An integrated dust control device for mine unloading outlets in roadways

Abstract

This utility model discloses an integrated dust control device for ore unloading openings in roadways, including a top baffle. The top baffle has a semi-circular structure and is vertically installed at the top of the connecting roadway of the ore pass. A strip-shaped rubber dust curtain is suspended below the top baffle. A connecting opening for installing a side suction hood is provided on the lower side of the top baffle. One end of the dust removal duct is connected to the side suction hood, and the other end is connected to a wet vibrating grid dust collector. The spray dust suppression device includes a horizontal support plate and atomizing nozzles. The horizontal support plate is located above the connecting roadway of the ore pass, and atomizing nozzles are installed at intervals at the bottom of the horizontal support plate. This utility model uses the top baffle to block the airflow of dust from spreading to the main roadway. The strip-shaped rubber dust curtain and flexible sealant further seal the dust escape path. The dust is transported to the wet vibrating grid dust collector for purification through the inclined dust removal duct. Fine dust that is not captured enters the second line of defense. The atomizing nozzles spray high-pressure water mist to envelop the dust, causing it to agglomerate and settle.
