Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention provides a work boat that sterilizes, sterilizes, and cleans pathogens, germs, dirt, etc. that are parasitic or attached to seaweed fronds during cultivation;
Regarding processing method.

(Prior Art) Conventionally, operations such as exterminating pathogenic bacteria and cleaning dirt from seaweed fronds grown in aquaculture nets set on the ocean are performed as follows.

(Al) The many thin lobes fixed on the lobes between the buoys, or the nets placed between the poles set up on the seabed in shallow waters, are untied and placed on a work boat, which is then placed in a container filled with processing liquid. It is manually hoisted into the sea, and after a certain period of time has elapsed, it is set on the sea surface again.

Cb) Pass a work boat carrying a container containing a treatment liquid thick enough to cause a pollution problem to pass under the set net, allowing the net to bend under its own weight, or use a cylindrical The treatment is carried out by rolling a weight onto a net and pressing it down to infiltrate the seeds.

(Problems to be solved by the invention) These processing operations had the following problems (al.
In the cold winter at sea, the work of untying and retying thin robes tied to buoys or poles is hard work for the hands.

(b) Moving unsteadily through a heavy net covered with seaweed,
In order to increase the effectiveness of the process, the nets were hoisted up by hand and immersed in the processing solution, and the net was manually moved from side to side, up and down, causing injuries to the arms, shoulders and lower back, and even the risk of falling.

(C) Conventional treatment methods utilize only the chemical and pharmacological effects of the treatment solution, and the net and seaweed fronds coated with a thick treatment solution are re-strung on the sea surface, so that the attached treatment solution is removed. Because they spill out into the ocean and cause damage to other living things, such as fish and shellfish, there is a strong need to develop a method to exterminate and clean them using as dilute a treatment solution as possible.

(d) Even if you use a net with thick seaweed leaves to seed the liquid in a small container, the liquid will be caught between the overlapping nets and leaves, and the treated liquid will be distributed evenly on the front and back of all the leaves. could not be applied.

(el) This work needs to be done quickly during the ebb and flow of the tide, and there is a need to shorten the work time and streamline it.

(Means for solving problems) In order to solve many of these problems, this invention (2)
Specifically, (1)
(3) At the bottom of the container, there is a (4) air diffuser made of a porous material with countless minute holes in ceramic, plastic, metal, sheet, film, etc.

This air diffuser is cylindrical or rectangular and hollow.

(3) The container is shaped like a boat in the sky, and (1) the container is loaded by crossing the edge of the container onto the same boat of the work boat.

(10) Penetrate the side wall or bottom plate near the bottom of the container by means of a fitting, and (4) connect an air pipe to the air diffuser. supplying.

(3) The container is filled with (2) the treatment liquid, and (4) air is blown out from the air diffuser.

The work boat equipped with the above-mentioned equipment is the work boat of the first embodiment (Fig. 1) described in claim 1, but the work boat of the second embodiment described in claim 2 is Boat (Figure 2)
(7) The device that supplies air is not an engine-driven blower, but an air cylinder.

An embodiment according to claim 3 is shown in FIG. 3 as a third embodiment.

In the third embodiment, (3) the inner surface of the container is covered with (8) a reflective material made of a hard material such as a metal plate, a ceramic plate, or an enamel plate.

The work boat, air diffuser, and air supply device are the same as those in the first embodiment or the second embodiment.

(effect) To use the device according to the invention, proceed as follows.

FIG. 4 shows a working method according to claim 4 of the present invention as a fourth embodiment.

(3) Fill the container with (2) the processing liquid and supply air from an air supply device such as a (5) blower or (7) air cylinder.
4) When the air diffuser is sent and ejected from countless microscopic pores,
The air turns into fine bubbles and causes the processing liquid to rise, stir, and flow.

When the bubbles disappear, ultrasonic waves, which are coarse waves, are generated and travel through the processing liquid.

This convection-like upwelling and stirring treatment liquid was placed on top (1
) A processing method in which the work boat passes under (9) the aquaculture net, bending the net, and soaking the seeds in the solution.
This is a working method according to claim 4.

An embodiment of the working method according to claim 5 is shown in FIG. 5 as a fifth embodiment.

In the working method according to claim 4, (9
) A working method in which a cylindrical (11) weight is placed on top of the aquaculture net, and the net is rolled and pressed while soaking is carried out, which is the working method described in claim 5, in which the net is attached to the leaves. Dead leaves and torn leaf pieces that are infected with dirt, bacteria, and diseases are
It mixes with air bubbles and floats on the surface of the treatment liquid, and along with the bubbles, it adheres to aquaculture nets and is transported out to sea.

The leaves, which have minute bubbles of treatment liquid attached to their front and back sides, float on the ocean for a long time.

Even at sea, ultrasonic waves are generated when air bubbles disappear.

(Effects of the Invention) The working method using the device according to the invention has the following effects.

1st Example (a) The task is easy and convenient since the work involves simply passing the work team under the net by straddling or passing through it without untying or tying the thin robes that tie the aquaculture net. (b) It is not necessary to soak seeds for a certain period of time in a processing solution that is flowing and generates rough waves due to air bubbles.According to experiments by the inventor, it is possible to achieve 80% in a stationary processing solution. In order to achieve the same cleaning and sterilization effect as when soaking the seeds for 1 minute, the treatment solution that is being fluidly stirred in the device of the present invention must be soaked for 1 minute.
It is sufficient to allow it to pass for 0 seconds.

This eliminates the heavy work of hoisting heavy aquaculture nets by hand and the scrubbing required to increase the effect of seed soaking, eliminating back pain and the risk of falling.

(C) The sterilizing and sterilizing cleaning effect due to the action of the jet of air bubbles ejected from a group of minute pores and the ultrasonic waves generated when the air bubbles disappear can be achieved only by their physical effects without using a treatment liquid. This can also be achieved by using a treatment liquid, but the effect increases synergistically if a treatment liquid is used.

Therefore, it is possible to exterminate pathogens and clean dirt with a thin treatment liquid.

Specifically, conventionally used treatment liquids based on organic acids are diluted 100 times with seawater, but according to the working method of the present invention, the solution can be diluted 200 to 300 times. .

(d) 11 The laver leaves growing densely in the breeding net are loosened by the flow of fine air bubbles rising from the bottom, and are evenly immersed in the treatment liquid on both the front and back.

(e) As mentioned above, due to the increase in the amount of bubbles due to the viscosity of the processing liquid, such as organic acid materials, the miniaturization, and the increase in the pharmacological action of the processing liquid due to the sterilizing cleaning action of ultrasonic waves and the thermal effect, Processing work can be carried out rationally using a thin processing liquid.

(f) The thin treatment liquid with fine bubbles adheres to the front and back of the leaves and floats on the ocean for a long time, so the effect lasts for a long time even after the work is done.

Second Embodiment The working effect is the same as the first embodiment, but the air supply device is not an engine-driven (5) blower but an (8)
) Since it is an air cylinder, there is no risk of engine trouble or running out of gas at sea.

Third Embodiment The container (3) shown in this example is mainly made of plastic such as FRP, but the inner surface is covered with a reflective material (8) made of hard material. Since the ultrasonic wave has a high reflectance and undergoes multiple reflections, high efficiency can be obtained with less energy input.

Cases where the container itself is made of a reflective material such as a stainless steel plate or an iron plate whose surface has been treated with enameled aluminum plate are also included in this category.

Fourth Embodiment This embodiment is a working method using the apparatuses of the first, second, and third embodiments, and the effects thereof have been described in detail in each column, so their explanation will be omitted here.

Fifth Example In the working method of the fourth example, the aquaculture net was immersed in the container by bending it under its own weight, but in this example, a cylindrical (1
0) Since the work is carried out by placing a weight and pressing it, it is possible to perform the processing work more completely and evenly.
