The working principle of the dust collector of coal mine:
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.
The structure of the dust collector of the coal mine:
Coal dust remover mainly consists of eight parts: filter room, clean gas chamber, ash storage bin, outrigger, ash cleaning device, ash disposal device, induced draft fan and 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, dust removing cloth bag, filter bag frame, filter chamber barrel,
3. Ash storage bin includes ash hopper, bearing and intake port.
4. Dust removal devices include: rapping motor, rapping rod and machine parts.
5. The ash disposal device includes: screw conveyor and star type unloader.
6. The control system includes: cable, control cabinet
Dust collector parts of coal mine:
1. The filter bag of the coal dust collector is rectangular and the material is antistatic needle felt.
2. The way of clearing ash is to shake off the dust.
3. All motors are explosion-proof type.
4. The ash unloading device adopts screw conveyor and star type unloader.
5. Control cabinet for PLC control, with automatic control and manual control, two switching.
The operation of the dust collector of the coal mine:
(1) check the lubrication points before driving.
(2) start the exhaust fan before dust emission. When working continuously for 0.5 to 2 hours, the dynamic vibrator will be struck once or 3~5 seconds.
The maintenance of the dust collector of the coal mine:
(1) strict attention should be paid to the sealing of the seals. No air leakage is allowed.
(2) according to the actual situation, check the door regularly to check whether the bag is damaged, and replace the new bag in time when it is damaged.
(3) when replacing the cloth bag, we must pay attention to no breaking.
