Description

약액분사노즐의 와류형성구{SWIRL GENERATION DEVICE FOR A NOZZLE}Vortex forming sphere of chemical liquid injection nozzle {SWIRL GENERATION DEVICE FOR A NOZZLE}

본 발명은 약액분사노즐의 와류형성구에 관한 것으로, 더욱 상세하게는 약액을 미세하고 균일한 입자상태로 분사하기 위해 공급되는 고압공기의 저항을 최소화함과 동시에 상기 고압공기의 균일한 공급이 가능하도록 하는 약액분사노즐의 와류형성구에 관한 것이다.The present invention relates to a vortex forming port of the chemical liquid injection nozzle, and more particularly, it is possible to uniformly supply the high-pressure air while minimizing the resistance of the high-pressure air supplied to spray the chemical liquid in a fine and uniform particle state It relates to the vortex forming sphere of the chemical liquid injection nozzle.

일반적으로 약액분사노즐은 강력한 펌핑압력을 통해 고압으로 약액을 분사하는 구조를 갖는 것이어서 이는 약액이 일방향으로만 집중되는 단점을 갖는 것으로, 미세하고 균일한 입자로 분사하기 곤란하며, 넓은 면적과 동시에 멀리 분사되도록 하기에는 구조적으로 곤란한 것이었다.In general, the chemical liquid injection nozzle has a structure in which the chemical liquid is injected at a high pressure through a strong pumping pressure, which has a disadvantage in that the chemical liquid is concentrated in only one direction. It was structurally difficult to get sprayed.

따라서 본 출원인은 상기한 단점을 해결하기 위해 국내특허출원 제10-2005-0122669호에 "고압의 공기가 통과하기 위한 통기공이 형성된 몸체와, 상기 몸체의 일단에 내장되는 와류형성구와, 상기 와류형성구를 몸체에 고정시키기 위한 캡으로 이루어지는 약액분사용 노즐에 있어서, 상기 몸체의 일단 안쪽에는 걸림턱이 형성 되도록 하고, 상기 걸림턱에는 와류형성구가 안착되도록 하되, 상기 와류형성구는 일단에 튜브 연결부를 타단에는 약액분사구를 구비하는 약액공급관과, 상기 약액공급관의 외측에 형성되어 와류형성구를 지지하기 위한 지지부와, 상기 지지부와 가까운 쪽의 직경은 작고 멀어질수록 직경이 크게 형성되는 원뿔체와, 상기 원뿔체의 일측면에 형성된 와류형성 날개로 구성되어짐을 특징으로 하는 약액분사용 노즐."를 선출원한 바 있다.Therefore, the present applicant to the domestic patent application No. 10-2005-0122669 in order to solve the above disadvantages "a body formed with a ventilation hole for the passage of high-pressure air, and the vortex forming sphere is built in one end of the body, the vortex In the chemical liquid injection nozzle consisting of a cap for fixing the forming tool to the body, one end of the body is formed so that the locking jaw is formed, the locking jaw is formed so that the vortex forming tool is seated, the vortex forming tool is a tube at one end At the other end of the connection part, a chemical liquid supply pipe having a chemical liquid injection hole, a support part formed on an outer side of the chemical liquid supply pipe to support the vortex forming port, and a conical body formed larger in diameter as the diameter is closer to the support part. And, the chemical liquid injection nozzle, characterized in that consisting of the vortex forming blades formed on one side of the cone body. " .

이때 상기 와류형성 날개는 원뿔체의 일측면 중앙에 돌출형성된 약액분사구의 주변에 형성되도록 하되, 6개의 와류형성 날개가 각각 60°의 경사각으로 엇갈리게 배치되도록 구성된다.At this time, the vortex forming wing is formed so as to be formed around the medicinal injection port protruding in the center of one side of the conical body, it is configured so that the six vortex forming wings are alternately arranged at an inclination angle of 60 °.

그러나 상기한 종래의 약액분사노즐에 있어서 와류형성구는 원뿔형상을 갖는 것이어서, 공기가 약액분사노즐을 통해 분사되기 전 원뿔체의 경사면에 부딪치면서 저항을 받게 되고, 또 상기 공기가 경사면을 타고 넘었을 때는 급격하게 직각상태로 꺾이게 되므로 와류형성구 전방에 심한 맴돌이 와류가 형성되어 진다.However, in the above-mentioned conventional chemical liquid injection nozzle, the vortex forming tool has a conical shape, and thus, the air hits the inclined surface of the conical body before the air is injected through the chemical liquid injection nozzle, and the air may cross the slope. At this time, because it is sharply bent at a right angle, a severe eddy vortex is formed in front of the vortex forming tool.

따라서 상기 맴돌이 와류는 와류형성 날개에 의해 발생하는 나선회전형 와류의 회전력을 상쇄시키는 작용을 하게 되어 오히려 약액 분사압력을 떨어뜨리게 되고, 결국 약액을 멀리 분사하는데 큰 방해가 되는 단점을 갖는다.Therefore, the eddy vortex has a function of counteracting the rotational force of the spiral rotating vortex generated by the vortex forming wing, and thus lowers the chemical injection pressure, and thus has a disadvantage of greatly hindering the injection of the chemical away.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 본 발명은 일단에 튜브 연결부를 타단에 약액분사구를 구비하는 약액공급관과, 상기 약액공급관의 외측에 형성되어 상기 튜브 연결부와 가까운 쪽의 직경은 작고 멀어질수록 직경이 크게 형성되는 원뿔체와, 상기 원뿔체의 일측면 중앙에 돌출된 약액분사구의 주변에 다수 형성된 와류형성 날개로 구성되는 약액분사노즐의 와류형성구에 있어서, 상기 원뿔체를 와류형성 날개의 경사(傾斜)방향과 동일하게 절개하여 상기 와류형성 날개와 날개 사이로 고압공기가 통과됨에 있어 방해받지 않도록 개방된 공기 유입부가 형성되도록 구성되는 약액분사노즐의 와류형성구를 제공하는 데 그 목적이 있다.Therefore, the present invention is to solve the problems as described above, the present invention is a chemical liquid supply pipe having a chemical liquid injection port at the other end of the tube connection portion, and the diameter of the side close to the tube connection portion is formed on the outer side of the chemical liquid supply tube In the vortex forming sphere of the chemical liquid injection nozzle consisting of a conical body having a larger diameter and the larger the farther, and the vortex forming blades formed around the chemical liquid injection port protruding in the center of one side of the cone body, the cone body To provide a vortex forming hole of the chemical injection nozzle which is cut in the same direction as the inclined direction of the vortex forming blades so that an open air inlet is formed so as not to be disturbed in the passage of high pressure air between the vortex forming blades and the blades. The purpose is.

또한, 상기 와류형성 날개의 사이에 위치한 원뿔체의 경사면에 수평으로 관통된 공기 유입공을 형성하여 일부의 공기는 공기 유입공을 따라 직진하고 일부 공기는 원뿔체의 경사면을 타고 넘도록 구성함으로써 맴돌이 와류를 최소화할 수 있도록 하는 약액분사노즐의 와류형성구를 제공하는 데 그 목적이 있다.In addition, by forming an air inlet hole horizontally penetrated on the inclined surface of the conical body located between the vortex forming blades, some air is straight along the air inlet hole and some air is configured to cross the inclined surface of the conical body vortex vortex The purpose is to provide a vortex forming sphere of the chemical liquid injection nozzle to minimize the.

이처럼 본 발명은 원뿔체를 와류형성 날개 면을 따라 수직으로 절개된 공기 유입부를 형성하거나 또는 상기 와류형성 날개의 사이에 위치한 원뿔체의 경사면에 수직으로 관통된 공기 유입공을 형성함으로써 고압공기는 공기저항을 최소화한 상태로 나선회전 와류를 형성하게 되며, 또한 원뿔체에 의한 맴돌이 와류를 최소화할 수 있게 되어 약액 분사압력을 떨어뜨리지 않게 되고,따라서 약액을 멀리 분사할 수 있는 매우 유용한 발명인 것이다.As such, the present invention forms a conical body with an air inlet vertically cut along the vortex forming wing surface or forms an air inlet hole vertically penetrated on the inclined surface of the conical body located between the vortex forming blades. It is possible to form a spiral rotating vortex with a minimum of resistance, and also to minimize the eddy vortex caused by the conical body, so as not to drop the chemical liquid injection pressure, thus it is a very useful invention that can inject the chemical liquid away.
