What parts does a cyclone dust collector consist of? What is the principle of cyclone dust collector?

An ordinary cyclone dust collector is composed of four parts: the inlet, the simplified body, the cone, and the discharge pipe (inner cylinder).

The cyclone dust collector uses the centrifugal force generated by the rotation of the air flow to separate dust from the dust-containing air flow. After the dust-containing airflow enters the dust collector along the tangential direction from the dust collector inlet, it rotates downward along the outer wall. This downward rotating airflow is called the outer vortex. After the outer vortex reaches the bottom of the cone, it turns upward, rotates upward along the axis, and is finally discharged from the discharge pipe. This upward airflow becomes an inner vortex. The downward outer vortex and the upward inner vortex rotate in the same direction, that is, clockwise or counterclockwise. When the airflow rotates, the dust is thrown toward the outer wall under the action of centrifugal force. The dust that reaches the outer wall falls into the ash hopper along the wall under the combined action of the downward swirling airflow and gravity.
