Description

액체보관용기{CONTAINER FOR STORING LIQUID MATERIAL}Liquid storage container {CONTAINER FOR STORING LIQUID MATERIAL}

본 발명은 내부의 액체를 완전히 배출시켜 새로 채워지는 액체의 순도를 유지할 수 있고, 액체의 배출을 정확히 제어할 수 있는 액체보관용기에 관한 것이다. The present invention relates to a liquid storage container capable of maintaining the purity of a newly filled liquid by completely discharging the liquid inside, and accurately controlling the discharge of the liquid.

철강소재를 개발할 때는 물성이나 조직 등을 다양한 형태로 분석한다. 물성이나 조직의 분석은 통상 투과전자현미경(TEM: Transmission Electron Microscope)과 같은 분석장치를 이용할 수 있다. 투과전자현미경은 전자빔을 집속시켜 시료에 조사하고, 시료를 투과한 전자빔을 전자렌즈로 확대하여 상을 얻는 방식으로 시료의 결정구조 등을 조사할 수 있다. When developing steel materials, physical properties and structures are analyzed in various forms. Analysis of physical properties and tissues may be performed using an analytical device such as a transmission electron microscope (TEM). The transmission electron microscope can investigate the crystal structure of the sample by focusing the electron beam and irradiating the sample, and expanding the electron beam transmitted through the sample with an electron lens to obtain an image.

이러한 분석장치로 시료를 분석할 때는 시료의 오염을 줄이고, 고배율, 고분해능, 미소영역 분석에 대한 효과를 높이기 위해 액체질소와 같은 용매를 연속적으로 공급한다. 통상 용매를 담은 보관용기를 분석장치의 인근에 비치하였다가 필요할 때마다 분석장치로 용매를 공급한다.When analyzing a sample with such an analysis device, a solvent such as liquid nitrogen is continuously supplied to reduce the contamination of the sample and increase the effect on high magnification, high resolution, and micro area analysis. Usually, the storage container containing the solvent is placed in the vicinity of the analyzer, and then the solvent is supplied to the analyzer whenever necessary.

그러나 종래 보관용기는 보관 용기 상부에 마련된 출구를 기울여 보관용기에 담긴 용매를 배출시키는 방식이기 때문에 보관용기 내에 담긴 용매를 완전히 배출시키기 어려운 형편이었다. 따라서 이러한 보관용기는 다시 새로운 용매를 채울 경우 내부에 잔존하는 용매로 인해 새로 채워진 용매의 순도를 유지하기 어려워 분석장치로 고순도 용매를 공급하기가 어려웠다. 또 이러한 보관용기는 용매의 배출을 정확히 제어하기 어려웠다. However, since the conventional storage container is a method of discharging the solvent contained in the storage container by tilting the outlet provided at the top of the storage container, it was difficult to completely discharge the solvent contained in the storage container. Therefore, it is difficult to supply a high-purity solvent to the analytical device because it is difficult to maintain the purity of the newly-filled solvent due to the solvent remaining therein when refilling the new solvent. In addition, it was difficult to accurately control the discharge of the solvent.

Can be. Restoration spring 90 may be composed of a tension coil spring is fixed to the upper side of the pressing member 20, one side is fixed to the upper side of the container body (10).

다음은 이러한 액체보관용기의 동작에 대해 설명한다.The following describes the operation of such a liquid storage container.

도 1에 도시한 바와 같이, 액체보관용기는 평소 용기본체(10)의 액체수용공간(14)에 액체가 채워진 상태에서 보관될 수 있다. 이 경우 액체배출밸브(31), 에어공급밸브(41), 에어배출밸브(51), 서브에어공급밸브(71)는 모두 폐쇄된 상태를 유지할 수 있다.As shown in FIG. 1, the liquid storage container may be stored in a state where the liquid is filled in the liquid receiving space 14 of the usual container body 10. In this case, the liquid discharge valve 31, the air supply valve 41, the air discharge valve 51, and the sub air supply valve 71 can all remain closed.

도 1의 상태에서 액체수용공간(14)의 액체를 용기본체(10) 외부로 배출시키고자 할 때는 작업자가 조작부(81)를 통해 설정량의 액체를 배출시키도록 제어부(80)에 지령할 수 있다. 그리고 제어부(80)는 동작지령을 토대로 에어공급밸브(41)와 액체배출밸브(31)를 개방하고, 에어배출밸브(51)를 폐쇄하도록 제어할 수 있다. In the state of FIG. 1, when the liquid in the liquid receiving space 14 is intended to be discharged to the outside of the container body 10, the operator may instruct the control unit 80 to discharge the liquid of the set amount through the operation unit 81. have. In addition, the controller 80 may control the air supply valve 41 and the liquid discharge valve 31 to be opened and the air discharge valve 51 to be closed based on the operation instruction.

액체를 배출시킬 때는 도 2에 도시한 바와 같이, 에어공급구(40)를 통해 상측의 빈 공간(13)으로 압축된 에어가 공급되고, 빈 공간(13)으로 공급된 에어가 가압부재(20)의 상면을 가압해 가압부재(20)를 하강시킨다. 따라서 액체수용공간(14)의 액체는 액체배출관(30)을 통해 외부로 배출될 수 있다. When discharging the liquid, as shown in FIG. 2, compressed air is supplied to the upper empty space 13 through the air supply port 40, and the air supplied to the empty space 13 is pressurized member 20 ) To press the upper surface of the pressing member 20 to descend. Therefore, the liquid in the liquid receiving space 14 may be discharged to the outside through the liquid discharge pipe 30.

액체가 배출되는 동안 제어부(80)는 승강센서(60)의 감지정보를 토대로 액체가 설정량 배출되었는지 여부를 판단할 수 있다. 따라서 작업자가 지령한 양만큼 액체가 배출되면, 제어부(80)는 액체배출밸브(31)와 에어공급밸브(41)를 폐쇄하도록 제어하여 액체의 배출이 멈추도록 할 수 있다. 즉 액체의 배출을 정확히 제어할 수 있다. While the liquid is being discharged, the control unit 80 may determine whether the liquid is discharged based on the detection information of the elevating sensor 60. Therefore, when the liquid is discharged by the amount instructed by the operator, the control unit 80 may control the liquid discharge valve 31 and the air supply valve 41 to be closed to stop the discharge of the liquid. That is, it is possible to accurately control the discharge of the liquid.

도 2에 도시한 바와 같이, 가압부재(20)가 용기본체(10)의 바닥까지 하강하면, 가압부재(20)의 액체가압면(24)이 하측용기부(11)의 바닥 내면에 밀착되므로 액체수용공간(14)의 액체는 모두 액체배출관(30)으로 배출될 수 있다. 2, when the pressing member 20 is lowered to the bottom of the container body 10, the liquid pressing surface 24 of the pressing member 20 is in close contact with the bottom inner surface of the lower container portion 11 All of the liquid in the liquid receiving space 14 may be discharged to the liquid discharge pipe 30.

제어부(80)는 도 2에 도시한 바와 같이, 가압부재(20)가 액체수용공간(14) 바닥까지 하강하면 서브에어공급밸브(71)를 개방하여 서브에어공급관(70)을 통해 액체배출관(30) 입구 쪽으로 에어가 공급되도록 할 수 있다. 따라서 이때는 도 3에 도시한 바와 같이, 서브에어공급관(70)을 통해 액체배출관(30) 내부로 에어가 공급되므로 액체배출관(30) 내에 잔존하는 액체까지 배출시킬 수 있다. 도 3처럼 액체배출관(30)의 액체를 배출시키는 과정에서 용기본체(10)를 기울이면 액체배출관(30)의 액체 배출이 더욱 원활해지므로 액체배출관(30)에 잔존하는 액체를 모두 배출시킬 수 있다.As shown in FIG. 2, the control unit 80 opens the sub air supply valve 71 when the pressing member 20 descends to the bottom of the liquid receiving space 14, thereby discharging the liquid through the sub air supply pipe 70 ( 30) Air can be supplied toward the inlet. Therefore, at this time, as shown in FIG. 3, since air is supplied into the liquid discharge pipe 30 through the sub-air supply pipe 70, it is possible to discharge the liquid remaining in the liquid discharge pipe 30. When the container body 10 is tilted in the process of discharging the liquid of the liquid discharge pipe 30 as shown in FIG. 3, the liquid discharge of the liquid discharge pipe 30 becomes smoother, so that all the remaining liquid in the liquid discharge pipe 30 can be discharged. have.

이처럼 본 실시 예의 액체보관용기는 용기본체(10) 내부의 액체를 완전히 배출시킬 수 있기 때문에 용기본체(10) 내부에 새로 채워지는 액체가 잔존 액체와 섞이는 것을 방지할 수 있어 액체의 순도를 유지할 수 있다.As described above, since the liquid storage container of the present embodiment can completely discharge the liquid inside the container body 10, it is possible to prevent the liquid newly filled in the container body 10 from mixing with the remaining liquid, thereby maintaining the purity of the liquid. have.

용기본체(10)의 액체수용공간(14)에 다시 새로운 액체를 채울 때는 도 4에 도시한 바와 같이, 역으로 액체배출관(30)을 통해 액체수용공간(14)으로 액체를 주입할 수 있다. 액체를 주입할 때 제어부(80)는 액체배출밸브(31)와 에어배출밸브(51)를 개방하고, 에어공급밸브(41)와 서브에어공급밸브(71)를 폐쇄하도록 제어할 수 있다. 따라서 이때는 액체수용공간(14)에 액체가 채워지면서 가압부재(20)가 상승하고, 빈 공간(13)의 공기가 에어배출구(50)를 통해 외부로 배출되므로 용기본체(10) 내에 액체를 쉽게 주입할 수 있다. When filling the liquid receiving space 14 of the container body 10 again with a new liquid, as shown in FIG. 4, it is possible to inject liquid into the liquid receiving space 14 through the liquid discharge pipe 30. When injecting the liquid, the control unit 80 may be controlled to open the liquid discharge valve 31 and the air discharge valve 51 and close the air supply valve 41 and the sub air supply valve 71. Therefore, at this time, as the liquid is filled in the liquid receiving space 14, the pressing member 20 rises, and the air in the empty space 13 is discharged to the outside through the air outlet 50, so that the liquid in the container body 10 is easily Can be injected
