Description

초음파 분말 제조기Ultrasonic powder maker

본 장치는 금속 등을 용융하여 로 ①에서 분출·낙하시킬 때, 랭개빈형 전 왜 초음파 진동자 및 혼 ②에서 진동을 일으키게 하여 초음파 진동혼에 부닥치는 용융체에 초음파 에너지를 주어 용융체가 미세한 입자로 만들어지게 하는 장치이다. 이 장치에서 제조된 분말이 비산시 초음파 혼 ②에 달라붙으면 진동 에너지가 쇄퇴되므로 그렇지 않도록 가이드 판 ③으로 보호한다.This device melts metals and ejects them from the furnace ① and causes them to vibrate in the laminar type pre-warm ultrasonic vibrator and horn ② to give ultrasonic energy to the melt facing the ultrasonic vibration horn to make the melt into fine particles. Device. If the powder produced in this device clings to the ultrasonic horn ② during scattering, the vibration energy is decayed, so protect it with the guide plate ③.

절연 냉각유는 냉각조 출구 ⑥을 나와 공급 펌프 ⑪을 거쳐 인터쿨러(intercooler)⑨를 나온 저온 냉각유가 수분리기 ⑭를 지나 공급구 ④에서 절연 냉각유 냉각조 ⑤로 공급되어 초음파 진동자 및 혼 ②를 30℃ 이하로 유지시키고 절연 냉각유 출구 ⑥을 거쳐 다시 인터쿨러 ⑨로 되돌아간다.The low temperature coolant from the coolant outlet ⑥ through the feed pump ⑪ and out of the intercooler ⑨ passes through the water separator 공급 to the insulated coolant cooler ⑤ from the supply port ④ to supply the ultrasonic vibrator and the horn ②. Maintain below ℃ and return to intercooler ⑨ through insulated cooling oil outlet ⑥.

이 장치는 금속 등 용융체를 용융로에서 용융시킨 후 자유 낙하시키는 아래쪽에 초음파 혼(ultrasonic horn)을 설치하여 진동 에너지를 가함으로서 낙화 용융체가 위치 에너지와 초음파 진동 에너지를 받아 용융체가 미세한 분말로 만들어지게 하는 장치이다.This device installs an ultrasonic horn at the bottom where a melt such as a metal is melted in a smelter and free-falls to apply vibration energy so that the fallen melt receives potential energy and ultrasonic vibration energy to make the melt into fine powder. Device.

이 장치는 전원이 공급되면 초음파 진동 발생 장치가 초음파 진동자 및 혼에 초음파 진동 에너지를 전달하게 된다. 그러면 자유 낙하하는 용융체가 초음파 진동부 즉, 혼에 부닥치면서 충격력과 초음파 진동력을 동시에 받아 용융체 내부에서 분열·비산되어 매우 미세한 분말로 분산되게 된다. 이 분산된 미립자를 공기 송풍 장치 등으로 냉각시켜 분말(powder)로 만들어진다.When the power is supplied, the ultrasonic vibration generating device transmits ultrasonic vibration energy to the ultrasonic vibrator and the horn. Then, the free-falling melt collides with the ultrasonic vibrator, that is, the horn, and receives the impact force and the ultrasonic vibration force at the same time, thereby splitting and scattering in the melt and dispersing it into a very fine powder. The dispersed fine particles are cooled into an air blower or the like to form a powder.

이 초음파 진동자는 주파수와 진폭의 크기에 따라 진동 에너지가 다르므로 주어진 용융체에 따라, 또 분말의 입경 크기에 따라 고유 진동수 및 진폭을 알맞게 설정하여야 한다.The ultrasonic vibrator has different vibration energy depending on the frequency and amplitude, so the natural frequency and amplitude should be appropriately set according to the given melt and the particle size of the powder.

일반적으로 용융체로 많은 분말량을 생산하고자 할 때에는 고유 진동 주파수가 낮고 진폭이 크도록 설계하여야 하고, 분말 입경이 매우 미세한 분말을 필요로 할 때에는 고유 진동 주파수가 크도록 설계·제작하여야 한다.In general, when a large amount of powder is to be produced by the melt, it is designed to have a low natural vibration frequency and a large amplitude. When a powder having a very small particle size is required, the natural vibration frequency should be designed and manufactured.

또한 진동자가 임계 온도를 넘게 되면 진동을 하지 않으므로 진동자 온도가 항상 30℃ 이하로 유지되도록 진동자 주위에 냉각을 시켜야 한다. 그런데 이 초음파 진동자는 음극과 양극이 대치되어 있으므로 그 부위에 냉각을 시키려면은 전기적으로 완전 절연되는 유(oil)로 냉각하여야 한다. 따라서 이 장치의 냉각유는 절연성이 뛰어난 냉각제를 이용하여 항상 저온으로 냉각되도록 설계되어야 한다.In addition, since the vibrator does not vibrate when it exceeds the critical temperature, it should be cooled around the vibrator so that the vibrator temperature is always kept below 30 ° C. However, the ultrasonic vibrator has a cathode and an anode replaced, so to cool the portion, the ultrasonic vibrator must be cooled with an electrically insulated oil. Therefore, the coolant in the device must be designed to always be cooled to low temperatures using a highly insulating coolant.

따라서 본 장치는 효율적인 작동을 위하여 더머커플을 센서로 이용하는 온도 제어 장치로 절연 냉각유의 온도를 일정하게 유지하도록 인터쿨러 및 냉각팬을 자동적으로 구동시키는 공·수냉식 냉각장치를 갖추고 있다.Therefore, this device is a temperature control device that uses a decoupler as a sensor for efficient operation, and is equipped with an air-cooled cooling device that automatically drives an intercooler and a cooling fan to maintain a constant temperature of the insulating cooling oil.

이와 같이 최적의 초음파 진동 에너지를 얻도록 설계함으로서 금속 등 용융체를 미세한 분말로 연속적으로 만들게 된다.By designing to obtain the optimal ultrasonic vibration energy as described above, the melt such as metal is continuously made into fine powder.
