Description

소성로{Calcination Furnace}Calcination Furnace

본 발명은 소성로에 관한 것으로, 더욱 상세하게는 소성에 필요한 열에너지를 피소성물의 자체 열량을 활용하도록 함으로써 연료를 대폭 절감할 수 있는 소성로에 관한 것이다.The present invention relates to a kiln, and more particularly, to a kiln that can significantly reduce fuel by allowing the heat energy required for firing to utilize its own calories.

일반적으로 소성로는 로터리 건조기 타입이 대표적이다. 로터리 건조기의 구조는 내벽면에 내화벽돌이 부착된 눕혀진 원통형의 로와, 상기 로의 하부에 설치되어 로가 회전가능하도록 하는 롤러와, 로의 둘레에 설치된 링기어와, 상기 링기어를 회전 구동시키는 구동기어와, 로의 일측에 설치된 버너와, 버너의 반대쪽에 설치되어 연소가스를 배출시키는 배기수단과, 로의 일측에 설치되어 피소송물을 투입하는 투입수단과, 소성로의 내부를 이동하면서 소성된 소성물을 배출시키는 배출수단으로 구성된다.In general, the kiln is a rotary dryer type. The rotary dryer has a laid cylindrical furnace having a refractory brick attached to an inner wall thereof, a roller installed at a lower portion of the furnace to enable the furnace to rotate, a ring gear installed at the periphery of the furnace, and rotating the ring gear. A drive gear, a burner provided at one side of the furnace, an exhaust means provided at the opposite side of the burner to discharge combustion gas, an input means provided at one side of the furnace for injecting a litigation object, and a fired product that is fired while moving inside the kiln It is composed of a discharge means for discharging.

이러한 구성의 소성로는 버너가 점화되어 로의 내부를 고온으로 가열시면서 구동기어에 의해 링기어가 회전하여 로전체를 회전시킨 후 투입구를 통해 피소성물을 투입하면 회전하는 로내부 바닥에서 천천히 뒤섞이면서 연소열에 의해 배출수단 쪽으로 서서히 이동하면서 소성된다. 소성이 완료된 소성물은 배출수단을 통해배 출된다.The firing furnace of such a structure burns the burner and heats the inside of the furnace to a high temperature while the ring gear is rotated by the drive gear to rotate the whole furnace. It is fired while gradually moving toward the discharging means. The fired product is fired through the discharge means.

상기 구조의 소성로는 피소성물을 소성시키는 주 연소열을 버너에 의존하고 있다. 소성물의 자체열량을 가지고 있지만 지속적으로 회전하고 내부공간이 큰 로터리 건조기의 특성상 피소성물의 자체 열량을 활용하는 것은 어렵다.The kiln of the above structure relies on the burner for the main combustion heat for firing the to-be-fired material. It is difficult to utilize the calorific value of the calcined product due to the characteristics of the rotary dryer which has the calorific value of the calcined material but rotates continuously and has a large internal space.

물론 소성물에 따라 연료 소모량 차이가 약간 발생되는데, 피소성물에 열량이 많을 경우에는 자체 연소열을 통해 소성로의 연료절감에 약간의 도움을 줄 수 있으나 피소성물에 열량이 적을 경우에는 대부분의 열을 버너에 의존 할 수밖에 없는 등 상술한 기존 로터리 건조로 타입은 연료의 소모가 많은 단점이 있다. Of course, there is a slight difference in fuel consumption depending on the fired material. If the calcined material has a large amount of heat, self-combustion heat may help to save fuel in the kiln slightly, but when the calorie is low, most of the heat is burner. The conventional rotary drying furnace type described above has a disadvantage in that it consumes a lot of fuel.

아울러 소성이 완료된 소성물은 화분석 등과 같은 또다른 용도의 상품으로 재생산되는 것이기 때문에 제품의 원가 절감을 위해서는 반드시 소성로의 연료를 최소화할 수 있는 방안을 찾아 경제성을 높여야 할 것이다.In addition, since the calcined product is reproduced as a product for another use such as chemical analysis, it is necessary to find a way to minimize the fuel of the kiln to increase the economics in order to reduce the cost of the product.

본 발명은 상기와 같은 종래의 소성로의 단점을 해소하기 위해 창안한 것으로, 열량이 적은 소성물을 투입하더라도 소성물 자체의 연소열에 의해 소성로의 연료를 절감할 수 있도록 하여 소성로의 경제성을 대폭 향상시킬 수 있는 구조의 소성로를 제공하는데 그 목적이 있다.The present invention has been devised to solve the above disadvantages of the conventional kiln, and even if a caloric material having a low calorific value is added, the fuel of the kiln can be reduced by the heat of combustion of the kiln itself, thereby greatly improving the economics of the kiln. It is an object of the present invention to provide a kiln with a structure that can be used.

상기 목적을 달성하기 위한 본 발명은, The present invention for achieving the above object,

소성로 본체와, The kiln body and

상기 본체의 하부 둘레에 설치된 원형 레일과,A circular rail installed around the lower portion of the main body,

상기 원형레일 위에서 회전가능하게 설치되어 소성로의 바닥부를 구성하며, 중앙부에 배출구를 구비함과 동시에 상기 배출구를 향해 완만한 하향경사면을 이루는 회전테이블과,A rotary table rotatably installed on the circular rail to form a bottom portion of the kiln, and having a discharge port at the center thereof and a gentle downward slope toward the discharge hole;

외부에 설치되어 동력전달장치를 통해 상기 회전테이블을 저속으로 회전시키는 구동장치와,A drive device installed outside to rotate the rotary table at a low speed through a power transmission device;

상기 소성로 본체의 상부에 구비되어 피소성물을 상기 회전테이블의 측부로 투입하는 투입장치와,An input device which is provided at an upper portion of the firing furnace main body to inject a to-be-fired object to the side of the rotary table;

상기 회전테이블의 배출구 하부에 설치되어 소성된 소성물을 배출시키는 배출장치와,A discharge device installed under the discharge port of the rotary table to discharge the fired plastic product;

상기 소성로 내부의 회전테이블에 적층된 피소성물을 향하여 연소열을 가하는 버너와,A burner that applies combustion heat to the to-be-fired object laminated to the rotary table inside the firing furnace;

상기 소성로 본체 상부에 설치되어 배기가스를 배출시키는 배기장치로 구성됨을 특징으로 한다.It is characterized by consisting of an exhaust device which is installed on the top of the firing furnace body to discharge the exhaust gas.

본 발명 소성로는 투입된 피소성물이 회전테이블 중앙에 쌓인 상태로 연소되므로 내부에서 연소되는 피소성물의 연소열이 씨불이 되어 후속으로 투입되는 피소성물을 자체 연소열료 소성시키므로 열량이 적은 소성물이라 하더라도 자체 연소열로 소성시킬 수 있는 장점이 있다. 그리고 피소성물을 자체 연소열로 소성하므로 버너가 보조적 수단으로 활용됨에 따라 소성에 필요한 연료를 대폭 절감할 수 있는 효과가 있다.The firing furnace of the present invention burns the injected fired material in the center of the rotary table, so that the heat of burning of the fired fired material becomes a fire and subsequently fires the fired fired material by itself. There is an advantage that can be fired. In addition, since the burned material is fired by its own combustion heat, the burner is used as an auxiliary means, thereby greatly reducing the fuel required for firing.

도 1은 본 발명에 따른 소성로의 구조도이다.1 is a structural diagram of a kiln according to the present invention.

도시된 바와 같이 본 발명의 소성로는 직립 고정형 구조이다. 소성로 본체(10)는 원통형의 소성로가 직립된 구조이고, 필요에 따라 내벽에 내화벽돌(12)을 구성한다.As shown, the firing furnace of the present invention is an upright fixed structure. The kiln main body 10 has a structure in which a cylindrical kiln is erected, and forms the firebrick 12 in the inner wall as needed.

소성로 본체(10)의 내하부에는 회전테이블(20)이 장치되어 있다. 회전테이블(20)은 본체(10)의 하부 둘레에 고정설치된 원형의 레일(24) 위에 놓여져 레일(24)을 타고 회전가능하게 설치된다. 상기 회전테이블(20)은 중앙부를 향하여 완만한 경사면을 이루며, 중앙부에는 소성완료된 소성물을 배출시키는 배출구(22)가 형성되어 있다.The rotary table 20 is provided in the lower part of the kiln main body 10. The rotary table 20 is placed on the circular rail 24 fixed to the lower circumference of the main body 10 and rotatably installed on the rail 24. The rotary table 20 forms a gentle inclined surface toward the center portion, and a discharge port 22 for discharging the fired material is formed at the center portion.

그리고 상기 회전테이블(20)은 외부에 장치된 구동장치(26) 즉, 구동모터 및 이의 동력을 전달하는 동력전달장치와 연결되어 저속으로 회전하도록 구성된다.The rotary table 20 is configured to rotate at a low speed by being connected to an external drive device 26, that is, a drive motor and a power transmission device for transmitting power thereof.

본체(10)의 상부에는 회전테이블(20)의 가장자리를 향해 피소성물을 투입하는 투입장치(30)가 설치된다. 투입장치(30)는 연소가스의 역류가 방지되는 예를 들면 스크루컨베이어를 채용한다.In the upper portion of the main body 10 is an input device 30 for injecting the workpiece to the edge of the rotary table 20 is installed. The input device 30 employs, for example, a screw conveyor, in which back flow of combustion gas is prevented.

상기 회전테이블(20)의 하부에는 소성완료된 소성물을 배출시키는 배출장치(40)가 설치되는데, 이 또한 스크루컨베이어를 채용하는 것이 바람직하다. 소성로의 측부에는 버너(50)가 장치되며, 본체(10)의 상부에는 연소된 배기가스를 배출시키는 배기장치(60)가 설치된다.The lower part of the rotary table 20 is provided with a discharge device 40 for discharging the fired plastic products, it is also preferable to employ a screw conveyor. A burner 50 is installed at the side of the kiln, and an exhaust device 60 for discharging the burned exhaust gas is installed at the upper portion of the main body 10.

이러한 구성으로된 본 발명 소성로의 동작은 다음과 같다.The operation of the firing furnace of the present invention having such a configuration is as follows.

버너(50)가 작동하여 소성로의 내부온도를 상승시킴과 동시에 구동장치(26)를 가동하여 회전테이블(20)을 저속으로 회전시킨다.The burner 50 operates to raise the internal temperature of the kiln, and simultaneously operates the drive device 26 to rotate the rotary table 20 at a low speed.

이 상태에서 투입장치(30)를 통해 피소성물을 투입시키면 회전테이블(20)의 가장자리로 낙하하게 되고, 회전테이블(20)의 저속회전과 함께 화전테이블(20)의 완만한 경사면과 후속으로 투입되는 피소성물에 의해 선투입된 소성물은 서서히 회전테이블(20)의 중앙부로 이동하게 되며 결국 중앙부에 쌓이게 된다. 일정한 두께로 쌓여진 상태에서 피소성물은 지속적으로 연소되며 결국 어느 시점에서는 중앙부에 적층된 피소성물이 씨불형태로 연소된다. 도 1의 도면부호 'A'는 씨불영역을 표시한다. 이러한 씨불은 후속으로 투입되는 피소성물을 자체 발생온도로 연소시키게 되므로 버너(50) 없이도 소성이 이루어지게 된다. 즉, 버너(50)는 소성의 주기능이아니라 초기에 투입되는 피소성물을 자체 연소가 가능할 때까지 연소시키거나 연소되는 피소성물의 자체 연소열이 부족한 경우에만 간헐적으로 연소시키는 보조적 기능을 갖게 되는 것이다.In this state, when the object is introduced through the feeding device 30, the object is dropped to the edge of the rotating table 20, and the low speed rotation of the rotating table 20 causes the gentle slope of the hydrant table 20 and subsequent feeding. The fired product pre-injected by the to-be-fired material gradually moves to the center portion of the rotary table 20 and eventually accumulates at the center portion. In the state of being stacked in a constant thickness, the to-be-fired material is continuously burned, and at some point, the fired material stacked in the center portion is burned in the form of a sea fire. Reference numeral 'A' in FIG. 1 denotes a seed fire area. This seed fire is to be fired without the burner 50 because the subsequent fired material to be burned to its own generated temperature. That is, the burner 50 is not a main function of firing, but has an auxiliary function of burning an inert material initially input until the self-combustion is possible, or only intermittently burning if the self-heat of combustion of the incombustible material is insufficient. .

소성이 이루어지는 시간에 따라 회전테이블(20)의 배출구(22) 하부에 설치된 배출장치(40)를 동작시켜 소성완료된 소성물을 조금씩 배출시킨다. 이때 씨불상태를 온전히 유지할 정도의 속도로 배출시키는 것이 중요하다.In accordance with the time the firing is performed by operating the discharge device 40 installed in the outlet 22 of the rotary table 20 to discharge the burned plastic products little by little. At this time, it is important to discharge at a rate sufficient to keep the state of fire.

이와 같이 소성로 내부에서 피소성물이 씨불이 되어 투입되는 피소성물을 자체연소열로 소성시키게 되므로 적은 연료로도 피소성물의 소성이 가능하므로 소성 로의 연료를 대폭 절감할 수 있는 효과가 있다.In this way, since the fired material is fired by self-combustion of the fired material in the firing furnace, the fired fired material can be fired even with a small amount of fuel, thereby significantly reducing the fuel of the fired furnace.
