The automatic opening/shutting device(3) is positioned at inlet and outlet of the tube. In the tube having outlet(5) at the top thereof, top discharging line(6) is connected to existing bag filter(12).

Description

초 미세 분체(0.9~0.1㎛) 영역까지 분급이 가능한 건식 분급기{Dry type classifier which classify into ultra-fine powder(0.9~0.1㎛)}Dry type classifier which classify into ultra-fine powder (0.9 ~ 0.1㎛)}

본 발명은 탄산칼슘, 벤토나이트, 규사 Al2O3,등 각종 비금속광물을 포함한 모든 분체물을 0.1~1.0㎛ 이하로 입도 별로 초 미세 분급 시킬 수 있는 건식 분급기에 관한 것이다The present invention relates to a dry classifier that can classify all fine powders including various non-metallic minerals such as calcium carbonate, bentonite, silica sand Al 2 O 3 , and the like by 0.1 to 1.0 μm or less by particle size.

분급기란 분체물을 바람으로 날려 비중차이로 무거운 것은 앞쪽에 가벼울수록 먼 위치에 낙하하는 원리로 원하는 입경군 끼리 포집 하는 기계장치로 범용적으로 사용되는 것이 싸이클론 (13)인데 메이카 별로 조금씩 구조는 다르나 근본원리는 같다고 할 수 있다.A classifier is a cyclone (13) that is used as a mechanical device to collect the desired particle size groups. Although different, the fundamental principle is the same.

이러한 기존 싸이클론 방식에 의한 분급 수준은 5~10㎛ 정도 이며 1㎛이나 그 이하의 초 미세 분체의 입도분리는 불가능하여왔다.The classification level by the existing cyclone method is about 5 ~ 10㎛ and the particle size separation of ultra fine powder of 1㎛ or less has been impossible.

그래서 이러한 초 미세 분체를 얻는 데는 습식침전 분리 방식에 의존해 왔고 습식방식은 폐수발생, 가공단가 상승, 공정의 번거로움 등이 문제가 되고 있는 실정이다.Therefore, the ultrafine powder has been relied on the wet sedimentation separation method, and the wet method is a situation in which wastewater generation, processing cost increase, and troublesome process are problematic.

따라서 본 발명의 주된 목적은 건식방식으로도 습식의 침전 효과에 따른 초 미세분급과 같은 효과를 얻으므로 습식의 단점인 폐수발생, 가공단가 상승, 공정의 번거로움의 문제점을 해결코자 함에 있다.Therefore, the main object of the present invention is to solve the problems of waste water generation, processing cost increase, the hassle of the process, which is a disadvantage of the wet because it obtains the same effect as the ultra-fine classification according to the wet precipitation effect in the dry method.

제 7도는 분체 원료가 제 6도와 교체되어 7번 튜브로 원료 분체가 투입 될 경우이며, 이때는 1, 3, 5, 8, 10, 12번 튜브는 최소로 축소된 형상이며 2, 4, 6, 7, 9, 11번 튜브는 최대로 확대된 상태가 된다.FIG. 7 shows the case where the raw material powder is introduced into the seventh tube after the powder raw material is replaced with the sixth degree. In this case, the tubes 1, 3, 5, 8, 10, and 12 are in a minimally reduced shape. Tubes 7, 9 and 11 are fully enlarged.

본 발명은 튜브구조물 내부에 분체 공기를 차례대로 불어넣어 비중차에 의한 낙하방식으로 시간을 길게 또는 짧게 에어압력을 세게 또는 약하게 조절하여 초 미립 분체의 입경을 자유롭게 분리 하여 포 집 하므로 수천여종의 분체물의 초 미립화로 품질향상, 고부가가치 분체물의 학보 및 고 순도 분체물을 건식타입으로 얻을 수 있게 된다.The present invention blows powder air into the tube structure one by one in order to adjust the air pressure harder or weaker by long or short time by the specific gravity drop method to freely separate the particle size of the ultra fine powder and collect thousands of powders. The ultra-fine water makes it possible to obtain improved quality, high value-added powders and high purity powders in dry type.
