본 발명은 출원인이 발명한 특허 제19834호에서 석영관내부에 헬륨가스와 네온가스를 7 : 3 비율로 충진시켜 네온 가스에 의해 양쪽 전극에 빔을 형성시켜 헬륨가스의 분해 작용으로 고열을 발생시킬 수 있는 방전관에 있어서 석영관의 양측부를 봉합시켜 전극봉을 관내부에 삽입시켜 밀봉시키는 가공과정에서 3000℃ 고온의 수소용접으로 가공처리를 하므로 고온용접의 어려움과 폭발위험성으로 인해 석영관의 내경크기를 40mm 이상은 가공할 수가 없고 양 전극의 방전거리도 150mm일때의 빔의 상태가 가장 양호하므로 방전관의 직경과 길이가 한정되어서 있어서 그 내부의 헬륨량도 소량으로 한정되므로 12KW 전력소모시 발열온도가 300-400℃ 정도밖에 되지 못하므로 보일러와 같이 많은량의 발열량이 소요되는 경우 많은 숫자의 방전관을 설치하여야 되며 3000℃ 고온의 수소용접으로 가공처리하므로서 방전관의 대량생산이 어려워 제조단가의 상승요인이 되었다.According to the present invention, Patent No. 19834 invented by the applicant, helium gas and neon gas are filled in a 7: 3 ratio in the quartz tube to form beams on both electrodes by neon gas, thereby generating high heat by the decomposition of helium gas. In the discharge tube that can seal both sides of the quartz tube, the electrode rod is inserted into the tube and sealed, and processed by hydrogen welding at a high temperature of 3000 ° C. Therefore, the internal diameter of the quartz tube is reduced due to the difficulty of high temperature welding and the risk of explosion. It is impossible to process more than 40mm and the beam condition is best when the discharge distance of both electrodes is also 150mm. Therefore, the diameter and length of the discharge tube are limited, and the amount of helium inside is limited to a small amount. Since it is only about 400 ℃, if a large amount of heat is generated like a boiler, a large number of discharge tubes must be installed. The high temperature hydrogen welding at 00 ° C made it difficult to mass-produce the discharge tube, increasing the manufacturing cost.

본 발명에서는 이러한 석영관의 측부 봉합가공을 고온용접에 의하지 않고 내열온도가 1600℃ 이상되는 세라믹재질을 압측 금형에 의해 별개체의 세라믹측판을 성형하여 중앙돌출부의 관통공에 전극봉을 삽입시켜 가열로에 넣고 세라믹측판의 중심에 전극봉이 동일체가 되게 구워서 세라믹측판의 내곽에는 석영관을 그 외곽에는 스테인레스관을 각각 세라믹접착제로 부착시켜 조립에 의해 방전관을 구성하므로서 제조공정이 간편하고 방전관의 크기도 필요한 발열량에 맞게 임의대로 크게 제조할 수가 있는 것으로 도면에 의거 상세히 설명하면 다음과 같다.In the present invention, the side sealing processing of the quartz tube is not made by high temperature welding, but the ceramic material having a heat resistance temperature of 1600 ° C. or higher is formed by pressing the mold to form a separate ceramic side plate by inserting an electrode rod into the through hole of the central protrusion to heat the furnace. In the center of the ceramic side plate, the electrode rods are baked to be the same, and the quartz tube is attached to the inner side of the ceramic side plate, and the stainless steel tube is attached to the outside with a ceramic adhesive, so that the discharge tube is formed by assembling. According to the drawings in detail to be able to manufacture large according to the calorific value as follows.

일측면의 가장자리에 내, 외곽돌륜(11), (12)이 형성되고 양면 중앙에 전극돌출부(13), (14)가 형성되게 세라믹재질을 금형 압축으로 성형한 세라믹측판(10)을 전극돌출부의 중심에 삽입공(16)을 관통시켜 이에 선단에 12mm의 (14)가 형성된 직경 1mm의 몰리브덴강(molybdenum steel) 전극봉(3)을 삽입시켜서 가열로에 넣고 세라믹측판의 중심에 몰리브덴강의 전극봉이 고착되게 구운후 세라믹측판의 내, 외곽돌륜(11), (12)의 내곽에는 석영관(1)을 외곽에는 3mm 간격을 두고 스테인레스관(2)을 세라믹접착제(5)로서 부착시키고 세라믹측판의 일측에 1mm의 공기배출공(15)을 관통시켜 밀폐된 석영관 내부의 공기를 배출시킴과 동시에 7 : 3 비율로 혼합된 헬륨가스와 네온가스를 완전히 충진시키고 공기배출공을 세라믹접착제로서 밀봉시켜 된 것이다.The electrode protrusion part of the ceramic side plate 10 formed by molding the ceramic material by mold compression so that the inner and outer wheel wheels 11 and 12 are formed at the edge of one side and the electrode protrusions 13 and 14 are formed at the center of both sides. A molybdenum steel electrode (3) having a diameter of 1 mm having a 12 mm (14) formed at the tip thereof is inserted through the insertion hole 16 at the center thereof, and the electrode rod of molybdenum steel is placed in the center of the ceramic side plate. After being baked firmly, a quartz tube (1) is attached to the inner side of the ceramic side plate (11) and (12), and a stainless steel tube (2) is attached as the ceramic adhesive (5) at a distance of 3 mm to the outside. The air discharge hole 15 of 1mm is penetrated to one side to discharge the air inside the hermetically sealed quartz tube, and at the same time, the helium gas and the neon gas are completely filled in a 7: 3 ratio, and the air discharge hole is sealed with a ceramic adhesive. It is.

본 발명에서는 이와같이 종래처럼 석영관의 양측부를 밀봉시킴에 있어서 3000℃ 고온의 수소용접에 의하지 않고 내열온도가 높은 세라믹재질을 금형압축으로 성형하여 양면 중앙에 형성된 전극돌출부의 삽입공(16)에 몰리브덴강 전극봉(3)을 삽입시켜 세라믹측판과 동일체가 되게 구웠으므로 고온용접에 의한 취약점을 보완할 수가 있고 이렇게 구워진 세라믹측판의 내, 외곽돌륜(11), (12)에 내열온도가 1500℃ 이상인 세라믹접착체(5)로서 내곽에는 석영관(1)을 외곽에는 스테인레스관(2)을 조립식으로 부착켰으므로 종래처럼 석영관의 직경크기에 제한됨이 없이 필요용도에 따라 직경이 큰 방전관을 제조할 수가 있고 방전관 내부에도 많은량의 헬륨가스를 충진시킬 수가 있어서 800-1000℃ 고온의 발열량을 발산시킬 수가 있으며 석영관과 복사열이 가장 효과적으로 발생하도록 사이간격을 두고 그 외곽에 스테인레스관(2)을 부착시켰으므로 복사열의 효과도 얻을수가 있고 전체구성을 조립으로 제조하므로서 대량생산이 가능해지는 것이다.In the present invention as described above, in sealing both sides of the quartz tube as described above, the molybdenum is inserted into the insertion hole 16 formed at the center of both sides of the electrode protrusion formed by molding a ceramic material having a high heat resistance temperature by mold compression without using hydrogen welding at a high temperature of 3000 ° C. By inserting the steel electrode (3) to be the same as the ceramic side plate, it can be compensated for the weakness caused by high temperature welding, and the ceramic having a heat-resistant temperature of 1500 ℃ or more in the inner, outer wheel wheels (11), (12) of the baked ceramic side plate As the adhesive body 5, the quartz tube 1 is attached to the inner part and the stainless tube 2 is attached to the outer part in a prefabricated manner.
