Dust removal device for mining equipment operation

Abstract

The utility model discloses a dust collector for mining equipment, including the box, the inside space of box is divided into upper chamber and lower chamber, the dust removal cylinder is installed through the clamping part in the upper chamber of box, the lower chamber of box is provided with the air inlet part that is in communication with the bottom cavity of dust removal cylinder, the utility model adopts the helical passageway of vertical pipe outer wall to guide the airflow to form the helical ascending motion, and can effectively disperse the dust particle in combination with the centrifugal separation effect of conical filter screen, reduces the accumulation speed of dust on the filter screen surface to avoid the problem that the traditional cloth bag type dust bag is easy to block, simultaneously, the helical structure prolongs the residence time of dust in the cylinder, improves the filtration efficiency, and the conical air cap of sealing part realizes the automatic opening and closing through the spring, and the negative pressure opens the air cap air inlet when exhausting, and the spring resets and closes the bottom when stopping, this design prevents the filtered dust from being blown back after stopping, avoids secondary pollution, and does not need manual frequent intervention.
