연마유 미스트 회수장치{RECYCLING DEVICE OF OIL MIST}Abrasive oil mist recovery unit {RECYCLING DEVICE OF OIL MIST}

본 발명은 스트립연마기에 관한 것으로, 특히 스트립연마기의 연마유 미스트를 회수하는 연마유 미스트 회수장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strip polishing machine, and more particularly, to an abrasive mist recovery device for recovering an abrasive mist of a strip polishing machine.

일반적으로 스테인레스공장의 소둔산세공정에서는 스트립의 표면결함을 제거하고 스트립 표면의 조도 및 광택을 부여하기 위하여 다수개의 스트립연마기가 설치되어 스트립의 표면을 연마하게 된다.In general, in the annealing and pickling process of the stainless plant, a plurality of strip grinding machines are installed to remove the surface defects of the strip and to give the surface roughness and gloss.

이러한 스트립연마기는 콘텍트롤과 텐션롤에 연마벨트가 권취되어 고속으로 회전하면서 스트립표면을 연마하게 되는데 마찰열을 식혀주고 연마의 효율을 높이기 위하여 연마유를 스트립의 표면에 분사해준다.The strip grinder is wound around the surface of the strip while the polishing belt is wound around the contact and tension roll to rotate at high speed. The abrasive is sprayed on the surface of the strip to cool the frictional heat and increase the efficiency of polishing.

종래기술에 따른 스트립연마기를 도 3을 이용하여 상세히 설명한다.Strip grinding machine according to the prior art will be described in detail with reference to FIG.

스트립연마기에서는 연마벨트(82)가 콘텍트롤(84)과 텐션롤(86)에 권취되어 고속으로 회전되고 스트립을 사이에 두고 빌리롤(88)이 설치되어 스트립을 지지하므로 스트립의 표면이 연마된다. 또한 스트립연마기의 내부에 연마유노즐(90)이 설치되어 스트립의 표면에 연마유를 분사하게 된다. 따라서 스트립연마기는 연마유의 비산을 방지하기 위하여 연마캐빈(80)이 설치된다.In the strip polishing machine, the polishing belt 82 is wound around the contact point 84 and the tension roll 86, rotates at high speed, and the bilirol 88 is installed to support the strip with the strip sandwiched therebetween, thereby polishing the surface of the strip. . In addition, an abrasive oil nozzle 90 is installed inside the strip polisher to spray the abrasive oil onto the surface of the strip. Therefore, the strip polishing machine is provided with an abrasive cabin 80 to prevent the scattering of the abrasive oil.

그러나 연마캐빈의 스트립 인입구와 입출구를 통하여 연마유 미스트가 비산되므로 작업장주위가 미끄러워 안전사고를 발생시킬 수 있는 문제점이 있다.However, since the abrasive mist is scattered through the strip inlet and the inlet and outlet of the polishing cabin, there is a problem that a safety accident may occur due to the slipping around the workplace.

또한 연마유 미스트가 작업자의 피부에 직접 접촉되므로 작업자에게 피부병을 유발시킬 수 있는 문제점이 있다.In addition, there is a problem that can cause the skin disease to the worker because the abrasive oil directly contacts the operator's skin.

이에 본 발명의 상기한 문제점을 해결하기 위하여 안출된 것으로 작업장 주위로 연마유가 비산되는 것을 방지하는 연마유 미스트 회수장치를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide an abrasive mist recovery device for preventing abrasive oil from being scattered around a work place, which is devised to solve the above problems of the present invention.

In addition, a gate 16 is provided at the opening on the cabin door 52 side, and a drive cylinder 18 for moving the gate is mounted on the side of the mist duct 10. On the other hand, the side of the cabin door 52 is provided with a sensor 20 so as to detect the opening and closing of the cabin door 52. Therefore, the signal generated from the sensor 20 is sent to the control unit 48 and is calculated by the control unit 48 to control the driving cylinder 18, so that the gate 16 is opened and closed.

집진덕트(12)는 일단은 미스트덕트(10)에 연결되고 타단은 확장되어 확장블록(22)이 형성되며 이 확장블록(22)의 일측면은 필터(34)가 삽입될수 있도록 개구되어 있다. 또한 이 확장블록(22)은 하단으로 축소되어 분지되는데 분지된 일측으로는 진공수단(14)이 연결되고 하측으로는 연마유 낙하관(24)이 설치된다. 따라서 분지된 일측의 진공수단(14)에 의해 집진덕트(12)와 미스트덕트(10)에 부압이 형성되어 연마유더스트가 흡입되고 분지된 타측의 연마유 낙하관(24)을 따라 응결된 연마유가 낙하되어 재순환된다. 한편 집진덕트(12)의 중간에 제1측압센서(26a)가 설치되어 집진덕트(12)내의 압력을 감지한다.The dust collecting duct 12 has one end connected to the mist duct 10 and the other end extended to form an expansion block 22, and one side of the expansion block 22 is opened to allow the filter 34 to be inserted. In addition, the expansion block 22 is branched by being reduced to the lower end, the branched one side is connected to the vacuum means 14, the lower side is provided with an abrasive oil drop tube 24. Accordingly, negative pressure is formed in the dust collecting duct 12 and the mist duct 10 by the vacuum means 14 on one side of the branched side, and the abrasive oil dust is sucked in and the condensation along the other abrasive oil dropping tube 24 is branched. The oil drops and is recycled. Meanwhile, the first side pressure sensor 26a is installed in the middle of the dust collecting duct 12 to sense the pressure in the dust collecting duct 12.

진공수단(14)은 집진덕트(12)의 하부에 설치되는 케이싱(28), 케이싱(28)에 수용되어 회전하는 팬(30), 상기 팬(30)을 회전시키는 구동모터(32)로 이루어진다.The vacuum means 14 is composed of a casing 28 installed in the lower portion of the dust collecting duct 12, a fan 30 accommodated in the casing 28 to rotate, and a drive motor 32 for rotating the fan 30. .

케이싱(28)은 집진덕트(12)의 하부에 설치되며 케이싱(28)의 일단에는 집진덕트(12)의 확장블록(22)에 연결되는 흡입관(28a)이 설치되고 타단에는 구동모터(32)의 회전축이 회전할 수 있도록 베어링부재가 설치되며 반경방향으로 토출관(28b)이 설치된다. 한편 흡입관(28b)에는 제2측압센서(26b)가 설치되어 흡입관(28b) 내부의 압력을 감지한다.The casing 28 is installed at the lower portion of the dust collecting duct 12, and one end of the casing 28 is provided with a suction pipe 28a connected to the expansion block 22 of the dust collecting duct 12, and the other end of the driving motor 32. The bearing member is installed so as to rotate the rotating shaft of the discharge tube 28b is installed in the radial direction. Meanwhile, a second side pressure sensor 26b is installed at the suction pipe 28b to detect the pressure inside the suction pipe 28b.

팬(30)은 케이싱(28)의 내부에 회전가능하도록 설치되며 일측에 형성된 구동모터(32)에 의해 회전되어 미스트덕트(10)와 집진덕트(12)의 내부에 부압을 형성시킨다. 따라서 연마유 미트스가 팬(30)에서 발생된 부압에 의해 미스트덕트(10)를 통하여 흡입된다.The fan 30 is rotatably installed in the casing 28 and is rotated by the drive motor 32 formed on one side to form a negative pressure in the mist duct 10 and the dust collecting duct 12. Therefore, the abrasive oil mist is sucked through the mist duct 10 by the negative pressure generated in the fan 30.

구동모터(32)는 케이싱(28)의 일측에 설치되며 축이음(32a)에 의해서 팬(30)에 연결되고 하부에는 베이스(32b)가 설치되어 구동모터(32)를 지면에 고정시킨다.The drive motor 32 is installed on one side of the casing 28 and is connected to the fan 30 by the shaft joint 32a, and the base 32b is installed at the bottom to fix the drive motor 32 to the ground.

다음으로 여과부는 집진덕트(12)의 중간에 착탈될 수 있도록 설치된 필터(34), 필터(34)를 슬라이딩시켜 착탈시키는 필터실린더(36), 필터(36)의 하부에 설치되어 에어를 분사하는 에어노즐(38), 에어노즐(38)에 의해 배출된 연마유의 이물질을 수용하도록 설치된 드레인블록(40)으로 이루어진다.Next, the filter unit is installed at a filter 34 installed to be detachable in the middle of the dust collecting duct 12, a filter cylinder 36 sliding and detaching the filter 34, and a lower portion of the filter 36 to inject air. The air nozzle 38 and the drain block 40 installed to receive foreign matter of the abrasive oil discharged by the air nozzle 38.

필터(34)는 집진덕트(12)의 하단에 형성된 확장블록(22)에 삽입설치되며 일측면에는 필터실린더(36)의 피스톤로드가 결합되어 필터실린더(36)의 작동에 의해 확장블록(22)을 가로질러 착탈된다. 따라서 필터(34)는 연마유 미스트속의 이물질을 제거하며 동시에 연마유 미스트가 필터(34)와 충돌하여 응결되어 연마유 낙하관(24)을 통하여 낙하된다. 한편 이 연마유 낙하관(24)을 통하여 낙하된 연마유는 수집조(42)에 일시수용된 후 회수관(44)을 통하여 재순환된다.The filter 34 is inserted into the expansion block 22 formed at the lower end of the dust collecting duct 12 and the piston rod of the filter cylinder 36 is coupled to one side thereof, and the expansion block 22 is operated by the operation of the filter cylinder 36. Detached across). Therefore, the filter 34 removes foreign matter in the abrasive oil mist and at the same time, the abrasive oil mist collides with the filter 34 to condense and fall through the abrasive oil drop tube 24. On the other hand, the abrasive oil dropped through the abrasive oil drop tube 24 is temporarily accommodated in the collection tank 42 and then recycled through the recovery tube 44.

필터실린더(36)는 확장블록(22)에 일측으로 연장설치된 필터블록(46)에 설치되며 필터(34)가 확장블록(22)과 필터블록(46)을 슬라이딩하게 한다.The filter cylinder 36 is installed in the filter block 46 extending to one side of the expansion block 22 and allows the filter 34 to slide the expansion block 22 and the filter block 46.

에어노즐(38)은 필터블록(46)의 하부에서 에어를 상방으로 분사하도록 설치된다. 따라서 필터실린더(36)에 의해서 필터(34)가 인출되면 에어노즐(38)이 작동되어 에어를 필터(34)로 분사하므로 필터에 붙어있는 연마유의 이물질이 배출된다. 여기서 필터(34)의 인출은 집진덕트(12)에 설치된 제1측압센서(26a)와 케이싱(28)의 흡입관(28a)에 설치된 제2측압센서(26b)로부터 수신된 신호를 제어부(48)에서 연산하여 필터(34)의 인출여부를 결정하게 된다. 즉 필터(34)에 이물질이 쌓이면 진공수단(14)과 집진덕트(12)의 사이가 차단되어 제1측압센서(26a)의 압력이 상승하게 되므로 측압센서(26a,26b)간의 압력차이가 커져 필터(34)의 인출을 결정하게 된다.The air nozzle 38 is installed to inject air upward from the bottom of the filter block 46. Therefore, when the filter 34 is drawn out by the filter cylinder 36, the air nozzle 38 is operated to inject air into the filter 34, thereby removing foreign matters from the abrasive oil attached to the filter. The extraction of the filter 34 is performed by controlling the signal received from the first side pressure sensor 26a installed in the dust collecting duct 12 and the second side pressure sensor 26b provided in the suction pipe 28a of the casing 28. It is determined by operation of the filter 34 to calculate the. That is, when foreign matters accumulate on the filter 34, the gap between the vacuum means 14 and the dust collecting duct 12 is blocked, so that the pressure of the first side pressure sensor 26a is increased, so that the pressure difference between the side pressure sensors 26a and 26b becomes large. The withdrawal of the filter 34 is determined.

드레인브록(40)은 필터블록(46)의 일측으로 연장설치되어 에어노즐(38)의 분사에 의해 필터(34)로부터 배출된 연마유의 이물질을 수용하게 된다.The drain block 40 extends to one side of the filter block 46 to receive foreign matters of abrasive oil discharged from the filter 34 by the injection of the air nozzle 38.

이하 본 발명의 작동에 대해 설명하면 다음과 같다.Hereinafter will be described the operation of the present invention.

본 발명에 따른 연마유 미스트의 회수장치는 먼저 구동모터(32)를 작동시켜 팬(30)을 회전시키면 팬(30)의 내부에 부압이 형성되고 점차적으로 집진덕트(12)와 미스트덕트(10)의 내부에도 부압이 형성된다.In the recovery device of the abrasive oil mist according to the present invention, when the fan 30 is rotated by operating the driving motor 32, negative pressure is formed inside the fan 30, and the dust collecting duct 12 and the mist duct 10 are gradually formed. Negative pressure is also formed inside.

집진덕트(12)와 미스트덕트(10)에 부압이 형성되면 연마기를 작동시켜 스트립을 연마하게 되면 연마캐빈(50)의 스트립 인입구와 인출구로 연마유 미스트가 비산된다. 이렇게 비산된 연마유 미스트는 미스트덕트(10)에 형성된 부압 때문에 미스트덕트(10)에 흡입되어 집진덕트(12)로 이송된다.When negative pressure is formed in the dust collecting duct 12 and the mist duct 10, the polishing machine is operated to polish the strip so that the polishing oil mist is scattered to the strip inlet and the outlet of the polishing cabin 50. The abrasive oil mist scattered in this way is sucked into the mist duct 10 due to the negative pressure formed in the mist duct 10 and is transferred to the dust collecting duct 12.

연마캐빈(50)의 상부에 설치된 게이트(16)의 작동은 연마캐빈(50)의 캐빈도어(52)를 열면 캐빈도어(52)의 측면에 부착된 감지센서(20)에 의해 제어부(48)로 신호가 송신되고 제어부(48)에서 연산되어 게이트(16)의 상부에 설치된 실린더(18)를 작동시켜 게이트(16)를 열게된다. 따라서 캐빈도어(52)를 통하여 방출되는 연마유 미스트는 미스트덕트(10)의 개구부를 통하여 미스트덕트(10)에 흡입되어 집진덕트(12)로 이송된다.Operation of the gate 16 installed on the upper part of the polishing cabin 50 opens the cabin door 52 of the polishing cabin 50 by the sensor 48 attached to the side of the cabin door 52 by the control unit 48. The low signal is transmitted and calculated by the controller 48 to operate the cylinder 18 installed above the gate 16 to open the gate 16. Therefore, the abrasive mist discharged through the cabin door 52 is sucked into the mist duct 10 through the opening of the mist duct 10 and is transferred to the dust collecting duct 12.

집진덕트(10)로 이송된 연마유 미스트는 필터(34)를 통과하게 된다. 여기서 연마유 미스트의 이물질은 필터(34)를 통과하지 못하므로 필터(34)의 표면에 부착된다. 또한 연마유 미스트는 필터(34)의 망에 충돌하며 응결되는 웨팅(Wetting)현상에 의해 액체로 되어 연마유 낙하관(24)을 따라 수집조(42)에 낙하되어 회수관(44)을 통하여 재순환 된다.The abrasive oil mist transferred to the dust collecting duct 10 passes through the filter 34. Here, foreign matter of the abrasive oil mist does not pass through the filter 34, and thus is attached to the surface of the filter 34. In addition, the abrasive mist is a liquid by the wetting phenomenon that collides with the network of the filter 34, and is dropped into the collection tank 42 along the abrasive drop tube 24, through the recovery tube 44 Recycled.

필터(34)에 부착된 이물질이 많아지면 유로가 좁아지게 된다. 따라서 집진덕트(12)에 설치된 제1측압센서(26a)와 케이싱(28)의 흡입관(28a)에 설치된 제2측압센서(26b)의 압력차가 커지므로 두 측압센서(26a,26b)의 압력차를 제어부(48)에서 감지하여 필터실린더(36)를 작동시키게 된다.If the foreign matter attached to the filter 34 increases, the flow path is narrowed. Therefore, since the pressure difference between the first side pressure sensor 26a provided in the dust collecting duct 12 and the second side pressure sensor 26b provided in the suction pipe 28a of the casing 28 increases, the pressure difference between the two side pressure sensors 26a and 26b. Is detected by the controller 48 to operate the filter cylinder 36.

필터실린더(36)가 작동되어 필터(34)가 필터블록(46)으로 인출되면 필터블록(46)의 하부에 설치된 에어노즐(38)에 에어가 공급되어 필터(34)에 부착된 이물질을 드레인블록(40)으로 배출시키게 된다.When the filter cylinder 36 is operated and the filter 34 is drawn out to the filter block 46, air is supplied to the air nozzle 38 installed at the lower part of the filter block 46 to drain foreign substances attached to the filter 34. To the block 40.

이상 설명한 바와 같은 본 발명에 따른 연마유 미스트의 회수장치는 연마유 미스트의 비산이 방지되므로 작업장 주변이 미끄럽지 않게 되므로 안전사고를 예방할 수 있다.Since the recovery device of the abrasive oil mist according to the present invention as described above is prevented from scattering of the abrasive oil mist, it is possible to prevent safety accidents because the periphery of the workplace is not slippery.

또한 연마유 미스트의 비산이 방지되므로 작업자의 피부에 연마유 미스트가직접 접촉되어 발생되는 피부병을 방지하므로 작업환경이 개선된다.In addition, since the abrasive mist is prevented from scattering, it prevents skin diseases caused by the direct contact of the abrasive mist with the operator's skin, thereby improving the working environment.
