Abstract

The present invention discloses a dust cleaning device for external installation type dust collectors, which comprises an upstream cyclone separator and at least two parallel external downstream separators, wherein an air outlet of the upstream cyclone separator is communicated with air inlets of the downstream cyclone separators. The present invention can increase air quantity simultaneously, reduce the volume of the body, and simultaneously, 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.

Description
