[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids of different densities in emulsions (e.g., separating cream from milk); they can also be used to remove liquids from wet solids, such as using a washing machine to spin dry wet clothes; special ultra-fast tubular separators can also separate gas mixtures of different densities; some sedimentation centrifuges can also classify solid particles by density or size, taking advantage of the different sedimentation speeds of solid particles of different densities or particle sizes in liquids. Existing centrifuges not only have poor sealing properties, but can only perform centrifugal operations on one liquid at a time, making it difficult to meet diverse usage needs.
