[0002] Centrifugal micropowder separators [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fine powder centrifuge, and more particularly, to an apparatus for recovering fine powder remaining in a solution after a work such as a metal working or a liquid phase reaction process, And a fine powder centrifugal separator for separating the solution.

After operations such as metal working or liquid phase reaction processes, the powders in the used solution must be recovered and the powders in the solution are collected to provide for reuse or effective treatment and discharge of the solution. However, in the past, various kinds of filters have been used to collect powders, and fine powders are floating in the solution even if a fine filter is used. Therefore, in order to overcome this problem, a hydraulic compression method or a centrifugal separation method An apparatus for removing powders was provided.

Korean Patent No. 10-0289134 ("Rapid Centrifuge"), which is a rapid centrifugal separator for centrifuging the mackerel and moisture using a centrifugal separation method as described above, is disclosed. As shown in Fig. 1, the above-mentioned method includes an inlet 1, an outlet A 2, an outlet B 3, a high speed swivel 4, a conveying means 5 and a dispersing member 6. To briefly explain each part of the above-mentioned method, the processed material is introduced into the rapid centrifuge through the inlet 1, and the processed material is passed through the high speed spinning machine 4, the conveying means 5, (2) and the discharge port (B) 3 through the discharge port (6).

Although the above-mentioned method has the advantage of significantly increasing the processing capacity of the processed material by providing a large number of power devices connected to the high speed spinning machine 4, the conveying means 5 and the dispersing member 6, There is a drawback that excessive power is required. This increases the cost of recycling the solution using a centrifuge in the field, leading to a burden on the worksite. In addition, since the fine powder and powders may be caked, the machine may not operate properly. Therefore, it is necessary to clean the inside of the machine from time to time. In the state where the conveying means and the like are provided, it is difficult for the operator to clean the machine.
