In the exhaust duct (30), stepped protrusions (31a, 32a) for bending ends of an upper exhaust tube (31) and a lower exhaust tube (32) outward to face each other are formed, and supporting plates (33, 33′), each of which has a washer shape, are respectively inserted into the upper exhaust tube (31) and the lower exhaust tube (32) and hung on the stepped protrusions (31a, 32a), and then both supporting plates (33, 33′) are fixed by using spot welding so that both supporting plates are closely attached to each other, and a circumference of each of both supporting plates (33, 33′) is inserted into a bending piece (13) formed on a circumference of an upper end of the main body (10) and bent inward to be connected to the main body (10).

Description

보일러용 사이클론 집진기{Boiler cyclone dust collector}Boiler cyclone dust collector

본 고안은 보일러용 사이클론 집진기에 관한 것으로, 좀더 상세하게는 사이클론 집진기의 결합구조를 금속판재의 판금 접합구조에 의하여 형성하도록 하는 보일러용 사이클론 집진기에 관한 것이다.
The present invention relates to a cyclone dust collector for a boiler, and more particularly, to a cyclone dust collector for a boiler in which a coupling structure of a cyclone dust collector is formed by a sheet metal joining structure of a metal plate.

일반적으로 보일러용 사이클론 집진기는 보일러에서 연소과정에서 나오는 각종 먼지를 포함한 공기에 선회 운동을 주어 입자의 원심력을 이용해서 분진 입자를 분리하여 각종 오염 먼지를 수거하도록 한 것이다.Generally, a cyclone dust collector for a boiler circulates the air including various dusts generated in the combustion process in the boiler, and separates the dust particles by centrifugal force of the particles to collect various polluted dusts.

이러한 사이클론 집진기는 주물로 제작되거나 금속판재로 제작되고 있는바, 주물로 제작되는 것은 견고성이 높으나 제작단가가 상당히 높아 특수한 부분에 적용되고 있다.Such a cyclone dust collector is made of a casting or a metal plate, and since the casting is made of a cast iron, its robustness is high, but its production cost is very high and it is applied to a special part.

금속판재로 제작되는 것은 각 연결 결합부분의 둘레를 연속적인 용접에 의하여 제작되고 있고 용접을 하기 위해서는 금속판재의 두께가 어느 정도 있어야 용접이 원활하게 이루어질 뿐만 아니라 변형을 막을 수 있으나 모든 연결부분을 용접에 의하여 연결되기 때문에 작업시간이 상당히 소요될 뿐만 아니라 금속재의 두께가 클수록 재료 단가가 높아지게 되므로 제작단가 높아지는 등의 문제점이 있다.The metal plate is made by continuous welding around each connecting joint. In order to do welding, the thickness of the metal plate should be enough to prevent the welding as well as to prevent deformation. However, The time required for the operation is considerably increased. In addition, the larger the thickness of the metal material, the higher the unit cost of the material, and the manufacturing cost is increased.

특히 금속판재는 대부분 녹방지 등이 되는 스테인레스 재질의 판재를 적용하기 때문에 특수한 용접작업에 의하여 이루어지고 있다.
Particularly, the metal plate material is made by a special welding operation because a plate material made of stainless steel which is mostly used for preventing rust is applied.

The upper and lower exhaust pipes and the lower exhaust pipe are fitted with a support plate, respectively, and then the support plates are fixed by spot welding so as to be brought into close contact with each other so that they are in close contact with each other. Then, the periphery of both support plates is inserted into the bending portion formed around the upper end of the body, .

본 발명은 본체에 배기덕트를 연결 때 연결부분의 둘레를 연속적인 용접으로 연결하지 않고 접합방식에 의하여 결합되도록 하므로 얇은 금속판재를 적용할 수 있어 제작단가를 대폭적으로 절감할 수 있을 뿐만 아니라 제작공정이 간편한 효과를 갖는다.
The present invention can be applied to the exhaust duct by connecting the periphery of the connecting portion by continuous welding without connecting the exhaust duct when the exhaust duct is connected to the main body. Therefore, a thin metal plate can be applied, This has a simple effect.
