Working principle: when the device is used for automatic ash discharging and dust removing, reverse blowing and dust removing are firstly carried out, the pulse electromagnetic valve 6 is opened by the pulse controller 9, compressed air in the compressed air storage bag 7 is sprayed into the separation pipe 16 from the sealing cover 12 after passing through the pulse electromagnetic valve 6, the blowing pipe 5, the arc-shaped pipe 10 and the hose 11, and at the moment, air flow enters the inner side of the filter 14 from the outer side of the filter 14, and then dust on the inner side of the filter 14 is blown out;
then, reverse blowing is carried out, the pulse controller 9 controls the air passage at the lower side of the three-way electromagnetic valve 51 to be opened, compressed air in the compressed air storage bag 7 enters the volume cavity of the shell 1 after passing through the pulse electromagnetic valve 6, the blowing pipe 5 and the three-way electromagnetic valve 51, and at the moment, air flow enters the outer side of the filter 14 from the inner side of the filter 14, and then dust at the outer side of the filter 14 is blown out;
then, ash is discharged, the power supply of the first electromagnet 19 is firstly disconnected, the ash discharging plate 15 falls under the action of gravity, the ash discharging plate 15 drives the limiting rod 17 to fall, when the limiting rod 17 starts to drive the buffer spring 18 to compress, the ash discharging plate 15 starts to decelerate, meanwhile, under the action of the elastic force of the buffer spring 18, the limiting rod 17 drives the ash discharging plate 15 to vibrate up and down, the ash discharging plate 15 drives the filter 14 to shake up and down, and further, sticky dust on the filter 14 can be shaken off, and when the ash discharging plate 15 moves down, a gap is generated between the ash discharging plate 15 and the separation tube 16, the dust can flow out along the gap and enter the volume cavity, and the filter 14 is dedusted by reverse wind in the process;
when the impact dust removal is carried out, firstly, the first electromagnet 19 is electrified, the first electromagnet 19 adsorbs the dust discharging plate 15 through magnetic force, then the second electromagnet 23 is electrified in a periodical power-off mode, when the second electromagnet 23 is powered off, the reset spring 25 pushes the oscillating contact 26 to extend out of the oscillating groove and impact the filter 14, when the second electromagnet 23 is electrified, the second electromagnet 23 drives the oscillating contact 26 to retract into the oscillating groove through the magnetic force adsorption guide rod 24, the filter 14 is impacted through the oscillating contact 26, and the sticky dust of the filter 14 can be removed.
