[0002] A cyclone is a separation device that uses centrifugal force. It is mainly used in scenarios such as solid-liquid separation, liquid phase separation, and particle classification. It introduces the mixed material into a cylinder to generate a strong rotating flow, so that materials of different densities are layered. In solid-liquid separation, the cyclone can separate solid particles floating in the liquid. In liquid phase separation, the cyclone can separate different liquid mixtures. The bottom flow port is an important component of the cyclone and is usually located below the cyclone. The function of the bottom flow port is to control the inlet flow of the cyclone, ensure the stability and uniformity of the fluid inside the cyclone, and reduce the vortex and rotation speed at the outlet of the cyclone.
