본 고안의 브라운관의 스크린공정에 사용되는 불산의 회수처리와 관련된 불산회수탱크의 개선에 관한 것으로, 특히 탱크내부의 침전된 이물들을 자동으로 용이하게 제거할 수 있도록 하는데에 주안점을 두어 안출한 것이다.The present invention relates to the improvement of the hydrofluoric acid recovery tank related to the recovery of hydrofluoric acid used in the screening process of the CRT of the present invention. In particular, the present invention focuses on easily and easily removing precipitated foreign matter in the tank.

브라운관의 스크린공정에 있어서는 세척전처리하기 위해 다량의 불산이 사용되는데, 판넬내면을 세척하고 난 사용 불산은 적정의 회수탱크로 회수되어 여기에서 그에 섞인 이물들이 침전제거되고, 이물들이 침전제거된 깨끗한 불산이 다시 사용처로 공급사용되는 사이클을 반복순환하게 된다.In the screening process of CRT, a large amount of hydrofluoric acid is used to pretreat the washing. The hydrofluoric acid after washing the inner surface of the panel is recovered to a proper recovery tank, where the foreign substances mixed therewith are precipitated and the foreign substances are precipitated and cleaned. This cycle is repeated in the cycle of supply and use.

제1도는 위와 같은 용도로 설치사용되어 왔던 종래의 불산회수탱크 구성개요를 보여주는 단면도인데, 이 종래의 불산회수탱크는 평편한 바닥부(21)를 가진 탱크몸체(20)내부에 회수조(22)와 중간조(23), 공급조(24)를 설치하되 회수조(22)일측에는 회수라인(25)을 공급조(24)일측에는 공급라인(26)을 각각 연결설치하고, 상기 각 조사이에는 아래쪽 일부가 걸름망의 형태로 된 칸막이 벽부(27)(28)를 설치하고, 이 탱크몸체(20)의 하부 일측에는 침전이물 배출구(29)를 설치하여서 된 구성으로 되어 있다.FIG. 1 is a cross-sectional view showing the construction of a conventional foshan recovery tank which has been installed and used for the above purposes. The conventional foshan recovery tank has a recovery tank 22 inside the tank body 20 having a flat bottom 21. ) And the intermediate tank 23 and the supply tank 24 are installed, but the recovery line 25 is connected to one side of the recovery tank 22, and the supply line 26 is connected to the one side of the supply tank 24, respectively. The lower part is provided with partition walls 27 and 28 in the form of a strainer, and the lower one side of the tank body 20 is provided with a sediment debris discharge port 29.

이러한 구성에 따라 상기 종래의 불산회수탱크는 회수라인(25)을 통해 회수조(22)로 유입된 사용 불산이 걸름망형태로 된 벽부(27)(28)의 아래쪽을 통과하여 중간조(23), 공급조(24)로 유입되면서 그에 포함되어 있던 이물들이 탱크몸체(20)내의 바닥부(21)쪽으로 침전되어 쌓이고, 이물들이 침전제거된 깨끗한 불산은 공급조(24)상부의 공급라인(26)을 통해 사용처로 다시 공급되며, 탱크바닥부에 쌓인 침전이물(15)들은 주기적으로 혹은 필요한 임의의 시기에 밸브(30)를 열고 펌프(31)를 가동시켜 배출구(29)를 통해 배출제거하게 되는바, 이는 이물들이 침전되어 쌓이는 탱크 바닥부(21)가 전체적으로 편평하게 되어 있어 침전이물들이 어느 한 곳으 이는 이물들이 침전되어 쌓이는 탱크 바닥부(21)가 전체적으로 편평하게 되어 있어 침전이물들이 어느 한 곳으로 집중되지 못하고 바닥부(21)전체로 퍼져 있게 되기 때문에 배출구(29)를 통한 침전이물들의 배출제거시 침전이물 전량이 깨끗이 배출되기 어렵고 배출구(29)로부터 면쪽의 침전이물들이 많이 남아 있게 되어 이를 작업자가 직접 퍼내어 제거시켜 주어야 하는 불편이 있으며, 또한 부주의로 인해 정도이상 과량의 침전이물들이 탱크내부에 쌍여 있는데도 이를 적시에 배출제거치 못한 경우(실제 이러한 경우가 빈번히 발생한다.)는 공급조(24)로 부터 사용처로 재 공급되어지는 불산에 침전이물들주의 일부가 다시 섞여 공급되어짐으로써 판넬의 세척불량을 야기하게 되는 문제점이 있었다.According to this configuration, the conventional hydrofluoric acid recovery tank passes through the lower portion of the wall portions 27 and 28 in the form of a strain net, which is introduced into the recovery tank 22 through the recovery line 25. , The foreign matter contained in the supply tank 24 is precipitated and accumulated toward the bottom portion 21 of the tank body 20, and the clean hydrofluoric acid from which the foreign matters are removed is supplied to the supply line 26 on the supply tank 24. The sedimentary debris (15) accumulated in the bottom of the tank is periodically removed or discharged through the outlet (29) by opening the valve (30) and operating the pump 31 at any time necessary This is because the tank bottom portion 21 where the foreign matters are accumulated and is flattened as a whole, so that the sedimentary foreign matters is the tank bottom part 21 where the foreign matters are deposited and accumulated as a whole. Home to this one place Since it is not possible to spread throughout the bottom portion 21, the entire amount of sediment is difficult to be discharged cleanly when the discharge of sediment debris through the outlet 29 is removed, and a lot of sediment debris on the surface side from the outlet 29 remains. It is inconvenient for the worker to scoop it out and remove it. In addition, if the sediment of excess excess amount is accumulated in the tank due to carelessness, it cannot be discharged in a timely manner (actually this happens frequently). There was a problem in that the sedimentation in the hydrofluoric acid which is supplied back to the place of use from the supply tank 24 is mixed again and supplied to cause a poor cleaning of the panel.

본 고안은 이러한 종래의 문제점을 해소하기 위해 안출한 것으로, 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is devised to solve such a conventional problem, it will be described in detail based on the accompanying drawings as follows.

본 고안은 제2도에 도시된 바와 같이 내부에 회수라인(5)이 연결설치된 회수조(2), 중간조(3), 공급라인(6)이 연결설치된 공급조(4)를 설치하고 이들 각 조사이에는 아래쪽 일부가 걸름망형태로 된 칸막이 벽부(7)(8)를 설치한 탱크몸체(1)를 포함하는 불산회수탱크를 구성함에 있어서, 탱크몸체(1)의 하부에 아래쪽이 좁고 위쪽이 넓은 누두상의 바닥부(9)를 형성하고, 이 바닥부(9)의 아래쪽 좁은 구경부위에 침전이물 배출구(10)를 형성하여 이에 솔레노이드밸브(11) 및 펌프(12)가 설치된 배출라인(13)을 연결설치하며, 탱크몸체(1)의 내부적소에는 이 탱크몸체(1)내부의 바닥부(9)상에 침전이물(15)들이 설정높이까지 쌓였을 때 상기 밸브(11) 및 펌프(12)를 일정시간 작동시켜 침전이물(15)들을 배출제거토록 할 수 있는 센서(또는 리미트스위치) 수단(14)을 설치하여서 된 것이다.The present invention is installed in the recovery tank (2), the intermediate tank (3), the supply line (6) connected to the supply line 6 is installed therein the recovery line 5 is installed therein as shown in FIG. Each irradiator includes a foshan recovery tank including a tank body (1) provided with partition walls (7) (8) in which a lower portion is formed in a strain net, wherein the bottom of the tank body (1) is narrow and has a lower bottom. This wide nipple-like bottom portion 9 is formed, and the sediment foreign substance outlet 10 is formed in the narrow aperture portion of the bottom portion 9 so that the solenoid valve 11 and the pump line 12 are provided with a discharge line. (13) is connected and installed in the internal position of the tank body (1) when the sedimentary debris (15) on the bottom portion (9) inside the tank body (1) to the set height when the valve (11) and By installing a sensor (or limit switch) means 14 which allows the pump 12 to operate for a certain time so that the sediment debris 15 can be discharged. It is.

상기 센서수단(14)과 밸브(11), 펌프(12)등의 적합한 작동을 위해 이들은 마이크프로세서와 같은 제어수단(16)에 전기적으로 연결설치될 수 있다.For proper operation of the sensor means 14, the valve 11, the pump 12, etc., they may be electrically connected to a control means 16 such as a microphone processor.

이와 같이 구성된 본 고안의 불산회수탱크는 전술한 바와 같은 사용불산의 회수 및 재공급사용 고정에서 사용불산으로부터의 침전이물(15)들이 탱크내부에 설정높이까지 쌓이게 되면 센서수단(14)이 작동하여 밸브(11)를 개방작동시킴과 동시에 펌프(12)를 가동시켜 상기 침전이물(15)들을 배출구(10) 및 그에 연결된 배출라인(13)을 통해 정해진 장소로 자동적으로 배출제거할 수 있으므로 탱크내부에 정도이상 과량의 침전이물들이 쌓여 판넬의 세척불량을 초래하게 되는 일을 완전 방지할 수 있으며, 또한 침전이물(15)들이 쌓이는 탱크몸체(1)의 바닥부(9)가 상기 침전이물(15)들을 배출구(10)쪽으로 자연스럽게 잘 모아줄 수 있는 경사진 형태로 되어 있기 때문에 배출구(10)로부터 먼쪽의 침전이물들까지 항시 깨끗이 배출제거할 수 있고, 이로써 종래와 같이 펌프 작동을 통한 침전이물배출작업후에도 탱크내 잔존 침전이물들을 작업자가 직접 퍼내어 제거해야 했던 불편을 완전히 해소할 수 있게된 유용한 효과를 지닌 것이다.The hydrofluoric acid recovery tank of the present invention configured as described above operates the sensor means 14 when the sediment foreign matters 15 from the hydrofluoric acid are accumulated to the set height in the tank in the recovery and resupply of the used hydrofluoric acid as described above. By opening the valve 11 and operating the pump 12 at the same time, the sedimentary debris 15 can be automatically discharged to a predetermined place through the outlet 10 and the discharge line 13 connected thereto. Excessive amount of sediment foreign matter accumulated in the tank can be completely prevented from causing a poor washing of the panel, and also the bottom 9 of the tank body (1) where the sediment foreign matter (15) is stacked Since it is in an inclined form that can naturally collect the sediment foreign materials 15 toward the outlet 10, the sediment foreign matters far away from the outlet 10 can be always cleanly discharged and removed. Sediment through the pump operation After the discharge operation has a useful effect that can completely eliminate the inconvenience that the operator had to manually remove the residual sediment in the tank.
