This invention relates to the field of dust removal, and more particularly to a pulse
dust collector for heavy
calcium carbonate powder production. The collector includes an outer frame, a dust hopper mounted on the lower side of the outer frame, a filter bag mounted on the upper side of the outer frame, an air
pipe connected to the upper inner side of the outer frame, an air outlet corresponding to the filter bag located on the upper side of the filter bag, an air bag mounted on the side wall of the outer frame, a pulse valve mounted on the air
pipe connected to the air bag, and an air inlet connected to the lower side of the outer frame. This invention uses a pulse valve to blow dust from the filter bag to ensure its working efficiency. A baffle initially blocks the gas entering through the air inlet, causing some dust to settle. A filter screen is provided to preliminarily remove dust from the gas upon contact with the filter bag, reducing the
workload on the filter bag. A scraper is provided to remove dust from the filter bag.
