본 발명은 피건조물을 버너나 소각폐열의 열풍에 의해 다량 건조시킬 수 있도록 한 다단 킬른(klin)식 직, 간접 화력건조기에 관한 것이다.The present invention relates to a multi-stage kiln-type, indirect thermal dryer, which allows to dry a large amount of dry matter by burner or incineration waste heat.
종래의 화력건조기는 1단의 건조드럼만을 회전되는 상태로 설치하여 피건조물을 이송교반하여 건조를 행하도록 구성되어 건조실내의 동일한 건조조건 또는 여백건조를 위한 체류시간을 주기 위해 건조실을 길게 제작하였다.Conventional thermal dryers are constructed so that only one stage of the drying drum is rotated so as to carry out drying by transporting and stirring the dried materials, and the drying chamber is made long to give the same drying conditions in the drying chamber or the residence time for margin drying. .
그러므로, 건조실의 노출면적이 커지게 되므로서 열손실이 과다하게 발생되어 건조효율이 낮아서 연료소모량이 과다하게 될 뿐만 아니라, 1개의 요건조드럼 내에서 동일한 속도로 피건조물을 이송하면서 건조하여야 하므로 건조조건 변화가 불가능하고, 용량에 비해 기계전체가 길어짐에 따라 설치공간 확보에 어려운 문제점 등이 야기되었다.Therefore, as the exposed area of the drying chamber becomes large, heat loss is excessively generated, and the drying efficiency is low, resulting in excessive fuel consumption, and drying by transporting the dry items at the same speed within one required drum. It is impossible to change the conditions, and as the whole machine becomes longer than the capacity, it is difficult to secure an installation space.
본 발명은 단열재로 된 건조본체내에 다단의 건조드럼(kiln)을 수직으로 지그재그로 경사지게 설치하여 콤팩트(compact)화 시켜 열풍체류시간을 길게 하면서 열손실을 최소화하려는 것과 피건조물의 건조진행에 따라서 적합한 건조조건을 부여토록 하여 건조효율을 높이고자 하려는 데 그 목적이 있다.The present invention is suitable for minimizing heat loss while prolonging the hot air residence time and compacting by installing a multi-stage drying drum (kiln) in a vertical zigzag inclined vertically in a drying body made of heat insulator. The purpose is to increase the drying efficiency by giving drying conditions.

제1도는 본 발명의 화력건조기를 설명하기 위한 개략단면예시도이다.1 is a schematic cross-sectional view illustrating the thermal dryer of the present invention.
제1도에서와 같이 단열재(2)로 된 건조기본체(10)의 내부에 건조드럼(3)을 지그재그로 경사지게 수직으로 다단설치하여 간접열풍유도판(4)으로 병열연결하고, 각 건조드럼(3)의 입구측에는 피건조물을 단계적으로 유도하기 위한 피건조물유도판(5)을 설치하며, 건조드럼(3) 하측에는 버너(7)가 설치된 연소실(6)을 형성하되, 이 연소실(6)의 내부에는 외부공기유입구(9)를 갖는 열교환기(8)를 설치하여 건조드럼(3)에 열풍이 공급되도록 접속연결한다.As shown in FIG. 1, the drying drum 3 is vertically installed in an inclined zigzag vertically in the interior of the drying base 10 made of the insulating material 2, connected in parallel with the indirect hot air induction plate 4, and each drying drum ( On the inlet side of 3), a dry guide plate 5 for guiding the dry matter is provided, and a combustion chamber 6 having a burner 7 is formed below the drying drum 3, but the combustion chamber 6 is provided. The heat exchanger (8) having an outside air inlet (9) is installed inside the connection to connect the hot air to the drying drum (3).
그리고 상기 경사진 건조드럼(3) 내부에는 샤프트(11)와 이격된 상태에 이송판(12)이 스크류 형식으로 부착된 패들본체(10)를 설치하되, 상기 샤프트(11)를 양측벽으로 관통설치하여 구동모터()14)에 의해 구동되는 스프로켓(13)과, 유니버셜조인트(15)로 접속연결하였다.In addition, a paddle body 10 having a screw plate attached to the conveying plate 12 in a state spaced apart from the shaft 11 is installed inside the inclined drying drum 3, and penetrates the shaft 11 through both side walls. The sprocket 13 driven by the drive motor 14 and the universal joint 15 were connected to each other.
이때 상기 구동모터(14)와 스프로켓(13)은 체인(16)으로 연결하되 스프로켓(13)은 상측에서 하측으로 갈수록 회전속도를 빠르게 하여 건조조건을 양호하게 부여토록 하고, 샤프트(11)와 스프로켓(13)은 베벨기어를 사용하여 동력을 전달하여도 된다.At this time, the drive motor 14 and the sprocket 13 are connected by a chain 16, but the sprocket 13 has a higher rotational speed from the upper side to the lower side to give a good dry condition, the shaft 11 and the sprocket (13) may use bevel gears to transmit power.
그리고 상기 상측의 건조드럼(3) 입구측 상측으론 투입스크류(18)가 설치된 투입구(17)를 설치하고, 상기 투입스크류(18)는 샤프트(11)의 회전동력과 체인(19)으로 연결하고 하측의 건조드럼(3) 끝단에는 로타리밸브(21)가 설치된 건조물배출구(20)를 설치하는 한편 건조기본체(1)의 상부중앙에는 개스배출구(22)를 설치하고, 투입구(17)의 하측에는 수중기 배출구(23)를 형성하였다.And the upper side of the drying drum (3) inlet side of the upper side is provided with an inlet (17) in which the inlet screw 18 is installed, the inlet screw 18 is connected to the rotational power of the shaft 11 and the chain (19) At the end of the drying drum 3 on the lower side, a drying outlet 20 having a rotary valve 21 is installed, while a gas outlet 22 is provided at the upper center of the drying base 1, and below the inlet 17. The submersible outlet 23 was formed.
이와 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.
본 발명은 콘트롤스위칭부(미도시함)에 의해 건조기를 작동코저 온시키면 구동모터(14)가 회전되어 건조드럼(3)을 회전시키게 되고 건조기 본체(1) 하측의 연소실(6)에는 버너(7)가 작동하여 가열하게 된다.According to the present invention, when the dryer is operated by a control switching unit (not shown), the driving motor 14 is rotated to rotate the drying drum 3, and a burner (3) is provided in the combustion chamber 6 below the dryer body 1. 7) is activated and heated.
건조기 본체(1)의 구동모터(14)의 회전작동으로 구동모터(14)와 체인(16)으로 연결된 각각의 스프로켓(13)을 회전시켜 건조기본체(1)내에 설치된 건조드럼(3) 내부의 패들본체(10)를 회전시킨다.Rotation operation of the drive motor 14 of the dryer main body 1 rotates each sprocket 13 connected by the drive motor 14 and the chain 16 so that the inside of the drying drum 3 installed in the drying base 1 can be rotated. Rotate the paddle body (10).
이때, 상측의 건조드럼(1) 내에 설치된 패들본체(10)의 회전력은 체인(19)에 의해 투입스크류(18)도 회전시키는 상태가 된다.At this time, the rotational force of the paddle body 10 installed in the upper drying drum 1 is in a state of rotating the injection screw 18 by the chain 19.
그리고, 하측의 연소실(6)에서는 버너(7)의 가열에 의해 열풍이 건조기본체(1) 내부를 지그재그로 순회하면서 개스배출구(2)로 방출토록 하고, 열교환기(8)이 열풍은 하측의 건조드럼(3)부터 내부로 거슬러 상측의 건조드럼(3)까지 역방향으로 통과하여 수중기배출구(23)로 방출하게 되는 것이다.In the combustion chamber 6 at the lower side, hot air is circulated in the drying main body 1 in a zig-zag by heating of the burner 7, and the heat exchanger 8 discharges the hot air at the lower side. From the drying drum (3) to the inside to pass through in the reverse direction to the drying drum (3) on the upper side is to be discharged to the water outlet (23).
이와 같이 작동되는 상태에서 단열재(2)로 된 건조기본체(1) 상부의 투입구(17)에 투입저장되는 피건조물은 투입스크류(18)에 의해 건조기본체(1) 내부에 수직으로 다단설치된 최상측의 건조드럼(3)에 투입된다.In the above-described operating state, the dry matter to be stored in the inlet 17 of the upper part of the drying base 1 made of the heat insulating material 2 is vertically installed in the drying body 1 vertically by the feeding screw 18. It is put into the drying drum (3).
이때 투입구(7)에서 투입스크류(18)에 의해 투입되는 피건조물은 입구측에 설치된 피건조물유도판(5)에 의해 외부로 비산됨 없이 건조드럼(3) 내부로 정확하게 투입된다.At this time, the to-be-dried product which is input by the injecting screw 18 in the inlet 7 is precisely fed into the drying drum 3 without being scattered to the outside by the dry guide plate 5 installed at the inlet side.
그리고 투입된 피건조물은 구동모터(14)의 회전력을 체인(16)에 의해 스프로켓(13)과, 유니버셜죠인트(15)를 거쳐 샤프트(11)에 의해 패들본체(10)의 회전으로 패들본체(10)에 스크류형상과 같이 부착된 이송판(12)이 돌아가면서 이송시켜 계단과 같은 다단식으로 설치된 다음 건조드럼(3)으로 이송시킨다.In addition, the put-to-be-dried product has the rotational force of the drive motor 14 by the chain 16 and the paddle body 10 by the rotation of the paddle body 10 by the shaft 11 via the sprocket 13 and the universal joint 15. The transfer plate 12 attached to the screw shape such as) is rotated and installed in a multistage manner such as a step, and then transferred to the drying drum 3.
이때 피건조물은 패들본체(10)의 회전중 중력에 의해 낙하하면서 건조드럼(3)의 기울어진 경사각만큼 이송이 진행됨과 동시에 피건조물이 건조드럼(3) 내부의 상측에서 하측으로 비산되면서 열교환기(8)에서 공급된 열풍과 접촉하여 건조가 진행된다.At this time, the dry item is dropped by gravity during rotation of the paddle body 10, and the transfer proceeds as much as the inclined angle of the drying drum 3, and the dry item is scattered from the upper side to the lower side of the drying drum 3, and then the heat exchanger. Drying advances in contact with the hot air supplied in (8).
그리고 계속해서 피건조물유도판(5)에 의해 건조드럼(3) 내부에서 지그재그로 진행되는 피건조물은 맨하측으로 건조드럼(3)으로 이송되어 로타리밸브(21)가 설치된 건조물배출구(20)로 배출되는 것이다.Subsequently, the dried material which is zigzag in the drying drum 3 by the dry goods guide plate 5 is transferred to the drying drum 3 to the lower side to the drying outlet 20 in which the rotary valve 21 is installed. It is discharged.
상기에서도 언급한 바와 같이 건조열풍은 버너(7)에 의해 열연소된 후 열교환기(8)의 관내부로 통과하여, 건조드럼(3) 외부로 유입되어 다단(지그재그)으로 거슬러 올라가면서 건조드럼(3) 외부를 가열시켜 내부에서 이송되는 피건조물을 건조시킨 후 개스배출구(22)를통해 대기중을 방출시킨다.As mentioned above, the drying hot air is thermally burned by the burner 7, passes through the inside of the heat exchanger 8, flows into the outside of the drying drum 3, and goes back to the multistage (zigzag). 3) The outside is heated to dry the dried material transported from the inside, and then the atmosphere is discharged through the gas outlet 22.
또한 건조기본체(1) 외부의 찬공기는 열교환기(8)에 외부공기유입구(9)를 통해 유입되면 이 공기가 열교환되어 가열되면서 간접열풍유도판(4)을 통해 하측의 건조드럼(3) 내부에 유입되어 피건조물의 이송경로와 역방향으로 거슬러 올라가면서, 피건조물과 직접 접촉되어 건조시키고, 증발된 수분을 함유하여 수증기배출구(23)를 통해 대기중으로 방출하여 건조를 촉진시킨다.In addition, when the cold air outside the drying base (1) flows into the heat exchanger (8) through the external air inlet (9), the air is heat-exchanged and heated, and the lower drying drum (3) through the indirect hot air induction plate (4). As it flows into the interior and goes back to the transfer path of the dry matter, it comes into direct contact with the dry matter and is dried. The vaporized water is released into the atmosphere through the water vapor outlet 23 to promote drying.
이때 상기 연소실(6)에 설치된 열교환기(8)를 제거할 경우, 연소개스를 직접 건조드럼(3) 내로 유입시켜 건조효율을 높일 수도 있고, 소각폐열을 공급받아 간접 열풍의 열원을 활용할 수도 있는 것이다.In this case, when the heat exchanger 8 installed in the combustion chamber 6 is removed, the combustion gas may be directly introduced into the drying drum 3 to increase drying efficiency, or incineration waste heat may be supplied to utilize a heat source of indirect hot air. will be.
이상 설명한 바와 같이 건조기 본체 내부의 건조드럼을 경사진 상태로 다단 설치하여 각 단계별로 회전수를 달리하여 피건조물을 이송건조시키므로서 고함수율에서 저함수율로 갈수록 회전수를 증가시키고, 외부를 단열시켜 건조진행에 따라 적합한 건조건이 부여하여 건조효과를 가일층 높일 수 있고, 외부로 방출되는 열손실을 극소화하도록 하는 한편 최소공간을 할용하도록 콤팩트한 구조로 설치 및 관리가 용이하며 직, 간접 열풍의 호환성을 갖도록 한 효과가 있다.As described above, by installing the drying drum inside the dryer body in an inclined state in multiple stages to transfer and dry the dried object by varying the rotational speed in each step, the rotational speed is increased from the high water content to the low water content, and the outside is insulated. According to the drying process, a suitable drying gun can be given to further increase the drying effect, minimize the heat loss emitted to the outside, and make it easy to install and manage with a compact structure to allocate the minimum space. Compatibility of direct and indirect hot air It is effective to have.
