본 고안은 각종 가열용로나 축열용로의 노벽재에 관한 것으로, 특히 노내의 고온부와 노외측케이싱의 사이에 설치되어 고온부로부터 방출되는 열을 효과적으로 차단하는데 적합한 노벽(爐壁)용 단열패널 조립체에 관한 것이다.The present invention relates to a furnace wall material of various heating furnaces and heat storage furnaces, and more particularly to a furnace wall thermal insulation panel assembly suitable for effectively blocking heat emitted from a high temperature portion between a high temperature portion in a furnace and an outer casing. It is about.

일반적으로 축열용로나 소형전기로를 비롯한 요로(窯爐)등은 이들 노내부의 온도가 고온을 유지하게 되며, 이같이 고열이 노외부로 방출되어 열이 손실되는 것을 방지하기 위하여 고온부에 직접 노출되는 내화재나 축열재와 외부케이싱 사이에 단열재를 개재하여 열의 방출을 차단함과 아울러 외부케이싱이 가열되는 것을 방지하고 있다.In general, the temperature of these furnaces, such as heat storage furnaces and small electric furnaces, maintains high temperatures, and thus, a fire resistant material directly exposed to a high temperature part to prevent high heat from being released to the outside of the furnace. (B) A heat insulating material is interposed between the heat storage material and the outer casing to block the release of heat and to prevent the outer casing from being heated.

이같이 종래의 노벽 단열재로서 대표적인 형태로는 고온단열성능이 양호한 세라믹 재질의 세라믹 파이버 블랭킷(ceremic fiber blanket)을 들 수 있으며, 이같은 세라믹 파이버 블랭킷은 가요성 판상체 형태로서 실제 사용시에는 고온부의 온도에 따라 여러장이 겹쳐진 형태로 사용된다.As such a typical furnace wall insulation material, a ceramic fiber blanket made of a ceramic material having good high temperature insulation performance may be used. Such a ceramic fiber blanket is in the form of a flexible plate and according to the temperature of a high temperature part in actual use. Several sheets are used in an overlapped form.

그런데, 본 고안은 상기 종래의 세라믹 파이버 블랭킷 적층체는 그 자체가 상당한 두께를 지님에 따라 노벽두께의 증대 나아가서는 노자체의 대형화를 초래할 뿐만 아니라 가격면에서도 고가라는 문제점을 안고 있다.However, the present invention has a problem that the conventional ceramic fiber blanket laminate itself has a considerable thickness, thereby increasing the thickness of the furnace wall and thus increasing the size of the furnace body as well as being expensive in terms of price.

따라서, 본 고안은 상기 종래의 노벽용 단열재가 지니고 있는 제반 문제점을 감안하여 안출된 것으로, 세라믹 파이버 블랭킷의 외부케이싱측 표면에 금속재질의 골함석을 부착하여 효과적인 단열 및 단열벽 두께의 감소를 기한 노벽용 단열패널 조립체를 제공하고자 함에 고안의 목적이 있다.Therefore, the present invention was devised in view of all the problems of the conventional insulator for furnace walls, and it is possible to attach metal corrugated iron to the outer casing side surface of the ceramic fiber blanket to effectively insulate and reduce the thickness of the insulator wall. It is an object of the present invention to provide a wall insulation panel assembly.

특히, 본 고안은 노벽두께의 증대를 가져오는 세라믹 파이버 블랭킷의 다중적층을 피하기 위한 방편으로 일정두께의 세라믹 파이버 블랭킷의 케이싱측 표면에 파형(波形)골함석을 부착하여 세라믹 파이버 블랭킷과 외부케이싱 내면 사이에 형성된 공간부를 통과하는 열의 이동을 차단함에 특징이 있다.In particular, the present invention is a method for avoiding multiple stacking of ceramic fiber blankets, which leads to an increase in furnace wall thickness. It is characterized by blocking the movement of heat passing through the space portion formed in the.

이같은 본 고안의 구성을 첨부도면을 참조하여 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings the configuration of the present invention as follows.

먼저, 제1도는 본 고안의 일실시예에 대한 분해사시도로서, 도시된 바와같이 본 고안은 공지의 세라믹 파이버 블랭킷(1)을 사이에 두고 노의케이싱측 표면에는 금속재질의 골함석(2)이 그리고 반대편의 고온부측으로는 역시 금속제의 받침판(3)이 위치하여 이들 골함석(2)과 받침판(3)은 이들 각각의 내부에 형성된 구멍(1a)(2a)(3a)을 통하여 체결고정되는 고정구(4)에 의해 적층조립되어 노벽용 단열패널 조립체를 형성하게 된다.First, Figure 1 is an exploded perspective view of an embodiment of the present invention, as shown in the present invention is a bone metal (2) of the metal material on the casing side surface of the furnace with a known ceramic fiber blanket (1) in between On the opposite side of the high temperature part, a metal support plate 3 is also placed, and these bone irons 2 and the support plate 3 are fastened and fastened through holes 1a, 2a and 3a formed in their respective interiors. Laminated by 4) to form a thermal insulation panel assembly for the furnace wall.

미설명 부호 3b는 받침판(3)의 여러곳에 외측으로 엠보싱처리된 블록부이다.Reference numeral 3b denotes a block portion embossed outward at various places of the support plate 3.

이같은 구성으로 이루어진 본 고안의 일실시예를 축열용로에 설치한 상태를 보인 제2도 및 제3도에 의거 본 고안의 구조 및 특징으로 보다 상세히 설명하면 다음과 같다.When described in more detail with the structure and features of the present invention according to Figures 2 and 3 showing an embodiment of the present invention made in such a configuration installed in the heat storage furnace.

제2도는 축열용로(5)의 일부절결사시도이고, 제3도는 제2도의 A부 확대도로서 이에 도시된 바와같이 본 고나의 단열패널 조립체는 축열용로(5)의 고온부를 형성하는 축열재(6)와 외부케이싱(7) 사이의 공간부에 설치되며 이때 축열재(6)와 단열패널 조립체간에는 받침판(3)상에 돌출 형성된 볼록부(3b)의 높이만큼 간격부(t)가 형성되며 또한 반대편의 골함석(2)형성층과 외부케이싱(7)의 내면에 부착된 글라스울(glass wool)층 (8)과의 사이에도 일정한 공간부(T)가 형성된다.FIG. 2 is a partially cutaway perspective view of the heat storage furnace 5, and FIG. 3 is an enlarged view of a portion A of FIG. 2, and as shown therein, the heat insulation panel assembly of the present invention forms a high temperature portion of the heat storage furnace 5; It is installed in the space between the heat storage material 6 and the outer casing (7), wherein the space (t) between the heat storage material 6 and the heat insulating panel assembly by the height of the convex portion (3b) protruding on the support plate (3). Is formed, and a constant space portion T is also formed between the opposing bone tin (2) forming layer and the glass wool layer (8) attached to the inner surface of the outer casing (7).

이와같은 본 고안의 단열기구에 대해서 설명하면, 먼저 축열재(6)는 통상 650-700℃를 유지하며 이같은 고온부의 온도는 일차적으로 받침판(3)과 축열재(6) 표면과의 사이에 형성된 간격부(t)를 지나면서 점차 감소되기 시작하여 다중으로 중첩된 세라믹 파이버 블랭킷(1)을 지나면서 연속적으로 떨어지게 되고 다시 골함석(2)이 형성된 영역과 글라스울층(8)간의 공간부 (T)에서 급격히 저하되어 통상 외부케이싱(7)의 온도는 35-40℃를 나타내게 된다.Referring to the heat insulating mechanism of the present invention, first, the heat storage material 6 is usually maintained at 650-700 ℃ and the temperature of such a high temperature portion is formed primarily between the base plate 3 and the surface of the heat storage material (6). The space portion (T) between the glass wool layer (8) and the area in which the corrugated iron (2) is formed and is continuously dropped through the overlapping ceramic fiber blanket (1) begins to decrease gradually through the interval (t). At a sharp decrease in the temperature of the outer casing (7) is usually represented to 35-40 ℃.

본 고안에서 골함석(2)영역을 포함한 공간부(T)에서 온도가 급격히 떨어지는 이유를 열역학적으로 설명하면 다음과 같다.The reason why the temperature drops sharply in the space portion T including the bone tin (2) region in the present invention is as follows.

먼저, 전열현상의 세가지 기본기구중 하나인 열전도(heat condution)면에서 공간부(T)의 형성을 통해 열전달 매체를 제거하여 전도에 의한 열전달이 배제되는 한편으로 골함석(2)이 공간부(T)상에 개재되어 세라믹 파이버 블랭킷(1)으로부터 방출되는 열의 대류(heat convection)가 원활이 일어나지 못함은 물론 파상의 골함석(2)의 표면으로부터 방출되는 열복사(thermal radation) 역시 상쇄되어 공간부(T)에서 급격한 온도의 감소가 일어나게 된다.First, the heat transfer medium is eliminated through the formation of the space portion T in the heat condution plane, which is one of the three basic mechanisms of the heat transfer phenomenon, so that heat transfer by conduction is excluded, while the bone tin 2 is the space portion (T). ), Heat convection of heat emitted from the ceramic fiber blanket 1 is not smoothly generated, and thermal radation emitted from the surface of the corrugated bone stone 2 is also canceled so that the space T ), A sudden decrease in temperature occurs.

본 고안의 단열효과를 알아보기 위하여 본 고안이 설치된 노벽체와 종래의 세라믹 파이버 블랭킷 적층체가 설치된 경우의 벽체 각 지점에 대해서 열전대를 이용하여 온도를 측정하였던 바 그 결과는 제4도의 그래프에 나타나 있다.In order to examine the thermal insulation effect of the present invention, the temperature was measured by using a thermocouple at each point of the wall when the furnace wall and the conventional ceramic fiber blanket laminate were installed, and the results are shown in the graph of FIG. .

제4a도는 본 고안이 설치된 경우의 온도분포이고, 제4b도는 종래의 단열벽체의 온도분포로서 제4a도에서의 벽체 전체두께(t+4B+T)는 제4b도에서의 벽체두께(8B)보다 적다. 즉, t+4B+T〈8B이다(B는 단위 세라믹 파이버 블랭킷의 두께). 제4a도에서 알 수 있듯이 본 고안의 골함석을 포함하는 공간부(T)에서는 급격한 온도의 감소가 일어남에 따라 단열벽체의 증대를 초래하는 세라믹 파이버 블랭킷의 다중중첩을 최소화시키면서 만족할만한 단열효과를 거둘 수 있다.4a is a temperature distribution when the present invention is installed, and FIG. 4b is a temperature distribution of a conventional insulating wall, and the total wall thickness t + 4B + T in FIG. 4a is the wall thickness 8B in FIG. 4b. Less than That is, t + 4B + T <8B (B is the thickness of the unit ceramic fiber blanket). As can be seen in FIG. 4a, in the space portion T including the corrugated iron of the present invention, a satisfactory thermal insulation effect is achieved while minimizing multiple overlapping of the ceramic fiber blanket which causes an increase in the thermal insulation wall as a sudden decrease in temperature occurs. Can be.

이상에서 설명한 바와같이 본 고안은 단열벽체의 두께증대요인으로 작용하는 고가의 세라믹 파이버 블랭킷의 다중중첩을 최소화한채 구입이 용이하고 간단한 구조의 골함석을 이용한 단열판넬 조립체를 통해 우수한 단열효과를 발휘할 수 있는 효과가 있다.As described above, the present invention is easy to purchase while minimizing the multiple overlapping of expensive ceramic fiber blankets, which acts as an increase factor of the thickness of the insulation wall, and can exhibit excellent insulation effect through the insulation panel assembly using the corrugated iron of simple structure. It works.
