본 발명은 스테인레스 냉연공장의 탈지설비에서 탈지대상인 스트립의 표면에 잔류된 압연유, 지분, 철분 등의 이물질을 효과있게 제거할 수 있도록 개선된 스트립 탈지용액의 순환장치에 관한 것이다.The present invention relates to an apparatus for circulating strip stripping solution improved to effectively remove foreign substances such as rolling oil, stake, and iron remaining on the surface of strip to be stripped in a stainless steel cold rolling plant.

통상, 스테인레스 냉연공장의 광휘소둔라인에서 냉간압연한 스트립은 소둔하기 전에 탈지설비를 거쳐 스트립의 표면에 잔류된 압연유, 지분, 철분 등의 이물을 제거하게 된다.In general, the cold-rolled strip in the bright annealing line of the stainless cold rolling mill removes foreign substances such as rolling oil, stake, iron, etc. remaining on the surface of the strip through a degreasing facility before annealing.

탈지설비는 도 1의 도시와 같이 구성되어 진행되는 스트립(1)의 표면에 탈지탱크(10)의 탈지용액(12)을 스프레이하여 스트립(1) 표면에 잔류된 이물질을 제거하게 된다.The degreasing apparatus sprays the degreasing solution 12 of the degreasing tank 10 on the surface of the strip 1 that is configured and progressed as shown in FIG. 1 to remove foreign substances remaining on the surface of the strip 1.

탈지탱크(10)에는 열교환기(14)가 내장되어 있어 탈지용액(12)을 적정온도로 가열시키게 되고 탈지탱크(10)의 일측에 부착된 온도센서(16)에 의해 관리온도, 이를테면 대략 75℃(이 온도일때 세척이 가장 잘됨)로 유지되게 되면 펌프(18)를 가동시켜 알카리공급라인(20)을 통해 탈지용액(12)을 탈지구간인 프리크리닝탱크(22), 브러쉬탱크(24), 크리닝탱크(26)로 공급함과 동시에 다수의 스프레이노즐(28)을 통해 탈지용액(12)을 스트립(1)의 상하면에 분사함으로써 그 표면에 잔류된 이물을 제거하게 된다.The degreasing tank 10 includes a heat exchanger 14 to heat the degreasing solution 12 to an appropriate temperature and is managed by a temperature sensor 16 attached to one side of the degreasing tank 10, such as approximately 75. When it is maintained at ℃ (the best cleaning at this temperature), the pump 18 is operated to remove the degreasing solution 12 through the alkali supply line 20, the pre-cleaning tank 22, the brush tank 24. In addition, while supplying to the cleaning tank 26, the degreasing solution 12 is sprayed on the upper and lower surfaces of the strip 1 through a plurality of spray nozzles 28 to remove foreign substances remaining on the surface.

탈지작업에 사용된 탈지용액은 회수배관(30)을 통해 수집되어 다시 탈지탱크(10)로 회수되어 재활용되는 순환을 반복하게 된다.The degreasing solution used in the degreasing operation is collected through the recovery pipe 30 to be recovered and recycled back to the degreasing tank 10 to repeat the circulation.

그런데, 이와 같은 구조의 탈지설비에서는 특히 탈지용액(12)의 온도관리가 중요한 바, 탈지용액이 관리온도 범위에서 스트립(1)에 분사될 때 최적의 탈지성능 을 발휘할 수 있으나 종래에는 도시와 같이 온도센서(16)가 탈지탱크(10)에 직접 부착되어 있어 탈지탱크(10)에서는 탈지용액(12)을 관리온도 범위(대략 75℃ 내외)로 용이하게 관리할 수 있으나 알카리공급라인(20)을 타고 펌핑되는 과정에서 특히 동절기에는 열손실이 커 실제 스트립(1)에 분사될 때에는 관리온도 범위 보다 현저히 떨어진 온도에서 분사됨으로써 탈지효율이 급격히 저하되는 단점을 유발하게 된다.However, in the degreasing equipment having such a structure, in particular, the temperature management of the degreasing solution 12 is important. When the degreasing solution is sprayed onto the strip 1 in the management temperature range, the degreasing performance can be exhibited optimally. The temperature sensor 16 is directly attached to the degreasing tank 10, so that the degreasing solution 10 can be easily managed in a management temperature range (about 75 ° C or less) in the degreasing tank 10, but the alkali supply line 20 In the process of pumping in, especially during the winter heat loss is large, when sprayed on the actual strip (1) by spraying at a temperature significantly lower than the management temperature range causes a disadvantage that the degreasing efficiency is sharply lowered.

또한, 세개의 펌프(18)중 하나는 휴지시킨 상태에서 나머지 두대의 펌프로 프리크리닝탱크(22), 브러쉬탱크(24) 및 크리닝탱크(26)와 같이 3군데의 탱크로 탈지용액을 펌핑하게 되므로 그 펌핑력이 약하여 탈지용액의 공급이 원활치 못한 단점이 파생된다.In addition, one of the three pumps (18) in the rest state to pump the degreasing solution to three tanks, such as the pre-cleaning tank 22, brush tank 24 and cleaning tank 26 with the other two pumps. As a result, the pumping force is weak, so that the supply of the degreasing solution is not smooth.

뿐만 아니라, 탈지과정에서 스트립(1) 표면 및 브러쉬탱크(24)에서 탈락된 브러쉬칩, 지분과 같은 이물질이 회수되는 탈지용액과 함께 회수되어 재사용됨으로써 펌핑시 필터를 폐쇄하거나 혹은 알카리공급라인(20)을 막아 탈지용액의 공급불량을 초래하는 단점을 유발하게 된다.In addition, by removing and reusing the degreasing solution in which the foreign substances such as the brush chip and the stake removed from the surface of the strip 1 and the brush tank 24 during the degreasing process are recovered and reused, the filter is closed or the alkaline supply line 20 is removed. ), Which leads to a drawback of poor supply of degreasing solution.

본 발명은 상술한 바와 같은 종래 기술이 갖는 제반 문제점을 감안하여 이를 해결하고자 창출한 것으로, 탈지설비의 온도측정 구조를 개선하여 항상 일정한 온도를 갖는 탈지용액을 스트립 표면에 지속적으로 분사토록 함으로써 탈지효율의 향상을 도모함은 물론 회수되는 탈지용액에 함유된 이물을 걸러낸 후 회수토록 하여 필터나 배관의 막힘현상을 방지하고, 브러쉬탱크측으로는 우회공급라인을 설치하여 탈지용액의 원활한 공급을 유도할 수 있도록 한 스트립 탈지용액의 순환장치를 제공함에 그 목적이 있다.The present invention was created in view of the above-described problems of the prior art, and has been created to solve this problem. By improving the temperature measurement structure of the degreasing equipment, the degreasing efficiency is ensured by continuously spraying a degreasing solution having a constant temperature on the strip surface. In addition to improving the efficiency of the degreasing solution, the foreign matter contained in the recovered degreasing solution can be filtered and collected to prevent clogging of the filter or pipe, and a bypass supply line can be installed on the brush tank side to induce smooth supply of the degreasing solution. It is an object of the present invention to provide a circulation device for stripping stripping solution.

본 발명의 상기한 목적은 탈지탱크에 수용된 탈지용액을 프리크리닝탱크와 크리닝탱크로 공급할 수 있도록 연결된 알카리공급라인과; 상기 알카리공급라인상에 설치된 열교환기와; 상기 열교환기의 상측 알카리공급라인상에 설치된 온도센서와; 상기 온도센서의 인접상측 알카리공급라인에서 분기되어 상기 탈지탱크와 연결배설된 리턴라인과; 상기 리턴라인 및 그 분기위치 인접 상측의 알칼리공급라인상에 설치된 공급 및 리턴솔레노이드밸브와; 상기 탈지탱크에 수용된 탈지용액을 브러쉬탱크로 공급할 수 있도록 상기 알카리공급라인과 별개로 설치된 우회라인과; 상기 프리크리닝탱크 및 크리닝탱크의 하단과 상기 탈지탱크를 연결하는 제1회수배관과; 상기 브러쉬탱크와 탈지탱크를 연결하는 제2회수배관과; 상기 제2회수배관상에 설치된 이물제거기를 포함하여 구성되는 것을 특징으로 하는 스트립 탈지용액의 순환장치를 제공함에 의해 달성된다.The above object of the present invention is an alkali supply line connected to supply the degreasing solution contained in the degreasing tank to the pre-cleaning tank and the cleaning tank; A heat exchanger installed on the alkali supply line; A temperature sensor installed on an alkali supply line above the heat exchanger; A return line branched from an alkali supply line adjacent to the temperature sensor and connected to the degreasing tank; A supply and return solenoid valve provided on an alkali supply line above said return line and its branching position; A bypass line installed separately from the alkali supply line to supply the degreasing solution contained in the degreasing tank to the brush tank; A first recovery pipe connecting the lower end of the precleaning tank and the cleaning tank and the degreasing tank; A second recovery pipe connecting the brush tank and the degreasing tank; It is achieved by providing a circulator of the strip degreasing solution, characterized in that it comprises a debris remover installed on the second recovery pipe.

이하에서는, 첨부도면을 참조하여 본 발명을 보다 상세하게 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 순환장치의 개략적인 설치상태를 보인 구성 블럭도이다.Figure 2 is a block diagram showing a schematic installation state of the circulation device according to the present invention.

도 2에 따르면, 본 발명은 탈지용액(12)이 충만된 탈지탱크(10)로부터 스트립(1)이 통판되는 프리크리닝탱크(22) 및 크리닝탱크(26)를 연결하는 알칼리공급배관(20')과, 상기 알카리공급라인(20')과 별도로 상기 탈지탱크(10)와 브러쉬탱크(24)를 연결하는 우회라인(60)을 설치하여 구성된다.According to FIG. 2, the present invention provides an alkali supply pipe 20 ′ which connects the pre-cleaning tank 22 and the cleaning tank 26 through which the strip 1 is flowed from the degreasing tank 10 filled with the degreasing solution 12. And a bypass line 60 connecting the degreasing tank 10 and the brush tank 24 separately from the alkali supply line 20 '.

알카리공급라인(20')상에는 메인펌프(38)와 열교환기(40)가 설치된다.The main pump 38 and the heat exchanger 40 are installed on the alkali supply line 20 '.

상기 메인펌프(38)는 기존과 달리 프리크리닝탱크(22)와 크리닝탱크(26)로만 탈지용액(12)을 공급하면 되므로 그 용량이 충분하다.Unlike the conventional pump 38, the main pump 38 only needs to supply the degreasing solution 12 to the pre-cleaning tank 22 and the cleaning tank 26, so its capacity is sufficient.

상기 열교환기(40)는 기존과 달리 탈지탱크(10)로부터 분리되어 알카리공급라인(20')상에 설치되며, 여기에는 별도의 스팀라인(42)이 연결되어 상기 열교환기(40)를 통과하는 탈지용액(12)을 급속가열시킬 수 있도록 구성된다.Unlike the conventional heat exchanger 40 is separated from the degreasing tank 10 is installed on the alkali supply line (20 '), there is a separate steam line 42 is connected to pass through the heat exchanger (40) It is configured to be able to rapidly heat the degreasing solution (12).

상기 열교환기(40)는 도 3의 도시와 같이, 하우징(41) 내부에 스팀라인(42)이 코일형상으로 수회 절곡배설되도록 함으로써 열교환효율을 극대화시킨 구조이다.As shown in FIG. 3, the heat exchanger 40 has a structure in which the steam line 42 is bent and disposed several times in a coil shape inside the housing 41 to maximize heat exchange efficiency.

상기 열교환기(40)의 인접 상측에는 온도센서(44)가 설치된다.The temperature sensor 44 is installed above the heat exchanger 40.

온도센서(44)의 상측에는 알카리공급라인(20')으로부터 분기되어 리턴라인(50)이 연결되고, 상기 리턴라인(50)은 탈지탱크(10)와 연결된다.The return line 50 is connected to the upper side of the temperature sensor 44 by branching from the alkali supply line 20 ', and the return line 50 is connected to the degreasing tank 10.

또한, 상기 리턴라인(50)에는 리턴솔레노이드밸브(48)가 설치되며, 상기 온도센서(44)에 의해 개폐제어된다.In addition, a return solenoid valve 48 is installed at the return line 50, and is controlled by the temperature sensor 44.

리턴라인(50)이 분기된 상측의 알카리공급라인(20')에는 공급솔레노이드밸브(46)가 설치되며, 상기 공급솔레노이드밸브(46)도 상기 온도센서(44)에 의해 개폐제어된다.The supply solenoid valve 46 is installed in the alkali supply line 20 ′ in which the return line 50 is branched, and the supply solenoid valve 46 is also opened and closed by the temperature sensor 44.

프리크리닝탱크(22)와 크리닝탱크(26)의 하단에는 탈지탱크(10)와 연결된 제1회수배관(70)이 연결된다. A first recovery pipe 70 connected to the degreasing tank 10 is connected to the lower ends of the precleaning tank 22 and the cleaning tank 26.                     

한편, 우회라인(60)에는 보조펌프(62)가 설치되고, 우회라인(60)에 연결된 브러쉬탱크(24)의 하단에는 제2회수배관(72)이 연결되어 탈지탱크(10)와 연결된다.On the other hand, the auxiliary pump 62 is installed in the bypass line 60, the second recovery pipe 72 is connected to the lower end of the brush tank 24 connected to the bypass line 60 is connected to the degreasing tank 10. .

특히, 상기 제2회수배관(72)상에는 이물제거기(80)가 설치된다.In particular, the foreign material remover 80 is installed on the second recovery pipe (72).

상기 이물제거기(80)는 도 4의 도시와 같이, 내부가 중공된 사각형상의 밀폐용기(81)가 구비되고, 상기 밀폐용기(81)의 일부는 격벽(82)에 의해 구획되어 수집함(83)이 형성된다.The foreign material remover 80 is provided with a rectangular sealed container 81 having a hollow inside, as shown in Figure 4, a part of the sealed container 81 is partitioned by the partition 82 to collect (83) ) Is formed.

상기 수집함(83)의 하단면에는 도시하지 않았으나 수집된 이물을 배출하기 위한 배출구가 형성됨이 바람직하다.Although not shown in the bottom surface of the collecting box 83, it is preferable that a discharge port for discharging the collected foreign matter.

상기 격벽(82)의 상단부에는 수집함(83) 대향벽에 구동모터(84)가 설치되고, 상기 구동모터(84)에는 구동풀리(85)가 연결된다.A drive motor 84 is installed at an upper end of the partition 82 and a collector 83 opposite wall, and a drive pulley 85 is connected to the drive motor 84.

상기 구동풀리(85)가 설치된 대향단측 하부, 즉 배출되는 브러쉬탱크(24)의 탈지용액이 밀폐용기(81)로 유입되는 인입측 회수배관(72a)이 연결된 인접 하측에는 종동풀리(86)가 밀폐용기(81)의 양측벽에 회전가능하게 고정된다.The driven pulley 86 is adjacent to the lower side of the opposite end side in which the driving pulley 85 is installed, that is, the lower side adjacent to the inlet side recovery pipe 72a through which the degreasing solution of the brush tank 24 discharged is introduced into the sealed container 81. Is rotatably fixed to both side walls of the hermetic container 81.

아울러, 배출측 회수배관(72b)은 상기 수집함(83)을 우회하여 밀폐용기(81)의 일측면 하단에 연통배설된다.In addition, the discharge side recovery pipe (72b) is bypassed to the collection box 83 is communicated to the lower side of one side of the sealed container (81).

상기 구동풀리(85)와 종동풀리(86)에는 필터(87)가 권취된다.A filter 87 is wound around the drive pulley 85 and the driven pulley 86.

이러한 구성으로 이루어진 본 발명은 다음과 같이 작동된다.The present invention made up of such a configuration works as follows.

메인펌프(38)에 의해 탈지탱크(10)로부터 흡입된 탈지용액(12)은 열교환기(40)를 거치면서 가열되어 알카리공급라인(20')을 타고 이송된다.The degreasing solution 12 sucked from the degreasing tank 10 by the main pump 38 is heated while passing through the heat exchanger 40 and then transported through the alkali supply line 20 '.

이때, 온도센서(44)에 의해 검출된 공급되는 탈지용액(12)의 온도가 75℃ 이 상이면 리턴솔레노이드밸브(48)는 폐쇄되고 공급솔레노이드밸브(46)는 개방되어 프리크리닝탱크(22)와 크리닝탱크(26)로 가열된 탈지용액(12)이 공급되어 세척작용을 행하게 된다.At this time, if the temperature of the supplied degreasing solution 12 detected by the temperature sensor 44 is more than 75 ℃ return solenoid valve 48 is closed and the supply solenoid valve 46 is opened to the pre-cleaning tank 22 The degreasing solution 12 heated to the cleaning tank 26 is supplied to perform a washing action.

만약, 상기 온도센서(44)에서 검출한 탈지용액(12)의 온도가 75℃이하라면 공급솔레노이드밸브(46)는 폐쇄되고 리턴솔레노이드밸브(48)가 개방되어 적정온도로 미가열된 탈지용액(12)는 다시 리턴라인(50)을 타고 탈지탱크(10)로 순환되게 된다.If the temperature of the degreasing solution 12 detected by the temperature sensor 44 is 75 ° C. or less, the supply solenoid valve 46 is closed and the return solenoid valve 48 is opened to unheat the degreasing solution at an appropriate temperature. 12 is circulated back to the degreasing tank 10 by the return line 50.

따라서, 세척을 위해 공급되는 탈지용액의 온도는 항상 75℃ 이상인 상태로 공급되므로 세척작용이 원활하게 수행된다.Therefore, since the temperature of the degreasing solution supplied for washing is always supplied in a state of 75 ° C. or higher, the washing operation is smoothly performed.

한편, 세척과는 무관하게 미리 세척된 스트립(S) 표면을 닦아주는 브러쉬탱크(24)로는 우회라인(60)을 통해 탈지용액(12)이 별도 공급된다.Meanwhile, the degreasing solution 12 is separately supplied through the bypass line 60 to the brush tank 24 which wipes the surface of the strip S previously cleaned regardless of the washing.

상기 브러쉬탱크(24)는 세척작용을 수행하지 않으므로 탈지용액(12)의 온도관리가 필요없다.Since the brush tank 24 does not perform a washing operation, it is not necessary to control the temperature of the degreasing solution 12.

프리크리닝탱크(22) 및 크리닝탱크(26)로 공급된 탈지용액은 사용된 후 제1회수배관(70)을 통해 탈지탱크(10)로 회수되어 재사용되게 되며, 브러쉬탱크(24)로 공급된 탈지용액(12)은 제2회수배관(72)을 통해 회수되는 과정에서 이물제거기(80)를 거치면서 브러쉬칩이나 지분 등이 필터링된 상태로 회수되게 된다.The degreasing solution supplied to the precleaning tank 22 and the cleaning tank 26 is recovered and reused by the degreasing tank 10 through the first recovery pipe 70 after being used, and is supplied to the brush tank 24. The degreasing solution 12 is recovered in a filtered state, such as brush chips or equity while passing through the debris remover 80 in the process of being recovered through the second recovery pipe 72.

즉, 인입측 회수배관(72a)을 통해 밀폐용기(81)로 유입된 이물을 포함한 탈지용액은 회전구동되는 필터(87)에 의해 이물은 걸러지고 순수 탈지용액만 배출측 회수배관(72b)으로 배출되어 탈지탱크(10)로 회수되게 된다. That is, the degreasing solution including the foreign matter introduced into the sealed container 81 through the inlet-side recovery pipe 72a is filtered by the filter 87 which is rotated, and only the pure degreasing solution is discharged to the discharge side recovery pipe 72b. It is discharged and recovered to the degreasing tank 10.                     

필터(87)에 걸러진 이물은 회전되는 필터(87)를 따라 이동되다가 수집함(83)으로 낙하되어 적치되게 되며, 일정량 적치되면 수집함(83)으로부터 배출시켜 별도 처리하게 된다.The foreign material filtered by the filter 87 is moved along the rotating filter 87 and dropped into the collection box 83, and when a predetermined amount is accumulated, it is discharged from the collection box 83 to be separately processed.

이와 같이, 세척을 행하는 탱크와 그렇지 않은 탱크를 구별하여 별도 공급라인을 형성하되, 세척을 행하는 탱크와 연결된 공급라인상에 온도관리기능을 부여함으로써 세척작용을 원활하게 유지함은 물론 이물이 집중적으로 발생되는 브러쉬탱크의 회수배관에는 이물제거기를 설치함으로써 회수된 탈지용액의 재활용율을 극대화시킬 수 있게 된다.In this way, a separate supply line is formed by distinguishing a tank from which the washing is performed with a tank that is not washing, and by providing a temperature control function on the supply line connected to the washing tank, the cleaning operation is smoothly maintained and foreign substances are concentrated. By installing a debris remover in the recovery pipe of the brush tank, the recycling rate of the recovered degreasing solution can be maximized.

이상에서 상세히 설명한 바와 같이, 본 발명은 다음과 같은 효과를 제공한다.As described in detail above, the present invention provides the following effects.

첫째, 프리크리닝탱크와 크리닝탱크 및 브러쉬탱크로 공급되는 탈지용액의 유로를 달리함으로써 펌프의 가동효율을 향상시킨 장점이 있다.First, there is an advantage of improving the operating efficiency of the pump by varying the flow path of the degreasing solution supplied to the pre-cleaning tank, the cleaning tank and the brush tank.

둘째, 프리크리닝탱크와 크리닝탱크로 공급되는 공급배관상에 온도관리기능을 부여함으로써 세척효율을 극대화시킨 장점이 있다.Second, there is an advantage of maximizing the cleaning efficiency by providing a temperature management function on the supply pipe supplied to the pre-cleaning tank and the cleaning tank.

세째, 이물이 집중적으로 발생되는 브러쉬탱크의 회수배관상에 이물제거기를 부가함으로써 탈지용액의 재활용율을 극대화시킨 장점이 있다.Third, there is an advantage of maximizing the recycling rate of the degreasing solution by adding a debris remover on the recovery pipe of the brush tank in which debris is concentrated.
