산업용 카트리지 필터{INDUSTRIAL CARTRIDGE FILTER}Industrial Cartridge Filters {INDUSTRIAL CARTRIDGE FILTER}

본 발명은 석유화학 수지 공정에서 사용되는 산업용 카트리지 필터에 관한 것으로서, 보다 상세히는 코아가 순간 선용접에 의해 형성되고, 상부 및 하부 캡이 메쉬 스폿 용접(mesh spot welding)에 의해 코아에 장착되는 산업용 카트리지 필터에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an industrial cartridge filter used in a petrochemical resin process, more particularly, in which an industrial core is formed by instantaneous pre-welding, and the upper and lower caps are mounted on the core by mesh spot welding. It relates to a cartridge filter.

도 1 및 도 2를 참조하면, 종래의 산업용 카트리지 필터는 코아(3)의 플랜지부(5)가 점용접(spot welding)에 의해 서로 용접되고, 상부캡(7)이 상기 코아(3)의 상부에 끼워맞춤 방식으로 장착되며, 상기 코아(3)의 하단부(11)가 본체에서 경사져 연장되며, 상기 상기 코아(3)의 하단부(11)가 "S" 형상으로 하부 캡(9)을 고정하는 브라켓(13)에 끼워진다.1 and 2, in the conventional industrial cartridge filter, the flanges 5 of the core 3 are welded to each other by spot welding, and the upper cap 7 is connected to the core 3. It is mounted in a fitting manner in the upper portion, the lower end 11 of the core 3 extends inclined from the main body, the lower end 11 of the core 3 is fixed to the lower cap (9) in the "S" shape Is fitted to the bracket (13).

그러나, 상기와 같이 구성된 종래의 산업용 카트리지 필터는 코아의 플랜지부가 점용접 방식으로 용접되기 때문에 상기 플랜지부가 반복적으로 가열되어 플랜지부에 부식이 발생하기 때문에 필터의 파손이 빈번하였고, 플랜지부에서 용접되지 않은 부분이 여과 기능을 갖지 못하여 이물질이 여과되지 않고 통과되며, 플랜지부의 반복가열로 인하여 캡이 이완되면서 상기 코아에서 캡이 탈락되는 문제점이 있었다.However, in the conventional industrial cartridge filter configured as described above, since the flange portion of the core is welded by spot welding, the flange portion is repeatedly heated and corrosion occurs in the flange portion. If the part does not have a filtration function, foreign matter is passed through without being filtered, and the cap is loosened from the core while the cap is relaxed due to repeated heating of the flange part.

또한, 도 3에 도시된 바와같이 다른 예의 산업용 카트리지 필터는 다수개의 사각형 망이 스폿용접에 의해 겹쳐진다.In addition, as shown in FIG. 3, in another example of the industrial cartridge filter, a plurality of rectangular meshes are overlapped by spot welding.

그러나, 이러한 산업용 카트리지 필터는 반복적인 가열로 용접부가 녹슬고, 필터링할 때 용접부가 집중압력을 받아 망이 서로 분리되는 문제점이 있었다.However, such an industrial cartridge filter has a problem in that the weld is rusted by repeated heating, and when the filter is filtered, the weld is subjected to concentrated pressure and the networks are separated from each other.

따라서, 본 발명의 목적은 코아의 플랜지부가 순간선용접 방식으로 용접되므로서 압력분산으로 제품의 수명이 연장되며, 상부캡이 하부캡이 각각 메쉬 스폿 용접되므로서, 상부캡과 하부캡이 코아에서 탈락되지 않는 산업용 카트리지 필터를 제공하는 것이다.Accordingly, an object of the present invention is to extend the life of the product by pressure dispersion as the flange portion of the core is welded by the instantaneous line welding method, the upper cap and the lower cap are respectively mesh spot welded, so that the upper cap and the lower cap in the core It is to provide an industrial cartridge filter that does not fall off.

상기와 같은 목적을 달성하기 위한 본 발명에 따른 산업용 카트리지 필터의 일례는 코아에 부직포가 감겨지고, 상기 코아의 상단부 플랜지에 상부캡이 장착되며, 상기 코아의 하단부 플랜지에 하부캡이 브라켓에 의해 장착되는 산업용 카트리지 필터에 있어서, 상기 코아는 측부 플랜지부가 순간선용접에 의해 서로 용접되고, 상단부 플랜지가 메쉬스폿용접된 후 상부캡의 장착부에 끼워지고, 하단부 플랜지가 본체에서 직각으로 굴절되고 메쉬스폿용접된 후 하부캡의 브라켓에 끼워지는 것을 특징으로 한다.An example of an industrial cartridge filter according to the present invention for achieving the above object is a nonwoven fabric wound around the core, the upper cap is mounted on the upper flange of the core, the lower cap is mounted on the lower flange of the core by the bracket In the industrial cartridge filter, the core is welded to each other by the instantaneous line welding of the side flange, the upper flange is fitted to the mounting portion of the upper cap after the mesh spot welded, the lower flange is bent at right angles in the body and the mesh spot welding After being fitted to the bracket of the lower cap.

상기 상부캡은 본체 하단에 본체보다 얇은 두께의 압착부가 구비되며, 상기 상부캡이 코아에 장착된 후, 상기 압착부가 롤링 등에 의해 코아의 상단부 플랜지에 완전 밀착되는 것을 특징으로 한다.The upper cap is provided with a pressing portion having a thickness thinner than the main body at the bottom of the main body, and after the upper cap is mounted on the core, the pressing part is completely adhered to the upper flange of the core by rolling or the like.

본 발명에 따른 산업용 카트리지 필터의 다른 예는 원형 또는 사각형 망사들의 모서리부가 순간선용접에 의해 서로 완전 용접되는 것을 특징으로 한다.Another example of the industrial cartridge filter according to the present invention is characterized in that the corner portions of the circular or square meshes are completely welded to each other by instantaneous welding.
