본 발명은 열풍 및 열원을 이용한 건조장치에 관한 것으로써, 더 상세하게는 열원의 오염을 방지하고 고효율의 에너지로 건조속도를 증진시킨 열풍 및 열원을 이용한 건조장치에 관한 것이다.The present invention relates to a drying apparatus using a hot air and a heat source, and more particularly, to a drying apparatus using a hot air and a heat source which prevents contamination of the heat source and promotes drying speed with high efficiency energy.

예컨대, 종이 또는 합성수지필름과 같은 베이스의 표면에 실버코팅 또는 자외선도료 코팅 등을 행한 후에는 코팅층을 건조시키거나 경화시키도록 건조장치를 통과시켜 가열시키고 있다.For example, after silver coating or ultraviolet coating coating is performed on the surface of a base such as paper or a synthetic resin film, it is heated by passing through a drying apparatus to dry or cure the coating layer.

이는 표면에 코팅층을 형성한 베이스를 컨베이어에 탑재하여 건조장치에 통과시켜서, 건조장치의 히터와 같은 열원의 가열로 코팅층이 건조 또는 경화되도록 하고 있다.This allows a base having a coating layer formed on its surface to be mounted on a conveyor and passed through a drying apparatus so that the coating layer is dried or cured by heating a heat source such as a heater of the drying apparatus.

이와 같은 건조장치는 코팅층을 소망하는 건조상태로 건조시키거나 경화시키기 위하여는 건조장치 내부가 필요한 온도에 도달해야 소망하는 상태로 건조나 경화가 진행되므로 소망하는 온도 도달시간까지 상당한 시간이 요구된다.In order to dry or cure the coating layer in a desired drying state, such a drying apparatus requires a considerable time until the desired temperature reaching time because drying or curing proceeds to a desired state when the inside of the drying apparatus reaches a required temperature.

이때 종이 또는 합성수지필름과 같은 베이스의 표면이 히터열에 의해서 변형되는 문제점이 있게 된다.At this time, there is a problem that the surface of the base such as paper or synthetic resin film is deformed by the heat of the heater.

또한, 코팅부분의 건조시 건조열에 의해 증발되는 수분으로 히터부분이 오염되며, 이로인하여 에너지효율이 떨어지게되는 문제점이 있다.In addition, the heater portion is contaminated with moisture evaporated by the drying heat during drying of the coating portion, thereby causing a problem that the energy efficiency is lowered.

본 발명의 과제는 열원의 오염을 줄여 에너지효율을 높인 열풍 및 열원을 이용한 건조장치를 제공하는 데 있다.An object of the present invention is to provide a drying apparatus using a hot air and a heat source to reduce the pollution of the heat source to increase the energy efficiency.

본 발명의 과제는 피건조물의 건조속도를 증진시킨 열풍 및 열원을 이용한 건조장치를 제공하는 데 있다.An object of the present invention is to provide a drying device using a hot air and a heat source to increase the drying speed of the object to be dried.

상기 본 발명의 과제를 달성하는 본 발명은 피건조물의 표면을 가열하여 건조시키는 건조장치에 있어서,The present invention to achieve the object of the present invention is a drying apparatus for heating and drying the surface of the object to be dried,

상기 오목한 반사판의 중심부에 위치되어서 전원의 공급으로 발열되며, 상기 피건조물의 표면을 직접 가열 및 상기 반사판으로부터 반사되는 열원으로 가열시키는 열원과;A heat source positioned at the center of the concave reflector to generate heat by supply of power, and to directly heat the surface of the object to be heated by a heat source reflected from the reflector;

상기 열원의 가열에 의해서 가열되어진 상기 케이스의 내부공간에 공기를 공급시켜서 가열되어진 공기를 상기 열풍토출구멍을 통하여 상기 피건조물의 표면에 토출시키는 블로워;를 구비한 것을 특징으로 한다.And a blower for supplying air to the inner space of the case heated by the heat source and discharging the heated air to the surface of the dry object through the hot air discharge hole.

본 발명 건조장치는 상기 반사판에 반사된 열원과 상기 열풍토출공을 통하여 토출되는 열풍이 상기 피건조물의 동일 또는 상호 인접한 부분에 집원 또는 집풍되도록 한 것을 특징으로 한다.The drying apparatus of the present invention is characterized in that the heat source reflected by the reflector and the hot air discharged through the hot air discharge holes are collected or collected in the same or adjacent parts of the object to be dried.

또한, 본 발명 장치는 상기 열원은 0.8∼1.5㎛의 파장을 가지는 근적외선램프인 것을 특징으로 한다.The apparatus of the present invention is further characterized in that the heat source is a near infrared lamp having a wavelength of 0.8 to 1.5 mu m.

본 발명 건조장치는 열풍토출에 의해서 에어나이프(air knife)를 형성하여 피건조물의 건조시 증발되는 수분을 차단시킴으로써 열원이 오염되는 것을 방지시키고, 또한 열풍으로 인해 건조속도를 높인다.The drying apparatus of the present invention forms an air knife by hot air discharging, thereby preventing moisture from being contaminated by blocking moisture evaporated during drying of the dry item, and also increases the drying speed due to hot air.

또한, 반사판에 의한 열원의 반사로 피건조물의 표면에 집광시킴으로써 열효율을 높이며, 특히 근적외선의 사용으로 높은 열효율을 얻을 수 있다.Further, the heat efficiency is increased by condensing on the surface of the dry object by the reflection of the heat source by the reflecting plate, and in particular, high thermal efficiency can be obtained by using near infrared rays.

도 1은 종이 또는 합성수지필름과 같은 베이스(41)의 표면에 실버코팅 또는 자외선도료 등의 코팅층(42)이 형성된 피건조물(40)의 코팅층(42)을 건조시키거나 경화시키도록 가열시키는 본 발명 실시예의 건조장치를 나타낸다.FIG. 1 is the present invention which heats to dry or cure a coating layer 42 of a dry matter 40 on which a coating layer 42 such as silver coating or ultraviolet paint is formed on a surface of a base 41 such as paper or a synthetic resin film. The drying apparatus of the Example is shown.

실시예의 건조장치는 내부에 공간(11)이 형성되고, 그 하면에 상기 공강(11)측으로 오목한 반사판(12)이 형성되며, 상기 반사판(12)의 단부 가장자리에 상기 내부공간(11)과 통하는 열풍토출구멍(13)이 형성된 케이스(10)와;In the drying apparatus of the embodiment, a space 11 is formed therein, and a reflecting plate 12 concave toward the cavity 11 is formed on a lower surface thereof, and the inner space 11 communicates with the inner space 11 at an end edge of the reflecting plate 12. A case 10 having a hot air discharge hole 13 formed therein;

상기 오목한 반사판(12)의 중심부에 위치되어서 전원의 공급으로 발열되며, 상기 피건조물(40)의 표면을 직접 가열 및 상기 반사판(12)으로부터 반사되는 반사광원으로 가열시키는 열원(20)과;A heat source 20 positioned at the center of the concave reflection plate 12 to generate heat by supplying power, and directly heating the surface of the object 40 to a reflection light source reflected from the reflection plate 12;

상기 열원(20)의 가열에 의해서 가열되어진 상기 케이스(10)의 내부공간(11)에 공기를 공급시켜서 가열되어진 공기를 상기 열풍토출구멍(13)을 통하여 상기 피건조물(40)의 코팅층(42) 표면에 토출시키는 블로워(30);를 구비한다.The coating layer 42 of the to-be-dried object 40 is heated by supplying air to the internal space 11 of the case 10 heated by the heat source 20 through the hot air discharge hole 13. Blower 30 to be discharged to the surface;

또한, 상기 반사판(12)은 반사된 반사열원과 상기 열풍토출공(13)을 통하여 토출되는 열풍이 상기 피건조물(40)의 동일 또는 상호 인접한 부분에 집원 또는 집풍되도록 오목하게 형성된다.In addition, the reflective plate 12 is formed to be concave so that the reflected reflective heat source and the hot air discharged through the hot air discharge holes 13 are collected or collected in the same or adjacent parts of the object 40.

상기 반사판(12)은 알루미늄과 같은 금속판으로 형성하여서, 열원(20)ㅇㄹ 반사시킬 뿐만 아니라 케이스(10) 자체를 가열시켜서 공급되는 공기를 가열시키기도 한다.The reflecting plate 12 is formed of a metal plate such as aluminum, and not only reflects the heat source 20 but also heats the air supplied by heating the case 10 itself.

상기 열원은 0.8∼1.5㎛의 파장을 가지는 근적외선램프가 사용된다.The heat source is a near infrared lamp having a wavelength of 0.8 ~ 1.5㎛.

상기 근적외선은 열의 전달이 열 대류 방식에 의한 전달이 아니고, 빛 에너지에 의한 복사열 방식으로 직접적인 열이 전달되므로 중간 매질인 공기를 데우지 않으므로 이에 따른 열손실이 없이 열에너지가 전달되므로 85％정도의 높은 열 효율을 가진다.The near-infrared heat is not transferred by heat convection method, but heat is directly transmitted by radiant heat method by light energy. Therefore, heat energy is transferred without any heat loss. Has efficiency.

또한, 근적외선은 직접 투과되는 빛 에너지에 의해 열이 전달되어 베이스(41)에서 반사되며 코팅층(42)의 안에서부터 건조되어 나온다. 특히 근적외선의 파장에 수분 등이 직접 공진하며 즉시 배출되어 수초 내에 모든 건조가 이루어진다.In addition, near-infrared heat is transmitted by light energy transmitted directly, reflected from the base 41, and dried from the inside of the coating layer 42. In particular, moisture and the like directly resonate at the wavelength of the near infrared, and are immediately discharged, and all drying occurs within a few seconds.

따라서 베이스(41)가 열을 받는 시간이 짧아 얇은 필름과 같은 민감한 베이스(41)에도 사용이 가능하다.Accordingly, the base 41 may be short in heat and can be used for sensitive base 41 such as a thin film.

상기와 같은 건조장치는 열원(20)에 전원을 인가하게 되면 근적외선의 파장 이 피건조물(40)의 코팅층(42)을 가열 건조시킨다.In the drying apparatus as described above, when power is applied to the heat source 20, the wavelength of the near infrared ray is dried by heating the coating layer 42 of the object to be dried 40.

이때 열원(20)의 광이 반사판(12)에 반사된 후 코팅층(42)에 집광되어 건조속도를 향상시킨다.At this time, the light of the heat source 20 is reflected by the reflecting plate 12 and then concentrated on the coating layer 42 to improve the drying speed.

한편, 열원(20)에 의해서 가열된 케이스(10) 내부공간(11)으로 블로워(30)에 의해서 공급되는 공기는 가열되어서 열풍토출구멍(13)을 통하여 피건조물(40)의 코팅층(42)에 토출된다.On the other hand, the air supplied by the blower 30 to the inner space 11 of the case 10 heated by the heat source 20 is heated to the coating layer 42 of the object 40 through the hot air discharge hole 13 Is discharged to.

이때 토출되는 열풍에 의해서 코팅층(42)의 건조속도를 더욱 향상시키며, 또한 증발되는 코팅층(42)의 수분이 열원(20)측으로 상승되는 것을 차단하여 열원(20)이 오염되는 것을 방지시킨다.At this time, the drying speed of the coating layer 42 is further improved by the hot air discharged, and the moisture of the coating layer 42 to be evaporated is prevented from rising to the heat source 20 to prevent the heat source 20 from being contaminated.

즉, 열풍토출구멍(13)을 통하여 토출되는 열풍은 소위 '에어나이프(air knife;50)'를 형성하여 건조시키고자 하는 코팅층(42) 부분의 온도저하를 방지하면서 증발되는 수분등의 오염물이 열원(20)측으로 이동되는 것을 차단시킨다.That is, the hot air discharged through the hot air discharge hole 13 forms a so-called 'air knife 50' to prevent contaminants such as moisture evaporating while preventing the temperature drop of the portion of the coating layer 42 to be dried. It blocks the movement to the heat source 20 side.

상기와 같은 건조장치는 채용되는 열원(20) 즉, 근적외선의 파장 크기에 따라 피건조물(40)에 대해 적정한 속도로 상대이동시키면서 건조시킨다.The drying apparatus as described above is dried while moving relative to the dry object 40 at an appropriate speed according to the heat source 20 that is employed, that is, the wavelength of the near infrared rays.

또한, 상기 블로워(30)를 통한 공기는 냉풍 또는 온풍을 공급시킬 수 있다. 블로워(30)를 통하여 온풍을 공급시키는 것이 효율적이나 온풍 공급을 위하여는 다른 열원이 요구되므로 비효율적이다.In addition, the air through the blower 30 may supply cold air or warm air. It is efficient to supply the warm air through the blower 30, but it is inefficient because another heat source is required for the warm air supply.

본 발명 실시예에서는 블로워(30)를 통하여 냉풍을 공급시키더라도 가열된 케이스(10)에 의해서 가열되어 열풍이 공급되게 되므로 에너지효율을 높인다.In the exemplary embodiment of the present invention, even though the cold air is supplied through the blower 30, the heated air is supplied by the heated case 10 to supply the hot air, thereby increasing energy efficiency.
