종래의 펠릿성형장치는 톱밥이나 일정 크기로 파쇄된 목재 칩을 이용하여 일정한 크기의 입상(펠릿) 형태로 연료를 성형하게 되는데, 연료를 성형하는 방식에 따라서 다양한 종류의 펠릿 성형장치가 개발되고 있다.Conventional pellet forming apparatus is used to shape the fuel in the form of granules (pellets) of a certain size using sawdust or crushed wood chips of a predetermined size, various types of pellet molding apparatus has been developed according to the method of forming the fuel. .
일반적으로 펠릿을 성형하기 위해서는 많은 조건이 필요하지만, 특히 중요한 조건으로 펠릿 성형 시 온도, 펠릿 성형용 원재료의 함수율, 생산되는 펠릿에 적합한 입자의 크기 등을 들 수 있으며, 이들 3가지의 중요한 조건이 적정하게 유지되어야만 품질 좋은 펠릿을 성형할 수 있다.In general, many conditions are required for molding pellets, but particularly important conditions include temperature during pellet molding, moisture content of raw materials for pellet molding, and particle size suitable for pellets produced. It must be kept in good shape to produce high quality pellets.
한편, 기존의 펠릿성형장치는 건조시설, 혼합시설, 성형시설 등 펠릿 성형 공정시 경유하게 되는 장치설비들이 거대하고, 상기 각각의 시설들이 분리 설치되어 있어 전체적으로 넓은 시설 공간을 차지하며, 이에 따라 시설비용이 많이 들어 개인 또는 중소 규모에서 소화하기에는 무리가 있어왔고, 펠릿성형장치의 대중화에 장애가 되어 왔다. 또한, 복잡한 장치설비로 인해 공정시간 또한 많이 소요되고, 펠릿 성형용 원료가 펠릿 제조 공정 중 체류하는 시간이 길어져 전체적으로 공정의 효율성이 떨어지는 문제가 있었다.On the other hand, the existing pellet molding apparatus is a large number of equipment facilities that pass through the pellet molding process, such as drying facilities, mixing facilities, molding facilities, each of the above facilities are installed separately occupies a large facility space as a whole, accordingly It has been expensive and difficult to digest on an individual or small scale, and has been an obstacle to the popularization of pellet molding equipment. In addition, due to the complex equipment, process time is also required a lot, and the time for the pellet forming raw material to stay in the pellet manufacturing process is long, there is a problem that the overall efficiency of the process decreases.
또한, 펠릿성형용 원재료가 2이상의 부산물 또는 폐기물일 경우, 각각 원재료의 함수율이 상이할 수 있는데, 기존의 펠릿성형장치는 이러한 원재료의 함수율 차이를 고려하고 있지 않고, 수분 함량의 많고 적음을 떠나 모두 한꺼번에 성형장치에 주입하여 가동하기 때문에 건조 공정의 효율이 떨어지며, 이는 불필요한 에너지 낭비 및 펠릿 제품의 질적 저하를 초래하는 문제로 이어져 왔다.In addition, when the raw material for pellet molding is two or more by-products or wastes, the moisture content of the raw materials may be different. However, the conventional pellet molding apparatus does not consider the difference in moisture content of these raw materials, but all of them have high and low moisture content. The efficiency of the drying process is reduced because it is injected and operated in a molding apparatus at once, which has led to problems of unnecessary waste of energy and quality of pellet products.

본 발명에서 상기 원료 주입구는 외부로부터 분말상의 각종 부산물 또는 폐기물 원료를 주입할 수 있도록 구비된 것으로, 사용자가 수분 함량이 각각 다른 분말상의 원료를 수분 함량 별로 분리 주입할 수 있도록 2 이상의 원료 주입구를 포함하고 있다. 본 발명에서 상기 분말상의 원료는 특별히 그 종류가 제한적인 것은 아니며, 커피찌꺼기, 폐목재, 축분, 볏짚, 쌀겨, 대나무, 콩대, 깻대, 한약재, 톱밥, 폐플라스틱 등 우리 주위에서 버려지는 거의 모든 부산물 또는 폐기물을 포함한다.In the present invention, the raw material inlet is provided to inject various powdered by-products or waste raw materials from the outside, and includes two or more raw material inlets so that the user can separately inject powdery raw materials having different moisture contents by water content. Doing. In the present invention, the powdery raw material is not particularly limited in its kind, and almost all by-products discarded around us, such as coffee grounds, waste wood, shavings, rice straw, rice bran, bamboo, soybean, daedae, herbs, sawdust, waste plastic Or waste.
본 발명에서 상기 건조기는 상기 원료 주입구와 연통되며, 상기 원료 주입구를 통해 내부로 유입되는 원료를 건조시키기 위해 구비된 것으로, 상기 건조기 내부의 일 영역에는 열풍건조기가 위치하고, 내부의 다른 일 영역에는 마이크로웨이브 건조기가 위치한다.In the present invention, the dryer is in communication with the raw material inlet, it is provided to dry the raw material introduced through the raw material inlet, the hot air dryer is located in one region inside the dryer, the other area inside the micro The wave dryer is located.
상기 열풍건조기는 상부 방향으로 일정압력의 열풍을 불어 넣어 주는 구조를 취하고 있는 것을 특징으로 하며, 이로 인해 상기 원료 주입구를 통해 건조기의 내부로 유입되는 분말상의 원료는 불어오는 열풍의 열에 의해 수분이 제거되면서, 동시에 상승하는 열풍의 압력에 의해 어느 정도 흩날리면서 혼합작용이 일어날 수 있게 된다. 즉, 별도의 혼합 장치 없이 건조와 혼합을 동시에 수행할 수 있는 이점이 있다. 따라서, 상기 열풍건조기는 보다 많은 원료를 수용하고 열풍에 의한 건조 및 혼합 효과를 극대화하기 위하여 건조기 내의 일 영역 중 최하부에 위치하는 것이 바람직할 수 있다.The hot air dryer is characterized in that it takes a structure that blows a hot air of a predetermined pressure in the upper direction, so that the powdery raw material flowing into the dryer through the raw material inlet is removed by the heat of the blowing hot air At the same time, the mixing action may occur while being blown to some extent by the pressure of the rising hot air. That is, there is an advantage in that drying and mixing can be performed simultaneously without a separate mixing device. Therefore, the hot air dryer may be located at the bottom of one region in the dryer in order to accommodate more raw material and maximize the drying and mixing effect by the hot air.
본 발명에서 상기 열풍건조기는 열풍의 압력 범위가 특별히 한정적인 것은 아니나, 열풍의 압력범위가 1 내지 10 bar인 것이 바람직하다. 이는 열풍의 압력이 1 bar 미만일 경우에는 열풍의 압력이 지나치게 약해 건조기 내부로 유입된 분말 상 원료의 혼합이 실질적으로 거의 일어나지 않고, 원료의 분말 입자들이 열풍건조기 내부로 낙하 및 침투하게 되어 열풍 건조기를 오염시키는 문제가 있으며, 반면 열풍의 압력이 10 bar를 초과하게 될 경우에는 열풍의 압력이 지나치게 높아 건조된 원료가 하부의 성형기로 잘 유입되지 않으며, 필요 이상으로 지나치게 많은 에너지를 소모하게 되는 문제가 있기 때문이다.In the present invention, the hot air dryer is not particularly limited in the pressure range of the hot air, it is preferable that the pressure range of the hot air is 1 to 10 bar. When the pressure of the hot air is less than 1 bar, the pressure of the hot air is so weak that substantially no mixing of powdery raw materials introduced into the dryer occurs, and powder particles of the raw material fall and penetrate into the hot air dryer, thereby On the other hand, if the pressure of the hot air exceeds 10 bar, the pressure of the hot air is so high that the dried raw material does not flow into the lower molding machine and consumes too much energy. Because there is.
또한, 상기 열풍건조기는 열풍의 온도 범위가 특별히 한정적인 것은 아니나, 열풍의 온도범위가 60 내지 150 ℃인 것이 바람직하다. 이는 열풍의 온도가 60 ℃ 미만일 경우에는 열풍의 온도가 지나치게 약해 건조기 내부로 유입된 분말 상 원료의 건조가 실질적으로 거의 일어나지 않는 문제가 있으며, 반면 열풍의 온도가 150 ℃를 초과하게 될 경우에는 열풍의 온도가 지나치게 높아 원료의 국부적 표면산화가 발생하여 원료 품질저하를 유발하게 되며, 필요 이상으로 지나치게 많은 에너지를 소모하게 되는 문제가 있기 때문이다.In addition, the hot air dryer is not particularly limited in the temperature range of the hot air, it is preferable that the temperature range of the hot air is 60 to 150 ℃. This is a problem that when the temperature of the hot air is less than 60 ℃, the temperature of the hot wind is too weak to substantially dry the powdery raw material introduced into the dryer, whereas when the temperature of the hot air exceeds 150 ℃ hot air This is because the temperature of is excessively high, which causes local surface oxidation of the raw material, causing the raw material quality to deteriorate and excessive energy consumption.
또한, 상기 열풍건조기는 내부 구조가 열풍을 발생시킬 수 있는 구조라면 어떠한 구조라도 무방하며, 일예로 열을 발생시키는 발열부(heater)와 발생된 열에 의해 온도가 상승한 공기를 건조기 내부로 불어 넣는 송풍기(fan)를 포함할 수 있으며, 나아가 발생되는 열풍의 온도를 제어할 수 있는 온도조절기를 더 포함하는 구조일 수 있다.In addition, the hot air dryer may have any structure as long as the internal structure is capable of generating hot air, and for example, a heater that generates heat and a blower that blows air whose temperature rises due to generated heat to the inside of the dryer. It may include a (fan), and may further have a structure further comprising a temperature controller for controlling the temperature of the generated hot air.
상기 열풍건조기의 건조기 내부를 향하는 상부면의 구조는 열풍을 상부로 토출할 수 있는 구조라면 어떠한 구조라도 가능하나, 적은 에너지로도 열풍의 압력을 충분히 원료의 혼합이 가능할 정도로 유지하면서, 건조기 내부 전체에 걸쳐 원료의 고른 혼합이 가능하게 하며, 분말상의 원료가 낙하하여 열풍건조기 내로 쉽게 유입되는 것을 방지하기 위해 구경 3 내지 20 mm의 토출공이 다수 형성되어 있는 구조를 취하는 것이 바람직하다.The structure of the upper surface of the hot air dryer facing the inside of the dryer may be any structure as long as it can discharge the hot air to the upper part, but the entire inside of the dryer may be maintained with sufficient energy to maintain the pressure of the hot air with little energy. It is preferable to take a structure in which a plurality of discharge holes having a diameter of 3 to 20 mm are formed in order to enable uniform mixing of the raw materials and to prevent the powdery raw materials from falling and easily flowing into the hot air dryer.
본 발명에서 상기 마이크로웨이브 건조기는 상기 원료 주입구 중 수분 함량이 일정 수준 이상인 원료가 주입되는 원료 주입구와 연결되어, 상기 원료를 건조기 내부로 유입시키기 전에 마이크로웨이브로 수분 함량을 일정 수준 이하로 낮추는 전 처리 구성으로서, 특히 열풍 건조기는 원료 입자에 함유된 수분 중 표면수는 잘 제거하나, 입자 내부 간극수는 잘 제거시키지 못하는 한계가 있는 반면, 상기 마이크로웨이브 건조기는 원료 입자의 표면수는 물론 내부 간극수까지 제거할 수 있는 이점이 있어, 본 발명에서는 수분함량의 정도가 다양한 부산물 또는 폐기물 원료를 건조시킴에 있어, 이를 구분 없이 모두 열풍 건조시키는 기존의 방식과는 달리 수분함량이 일정수준 이상으로 높은 고 수분 함량 원료에 대해서는 주입구를 구별하여 주입하도록 하고, 상기 주입되는 고 수분 함량 원료는 고 수분 함량 원료가 주입되는 주입구와 연결되어 있는 마이크로웨이브 건조기에 의해 원료 입자의 내부 간극수를 포함한 상당 부분의 수분이 제거될 수 있게 된다.In the present invention, the microwave dryer is connected to a raw material inlet which is injected with a raw material having a predetermined level or more of water content in the raw material inlet, and pretreatment to lower the water content to a predetermined level or less by microwave before introducing the raw material into the dryer. As a constitution, in particular, the hot air dryer removes the surface water in the water contained in the raw material particles well, but has a limitation in that it does not remove the internal pore water well, whereas the microwave dryer removes the surface water as well as the internal pore water of the raw material particles. In the present invention, in the present invention to dry various by-products or waste raw materials vary in degree of moisture content, unlike the conventional method of hot-air drying without any distinction, the water content is higher than a certain level high water content For the raw material, to distinguish the inlet And, a high water content in which the injected material is able to be a substantial portion of the water, including internal pore of the raw material particles by a microwave dryer, which is connected to the injection port is a high water content material injected removed.
본 발명에서 상기 마이크로웨이브 건조기는 건조시킬 대상 원료의 수분함량이 어느 정도이어야 하는지, 또한 상기 원료를 어느 정도까지 건조시켜야하는지에 대해서는 특별히 정해진 것은 없으나, 수분 함량이 40 % 이상인 원료가 건조기 내부로 유입되기 전에 마이크로웨이브로 수분 함량을 30 % 이하로 낮추는 것이 바람직하다. 이는 수분 함량이 40 % 미만인 원료를 마이크로웨이브를 이용하여 건조시키게 되면 굳이 열풍 건조만으로도 어느 정도 고른 건조가 가능함에도 불필요한 에너지 소모가 발생하고, 마이크로웨이브로 별도 건조하는 실익이 거의 없게 되는 문제가 있으며, 상기 마이크로웨이브 건조기로 건조시킨 원료의 수분함량이 30 %를 초과할 경우에는 이후 건조기 내의 다른 원료와 혼합되었을 때 건조기 내 전체적으로 고른 건조가 잘 이루어지지 않는 문제가 있기 때문이다. In the present invention, the microwave dryer is not particularly determined how much the moisture content of the raw material to be dried and to what extent the raw material should be dried, but the raw material having a moisture content of 40% or more is introduced into the dryer. It is desirable to reduce the moisture content to 30% or less with microwaves before the process. This is a problem that if the raw material having a moisture content of less than 40% is dried using microwaves, even though it is possible to dry evenly only by hot air drying, unnecessary energy consumption occurs, and there is almost no benefit to separate drying with microwaves. If the moisture content of the raw material dried by the microwave dryer exceeds 30% is because there is a problem that evenly dried in the dryer as a whole when mixed with other raw materials in the dryer.
본 발명에서 상기 성형기는 건조기로부터 배출되는 건조된 분말상의 원료를 펠릿 형상으로 성형하는 구성으로서, 상기 성형기의 종류나 타입은 특별히 제한적인 것은 아니며, 통상적으로 펠릿 성형에 사용되는 성형기라면 어떠한 성형기라도 무방하다. 본 발명의 일 실시예에서는 다수의 관통공이 형성되어 있고 일정 두께를 가진 원반 형태로서, 수평 회전 운동을 하는 다이(die) 및 상기 다이(die)의 윗면에 밀착 형성되고 상기 다이(die)가 회전할 때 그 마찰력에 의해 맞물려서 회전하는 롤러(roller)를 포함하는 성형기를 사용하고 있다. 이와 같은 성형기를 사용할 경우, 상기 건조기는 또 다른 일 영역에 구동축이 건조기를 통과하여 성형기의 다이(die)의 중심부와 결합되어 있어 상기 다이(die)가 회전할 때 함께 회전할 수 있는 교반기가 더 위치할 수 도 있다. 이렇게 되면, 상기 성형기의 다이(die)가 회전할 때 상기 교반기도 함께 회전하게 되어, 상기 건조기 내의 원료를 보다 효과적으로 혼합할 수 있는 이점이 있다.In the present invention, the molding machine is configured to form the dried powdery raw material discharged from the dryer into pellets, and the type or type of the molding machine is not particularly limited, and any molding machine may be used as long as the molding machine is usually used for pellet molding.
