Description

분사노즐용 하우징 및 이를 이용한 2유체 분사장치Housing for injection nozzle and two-fluid injection device using the same
본 발명은 분사노즐용 하우징 및 이를 이용한 2유체 분사장치에 관한 것으로서, 보다 상세하게는 헤드가 결합되는 부위의 강도가 저하되는 것을 방지하고, 유압차에 의한 유체의 역류를 방지할 수 있도록 하는 분사노즐용 하우징 및 이를 이용한 2유체 분사장치에 관한 것이다.The present invention relates to a housing for injection nozzles and a two-fluid injection device using the same, and more particularly, injection to prevent the strength of the portion to which the head is coupled from being lowered and to prevent backflow of fluid by a hydraulic vehicle. It relates to a nozzle housing and a two-fluid injection device using the same.
일반적으로, 노즐은 액체를 분무하기 위하여 사용하는 것으로, 분무되는 액체가 공기와 혼합되는 위치에 따라 내부 혼합식 분무 노즐과 외부 혼합식 분무 노즐로 구분할 수 있다. 이러한 노즐은 산업 전반에 걸쳐 다양한 분야에서 사용되고 있다.In general, the nozzle is used to spray the liquid, it can be divided into the internal mixed spray nozzle and the external mixed spray nozzle according to the position where the liquid to be sprayed is mixed with the air. Such nozzles are used in various fields throughout the industry.
최근에는 분사 효율은 물론 분사 표면적을 보다 확장할 수 있도록 분사액을 기체와 혼합하여 분무시키는 2유체 분사노즐의 사용이 점차 증가하고 있는 추세이다. 이러한, 2유체 분사노즐은 분사액이 기체에 의해 작은 입자 형태로 분사되므로, 분사액이 도포되는 영역을 보다 확장할 수 있는 것이다.Recently, the use of a two-fluid injection nozzle for spraying a mixture of the injection liquid and the gas to increase the injection efficiency as well as the surface area of the injection is gradually increasing. Such a two-fluid injection nozzle is capable of expanding the area to which the injection liquid is applied because the injection liquid is injected into the small particles by the gas.
특히, 2유체 분사노즐은 반도체 기판을 생산할 때 증착, 리소그래피, 식각, 화학적/기계적 연마, 세정, 건조 등과 같은 공정에서 더욱 많이 사용하게 된다.In particular, two-fluid jet nozzles are used more often in processes such as deposition, lithography, etching, chemical / mechanical polishing, cleaning, drying, etc. in the production of semiconductor substrates.
그런데, 상기와 같은 종래의 2유체 분사노즐은 분사액을 분사하기 위해서는 분사액과 기체를 동시에 공급하여야 하므로, 어느 하나의 유체를 공급하는 유압이 더 크게되면 유체가 역류하거나 유체의 분사가 원활하게 이루어지지 못하는 문제점이 있다.However, in the conventional two-fluid injection nozzle, the injection liquid and the gas must be supplied at the same time in order to inject the injection liquid, and when the hydraulic pressure supplying any one of the fluids is greater, the fluid flows back or the fluid is smoothly injected. There is a problem that can not be achieved.
또한, 종래의 2유체 분사노즐은 유체가 유입되는 하우징이 관형태로 형성되고, 이 관형태의 하우징에 복수의 노즐헤드를 결합하기 위하여 하우징을 절삭하여 헤드 결합면을 형성하므로, 하우징의 강도가 저하되고, 하우징의 길이를 길게 형성할 수 없는 문제점도 발생한다. 따라서, 이를 개선할 필요성이 요청된다.In addition, in the conventional two-fluid injection nozzle, the housing into which the fluid flows is formed in a tubular shape, and in order to join the plurality of nozzle heads to the tubular housing, the housing is cut to form a head engaging surface, so that the strength of the housing is increased. There is also a problem that can not be formed long length of the housing. Therefore, there is a need for improvement.

Since the reinforcing portions 15 for forming the nozzle coupling groove 15c and the second inflow space 11b for coupling the 40 are respectively formed in the main body 13, the durability of the main body 13 is lowered. You can prevent it.
더하여, 하우징(10)의 본체(13)와 보강부(15)를 합성수지의 사출 또는 인발 성형을 통해 일체로 형성하므로, 분사노즐(40) 결합을 위한 별도의 결합면을 형성할 필요가 없어 하우징(10)의 생산성을 향상시킬 수 있고, 하우징(10)을 보다 길게 형성할 수 있다.In addition, since the main body 13 and the reinforcement part 15 of the housing 10 are integrally formed by injection or pull molding of the synthetic resin, the housing does not need to form a separate coupling surface for coupling the injection nozzles 40. The productivity of 10 can be improved, and the housing 10 can be formed longer.

분사노즐(40)은 본체(13)에 형성되는 제1 유입공간부(11a) 및 제2 보강부(15)에 형성되는 제2 유입공간부(11b)가 각각 연통하는 유로(41), 이 유로(41)가 각각 형성되는 헤드(43) 및 연결부재(45)를 포함한다.The injection nozzle 40 has a flow path 41 in which the first inflow space 11a formed in the main body 13 and the second inflow space 11b formed in the second reinforcement 15 communicate with each other. The flow path 41 includes a head 43 and a connecting member 45 respectively formed.
유로(41)는 제1 유입공간부(11a)와 연통하도록 헤드(43)에 형성되는 제1 유로(41a)와, 제2 유입공간부(11b)와 연통하도록 연결부재(45)에 형성되는 제2 유로(41b)를 구비한다. 이때, 유로(41)의 제1 유로(41a)는 본체(13)의 유체 배출구멍(13c)과 연통한다.The flow passage 41 is formed in the first flow passage 41a formed in the head 43 so as to communicate with the first inflow space portion 11a, and in the connecting member 45 so as to communicate with the second inflow space portion 11b. A second flow path 41b is provided. At this time, the first flow passage 41a of the flow passage 41 communicates with the fluid discharge hole 13c of the main body 13.
헤드(43)는 제1 유로(41a)가 유체 배출구멍(13c)과 연통하도록 노즐결합홈부(15c)에 결합되며, 상단부에 연결부재(45)가 돌출 형성된다.The head 43 is coupled to the nozzle coupling groove 15c such that the first flow passage 41a communicates with the fluid discharge hole 13c, and the connection member 45 protrudes from the upper end thereof.

이러한, 분사노즐(40)은 제1 유로(41a)를 통해 제1 유입공간부(11a)의 유체가 분사됨에 따라 발생하는 공압차로 인하여 제2 유입공간부(11b)의 유체가 제2 유로(41b)를 통해 분사된다.In the injection nozzle 40, the fluid in the second inflow space 11b is transferred to the second flow path due to a pneumatic difference generated when the fluid in the first inflow space 11a is injected through the first flow passage 41a. Sprayed through 41b).
상기와 같은 구성을 갖는 본 발명의 실시예에 따른 분사노즐용 하우징을 이용한 2유체 분사장치의 작동상태 및 작용을 설명하기로 한다.An operation state and an operation of the two-fluid injection device using the injection nozzle housing according to the embodiment of the present invention having the above configuration will be described.
먼저, 분사노즐(40)로 유체를 분사할 수 있도록 제1 유체 공급라인(3)으로 압축공기를 공급하고, 제2 유체 공급라인(5)으로 분사용 액체를 각각 공급하면, 제1 유체 공급라인(3)을 통해 공급되는 압축공기는 제1 유입공간부(11a)로 공급되어 유체 배출구멍(13c)을 거쳐 분사노즐(40)의 제1 유로(41a)로 분사되며, 제2 유체 공급라인(5)을 통해 공급되는 액체는 제2 유입공간부(11b)를 거쳐 분사노즐(40)의 제2 유로(41b)로 분사된다.First, when compressed air is supplied to the first fluid supply line 3 so as to inject fluid into the injection nozzle 40, and liquid for injection is supplied to the second fluid supply line 5, respectively, the first fluid supply is performed. Compressed air supplied through the line (3) is supplied to the first inlet space (11a) is injected through the fluid discharge hole (13c) to the first flow path (41a) of the injection nozzle 40, the second fluid supply The liquid supplied through the line 5 is injected into the second flow path 41b of the injection nozzle 40 via the second inflow space part 11b.
그리고, 헤드(43)의 제1 유로(41a)를 압축공기가 고압으로 배출되면 제1 유로(41a)와 제2 유로(41b)에 공압차가 발생하여 제2 유입공간부(11b)의 액체가 제2 유로(41b)로 유입되면서 압축공기와 액체가 헤드(43)에서 함께 분사된다.When the compressed air is discharged at a high pressure through the first flow path 41a of the head 43, a pneumatic pressure difference occurs between the first flow path 41a and the second flow path 41b to prevent the liquid in the second inflow space 11b. Compressed air and liquid are injected together from the head 43 while flowing into the second flow path 41b.
이로 인하여, 제1 유체 공급라인(3) 및 제2 유체 공급라인(5)에서 공급되는 유체가 하우징(10)에서 각각 구획된 제1 유입공간부(11a) 및 제2 유입공간부(11b)로 각각 공급된 후, 각각의 유로(41)를 통해 배출되므로, 유체가 분사노즐(40)에서 분사될 때에만 혼합되어 배출되므로, 유체를 공급하는 압력차에 의해 어느 하나의 유체가 역류하는 것을 방지할 수 있다.Thus, the first inlet space 11a and the second inlet space 11b in which the fluid supplied from the first fluid supply line 3 and the second fluid supply line 5 are respectively partitioned in the housing 10 are provided. After each of the supply to the discharge, and is discharged through each flow path 41, because the fluid is only mixed when discharged from the injection nozzle 40, discharge of any one of the flow back by the pressure difference supplying the fluid You can prevent it.
또한, 각각의 유체가 각각의 유로를 통해 배출되므로, 하우징(10), 제1 커버부(20), 제2 커버부(30) 및 분사노즐(40)에 작용하는 유체의 압력을 보다 감소시킬 수 있어 유체의 누수 및 분사장치(1)의 파손이나 변형을 방지할 수 있다.In addition, since each fluid is discharged through each flow path, the pressure of the fluid acting on the housing 10, the first cover part 20, the second cover part 30, and the injection nozzle 40 can be further reduced. This can prevent fluid leakage and damage or deformation of the injector 1.
더하여, 합성수지의 사출 또는 인발을 통해 하우징(10)의 본체(13)와 보강부(15)를 일체로 성형할 수 있으므로, 분사노즐(40)이 결합되는 하우징(10)의 내구성 저하를 방지하고, 하우징(10)을 보다 길게 제작할 수 있다.In addition, since the main body 13 and the reinforcement part 15 of the housing 10 may be integrally formed through injection or drawing of synthetic resin, the durability of the housing 10 to which the injection nozzle 40 is coupled may be prevented. The housing 10 can be made longer.
