[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. It can also be used to remove liquid from wet solids, such as using a washing machine to spin dry wet clothes. Centrifuges are needed to separate liquid medicines from solid particles during drug development.

[0003] The drum is part of the centrifuge. In practice, the installation method of the drum and the centrifuge is rather complicated. Generally, the drum is fixed to the centrifuge by bolts or screws and nuts. This fixing method requires disassembly and assembly tools when disassembling the drum, which affects work efficiency. The drum is used to limit the tubular container. The inner diameter of the limit groove on the drum cannot be adjusted and is limited to one specification of tubular container.
