본 발명은 주로 경유를 사용하여 열교환기에 의한 온방효과를 얻도록 하는 유류보일러에 있어서 동절기에 보일러를 가동시킬때 보다 원활하게 가동시켜줄 수 있도록 하기 위하여 유류를 예열시켜 주기 위한 예열장치에 관한 것으로서, 특히 송유되어지는 중간부에 설치할 수 있도록 된 것이다.The present invention relates to a preheating device for preheating the oil in order to be able to operate more smoothly when operating the boiler in winter in the oil boiler to obtain the warming effect by the heat exchanger mainly using diesel oil, in particular It can be installed in the middle of the oil.

주로 경유를 사용하는 유류보일러는 주로 주택의 온방용으로 사용하고 있으며, 근자에는 근교농업이 발달함에 따라 비닐하우스 또는 온실에서 각종 농작물 재배할때 겨울철에 비닐하우스와 온실을 난방시키기 위한 온풍장치에 장착하여 사용하고 있다.Oil boilers, which mainly use diesel oil, are mainly used for warming of houses.In recent years, as the suburban agriculture develops, they are installed in a warm air system to heat the plastic house and greenhouse in winter when growing various crops in a plastic house or greenhouse. I use it.

그런데 경유는 하절기에는 점도가 낮아져 이송과 펌핑이 용이하고 착화가 용이하나, 동절기에는 기온이 낮아질수록 점도가 높아져 이송과 펌핑이 용이치 못하고 착화하기도 용이치 못하다는 것이다.By the way, diesel has a low viscosity in summer, so it is easy to transport and pump, and easy to ignite, but in winter, the viscosity increases as the temperature decreases, making transport and pumping difficult and not easy to ignite.

특히 비닐하우스 또는 온실에서 재배되는 농작물에 온풍을 효과적으로 공급하지 못할 경우에는 큰 피해를 입게 된다.In particular, if the warm air is not effectively supplied to crops grown in a plastic house or greenhouse, a great damage will be caused.

따라서 유류보일러를 용이하게 가동시킬 수 있도록 하여주는 것이 바람직하며 본 발명에서는 유류보일러에서 경유를 버너에서 착화시키기 전에 미리 예열시켜줌으로서 점도가 높아져 있는 경유를 점도가 낮게 하여 주어서 보다 신속하게 착화시킬 수 있도록 하되, 예열시킬때 너무 높은 온도로 상승되지 못하도록 설정된 온도 이상으로 예열될 때에는 예열이 자동으로 중지되도록 하는 점진적으로 실시할 수 있도록 하는데 그 목적이 있다.Therefore, it is desirable to make the oil boiler easy to operate, and in the present invention, the oil oil having a high viscosity can be ignited more quickly by preheating the oil oil in advance before ignition in the burner. However, the purpose is to allow a gradual execution of the preheating is automatically stopped when preheating above the set temperature so as not to rise to too high temperature when preheating.

경유를 원료로 사용하고 있는 종래의 유류보일러는 예열장치가 구비되어 있지 않다.Conventional oil boilers using light oil as a raw material do not have a preheating device.

예열장치가 구비되어 있지 않더라도 기온이 다소 높은 하절기나 환절기에는 경유의 점도가 낮아 용이하게 보일러를 가동시킬 수 있으나, 동절기에는 점도가 높아져 용이하게 이송되지 못하고 따라서 펌핑능력도 현저히 떨어지며 특히 용이하게 점화할 수 없어 많은 애로사항을 느끼게 되는 문제점이 야기되었다.Even if it is not equipped with a preheating device, it is possible to operate the boiler easily due to the low viscosity of diesel in the summer or season when the temperature is high, but the viscosity is high so that the pumping capacity is not easily transferred. It caused a lot of problems that can not be felt.

위와 같은 문제를 해소할 수 있도록 된 것으로는 국내 실용신안 공개 제84-1672호가 알려져 있는데 이는 예열관에 히터를 내장시킨 것으로서, 주로 유류가 공급되는 송유관의 내부에 히터를 구비한 것이나, 히터를 송유관에 설치하기가 용이치 못하였다.It is known that the domestic utility model publication No. 84-1672 is known to solve the above problems, which is a built-in heater in the preheating pipe, which is mainly equipped with a heater in the oil supply pipe, or a heater It was not easy to install on.

본 발명은 이와 같은 문제점을 해소하고자 안출된 것으로서 이하 첨부도면에 의거 상세히 설명한다.The present invention will be described in detail based on the accompanying drawings as devised to solve such a problem.

제1도는 본 발명에 따른 일실시예의 예시도이다.1 is an illustration of one embodiment according to the present invention.

양측에 유입구(4)와 유출구(5)가 관통된 예열관(2)의 중간부에 예열실(3)을 형성하고 그 예열실(3)에 예열코일(6)을 내장하여 전원(8)을 연결하되 온도감지기(7)가 예열실(3)의 내부에서 예열을 감지하여 설정온도를 기준으로 ON, OFF되어지도록 된 것으로서, 예열실을 일정한 크기로 형성하여 줌으로써 용이하게 조립설치할 수 있다.The preheating chamber 3 is formed in the middle portion of the preheating tube 2 through which the inlet 4 and the outlet 5 are penetrated on both sides, and the preheating coil 6 is built in the preheating chamber 3 to supply the power source 8. The temperature sensor 7 detects preheating inside the preheating chamber 3 so as to be turned on and off based on the set temperature, and can be easily assembled and installed by forming a preheating chamber in a predetermined size.

이와 같이 구성된 본 발명의 예열장치(1)는 유류를 사용하는 보일러계통에서 버너의 전방송유관에 조립설치하여 주거나 송유관이 인입되는 버너의 전방부에 조립설치하여 주는 것이 바람직하다.The preheating apparatus 1 of the present invention configured as described above is preferably installed in an all-broadcast oil pipe of the burner in the boiler system using oil or installed in the front part of the burner into which the oil pipe is introduced.

송유관(도시하지 아니함)을 통하여 이송되던 유류가 유입구(4)를 통하여 예열실(3)에 유입되면 유류는 예열코일(6)의 발열에 의해 예열되기 전후 유출구(5)를 통하여 유출된 후 버너(도시하지 아니함)에 인입되던 버너를 가동시키게 된다.When the oil transported through the oil pipe (not shown) flows into the preheating chamber 3 through the inlet 4, the oil flows out through the outlet 5 before and after being preheated by the heat of the preheating coil 6, and then burner. (Not shown) will start the burner that was introduced.

예열코일(6)에서 발생된 열에 의해 예열실(3)의 유류가 예열될때 예열온도가 온도감지기(7)에 설정된 설정온도 이상으로 상승할 경우에는 온도감지기(7)가 이를 감지하여 자동 OFF되면서 전원(8)의 공급을 차단시켜 주게 되므로 예열코일(6)은 예열을 중단시키게 된다.When the oil in the preheating chamber 3 is preheated by the heat generated from the preheating coil 6, when the preheating temperature rises above the set temperature set in the temperature sensor 7, the temperature sensor 7 detects this and automatically turns off. Since the supply of the power supply 8 is interrupted, the preheating coil 6 stops preheating.

이와 같이 본 발명의 예열장치(1)는 동절기에 예열실(3)에서 유류를 예열시켜서 유류의 점도를 떨어뜨려 준후 이송과 펌핑을 용이하게 하여 주어 착화의 효율을 향상시켜주도록 함과 동시에 예열되는 유류가 너무 과열되는 것도 방지하여 예열장치(1)는 물론 버너가 과열되는 것을 예방할 수 있도록 하였다.As described above, the preheating apparatus 1 of the present invention preheats the oil in the preheating chamber 3 in the winter to reduce the viscosity of the oil, thereby facilitating transport and pumping, thereby improving the efficiency of ignition and being preheated. It was also possible to prevent the oil from overheating so as to prevent the preheater 1 as well as the burner from overheating.

제2도는 본 발명의 다른 실시예를 도시한 것으로서 예열관을 유입실(13)과 예열실(13-1)로 단차를 두고 형성하고 예열실(13-1)에 히터봉(16)을 삽착하여서 된 것이 특징이다.2 illustrates another embodiment of the present invention, in which a preheating tube is formed with an inflow chamber 13 and a preheating chamber 13-1 with a step difference, and a heater rod 16 is inserted into the preheating chamber 13-1. It is characterized by the work done.

유입구(4)를 통해 유입실(13)에 유입된 유류는 그 유입실(13)에서 예비 예열된 다음 예열실(13-1)에 인입되어 히터봉(16)의 예열에 의해 소정의 온도까지 예열되어진 후 유출구(5)를 통해 버너에 이송된다.The oil flowing into the inlet chamber 13 through the inlet 4 is preheated in the inlet chamber 13 and then introduced into the preheating chamber 13-1 to a predetermined temperature by preheating the heater rod 16. After being preheated, it is conveyed to the burner through the outlet 5.

히터봉(16)은 예열실(13-1)에 길게 인입되어 있기 때문에 유류가 히터봉(16)에 접촉하거나 근처를 통과할때 보다 효과적으로 예열시킬 수 있다.Since the heater rod 16 is long drawn in the preheating chamber 13-1, oil can be preheated more effectively when the oil contacts the heater rod 16 or passes through it.

또한 다른 실시예의 예열장치(10)도 예열온도가 설정온도 이상으로 상승할 경우 온도감지기(7)는 이를 감지하여 OFF되어 전원(8)이 히터봉(16)에 공급되는 것을 차단하여 예열을 중지하도록 함은 전술한 일예시 예열장치(1)와 동일하고 효과 역시 동일하다.In addition, when the preheating device 10 of another embodiment also increases the preheating temperature above the set temperature, the temperature sensor 7 detects this and turns off to stop the power supply 8 from being supplied to the heater rod 16 to stop the preheating. The same as in the above-described preheating device 1 in one example and the effect is the same.

이와 같이 본 발명에 따르면 유류보일러계통에서 유류를 버너에 공급하기전에 예열시켜 점도를 떨어뜨려서 이송과 펌핑 및 착화를 용이하게 하면서, 설정된 온도 이상으로 예열 상승될때에는 전원공급을 차단하여 예열을 일시적으로 중지하고, 개별적으로 유류예열장치를 제공함으로써 기존의 보일러에도 용이하게 조립설치할 수 있는 것이다.As described above, according to the present invention, the oil boiler system is preheated before supplying the oil to the burner, thereby reducing the viscosity, thereby facilitating transport, pumping and ignition. By stopping and providing oil preheaters individually, they can be easily assembled and installed in existing boilers.
