Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an acid treatment method for a seaweed net and an acid-treated ship for effectively treating the seaweed net spread on a seaweed farm by a strut system.

[0002]

2. Description of the Related Art Generally, seaweed is cultivated by a pillar system in which a seaweed net is stretched on a pillar standing in the sea. In the cultivation of such seaweed, the quality of the seaweed, such as seaweed nets and the surface of the seaweed that grows on the seaweed nets, such as the deposits of seawater scales and debris, and the growth of various bacteria, are observed. There is a factor that lowers it. Therefore, in order to grow high-quality and healthy seaweed and improve the yield, the seaweed net is subjected to acid treatment. In the conventional ordinary acid treatment method, an acid treatment mechanism consisting of an acid treatment tank is installed on the ship, and the seaweed net spread on the sea surface is temporarily lifted on the ship and allowed to pass through the acid treatment tank for a certain period of time. Then, it will be expanded again on the sea surface.

FIG. 7 and FIG. 8 show an example of such a conventional acid treatment vessel. In this acid treatment vessel, an acid treatment mechanism consisting of an acid treatment tank is installed on the vessel and the acid treatment vessel is spread on the sea surface. The seaweed net is temporarily fried on a ship and allowed to pass through the acid treatment tank for a certain period of time for dipping, and then spread again on the sea surface.

To further explain, FIG. 7 shows an acid treatment vessel 3 in which an acid treatment mechanism 1 according to the conventional acid treatment method of this kind is installed on a vessel 2, and an edge of a substantially box-shaped hull 4 in the longitudinal direction. The edges 5a and 7b of the acid treatment mechanism 1 which is made of FRP or the like and also serves as the substantially box-shaped acid treatment tank 6 and which is also made of FRP are covered and locked to the hull 4. ing.

In the longitudinal direction of the acid treatment tank 6 of the acid treatment mechanism 1, as shown in FIG. 9, a clip or the like attached to the end of the mooring rope 9 locked at a predetermined position of the support column 8 is provided. Nori net 1 moored in a stretched state by a simple attaching / detaching means 10.
Two take-up rollers 12a, 12b, which are made of a corrosion-resistant metal or the like that winds up or squeezes 1 and is assembled in a substantially polygonal cross section, are rotatably arranged at predetermined positions. The take-up rollers 12a and 12b are provided on one side surface in the longitudinal direction outside the acid treatment tank 6 of the acid treatment mechanism 1.
A motor 13 which is a drive source for driving the winding roller 1 is attached by a driving force transmission mechanism 14.
It is connected to one end of 2a, 12b. This drive force transmission mechanism 14 is often used with a clutch function, and when the motor 13 is in operation, the take-up rollers 12a, 12
The driving force can be interrupted independently for each b. The take-up rollers 12a and 12b are rotatable by the clutch function of the driving force transmission mechanism 14 in a free state where the driving force is cut off.

FIG. 8 is a sectional view of a main part of the acid treatment mechanism 1. The acid treatment method of the seaweed net 11 by the acid treatment vessel 3 will be described with reference to FIG. A predetermined amount of the acid treatment liquid is put in the treatment tank 6 and spread by a simple attaching / detaching means 10 such as a clip attached to an end portion of the mooring rope 9 locked at a predetermined position of the column 8 as shown in FIG. The one end of the seaweed net 11 which is moored in the state
