Description

슬러지탱크용 튜브 압력 전달식 액면계Tube Pressure Transfer Liquid Level Meter for Sludge Tank

본 고안은 슬러지탱크의 내부에 투입되는 액상물의 액면을 표시하기 위한 슬러지탱크의 액면계에 관한 것으로, 특히 슬러지탱크의 내부에 슬러지가 다량 함유된 액상물이나 점도가 높은 액상물이 충진된 경우에도 오차없이 액면을 표시하게 하기 위한 슬러지탱크용 튜브 압력 전달식 액면계에 관한 것이다.The present invention relates to a liquid level gauge of a sludge tank for displaying the liquid level of the liquid introduced into the sludge tank. In particular, an error is obtained even when a liquid containing a large amount of sludge or a high viscosity liquid is filled in the sludge tank. It relates to a tube pressure transfer liquid level meter for a sludge tank for marking the liquid level without water.

일반적으로, 슬러지탱크(S)에는 제1도에 도시된 바와 같이, 측면에 상하방향을 따라 일정크기의 관로가 형성된 중공형태의 액면계가 설치되어 있는데, 이러한 액면계의 관로에 충진된 지시액의 높이를 관찰하므로써, 슬러지탱크의 액면을 식별하게 되는 것이다.In general, as shown in Figure 1, the sludge tank (S) is provided with a hollow liquid level gauge having a constant size pipe in the vertical direction on the side, the height of the indicator liquid filled in the pipe of the liquid level gauge By observing, the liquid level of the sludge tank is identified.

또한, 액면계는 슬러지탱크의 수용공간과 연통된 상태로 설치되어, 이 슬러지탱크에 수용되는 액체상태의 액상물이 액면계의 관로를 따라 승하강되게 되고, 이 승하강되는 액상물의 액면높이를 관찰하면서 충진된 액상물량을 확인하게 되는 것이다.In addition, the liquid level gauge is installed in communication with the receiving space of the sludge tank, the liquid state of the liquid state accommodated in the sludge tank is raised and lowered along the pipeline of the liquid level gauge, while observing the liquid level of the liquid level is lowered The amount of liquid filled will be checked.

즉, 슬러지탱크(S)의 내부에 담겨지는 액상물이 모세관현상에 의해 액면계를 따라 승하강하면서 수위가 변동되는 과정을 통해 탱크내부의 액상물의 고도를 식별하게 되는 것이다.In other words, the liquid level contained in the sludge tank (S) is to identify the altitude of the liquid in the tank through the process of changing the water level while moving up and down along the liquid level meter by the capillary phenomenon.

그런데, 슬러지탱크(S)의 주입구에는 복합혼합물 예컨대, 슬러지가 함유된 액상물이나 또는 점도가 높은 액상물 등이 투입되며, 이러한 이물질들이 함유된 액상물이 액면계의 관로를 따라 승하강하면서 잔류되는 경우 관로를 오염시키게 될 뿐만 아니라 심하게는 액면계의 내부공간에 고착되면서 관로를 폐쇄시키게 되는 문제점이 있었다.However, a composite mixture, such as a sludge-containing liquid or a high-viscosity liquid, is injected into the inlet of the sludge tank S, and the liquid containing these foreign substances is left while being lowered along the pipeline of the liquid level gauge. In case of contaminating the pipeline as well as badly stuck to the internal space of the liquid level, there was a problem of closing the pipeline.

또한, 슬러지탱크(S)의 액면계를 따라 승하강하는 이물질들이 액상물의 이동경로를 방해하는 요소로 작용되므로, 액면계의 지시가 상대적으로 늦어지게 될 뿐만 아니라 정확한 액면지시를 인지시키지 못하게 되는 문제점이 있었다.In addition, since foreign matters descending along the liquid level gauge of the sludge tank S act as an obstacle to the moving path of the liquid, the indication of the liquid level becomes relatively late and there is a problem in that the accurate liquid level indication is not recognized. .

그리고, 슬러지탱크(S)의 액면계를 따라 수위가 변동되는 액상물이 동절기에 관로상에서 동결되는 경우 또는 외부로부터의 이물질이 유입되는 경우에 액면계가 제기능을 수행할 수 없게 되는 문제점이 있었다.In addition, there is a problem in that the liquid level meter is unable to perform a function when the liquid level whose water level is changed along the level gauge of the sludge tank (S) is frozen on the pipeline in winter or when foreign substances are introduced from the outside.

이에, 본 고안은 상기한 바와 같은 제문제점을 해결하기 위하여 안출된 것으로, 액상물에 의해 압축되는 충진물튜브를 슬러지탱크의 내부에 설치하여, 이물질이 함유된 액상물이나 점도가 높은 액상물이 충진된 경우에도 오차없이 액면의 고도를 표시하게 될 뿐만 아니라 액상물과 지시액을 별도로 구성한 상태에서 부동액을 첨가하여 동결되는 것을 방지시킬 수 있도록 된 슬러지탱크용 튜브압력 전달식 액면계를 제공하는 데에 그 목적이 있다.Thus, the present invention was devised to solve the problems as described above, by installing a filling tube that is compressed by the liquid inside the sludge tank, the liquid containing a foreign substance or a liquid having a high viscosity is filled In order to provide a tube pressure transfer liquid level gauge for sludge tank which can not only display the altitude of the liquid level without errors but also prevent the freezing by adding the antifreeze liquid with the liquid and indicator liquid separately configured. There is this.

As shown in these figures, while the inlet is formed on the upper surface of the sludge tank (S) for injecting the liquid containing sludge, the pump pipe inlet (S ') and the inlet for discharging the liquid on both sides In the tube pressure transmission liquid level gauge for the sludge tank having a structure in which the transparent tube (4) is installed at the same height to visually identify the amount of liquid introduced into the liquid, the upper end of the transparent tube (4) is for preventing the infiltration of foreign matter from the outside. The vent filter 8 is installed, and the bottom end of the transparent tube 4 is filled with an indicator liquid containing an antifreeze solution to prevent freezing while being inserted through the inside of the sludge tank S. While the inner pipe (2) is installed in communication, on the outer circumferential surface of the binding pipe (2) is equipped with a flexible material tube (1) of varying shrinkage depending on the specific gravity of the liquid introduced into the inlet of the sludge tank (S) It is structured.

슬러지탱크(S)의 일측에는 투명튜브(4)와의 결속을 위한 노즐(4')이 설치되며, 노즐(4')의 하단부에는 펌프배관입구와 동일높이에 가스켓(3')과 플랜지(3)가 구비된 결속파이프(2)가 보울팅결합된 구조로 되어 있다.One side of the sludge tank S is provided with a nozzle 4 'for binding with the transparent tube 4, and the lower end of the nozzle 4' has a gasket 3 'and a flange 3 at the same height as the pump pipe inlet. ), The binding pipe 2 is provided with a bowling coupling structure.

결속파이프(2)의 외주면에는 다수개의 압력전달구멍(2')이 통공되면서 이 압력전달구멍(2')의 외부에는 지시액이 충진된 충진물튜브(1)를 씌원 양측을 결속파이프(2)에 밀폐시킨 구조로 되어 있다.The outer circumferential surface of the binding pipe 2 is provided with a plurality of pressure transfer holes 2 ', and both sides of the pressure transfer hole 2' are filled with the filling tube 1 filled with the indicator liquid on the outside of the pressure transfer hole 2 '. It is a structure sealed to the.

또한, 결속파이프(2)의 상단부 노즐(4')에는 증류수와 동결방지용 부동액이 일정비율로 채워지도록 된 투명튜브(4)가 연결설치되고, 이 투명튜브(4)의 상단부에는 지지대(7)로 지지한 상태에서 연결파이프(6)가 연결설치되며, 이 연결파이프(6)의 단부에는 외부공기를 정화시키기 위한 벤트필터(8)가 설치되는 한편, 상기 투명튜브(4)의 내측벽에는 작업자가 육안으로 확인할 수 있도록 일정한 간격을 갖는 눈금이 새겨진 액면표지판(5)이 설치된 구조로 되어 있다.In addition, the upper end nozzle 4 'of the binding pipe 2 is connected with a transparent tube 4 which is filled with distilled water and an antifreeze antifreeze at a constant ratio, and a support 7 is provided at the upper end of the transparent tube 4.

It is a structure in which a liquid level plate (5) engraved with a graduation with a predetermined interval so that the operator can check with the naked eye.

물론, 벤트필터(8)의 내부에는 스펀지 등의 여과물이 충진된 구조로 되어 있다.Of course, the inside of the vent filter 8 has a structure in which a filtrate such as a sponge is filled.

이하, 상기와 같이 구성된 본 고안의 작용을 첨부된 예시도면을 상세하게 설명하면 다음과 같다.Hereinafter, described in detail the accompanying drawings illustrating the operation of the present invention configured as described above are as follows.

먼저, 슬러지탱크(S)의 주입구를 통해 유입되는 액상물과 충진물튜브(1)에 충진된 지시액이 서로 분리된 상태이므로, 충진물튜브(1)에 가해지는 액상물의 압력에 의해 내부의 액면지시액이 투명튜브(4)로 상승 또는 하강되면서 액면이 표시된다.First, since the liquid flowing through the inlet of the sludge tank S and the indicator liquid filled in the filler tube 1 are separated from each other, the liquid level is indicated by the pressure of the liquid applied to the filler tube 1. The liquid level is displayed as the liquid rises or falls into the transparent tube 4.

그리고, 투명튜브(4)를 따라 승하강되는 지시액의 높이는 액면표지판(5)으로 표시되는데, 이 액면표지판(5)의 눈금은 투명튜브(40)의 중심부와 액상물의 높이에 슬러지의 비중과 투명튜브(4)에 충진된 지시액 비중을 나눈 값을 곱한 값으로 표시된다. 즉, 슬러지탱크(S)와 투명튜브(4)가 양쪽 모두가 대기압상태에 있으므로, 충진물튜브(1)의 표면을 가해지는 압력이 액면표지판(5)으로 직접 표시되는 것이다.In addition, the height of the indicator liquid which is raised and lowered along the transparent tube 4 is represented by the liquid level plate 5, and the scale of the liquid level plate 5 is determined by the specific gravity of the sludge at the center of the transparent tube 40 and the height of the liquid. It is expressed as the value multiplied by the value divided by the specific gravity of the indicator liquid filled in the transparent tube (4). That is, since both the sludge tank S and the transparent tube 4 are at atmospheric pressure, the pressure applied to the surface of the fill tube 1 is directly displayed by the liquid level label 5.

물론, 충진물튜브(1)를 설치하는 경우에는 충진물튜브의 복원력이 미약하므로 실제 슬러지를 채우면서 액면표지판(5)에 액면을 표시해야 정확하게 액면표시가 되며, 이때 충진물튜브(1)에 충진된 지시액의 비중이 슬러지탱크(S)의 슬러지 비중보다 상대적으로 낮으므로 액면표지판(5)은 슬러지탱크(S)의 최대수면에다 지시액의 비중과 슬러지의 비중차를 환산한 값을 더한 높이로 설치해야만 한다.Of course, when the filling tube (1) is installed, the restoring force of the filling tube is weak, so the liquid level must be displayed on the liquid level plate (5) while filling the actual sludge, and the liquid level is accurately displayed. Since the specific gravity of the liquid is relatively lower than that of the sludge tank (S), the liquid level indicator (5) is installed at the height of the maximum water level of the sludge tank (S) plus the value obtained by converting the specific gravity of the indicator liquid and the specific gravity difference of the sludge. must do it.

이상에서 설명한 바와 같이 본 고안에 따른 슬러지탱크용 튜브압력 전달식 액면계에 의하면, 슬러지탱크(S)의 액상물과 밀폐된 충진물튜브(1)를 설치하게 되므로 액상물과 지시액이 상호 접촉됨이 없게 되어 지시액의 오염이 미연에 방지될 뿐만 아니라 액상물에 이물질이 함유되었거나 점도가 높은 경우에도 광범위하게 사용할 수 있게 되므로 액상물 액면표시의 정확성이 향상되는 효과가 있다.As described above, according to the tube pressure transmission liquid level gauge for the sludge tank according to the present invention, the liquid material and the sealed filling tube 1 are installed in the sludge tank S so that the liquid and the indicator liquid do not come into contact with each other. Therefore, the contamination of the indicator liquid is prevented in advance, and since the foreign matter is contained in the liquid or the viscosity is high, it can be widely used, thereby improving the accuracy of the liquid level display.

또한, 충진물튜브(1)에 부동액이 함유된 지시액을 충진하게 되므로 동절기에도 액면표시가 가능하게 될 뿐만 아니라 벤트필터(8)에 의해 이물질이 걸러지게 되므로 충진물튜브에 충진된 지시액의 수명이 연장되는 효과가 있다.In addition, since the indicator tube containing the antifreeze solution is filled in the filler tube 1, the liquid level display is not only possible in winter, but also the foreign matter is filtered out by the vent filter 8 so that the life of the indicator liquid filled in the filler tube is extended. It has a prolonged effect.
