본 고안은 고온의 열처리를 위한 로(爐)의 내부에 설치되는 전열히터용 애자구조에 관한 것이다.The present invention relates to an insulator structure for a heat transfer heater installed inside a furnace for high temperature heat treatment.
일반적으로 전열히터는 제3도에 도시한 바와 같이 다수의 애자가 직렬로 결합되고 이 애자의 니측둘레에 방사상으로 천공된 미도시된 관 통구를 통하여 전기저항을 갖는 열선이 가설된 구조를 이루고 있으며, 로의 내부 천정 및 양측벽에 설치된다.In general, as shown in FIG. 3, the electric heater has a structure in which a plurality of insulators are connected in series and a heating wire having electrical resistance is hypothesized through an unshown through-hole that is radially punched around the insulator's teeth. It is installed on the ceiling and both side walls of the furnace.
상기한 전열히터를 구성하는 애자는 절연성이 우수하고 고온에도 강한 재질인 세라믹재질로 형성된 것으로, 종래의 전열히터용 애자는 제 1도에 도시한 바와 같이 다수의 관통구가 내측둘레에 천공된 격판의 중싱상부에는 중심축이 형성되어 있고, 그 상단에 원형의 끼움돌기가 형성되어 다른 애자의 중심하부에 형성된 원형의 끼움홈에 상기 중심축의 끼움돌기가 요철결합되는 구조를 이루고 있었다.The insulator constituting the heat transfer heater is formed of a ceramic material having excellent insulation properties and high temperature resistance, and a conventional heat transfer heater insulator is formed with a plurality of through holes perforated in the inner circumference as shown in FIG. A central axis is formed in the upper middle portion of the, and a circular fitting protrusion is formed at the upper end thereof, thereby forming a structure in which the fitting protrusion of the central axis is unevenly coupled to the circular fitting groove formed at the lower center of the other insulator.
그런데 상기한 종래의 애자구조는 상호 직력로 다수개를 결합시킬 경우 각 애자의 격판둘레에 천공된 관통구가 일치되지 않고 어긋나게 됨으로써 결합시 관통구를 정렬시켜야 하는 불편이 있었으며, 사용중에도 관통구의 위치가 어긋나게 되는 페단이 있었다,However, in the conventional insulator structure, when the plurality of insulators are combined with each other, the through holes perforated on each insulator's diaphragm do not coincide with each other, so that the insulators have to be aligned. There was a pedan that went off,
본 고안은 상기한 종래의 불편과 폐단을 해소하기 위하여 안출된 것으로, 전열히터용 애자의 결합시 각 애자의 격판둘레에 천공된 관통구를 수작업으로 일일이 정렬시키지 않아도 되고, 사용주에도 상기 관통구의 위치가 흐트러지는 것을 방지함으로써 전열히터의 결합 및 사용할 때의 불편을 해소할 수 있는 수단을 제공하는 데 본 고안의 목적이 있는 것이다.The present invention is devised to solve the above-mentioned conventional inconveniences and discontinuities, it is not necessary to manually align the through-holes perforated on the perimeter of each insulator when the insulators for electric heaters are combined, and even the use of the through-holes It is an object of the present invention to provide a means that can eliminate the inconvenience of the combination and use of the electric heater by preventing the position is disturbed.
상기한 목적을 달성하기 위하여 본 고안은 상기 애자의 격판 중심상부에 형성된 중심축에는 그 상단에 사각형상의 끼움돌기를 형성시키고, 상기 애자의 격판 중심하부에는 상기 끼움돌기와 일치되도록 사각형상의 끼움홈을 형성시켜서 상호 결합시 상기 애자의 격판둘레에 형성된 관통구가 일렬로 정렬되도록 함으로써 애자의 결합시 각 애자의 격판둘레에 천공된 관통구를 수작업으로 일일이 정렬시키지 않아도 되고, 사용중에도 상기 관통구의 위치가 흐트러지는 것을 방지할 수 있도록 한 것이다.In order to achieve the above object, the present invention forms a rectangular fitting protrusion at an upper end of a center axis formed at the center of the diaphragm of the insulator, and a rectangular fitting groove is formed at the lower center of the diaphragm of the insulator to coincide with the fitting protrusion. In this case, the through holes formed on the insulator's diaphragm are aligned in a row so that the through holes perforated on the insulator's diaphragm are not manually aligned, and the positions of the through holes are uneven during use. It is to prevent losing.
이하 첩부된 도면에 의하여 본 고안을 더욱 상세히 설명하면 다음과 같다,Hereinafter, the present invention will be described in more detail with the accompanying drawings as follows.
제 2도는 본 고안에 의한 전열히터용 애자(10)를 예시한 것으로, 본 고안은 내측둘레에 다수의 관통구(12)가 천공된 격판(13)과, 이 격판(13)의 중심상부에 형성되고 그 상단에 사각형상의 끼움돌기(14)가 형성된 중심축(15), 상기 격판(13)의 중심하부에 상기 중심축(15)의 상단에 형성되는 끼움돌기(14)와 일치되도록 된 사각형상의 끼움홈(16)을 형성시킨 것을 특징으로하는 전열히터용 애자이다.2 illustrates the insulator 10 for the electric heater according to the present invention, and the present invention includes a diaphragm 13 having a plurality of through holes 12 perforated in an inner circumference thereof, and a central upper portion of the diaphragm 13. A central axis 15 formed at the upper end thereof and having a quadrangular fitting protrusion 14 formed thereon, and a quadrangular shape adapted to coincide with the fitting protrusion 14 formed at the upper end of the central axis 15 below the center of the diaphragm 13. Insulator for heat transfer heater, characterized in that the upper fitting groove 16 is formed.
제 2도에 도시한 바와 같이 본 고안에 의한 전열히터용 애자(10)는 중심축(15)의 상단에는 사각형상의 끼움돌기(14)가 형성되고, 격판(13)의 중심하부에는 상기 끼움돌기(14)와 일치되도록 사각형상의 끼움홈(16)을 형성시킴으로써 상호 결합시 상기 격판(13)에 천공된 관통구(12)의 위치가 스스로 정렬되게 되는 것이며, 본 고안에 의한 애자는 제 3도에 도시한 종래의 결합방식과 동일하게 다수의 애자(10)를 직렬로 결합시켜서 열선(1)을 상기 관통구(12)를 통하여 가설시켜서 사용하게 되는 것이다.As shown in FIG. 2, the heat heater insulator 10 according to the present invention has a rectangular fitting protrusion 14 formed at an upper end of the central axis 15, and the fitting protrusion below the center of the diaphragm 13. By forming the rectangular fitting groove 16 so as to coincide with (14), the position of the through hole 12 perforated in the diaphragm 13 is aligned with each other by itself, the insulator according to the present invention In the same manner as the conventional coupling method shown in the plurality of insulators 10 are connected in series to be used to install the heating wire 1 through the through-hole 12.
이상 설명한 바와 같이 본 고안에 의하면 애자의 격판 중심상부에 형성된 중심축에는 그 상단에 사각형상의 끼움돌기를 형성시키고, 상기 애자의 격판 중심하부에는 상기 끼움돌기와 일치되도록 사각형상의 끼움홈을 형성시켜서 상호결합시 상기 애자의 격판둘레에 형성된 관통구가 정렬되도록 함으로써 각 애자의 격판둘레에 천공된 관통구를 수작업으로 일일이 정력시키지 않아도 되고 스스로 정렬되게 되고, 사용중에도 상기 관통구의 위치가 흐트러지지 않게 되는 유용한 효과를 갖는다.As described above, according to the present invention, a square fitting protrusion is formed on the center axis formed on the center of the diaphragm of the insulator, and a square fitting groove is formed on the center of the diaphragm of the insulator to form a fitting groove. The through holes formed on the insulator's diaphragm are aligned so that the through holes perforated in the insulator's diaphragm do not need to be manually tweaked by hand, and are aligned by themselves, and the position of the through holes is not disturbed during use.
