Principle of dust collector of coal mine crusher
The dust containing gas is filtered through the air bag of the air inlet of the unit and filtered through the cloth bag. The clean gas is discharged from the dust collecting cloth bag to the ventilation chamber and then drained by the fan. Therefore, the dust dust is hinded to be attached to the outer wall of the bag. To increase the resistance of cloth bags, it is advisable to vibrate and clean the rapping mechanism every 0.5 to 2 hours at a time of 3~5 seconds. The interval time can be adjusted according to the dust concentration. In order to reduce drag and improve the efficiency of dust removal, the screw conveyor and star type discharger are discharged.
Structure of dust collector of coal mine crusher
The structure of the dust collector is mainly composed of eight parts: the filter room, the clean gas chamber, the ash storage bin, the outrigger, the ash cleaning device, the ash discharging device, the induced draft fan and the control system.
1) the clean gas chamber includes: the side cover of the dust collector, the cleaning chamber for changing the bag into the hole, and the purified air outlet.
2) the filter room includes: filter bag fixing plate, dusting cloth bag, filter bag frame, filter chamber barrel,
3) ash storage bin includes ash hopper, bearing and intake port.
4) the ash removal device includes: rapping motor, rapping rod and machine parts.
5) the ash unloading device includes a screw conveyor and a star type discharger.
6) the control system includes: cable, control cabinet
