본 고안은 피건조물을 버너나 소각폐열의 열풍에 의해 간편 용이하게 건조시킬 수 있도록 한 직·간접 열풍건조기에 관한 것으로서, 특히 건조기본체의 내부하단에 히타엑스체인지(HEAT EXCHANGER)를 필요에 따라 설치 또는 제거하여 열풍을 직·간접적으로 겸용 사용토록하고, 병렬설치된 건조실마다 이송속도 및 교반속도를 달리하여 건조효율을 높일 수 있도록 한 것이다.The present invention relates to a direct and indirect hot air dryer that allows to easily dry a dry item by a burner or incineration waste heat. Especially, a heat exchanger is installed at the bottom of the drying base as needed. Alternatively, it is possible to use hot air directly or indirectly by removing it, and to increase drying efficiency by varying the feeding speed and the stirring speed for each drying chamber installed in parallel.
종래의 건조기는 건조실의 외벽을 가열하여 전도열에 의한 간접적인 열풍에 의한 간접열풍식과 건조기본체에 외부의 열원을 직접 불어넣어 직접적인 열풍에 의한 직접열풍식으로서 건조실의 피건조물을 이송, 교반하면서 건조시킬 수 있도록 하였다.The conventional dryer heats the outer wall of the drying chamber to indirect hot air by indirect hot air by conduction heat and directly blows external heat source to the drying main body, and direct dry air by direct hot air to transfer and stir dry items in the drying room. To make it possible.
그러나, 상기와 같은 직·간접적인 열풍식건조는 각각 별도의 단일품으로 제작되어 분리 형성되었기 때문에 유동적으로 겸용하는 것이 불가능하여 호환성이 없었을 뿐만 아니라, 건조실내의 피건조물 흐름이 일정한 속도로 이송되면서 건조되기 때문에 건조상태에 따른 건조 조건의 변화가 불가능하여 건조효율이 낮게되는 문제점이 지적되었다.However, since the direct and indirect hot air drying as described above is manufactured in a separate unit and formed separately, it is impossible to use it in a flexible manner, and there is no compatibility, and the dry matter flow in the drying chamber is transferred at a constant speed. It is pointed out that the drying efficiency is low because it is impossible to change the drying conditions according to the drying conditions.
또한, 건조효율을 높이고자 할 경우에는 건조기본체가 구체적으로 복잡하여 건조기가 비대해짐에 따라 결국 건조기 제작에 따른 코스트가 향상되는 문제점 등이 발생되었다.In addition, in order to increase the drying efficiency, the drying base is specifically complicated, and as the dryer becomes large, problems such as an increase in the cost of manufacturing the dryer have occurred.
본 고안은 상기한 종래의 문제점 등을 해결하기 위하여 안출한 것으로서, 필요에 따라 건조기 내부에 히타엑스체인지를 설치 또는 제거하므로 열풍을 직·간접식건조가 용이하도록 함은 물론 이로 인한 겸용사용의 호환성을 갖도록 함을 그 목적으로 하는 것이다.The present invention has been devised to solve the above-described problems, and as necessary, it installs or removes a heater exchange in the dryer to facilitate direct and indirect drying of hot air, as well as compatibility of the combined use thereof. It is to have a purpose.

상기 패들샤프트(11)의 중앙에는 회전축(12)이 구비되는 것으로 이 회전축(12)의 길이방향의 일정한 지점에는 사방으로 향하게 적어도 하나 이상의 지지바(13)가 구비되고, 이 지지바(13)에는 길이방향으로 긴 패들고정대(14)가 볼트로 고정되고 상기 패들고정대(14)의 외주연에는 나선방향으로 다수의 패들(15)이 경사지게 부착되어 구성된다. 한편 상기 패들샤프트(11)의 일측 회전축(12)에는 크기가 다른 소형스프로켓(16)과 대형스프로켓(17)이 체인(18)으로 연결되어 구성된다.At the center of the paddle shaft 11 is provided with a rotation shaft 12, at least a predetermined point in the longitudinal direction of the rotation shaft 12 is provided with at least one support bar 13 in all directions, the support bar 13 There is a long paddle holder 14 in the longitudinal direction is fixed with a bolt and a plurality of paddles 15 in a spiral direction is attached to the outer periphery of the paddle holder 14 is inclined. Meanwhile, the small sprocket 16 and the large sprocket 17 having different sizes are connected to one side of the shaft 12 of the paddle shaft 11 by a chain 18.
또한 상기 패들(15)은 부착각도를 최상단은 30°로서 절단기능을 높이도록 하고, 하단은 60°로서 교반기능을 높일 수 있도록 제작함이 바람직하나, 본 고안은 필요에 따라 패들(15)의 부착 각도를 조정할 수 있음은 물론이다.In addition, the paddle 15 is to increase the cutting function at the top of the attachment angle of 30 °, the lower end is preferably made to increase the stirring function as 60 °, the present design of the paddle 15 as needed Of course, the angle of attachment can be adjusted.
그리고 상기 건조기본체(1)의 내부 하단에는 외부공기유입구(23)가 구비되는 한편 일측적소에는 점검구(19)를 갖는 열교환실(20)이 형성되고 이 열교환실(20)에는 히타엑스체인지(21)를 삽입, 인출이 용이하도록 내장설치하고 전방에는 회전동력을 전달할 수 있는 메인모터(22)가 설치되어 구성된 것이다.In addition, an outer air inlet 23 is provided at an inner lower end of the drying base 1, while a heat exchange chamber 20 having an inspection opening 19 is formed at one side and a heat exchange chamber 20 is formed in the heat exchange chamber 20. ) Is built and installed to facilitate insertion and withdrawal, and the main motor 22 is installed in the front to transmit the rotational power.
이와같이 구성된 본 고안의 직간접 열풍건조기의 작용효과는 건조기본체(1)의 전면에 설치된 메인모터(22)가 구동되면 회전축(12)의 일측에 설치된 소형 스프로켓(16)과 대형스프로켓(17)이 체인(18)으로 연결되어 건조실(9)내의 패들샤프트(11)를 회전시킨다.The effect of the direct and indirect hot air dryer of the present invention configured as described above is that the small sprocket 16 and the large sprocket 17 installed on one side of the rotating shaft 12 are driven when the main motor 22 installed on the front of the drying main body 1 is driven. Connected to 18 to rotate the paddle shaft 11 in the drying chamber 9.
이때 메인모터(22)로부터 각 스프로켓(16)(17)을 거칠때마다 회전속도가 감소하여 건조기본체(1)의 최상단 패들샤프트(11)는 가장 낮은 회전속도로 구동되면서 가장 높은 토르크를 내고 최하단으로 갈수록 회전속도는 증가하고, 토르크는 감소하여 건조실(9)내의 건조조건 및 부하조건에 적합토록 회전이 용이하게 되는 것이다.At this time, each time the sprockets 16 and 17 pass from the main motor 22, the rotational speed decreases so that the uppermost paddle shaft 11 of the drying basic body 1 is driven at the lowest rotational speed to produce the highest torque and the lowest end. As the rotation speed increases, the torque decreases so that the rotation becomes easy to suit the drying conditions and load conditions in the drying chamber 9.
상기와 같이 구동되는 상태에서 피건조물은 단열재(2)가 충진된 건조기커버(3)로 이루어진 건조기본체(1)의 상면일측에 형성된 투입구(4)를 통하여 건조실(9)에 투입하면 메인모터(22)의 동력전달에 의해 회전되는 패들샤프트(11)의 패들(15)에 의해 교반, 분리 이송작용으로 건조가 진행되면서 축방향으로 이송 진행된다.In the driving state as described above, the dry matter is introduced into the drying chamber 9 through the inlet 4 formed on one side of the upper surface of the drying main body 1 including the dryer cover 3 filled with the heat insulating material 2.
