Description

Technical Field

[0001] The utility model relates to the technical field of cleaning kettles, in particular to a novel separation device for separating oil and low-density small-particle powder. Background Art

[0002] Common cleaning methods for powders include dissolution filtration and spray cleaning. When the density of the powder is relatively large relative to the cleaning liquid, the powder and the cleaning liquid easily form a suspension. The impurities in the powder are dissolved by the cleaning liquid and filtered out. High-purity powder can be obtained by drying. When the density of the powder is relatively small relative to the cleaning liquid and the particles are large, the powder floats on the surface of the cleaning liquid. By spraying the cleaning liquid, the cleaning liquid can effectively wet the powder surface, dissolve the impurities and take them away. High-purity powder can be obtained by drying.

[0003] The powder has a lower density and smaller particles than the cleaning liquid. Such powder always floats on the surface of the cleaning liquid and moves in blocks. It cannot become a suspension and cannot be removed by dissolution and filtration. At the same time, the powder has a low density and small particles. When the spray method is used for cleaning, the powder is wrapped in a ball on the surface of the cleaning liquid. The cleaning liquid cannot effectively and smoothly enter the inside of the powder ball, and the spray method cannot effectively remove the impurities.

[0004] At present, there is no special cleaning device for powders with low density and small particles, and such powders are difficult to be effectively cleaned.

[0005] Therefore, in view of the above problems, it is urgently necessary to provide a new separation device for separating oil and low-density small particle powder. Utility Model Content
