It relates to a rotary low-temperature vacuum drying device for the remainder.
더욱이, 본 고안은 외부에서 유입되는 공기의 양을 조절하여 본체 내부의 유동을 형성하면서 내부의 대류를 극대화시켜 대류 열전달과 피건조물 표면 근방의 발생 수증기의 확산을 촉진함으로써 빠른 시간 내에 건조가 완료될 수 있도록 한잔반용 회전식 저온 감압 건조장치에 관한 것이다.Furthermore, the present invention controls the amount of air flowing in from the outside to form a flow inside the body while maximizing the convection inside, thereby promoting convective heat transfer and diffusion of generated water vapor near the surface of the object to be dried quickly. It is related with a rotary low-temperature vacuum drying apparatus for one and a half pieces.
일반적으로 우리나라에서 잔반 처리 및 산업폐기물의 건조를 주로 열풍건조에 의존하여 온 실정이다. 열풍 건조기는 보일러에서 700℃ ∼ 900℃ 상태로 발생한 연소열을 열교환기를 이용하여 80℃ ∼ 90℃ 상태로 가열하여 열풍 건조기내로 송풍하여 건조시키는 장치이다.In general, the residue treatment and drying of industrial waste in Korea has been mainly dependent on hot air drying.

도 2는 도 1의 본체 부분을 발췌하여 확대한 종단면도이다.2 is an enlarged longitudinal sectional view of the main body of FIG.
도시된 바와 같이, 본체(10)의 상면에는 덮개(12)가 형성되어 덮개를 닫은 상태에서 내부를 밀폐하여 임의로 정하는 진공 압력을 유지시킨다. 또한, 덮개(12)에는 감속모터(16)가 설치되고 감속모터(16)의 모터축(17)이 본체(10) 내부로 연장된다.As shown, the cover 12 is formed on the upper surface of the main body 10 to maintain the vacuum pressure that is arbitrarily determined by sealing the inside in a closed state.

이하, 상기와 같이 구성된 본 발명의 바람직한 작용효과를 첨부된 도면을 참조하여 설명하면 아래와 같다.Hereinafter, with reference to the accompanying drawings, preferred effects of the present invention configured as described above are as follows.
회전 블레이드(14)가 설치되어 있는 본체(10) 내부에 건조할 산업폐기물이나 잔반을 투입한다. 그리고, 피건조물에 공급할 열원을 가열하기 위한 열원공급장치인 보일러(20)와 히터(30)를 작동하여 열량을 공급한다.Industrial waste or residue to be dried is introduced into the main body 10 in which the rotary blades 14 are installed. Then, the boiler 20 and the heater 30, which are heat source supply devices for heating the heat source to be supplied to the dry item, are operated to supply heat.
또한, 본체(10) 내부의 진공을 형성하기 위해 수봉식 진공펌프(70)를 작동시켜 본체(10) 내부를 임의의 진공압력으로 유지한다. 즉, 건조로 인하여 생기는 발생 수증기와 외부로부터 본체에 지속적으로 유입하는 공기를 진공펌프(70)에 의해 본체(10)와 연결된 배관을 통하여 계속적으로 추출함에 따라 본체(10) 내부는 임의의 압력을 형성한다.In addition, the water-sealed vacuum pump 70 is operated to form a vacuum in the main body 10 to maintain the inside of the main body 10 at an arbitrary vacuum pressure. That is, by continuously extracting the water vapor generated due to drying and air flowing into the main body from the outside through the pipe connected to the main body 10 by the vacuum pump 70, the inside of the main body 10 receives a certain pressure. Form.
이어 피건조물의 신속하고 고른 건조를 위해 주파수제어에 의한 감속모터(16)를 작동시켜 회전 블레이드(14)를 작동하여 피건조물에 함유된 수분을 증발시킨다. 이때, 감압된 상태에서 증발이 이루어지므로 증발온도는 15℃ 전후로 유지할 수 있다.Subsequently, the speed reduction motor 16 by frequency control is operated to rapidly and evenly dry the dried object to operate the rotary blade 14 to evaporate the moisture contained in the dried product. At this time, since the evaporation is carried out in a reduced pressure state, the evaporation temperature can be maintained around 15 ℃.
증발된 수분은 열교환기(40)를 거치게 되는데, 바람직하게 열교환기(40)는 진공펌프(70)의 흡입 부하를 줄이기 위하여 진공펌프 배관 내부에 설치되어 냉동기(50)에서 얻은 저온열원과의 열교환을 통해 발생 수증기의 보유 열량이 냉각수로 이동함으로써 응축이 진행된다.The evaporated water is passed through a heat exchanger 40. Preferably, the heat exchanger 40 is installed inside the vacuum pump pipe to reduce the suction load of the vacuum pump 70 and exchanges heat with the low temperature heat source obtained from the freezer 50. Condensation proceeds by moving the retained heat of the generated steam to the cooling water through.
열교환기(40)에서 응축된 응축수는 열교환기(40)의 연직 하부의 집수탱크(60)에 고이게 된다.The condensed water condensed in the heat exchanger 40 accumulates in the collecting tank 60 at the vertical bottom of the heat exchanger 40.
이와 같이 건조장치의 본체 내부를 진공상태로 유지하면서 회전 블레이드의 회전을 통해 대류 및 물질확산을 촉진함으로써 건조에 소모되는 에너지를 최소화하고 신속한 건조를 실행하여 최종 함수율을 낮추는 회전식 저온 진공건조가 달성되는 것이다.In this way, by rotating the rotary blade while maintaining the inside of the main body of the drying apparatus to promote convection and material diffusion, rotary low temperature vacuum drying, which minimizes the energy consumed for drying and executes rapid drying, lowers the final moisture content. will be.
이상에서는 본 고안의 바람직한 실시예를 중심으로 설명하였지만, 본 고안의 정신을 벗어나지 않는 범위 내에서 다양한 변경이나 변형을 가할 수 있다. 따라서, 본 고안의 범위는 상기한 실시예에 국한되어서는 안되며, 이하에 서술되는 실용신안등록청구범위에 의해 결정되어야 한다.In the above described with reference to a preferred embodiment of the present invention, various changes or modifications can be made within the scope without departing from the spirit of the present invention. Therefore, the scope of the present invention should not be limited to the above embodiment, but should be determined by the utility model registration claims described below.
상기된 바와 같이 본 고안의 회전식 저온 감압 건조장치는 증발현상과 응축현상을 이용하는 소위 상변화 열전달의 응용으로써 열의 이동이 빨라 결과적으로 건조 소요시간이 단축되는 이점이 있다.As described above, the rotary low temperature decompression drying apparatus of the present invention has an advantage of shortening the time required for drying as a result of the rapid transfer of heat as an application of so-called phase change heat transfer using evaporation and condensation.
이에 따라, 에너지 소비량도 극소화되는 장점을 가지고 있으며, 건조시간의 단축으로 인하여 작업에 투여되는 인건비의 절감을 가져올 수 있다.Accordingly, the energy consumption is also minimized, and due to the shortening of the drying time, it is possible to bring down the labor cost to be administered to the work.
또한, 열풍건조시 발생되는 열풍의 고온으로 인해 건조 중에 발생할 수 악취 및 분진 발생이 전혀 없어 환경규제가 까다로운 외국으로의 수출도 용이하며, 국내에서도 산업폐기물의 매립이 엄격히 규제되어 가고 있는 시점에서 국내시장의 수요가 급격히 상승하게 될 수 있다는 이점이 있다.In addition, due to the high temperature of hot air generated during hot air drying, there are no odors and dusts that can occur during drying, and it is easy to export to foreign countries where environmental regulations are difficult.In Korea, when industrial waste is strictly regulated, The advantage is that market demand can rise sharply.
더욱이, 아파트나 식당에서 나오는 음식물 및 잔반의 처리시 악취발생억제와 신속한 처리, 에너지 절감으로 인한 운용비의 절감으로 음식물처리에 사용되는 비용을 최소화 할 수 있는 방법으로서 국가차원의 자원절약에 도움을 준다.Moreover, it helps to conserve national resources as a way of minimizing the cost used for food processing by suppressing bad odor when processing food and residues from apartments or restaurants and reducing the operating costs due to rapid treatment and energy saving. .
또한, 최저 함수율의 신속한 처리로 인해 에너지 비용이 절감됨에 따라 운영비용의 대폭적인 절감으로 산업용 폐기물 및 잔반처리 업체에 막대한 이익을 가져오게 될 수 있다.In addition, energy costs are reduced due to rapid disposal of the lowest water content, which can result in huge savings in industrial waste and residue treatment companies due to significant reductions in operating costs.
