20150096446 | DUST-COLLECTING DEVICE OF A SECONDARY DUST-COLLECTING MACHINE - A dust-collecting device of a secondary dust-collecting machine includes a wind guide barrel having a wind intake and a bottom disposed with a dust-collecting barrel. The wind guide barrel further has its topside mounted with a wind duct installed thereon with a blowing fan and connected with a dust-collecting box, which has a plurality of centrifugal type dust collectors set therein. Thus, outside dust accompanying air can be sucked into the wind guide barrel through the wind intake by the suction of the blowing fan to have the dust with comparatively large diameter first collected by the dust-collecting barrel. Then, the remaining dust with lighter mass will be collected for a second time by the centrifugal type dust collectors and filtrated by the filter screen for completely filtrating and removing the dust from the operation environment. | 04-09-2015 |
