원적외선 발열소자의 성형장치Molding apparatus for far infrared heating element

제1도는 본 고안의 완성된 사시도.1 is a completed perspective view of the present invention.

제2도는 본 고안의 완성된 단면도.2 is a completed cross-sectional view of the present invention.

제3도는 본 고안의 성형상태를 순차적으로 나타낸 단면도.Figure 3 is a cross-sectional view sequentially showing the molding state of the present invention.

본고안은 각종건조로에 사용되는 원적외선 발열소자의 성형장치에 관한것이다.This paper relates to a molding apparatus for far-infrared heating element used in various drying furnaces.

주지된 바와같이 원적외선 발열소자는 피건조물자체가 가지고 있는 고유의 적외선 흡수특성에 따라 해당 파장의 적외선을 방출시켜 조사하여야 하는바, 대개 건조용으로 사용되는 적외선 파장은 3정도 이상의 것을 요구하고 있으며, 그 재질로서 견고하고 절연성과 적외선파장이 양호한 마그네시아(Mgo) 및 그 화합물, 산화지루콘(ZrO2)아루미나 및 그 화합물 이산화규소(SiO2), 점토, 백로등을 적당비율로 혼합한 세라믹을 사용하는것이 바람직하다.As is well known, the far-infrared heating element should be irradiated by emitting infrared rays of the corresponding wavelengths according to the intrinsic infrared absorption characteristics of the object to be dried. In general, the infrared wavelength used for drying is 3 Magnesium (Mgo) and its compounds, Zirconium oxide (ZrO 2 ) alumina and its compounds silicon dioxide (SiO 2 ), clays, egrets, etc. It is preferable to use ceramics mixed in an appropriate ratio.

종래 원적외선 발열소자의 성형장치는 주로 일정형틀내에 반죽상의 세라믹 스립을 넣고 단번에 중공부가 형성된 완제품 형태로 성형하여 건조및 소성시킨후 그 외주연에 금속열선을 장치하거나 일정형틀내에 금속열선을 별도의 세라민 받침대 등으로 지지한다음 약간 묽은 세라믹을 부어 성형하였던 것으로서, 전자의 경우 금속열선이 외부로 노출되어 있기 때문에 적외선의 방열파장 영역이 좁아(예컨데 2이하) 그 용도가 한정적이었고 후자의 경우 금속열선이 세라믹몸체 내에 매몰되어있어 본고안과 유사한 효과를 얻을수는 있으나 성형시 금속열선을 별도의 세라믹 받침대등으로 받쳐주어야 함에따라 그 작업공정이 번거로워 생산가가 높아지는 요인이 되었으며, 특히 금속열선의 받침대가 죽상의 세라믹스립이 투입될때 유동할 우려가 많아 금속열선의 매몰깊이가 달라질 경우가 허다하였으며, 이로인해 균일한 성능의 제품을 얻을수가 없었다.Conventional molding apparatus of far-infrared heating element is mainly put dough-like ceramic slip in a mold, and molded into a finished product form in which hollow part is formed at once, and then dried and fired. It was formed by supporting it with a pedestal and then pouring a slightly thin ceramic. In the former case, since the metal heating wire is exposed to the outside, the infrared radiation wavelength region is narrow (e.g., 2 The use is limited and in the latter case, the metal heating wire is buried in the ceramic body, so that similar effect can be obtained in this case. In particular, there was a possibility that the base of the metal heating wire flows when the ceramic slip is introduced into the atherosclerosis, and thus the depth of burial of the metal heating wire is often changed. As a result, a product having a uniform performance cannot be obtained.

본고안은 이러한 종래의 문제점을 감안하여 보다 간단한 구조로서 양질의 발열소자를 양산할수 있도록 된 것으로 이를 첨부 도면에 의거 상세히 설명하면 다음과 같다.In view of this conventional problem, the present invention is capable of mass-producing a high-quality heating element with a simpler structure, which will be described in detail based on the accompanying drawings.

첨부도면에 있어서, 제1도 및 제2도는 본고안의 장치에 의하여 제작된 발열소자를 나타낸것으로, 1은 세라믹몸체(2)내에 매설된 금속열선인데, 이 세라믹몸체(2)의 외연에는 반사판(3)이 장설되어있다. 제3도는 본고안의 성형상태를 순차적으로 나타낸 것인데, 즉 제3(a)도는 상면에 적당형상의 요구(4)가 요설된 바닥형틀(5)위에 테형틀(6)를 재치한 것이다.In the accompanying drawings, FIGS. 1 and 2 show heat generating elements manufactured by the apparatus of the present invention, 1 is a metal heating wire embedded in the ceramic body 2, and the outer edge of the ceramic body 2 has a reflecting plate ( 3) It is laid. FIG. 3 shows the molding state of the present invention in sequence. In other words, in FIG. 3 (a), the mold 6 is placed on the bottom mold 5 in which the request 4 of suitable shape is arranged on the upper surface.

제3(b)도는 상기 제3(a)도 상태에서 내부에 세라믹스립(7)(예컨데 세라믹분을 물과 혼합하여 죽같이된 상태)을 투입시킨 상태를 나타낸 것이다.FIG. 3 (b) shows a state in which the ceramic slip 7 (for example, a state in which a ceramic powder is mixed with water in the form of porridge) is introduced in the third (a) state.

제3(c)도는 상기 제3(b)도 상태에서 일정시간을 경과시키면 세라믹스립(7)의 수분이 형틀(5)(6)내표면에 흡수되어 그 표면에 일정두께로 약간 굳게 되는데 이때 필요에 따라 미처 굳어지지않은 내측의 세라믹스립(7)을 외부 별도 용기에 따라 내면속이 비워진 상태로 된다.In FIG. 3 (c), when a predetermined time passes in the state of FIG. 3 (b), the moisture of the ceramic slip 7 is absorbed by the inner surface of the mold 5, 6 and slightly hardened to a predetermined thickness. If necessary, the inner surface of the ceramic slip 7 which is not hardened is emptied according to an external separate container.

제3(d)도는 상기 제3(c)도 상태에서 바닥형틀 (5)상면의 테형틀(6)를 제거하여 바닥형틀(5)에 바닥체만 남은 상태이다.3 (d) is a state in which only the bottom body remains in the bottom mold 5 by removing the frame 6 from the top of the bottom mold 5 in the third state (c).

제3(e)도는 상기 제3(d)도 상태에서 형성된 요홈(8)에 금속열선(1)을 배설한 상태를 나타낸 것이다.FIG. 3 (e) shows a state in which the metal heating wire 1 is disposed in the recess 8 formed in the third (d) state.

제3(f)도는 상기 제3(e)도 상태에서 바닥형틀(5)위에 마감형틀(10)를 재치한 상태이며, 제3(g)도는 상기 제3(f)도 상태에서 각형틀(5)(10)내에 세라믹스립(7)을 부어 넣은후 제3(c)도와 같은 방법으로 각형틀(5)(10)내표면의 굳은 부분을 제외한 세라믹스립(7)을 따라낼경우, 상체내부에 공간부(11)가 형성되게한 상태를 나타낸 것이다.FIG. 3 (f) is a state in which the finishing mold 10 is placed on the bottom mold 5 in the third (e) state, and FIG. 3 (g) is a rectangular mold in the third (f) state. 5) Pour the ceramic slip 7 into the (10) and pour out the ceramic slip (7) except for the hardened portion of the surface of the square frame (5) (10) in the same manner as in the third (c). It shows a state in which the space 11 is formed inside.

이와같이 구성되는 본고안의 성형상태를 설명하면 다음과같다. 즉, 제3(a)도와 같이 상면에 적당형상의 요구(4)가 요설된 바닥형틀 (5)위에 테형틀(6)을 재치한후 그내에 세라믹스립(7)을 부어넣는데, 이때 일정시간이 경과하면 세라믹스립(7)과 혼합된 수분이 각 형틀(5)(6)내표면에 흡수되면서 일정두께로 어느정도 굳게된다.The molding state of the present invention configured as described above is as follows. That is, as shown in FIG. 3 (a), the mold 6 is placed on the bottom mold 5 on which the desired shape 4 is arranged on the upper surface, and the ceramic slip 7 is poured therein. After this elapses, the moisture mixed with the ceramic slip 7 is absorbed by the inner surfaces of the molds 5 and 6, and is hardened to a certain thickness.

따라서 상기 형틀 (5)(6)의 내표면에 굳은 세라믹스립(7)을 제외한 내측의 굳지않은 세라믹스립(7)을 밖의 외부용기에 따라 주면 제3(c)와같이 바닥 형틀(5)의 요구(4)를 따라 요홈(8)이 형성된 바닥체가 남게되는데 이때 바닥형틀(5)의 상면 테형틀(6)를 제거하고 제3(e)도와 같이 상기 바닥체의 요홈(8)에 금속열선(1)을 배설한다.Therefore, if the inner hardened ceramic slip 7 except for the hardened ceramic slip 7 on the inner surface of the mold 5 and 6 is applied to the outer container, the bottom mold 5 may be removed as shown in 3c. A bottom body with grooves 8 formed along the demands 4 remains. At this time, the top frame 6 of the bottom mold 5 is removed and a metal heating wire is formed in the groove 8 of the bottom body as shown in FIG. Excrete (1).

금속열선(1)을 상기요홈(8)에 배설한후 바닥형틀 (5)상면에 마감형틀(10)을 제3(f)도와같이 재치하여 상기 제3(b)도, 제3(c)도와같은 방법으로 내부에 세라믹스립(7)을 투입하고 일정시간이 경과되면 형틀(5)(10)내표면에 바닥체와 상체가 일정두께로 완전일체화되어 굳어지는데 이때 그 굳어진 부분을 제외한 내측의 굳지않은 세라믹스립(7)을 밖으로 따라내면 내부에 공간부(11)가 형성되게되며, 필요에따라 세라믹몸체(2)내에 공간부(11)가 없도록 세라믹스립(7)을 충진시켜 밀폐할수도 있다.After the metal heating wire 1 is disposed in the groove 8, the finishing mold 10 is placed on the top of the bottom mold 5 as shown in FIG. 3 (f). In the same way as the ceramic slip (7) is introduced into the interior after a certain time, the bottom surface and the upper body on the surface of the mold (5) (10) is completely integrated to a certain thickness and hardened. When the stiff ceramic slip 7 is poured out, a space 11 is formed inside, and the ceramic slip 7 may be filled and sealed so that there is no space 11 in the ceramic body 2 as necessary. have.

이와같이하여 세라믹스립(7)이 적당히 굳어져 발열소자 형태가 완성이되면 탈형을 한후 이를 건조, 소성하여 제1도 및 제2도와같이 제품화 하는 것이다.In this way, when the ceramic slip 7 is appropriately hardened to form the heating element, the mold is demolded, dried, and fired to be commercialized as shown in FIGS. 1 and 2.

상술한 바와같이 본고안은 적당형상의 요구(4)가 요설된 바닥형틀 (5)상면에 세라믹스립(7)을 부워 바닥체를 구성하고 그 표면에 상기 요구(4)에 의한 요홈(8)이 형성되면, 이요홈(8)에 금속열선(1)을 배설하고, 이어 마감형틀(10)을 재치한후 마감형틀(10)내에 세라믹스립(7)을 유입시켜 상기 세라믹바닥체와 상체가 완전일체화되게함과 동시에 금속열선(1)이 매목되게 한것으로 제작공정이 비교적 간단하고 금속열선(1)을 균등하게 매몰시킬수 있어 생산가의 대폭인하와 균일한 성능을 가진 양질의 세라믹소자를 양산할수 있도록된 매우 유용하고 실용적인 고안이다.As described above, the present invention pours ceramic slips 7 on the upper surface of the bottom mold 5 in which the desired shape 4 is formed to form a bottom body, and the groove 8 according to the demand 4 on the surface thereof. After the formation, the metal heating wire 1 is disposed in the recess 8, and then the finishing mold 10 is placed, and then the ceramic slip 7 is introduced into the finishing mold 10 so that the ceramic bottom body and the upper body are formed. The metal heating wire (1) is buried at the same time as it is completely integrated, so the manufacturing process is relatively simple and the metal heating wire (1) can be evenly buried, so that it is possible to mass-produce high-quality ceramic elements with a significant reduction in production cost and uniform performance. It is a very useful and practical design.
