Description

산소주입 및 누설 검사장치 {Oxygen injection and leak test apparatus} Oxygen injection and leak test apparatus {Oxygen injection and leak test apparatus}

본 발명은 산소주입 및 검사장치에 관한 것으로, 더 상세하게는 휴대용 산소저장용기의 용기본체와 캡조립체를 결합하고, 이 휴대용 산소저장용기에 산소를 주입한 후, 기밀상태를 검출할 수 있는 산소주입 및 누설 검사장치에 관한 것이다. The present invention relates to an oxygen injection and inspection apparatus, and more particularly, to combine a container body and a cap assembly of a portable oxygen storage container, inject oxygen into the portable oxygen storage container, and detect oxygen airtightness. It relates to injection and leak test equipment.

일반적으로 인체에 필요한 산소는 99.5%는 호흡을 통해서, 나머지 0.5%는 피부를 통해 공급받게 되며, 인체에 가장 적합한 산소농도는 대기중의 25%정도로 알려져 있지만, 도심지의 산소농도는 18-20% 정도로써 적정농도에 미치지 못하고 있다. 인체에 25% 내외의 산소가 포함된 맑은 공기가 공급될 경우, 대뇌활동을 촉진해 기억력과 집중력을 증진시키고 호흡기 및 순환계 환자의 증상 완화 및 신진대사를 촉진한다고 알려져 있다.In general, 99.5% of the oxygen required by the human body is supplied through respiration and the remaining 0.5% through the skin. As such, it does not reach the optimum concentration. It is known that when clean air containing around 25% oxygen is supplied to the human body, it promotes cerebral activity, improves memory and concentration, and relieves symptoms and promotes metabolism in respiratory and circulatory patients.

이러한 맑은 공기를 흡입할 수 있도록 하거나, 화재발생 시 대피자, 대피자용 방덕면, 또는 산소의 농도가 상대적으로 희박한 장소에서의 작업하는 작업자에게 산소를 공급할 수 있도록 휴대용 산소저장용기가 제공된다. A portable oxygen storage container is provided so that fresh air can be inhaled or oxygen can be supplied to an evacuee, a room for evacuees, or a worker working in a place where the concentration of oxygen is relatively low in the event of a fire.

이러한 휴대용 산소용기는 산소가 충전될 수 있도록 내부공간을 가지는 용기본체와, 용기본체의 상부측에 결합되어 용기본체 내부의 산소가 외부로 배출되도록하는 배출구와, 상기 배출구를 개폐하는 개폐부를 가지는 캡조립체로 구성된다. Such a portable oxygen container has a cap having a container body having an inner space so that oxygen can be filled, an outlet coupled to the upper side of the container body to allow oxygen inside the container body to be discharged to the outside, and an opening/closing portion that opens and closes the outlet. composed of assemblies.

대한민국 등록특허 제10-0827026호에는 휴대용 산소 발생장치가 게시되어 있으며, 대한민국 등록 실용신안 제 20-0485114호에는 휴대용 가스 충전장치가 게시되어 있다. Korean Patent Registration No. 10-0827026 discloses a portable oxygen generator, and Korean Utility Model Registration No. 20-0485114 discloses a portable gas filling device.

게시된 충전장치는 용기의 제작과 충전이 별개의 공정으로 이루어지므로 작업성이 떨어지고, 가스의 충전이 이루어진 후 누설상태를 검사할 수 없으므로 용기의 안전을 단보하기 어렵다. The posted charging device has poor workability because the manufacturing and filling of the container are performed in separate processes, and it is difficult to guarantee the safety of the container because the leakage state cannot be inspected after the gas is filled.

그리고, 대한민국 등록특허 제 10-1610523호에는 휴대용 완속충전기의 스파크 방지장치가 게시되어 있으며, 대한민국 등록특허 제 10-1971081호에는 산소충전장치가 게시되어 있다. In addition, Korean Patent Registration No. 10-1610523 discloses a portable slow charger spark prevention device, and Korean Patent Registration No. 10-1971081 discloses an oxygen charging device.

게시된 충전장치는 사각 박스형태로 이루어져, 내부에 다수개의 용기가 적층된 형태로 저장되는 용기저장트레이와, 용기의 상부에 설치되는 것으로, 주입구가 삽입되는 주입구삽입홈이 형성되고, 내부에 산소가 공급되어 용기의 내부에 산소를 충전하고, 밀봉하기 위한 산소충전수단을 포함한다The posted charging device is made in the form of a square box, a container storage tray in which a plurality of containers are stored in a stacked form, and an inlet insertion groove into which an inlet is inserted is formed, installed on the top of the container, and oxygen is supplied to fill the inside of the container with oxygen, and includes an oxygen filling means for sealing.

상술한 바와 같은 충전장치는 구조가 상대적으로 복잡하고, 다양한 규격의 산소저장용기의 소량생산에 적용하기 어렵다. The charging device as described above has a relatively complex structure and is difficult to apply to small-volume production of oxygen storage containers of various specifications.

상술한 바와 같이 구성된 본 발명에 따른 산소주입 및 누설검사장치의 작용을 설명하면 다음과 같다. The operation of the oxygen injection and leak test device according to the present invention configured as described above will be described as follows.

먼저, 산소주입 및 누설검사장치(10)을 이용하여 용기본체(110)과 캡조립체(120)를 결합하여 산소저장용기(100)를 완성하기 위해서는 상기 제1용기위치고정부(30)에 산소저장용기의 용기본체(110)를 위치시킨 후, 상기 용기본체(110)의 상부에 캡조립체(120)를 올려 놓는다. First, in order to complete the oxygen storage container 100 by combining the container body 110 and the cap assembly 120 using the oxygen injection and leak test device 10, the oxygen storage container 100 is attached to the first container position fixing part 30. After the container body 110 of the storage container is positioned, the cap assembly 120 is placed on top of the container body 110.

As described above, when gas filling is completed, a gas leak test of the oxygen storage container 100 is performed using the leak inspection unit 60 . In this leakage test, the oxygen storage container 100 into which oxygen is injected by the oxygen injection unit 40 is put into the detection container 62 where the detection fluid 61 is stored and submerged in the detection fluid 61.

이 상태에서 캡부재(65)를 상기 검출용기(62)와 결합하여 캡부재(65)에 지지된 가압부재(63)가 상기 검출유체(61)에 잠겨있는 산소저장용기(100)를 부상되지 않도록 한다. In this state, the cap member 65 is combined with the detection container 62 so that the pressure member 63 supported by the cap member 65 does not lift the oxygen storage container 100 submerged in the detection fluid 61. Avoid.

소정의 시간이 경과한 후 상기 기체펌프(66)를 작동시켜 상기 검출용기(62) 내의 기체를 상기 가스검출기(70) 측으로 펌핑하여 산소가스의 누설여부를 검출한다. After a predetermined time elapses, the gas pump 66 is operated to pump the gas in the detection container 62 toward the gas detector 70 to detect leakage of oxygen gas.

상술한 바와 같이 검출이 이루어지는 과정에서 또는 가스검출기(70)로부터 가스의 누설검출이 이루어지는 경우, 상기 산소저장용기(100)로부터 기포가 발생되는지 육안으로 정밀검사하여 누설이 이루어지는 산소저장용기(100)를 선별한다.As described above, in the process of detection or when gas leakage is detected from the gas detector 70, the oxygen storage container 100 in which leakage occurs by visually inspecting whether bubbles are generated from the oxygen storage container 100 select
