본 고안은 전해법으로 강중 비금속 개재물을 추출하기위한 전해조에 관한 것으로, 보다 상세히는 전해조내부에 높이가 다른 2개의 저항판을 각각 설치하여 전해액이 오버플로우(overflow)에 의해 급,배액이 이루어지고, 전해조내에서 전해액의 균일한 유동 및 농도가 유지되며, 전해조내의 전해액 수위를 항상 일정하게 유지할 수 있고, 카트리지식 여과기의 설치로 전해액의 청정도를 유지하면서, 다량의 시료를 동시에 처리할 수 있는 전해 추출용 전해조에 관한 것이다.The present invention relates to an electrolytic cell for extracting non-metallic inclusions in steel by the electrolytic method, and more specifically, two resistive plates having different heights are installed in the electrolytic cell, so that the electrolyte solution is overflowed and drained by overflow. The electrolyte can maintain a uniform flow and concentration of the electrolyte in the electrolytic cell, maintain a constant level of the electrolytic solution in the electrolytic cell, and install a cartridge filter to maintain the cleanliness of the electrolytic solution while maintaining the cleanness of the electrolytic solution. It relates to an electrolytic cell for extraction.
제1도에 나타낸 바와같이, 실용신안 등록출원 제89-20629호에 발표 공보된 일반적인 전해 추출용 전해조의 기술구성은 다음과 같다.As shown in FIG. 1, the technical configuration of a general electrolytic extraction electrolyzer disclosed in Utility Model Registration Application No. 89-20629 is as follows.
즉, 다수개의 시료를 동시에 전해할 수 있는 장방형의 전해조(20)에는 시료양극을 잔사물 포집용 면포(5)에 넣어 양극걸이를 이용하여 양극 부스바(2)에 고정하고, 음극판(3)은 음극걸이를 이용하여 음극부스바(1)에 각각 고정한다.That is, in the rectangular electrolytic cell 20 capable of simultaneously delivering a plurality of samples, the sample anode is placed in the surface collecting cloth 5 for the residue, and fixed to the positive electrode busbar 2 using the positive electrode hook, and the negative electrode plate 3. The silver cathode hanger is fixed to the cathode booth bar 1, respectively.
한편, 상기 전해조(20) 외부일측에는 폐하(pH)제어부(8)를 가진 염산 저장기(9)를 갖추며, 전해조(20)내의 수소이온농도를 탐침하기위한 폐하 프루브(probe)(10)와 염산 공급호스(11)를 상기 폐하제어부(8)의 일측에 연결하여 갖추고, 상기 전해조(20)내의 전해액을 순환시키기위한 순환호스(12)와 상기 순환호스(12)의 중간에 순한펌프(7)를 갖추며, 상기 순환호스(12)의 배액부의 일측에는 전해 잔사물을 여과하기 위한 내산용 여과포(6)를 갖춘다.On the other hand, the external side of the electrolyzer 20 is equipped with a hydrochloric acid reservoir 9 having a majesty (pH) control unit 8, and a maize probe 10 for probing the concentration of hydrogen ions in the electrolyzer 20. A hydrochloric acid supply hose 11 is connected to one side of the waste control unit 8 and a pump 7 is disposed between the circulation hose 12 and the circulation hose 12 for circulating the electrolyte in the electrolytic cell 20. ), And one side of the drainage portion of the circulation hose 12 is provided with an acid-proof filter cloth (6) for filtering the electrolytic residue.
그러나, 상기와 같은 기술구성은 종래의 전해 추출용 전해조에서는 다음과 같은 기술적 문제점이 발생된다.However, the technical configuration as described above causes the following technical problems in the conventional electrolytic extraction electrolytic cell.
즉, 전해조(20)내 전해액의 교반효과를 순환펌프(7)에 의한 순환에만 의존하므로서, 상기 전해조(20)내의 전해액 농도가 불균일하게 되고, 시료양극(4)의 위치에 따라 용해속도의 차이가 발생하며, 비금속 개재물 추출을 위한 전해는 시편의 크기에 따라 다르지만, 20∼200시간이상 장기간 전해를 하는 경우, 전해액내 수분의 증발이 발생하여 전해액면이 저하되는 문제가 발생됨으로서, 시편을 원하는 부분까지 전해시킬수가 없었다.That is, since the stirring effect of the electrolyte in the electrolytic cell 20 depends only on the circulation by the circulation pump 7, the concentration of the electrolyte in the electrolytic cell 20 becomes nonuniform, and the difference in the dissolution rate depending on the position of the sample anode 4. And electrolysis for extraction of non-metallic inclusions varies depending on the size of the specimen, but when prolonged electrolysis for 20 to 200 hours or longer, evaporation of moisture in the electrolyte occurs, resulting in a problem of lowering the surface of the electrolyte. Could not be delivered to the part.
또한, 상기 전해조(20)의 작용은 양극 잔사물을 추출하는 것이기 때문에, 다량의 전해잔사물이 발생될 경우, 미세한 잔사물의 일부가 양극시편을 감싸고 있는 잔사물 포집용 포(5)를 빠져나와서 전해액을 오염시키고 있어, 이를 방지하기 위해 내산용 여과포(6)를 이용하여 여과처리를 하고 있지만, 상기 여과포(6)의 장기간 사용으로 막힘이 발생할경우, 이를 교체해주어야 하는데 상기 여과포가 전해조(20)내부에 침전되어 있어 교체작업이 매우 번거러운 문제점이 있다.In addition, since the action of the electrolytic cell 20 is to extract the anode residue, when a large amount of electrolytic residue is generated, a part of the fine residue is taken out of the residue collecting cloth 5 surrounding the anode specimen. It is contaminated with the electrolyte solution, and to prevent this, it is filtered by using the acid-resistant filter cloth (6), but if clogging occurs due to long-term use of the filter cloth (6), it must be replaced, the filter cloth is electrolytic cell (20 There is a problem that replacement work is very cumbersome because it is precipitated inside.
따라서, 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 그 목적은 전해액의 낙하를 이용하여 교반시키고, 전해조 내부의 전해액 농도를 균일하게 할수 있으며, 균일한 배액과 균일한 전해액 수면을 유지하여 전해초기와 말기 모두 원하는 균일한 양극시편의 전해 및 용해효과를 얻을 수 있고, 카트리지식 여과기에 의해 전해액을 정화시킬수 있어 전해조 내부의 청소주기가 길어지고, 교체작업도 간편한 전해추출용 전해조를 제공함에 있다.Therefore, the present invention has been devised to solve the above problems, the purpose is to stir by using the drop of the electrolyte, to make the concentration of the electrolyte solution inside the electrolytic cell uniform, and to maintain a uniform drainage and uniform electrolyte surface The electrolytic and dissolving effect of the desired uniform anode specimen can be obtained at the beginning and the end of the electrolysis, and the electrolyte can be purified by the cartridge type filter, so the cleaning cycle inside the electrolyzer is lengthened, and the electrolytic extraction for electrolysis extraction is easy.

제2도에 나타낸 바와같이, 강중 개재물을 추출하기위한 전해추출용 전해조(100)에서, 장방형의 전해조(20)는 극간거리에 따라 10~15개의 시편을 동시에 전해할수 있는 크기로 제작하며, 상기 전해조(20)는 공급된 전해액의 기능에 따라, 급액부(20a), 전해추출부(20b), 배액부(20c)등의 3부분으로 구분할수 있다.As shown in Figure 2, in the electrolytic extraction electrolytic cell 100 for extracting the inclusions in the steel, the rectangular electrolytic cell 20 is produced in a size capable of simultaneously delivering 10 to 15 specimens according to the distance between the poles, The electrolytic cell 20 can be divided into three parts, such as a liquid supply part 20a, an electrolytic extraction part 20b, and a drainage part 20c, depending on the function of the supplied electrolyte solution.
그리고, 제3도에 나타낸 바와같이, 상기 전해조(20)의 외부일측에는 폐하제어부(8)를 갖춘 염산 저장기(9)가 위치하고, 상기 염산 저장기(9)의 일측에 연결된 공급호스(11)와 폐하프루브(10)가 상기 급액부(20a)내부에 연결되고, 상기 전해조(20)의 측면높이와 수직 평행하며, 일정높이를 가지는 급액부 저항판(31)이 전해조(20)내에 장착되어 급액부(20a)를 구성한다.And, as shown in Figure 3, the hydrochloric acid reservoir (9) with a load control unit 8 is located on the outer side of the electrolytic cell 20, the supply hose 11 connected to one side of the hydrochloric acid reservoir (9) ) And the closed bottom probe 10 are connected to the inside of the liquid supply part 20a, and the liquid supply part resistance plate 31 having a predetermined height parallel to the side height of the electrolytic cell 20 is mounted in the electrolytic cell 20. To form the liquid supply part 20a.
한편, 전해추출부(20b)에는 시료양극(4)을 잔사물 포집용 면포(5)에 넣어 양극걸이를 이용하여 양극 부스바(2)에 고정하고, 음극판(3)은 음극걸이를 이용하여 음극부스부(1)에 고정하며, 전해조(20)내에 공급된 전해액을 순환시키기위한 순환호스(12)와 상기 순환호스(12)의 중간에 순환펌프(7)와 전해 잔사물을 여과하기 위한 카트리지식 여과기(41)를 상기 전해조(20)의 외부에 갖춘다.Meanwhile, the sample anode 4 is placed in the electrolytic extracting unit 20b in the surface cloth 5 for collecting the residue, and fixed to the anode busbar 2 using the anode hanger, and the cathode plate 3 uses the cathode hanger. It is fixed to the negative electrode booth portion (1), the circulation hose 12 for circulating the electrolyte solution supplied in the electrolytic cell 20 and for filtering the circulation pump 7 and the electrolytic residue in the middle of the circulation hose 12 A cartridge type filter 41 is provided outside the electrolytic cell 20.
또한, 전해 및 용해작용을 마친 전해액이 모아지는 배액부(20c)에는, 상기 급액부 저항판(31)의 높이보다 작고, 전해조(20)의 측면높이와 수직 평행한 배액부 저항판(51)을 설치하며, 상기 배액부(20c) 일측에는 순환호스(12)가 연결된다.In addition, in the drainage portion 20c in which the electrolyte solution that has completed the electrolytic and dissolving actions is collected, the drainage portion resistance plate 51 smaller than the height of the liquid supply portion resistance plate 31 and perpendicular to the side height of the electrolytic cell 20 is provided. It is installed, the circulation hose 12 is connected to one side of the drainage portion (20c).
이하, 본 고안에 따른 전해추출용 전해조의 작용 및 효과에 대해서 상세히 설명한다.Hereinafter, the operation and effects of the electrolytic extraction electrolytic cell according to the present invention will be described in detail.
즉, 10% 염화 제1철과, 1% 구연산나트륨을 포함하는 전해액은 폐하제어부(8)에 의해서 농도가 일정수준으로 유지되며, 공급호스(11) 및 순환호스(12)를 통해 급액부(20a)에 공급되고,수직한 급액부 저항판(31)에 의해 오버플로우(overflow)를 이루면서, 전해추출부(20b)로 급액이 되며, 상기 오버플로우에 의해 낙하가 발생하여 전해액을 교반하고, 전해조(20)의 폭방향으로 균일한 급액이 이루어진다.That is, the electrolyte solution containing 10% ferrous chloride and 1% sodium citrate is maintained at a constant level by the majesty control unit 8, and the liquid supply unit through the supply hose 11 and the circulation hose 12 ( 20a), the liquid is supplied to the electrolytic extraction unit 20b while overflowing by the vertical liquid supply part resistance plate 31, and a drop occurs due to the overflow, and the electrolyte is stirred. Uniform liquid supply is made in the width direction of the electrolytic cell 20.
한편, 상기 낙하 작용에 의해 균일한 전해액이 전해 추출부(20b)에서 내부유동이 일어나고, 전해액 상층부로 불순물이 부유하게 되며, 이어서, 상기 불순물은 전해액의 흐름을 타고, 배액부(20c)로 이송하여 제거되며, 전해중의 전해액 수위면은 배액부(20c)의 저항판(51)에 의하여 항상 일정하게 유지될 수 있으며, 수분증발에 따른 전해액 보충시기는 배액부(20c)의 수위변화를 관찰하여 쉽게 판단 보충할 수 있다.On the other hand, a uniform electrolyte is caused to flow inside the electrolytic extraction unit 20b by the drop action, and impurities are suspended in the upper part of the electrolyte, and the impurities are then transferred to the drainage unit 20c by the flow of the electrolyte. It is removed by, the electrolyte level surface during the electrolysis can be always maintained by the resistance plate 51 of the drainage portion 20c, the electrolyte replenishment time due to evaporation of water observed the change in the water level of the drainage portion 20c You can easily replenish your judgment.
그리고, 상기 배액부(20c)의 전해액은 순환호스(12)를 통해 급액부(20a)로 순환되며, 상기 순환 및 적정전해량, 즉 오버 플로우가 발생할 정도의 전해액 공급은 제3도에 도시된 순환펌프(7)에 의해 이루어지며, 정전압 직류전원장치(미도시)와 양극, 음극부스바(1),(2)를 각각 연결하여 통전시키면 전해가 시작되고, 일정시간이 경과한 카트리지식 여과기(51)는 필터만을 교환하여 전해액의 청정도를 유지한다.In addition, the electrolyte of the drainage portion 20c is circulated to the feed portion 20a through the circulation hose 12, and the circulation and proper electrolyte amount, that is, the supply of electrolyte to the extent that overflow occurs is shown in FIG. It is made by the circulation pump (7), the constant voltage DC power supply (not shown) and the positive and negative booth bar (1), when the electricity is connected to each of the (2), the electrolysis starts, a certain time has passed cartridge type filter 51 replaces only the filter to maintain the cleanliness of the electrolyte solution.
이하, 본 고안의 효과를 실험예에 의해서 보다 구체적으로 설명한다.Hereinafter, the effect of the present invention will be described in more detail by the experimental example.
표 1은 본 고안에 따른 전해추출용 전해조와 종래의 전해조에서 연주주편을 각각 8개식 90시간동안 전해후 용해량 및 용해율을 비교한 결과이다.Table 1 shows the results of comparing the dissolution and dissolution rates of the electrolytic extraction electrolytic cell according to the present invention and the electrolytic cast steel in the conventional electrolytic cell for eight types of 90 hours each.
[표 1]TABLE 1
표 1을 보아 본 고안에 따른 전해추출용 전해조에서 전해한 경우, 평균 418kg이 용해되어 전해전 무게대비 평균 65%의 용해율을 보인 반면, 종래의 전해조에서 전해한 경우에는 평균 370kg이 용해되어 약 58%의 용해율을 보임에 따라, 본 고안에 따른 전해추출용 전해조의 용해율이 약 7% 향상된 것을 알수 있다.As shown in Table 1, when electrolyzed in the electrolytic extraction electrolytic cell according to the present invention, the average 418kg was dissolved to show an average dissolution rate of 65% relative to the weight before electrolytic, whereas when electrolyzed in the conventional electrolyzer, the average of 370kg was dissolved to about 58 By showing the dissolution rate of%, it can be seen that the dissolution rate of the electrolytic cell for electrolytic extraction according to the present invention is improved by about 7%.
상기와 같은 결과차이는 본 고안에 따른 전해추출용 전해조에서는 항상 전해액수위가 일정하여 균일하게 전해된 반면, 종래의 전해조에서는 시간경과함에 따라 전해액 수위가 감소하여 시편상부의 용해가 불균일하게 일어나기 때문인 것이다.The result difference is that the electrolyte level for the electrolytic extraction electrolytic cell according to the present invention is always constant and uniformly delivered, whereas in the conventional electrolytic cell, the electrolyte level decreases with time, resulting in uneven dissolution of the specimen. .
따라서 본 고안에 따른 전해추출용 전해조에 의하면, 전해조 내부의 급액부 저항판에 의하여 낙하가 발생하고, 상기 낙하에 의해 전해액의 교반효과 및 균일한 급액이 이루어져서, 전해액 농도 및 유동의 균일화가 얻어지며, 전해액 상부로 불순물이 부유되어 그 제거가 용이하게 되는 것이다.Therefore, according to the electrolytic extraction electrolytic cell according to the present invention, the drop is generated by the liquid supply part resistance plate inside the electrolytic cell, the stirring effect and uniform supply of the electrolyte is achieved by the drop, the electrolyte concentration and the flow uniformity is obtained. The impurities are suspended in the upper part of the electrolyte, and the removal thereof is easy.
그리고, 배액부 저항판에 의해 전해추출부의 수위가 일정하게 유지하여 다량의 시료를 동시에 전해할 경우, 전해초기와 말기 모두 균일한 전해 및 높은 용해율을 얻을 수 있으며, 카트리지식 여과기를 장착함으로서 전해조내부의 청소주기가 길어지고, 필터교환 조작이 간단하게 되는 실질적인 효과가 발생한다.In addition, when the level of the electrolytic extraction unit is kept constant by the drainage resistance plate to deliver a large amount of samples simultaneously, uniform electrolysis and high dissolution rate can be obtained at the beginning and the end of the electrolytic cell. The practical effect is to lengthen the cleaning cycle and to simplify the filter replacement operation.
