| Summary: | Cyclone technology have been widely use in the industry or home appliance for separating dust from the dirty air. High performance cyclone requires high efficiency cyclone to separate dust. To achieve high efficiency cyclone, the cyclone geometry need to be modified. One of the geometry that can be modified to improve the cyclone efficiency is the cyclone bottom diameter. The modification of this geometry is by making it smaller. Smaller cone bottom diameter will increase the risk of having dust to get clogged inside the cyclone. Thus the mechanism of dust removal during the cyclone operating condition have been developed. This mechanism using the flexible tip that will be attached to the cyclone. Due to its flexibility, the dust will not get clogged as the tip will vibrate and deformed when excited by cyclone internal high velocity. This study is focusing on the understanding the characteristic of the flexible tip that used in a vacuum cleaner appliance. The major area of this study is to simulate and analyze the natural frequency and mode shape of the flexible tip. A few variable parameter and geometries will be design for simulation. To comprehend the study, a finite element software is used. The different material of flexible tip and operational flowrate will be used along with the change in tip geometry mainly on the thickness, length and bottom diameter. The contraction mode shape that is beneficial for self-cleaning purpose will be identify. |
