Technical Field
The invention belongs to the technical field of dust removal equipment, and particularly discloses a cyclone dust collector.
Background
Cyclone dust collectors utilize centrifugal force generated during the rotation of the airflow to separate dust from the dust-containing airflow. The dust-containing air flow enters the dust remover from the dust remover inlet along the tangential direction, and then makes a rotary motion downwards along the outer wall, the downward rotary air flow is called an outer vortex, after the outer vortex reaches the bottom of the cone, the outer vortex rotates upwards along the axis, and finally is discharged from the discharge pipe, the upward air flow becomes an inner vortex, the downward outer vortex and the upward inner vortex are identical in rotary direction, namely, the uniform clockwise or the uniform anticlockwise, when the air flow makes a rotary motion, dust is thrown to the outer wall under the action of centrifugal force, and the dust reaching the outer wall falls into a dust hopper along the wall surface under the combined action of the downward rotary air flow and gravity.
The cyclone dust collector consists of an air inlet pipe, an air outlet pipe, a cylinder body, a cone and an ash bucket. The smaller the diameter of the cylinder body is, the better the dust removing effect of the cyclone dust remover is.
