분체도장용 건조 시스템{Drying system for powder coating}Drying system for powder coating

본 발명은 분체도장용 건조 시스템에 관한 것으로, 보다 상세하게는 가열된 공기가 큰 열저항없이 열순환될 수 있도록 하여 연료비를 줄이고, 환경적 위해요인 발생을 억제하여 친환경적인 분체도장 환경을 만들 수 있으면서 가열 효율을 증대시키도록 개선된 분체도장용 건조 시스템에 관한 것이다.The present invention relates to a drying system for powder coating, and more particularly, it is possible to reduce fuel costs by allowing heated air to be thermally circulated without large thermal resistance, and to suppress the occurrence of environmental hazards to create an environment-friendly powder coating environment. It relates to a drying system for powder coating improved to increase heating efficiency while still being there.

일반적으로 완성된 제품을 도장하는 방법으로 분체도장이 널리 사용되고 있는데, 이러한 분체도장은 공정이 간단하여 자동화가 용이하고, 작업성이 우수하며, 1회 도포로도 소정 두께의 도막을 형성시킬 수 있는 장점이 있다.In general, powder coating is widely used as a method of painting finished products. Such powder coating is a simple process, which makes it easy to automate, has excellent workability, and can form a coating film of a predetermined thickness even with one application. There are advantages.

보통, 분체도장(Powder Coating)이란 용제나 희석제를 함유하지 않은 100% 고형분 분말을 정정 스프레이 방식 등으로 도장한 후 고온에서 후가열 용융하여 도막화시키는 기술을 말한다.In general, powder coating refers to a technology in which 100% solid powder containing no solvent or diluent is coated by a correction spray method, etc., and then melted by post-heating at a high temperature to form a coating film.

이러한 분체도장 공정 중 도장면을 확립하기 위해 건조로에서 건조되게 된다.During this powder coating process, it is dried in a drying furnace to establish a painted surface.

종래 건조로 시스템은 가스를 사용하여 버너로 다수의 철판을 달군 후 고온공기를 만들어 도장건조로 하부로 공급하고, 건조를 진행하는 도중에 약 20%의 공기는 벤트시키며, 나머지 80%는 다시 회수하여 재차 가열 후 다시 공급하는 과정을 반복하도록 설계되어 있다.The conventional drying furnace system uses gas to heat a number of iron plates with a burner, produces high-temperature air and supplies it to the lower part of the painting drying furnace, vents about 20% of the air during drying, and recovers the remaining 80%. It is designed to repeat the process of re-supplying after heating again.

그런데, 이러한 종래 건조로 시스템은 가스를 연료로 사용하기 때문에 연소시 완전연소가 되지 못함에 의해 발생되는 일산화탄소/이산화탄소 등에 의한 환경오염의 문제로 인해 최근 친환경 정책에 따른 제약이 많다.However, since the conventional drying furnace system uses gas as a fuel, there are many restrictions according to recent eco-friendly policies due to the problem of environmental pollution caused by carbon monoxide/carbon dioxide, etc., which is caused by failure to achieve complete combustion during combustion.

또한, 균일한 온도의 고온 공기를 연속적으로 만들기 위해 다수의 지그재그형 철판을 달구도록 되어 있어 철판을 달구는데 필요한 가동시간과 비용낭비로 인해 매우 비효율적인 구조를 가지고 있다.In addition, a plurality of zigzag-type iron plates are heated to continuously make high-temperature air of a uniform temperature, so it has a very inefficient structure due to operation time and cost waste required to heat the iron plates.

뿐만 아니라, 만들어진 고온공기를 공급할 때 지그재그로 배열된 철판들 사이를 지나 공급되어야 하므로 열순환시 유로가 길어져 유로저항이 커지는 단점이 있다.In addition, when supplying the made high-temperature air, it has to be supplied through between the iron plates arranged in a zigzag, so there is a disadvantage in that the flow path becomes long during thermal circulation, which increases the flow path resistance.

이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

본 발명에 따른 분체도장용 건조 시스템의 가장 큰 특징은 연료로 가스를 사용하지 않아 불완전연소로 인해 발생되는 환경저해 요인을 제거한 친환경적인 건로로를 구현하는데 있으며, 이로 인해 연료 소모에 따른 비용낭비로 막고, 유로 저항을 줄여 효율적인 건조로 시스템을 구축하는데 있다.The biggest feature of the drying system for powder coating according to the present invention is to implement an eco-friendly dry furnace that eliminates environmental obstacles caused by incomplete combustion by not using gas as fuel, and thus, it is a waste of money due to fuel consumption. It is to build an efficient drying furnace system by reducing the flow resistance.

이를 위해, 본 발명에 따른 분체도장용 건조 시스템은 도 1에 예시된 바와 같이, 가열부(100)와 도장건조부(200)를 포함하며, 상기 가열부(100)에서 가열된 고온 공기를 도장건조부(200)로 반송하는 공급관부(300)와, 상기 도장건조부(200) 내부를 건조한 공기를 다시 가열부(100)로 회수시켜 재가열하도록 하는 회수관부(400)를 더 포함한다.To this end, the drying system for powder coating according to the present invention includes a heating unit 100 and a painting drying unit 200 as illustrated in FIG. 1 , and coating the high-temperature air heated by the heating unit 100 . It further includes a supply pipe unit 300 for conveying to the drying unit 200 and a recovery pipe unit 400 for reheating the dry air inside the painting drying unit 200 by recovering it to the heating unit 100 again.

그리고, 상기 도장건조부(200)에는 내부압을 조절하면서 공기 순환을 원활하게 하기 위해 천정면에 벤트홀(210)이 형성된다.In addition, in the painting drying unit 200, a vent hole 210 is formed in the ceiling surface to facilitate air circulation while controlling the internal pressure.

그리하여, 공급된 고온 공기중 도장건조부(200) 내부에서 건조에 사용된 후 약 20%는 벤트홀(210)을 통해 대기중으로 벤트되고, 나머지 80%의 온도가 떨어진 사용 공기는 회수관부(400)를 통해 가열부(100)로 회수되어 재가열되게 된다.Thus, about 20% of the supplied high-temperature air after being used for drying in the paint drying unit 200 is vented to the atmosphere through the vent hole 210, and the remaining 80% of the used air having a lowered temperature is the recovery pipe unit 400 ) is recovered to the heating unit 100 through the reheating.

이때, 상기 가열부(100)는 도 2 및 도 3의 예시와 같이, 함체인 가열하우징(110)과, 상기 가열하우징(110)의 바닥면에 설치된 가열원인 인덕션(120)과, 상기 인덕션(120) 상부에 배치된 다수의 히팅플레이트(130)와, 상기 히팅플레이트(130)에 의해 데워진 공기를 공급관부(300)로 송풍하는 공급팬(140)을 포함한다.At this time, as in the example of FIGS. 2 and 3 , the heating unit 100 includes a heating housing 110 as a housing, an induction 120 as a heating source installed on the bottom surface of the heating housing 110, and the induction ( 120) a plurality of heating plates 130 disposed on the upper portion, and a supply fan 140 that blows the air heated by the heating plate 130 to the supply pipe part 300 .

이와 같이, 본 발명에서는 가열원으로 가스(Gas)를 사용하지 않고 전기에너지를 이용하여 직접 가열하는 히팅 방식을 사용하기 때문에 폐가스가 발생하지 않아 친환경적이다.As described above, since the present invention uses a heating method that directly heats using electric energy without using a gas as a heating source, waste gas is not generated, which is eco-friendly.

특히, 인덕션(120)을 사용하기 때문에 가동시간이 짧고 높은 온도까지 쉽게 올릴 수 있다.In particular, since the induction 120 is used, the operating time is short and the temperature can be easily raised to a high temperature.

다만, 열이 빨리 식지 않도록 하기 위해 히팅플레이트(130)를 포함하는데, 상기 히팅플레이트(130)는 기존 지그재그형 철판과 달리 일정간격을 두고 다수개가 라인상으로 배열된 라인형 혹은 격자형을 갖도록 하여 고온 공기가 공급될 때 유로저항이 전혀 발생하지 않도록 설계된다. 때문에, 공급 효율이 매우 우수하게 된다.However, it includes a heating plate 130 to prevent the heat from quickly cooling, and the heating plate 130 has a line-type or grid-type in which a plurality of them are arranged in a line at regular intervals, unlike the existing zig-zag-type iron plate. It is designed so that no flow resistance occurs when hot air is supplied. Therefore, the supply efficiency becomes very excellent.

뿐만 아니라, 상기 공급관부(300)는 공급효율을 높이기 위해 양방향으로 분기되어 피건조체(D)가 장입되어 있는 도장건조부(200)의 양측으로 공급될 수 있도록 배관되며, 이러한 구조는 상기 회수관부(400)에도 동일하게 적용된다.In addition, the supply pipe part 300 is branched in both directions to increase supply efficiency and is piped to be supplied to both sides of the painting drying part 200 in which the object to be dried (D) is charged. The same applies to (400).

여기에서, 공급효율이란 고온 공기가 최대한 식지 않고 일정온도를 유지한 채 도장건조부(200)로 공급되는 비율을 말한다.Here, the supply efficiency refers to the rate at which the high-temperature air is supplied to the painting drying unit 200 while maintaining a constant temperature without cooling as much as possible.

아울러, 상기 히팅플레이트(130)는 막대형 히트파이프를 사용하면 더욱 좋다.In addition, it is better if the heating plate 130 uses a rod-type heat pipe.

막대형 히트파이프는 가열능력과 열보지력(熱保持力)이 뛰어나기 때문에 고온 공기를 만들고 유지시키는데 매우 유리하다.The rod-type heat pipe is very advantageous in making and maintaining high-temperature air because it has excellent heating ability and heat retention.

또한, 상기 공급관부(300)와 회수관부(400)를 구성하는 배관, 즉 파이프는 도시상 편리하게 도식화하기 위해 사각파이프 형태로 도시하였으나 원형 파이프 형태로 구현하는 것이 더욱 바람직하다.In addition, although the pipe constituting the supply pipe part 300 and the return pipe part 400, that is, the pipe, is shown in the form of a square pipe for convenient schematic drawing, it is more preferable to implement it in the form of a round pipe.

덧붙여, 본 발명에서는 공급관부(300)를 통해 고온 공기가 공급될 때 유발될 수 있는 열손실을 줄이고, 항온성을 유지하여 건조효율을 높이도록 공급관부(300)의 길이 중간에 도 4와 같은 가온조(500)를 더 구비할 수 있다.In addition, in the present invention, in the middle of the length of the supply pipe 300 to reduce the heat loss that may be caused when high-temperature air is supplied through the supply pipe 300, and to maintain the constant temperature to increase the drying efficiency, as shown in FIG. A heating tank 500 may be further provided.

상기 가온조(500)는 일종의 튜브형 순간가열기로서 필름히터를 이용하여 저전력으로 순간 높은 온도까지 가열할 수 있어 공급관부(300)를 관류하는 공기의 온도 저하를 방지하는 역할을 담당한다.The heating tank 500 is a kind of tubular instantaneous heater that can be heated to a high instantaneous temperature with low power using a film heater, thereby preventing a decrease in the temperature of the air flowing through the supply pipe part 300 .

이를 위해, 상기 가온조(500)는 공급관부(300)를 배관하기 전에 공급관부(300)에 먼저 끼워져 공급관부(300)와의 사이에 항온챔버(510)를 형성하는 스테인레스스틸관(520)과, 상기 스테인레스스틸관(520)의 외부면에 밀착된 절연층(530)과, 상기 절연층(530)의 외부면에 밀착된 저항층(540)과, 상기 저항층(540)의 외주면에 밀착된 도체층(550)과, 상기 도체층(550)의 외부면에 밀착된 절연보호층(560)으로 이루어진다.To this end, the heating tank 500 is inserted into the supply pipe part 300 before piping the supply pipe part 300 to form a constant temperature chamber 510 between the supply pipe part 300 and a stainless steel pipe 520 and , the insulating layer 530 in close contact with the outer surface of the stainless steel tube 520 , the resistance layer 540 in close contact with the outer surface of the insulating layer 530 , and the resistance layer 540 in close contact with the outer peripheral surface of the resistance layer 540 . formed of a conductive layer 550 and an insulating protective layer 560 in close contact with the outer surface of the conductive layer 550 .

이때, 스테인레스스틸관(520)은 SUS430으로 제조됨이 바람직하며, 내식성과 우수한 열전도성을 갖는 재료로 만들어짐이 바람직하다.At this time, the stainless steel tube 520 is preferably made of SUS430, and is preferably made of a material having corrosion resistance and excellent thermal conductivity.

그리고, 스테인레스스틸관(520)을 지지고정하기 위해 리브(522)가 돌출되며, 상기 리브(522)는 상기 스테인레스스틸관(520)과 공급관부(300) 사이의 간격을 유지시켜 항온챔버(510)를 형성하게 된다.Then, a rib 522 protrudes to support and fix the stainless steel pipe 520, and the rib 522 maintains a gap between the stainless steel pipe 520 and the supply pipe part 300 to maintain a constant temperature chamber 510. ) is formed.

뿐만 아니라, 상기 가온조(500)가 설치된 후에는 가온조(500)의 양단을 씰링재(예. 실리콘 혹은 내열성 씰링재)로 밀봉하여 항온챔버(510) 내부의 가열된 공기가 외부로 빠져나가지 못하도록 구성된다. 때문에, 항온챔버(510) 내부의 공기는 항상 원하는 온도 수준으로 가열된 상태를 유지하고 있어 열교환에 의해 열을 공급할 수 있는 구조가 된다.In addition, after the heating tank 500 is installed, both ends of the heating tank 500 are sealed with a sealing material (eg, silicone or heat-resistant sealing material) to prevent the heated air inside the constant temperature chamber 510 from escaping to the outside. do. Therefore, the air inside the constant temperature chamber 510 is always heated to a desired temperature level, and thus has a structure capable of supplying heat through heat exchange.

그리고, 상기 절연층(530)은 저항층(540)에 인가되는 전류가 스테인레스스틸관(520)으로 흐르지 않도록 차단하기 위한 것으로, 공지된 절연재면 족하다.In addition, the insulating layer 530 is to block the current applied to the resistance layer 540 from flowing to the stainless steel tube 520 , and a known insulating material is sufficient.

아울러, 상기 저항층(540)은 일종의 패턴 필름히터로서, 저전력으로도 높은 발열량(Heat Generation)을 낼 수 있는 팔라듐 실버 패턴 필름히터가 사용된다.In addition, the resistive layer 540 is a kind of pattern film heater, and a palladium silver pattern film heater capable of generating high heat generation even with low power is used.

또한, 상기 도체층(550)은 실버 도체로서 저항층(540)에서 발열된 고온의 열량이 외부로 누설되지 않고 그대로 다시 반사되게 하여 스테인레스스틸관(520)을 급속 가열하는데 조력하기 위해 구비된다.In addition, the conductor layer 550 is a silver conductor and is provided to assist in rapidly heating the stainless steel tube 520 by allowing the high-temperature heat generated by the resistance layer 540 to be reflected back as it is without leaking to the outside.

뿐만 아니라, 상기 저항층(540)에는 통전단자(미도시)가 구비되어 전기를 통할 수 있도록 구성된다.In addition, the resistive layer 540 is provided with a conducting terminal (not shown) to allow electricity to pass through.

그리하여, 건조로 시스템을 구동할 때 컨트롤러(미도시)의 제어에 의해 가온조(500)의 발열에 의해 항온챔버(510) 내부의 온도는 항상 일정하게 유지되고, 따라사 공급관부(300)를 따라 관류하던 공기는 간접 열교환에 의해 열이 보상되어 도장건조부(200)로 공급될 때 항상 일정한 온도 이상으로 공급되게 되어 도장 품질을 높이는데 기여하게 된다.Therefore, when the drying furnace system is driven, the temperature inside the constant temperature chamber 510 is always kept constant by the heat of the heating tank 500 under the control of the controller (not shown), and the supply pipe part 300 is The air that has flowed through is always supplied at a constant temperature or higher when the heat is compensated by indirect heat exchange and supplied to the painting drying unit 200, thereby contributing to improving the painting quality.
