Manufacturing method of an electrochamber module used in a ballast water treatment system of a vessel{Manufacturing method of electro chamber module using in ballast water management system}

The present invention relates to a method for manufacturing an electro-chamber module used in a ballast water treatment system, the manufacturing process of the electro-chamber module is standardized, product standardization and quality assurance are achieved, and production efficiency is also maximized by reducing manpower and working time. It relates to a method of manufacturing an electro-chamber module used in a ballast water treatment system that can be.

Ballast water refers to seawater that is filled into tanks installed at the bottom or left and right of a ship to maintain the center of gravity of the ship when the ship is in operation. When the cargo is loaded, the seawater that was loaded is thrown away, and when the cargo is unloaded, the seawater is re-inserted and the vessel is centered. Through this, the center of gravity can be adjusted by balancing the left and right sides of the ship. I do not know if such ballast water is discharged to the sea without any problems, but ballast water is a major cause of various ecosystem disturbances and water pollution.

In order to prevent the destruction, disturbance and environmental pollution of the marine ecosystem, the International Maritime Organization (IMO) is obliged to install a ballast water management system (BWMS).

The ballast water treatment system (BWMS) is a facility that removes or sterilizes aquatic organisms and microorganisms in the ballast water, and when sterilized by an electrolysis method, an electrolysis module (electro chamber module) in which an electrolysis device is built-in ).

Since the electro-chamber module is used underwater, it must be manufactured to withstand water pressure or water pressure, which does not occur, and to combine with other components constituting the ballast water treatment system. It needs to be mass produced in a certain standard.

The electro-chamber module is provided with a housing 30 having flanges 31 on both sides of the body 10 having an upper plate 20 coupled to the upper portion as shown in FIGS. 1A to 1C, and the electro-chamber module Drain pipes 40 are provided at both upper and lower portions, respectively. In addition, a plurality of reinforcement bars may be arranged at predetermined intervals on the inner bottom surface and the inner both side surfaces or the outer both side surfaces of the body 10.

In order to manufacture the electro-chamber module, it is very important to combine the components in the body 10 at the correct position or arrangement and angle.

Conventionally, since the electro-chamber module was manufactured by using a tape measure or the like to mark the combined position or the welding position of the above-mentioned components and performing welding work or relying entirely on the skill of the operator, it takes a long time to manufacture, the production efficiency is low, and the quality reliability is high. There was also a problem of low.

Therefore, standardization of the manufacturing process is required to improve and improve the production efficiency and quality reliability of the electrochamber module.

When the top plate 101 is accurately disposed on the body 100, the first module body 200 is manufactured by performing primary welding and mounting welding (potential welding). (See Figure 5b)

Subsequently, the manufactured first module body 200 is fully welded to the inner and outer joining portions of the top plate 101 and the body 100 by using the straight welding apparatus 500 shown in FIG. 5C. The first module body 200 is completed.

The straight welding apparatus 500 is a device that automatically and accurately welds the inner and outer coupling portions of the upper plate 101 and the body 100 while the welding nozzle unit (not shown) moves in a straight line. Therefore, as a preferred embodiment of the first module body manufacturing step (S20), in the step (S20), the entire welding portion of the body 100 and the top plate 101 is quickly and precisely through the straight welding device 500. It may include a process.

The housing manufacturing step (S30) of the present invention is a step of manufacturing a housing 30 in which the housing base material 30A and the flange 31 are welded. In other words, it is a step of manufacturing the housing 30 by aligning the flange 31 shown in FIG. 6(a) on the upper portion of the housing base material 30A shown in FIG. 6(b), and then joining by welding.

As a preferred embodiment of the housing manufacturing step (S30), in the step (S30), the flange 31 is accurately aligned on the housing base material 30A using the third jig 130 shown in FIG. Can be welded.

First, referring to FIG. 7, the third jig 130 will be described.

The third jig 130 is the upper plate 131, the lower plate 132, and the upper plate 131 and the lower plate to separate the upper plate 131 and the lower plate 132 to a predetermined height ( 132) is made up of a plurality of leg portions 133 standing upright, the upper plate 131 is formed by being indented (있도록入) inside so as to place and pull out the flange 31 and the housing base material (30A) In addition to having the indentation portion 131A, the insertion hole 131B corresponding to the coupling hole 31A of the flange 31 is formed symmetrically, and the lower plate 132 is to be seated with a housing base material 30A. Fine seating portion 132A is formed at a predetermined depth so as to be able to be formed.

As a preferred embodiment of the present invention, the housing manufacturing step (S30) using the third jig 130 will be described in detail.

In the housing manufacturing step (S30), first, as shown in FIG. 8A, first, the housing base material 30A having a predetermined height is placed on the seating portion 132A of the lower plate 132, and then the flange 31 While the coupling hole 31A corresponds to the insertion hole 131B of the upper plate 131, the flange 31 is disposed on the upper side of the housing base material 30A, and then the fixing pin P is symmetrical to the left and right. (31A) is inserted into the insertion hole (131B).

According to the method, the flange 31 on the housing base material 30A having a predetermined height can be accurately aligned with respect to a specific point of the housing base material 30A, so that the flange 31 and the housing base material 30A When welding between ), product standardization can be achieved.

The reason why the flange 31 should be accurately aligned with the housing base material 30A is that the electrochamber module should be connected to or coupled with other equipment or modules through the coupling hole 31A of the flange 31, and the position of the coupling holes between each other This is because, if they do not correspond to each other, the fastening means may be fastened to each other to prevent penetration.

Subsequently, by aligning the flange 31 on the housing base material 30A and fixing it with a fixing pin P, the housing base material 30A is welded (potentially welded) to the joint portion of the housing base material 30A and the flange 31 by welding. ) And the flange 31 is first coupled, the fixing pin P is removed, and the housing 30 in which the housing base material 30A and the flange 31 are combined is taken out from the third jig 130.
