Description

밧데리용 음,양극의 극판 건조장치{a pole plate the drying equipment of cathode and anode for the battery}A pole plate the drying equipment of cathode and anode for the battery}

본 고안은 휴대폰이나 휴대용 전기, 전자제품 등에 전원을 공급하기 위하여 구비되는 밧데리용 음, 양극의 극판을 건조함에 있어서, 건조 대상체인 극판이 고주파 유도가열현상에 의한 급속 자기발열로 보다 신속한 건조는 물론 높은 수분제거효율을 득할 수 있도록 한 밧데리용 음, 양극의 극판 건조장치에 관한 것이다.The present invention is to dry the negative plate of the negative and positive electrode for the battery provided to supply power to mobile phones, portable electric, electronics, etc., as well as more rapid drying due to rapid self-heating by the high-frequency induction heating phenomenon The present invention relates to a negative electrode plate drying apparatus for negative and positive electrodes for batteries, which achieves high water removal efficiency.

일반적으로 휴대의 간편성을 도모하기 위한 전기, 전자제품이나 휴대폰 등에는 전원을 공급하기 위하여 충전용 밧데리를 설치하여 사용하고 있으며, 상기 밧데리에는 양, 음극의 극판을 설치하여 전기적 에너지가 발생하도록 되어 있고, 상기 극판은 밧데리의 구성에 따라 극판들 사이에 절연지를 게재시킨 상태에서 릴상으로 감아 구비하거나 판상으로 소정의 케이스안에 적층 구성된다.In general, electric, electronic products, mobile phones, etc., for the purpose of portability, are installed and used to supply power to the battery, and the battery is provided with the positive and negative pole plates to generate electrical energy. The pole plates may be provided in a reel shape or laminated in a predetermined case in a state of placing insulating paper between the pole plates according to the configuration of the battery.

이러한 양, 음극의 극판은 극판제조시의 건조상태에 따라 품질이 현저하게 달라질 수 있는데, 만일 극판에 수분이 함유되어 있을 경우 그 수분량에 따라 극성의 작용이 불량하게 되어 정격 에너지를 발생시키지 못하게 될 뿐 아니라 재충전상태가 불량하게 되어 밧데리의 수명이 현저히 짧아지는 문제점이 있다.These positive and negative pole plates may vary in quality depending on the dry state of the pole plate. If moisture is contained in the pole plates, the polarity will be poor depending on the amount of moisture, which will not generate rated energy. In addition, there is a problem that the life of the battery is significantly shortened because the recharge state is poor.

그러나 현재까지는 극판에 함유된 수분을 히터로 건조하였으므로 건조효율이 낮음은 물론 건조시간도 오래걸리는 문제점이 있었다.However, until now, since the moisture contained in the electrode plate was dried by a heater, there was a problem that the drying efficiency was low and the drying time was long.

즉, 히터를 이용한 극판 건조방식은 극판의 외면에서부터 내부까지 순차적으로 가열케하는 열전도 방식이어서 극판의 내부까지 열이 전도되는 시간이 길어지게 지게, 이에 따라 건조효율이 그 만큼 저하되게 되는 것이다.That is, the pole plate drying method using a heater is a heat conduction method that sequentially heats from the outer surface of the pole plate to the inside, so that the time for conducting heat to the inside of the pole plate becomes long, and thus the drying efficiency decreases by that much.

이를 상세히 설명하면 상기한 열전도 방식은 일정한 열매체(공기, 가스, 도체 등과 같은 열전도물)를 통하여 전달되는 것으로서, 그 매체의 전도율에 따라 많은 차가 있으나 분명한 것은 매우 느린 속도로 열 전달이 이루어질 뿐 아니라, 그렇다고 하여 고열을 순간적으로 가할 경우 피건조물의 제품손상(재질변형 등)이 발생할 수 밖에 없는 등 건조실시에 필요한 작업시간이 아주 오래걸리는 문제점이 있었다.In detail, the heat conduction method is transmitted through a constant heat medium (heat conductors such as air, gas, conductor, etc.), and there are many differences depending on the conductivity of the medium. However, there is a problem in that the work time required for drying is very long, such as product damage (material deformation, etc.) of the dried product may occur when instantaneously applying high heat.

이를 해결하기 위해 극판의 외측와 내측 양방향에서 동시에 열을 가한다 하더라도 열전도방식을 그대로 고수하는 한 추가되는 내측 열전달에 따른 상승효과 이외에는 더 이상의 건조효과는 기대할 수 없는 것이다.In order to solve this problem, even if heat is applied simultaneously in both the outer and inner sides of the electrode plate, further drying effects are not expected except for synergistic effects due to the additional inner heat transfer as long as the heat conduction method is adhered to as it is.

이러한 문제점은 밧데리용 음, 양극 극판의 생산성 및 품질향상을 저해하여 초정밀, 초소형, 최첨단 미래형 밧데리 개발을 더디게하는 원인으로 작용한다.This problem acts as a cause of slowing down the development of ultra-precision, ultra-small, and cutting-edge future batteries by inhibiting the improvement of productivity and quality of battery negative and positive electrode plates.

이에 본 고안에서는 건조효율에 한계점을 가지는 종래 열전도 건조방식과는 달리 피건조물인 극판의 급속 자기발열(유도가열)을 유도한 다음 그 열원으로 밧데리용 음, 양극의 극판이 가지는 수분을 신속하고도 효과적으로 제거/건조토록 함으로서, 보다 짧은 시간에 보다 높은 수분제거 효율을 얻을 수 있도록 하는 그 건조장치를 제공함에 주안점을 두고 본 고안을 완성한 것이다.Therefore, in the present design, unlike the conventional heat conduction drying method which has a limit in drying efficiency, it induces rapid self-heating (induction heating) of the electrode plate to be dried, and then, as the heat source, the moisture of the electrode plate of the negative and positive electrode for the battery is rapidly and By effectively removing / drying, the present invention has been completed, with the focus on providing the drying apparatus for obtaining a higher water removal efficiency in a shorter time.

위 기술적 과제를 달성하기 위하여 본 고안을 첨부된 각 도면에 의거 보다 상세히 설명하면 하기와 같다.In order to achieve the above technical problem, the present invention will be described in more detail based on the accompanying drawings.

극판(3)을 진공 건조기(A)의 건조실(A1)에 수납하여 건조하는 것에 있어서, 수납되는 극판(3)의 근접부에 고주파발생 수단을 설치하여 극판(3) 전체가 고주파에 노출될 수 있도록 하여서 된 것이고, 이를 실현하는 장치는 극판(3) 둘레로 다수개의 지지봉(2)을 원형으로 배치고정하고, 그 외주에는 고주파 전류가 유도되는 고주파발생 코일관(1)을 설치하여 극판(3)을 건조할 수 있도록 하며, 상기에서 고주파발생 코일관(1)은 그 단면을 원형 외의 사각형 등으로 하여도 무관하다.In storing the electrode plate 3 in the drying chamber A1 of the vacuum dryer A and drying the electrode plate 3, high frequency generating means may be provided in the vicinity of the electrode plate 3 to be housed so that the entire electrode plate 3 may be exposed to high frequency. The device for realizing this is to arrange and fix a plurality of supporting rods 2 in a circular shape around the pole plate 3, and to install a high frequency generating coil tube 1 through which a high frequency current is induced. ) Can be dried, and the high-frequency generating coil pipe 1 may have a square other than a circular cross section.

이와 같이된 본 고안은 극판(3) 건조장치가 종래와 같이 열전도에 의한 건조장치가 아니라, 고주파발생 코일관에 의한 고주파유도가열작용으로 극판(3) 전체를 가열토록 함으로써 극판(3)의 외면 및 내부 속까지 편차가 없는 균일한 열을 동시에 가할 수 있게 되어 극판(3)을 급속으로 건조할 수 있게 된다.The present invention as described above is not the drying device by the heat conduction as the conventional pole plate (3), but the outer surface of the pole plate (3) by heating the whole of the pole plate (3) by the high frequency induction heating action by the high frequency generating coil tube And it is possible to apply uniform heat without any deviation to the inner inside at the same time it is possible to rapidly dry the electrode plate (3).

상기에서 고주파 유도가열은 전자유도작용을 이용하여 상기 고주파발생 코일관에 교류전류를 흘러 교번자속이 발생하게 함으로써, 상기 극판(3)에 유도전류(와전류)가 흐르도록 하고, 이 유도전류는 와전류에 의해 주울열을 발생시키며 이렇게 발생된 열로 극판(3)을 가열해 수분제거 작용이 이루질 수 있도록 한 것이다.In the high frequency induction heating, an alternating magnetic flux is generated by flowing an alternating current through the high frequency generating coil tube by using an electromagnetic induction action, so that an induced current (eddy current) flows through the pole plate 3, and the induced current is an eddy current. It generates Joule heat by heating the pole plate (3) with the heat generated in this way to achieve the water removal action.

위와 같은 극판(3) 건조장치(고주파 유도가열건조법)는 열전도식인 종래 건조장치와는 비교할 수 없을 정도로 보다 효율적인 급속가열이 가능하기 때문에 극판(3)의 생산성을 높일 수 있게 되고, 또 건조작업도 획기적으로 향상/개선할 수 있게 된다.The pole plate (3) drying device (high frequency induction heating drying method) as described above can increase the productivity of the pole plate (3) because the rapid heating can be more efficient than the conventional drying device of the thermal conductivity type, and also the drying operation Significantly improve / improve.

그리고 극판(3)의 안전성이 높고, 그 발열시간 및 발열온도를 임의로 조절이 가능하기 때문에 다양한 시간과 온도조건하에서 건조를 실시할 수 있는 등 건조조건의 선택폭이 넓어지게 된다.In addition, since the safety of the pole plate 3 is high, and the heating time and the heating temperature can be arbitrarily adjusted, the selection of drying conditions becomes wider, such that drying can be performed under various time and temperature conditions.

이상과 같이 본 고안에서 제시하는 건조장치는 고주파전류를 이용하여 극판(3)의 외면은 물론 내부까지 동시에 침투가열(급속가열)할 수 있게 되어 열전도에 의한 종래의 건조방법에 비하여 건조시간이 획기적으로 단축될 수 있을 뿐만 아니라 보다 높은 수분제거효율로 인하여 우수한 품질의 극판(3)을 얻을 수 있게 되고, 나아가 고품질의 밧데리 생산에도 크게 일조할 수 있는 등의 간접적인 효과도 기대되는 것이다.As described above, the drying apparatus proposed in the present invention is capable of simultaneously infiltrating heating (rapid heating) not only to the outer surface of the electrode plate 3 but also to the inside by using a high frequency current, and thus the drying time is significantly lower than that of the conventional drying method by heat conduction. Not only can be shortened, but also due to the higher moisture removal efficiency can be obtained the pole plate (3) of excellent quality, and further indirect effects such as can greatly contribute to the production of high-quality batteries.
