air, the ambient air is anionized by the Leonard effect.

In addition, when the bubble ruptures due to the self-pressurizing effect, instantaneous high temperature of 4,000 ~ 6,000 ℃ and shock wave of about 500 atmospheric pressure are generated, and harmful microorganisms such as bacteria, Escherichia coli and fine eggs can be sterilized.

As described above, the ultrasonic cleaning is performed mainly by the cavitation phenomenon of the ultrasonic wave. When the energy of the ultrasonic wave propagates in the solution, the micro bubbles are generated and extinguished by the pressure of the ultrasonic wave. This shock wave has an effect that it can be washed in a short time to a place where the inside of the object to be washed contained in the liquid is not visible deeply.

In addition, since microbubbles have a small pore size and a large surface area, they can easily remove bacteria and foreign matter by holding negative charges, and can clean more than 95% of bacteria by irrespective of the surface state. Therefore, And the microbubbles have the effect of maximizing the washing power due to the synergistic effect of the self-pressurizing effect. Thus, a good washing effect can be obtained in a farm or the like.

The ultrasonic generator 30 and the micro bubble generator 40 may include at least one of the ultrasonic generator 30 and the

ultrasonic generator

30, 30 and the micro bubble generator 40 do not overlap with each other.

In addition, the cleaning device may further include one or more inhalers for sucking and removing parasites and micro-materials off fish, which can be examined in more detail in FIG.

FIG. 2 is a schematic diagram illustrating the cleaning process inside the washing tub of the aquaculture apparatus including the ultrasonic-microbubble system. As a result of the ultrasonic waves irradiated through the washing tub 20 while the fish are passing through the washing tub 20, The parasites or micro-substances are removed, and the removed parasites or micro-substances may be discharged through the inhaler 31 to the outside of the washing tub.

Next, the fish subjected to the first ultrasonic cleaning move through the washing tub, and the microbubbles irradiated by the second microbubble generator 40 are removed to remove parasites or minute substances remaining in the fish. At this time, Or the fine material may be discharged through the inhaler 41 out of the cleaning tube.

In addition, although the sizes of the tubules can pass through all types of fish, it is preferable that the size of the tubules is such that only one to five fish can pass at a time. In this case, by not passing a large amount of fish, Uniformity can be provided.

In addition, in the cleaning apparatus for aquaculture including the ultrasonic-microbubble system of the present invention, it is preferable that the ultrasonic wave generator uses a low-power high-frequency wave of 500 W or less.

Here, when a high output high frequency wave is used, it affects not only the object to be removed but also the object to be cleaned, which may cause problems in application due to high cost and low efficiency.

On the other hand, when low power high frequency is used, there is no negative influence on the morphological change and motion of the object to be cleaned, and it can be destroyed by causing morphological change of the object to be removed.

A conical tube in the form of a funnel is additionally connected between the inlet 11 connected to one side of the farm 10 and the washing tub 10 and a portion connected to the farm is connected to the washing tub 10 And the portion connected to the washing tub 10 may be formed to be equal to or smaller than the diameter of the washing tub 10.

That is, a conical tube in the form of a funnel may be inserted into the inlet 11, and the conical tube may be formed in such a manner that the size of the tube gradually decreases with folding into the washing tube 20 from the farm 10, Can be moved to the vasoconstrictor 20.

In addition, the inlet 11 may be provided with a suction device for smoothly moving the fish into the washing tub 20, and the transfer device may be any device capable of rapidly forming the flow rate from the farm to the washing tub Can be used.
