CYCLONIC SEPARATING APPARATUS

摘要

The invention provides cyclonic separating apparatus (100) for separating particles from a dirt-laden airflow comprising a cyclone (102) for separating and collecting dirt and dust from the dirt-laden airflow. The cyclone (102) has an air inlet (110), an air outlet (126), a longitudinal axis (X-X) and a wall (104). The wall (104) comprises a first portion (106) and a second portion (108) spaced further from the longitudinal axis (X-X) than the first portion (106), the first and second portions (106, 108) being axially spaced along the longitudinal axis (X-X). The cyclone (102) further comprises at least one lip (114) extending from the first portion (106) of the wall (104) into a portion of the cyclone (102) surrounded by the second portion (108) of the wall (104). By providing a cyclone (102) with a wall (104) having two portions (106, 108) of different sizes and a lip (114) extending from the portion (106) with the smaller size into the portion (108) with the larger size, the risk of blockages due to re-entrainment and movement of dirt and dust within the cyclonic separating apparatus (100) is reduced.
