분사노즐의 막힘 방지 기능을 구비한 분사시스템{Equipped with anti-clogging of the spray nozzle injection system}Equipped with anti-clogging of the spray nozzle injection system

본 발명은 각종 산업현장에서 용수나 화학약품 등을 목적물에 분사하는데 사용하는 분사노즐의 막힘 방지 기능을 구비한 분사시스템에 관한 것으로, 특히 퇴적물이나 약품 등의 건고 또는 용수 중의 경도성분 등에 의하여 분사공이 서서히 막히는 현상을 방지하도록 한 분사노즐의 막힘 방지 기능을 구비한 분사시스템에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spraying system having a function of preventing clogging of a spray nozzle used for spraying water or chemicals to a target object in various industrial sites, and particularly, injecting holes by dry matter such as deposits or chemicals or hardness components in water. The present invention relates to an injection system provided with a clogging prevention function of an injection nozzle, which prevents the phenomenon of clogging gradually.

일반적으로 노즐은 각종 산업분야의 생산공장 또는 폐수처리공장 등에서 여러 가지 목적으로 고압의 용수 또는 화학약품을 분사시키고자 하는 목적으로 사용하는바, 그 크기와 모양이 매우 다양하며 필요에 따라 용도 및 목적에 적합한 것으로 선택하여 사용한다.In general, nozzles are used for the purpose of spraying high pressure water or chemicals for various purposes in production plants or wastewater treatment plants in various industrial fields, and their sizes and shapes vary widely. Select the appropriate one for use.

그러나 상기와 같은 목적으로 사용되는 노즐을 장시간 사용하거나 노즐을 통한 분사를 수시로 중단 및 재개할 경우 용수나 화학약품을 분사시켜주는 분사공이 용수나 화학약품을 공급해주는 배관내의 퇴적물이나, 화학약품의 건고 또는 용수중의 경도성분 등에 의하여 서서히 막히게 되어 목적물에 용수나 화학약품 등을 공급하지 못하는 문제점으로 인해 작업에 막대한 지장을 초래하게 되었다.However, when the nozzle used for the above purpose is used for a long time or the spraying through the nozzle is interrupted and resumed frequently, the dryness of the deposits or chemicals in the pipe supplying the water or the chemical is provided by the injection hole for spraying the water or the chemical. Or it is gradually blocked by the hardness component in the water and caused a huge obstacle to the operation due to the problem of not supplying water or chemicals to the target.

상기와 같은 문제점의 일예로써 금속세정공장에서 금속표면을 깨끗이 세정할 목적으로 순수를 분사시켜주는 노즐의 분사공이 막히게 되는 경우 금속표면이 이물질이나 다른 약품들의 의해 산화 또는 변색이 발생하여 최종 제품에 불량을 초래하게 되는 문제점이 있다.As an example of the above problems, if the injection hole of the nozzle that sprays pure water for the purpose of cleaning the metal surface in the metal washing plant is blocked, the metal surface is oxidized or discolored by foreign substances or other chemicals, resulting in defects in the final product. There is a problem that causes.

또한 상기 노즐이 막히게 되면 설비를 휴지하고 노즐을 분해하여 막힌 분사공을 수리한 후 개공시켜 준 다음 이를 다시 결합하여 설비를 가동시켜야 함으로써 설비휴지에 따른 생산성 저하와, 노즐의 분해 결합에 따른 번거로움 등이 초래하였다.
In addition, when the nozzle is clogged, the equipment is stopped, the nozzle is disassembled, the clogged injection hole is repaired and then opened, and then it is required to be combined again to operate the equipment. And so on.

상기와 같은 제반 문제점을 감안하여 이를 해소하고자 안출한 본 발명의 목적은 분사 정지시에는 일정시간 경과 후에 압축공기만을 분사한 후 정지하도록 함으로서 작업 완료 후에 관로에 남아 있는 유체를 회수하고 또한 일정시간 압축공기만을 분사하도록 하여 관로에 남아있거나 노즐 표면에 묻어 있는 잔류 유체를 배출시켜 노즐의 분사공 막힘을 해소할 수 있도록 한 분사노즐의 막힘방지 기능을 구비한 분사시스템을 제공하는데 있다.
The object of the present invention devised to solve the above problems is to recover the fluid remaining in the conduit after the completion of the work by compressing only the compressed air after a certain period of time when the injection stops, and also compresses for a certain time. It is to provide an injection system having a function of preventing the clogging of the nozzle to inject only the air to discharge the residual fluid remaining in the pipe or buried in the nozzle surface to solve the clogging of the nozzle.

상기 상기 분사정지시 펌프수단을 역회전시켜 공급되던 유체를 저장수단으로 회수하도록 한 후 일정시간 경과 후 유체공급조절수단을 정지시키고 유체공급조절수단의 정지 후 일정시간이 경과 되면 펌프수단 및 압축공기생성수단을 정지시키는 것을 특징으로 하는 분사노즐의 막힘 방지 기능을 구비한 분사시스템에 의하여 달성된다.
When the injection stops, the pump means is rotated in reverse to recover the supplied fluid to the storage means, and then, after a certain time, the fluid supply control means is stopped, and after a certain time elapses after the stop of the fluid supply control means, the pump means and the compressed air It achieves by the injection system provided with the clogging prevention function of the injection nozzle characterized by stopping the generating means.

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도 1은 본 발명의 기술이 적용된 분사노즐의 막힘방지 기능을 구비한 분사시스템의 구성을 보여주는 구성도로서 이에 따르면 본 발명은 전원의 공급 및 차단을 조절하는 마이콤수단(300)에는 압축공기를 생성시키는 압축공기생성수단(200)과 액체를 저장하는 저장수단(400)이 연결 설치되며, 상기 압축공기생성수단(200)에는 공기공급관(800)에 의해 분사노즐(100)에 연결 설치된다. 1 is a block diagram showing the configuration of an injection system having a clogging prevention function of an injection nozzle to which the technique of the present invention is applied. According to the present invention, the present invention provides a compressed air for controlling the supply and interruption of power. Compressed air generating means for generating a 200 and the storage means for storing the liquid 400 is connected is installed, the compressed air generating means 200 is connected to the injection nozzle 100 by an air supply pipe 800 is installed .

한편 상기 분사노즐(100)과 유체가 저장되는 저장수단(400)을 연결하는 유체공급관(700)의 일정 부위에 설치되어 유체를 강제이송시키는 펌프수단(500)이 설치되되, 상기 유체와 압축공기를 분사하는 노즐이 구비된 분사노즐(100)과 펌프수단(500) 사이에는 상기 마이콤수단(300)과 연결되어 분사노즐(100)로 이송되는 유체의 공급 및 차단을 조절하는 유체공급조절수단(600)이 설치된다.Meanwhile, the pump means 500 is installed at a predetermined portion of the fluid supply pipe 700 connecting the injection nozzle 100 and the storage means 400 for storing the fluid, and the pump means 500 for forcibly transferring the fluid is installed. Between the injection nozzle 100 and the pump means 500 is provided with a nozzle for spraying the fluid supply control means connected to the microcomputer means 300 to control the supply and shutoff of the fluid transferred to the injection nozzle 100 ( 600) is installed.

상기와 같이 이루어진 본 발명의 작동은 먼저 마이콤수단(300)에 연결된 압축공기생성수단(200), 펌프수단(500) 및 유체공급조절수단(600)에 전원을 공급하여 작동시킨다.Operation of the present invention made as described above is operated by supplying power to the compressed air generating means 200, the pump means 500 and the fluid supply control means 600 connected to the first microcomputer means (300).

상기 압축공기생성수단(200), 펌프수단(500) 및 유체공급조절수단(600)이 작동되면 압축공기생성수단(200)에서 압축공기가 생성되며 생성된 압축공기는 공기공급관(800)을 통하여 분사노즐(100)에 의해 분사된다.When the compressed air generating means 200, the pump means 500 and the fluid supply control means 600 is operated, compressed air is generated in the compressed air generating means 200, and the generated compressed air is provided through the air supply pipe 800. It is injected by the injection nozzle 100.

이때 상기 유체가 저장되어 있는 저장수단(400)의 유체는 압축공기생성수단(200)과 동시에 펌프수단(500)에 의하여 강제적으로 유체공급관(700)을 통해 분사노즐(100)로 이송하여 압축공기와 혼합되어 저장수단(400)에 저장된 유체와 같이 분사된다.At this time, the fluid of the storage means 400 in which the fluid is stored is forcibly transferred to the injection nozzle 100 through the fluid supply pipe 700 by the pump means 500 at the same time as the compressed air generating means 200 and compressed air And is injected together with the fluid stored in the storage means (400).

한편 분사가 완료되면 분사를 정지시키게 되는데 이때 마이콤수단(300)을 이용하여 시스템을 정지시키면 펌프수단(500)이 일정시간 역회전을 하여 분사노즐(100)로 이송되는 유체공급관(700) 내부에 잔류하는 유체를 저장수단(400)으로 회수시킨다.Meanwhile, when the injection is completed, the injection is stopped. At this time, when the system is stopped using the microcomputer means 300, the pump means 500 rotates in a reverse direction for a predetermined time, and is inside the fluid supply pipe 700 which is transferred to the injection nozzle 100. The remaining fluid is recovered to the storage means 400.

따라서 유체공급관(700)의 관로 상에는 잔류하는 유체가 잔존하지 않고 저장수단(400)으로 회수되기 때문에 시스템의 재사용시보다 깨끗한 상태로 재사용할 수 있게 된다.Therefore, since the remaining fluid is recovered to the storage means 400 without remaining in the pipeline of the fluid supply pipe 700, it can be reused in a cleaner state than when the system is reused.

한편 마이콤수단(300)의 분사정지 명령에 의해 상기 펌프수단(500)의 일정시간 역회전 작동시 상기한 압축공기생성수단(200)도 일정시간 작동하게 된다.On the other hand, when the reverse rotation of the pump means 500 by the injection stop command of the microcomputer means 300, the compressed air generating means 200 is also operated for a predetermined time.

따라서 분사노즐(100)에서는 마이콤수단(300)의 분사정지 명령에 의해 공급되던 유체는 회수되며 압축공기생성수단(200)도 일정시간 작동하여 공기공급관(800)을 통하여 분사된다.Therefore, in the injection nozzle 100, the fluid supplied by the injection stop command of the microcomputer means 300 is recovered, and the compressed air generating means 200 also operates for a predetermined time and is injected through the air supply pipe 800.

즉, 유체와 압축공기가 혼합되어 분사되던 분사노즐(100)에서는 압축공기만 일정시간 분사되어 분사노즐(100) 내에 잔류하는 유체를 전부 토출시키게 된다.That is, in the injection nozzle 100 in which the fluid and the compressed air are mixed and injected, only the compressed air is injected for a predetermined time to discharge all the fluid remaining in the injection nozzle 100.

한편 상기 압축공기생성수단(200)과 펌프수단(500)이 분사정지 명령에 의해 각각 일정시간 작동하게 되면 유체공급조절수단(600)이 정지하게 되며 상기 유체공급조절수단(600)의 정지 후 일정시간 경과 후 압축공기생성수단(200)과 펌프수단(500)이 완전 정지하게 된다.Meanwhile, when the compressed air generating means 200 and the pump means 500 operate for a predetermined time by the injection stop command, respectively, the fluid supply control means 600 is stopped, and after the stop of the fluid supply control means 600, After the passage of time, the compressed air generating means 200 and the pump means 500 are completely stopped.

본 발명은 분사 정지시에는 유체공급관 내의 유체를 저장수단으로 회수하도록 하고 일정시간 동안 압축공기만을 분사후 정지하도록 함으로서 관로에 남아있거나 노즐 표면에 묻어 있는 잔류 유체를 배출시켜 노즐의 분사공 막힘을 해소할 수 있도록 하는 이점이 있다.
In the present invention, when the injection stops, the fluid in the fluid supply pipe is recovered to the storage means, and only the compressed air is injected after stopping for a predetermined period of time, thereby discharging the residual fluid remaining in the pipe or buried in the nozzle surface to eliminate the clogging of the nozzle. There is an advantage to this.
