Abstract
The present invention discloses a dust removing device for two-section type dust collectors, which comprises an upstream cyclone separator and a plurality of downstream cyclone separators, wherein the downstream cyclone separators are positioned at the lower part of the upstream cyclone separator; an air outlet of the upstream cyclone separator is communicated with air inlets of the downstream cyclone separators. The present invention can simultaneously increase air quantity, reduce the volume of the body, and maintain higher dust removing efficiency. Because the downstream cyclone separators adopt the diffusing type structure, when rotating in a barrel body, airflow is in a decelerating and centrifuging condition. The present invention has the advantages of low airflow pressure loss and good dust suction effect.
