When the flow sensor 15 detects that the air flow above the corresponding outer cover 10 is reduced, corresponding holes are closed through an electric control valve, then the electric telescopic pipe 16 is started to enable the electric telescopic pipe 16 to extend, a rubber ring 19 on the hollow plugging disc 14 abuts against the top of the sleeve 11, at the moment, the sleeve 11 is plugged by the rubber ring 19 and the air injection box 18, cleaning gas in the hollow plugging disc 14 enters the air injection box 18 and then enters the hollow rotating ring 20, finally enters the hollow rotating ring 20, the hollow rotating ring 20 is positioned between the sleeve 11 and the filter cylinder 12, cleaning gas blown out of the hollow rotating ring 20 enters the filter cylinder 12 from the lateral side outside the filter cylinder 12, dust filtered on the inner lateral wall of the filter cylinder 12 is blown off, and the dust is separated from the inner wall of the filter cylinder 12;
Along with the ejection of the cleaning gas in the air nozzle 21, the hollow rotating ring 20 is driven to rotate on the gas injection box 18, so that the ejected cleaning gas is driven to rotate, a rotational flow is formed between the sleeve 11 and the filter cylinder 12, the cleaning gas can be blown to all sides of the filter cylinder 12, a centrifugal force with certain strength can be generated, the backwashing effect of the cleaning gas is improved, and the filter cylinder 12 is cleaned more thoroughly;
along with the movement of the gas injection box 18, the gas injection pipe 22 and the baffle plate 23 are driven to move, so that the first permanent magnet ring 24 on the baffle plate 23 is propped against the permanent magnet disk 26, the first permanent magnet ring 24 can adsorb the permanent magnet disk 26 and drive the permanent magnet disk 26 to move, so that the permanent magnet disk 26 is separated from the second permanent magnet ring 28, and the blocking effect of the permanent magnet disk 26 on the gas guide box 25 is lost;
Then, the back flushing stage, the back flushing and purging concurrent stage and the full blowing stage are sequentially performed, so that the back flushing is performed, and during the back flushing stage, all the cleaning gas sprayed from the gas injection pipe 22 enters the gas guide box 25 through the gas inlet holes, the cleaning gas is sprayed from the gas injection pipe 29 only, and the high-pressure cleaning gas sprayed from the gas injection pipe 29 vibrates the corrugated plate 31 through the corrugated plate 31.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
