8. The working method of the environment-friendly aluminum ash dust-settling screening equipment is characterized by comprising the following steps of:

the method comprises the following steps: controlling an external power supply to enable a bidirectional motor (7) to start working, enabling the bidirectional motor (7) to drive a lower belt pulley (12) to start working through a transmission belt (11) outside a driving shaft (10), and then enabling a coaxial rod (14) inside the belt pulley (12) to start rotating, so that the coaxial rod (14) drives a crushing wheel (15) inside a screening box (1) to start working;

step two: aluminum ash is put into the equipment from the inside of the feed hopper (4), when the crushing wheel (15) works, the sector gear (19) drives the driven gear (201) to rotate through transmission among the gears, and the driven gear (201) enables the primary screen (17) and the sieving net (18) on the upper side and the lower side to reciprocate up and down through transmission among the mechanisms in the rotating process, so that the primary screen (17) and the sieving net (18) sieve the aluminum ash;

step three: in the screening process of the primary screen (17), the primary screen (17) shakes aluminum ash, so that the aluminum ash can be screened rapidly, meanwhile, when the bidirectional motor (7) works, the bidirectional motor (7) drives the gear plate (131) to rotate, the rotating wheel cylinder (135) rotates through transmission between gears, at the moment, iron slag in the aluminum ash shaken by the primary screen (17) is attracted by the magnet (136) inside the rotating wheel cylinder (135), then, iron sheets are adsorbed outside the rotating wheel cylinder (135) and removed, and the aluminum ash is recovered through treatment of the scrap removing plate (137);

step four: in the process of removing iron slag, the hollow toothed plate (134) on the fixing plate (133) rotates through transmission between the gears, the hollow toothed plate (134) drives the suction fan (138) to rotate, the suction fan (138) absorbs dust generated during blanking and dust generated during crushing, and the dust is discharged after impurity removal through a dust filtering net in the air outlet pipe (5);

step five: and elementary screen cloth (17) sieve remaining large granule aluminium ash through elementary screen cloth (17) both sides gliding entering into the inside of shielding plate (16), mutually support through broken wheel (15) and shielding plate (16), carry out meticulous smashing to large granule aluminium ash, the aluminium ash drippage after smashing screens the inside of net (18), drive through follower (20) and screen the net (18) and carry out screening once more to improve the utilization ratio of aluminium ash and the screening efficiency of equipment.
