Description

TECHNICAL FIELD [0001] The present invention relates to an epoxy inside dispenser for welding a steel mesh filter,

The present invention relates to a method for manufacturing a steel mesh for ships, which is manufactured by integrating each mesh network by wrinkle processing by pressing multiple layers of metal meshes having different mesh sizes and then welding the mesh portions of the mesh by rolling them into a cylindrical shape In the filter, an epoxy resin is applied along a straight line weld line formed in the longitudinal direction of the filter body. In addition, an epoxy resin is applied to the inner welding line of the cylindrical steel mesh filter, which is almost impossible to finish by hand or dispenser method. The present invention relates to an inside dispenser for easily and accurately performing a finishing process.

Generally, a steel mesh filter, which is generally used for ships, is formed by folding a plurality of metal meshes having different meshes (meshes) and pressing the metal meshes together so that the entire mesh of metal is corrugated The metal body is formed into a net shape, and then the metal body is wound in a cylindrical shape to weld a connecting portion where both side edges of the metal mesh are butted against each other, thereby manufacturing a filter body that provides a filtering base.

The filter body may be formed into a cylindrical shape having the same diameter along the longitudinal direction by cutting a plurality of metal net meshes integrated into a rectangular plate shape, cutting the mesh net into a trapezoidal shape, and gradually increasing its diameter toward one side A metal filter case of a cylindrical shape corresponding to the filter body is covered on the outer surface of the filter body and a metal filter cap is attached to both ends of the filter body Assembled and fixed, and the filter body and the filter casing are integrally connected to each other to complete the manufacture of the steel mesh filter.

Therefore, in the case of a steel mesh filter for ships, a linear weld line is inevitably generated along a portion where the metal mesh is stuck over the longitudinal direction of the cylindrical filter body providing the filtering base, It is very vulnerable to corrosion. Therefore, when the welding line of the filter body is left as it is, due to the characteristics of the marine filter exposed to a severe corrosive environment under relatively high temperature and pressure conditions, Lt; / RTI >

In order to solve the above problems, the epoxy resin is applied along the welding line of the filter body, and then the epoxy resin is thermally cured so as to finish the welding part. Or a dispenser such as that described in Korean Patent Laid-Open No. 10-2012-0082677 may be used, but both methods are limited to the finishing of the weld line exposed to the outside of the cylindrical filter body There is a problem that it is practically impossible to apply to the finishing treatment of the welding line existing inside the cylindrical filter body.

In other words, since the marine steel mesh filter has a diameter of about 5 to 15 cm and a length of about 1 to 1.5 m, it is possible to prevent the spraying of the epoxy resin or the spray nozzle from moving along the inner space of the filter body, The work of accurately applying the epoxy resin to the welding line on the side of a certain thickness is very complicated. As a result, since the epoxy resin finish treatment is not properly performed on the inner welding line of the filter body, the steel mesh filter It is difficult to ensure sufficient pressure resistance performance and service life at a required level.

Particularly, since the situation where the welding line is gradually corroded from the inside can not be prevented at all, corrosion and cracking due to high temperature and high pressure are started to occur from the inner welding line within a relatively short period, (Ballast water) or fuel oil or lubricating oil supplied to various main facilities including the engine of the ship, and the like, And it has become a factor to cause a serious obstacle to the stable operation of the ship.
