Description

차압제거기능을 가지는 냉각수 스프레이장치{APPARATUS FOR SPRAYING COOLING WATER WITH A FUNCTION OF SETTLING PRESSURE DISPARITY}Cooling water spray device with differential pressure elimination function {APPARATUS FOR SPRAYING COOLING WATER WITH A FUNCTION OF SETTLING PRESSURE DISPARITY}

본 발명은 차압제거기능을 가지는 냉각수 스프레이장치에 관한 것으로서, 보다 상세하게는 열연공장의 조압연설비와 사상압연설비에 설치되어 열연 제품 상하면 스케일을 제거하기 위하여 고압(200㎏/㎠)의 냉각수를 분사하는 디스켈링 헤더의 노즐에 부착된 필터의 이물질을 자동으로 제거하는 차압제거기능을 가지는 냉각수 스프레이장치에 관한 것이다.The present invention relates to a cooling water spraying device having a differential pressure removing function, and more particularly, installed in a rough rolling facility and a finishing rolling facility of a hot rolling mill to remove a high pressure (200㎏ / ㎠) cooling water to remove scales of hot rolled products. The present invention relates to a cooling water spraying device having a differential pressure removing function for automatically removing foreign matters from a filter attached to a nozzle of a spraying header.

일반적으로, 종래의 기술은 노즐의 필터에 이물이 막혔을 경우 품질에 지대한 결함을 발생시키므로 노즐 필터의 막힘 유무에 관계없이 매주 실시하는 교체휴지 때마다 운전자가 주기적으로 노즐 필터를 청소하게 된다.In general, the conventional technology causes a significant defect in quality when a foreign material is clogged in the filter of the nozzle, so that the driver periodically cleans the nozzle filter at every weekly replacement pause regardless of whether the nozzle filter is blocked.

상기 노즐 필터 청소과정을 설명하면, 디스켈링 헤더의 노즐을 고정하고 있는 캡(Cap)을 분해하여 노즐을 빼내고, 분해된 노즐의 필터를 수거하여 일정한 장소로 이동하여 노즐 필터를 하나씩 와이어 브러시로 스케일은 긁어낸 다음에 고압공기를 이용하여 마무리 청소작업을 시행하며, 이와 병행하여 디스켈링 헤더 내부청결을 유지하기 위해 배관 플로싱(Flushing)을 실시하게 된다.In the process of cleaning the nozzle filter, disassemble the cap holding the nozzle of the descaling header, remove the nozzle, collect the disassembled nozzle filter, move it to a fixed place, and scale the nozzle filter with a wire brush one by one. After scraping off, the final cleaning is performed using high pressure air, and in parallel, the pipe flushing is performed to maintain internal cleaning of the descaling header.

상기한 플로싱 작업은 노즐을 조립한 상태에서 실시하면 청소된 필터에 이물질이 부착되므로 노즐이 없는 상태에서 디스켈링 밸브(Spray Valve)를 강제로 열어 고압(200㎏/㎠) 플로싱을 실시하며, 플로싱이 완료된 다음에 청소된 노즐을 현장으로 가져가서 디스켈링 헤더에 노즐을 끼워서 캡으로 고정하면 필터노즐 청소작업이완료된다.When the above-mentioned flocculation work is carried out in the state of assembling the nozzle, foreign matters are attached to the cleaned filter, so that the high pressure (200㎏ / ㎠) flows by forcibly opening the spray valve in the absence of the nozzle. After the flow is completed, take the cleaned nozzle to the site, insert the nozzle into the descaling header and secure it with a cap to complete the cleaning of the filter nozzle.

이와 같은 과정을 수행하기 위해서는 짧은 시간에 많은 작업을 병행하기 위해서 인력이 분산되어 각각의 작업을 분업을 해야 하므로 작업능률이 저하되며 작업자 개개인이 재해에 취약하다는 단점이 있었다.In order to perform such a process, in order to perform many tasks in parallel in a short time, the workforce must be divided and each work must be divided so that work efficiency is deteriorated and individual workers are vulnerable to disaster.

상기한 종래기술의 문제점을 해결하기 위하여, 본 발명은 디스켈링 헤더노즐의 필터에 부착된 이물질 제거를 위해 인위적인 힘을 가하지 않고 필터 노즐에 부착된 이물질의 제거와 배관 내부의 플로싱 작업이 자동으로 되도록 하는 차압제거기능을 가지는 냉각수 스프레이장치를 제공하는데 그 목적이 있다.In order to solve the above problems of the prior art, the present invention is to automatically remove the foreign matter attached to the filter nozzle and the flocculation work inside the pipe without applying artificial force to remove the foreign matter attached to the filter of the descaling header nozzle. It is an object of the present invention to provide a cooling water spray device having a differential pressure removing function.

The foreign material attached to the internal channels 52a, 52b, 52c, 52x, 52y, and 52z of the main body 1 is pushed out of the main body 1, and then the inner surface of the main body 1 and the spools 2a, 2b and 2c. , 2x, 2y, 2z are completely in contact, the spools 2a, 2b, 2c, 2x, 2y, 2z do not operate any more.

이때 스프링 내장형 실린더(11a, 11b, 11y, 11z)를 계속 동작 시키면, 스풀(2a, 2b, 2c, 2x, 2y, 2z)이 본체(1)를 고정한 다음, 본체(6)를 스프링 내장형 실린더(11a, 11b, 11y, 11z) 이동거리 만큼 주축으로 끌어 올리게 되고,At this time, if the spring-loaded cylinders (11a, 11b, 11y, 11z) continue to operate, the spools (2a, 2b, 2c, 2x, 2y, 2z) fix the body (1), and then the body (6) is a spring-loaded cylinder ( 11a, 11b, 11y, 11z) will be pulled up to the main axis by the travel distance,

디스켈링 배관(13)에 형성된 노즐구(14)와 노즐본체(1)와는 일정한 틈새가 발생되며, 벌어진 틈새로 본체(1)의 내부수로(52a, 52b, 52c, 52x, 52y, 52z)에서 스풀(2a, 2b, 2c, 2x, 2y, 2z)의 동작으로 밀려난 이물질이 디스켈링 배관(13)의 외부로 배출하여 이물질 제거와 플로싱 작업을 실시한다.A certain gap is generated between the nozzle port 14 and the nozzle body 1 formed in the desqueling pipe 13, and the gaps are formed in the inner channels 52a, 52b, 52c, 52x, 52y, and 52z of the main body 1. Foreign matter pushed out by the operation of the spool (2a, 2b, 2c, 2x, 2y, 2z) is discharged to the outside of the descaling pipe (13) to perform the foreign matter removal and flotation.

이물질 제거와 플로싱(Freshing) 작업이 끝나면, 전자밸브(12)가 공기의 공급을 차단하게 되고, 스프링 내장형 실린더(11a, 11b, 11y, 11z)는 공기의 힘이 없어져 내장된 스프링의 힘으로 스풀이 복원하게 되고, 이와 연결된 주축(6)도 아래 방향으로 내려가면서 본체(1)의 주축(6)과 같이 내려가 디스켈링 배관(13)의 노즐구(14)와 밀착하여 외부로 유출되던 냉각수를 차단하게 된다.After the removal of foreign substances and the flushing operation, the solenoid valve 12 shuts off the air supply, and the spring-loaded cylinders 11a, 11b, 11y, and 11z lose the air force and are driven by the force of the built-in spring. The spool is restored, and the main shaft 6 connected thereto is also lowered and moved down along with the main shaft 6 of the main body 1 to be in close contact with the nozzle port 14 of the descaling pipe 13 and flowed out to the outside. Will block.

이때 상기 스프링 내장형 실린더(11a, 11b, 11y, 11z)가 스프링의 힘으로 계속 동작하면 본체(1)가 디스켈링 배관(13)의 노즐구(14)에 닿아 더 이상 밀려갈 수 없게 되면, 주축(6)에 연결된 링크(4a, 4b, 4c, 4x, 4y, 4z)가 스풀(2a, 2b, 2c, 2x, 2y, 2z)을 후퇴시켜 본 발명의 이물질 자동제거장치의 한 행정이 종료된다.At this time, if the spring-loaded cylinders (11a, 11b, 11y, 11z) continue to operate with the force of the spring, the main shaft (1) is in contact with the nozzle port 14 of the descaling pipe (13) can not be pushed further, the main shaft The link 4a, 4b, 4c, 4x, 4y, 4z connected to (6) retracts the spools 2a, 2b, 2c, 2x, 2y, 2z so that one stroke of the automatic debris removal device of the present invention is terminated. .

상술한 바와 같이, 본 발명은 디스켈링 배관의 노즐구에 부착된 이물질의 제거를 위해 배관 내의 압력을 지속적으로 검출하여 설정압력보다 낮을 경우 본 발명의 이물질 제거장치를 작동시켜 이물질을 노즐몸체의 외부로 밀어내고, 제거된 이물질을 고압수로 디스케일링 배관 밖으로 연속적인 자동 배출함으로써 디스케일 배관의 이물질 제거와 플로싱 작업을 병행하여 품질향상과 작업자의 재해를 방지할 수 있다는 장점이 있다.As described above, the present invention continuously detects the pressure in the pipe to remove the foreign matter adhering to the nozzle port of the desqueling pipe and operates the foreign material removal device of the present invention when the pressure is lower than the set pressure, thereby removing the foreign matter from the outside of the nozzle body. By removing the foreign matter from the descaling pipe and continuously discharging the foreign matter from the descaling pipe with high pressure water, it is possible to improve the quality and prevent worker's disaster.
