본 발명은 탱크 속의 내용물을 가공하기 위하여 탱크의 내부를 진공상태로 만들거나 또는 탱크 내부에 높은 압력을 가하는 등의 탱크에 있어서, 탱크의 문짝을 개폐하는 구조를 개선하여 문짝 개폐에 필요한 공간을 최소화하고 탱크 내부에 내용물 넣거나 꺼내는 작업이 더욱 편리하도록 하며, 아울러 이러한 개선된 개폐구성에 적합하도록 문짝과 탱크 본체 간의 효율적인 밀폐구성을 제안한 것이다. The present invention minimizes the space required for opening and closing the door by improving the structure of opening and closing the door of the tank in the tank, such as making a vacuum inside the tank or applying a high pressure to the inside of the tank to process the contents in the tank. In addition, to make the operation of putting the contents in or out of the tank more convenient, and to fit the improved opening and closing configuration, the efficient sealing configuration between the door and the tank body is proposed.

주지된 바와 같이 각종 섬유제품을 가공하거나 고무제품을 가류하는 등의 용도로 사용되는 진공 또는 압력탱크는 탱크 본체에 내용물을 넣고 문짝을 닫아 밀폐한 후 진공 또는 고압상태에서 가공한 다음 문짝을 열고 내용물을 꺼내도록 된 것으로서, 큰 부피와 문짝을 개폐하는 구성에 높은 기밀성이 요구된다. As is well known, vacuum or pressure tanks, which are used for processing various textile products or vulcanizing rubber products, are filled in the tank body, closed by closing the door, processed in a vacuum or high pressure state, and then the door is opened. As it is to take out, high airtightness is calculated | required by the structure which opens and closes a big volume.

이러한 용도로 사용되는 기존의 진공 또는 압력탱크의 문짝 개폐구성을 보면, 탱크 본체의 아랫부분에 문짝방향으로 길게 레일을 깔아 문짝을 당겨서 열게 되는 서랍식 개폐장치와, 탱크 본체와 문짝을 경첩으로 연결하여 문짝을 당겨서 여는 방식이 대표적이다. In the door opening and closing configuration of a conventional vacuum or pressure tank used for this purpose, a drawer type opening and closing device is opened by pulling a door with a long rail in the lower part of the tank body, and the tank body and the door are connected by a hinge. Pulling the door open is typical.

이러한 종래의 탱크 중에서 서랍식 개폐방식은 문짝을 서랍처럼 당겨서 열어야 하는 특성상 탱크의 전방으로 작동시 넓고 긴 공간을 필요로 하게 되며, 탱크 본체에 내용물을 넣고 뺄 때도 내용물을 싣고 온 대차 등의 이동수단에서 문짝에 설치된 내용물 받침대로 내용물을 옮긴 다음 다시 문짝과 내용물을 탱크 본체로 밀 어 넣어야 하는 번거로움이 있다. The drawer-type opening / closing method among these conventional tanks requires a wide and long space when operating the front of the tank by pulling the door like a drawer to open it. There is a hassle to move the contents to the contents holder installed in the door and then push the door and contents back into the tank body.

또 다른 방식인 본체와 문짝을 경첩으로 연결하여 문짝을 당겨서 여는 방식은 탱크 본체에 넣기 위해 이동수단에 싣고 오던 내용물을 문짝이 열리기 위해 필요한 공간만큼 탱크 본체로부터 떨어진 거리에 대기시켜야 하고, 문짝을 열고나서 다시 내용물 받침대를 탱크 본체에 바짝 붙인 후에 내용물을 넣고 다시 이동수단이 후진한 다음 문짝을 닫아야 하며, 가공을 마치고 내용물을 꺼낼 때도 동일한 번거로움이 반복되는 것이었다. Another way of connecting the main body and the door with a hinge and pulling the door open is to wait at a distance from the tank body as much as necessary to open the contents loaded on the vehicle to open the door. Then, after attaching the contents cradle to the tank body again, the contents were put in, the moving means was retracted, the door was closed, and the door was closed. When the processing was finished and the contents were removed, the same hassle was repeated.

아울러 기존의 진공 또는 압력탱크의 개폐방식들은 본체와 문짝의 기밀유지를 위한 구성이 문짝을 닫은 다음 별도의 동작으로 밀폐를 하여야하므로 밀폐를 위한 작업에도 많이 시간이 소요되는 단점이 있었다.In addition, the opening and closing methods of the conventional vacuum or pressure tank had a disadvantage that it takes a lot of time for the sealing work because the configuration for the airtight maintenance of the main body and the door to close the door to be sealed by a separate operation.

상기한 문제점을 감안하여 안출한 본 발명은 탱크의 문짝이 개폐되는 방식이 마치 자동차의 윙도어 개폐방식처럼 탱크 일측에 설치된 작동중심축을 중심으로 문짝이 상부방향으로 열리게 개선하고자하는 것으로, 기존의 탱크의 문짝개폐방식이 가진 공간확보의 필요성과 내용물 출입시의 번거로움의 문제를 해소하고, 탱크 문짝이 닫힘과 동시에 밀폐작용이 이루어지고 문짝의 개방과 동시에 밀폐가 해제되도록 하는 등 밀폐에 관한 구성도 편리하게 개선함을 목적으로 하는 것이다. The present invention devised in view of the above problems is to improve the door to open the upper direction around the central axis of operation installed on one side of the tank as a way of opening and closing the door door of the car, the existing tank The configuration of sealing, such as eliminating the necessity of securing the space of the door opening and closing method and the hassle of entering and exiting the contents, closing the tank door and closing the door, and closing the door and opening the door at the same time. It is aimed at improving convenience.
